拨叉零件的加工工艺规程编制及专用夹具设计-钻孔夹具（有CAD图纸）.pdf

: I ABSTRACT This design is to dials forks the components the processing craft and the jig design, its components are the forging, has the volume to be small, components complex characteristic,Because the surface is easier than the hole to process, when formulation technological process, first the machined surface, then processes other take the surface as the datum,In which various working procedures jig all uses the unit clamp, special regarding processes the big end of hole, the trough and drills the capitellum hole incline eyelet in the working procedure, Chooses locate mode which two sells at the same time, and operates the simple manual clamp way clamp, its organization design is simple, the convenience also can satisfy the request.
