Problems solved by technology

[0003] At present, the welding of welding nuts mostly adopts the traditional method, that is, manually placing the workpiece and the welding nut. The worker first places the workpiece on the welding seat of the resistance welding, and at the same time ensures that the hole of the workpiece is located on the lower electrode on the welding seat, and then places the welding Nut, insert the circular boss of the weldment nut into the hole of the workpiece, start the resistance welding welding, because it is necessary to align the workpiece with the lower electrode, and then align the welding nut with the workpiece, it takes a long time , poor work efficiency, high labor intensity

Abstract

The invention relates to a welding device, in particular to a welding nut automatic welding device which comprises a nut vibration conveying device and a nut conveying rod and further comprises a workpiece positioning device and a nut positioning device. The nut vibration conveying device is connected with the nut conveying rod through a hose. The workpiece positioning device and the nut positioning device are both installed on a welding base. The workpiece positioning device is used for placing a workpiece. The nut positioning device is provided with a lower electrode which is located at thebottom of the workpiece. The nut positioning device is used for limiting the position of a welding nut. An upper electrode is arranged over the lower electrode and installed on an electric resistancewelding lifting table. The nut conveying rod is fixed to one side of a machine frame. One end of the nut conveying rod is located above the nut positioning device when extending out. By means of the welding device, the clamping time of the workpiece and the welding nut is shortened, work efficiency is improved, labor cost and labor intensity are reduced, omitted welding and excessive welding of the nut can be eradicated, and the welding quality is good.

Description

technical field [0001] The invention relates to a welding device, in particular to an automatic welding device for welding nuts. Background technique [0002] Weld nuts solve the problem that ordinary nuts cannot fix the parent body, and weld nuts have good strength and are convenient to install bolts, and their usage is increasing. Welding nuts are generally welded by resistance welding. Welding nuts include round welding nuts, square welding nuts, hexagonal welding nuts, etc. One side of the welding nut has multiple welding feet and circular bosses. The circular bosses are used for positioning. Solder legs are used for soldering. [0003] At present, the welding of welding nuts mostly adopts the traditional method, that is, manually placing the workpiece and the welding nut. The worker first places the workpiece on the welding seat of the resistance welding, and at the same time ensures that the hole of the workpiece is located on the lower electrode on the welding seat, ...
