Built-in welding gun for machining

Abstract

The invention discloses a built-in welding gun for machining. The built-in welding gun comprises a nozzle, a contact tube, a shunt, a gun neck, an anti-collision mechanism and a gun base and is characterized in that the nozzle is fixedly arranged at the front end of the contact tube, the nozzle is of a necking nozzle structure, the contact tube is fixedly arranged at the front end of the gun neck,the shunt is arranged between the contact tube and the gun neck, the anti-collision device comprises a front seat, screws, nuts, springs and a rear seat, the front seat is fixedly connected with thegun neck, the rear seat is fixedly connected with the gun base, the front seat is connected with the rear seat through the screws and the nuts in a matched manner, the springs sleeve the screws, and two ends of the springs act on the front seat and the rear seat. The built-in welding gun has the advantages that the welding gun and cables are effectively protected through the shunt, the use safetyof the welding gun is increased, the service life of the welding gun is prolonged, and the welding gun is prevented from being destructively damaged during moving dislocation by the aid of the anti-collision mechanism.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a built-in welding torch for machining production. Background technique [0002] Welding gun is an important tool for processing and manufacturing enterprises to carry out welding operations. The working principle of the welding torch is: the welding torch uses the high current of the welding machine, and the heat generated by the high voltage gathers at the tip of the welding torch, melts the welding wire, and the melted welding wire penetrates into the part to be welded. After cooling, the welded object is firmly connected into one. During the welding process, only one side of the steel plate is stressed at the position of the welding point. When welding, the operator first needs to align the head of the welding torch to the welding position. Otherwise, it will lead to misalignment of welding parts and welding deviation. In the prior art, since the weld...

Problems solved by technology

Otherwise, it will lead to dislocation of welding parts, welding deviation

In the prior art, due to the manual operation of welding, the randomness is great, the welding reliability is poor, the welding is inaccurate, and the welding quality is unstable

In the process of automatic welding, the welding torch collides and is prone to damage, and the welding torch has a large current and no insulating components during use, which causes great damage to the welding torch and the cable
