Arc discharge type stud welding gun detachable handle

Abstract

The invention discloses an arc discharge type stud welding gun detachable handle. The arc discharge type stud welding gun detachable handle comprises a handle body, a handle fixing seat, probes and aPCB and is characterized in that the handle body is arranged below a welding gun body through the handle fixing seat, the probes and the PCB are arranged in the handle body, the two probes are fixed on the PCB, and the PCB contacts with contacts inside the welding gun body through the probes so as to connect a switch circuit. The arc discharge type stud welding gun detachable handle has the advantages that when manual welding is performed, the switch circuit is connected by the contacting between the probes and the contacts inside the welding gun body; when an arc discharge type stud welding gun uses a mechanical arm during work, bolts on the handle fixing seat and the welding body are demounted, the handle body, the PCB and the probes are demounted, the handle fixing seat is mounted finally, and the problem that when an arc discharge type stud welding gun uses the mechanical arm, the protruding handle is difficult in clamping in the prior art is solved; by the detachable handle, fastconversion between the manual welding and the mechanical arm automatic welding can be achieved effectively.

Description

technical field [0001] The invention relates to the technical field of drawn arc stud welding torches, in particular to a detachable handle of drawn arc stud welding torches. Background technique [0002] Drawn arc stud welding guns are widely used in automobile, shipbuilding, aviation, locomotive and other sheet metal industries. The stud welding gun uses the current output by the welding machine to form an arc between the welding sheet metal parts and the welding studs through the lifting of the electromagnet, so that the welding studs and the sheet metal parts melt at the same time, and then through the control of the controller, the electromagnet is turned off. Current, the conductive end part drives the welding nail to press into the molten pool of the sheet metal part under the pressure of the spring, and the welding is completed at one time. The whole welding process only takes tens of milliseconds. [0003] In the prior art, for example, a drawn-arc stud welding to...

Problems solved by technology

Due to the improvement of the degree of automation and the fact that the electric spark generated by the stud welding gun at the moment of welding is easy to burn the operator, the manipulator is used to hold the drawn arc stud welding gun for welding. Therefore, it is not suitable to clamp when the manipulator is required to work. Most of the existing drawn arc stud welding torches are integrally injection molded.

For example, when the drawn arc stud welding torch needs the manipulator to work, due to the protrusion of the handle, the clamping space of the manipulator is limited, and the clamping is not suitable or cannot guarantee the verticality, so that the welding stud is not good
