Due to design limitations, traditional drill clamping devices are usually only suitable for drills of specific sizes, and the operation is cumbersome and requires manual adjustment of the clamping force, which not only reduces the processing efficiency, but also easily leads to damage to the drill or unstable clamping. At the same time, during the high-speed drilling process, the high temperature and large amount of cutting debris generated may affect the processing accuracy, shorten the tool life, and even cause safety hazards if they are not handled in time.
[0003] Most of the clamping devices in the prior art lack automatic adjustment and intelligent control functions. For drill bits of different sizes, operators need to frequently change the clamps or make manual adjustments, which not only increases the complexity of operation, but also increases the risk of human error. In addition, poor heat dissipation and lubrication can cause the drill bit to overheat, thus affecting the processing quality and efficiency. In response to these problems, the development of a clamping device that can automatically adjust the clamping, has a cooling function, and can effectively clean up debris has become an important technical demand in the field of mechanical processing.
