尾座體加工工藝及夾具設(shè)計(jì)
摘 要
摘 要
本課題主要是設(shè)計(jì)某機(jī)床尾座體的加工工藝及夾具的設(shè)計(jì),在設(shè)計(jì)中采用先設(shè)計(jì)該尾座體的加工工藝在根據(jù)加工工藝來(lái)選取夾具的設(shè)計(jì)的方案和夾具的具體設(shè)計(jì);而設(shè)計(jì)的重點(diǎn)是夾具的設(shè)計(jì)。由于工件的孔17和14都要以底面做為基準(zhǔn)加工,故首先得做出底面的加工夾具。由于孔17的精度要求高,和定位尺寸誤差小,為保證孔的位置和加工準(zhǔn)確性我們一定在加工底面的時(shí)間通過(guò)畫(huà)線找出底面的加工余量。這樣就可以更好的保證孔17的位置和加工精度!加工孔14的夾具其實(shí)就是在加工底面夾具的基礎(chǔ)上加了一個(gè)45度斜度板。加工孔17的時(shí)間為保證相對(duì)于A和B面的平行度我們就得要準(zhǔn)確的設(shè)計(jì)出以A和B面定為的夾具!還考慮到工件的圓度和圓柱度的誤差小,我們?cè)O(shè)計(jì)的夾具就具有對(duì)孔17的夾具定位準(zhǔn)確,和加工時(shí)間的震動(dòng)小,那就得在孔17的附近找個(gè)定位加緊點(diǎn)!

ABSTRACT
ABSTRACT
This topic is mainly design that designs the tail a body of some tool machine to process the craft and tongses, adopting to design first in the design a body of that tail processes the craft at according to process the craft to select by examinations the tongs of the project of the design and concrete design of the tongs;But the point of design is the design of the tongs.Because the bore of the work piece 17 and 14 all want to face to be used as the basis to process with the bottom, past have to do a bottom to face first of process the tongs.Because bore 17 of accuracy have high request, and position the size error margin small, for guarantee the position of the bore and process the accuracy we certainly at process the bottom to face of time pass to draw the line to find out the bottom to face of process the amount of remaining.Thus can with better assurance bore 17 of position and process the accuracy!Process the bore 14 of tongs was in processing the foundation that the bottom faces the furniture to add one 45 degrees of gradient plank in fact.Process the bore 17 of time is opposite for assurance to run parallel with B face of in the A we have to design accurately with the AN and B faces to settle for of tongs!Return in consideration of a degree of the work piece and the error margin of the cylinder degrees are small, the furniture that we design have to the bore 17 of tongs fixed position is accurate, and process the vibration of time small, that have to in the bore 17 of neighborhood seek a fixed position to step up the point!
