摘  要

本设计是基于JZ-S-01零件的加工工艺规程及一些工序的专用夹具设计。零件的主要加工表面是平面和孔系。一般来说，保证平面的加工精度要比保证加工精度容易。因此，本设计遵循先面后孔的原则。并将孔与平面的加工明确划分成粗加工和精加工阶段，以保证加工精度。主要加工工序是第一个支持孔定位加工出平面，然后平面和孔的位置的孔加工工艺配套系列。在后续工序中除与顶平面定位技术和加工其他孔与平面的个体的过程。利用坐标镗削加工孔。一般整个工艺的选择。专用夹具的夹具，夹紧方式多选用手动夹紧，夹紧可靠，机构不能自锁，因此生产效率高，适合于大批量、流水线上加工，能够满足设计要求。

ABSTRACT
The design of special fixture processing procedures of JZ-S-01 parts and process design based on. The main processing surface parts is the plane and hole. In general, guarantee the working accuracy of the plane is easier than to guarantee the machining accuracy. Therefore, the design follows the principle of the surface after the first hole. And the hole and the plane processing clearly divided into rough machining stage and finish machining stage, in order to ensure the machining accuracy. The main process is the first to support the hole positioning processing out of plane, and then the hole processing technology series plane and hole position. In addition to the individual process and top plane positioning technology and other processing of the hole and the plane in the follow-up working procedure. By using the coordinate boring hole. General throughout the process. Fixture fixture, clamping means more choice of manual clamping, clamping reliable, institutions can not lock, therefore the production efficiency is high, suitable for mass production line, processing, can meet the design requirements.
