目前我国广泛使用的小型合虎钳,钳体为固定式,不能随意变换工件的角度和位置,于是出现加工者不得不变换各种姿势绕着虎钳转的现象。我们制作的这台小型活动虎钳是参考国外同类型产品设计出来的,适合于加工表面多而施力不大的场合,具有以下优点:1.结构简单:钳口移动导轨采用两根圆轴代替通常的燕尾槽导轨,钳体支杆与台座采用球面副联接。 At present, the widely used small clamp vise in China is fixed and can not change the angle and position of the workpiece at will. As a result, the processors have to change the posture of the vise turning around. The small vise we made is designed with reference to the same type of foreign products and is suitable for occasions with many surfaces but with little force. It has the following advantages: 1. Simple structure: The jaws move with two circular shafts Instead of the usual dovetail rail, the clamp body and the pedestal are connected by a spherical pair.
