In the jig design process, mainly locates by V shape block and the support plate, depends on the straight clamp and the spring clamps, drills turns diameter two to be supposed to use long trades quickly drills the wrap, when drills turns the diameter incline hole uses the plane incline the jig body, when drills turns the diameter incline hole uses is the horizontal-type drilling machine, when face milling 2 V shape blocks and the milling cutter cannot interfere ,therefore V shape block altitude must reduce, the jig design must be convenient, be simple. Key words crank, processing craft, jig design. PAGE 4 1 淢涨棬缼 2 2.1 3L10/8 2.2 3L-10/8棬.: 2.2.1?95mm : ?95 mm,?8,?95 mm0.01 mm 2.2.2 棺11024 mm?15 m
