Complete equipment special for preparing high-hardness glass drill bit

Abstract

The invention discloses complete equipment special for preparing a high-hardness glass drill bit. The complete equipment comprises a handle clamping mechanism, a first sliding rail, a first push rod, a head clamping mechanism, a second sliding rail, a second push rod, a rotation driving mechanism, a supporting frame, a grinding mechanism and lifting push rods; the handle clamping mechanism is arranged on a working table in a sliding mode through the first sliding rail; the first push rod is arranged on one side of the handle clamping mechanism; the head clamping mechanism is arranged on the working table in a sliding mode through the second sliding rail; the second push rod is arranged on one side of the head clamping mechanism; the rotation driving mechanism is arranged on one side of the head clamping mechanism and drives the head clamping mechanism to rotate; the supporting frame is arranged at the middle end of the working table; the grinding mechanism is arranged at the bottom end of the supporting frame; and the lifting push rods are arranged on the two sides of the inner top face of the supporting frame. The complete equipment can grind a plurality of glass drills at the same time, the process preparation efficiency is high, the clamping and fastening performance on the single glass drill is high, and the grinding effect is good.

Description

technical field [0001] The invention relates to the field of drill bit preparation, in particular to a complete set of special equipment for preparing high-hardness glass drill bits. Background technique [0002] The structure of the drill bit is various, and the structure of the selected drill bit is also different according to the drilling medium. For the drilling process on the glass surface, because the glass surface has a strong smoothness, and the glass has a strong brittleness, when selecting a drill for the drilling process, it is necessary to use a suitable drill structure and a suitable drill Feed and feed forces to maintain the integrity of the overall structure of the glass. Correspondingly, in the structural form of the drill bit for drilling glass, the end of the drill bit is generally in the shape of a sharp cone or a hollow drill bit. [0003] In the process of preparing this type of glass drill, after cutting the raw material, various forms of rough grindi...

AI Technical Summary

Problems solved by technology

Among them, in the preparation process, the wall surface of the glass drill needs to be ground and polished. The existing structure has the following problems: 1) The device needs to clamp the glass drill to ensure that the glass drill has a good performance during the process. Fastening performance, the general clamping method for glass drills is to use fixtures to clamp the shank of the drill bit. In the process of grinding the end of the drill bit in this way, the shank of the drill bit is easy to fall off from the fixture tooling or Deflection occurs, resulting in the failure of the connection between the drill bit and the fixture tooling, and the clamping capacity is low, which affects the normal process flow

2) When grinding the drill bit, the cutter head structure is generally used to cut the surface of the raw material. The cutting process is relatively rough, and the size of the drill bit after grinding cannot be accurately controlled.

3) A single process flow of general equipment can only grind and polish a single pair of glass drills, and the efficiency of the preparation process is low
