A conveyor belt is mounted on the base, and a vertical plate is connected to the left side of the upper surface of the base. A fixing box is located on the inner side of the vertical plate, and a lateral adjustment mechanism is located inside the fixing box. The lateral adjustment mechanism includes a movable slider, and an electric push rod is connected to the outer wall of the movable slider via a bracket. L-shaped rods are installed on both outer walls of the conveyor belt, near the vertical plate. Both sets of L-shaped rods are connected to... The device has side plates, with rollers on the inner sides of both sets of side plates. Through the action of the lateral adjustment mechanism, combined with the extension and retraction of the electric push rod, the front and rear positions of the welding gun can be adjusted, enabling rapid spot welding of different positions on automotive sheet metal parts, effectively improving the efficiency of automotive sheet metal spot welding. It can also limit the position of automotive sheet metal parts conveyed on the conveyor belt, effectively improving the accuracy of the spot welding position. However, the above description still has the following defects in actual use: This welding equipment is convenient for adjusting the lateral position of sheet metal parts, but it is not suitable for some cylindrical sheet metal parts. It cannot simultaneously clamp and adjust the welding position of the top edge of the cylinder, reducing the efficiency of spot welding. Therefore, it is necessary to design a more practical and efficient sheet metal spot welding device. Utility Model Content
