一种永磁可调式自动快速前顶尖A permanent magnet adjustable automatic fast front center

技术领域technical field

本实用新型涉及车床装夹设备技术领域，具体为一种永磁可调式自动快速前顶尖。The utility model relates to the technical field of lathe clamping equipment, in particular to a permanent magnet adjustable automatic fast front tip.

背景技术Background technique

在传统的机床加工轴类产品中，特别是轴类两头是由二个中心孔定心，变后由鸡心夹具固定在轴的前端，驱动轴类零件转动，保证轴类零件在车床，磨床的切削工艺要求。In the traditional machine tool processing shaft products, especially the two ends of the shaft are centered by two center holes, and then fixed on the front end of the shaft by a core clamp after the change, and the shaft parts are driven to rotate to ensure that the shaft parts are used in the lathe and grinder. Cutting process Require.

现有技术的不足：Disadvantages of the existing technology:

用鸡心夹具带动轴类零件的缺点在于不能对所需加工的轴类零件一次性加工完成，因为鸡心夹具所固定的轴端，刀具或磨床砂轮无法通过，因此必须二次加工才能完成固定鸡心.夹具的轴端，特别是二次加工要关闭机床电机后，工件才能拿下重新二次加工，不仅浪费加工时间，影响工效，而且电机的频繁关开耗电能量大，也直接造成电机的损坏，外齿前顶尖虽然能解决一次性地轴类零件加工完成，也能不停车的情况下安装零件，但是高限于加工直径在中30/以下，而且依靠齿面嵌入轴类平面驱动轴零件转动时力量有时达不到要求，在刀具切削轴类零件产生较大的切削力时，轴件有时转动打滑现象。The disadvantage of driving the shaft parts with the chicken heart clamp is that the shaft parts to be processed cannot be processed at one time, because the shaft end fixed by the chicken heart clamp, the tool or the grinding wheel of the grinder cannot pass through, so it must be processed twice to complete the fixed chicken heart. The shaft end of the fixture, especially after the machine tool motor is turned off for secondary processing, can the workpiece be taken off for secondary processing, which not only wastes processing time and affects work efficiency, but also consumes a lot of power when the motor is frequently turned on and off, which directly causes damage to the motor. , Although the front center of the external tooth can solve the one-time processing of shaft parts, and can also install the parts without stopping, but the height is limited to the processing diameter of 30 / below, and the tooth surface is embedded in the shaft plane to drive the shaft parts when rotating. The force sometimes does not meet the requirements. When the tool cuts shaft parts with a large cutting force, the shaft sometimes rotates and slips.
