As the size of the parts changes, more and more clamps are eliminated. Therefore, it is necessary to design a set of special fixtures. When designing special fixture, we should consider the location plan of workpiece, clamping scheme and clamping mechanism, other parts of fixture, fixture structure and so on. The main research content of this subject is the analysis of the machining process of engine fork and the design of milling fixture. Based on the analysis of the structure of the parts, the selection of the positioning datum, the design of the fixture, the selection of various tool parameters and the selection of the cutting parameters are carried out according to the key points and difficulties in the machining of the parts. In the arrangement of the process, according to the processing requirements, the need for rough finishing. In addition, cutting parameters, working hours, filling out process cards and process cards are also determined. A special fixture for milling 16mm slot is designed. Key words: Automobile fork, processing technology, 16mm slot, milling machine, special fixture I II ABSTRACT III 1 1.1 1 1.2 1 1.3 1 1.4 2 3 2.1 3 2.2 桢 3 2.2.1 3 2.2.2 4 2.2.3 4 5 3.1 5 3.1.1 5 3.1.2 5 3.2 6 3.3 7 3.4 7 3.5 8 3.6 估 9 16mm 19 4.1 19 4.1.1 19 4.1.2 19 4.1.3 1
