Automatic stud welding gun

Abstract

The invention discloses an automatic stud welding gun which comprises a welding gun assembly, a ceramic ring clamping assembly, a first lifting assembly and a second lifting assembly, the first lifting assembly comprises a first motor, a lead screw and a sliding base, an output shaft of the first motor is directly or indirectly connected to the lead screw, and the sliding base is in threaded connection to the lead screw; and the welding gun assembly is connected to the sliding base, the ceramic ring clamping assembly is movably connected to the welding gun assembly, and the second lifting assembly is connected to the welding gun assembly and the ceramic ring clamping assembly and used for driving the ceramic ring clamping assembly to move relative to the welding gun assembly. The welding gun assembly is located on the moving path of the ceramic ring clamping assembly and can enable the ceramic ring clamping assembly to be opened. According to the automatic stud welding gun, the strokeof the welding gun assembly is large, and stud welding of complex surfaces is facilitated; and the ceramic ring clamping assembly is prevented from colliding with a ceramic ring, the ceramic ring clamping assembly is effectively protected, and the service life of the ceramic ring clamping assembly is prolonged.

Description

technical field [0001] The invention relates to an automatic stud welding torch. Background technique [0002] Stud welding torch is a device that welds one end of a stud (welding stud / stud) to the surface of a plate (or pipe). Arc stud welding uses the stud (welding stud / stud) itself as the electrode, and the welding arc as the heat source , with the ceramic ring as the protective component, the welding arc burns stably between the stud and the weldment (plate or pipe), after the welding zone of the weldment is heated to form a molten pool and the end of the stud forms a molten layer, The stud is inserted into the molten pool under the pressure of the welding torch, so that the liquid metal is squeezed into the forming groove of the ceramic ring, thereby forming a high-speed implant welding method for the joint. Bolt welding guns are widely used in high-rise steel structure buildings, industrial plant buildings, roads, railways, bridges, towers, automobiles, energy, transp...

AI Technical Summary

Problems solved by technology

[0003] The inventor of the present application found in the research and development process that the existing stud welding torch still has many technical problems to be solved, such as the limited stroke of the welding torch mandrel of the stud welding torch, which is difficult to adapt to the stud welding of the complex workpiece surface ;The ceramic ring fixture cannot be opened before clamping the ceramic ring, and the ceramic ring fixture is easily damaged; the structure of the stud welding torch is complex and takes up a lot of space, etc., and there is room for improvement
