I II ABSTRACT The topic of this graduation design is a tractor reverse shift fork crossings side milling fixture design. I mainly need to complete the processing technology and a special machine tool fixture design. In order to ensure machining precision at the same time, save cost and shorten the processing cycle and improve the processing efficiency, then a good process arrangement and special fixture design is essential for the. In the process of the arrangement not only to consider the reasonable processing requirements but also taking into account the safety of the operator and processing machinery. At the same time, the design of the fixture should take into account the use of safety and economy as well as the ease of installation and disassembly. To design a good process for the arrangement of the route then must go through a detai
