Problems solved by technology

[0002] The structural connection of the existing mechanical drill bit is relatively simple. Usually, the drill bit and the drill pipe are threaded and connected without other connecting equipment. If the installation is not firm, it is easy to cause safety accidents, and its position cannot be well positioned after installation. , resulting in low verticality. If the verticality between the drill and the drill pipe is not high, the drill bit is easy to bend when drilling; at the same time, it is impossible to drill a stepped hole. For those who need to drill a stepped hole As far as drilling parts are concerned, it takes a lot of work to complete, which affects the drilling efficiency and limits the drill

Embodiment approach

[0023] As a specific embodiment of the present invention, a group of rotating wheels 121 are provided at the No. 1 groove 12; Friction between bodies 1; through this design, the present invention uses the rotating wheel 121 to change sliding into rolling, which reduces the friction between the drill body 2 and the drill body 1, slows down the loss of the drill body 1 body, and improves the use of the drill body 2 At the same time, it is convenient for the drill bit body 2 to extend and extend in the No. 1 groove 12, which improves the drilling efficiency of the drilling parts.

[0024] As a specific embodiment of the present invention, the rotating wheel 121 is made of elastic material, and a group of No. 1 chambers 122 are uniformly arranged on the rotating wheel 121; The chip hole 21 is cleaned; the present invention, through this design, on the one hand, utilizes the gas produced by the No. 1 chamber 122 on the rotating wheel 121, avoiding the waste of gas resources, thereb...

Abstract

The invention relates to a drill bit. The drill bit is characterized by comprising a drill body, at least two drill bit bodies, a positioning block and adjusting units, wherein the drill body is internally provided with a cavity, and the side wall of the drill body is provided with first grooves; the drill bit bodies are located in the first grooves, in the initial state, one ends of the two drillbit bodies are in contact with each other to form a drilling part, and the other ends of the two drill bit bodies are fixedly connected to the side walls of the first grooves through springs; a positioning block is a T-shaped block, one end of the positioning block is a tip, the positioning block is located in the cavity, and the positioning block is mounted by the adjusting units; and each adjusting unit comprises first wheels, a belt, a first rope, a clamping block and a clamping seat. According to the drill bit, the structure is simple, the positioning block naturally falls through mutualcooperation of the adjusting units and the positioning block, the tip of the positioning block impinges on a drilled part, a positioning hole is left on the drilled part, the drilling time of the drilled part is shortened, and the drilling efficiency of the drilled part is improved.

Description

technical field [0001] The invention belongs to the technical field of drill bits, and in particular relates to a drill bit. Background technique [0002] The structural connection of the existing mechanical drill bit is relatively simple. Usually, the drill bit and the drill pipe are threaded and connected without other connecting equipment. If the installation is not firm, it is easy to cause safety accidents, and its position cannot be well positioned after installation. , resulting in low verticality. If the verticality between the drill and the drill pipe is not high, the drill bit is easy to bend when drilling; at the same time, it is impossible to drill a stepped hole. For those who need to drill a stepped hole As far as drilling parts are concerned, it takes a lot of processes to complete, which affects the drilling efficiency and makes the drill bit limited. Contents of the invention [0003] In order to make up for the deficiencies of the prior art and solve the...
