Abstract
The special fixture plays an important role in the present machining process,which realizes the positioning and clamping of theworkpiece. The research object of this design is CA10B Jiefang car rear leaf spring lifting lug. The main research contents include the design of machining process and fixture of drilling machine
CA10B Jiefang car is one of the typical cars. The rear leaf spring lifting lug provides support for the positioning andworking of the spring and main parts, and escorts the normalwork of the car. Before the design of processing technology, the function of parts and the analysis of part drawing are completed. The production type, manufacturing mode and machining allowance of parts are determined, and the blank drawing is drawn. Design the processing route, calculate the cutting parameters involved in the process card. Finally, the process card and process card are improved.
The design contents of the parts are: determine the positioning scheme of the parts(meet the 6-point positioning principle); select the clamping device and clamping element; design and determine the clamp; design the tool setting device(drill sleeve) to ensure the machining accuracy of the parts; calculate the clamping force and cutting force of the parts in the clamping process. Finally, complete the fixture assembly drawing of special fixture and all non-standard part drawing.
