Description

Technical Field

[0001] The invention relates to the technical field of spot welding machines, in particular to a steel strip spot welding machine which is easy to clean. Background Art

[0002] Resistance welding refers to a method of using the resistance heat generated by the current passing through the weldment and the contact point as a heat source to locally heat the weldment and pressurize it for welding. During welding, no filler metal is required, the productivity is high, the weldment deformation is small, and it is easy to realize automation. Resistance welding is a method that uses the resistance heat effect generated by the current flowing through the contact surface of the workpiece and the adjacent area to heat it to a molten or plastic state to form a metal bond. There are four main resistance welding methods, namely spot welding, seam welding, projection welding, and butt welding.

[0003] Through searching, Chinese patent announcement number CN209736817U discloses a cleaning type spot welding machine, including a spot welding machine and a welding gun, a slide groove is provided on the right side of the top of the spot welding machine, a slider is embedded in the right side of the inner cavity of the slide groove, a first shell is welded on the top of the slider, a screw is connected to the inner cavity of the first shell through a bearing shaft, a circular plate is interference fit at the bottom end of the outer wall of the screw, a tooth hole is provided on the top circumferential surface of the circular plate, a rocker is connected to the bottom end of the inner cavity of the first shell through a bearing shaft, a gear meshing with the tooth hole is welded on the left side of the rocker, a rectangular block is threadedly connected to the top of the outer wall of the screw, and the left side of the rectangular block extends out of the inner cavity of the first shell and is welded with a second shell. The cleaning type spot welding machine, the device can effectively grind and clean the tin slag on the spot welding machine, save time and effort, avoid the accumulation of tin slag, affect the spot welding accuracy of the welding gun, improve the qualified rate of spot welding products, and better meet the actual use needs.

[0004] With respect to the above-mentioned related technologies, it is believed that the following defects exist:

[0005] 1. Resistance welding requires pressure to be applied to the welding spot during spot welding. After welding, welding spot grooves will be left. If the welding spot grooves are not handled, dust and oil will accumulate. Direct grinding during handling will cause local grooves in the steel strip, making the steel strip uneven.

[0006] 2. When a traditional spot welder is performing clamping welding, one end is usually a fixed point and the other end is a moving end. After welding, the groove of the weld spot at the moving end that applies pressure will be deeper than the groove of the weld spot at the fixed point. Since the grooves of the weld spots at both ends of the steel strip are quite different, the thickness of the two sides of the steel strip will be uneven when the grooves are removed.

[0007] 3. The fixed welding position of traditional electric welding machines cannot perform convenient, comfortable and fast welding of steel bars of various angles and models, and cleaning the welding point grooves will be more cumbersome and difficult due to the fixed angle.
