Robotic automatic large-diameter stud welding gun

Abstract

The invention discloses a robotic automatic large-diameter stud welding gun which comprises a welding gun main body and a welding gun clamp, wherein, the welding gun clamp comprises an upper plate, a lower plate, an upright post, a spring, a jacket and spring leaves; the jacket is arranged in the central position of the upper plate; the jacket penetrates through the upper plate and is fixedly connected with the upper plate; a plurality of elastic blades are arranged at the lower part of the jacket; the blades can grab studs stuck into the blades by virtue of the own elasticity; the lower plate is arranged under the upper plate; the upper plate and the lower plate are connected with each other through the upright post; the outer part of the upright post is sheated with the spring; the upper plate can move up and down along the upright post; a through-hole is formed in the center of the lower plate; the diameter of the through-hole is greater than the maximum diameter of the studs; a plurality of the spring leaves are arranged on the periphery of the through-hole; the spring leaves are uniformly distributed around the through-hole; and the spring leaves can clip ceramic rings penetrating into the spring leaves by virtue of the own elasticity. The robotic automatic large-diameter stud welding gun can be matched with a robot to achieve fully automatic welding, and achieves high effeciency.

Description

technical field [0001] The invention relates to a welding torch, in particular to a robot large-diameter automatic stud welding torch. Background technique [0002] Stud welding is the method of welding metal studs or other similar fasteners to workpieces. In principle, stud welding is very similar to manual arc welding, except that the stud here is not only one of the materials to be welded, but also an electrode without coating. At present, stud welding mainly includes three types of stud arc welding methods: capacitor energy storage stud welding, arc stud welding, and short-cycle drawn arc welding. The capacitive discharge stud welding method is widely used in the connection of small diameter studs (Φ3~Φ6mm) and thin workpieces (1~3mm), especially the stud connection of stainless steel, non-ferrous metals or coated steel plates, most of which are used for Containers and other thin-walled structures, such as electric power industry, automobile manufacturing and electroni...
