摘要

本次設(shè)計(jì)的是減速器箱體的加工工藝以及加工Φ120外圓的夾具設(shè)計(jì)。減速器箱體零件是減速器的基礎(chǔ)件，它將減速器的零件按一定的相互位置關(guān)系裝配成一個(gè)整體，并按預(yù)定傳動(dòng)關(guān)系協(xié)調(diào)其運(yùn)動(dòng)。因此，箱體的加工質(zhì)量不僅影響其裝配精度及運(yùn)動(dòng)精度，而且影響到機(jī)器的工作精度、使用性能和壽命。
夾具設(shè)計(jì)是針對(duì)Φ120外圓的專用夾具，考慮到零件的數(shù)量比較大，屬于大規(guī)模生產(chǎn)，所以生產(chǎn)效率是非常重要的，所以此設(shè)計(jì)不采用以往手動(dòng)方式的夾具，采用技術(shù)比較先進(jìn)的氣動(dòng)作為夾緊力來(lái)源。零件并沒(méi)有過(guò)高的技術(shù)要求，所以采用一個(gè)銷定位，平面支承，配合夾具的左右同時(shí)夾緊便可以滿足要求。

關(guān)鍵詞：工藝設(shè)計(jì)、基準(zhǔn)、切削用量、定位基準(zhǔn)、定位誤差。



ABSTRACT

The design of the box is reducer processing and processing Φ 120 of the cylindrical fixture design. Reducer box parts of the foundation pieces of reducer, It reducer by certain parts of the positional relationship between a general assembly, together with a planned drive to coordinate its relations campaign. Therefore, the processing box is not only affect their quality of assembly accuracy and precision of movement, but also affects the accuracy of the machine, performance and life.
Fixture Design against Φ 120 outside of the special fixture, taking into account the number of parts is comparatively big, large-scale production, Therefore, productivity is very important, so do not use this design manually to the previous fixture. using technology more advanced aerodynamic as a source of clamping force. Parts and not too high technical requirements and the use of a marketing positioning, supporting plane, with the fixture clamping around the same time they meet requirements.

Key words : technological design,standard, cutting consumption, positioning benchmark positioning error.
