附图所示的工具可安装在车床、钻床等机床上,用以倒工件的内外角,以及去毛刺.它是由刀夹本体1、推杆2、钢球4、带切削刀片5的套筒7等元件组成。推杆的前端作有倒内角的切削刃6,刀片5是用来倒工件外角用的。推杆和套筒可相对于刀夹本体作轴向移动,因此在工作过程中,工具对被加工工件的尺寸能实现自动调整。螺钉3和8可防止推杆和套筒与本体1之间产生相对转动。该工具按以下方式工作。当工具作走刀运动时,如切削刃6先接触到工件的内表面,此时通过钢球4
The tool shown in the drawings can be installed on a machine tool such as a lathe, a drilling machine and the like to down-fill the inside and outside corners of the workpiece and deburr it by the holder body 1, the push rod 2, the ball 4, the sleeve with the cutting insert 5 Cylinder 7 and other components. The front end of the push rod is provided with an inner corner cutting edge 6, and the blade 5 is used to down-tilt the outer corner of the workpiece. The push rod and the sleeve are axially movable with respect to the body of the holder so that the tool automatically adjusts the size of the workpiece to be machined during operation. The screws 3 and 8 prevent relative rotation between the push rod and the sleeve and the body 1. The tool works as follows. When the tool for the move, such as the cutting edge 6 first contact with the inner surface of the workpiece, this time through the ball 4
