我厂生产的锁接头和钻杆接头,径向尺寸为自由公差,需在接头上铣出两对夹持槽。加工时必须防止上拱和转动两种情况的产生。同时又要易于装夹.提高工效。为此,我们设计了一套多件圆柱体夹具如下图。 该夹具由固定斜块1、定位块2、动斜块3及夹具定位块4等零件组成。其工作过程为:夹紧后,动斜块3的正压力对工件产生向下分力,防止工件上拱。固定斜块1对工件以及工件间的
I plant the production of the lock and drill pipe joints, the radial size of the free tolerances, the need to be milled in the connector on the two pairs of clamping groove. Processing must prevent the arch and rotation of both situations. At the same time, it is also easy to clamp and improve work efficiency. To this end, we have designed a set of multiple cylindrical fixture as shown below. The fixture is composed of a fixed ramp 1, a positioning block 2, a movable ramp 3 and a clamp positioning block 4. The working process is: After clamping, moving the positive pressure on the inclined block 3 produces downward force on the workpiece to prevent the workpiece on the arch. Fix the ramp 1 to the workpiece and the workpiece
