Description

Welding machine capable of preventing welding head from loosening

Technical Field

The utility model relates to a prevent not hard up welding machine of bonding tool.

Background

The welding gun is a part for performing welding operation in the welding process, is a tool for gas welding, is shaped like a gun, is provided with a nozzle at the front end, and sprays high-temperature flame as a heat source; in the welding process of using the welding gun, a nozzle of the welding gun cannot be close to the surface to be welded for welding due to the fact that some narrow surfaces to be welded are easy to encounter, and the angle of the welding head of the welding gun needs to be adjusted at the moment, so that the nozzle of the welding gun is close to the surface to be welded for welding; welding operators are often required to hold the handle at an angle for welding by rotating or swinging the handle to effect movement and/or rotation of the nozzle relative to the surface to be welded.

Although the nozzle can be welded on a narrow surface to be welded by manually and directly operating the handle, the operation difficulty is high, the operation precision is low, a large amount of physical power of an operator is consumed, and the overall welding efficiency is low; the swing welding gun in the existing welding machine product on the market is improved according to the principle, the swing welding gun is usually arranged on a swing rod, the swing of the welding gun is realized by driving the swing rod to swing, and the distance and the angle between the welding gun and a surface to be welded are further adjusted; for example, patent application No. CN201621100569.6 discloses "an electric iron tower welding gun device capable of adjusting height of a welding gun", which includes: the step motor drives the welding gun vertical oscillating shaft to rotate through the worm gear reducer, the welding gun vertical oscillating shaft drives the welding gun to swing the second connecting rod to move up and down through the welding gun swinging first connecting rod, and then the welding gun swings the second connecting rod to drive the oscillating rod to rotate around the hinge with the rotary supporting plate through the rotary shaft, namely the front end of the oscillating rod is driven to move up and down so as to adjust the distance between the welding gun mechanism and the electric power iron tower.

The oscillating welding gun has the problems that: the span swing is big, and it is not hard up easily to assemble the part after long-term the use, and welder easily runs the position with the central line of relative weldment to cause the phenomenon of false welding and rosin joint easily, influence welding quality, long-term maintenance cost is heavier, if lack the maintenance for a long time and can lead to the bonding tool to drop even, brings the influence to welding work, brings the potential safety hazard even.
