在车床上加工工件的光孔或螺纹孔时,经常是使用与被加工孔要求相同的铰刀或丝锥来完成的。刃具的装夹一般是用手动铰板或活络板头来承受切削力矩,并由车床尾座顶尖支承、定心和实现进刀运动。上述装夹方法工效较低,工作不稳定,往往由于切削力不均匀而导致铰刀或丝锥的折断。我们设计使用了附图所示的车用攻铰夹头来装夹刃具,能克服上述缺点,确保加工质量和提高工效。装夹过程如下:顶尖1装入车床尾座锥孔中,60°顶尖顶住刃具使之定心,蝶形螺杆3使两个夹爪4和5夹住刃具头部方笋,装
When machining a hole or tapped hole in a lathe, it is often done using the same reamer or tap as the hole being machined. Cutting tool clamping is generally manual hinge plate or board head to withstand cutting torque, and the top of the lathe tailstock support, centering and to achieve feed movement. The above clamping method has low efficiency and unstable work, and often causes the reamer or the tap to break due to the uneven cutting force. We designed the use of the car shown in the picture attached to the tapping chuck chuck to overcome these shortcomings to ensure processing quality and improve work efficiency. The clamping process is as follows: the top 1 is loaded into the taper hole of the tailstock of the lathe, the top of the 60 ° pinches the cutting tool to be centered, the butterfly screw 3 makes the two clamping jaws 4 and 5 clamp the head of the cutting tool and shoots
