Description

Technical Field

This technology discloses "including a welding machine body, a welding mechanism, a transmission mechanism and a lower pressure arm, and the welding mechanism, the transmission mechanism and the lower pressure arm are all installed on the welding machine body; the welding machine body provides electric energy for the welding mechanism, the transmission mechanism adjusts the welding mechanism, and the welding mechanism welds the workpiece, etc. The technical scheme has the following features: the workpiece is placed in the middle of the welding mechanism, the staff holds the lower pressure arm tightly, and presses the lower pressure arm downward to move the lower pressure arm downward, and then transmits power to the welding mechanism through the transmission mechanism, so that the welding mechanism welds the workpiece, thereby improving the practicality of the equipment and other technical effects";

[0004] With respect to the above-mentioned related technologies, the inventor believes that the existing transfer arm mechanism is too complicated and has a poor transfer effect. The transfer arm mechanism does not have a mechanism with a fixed moving distance. When spot welding the workpiece, it is necessary to move the workpiece to be spot welded from one station to another for processing. There is no fixed distance moving mechanism, which makes it inconvenient to transfer the workpiece well, thereby reducing the use effect of the transfer arm mechanism. Secondly, the existing transfer arm mechanism does not have a lifting mechanism. When transferring the workpiece, it is necessary to adjust the height of the arm body to facilitate the picking and placing of the workpiece. There is no lifting mechanism, which makes it inconvenient to quickly adjust the height of the arm body, thereby reducing the use efficiency of the transfer arm mechanism. Utility Model Content
