铣削电度表转盘轴、蜗杆等有色金属小零件槽时,因切削力不大,可采用弹力压紧夹具(附图)。其工作原理如下:工件5放在左右夹具体3和右夹具体6之间的孔内,靠弹簧9的弹力压紧,弹力大小由螺母10调节。螺杆8固定在左夹具体3上,右夹具体6套在螺杆8上。进刀时在弹力作用下,左右夹具体和工件结合成一体。用手向右扳动杠杆机构11,夹具体连同
Milling table, turntable shaft, worm and other non-ferrous metal parts slot, due to the cutting force is not big, can use elastic compression fixture (with photos). Its working principle is as follows: The workpiece 5 is placed in the hole between the left and right clamp body 3 and the right clamp body 6, and is pressed by the elastic force of the spring 9, and the elastic force is adjusted by the nut 10. The screw 8 is fixed on the left clamping body 3, and the right clamping body 6 is sleeved on the screw 8. Feeding the role of the elastic force, the left and right clamping body and the workpiece into one. Pull the lever mechanism 11 to the right by hand, with the clamp body together
