Abstract
This design is about CA6140 lathe handle seat, and the content includes the components analysis, the formulation of process route, and the process planning design, fixture design to a process and process card to the process, the assembly drawing and fixture base component drawing, and so on.
We first analyze the structure, the use and the technical process of the handle in detail, and then we determine a reasonable processing scheme. And the processing plan requires that it should be simple, and it also can guarantee the processing quality. Because the surface precision demand of a handle is higher, so we should do rough milling first and then half-fine milling in processing of some major plane, when we processing some holes, we should drilling and reaming first, and then fine-hinge in the process. Because the processing quality of a handle will directly influence the performance and the long service life, so every procedure must be achieved its processing requirements.
Otherwise, as we know the production type of this design is mass production, in order to improve the productivity of labor, to reduce the labor intensity, to guarantee the machining quality, we need to design special fixture, and in this design, we should design a fixture which it can help us processing a φ14H7mm hole in CA6140 lathe handle.
Key words: CA6140 lathe handle seat; Process planning; Special fixture design; Fixture assembly drawing
