我厂在加工6135燃油泵时,使用图1所示钻孔、攻丝卡头,结构简单,制作方便,缩短更换时间。当需要按装钻头时,提起卡套3,滚珠便流进卡套里,把卡套放下,滚珠便被压进件2的圆窝内,件4便带动件2旋转。当需要攻丝时,换上图2攻丝部分,便可进行攻丝。图2中弹簧7的压力是靠件8来调节的,件7压在摩擦片5上,件4中间方孔套在传动轴2的方头上。当切削力大于摩擦力所能传递的力矩时,摩
I plant processing 6135 fuel pump, use the drilling shown in Figure 1, tapping chuck, simple structure, easy production, shorten the replacement time. When you need to press the drill bit, lift the sleeve 3, the ball will flow into the sleeve, the card set down, the ball will be pressed into the round nest 2, 4 will drive 2 rotation. When you need tapping, put the tapping part in Figure 2, you can tap. 2, the pressure of the spring 7 is adjusted by the member 8, the member 7 is pressed against the friction plate 5, and the middle square hole of the member 4 is sleeved on the square head of the transmission shaft 2. When the cutting force is greater than the friction can transmit the torque, friction
