Description

Technical Field

[0001] The utility model relates to the technical field of drill bits, in particular to a novel chamfering drill bit. Background Art

[0002] Chamfering drill is a special type of drill, mainly used for chamfering the surface of materials, that is, removing the edge or corner of the material to make the surface smoother and neater. This drill usually has a small cutting radius, which can effectively perform chamfering without damaging the material itself.

[0003] A new chamfer drill with announcement number CN 213317897 U. The chamfering tool can completely replace the traditional chamfering drill. The setting of the milling edge replaces the chamfering edge of the traditional chamfering drill, which reduces the tool cost by 30% and solves the depth limitation problem of the traditional chamfering drill. The drilling depth of the new chamfering tool is easy to control. After drilling is completed, milling out the chamfer is convenient and quick, reducing the types of tools.

[0029] Furthermore, the left side of the first spring 38 is fixedly connected to the right side of the sliding plate 36, and the right side of the first spring 38 is fixedly connected to the inside of the fixed disk 31. Through the arrangement of the first spring 38, when the rotating disk 301 does not squeeze the extrusion block 39, the first spring 38 can drive the sliding plate 36 to move through the first telescopic rod 37, so that the sliding plate 36 drives the extrusion block 39 to return to its original position.

[0035] Furthermore, a fixing hole corresponding to the size of the drill body 1 is opened inside the dust cover 41, and the size of the fixing hole is larger than the size of the drill body 1. Through the opening of the fixing hole, the dust cover 41 is not easy to rotate with the drill body 1 during the rotation of the drill body 1.

[0036] In actual operation, when the device is used, when the position of the adjusting piece 32 needs to be adjusted, the rotating disk 301 is rotated so that the rotating disk 301 can push the extrusion block 39, so that the extrusion block 39 can drive the connecting plate 35 to move through the sliding plate 36, so that the connecting plate 35 can drive the adjusting piece 32 to move, so that the position of the adjusting piece 32 can be adjusted, so that the drill body 1 can be suitable for clamping with different clamps. When the adjusting piece 32 needs to be retracted, the rotating disk 301 is rotated in the opposite direction so that the first spring 38 can drive the first telescopic rod 37 to retract, so that the sliding plate 36 can drive the adjusting piece 32 to move through the connecting plate 35, so that the adjusting piece 32 can return to its original position.

[0037] When the drill body 1 is in use, the drill body 1 moves downward so that the bottom of the dust cover 41 can contact the surface of the object to be processed, so that the dust cover 41 can block the dust generated when the drill body 1 is processed.
