Abstract
This paper analyses the function and technicality of the connecting rod, and introduces in detail the formulation of the connecting rod processing process: 1. the selection of the positioning datum of the connecting rod; 2. the formulation of the processing route of the connecting rod; 3. the selection of the processing equipment and the connecting rod processing equipment for the connecting rod; 4. the determination of the cutting parameters of the connecting rod and the basicworking hours of the connecting rod processing. Then it introduces the design and calculation of the connecting rod processing fixture, including the analysis of the processing mode of the connecting rod in this process. Then it determines the processing type of the fixture, determines the processing scheme after leasing and determines the clamping scheme by selecting the connecting rod positioning elements, and determines the special fixture for the final connecting rod design of the tool setting device.
Keywords: lever, processing technology, special fixture
