套管加工工艺及磨端面夹具设计
摘要
本设计是基于套管零件的加工工艺规程及一些工序的专用夹具设计。套管零件的主要加工表面是平面及孔系。一般来说，保证平面的加工精度要比保证孔系的加工精度容易。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孔系加工精度。基准选择以套管的底面作为粗基准，以端面与孔作为精基准。主要加工工序安排是先以支承孔系定位加工出端面孔系定位加工出工艺孔。在后续工序中除个别工序外均用顶平面和工艺孔定位加工其他孔系与平面。整个加工过程均选用专用机床。夹具选用专用夹具，夹紧方式多选用手动夹紧，夹紧可靠，机构可以不必自锁，因此生产效率较高，适用于大批量、流水线上加工，能够满足设计要求。

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. Planewith 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 topwith 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. Thewhole process of processing machine combinationswere 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.
