一、選題質量：
(1)我的專業(yè)是機械設計制造及其自動化，而且更偏向于礦山機械，再加上曾有去礦山實習的經(jīng)歷，這次我選的礦井提升機的設計題目非常符合我專業(yè)要求，同時也體現(xiàn)了畢業(yè)設計實現(xiàn)理論知識和實際工程相結合的宗旨。
(2)由于本題目和我所學專業(yè)非常接近，在所學礦山機械、故障診斷等科目中有多的設計，所以難度并不大。但是由于需要對整個主井提升系統(tǒng)進行選型計算，以及對電機、離合器和減速箱部分進行重點設計計算，工作量還是蠻大的。不過我一定會按時按量完成畢業(yè)設計任務。
(3) ) 煤炭在我國的能源消費的結構中占有極大的比重，是工業(yè)發(fā)展的原材料及能源來源，而礦井提升機是煤炭開采中的咽喉設備，它是地面和井下的唯一通道，重要性不言而喻。礦井提升機不僅輸送開采出來的煤炭和生產(chǎn)設備，而且擔負人員上下井運送的重任，一旦此處出現(xiàn)故障就會影響生產(chǎn)的正常進行，造成經(jīng)濟損失，甚至造成人員傷亡的嚴重后果。當前我國的一些老舊產(chǎn)品仍在使用，其運行年久日深，結構落后，容易發(fā)生故障，抑制了煤炭業(yè)的高速發(fā)展，對國民經(jīng)濟發(fā)展非常不利，安全可靠的新型提升機已成為社會有志之士的關注焦點之一。故研究礦井提升機不僅具有極大的社會意義而且對實驗室的建設也有重大的意義。
二、開題報告完成情況：
開題報告已經(jīng)圓滿完成,并通過了指導老師的檢查。
三、階段性成果：
1、對所選課題已經(jīng)有了比較深刻的認識，按照規(guī)定計劃進行中。
2、通過老師的指導和幫助分析，已收集了大量的資料和文獻，為設計順利完成做好準備。
四、存在主要問題：
在設計系統(tǒng)過程當中，我深感部分資料和知識的缺乏，尤其是圖文幫助理解所存在的問題及應對策略，資料中不是一筆帶過就是籠統(tǒng)的泛泛而談，很少有專業(yè)細致的探討，而且圖文幫助系統(tǒng)多種多樣，應用廣泛，使我一時無所適從。有的資料甚至跟自己的設計內容文不對題差異很大。最后決定棄異存同，將其共性作為本次設計的重點，擇其主要功能和特點進行設計。
另外，我還應該多加強自己對設計方案的優(yōu)化能力，使設計的系統(tǒng)更完美。同時，還應該再加強與指導老師的交流和溝通，更深層次的認識設計的宗旨。
總之，我相信自己會保持積極的態(tài)度，在指導老師的悉心點撥下，能夠快速有效展開接下來的設計流程，順利完成畢業(yè)設計工作。

一、 選題的目的和意義：
礦井提升機是礦井運輸?shù)闹匾O備，是溝通礦井上下的紐帶的。隨著科學技術進步和礦井生產(chǎn)現(xiàn)代化要求的不斷提高，人們對提升機工作特性的認識進一步深化，提升設備及拖動控制系統(tǒng)也逐步趨于完善，各種新技術、新工藝逐步應用于礦井提升設備中。
單繩纏繞式提升機在礦井生產(chǎn)中使用比較廣泛，也是最早出現(xiàn)的一種，它工作可靠，結構簡單，適用于淺井及中等深度的礦井。由于國內許多礦井已采掘多年，礦井深度、產(chǎn)量都與最初設計有所變化，所以了解單繩纏繞式提升機系統(tǒng)設計，對于礦井提升機的改造是十分必要的，對于我今后在的工作也是很有幫助。
在畢業(yè)設計的過程中，更要多學習提升機方面的知識，盡量多到現(xiàn)場去了解提升機，為今后的工作和學習打下堅實的基礎。
二、 國內外研究綜述：
目前國產(chǎn)大型礦井提升機的特點是：全焊接的卷筒，遠距離操縱的液壓卷筒調繩離合器，圓弧齒輪減速器，自整角機的深度指示器，盤形制動系統(tǒng)等等。我國提升機近年來雖有一定改進提高，但還有很多技術問題需要研究和提高。當前我國提升機的研制工作，主要是在提高安全可靠性基礎上，延長基礎零件的壽命；在有條件的礦井逐步提高自動化程度；積極發(fā)展新的品種規(guī)格，提高零部件的標準化、系列化、通用化程度，并逐步采用國際標準；加速建立和完善試驗和測試基地；由單機向系統(tǒng)成套研制過度等等。
國外礦井提升機的發(fā)展，主要是在提高可靠性基礎上提高結構性能和自動化水平，產(chǎn)品品種多樣化，在規(guī)格上向經(jīng)濟性好的大型化發(fā)展，零部件的標準化、系列化、通用化程度進一步提高，以達到小批量產(chǎn)品能成批生產(chǎn)，降低成本增加利潤。設備大多數(shù)成套設計、配套供應，國際間技術合作和配套進一步擴大。為使產(chǎn)品更有競爭力，大量和不斷采用新技術、新材料、新工藝。在新的提升系統(tǒng)上，國外研究連續(xù)提升、風動提升、液壓提升等。目前國外礦山日益走向集中化、大型化，礦山提升機隨之向體積小、重量輕、能力大、安全可靠和高度自動化的方向發(fā)展。

2.1 Process design principles
Design Technology program should be to ensure product quality at the same time, give full consideration to the production cycle, cost and environmental protection; based on the enterprises ability to actively adopt advanced process technology and equipment, and constantly enhance their level of technology.
Engine block machining process design should follow the following basic principles:

(4) The whole line used in all wet processing, using standalone BTA, high-precision machining processes critical horizontal machining center with constant cooling and to install high-precision high-voltage double-circuit band-pass fine filtration system, all with high-pressure processing center in the cold.
According to the technological characteristics of automobile engine cylinder block and the production mandate, the engine block machining automatic production line is composed of horizontal machining center CWK500 and CWK500D machining centers, special milling / boring machine, vertical machining centers matec-30L and other appliances.
(1) top and bottom, and tile covered only the combination of aperture rough milling machine dedicated to this machine to double-sided horizontal milling machine, using moving table driven parts, machine tools imported Siemens S7-200PLC system control, machine control cabinet set up an independent, cutting automate the process is completed and two kinds of automatic and adjust the state;
(2) high-speed horizontal machining center machining center can be realized CWK500 the maximum flow of wet processing, but because of equipment, automatic BTA treatment system through the built-in tray under the wide-type chip conveyor and the completion of the machining center can be dry processing; machine tool spindle speed 6000r/min, rapid feeding speed 38m/min;

(6) high-speed horizontal machining center spindle CWK500D highest speed 15000r/min.
2.2 Process design basis
Affect the engine block part of the process design factors are manifold. Specifically, can be understood from the following aspects.
(1) product object, product drawings and technical documents related to the complexity of the engine block under the precision requirements of the process to take corresponding measures. Production targets for the four-cylinder automobile engine cylinder block;
(2) the production program, the production of the nature and type of production of the engine block the production program of 400 million;
(3) The annual effective system of work equipment, working for 320 days, with an average equipment loading rate of 80%, two shifts, 16 hours / day.
Engine block complex structure, high precision, large size, is thin-walled parts, there are a number of high precision plane and holes.
Engine block machining process characteristics: mainly flat and the hole processing, processing of flat generally use planing, milling methods such as processing, processing of hole used mainly boring, processing and multi-purpose drilling holes. As the cylinder complex structure, so how to
ensure that the mutual position of the surface processing precision is an important issue.
3.1 The selection of blank
Engine block on the materials used are generally gray cast iron HT150, HT200, HT250, there is also cast aluminum or steel plate, this engine block using high-strength alloy cast iron. Cylinder in the processing prior to aging treatment in order to eliminate stress and improve the rough casting mechanical properties.
Improve the rough accuracy, reduction of machining allowance, is to improve the automated production line system productivity and processing quality of the important measures. As the foreign box-type parts of rough quality and high precision, and its production-line system has been implemented directly on the blank line, not only eliminating the need for blank check device also saves the rough quality problems due to waste of machining time, increase overall efficiency. Therefore, the refinement of rough is to improve the productivity of the most promising way out. For the engine block production line, can be rough in parts on-line pre-milling six face, removing most of the margin, to facilitate direct on-line parts.
3.2 machining process selection and processing of the benchmark
Choose the right processing technology base is directly related to the processing quality can ensure the parts. Generally speaking, process benchmarking can be divided into coarse and fine reference base.
(1) The baseline for the on-line thick rough, which is particularly important the choice of benchmark crude, if crude benchmark choice unreasonable, will the uneven distribution of machining allowance, processing and surface offsets, resulting in waste. In the cylinder production line, we have adopted for the coarse side of the base;
(2) refined the base of this box for the engine block parts, the general use of “side two sales” for a full range of uniform benchmarks. For the longer automated production line system, due to pin holes in the course of the wear and tear caused by inaccurate positioning, therefore, will be divided into
2-3 segment pin holes used. In the cylinder pin hole of the process, we have adopted to the side, bottom and the spindle hole positioning, in the processing center on the process.
3.3 Machining Processing Stages and processes of the arrangements
Often a part of many apparent need for processing, of course, the surface machining accuracy are different. Processing of high precision surface, often after repeated processing; As for the processing of the surface of low precision, only need to go through one or two on the list. Thus, when the development process in order to seize the “processing high precision surface,”this conflict, the reasonable arrangement processes and rational division stage of processing. Arrange the order of the principle of process is: after the first coarse refined, the first surface after the hole, the first benchmark other. In the engine block machining, the same should follow this principle.
(1) roughing stage engine block machining process, the arrangements for roughing process, to fully carry out rough rough, trim most of the margin in order to ensure production efficiency;
(2) semi-finishing phase of the engine block machining, in order to ensure the accuracy of some important surface processing, and arrange some semi-finishing operations, will be required accuracy and surface roughness of the surface of the middle of some processing to complete, while demanding the surface of semi-finished, to prepare for future finishing;
(3) The finishing stage of requiring high accuracy and surface roughness of the surface processing;
(4) secondary processing, such as small surface screw holes, you can finish of the major surface after the one hand, when the workpiece deformation process little impact at the same time also reduced the rejection rate; In addition, if the main surface of a waste, these small the surface will not have to be processed, thus avoiding a waste of man-hours. However, if the processing is very easy for a small surface bumps the main surface, it should be placed on a small surface finish prior to the main surface finishing;
(5) should make proper arrangements for secondary processes such as product inspection process, in part roughing stage, the key process before ining Processing Stages and processTand after processing, spare parts all the processing has been completed, should be appropriate arrangements.
Stage of processing division, has the following advantages: First, it can take measures to eliminate the rough workpiece after the stress, to ensure accuracy; second, finishing on the back, and will not damage during transport the surface of the workpiece has been processed; again, first roughing the surface defects can be detected early and promptly deal with rough, do not waste working hours. But most small parts, do not sub very thin.
3.4 cylinder surface of the main processing and secondary processes
Cylinder surface and support the main processing operations are:
(1) plane processing At present, the milling of engine blocks is the primary means of planar processing, domestic milling feed rate is generally 300-400mm/min, and foreign 2000-4000mm/min milling feed rate compared to far cry, to be on increasing, therefore, improve the milling feed rate, reduce overhead time is to improve the productivity of the major means of finishing a number of plane engine block when the milling feed rate to reach 2399 mm / min, greatly improved efficiency; Top surface of the cylinder milling is a key process in the process, the flatness requirements for 0.02/145mm, the surface roughness of Ra1.6um. Processing in the cylinder, the use of side and spindle bearing bore positioning, top, bottom and middle vagay only aperture while processing used in the processing line outside of the knife device can better meet the engine block machining accuracy ;
(2) General holes machining holes in general are still using the traditional processing of drilling, expansion, boring, reaming, tapping and other craft approach. Issues in the design process of specific programs, use of coated cutting tools, cutting tools and other advanced tools within the cooling, and using a large flow of cooling systems, greatly improving the cutting speed, improved productivity; he key process before ining ProceW
(3) deep hole processing of the traditional processing method is used to grade twist drill feed, low efficiency of their production, processing and quality is poor. The deep hole in the engine block processing, the use of gun drilling process;
(4) The three-axis machining holes for the cylinder-axis machining holes holes of high precision, long working hours of the restrictive process. Thus, work arrangements, processing methods, tools and so on should be special attention. All cover pre-processing, that is, semi-circular hole and the cylinder block main bearing cap of the shortage of processing, its main purpose is to remove blank margin, release stress, to prepare for the post-order processing; in crankshaft machining processing center hole, using double-sided Boring, boring the first holes in the crankshaft hole at one end to 1 / 2 length, and then turn 180 degrees workbench, from the other end and then bore another 1 / 2 length.
(5) The cylinder bore machining cylinder hole cylinder machining processing is a key process in the one, under normal circumstances, the machining process as a rough boring, semi-fine boring, precision boring and honing. Cylinder bore wall for the early detection of casting defects, eliminate stress, should be thick cylinder boring holes in advance; due to the structural characteristics of the different cylinder bore, must be in honing process to improve the cylinder bore surface quality. In the high-volume production, the cylinder bore honing generally use the multi-axis grinding machine or honing Automatic Line. Here we use honing automatic lines, from the coarse-heng. Fine-heng and testing equipment, composed of three;
(6) Cleaning Cleaning is divided into wet cleaning and dry cleaning. Machining cylinder automatic production line using a large flow of wet cleaning;
(7) Detect points outside the line detection and line detection of two kinds. Quality inspection in the engine block, according to the actual vity; he key process before iniXsituation with lines outside the detection, the main use of coordinate measuring machine integrated measurements of the cylinder, each 200 samples 1-5 pieces, each class random one. 3.5 cylinder processing the choice of cutting parameters
Engine block choice of cutting parameters including cutting speed, feed rate and feed rate option. As the processing equipment is used in high precision and rigidity of machine tools and high-speed machining centers in order to ensure the efficiency of cutting may be the appropriate choice of cutting a larger amount.
The main processing engine block surface plane and bearing bore, cylinder bore holes such as the processing, while the plane and bearing bore, cylinder bore of the processing method is mainly milling and boring, so the discussion here, the choice of cutting parameters are mainly milling and Boring choice of cutting parameters.
(1) milling the choice of the amount of usage the choice of milling milling effect is directly related to good or bad. Generally speaking, the choice of dosage milling principles: Face milling cutter should be as much as possible when you first take a larger milling depth and width of milling, and then select the larger milling rate of as much as possible. Milling in a specific amount of choice when many factors involved, but in general, rough milling large margin when the workpiece, processing requirements low, the main consideration of the durability of cutter; Fine Milling margin is small, high precision machining, improvement in the quality processing of primary consideration;
In the engine block of the milling process, the use of machine tools as having a high stiffness, high-speed machine tools, big power, rigidity is good, so has chosen the relatively large amount of cutting.
(2) boring dosage amount of choice options under the rough finishing process varies. Rough, the selection of a larger depth of cut, finish, the selection of a smaller depth of cut. Depth of cut determined later, as cutting a large amount of use. In the cutting depth and feed rate after the selection ?=can be a reasonable tool to ensure durability under the conditions of use calculations or look-up table method to determine the cutting speed. In general, the rough, choose a lower cutting speed, finishing, the selection of a higher cutting speed.
In the engine block boring process, the selection of machine tools as having a high stiffness, high-speed machine tools, big power, good rigidity; tool for foreign advanced tools, high quality, rigidity is good, so has chosen the relatively large amount of cutting.
4.Through the engine block of the structure and process characteristics of the analysis, discusses the engine block machining process design principles and basis of the choice of cutting parameters, and U-turn at high speed milling and boring, for example, design, analysis of the engine cylinder body of high-speed milling and turnover boring process, and in the processing need to pay attention to.
