本夹具是用来完成小型轴类零件钻孔工序的。其主要特点是结构紧凑、小巧灵便.夹具结构如图所示。图中定位板是适应定位面到孔中心距为30mm的工件,若超出此范围,需把定位板卸掉,直接在机床工作台上加装定位挡块,这时夹具必须紧固在机床工作台上。压紧部分采用偏心轴机构,并通过杠杆和压块将工件压紧,这时出现了夹紧力与切削力反向的缺陷。但考虑到一般加工
The fixture is used to complete the drilling process of small shaft parts. Its main features are compact, compact and handy. Fixture structure as shown. Figure positioning plate is to adapt to the positioning surface to the hole center distance of 30mm of the workpiece, if beyond this range, remove the positioning plate, the positioning table directly on the machine table installation, then the fixture must be fastened to the machine work On the stage. Compression part of the eccentric shaft mechanism, and through the lever and the compacting of the workpiece will be pressed, then the clamping force and cutting force reverse the defects. But taking into account the general processing
