我厂在车床上加工拖拉机中的调整螺杆锥形齿坯时,由于王件直径小,卡盘难以夹紧,常常发生工件打滑或打刀现象。为了解决这一问题,我们设计了一种具有双头夹持作用的弹簧夹头(如附图所示)。其作用原理如下:拉杆1在气缸的作用下带动滑套2向后移动。因滑套内做成一倒银,与弹簧夹头5的后端外锥面相配合,使弹簧夹头一同后移。由于弹簧夹头的
I plant in the lathe processing tractor screw conical tooth blanks, the king of small diameter, the chuck is difficult to clamp, often occurs skidding or playing the phenomenon of the workpiece. In order to solve this problem, we designed a collet chuck with double-headed clamping (as shown in the figure). The principle of action is as follows: The rod 1 drives the sliding sleeve 2 to move backwards under the action of the cylinder. Due to the sliding sleeve made of an inverted silver, and the rear end of the collet 5 matching the outer cone, so that the collet together after the move. Due to the collet chuck
