Abstract:By designing a simple jig, the problems in processing were solved, improving the processing efficiency. Pipe bending part of the component and fixture holes were formed holeshaft location, hole in the part and the cutting edge pin on the fixture were formed pin hole positioning.Through the fixture,the parts rotary center was coincided with the lathe rotary center,to realize the cutting condition. The fixture has low manufacturing cost and simple operation, the machining quality is ensured effectively.
