A reamer for cleaning a welding torch

Abstract

A reamer for cleaning welding guns, including a reamer main body and an annular flange arranged at its root; the reamer main body is cylindrical, with a notch extending axially backward to the root of the annular flange; The outer wall of the reamer body is divided into two stages. The outer diameter of the first stage at the front end is smaller than the outer diameter of the first stage at the rear end: the end surface of the first stage at the front end is an involute curve, and the extended end is the first cleaning blade, and the front end surface of the first stage at the rear end. The radial edge corresponding to the rotating end of the first stage of the front end is the second cleaning blade; the inner wall of the reamer body is also divided into two axial stages. The inner diameter of the first stage of the front end is larger than the inner diameter of the first stage of the rear end, and the inner diameter of the first stage of the front end is larger than the inner diameter of the first stage of the rear end. The axial edge close to the second cleaning blade is the third cleaning blade; the end surface of the annular flange is an involute curved surface, and its extended end is the fourth cleaning blade. The invention not only strengthens the strength of the reamer, but also achieves thorough cleaning of the welding gun part, improves the cleaning effect, and improves the welding efficiency.

Description

technical field [0001] The invention relates to the technical field of auxiliary appliances used in cleaning welding torches, in particular to a reamer for cleaning welding torches. Background technique [0002] The nozzles, contact tips, insulating sleeves or shunts installed on the welding torch are all consumable parts used in welding. The consumption rate of the consumable parts during use is related to the level of production costs. At the same time, if the molten melt splashed during welding splashes on the consumables, if it cannot be cleaned effectively, the welding quality will inevitably be affected. In the robot automatic welding process, the efficient cleaning of the welding spatter attached to the welding torch is related to the smooth progress of the entire production cycle. If the reamer installed on the torch cleaning equipment does not clean the spatter attached to the consumable parts of the welding torch thoroughly, it will inevitably require human interv...

AI Technical Summary

Problems solved by technology

If the reamer installed on the torch cleaning equipment does not thoroughly clean the spatter attached to the consumable parts of the welding torch, it is bound to require human intervention and cleaning, that is, manual cleaning, which will waste a lot of production time and reduce the efficiency of automated production

[0003] like figure 1 As shown, the tool body 5 of the existing reamer is straight cylindrical, and is provided with an axially extending strip-shaped gap, and its front end surface is an involute curved surface extending axially, and the front end of the curved surface is a cleaning blade. 51. It is used to clean one end face of the insulating sleeve inside the welding torch. The whole structure is a straight cylinder. The wall thickness of the root of the reamer is thin and the strength is low, which is easy to cause fracture

Therefore, the currently used welding torch cleaning reamer is not comprehensive and thorough enough to clean the nozzle, contact tip, insulating sleeve or shunt inside the welding torch, which restricts the welding efficiency of automatic welding
