缸體的加工工藝及夾具設(shè)計【銑凸臺面(銑上小端面)、鉆底面4XΦ9孔兩套夾具】
摘 要
本設(shè)計是基于缸體零件的加工工藝規(guī)程及一些工序的專用夾具設(shè)計。缸體零件的主要加工表面是平面及孔系。一般來說,保證平面的加工精度要比保證孔系的加工精度容易。因此,本設(shè)計遵循先面后孔的原則。并將孔與平面的加工明確劃分成粗加工和精加工階段以保證孔系加工精度。基準(zhǔn)選擇以缸體的輸入軸和輸出軸的支承孔作為粗基準(zhǔn),以底面與兩個工藝孔作為精基準(zhǔn)。主要加工工序安排是先以支承孔系定位加工出頂平面,再以頂平面與支承孔系定位加工出工藝孔。在后續(xù)工序中除個別工序外均用頂平面和工藝孔定位加工其他孔系與平面。支承孔系的加工采用的是坐標(biāo)法鏜孔。整個加工過程均選用組合機(jī)床。夾具選用專用夾具,,機(jī)構(gòu)可以不必自鎖,因此生產(chǎn)效率較高,適用于大批量、流水線上加工,能夠滿足設(shè)計要求。

ABSTRACT
The design is based on the body parts of the processing order of the processes and some special fixture design. Body parts of the main plane of the surface and pore system. In general, the plane guarantee processing precision than that of holes machining precision easy. Therefore, this design follows the surface after the first hole principle. Plane with holes and the processing clearly divided into roughing and finishing stages of holes to ensure machining accuracy. Datum selection box input shaft and the output shaft of the supporting hole as a rough benchmark, with top with two holes as a precision technology reference. Main processes arrangements to support holes for positioning and processing the top plane, and then the top plane and the supporting hole location hole processing technology. In addition to the follow-up processes individual processes are made of the top plane and technological hole location hole and plane processing. Supported hole processing using the method of coordinate boring. The whole process of processing machine combinations were selected. Selection of special fixture fixture, clamping means more choice of pneumatic clamping, clamping reliable, institutions can not be locked, so the production efficiency is high, suitable for large batch, line processing, can meet the design requirements.
