Drill bit used for glass drilling and having automatic chip removing function

Abstract

The invention discloses a drill bit used for glass drilling and having an automatic chip removing function. The drill bit comprises a drill bit main body, wherein a water conveying pipeline and a drill bit inner cavity are arranged in the drill bit main body, the drill bit main body is provided with a first relief pressure groove and a second relief pressure groove, one side of the first relief pressure groove is communicated with the second relief pressure groove and the other side is communicated with a drill bit hollow cavity, one side of the second relief pressure groove is communicated with the first relief pressure groove and the other side is communicated with the water conveying pipeline, a spring and a steel ball are arranged in the first relief pressure groove, a safety valve is arranged in the second relief pressure groove, a location plate is arranged in the drill bit inner cavity, a location boss is arranged on the location plate, a communicating hole is arranged in the location plate, the steel ball is of an internal hollow structure, the steel ball comprises an outer layer and an inner layer which can mutually rotate, a plurality of first through holes are uniformly distributed in the circumference of the inner layer, and a plurality of second through holes are uniformly distributed in the circumference of the outer layer. According to the solution, water drained from the drill bit hollow cavity can be used repeatedly, and chips of glass can be effectively collected.

Description

technical field [0001] The invention relates to a drill bit for glass drilling, in particular to a drill bit for glass drilling with automatic chip removal function. Background technique [0002] Now it is used for the drill mechanism when drilling glass. When drilling, the glass drill bit is in close contact with the glass. The water pump supplies water to the middle of the inner cavity of the drill bit through the water delivery pipe. Since there is no water outlet on the side of the drill bit, the water forms a certain pressure in the middle of the drill bit. , the pressure forms resistance to the advancement of the drill bit, which affects the drilling speed of the drill bit and reduces the efficiency; when drilling, the glass slag cannot be discharged from the inner cavity of the drill bit. The pressure has a great impact on the glass; when drilling, only the inside of the drill bit is cooled, and there is no water cooling on the outside of the drill bit, thereby shorte...

AI Technical Summary

Problems solved by technology

[0005] But the above scheme has the following problems when working: 1. When the water pressure in the drill bit inner cavity is too large, the water is discharged from the chip discharge hole. Although it can play a certain decompression effect, the water is discharged from the chip discharge hole 2. The glass shavings generated after drilling will flow out from the chip discharge hole together with water, and the discharged glass shavings will be discharged outside directly like water. There is no recycling device. After drilling is completed , the discharged glass shavings will flow around and need to be cleaned manually, which greatly increases the workload of the operator
