Meson repeater for welding torch

Abstract

The invention discloses a meson continuous emitter for a welding gun. The meson continuous emitter comprises an outer shell, an inner shell and a cylinder; a recessed part for containing a welding meson is formed in the front end of the outer shell; the inner shell can slide front and back relative to the outer shell; the inner shell is provided with elastic clamping pieces; the lower end of the cylinder is fixedly arranged on the inner shell; the upper end of the cylinder is provided with a detachable end cover; welding mesons are stacked in the cylinder; a pressing block is arranged in the cylinder; the pressing block is located above the welding mesons; an elastic component is arranged between the pressing block and the end cover to enable the pressing block to push the welding mesons downwards; and the welding mesons located at the lower end of the cylinder are in direct contact with the outer shell under action of the pressure spring. According to the meson continuous emitter disclosed by the invention, the welding mesons can be rapidly replaced during welding; moreover, the welding mesons are put from the upper end of the cylinder, and before the welding mesons are put, the end cover is opened to take out the elastic component and the pressing block, so that a problem that the welding mesons are hard to put is solved; and the welding mesons at the lower end are in direct contact with the outer shell, so that a phenomenon that poor contact caused by a gap between the inner shell and the outer shell is avoided.

Description

technical field [0001] The invention relates to the field of automobile sheet metal repair spot welders or resistance welders, in particular to a meson repeater for welding guns. Background technique [0002] The existing automobile sheet metal repair spot welding machine uses welding mesons for welding, and a new welding meson needs to be replaced each time welding, and most of them adopt manual replacement, which has many procedures and low work efficiency. [0003] Some foreign new welding torches have introduced meson repeaters, which are similar in structure to the replacement magazines of firearms, such as the disclosed meson repeater of Japanese Patent JP4268603B2, which includes a circular cylinder for stacking welding mesons, and the upper end of the cylinder is A compression spring is provided, and the lower end of the cylinder is open, which is used to press and release the welding meson, and is connected with the welding torch. A sliding box matching the cylinder...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above problems, the object of the present invention is to provide a kind of meson repeater for welding guns, which can quickly replace welding mesons during welding, and simultaneously solve the problems of poor contact between welding mesons and power electrodes and difficult placement of welding mesons
