在组合机床加工中,经常遇到各种固定套、导套之类的薄壁套加工问题。尤其是精磨时,常因装卡变形,造成工件成批报废,给工作带来很大困难。我们制造了一种简单磨内孔的夹具(见图),它只有4种零件组成,解决了装夹变形问题。夹具体1装夹在磨床卡盘上,定位预紧螺栓2只能作轻微定位用,不能起夹紧作用,调好后要用背帽固 In the combination of machine tool processing, often encounter a variety of fixed sets, such as thin-walled sets of sleeve processing problems. Especially when grinding, often due to loading card deformation, resulting in batch scrapped work, to work a great difficulty. We made a fixture with a simple bore (see photo), which consists of only four parts to solve the problem of clip deformation. Clamp 1 mounted on the grinder chuck, pre-positioning bolt 2 can only be used for slight positioning, can not play the role of clamping, adjusting the back cap should be used after the solid
