Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides a novel chamfer drill bit, including drilling rod 1, the tip of drilling rod 1 has conical drill point 4, there is drill point 4 to the other end of drilling rod 1, the diameter of drilling rod 1 is the same, twice chip groove 2 has on the drilling rod 1, and chip groove 2 extends to drill point 4, drill point 4 is the cone shape, form smear metal sword 3 between chip groove 2 and the drilling rod 1, seted up on the drill point 4 and milled blade 5, the installation pot head of drilling rod 1 is equipped with mounting 6, and jack 7 has been seted up on mounting 6 and the drilling rod 1, the inside of jack 7 is inserted and is equipped with pin 8.
Specifically, as shown in fig. 1, the milling cutting edges 5 are provided on the drill point 4, the milling cutting edges 5 are connected with the cutting edges 3, the milling cutting edges 5 are provided with a pair of the drill point 4 and are arranged in a centrosymmetric manner, after drilling is completed, the drill bit is taken out, and chamfers are milled at the hole openings by using the added milling cutting edges 5.
Specifically, as shown in fig. 1, the cutting edge 3 and the chip groove 2 are of a twist-like structure, and the cutting edge 3 is a cutting edge formed between the chip groove 2 and the drill rod 1.
Specifically, as shown in fig. 1, the surface of the chip groove 2 is a smooth curved surface, one end of the chip groove 2 is connected with the drill tip 4, the other end of the chip groove extends to the middle position of the drill rod 1, the chip groove 2 rotates the drill tip 4 to cut off the broken slag and discharge the broken slag, the chip cutting edge 3 rotates to remove burrs from the hole wall, the cut broken slag also enters the chip groove 2, and the chip groove 2 rotates to discharge the broken slag.
