X225铣床传动箱体加工工艺及铣床夹具设计 摘要 本设计是箱体零件的加工工艺规程及一些工序的专用夹具设计。箱体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整个加工过程均选用组合机床。夹具选用专用夹具，夹紧方式选用气动夹紧，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。X225 Milling and Drilling Machine Gear Box Fixture Design Process Abstract Machine Tool fixture is a fixture in will be fixed to the machine, can be processed pieces of the machine tool and the right to maintain the relative position and to overcome the impact of cutting force.So that the processing carried out smoothly. The design is about Milling transimiddion box after drilling holes 12fixture design and peocessing technology.The design and manufacture of fix ture is a very important work in the manufacture process of Milling machine parts,The quality of fixture design and manufacture has a major effect on the machining efficiency and the quality of parts. The cycle of fixture design and manufacture decides the whole production preparation cycle of Milling machine parts.And mechanical stationary machine is the important tool that is used to process the accessories in the process of making the accessories, and the design affects directly the accurate of the accessories and the price.Thus it also affects the ability and the rate of ability to price.So rapid that In our country , mechanical stationary machine has a very wide prospect.By the accessories and mechanical stationary machine has a great big space for development. Based on the analysis of the processing technic and configuration feature of the cabinet on the screw hole, the author gives a design of drilling jig. This paper puts great emphasis on jig’s working process positioning And the rough cushion over determination projectclamping means position error and verification of clamping force.Practice has proved that the jig is convenient to operate and has a high production efficiency. Mechanical fixture in the structure should be toward the direction of the simple, easy-to-use, h
