本刀具(苏联发明证书号№704727)的特点是杠杆的上臂6带有曲线凸台4,凸台4与刀片主刀刃1方向的孔壁接触。凸台及其相对部分的曲率应使刀片能在杠杆上臂上自由装卸(当上臂未固定时)。刀片的紧固是通过压紧螺钉10作用在杠杆另一臂9上的办法来进行的。当杠杆绕点8旋转时,便将刀片移动靠在糟壁2上,同时杠杆下降并以凸台4将刀片压在刀杆7的支承面5上。这种紧固方法保证刀片和刀杆的支承面能紧密贴合,因此可以提高粗加工工序的可靠性,在间断切削和机床一夹具
The tool (the Soviet Union invention certificate number № 704727) is characterized by a lever arm 6 with a curved curve boss 4, the boss 4 and the main blade edge blade 1 wall contact. The curvature of the bosses and their counterparts should allow the blade to be freely dismounted (when the upper arm is not secured) on the lever arm. The fastening of the blade is carried out by means of the compression screw 10 acting on the other arm 9 of the lever. As the lever rotates about the point 8, the blade is moved against the bad wall 2 while the lever is lowered and the blade 4 is pressed against the bearing surface 5 of the holder 7 with the boss 4. This fastening method to ensure that the blade and the arbor support surface can be closely fit, so you can increase the reliability of the roughing process, cutting and cutting a machine tool
