Multi-electrode overturning switching type grinding electric resistance welding robot complete machine

Abstract

The invention discloses a multi-electrode overturning switching type grinding electric resistance welding robot complete machine. The multi-electrode overturning switching type grinding electric resistance welding robot complete machine comprises a machine tool, a conveying supporting mechanism, a mechanical arm and a grinding electric resistance welding electrode tip. The grinding electric resistance welding electrode tip comprises an overturning frame and a switching base, the overturning frame is rotationally arranged on the switching base and provided with two ratchet wheels and welding electrodes, the number of ratchets of the ratchet wheels is twice that of the welding electrodes, the switching base is provided with two floating pressing frames, and pressing springs are arranged between the floating pressing frames and the switching base. The switching base is provided with a first pawl mechanism, the first pawl mechanism meshes with the ratchet wheels and hinged to the floatingpressing frames, a second pawl mechanism is arranged on the rear wall of the right side of the switching base, and the second pawl mechanism meshes with the ratchet wheel on the same side and hinged to the floating pressing frame on the same side. Welding work and mechanical operation of multiple specifications are achieved, the welding efficiency is improved, the cost is reduced, the working condition requirement for dense arrangement of multi-specification gradual change welding spots is met, and the welding quality is uniform.

Description

technical field [0001] The invention relates to a complete machine of a multi-electrode flip-switching grinding resistance welding robot. Background technique [0002] Resistance welding refers to the method of using the resistance heat generated by the current passing through the weldment and the contact as the heat source to locally heat the weldment and simultaneously pressurize it for welding. [0003] At present, the welding electrodes are all single-electrode structures, which have poor adaptability to the working conditions of densely arranged multi-standard gradient solder joints, and often require multiple resistance welding mechanisms to be arranged in a pipeline, resulting in low welding efficiency and high welding costs. Contents of the invention [0004] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a complete machine of a multi-electrode flip-switching grinding resistance welding robot. [0005] To achieve t...
