齒輪軸加工工藝規(guī)程設(shè)計(jì)
摘要
本文是對(duì)齒輪軸零件加工應(yīng)用及加工的工藝性分析，主要包括對(duì)零件圖的分析、毛坯的選擇、零件的裝夾、工藝路線的制訂、刀具的選擇、切削用量的確定、加工工藝文件的填寫。選擇正確的加工方法，設(shè)計(jì)合理的加工工藝過程。此外還對(duì)支架零件的兩道工序的加工設(shè)計(jì)了專用夾具.
機(jī)床夾具的種類很多，其中，使用范圍最廣的通用夾具，規(guī)格尺寸多已標(biāo)準(zhǔn)化，并且有專業(yè)的工廠進(jìn)行生產(chǎn)。而廣泛用于批量生產(chǎn)，專為齒輪軸工件加工工序服務(wù)的專用夾具，則需要各制造廠根據(jù)工件加工工藝自行設(shè)計(jì)制造。本論文夾具設(shè)計(jì)的主要內(nèi)容是設(shè)計(jì)專用夾具。

Abstract
This paper is the analysis of the gear shaft parts processing technology application and processing, including the parts diagram analysis, the choice of blank, parts of the fixture, the formulation of the process route, tool selection, cutting, processing documents. Choose the correct processing methods, design the reasonable process. In addition, processing of two processes to support part of the design of special fixture.
Many kinds of the machine tools fixture, the fixture, the most widely used, the size has been standardized, and there is a professional factory production. But widely uses in the volume production, specially the special fixture for gear shaft workpiece machining processes and services, to the factory according to the workpiece machining process to design and manufacture. The main content of this thesis is to design of fixture design fixture.
Keywords gear shaft, machining process, fixture, design
