Automatic drill bit welding machine

Abstract

The invention discloses an automatic drill bit welding machine. The automatic drill bit welding machine mainly comprises a drill bit body single feeding mechanism, a horizontal drill bit body notch aligning device, an automatic copper bar feeding device, a welding flux adding mechanism, an alloy sheet feeding mechanism, an accurate alloy sheet and drill bit body aligning mechanism, a high-frequency heating device and a post-welding alloy sheet calibrating device, all of which are in linkage with one another. The post-welding alloy sheet calibrating device comprises a calibration clamping port capable of being opened and closed, the calibration clamping port is composed of a left clamping plate and a right clamping plate, and the tail of the left clamping plate and the tail of the right clamping plate are respectively and movably installed on a linear guide rail, and are respectively and fixedly connected with a retractable power source body and a telescopic rod. The inner side of the head of the left clamping plate and the inner side of the head of the right clamping plate are provided with positioning sheets and calibration screws, and the difference value of the internal stretching length of the positioning sheets relative to the internal stretching length of the calibration screws is one second of the difference value of the total width of alloy sheets and the head of a drill bit body. The drill bit body and the alloy sheets can be automatically welded in the whole process, and the automatic drill bit welding machine has the advantages of being high in machining efficiency, good in welding quality and low in human cost.

Description

technical field [0001] The invention relates to drill bit welding equipment, in particular to an automatic drill bit welding machine. Background technique [0002] In order to improve the drilling hardness and drilling efficiency of the drill bit, the existing drill bits generally have a cemented carbide sheet 2' embedded in the head of the drill bit body 1', and the cemented carbide sheet 2' is used as the cutter head for drilling. , the tungsten carbide sheet 2' and the drill body 1' have a split structure, and during processing, the two need to be fixed together by welding, and its structure is as follows figure 1 shown. [0003] But at present, the welding of the above cemented carbide sheet 2' and the drill bit body 1' is all carried out manually, which not only has low production efficiency and high labor intensity, but also causes great damage to the eyes of the operator due to the strong light generated by welding. And the high temperature and poisonous gas that we...

[0003] But at present, the welding of the above cemented carbide sheet 2' and the drill bit body 1' is all carried out manually, which not only has low production efficiency and high labor intensity, but also causes great damage to the eyes of the operator due to the strong light generated by welding. The high temperature and toxic gas generated by welding will also have adverse effects on the body of the operator.
