In the figure: the drilling tool comprises a pushing back plate 1, a first bolt hole 1-1, a counter bore 1-2, a pushing front plate 2, a second bolt hole 2-1, a pushing plate 2-2, pushing teeth 2-4, a drill point placing plate 3, a V-shaped groove 3-1, a groove body 3-2 and a connecting hole 3-3.

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 in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-13, a micro-drill efficient cutting device comprises a driving device, a sliding guide rail and a sliding block, wherein the sliding block is connected with a pushing rear plate 1, a first bolt hole 1-1 is formed in the front side wall of the pushing rear plate 1, the first bolt hole 1-1 is matched with a second bolt hole 2-1 in the front side wall of a pushing front plate 2, a pushing plate 2-2 is connected to the front end of the pushing front plate 2, and a plurality of pushing teeth 2-4 are arranged on the pushing plate 2-2; the pushing teeth 2-4 are matched with the V-shaped grooves 3-1 on the drill point placing plate 3, and the front end part of the drill point placing plate 3 is provided with a groove body 3-2. The propulsion back plate 1 is provided with a counter bore 1-2 which is convenient to be connected with a sliding block.

The utility model discloses a process as follows: the drill point placing plate 3 is fixed on a bracket of the cutting machine, wherein the groove body 3-2 is positioned under the grinding wheel and is used for the work of the grinding wheel. The pushing back plate 1 is connected with the sliding block, the sliding block is driven to move along the sliding rail through a cylinder or a chain and the like, and the direction of the sliding rail is parallel to the direction of the V-shaped groove 3-1.
