重型机夹可转位车是在大型卧车、立式车床使用的一种刀片立式装夹的刀具。由于刀片尺寸形状所限,故刀片夹紧的方式大致分为两种形式:一种以孔定位用楔块压紧;另一种则以长度方向的一个端面定位,用压孔方式压紧(偏心、直角杠杆、勾销、杠销、拉垫式均为压孔压紧方式)。由于重型刀具的切削条件较差,切削力是很大的,上述两种压紧形式程度不同地存在着夹紧力不足、或定位销易弯曲变型等
Heavy machine folder can be indexable car in the large sleeper, vertical lathe blade used a vertical clamping tool. Due to the limited size and shape of the blade, the clamping of the blade can be roughly divided into two forms: one is pressed by a wedge for hole positioning; the other is positioned by one end in the length direction and pressed by a pressure hole Eccentric, right-angle lever, write-off, lever pin, pull pad are pressed hole compression method). Due to the heavy cutting tool cutting conditions are poor, the cutting force is very large, the two forms of compression there is a different degree of clamping force is not enough, or flexible pin deformation
