A kind of automatic spot welding equipment

Abstract

The invention discloses automatic spot welding equipment with the advantages that the welding production efficiency is improved, and the work intensity is reduced. The automatic spot welding equipment comprises a welding machine body and an installing base, wherein a rotating device driven by a servo motor is vertically arranged on the installing base, an installing disc is detachably arranged at the upper part of the rotating device, at least four material support welding devices are uniformly distributed and arranged on the installing disc in the periphery direction, each material supporting welding device comprises a welding frame arranged on the installing disc, a lower electrode is arranged in the welding frame, a material jacking rod is movably arranged in the welding frame, the top of the material jacking rod is provided with a material jacking frame, the bottom of the material jacking rod is hinged to a crow bar, the middle part of the crow bar is hinged onto a bottom plate of the welding frame, the end part of the crow bar extends out of the welding frame, an inclined wedge block which is provided with the bottom surface downwards inclined in the rotating direction of a turntable and is used for downwards pressing a part, extending out of the welding frame, of the crow bar is arranged on the installing base, the top of the welding frame is provided with a corresponding lower electrode according to the position to be welded of the materials, and a detection device for detecting whether materials exist on the welding frame or not is arranged in a position, corresponding to the material support welding device in a former position of the welding station, on the installing base.

Description

technical field [0001] The invention relates to an automatic spot welding equipment. Background technique [0002] The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes press the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other. Instantaneous thermal fusion is formed at the two contact resistance points, and the welding current flows from the other electrode along the two workpieces to this electrode to form a loop, without damaging the internal structure of the workpiece to be welded. [0003] The traditional spot welding machine is manually loaded, and then the welding arm is controlled to move down to complete the spot welding, and then the welded materials are unloaded, and then repeat. The welding efficiency is low, the workers continue to work without rest, the labo...
