These shockproof mechanisms generally use a method of applying pressure around the tool to reduce vibration. However, this design does not consider shockproof treatment of the tool tip, so in actual application, this shockproof method often fails to achieve ideal shockproof effect, affecting the stability and processing accuracy of the tool during use. This situation shows that existing tool shockproof technology still needs to be improved to improve the shockproof performance of the tool during processing. SUMMARY

[0012] Compared with the prior art, the present invention provides a tool vibration-proof mechanism for parts processing, which has the following beneficial effects:

[0013] 1. The utility model provides a locking bolt and a damping spring. When installing the tool, the drill bit is fixed in the tool slot by the three-claw clamp, and the locking bolt is screwed into the tool slot. The locking bolt squeezes the top plate and the top block toward the lower end until the locking bolt is locked to the limit. At this time, the downward push force of the damping spring and the telescopic rod structure plays a shock-proof role on the upper surface of the drill bit through the shock-proof block, thereby achieving the stability and shock-proof effect of the tool installation, effectively improving the stability and processing accuracy of the tool during use, and effectively avoiding the problem that the traditional design does not take into account the shock-proof treatment of the tool end. Therefore, in actual application, this shock-proof method often cannot achieve the ideal shock-proof effect, resulting in the problem that the stability and processing accuracy of the tool during use are affected;
