Abstract
Description
Technical Field
[0001] The present application relates to the field of welding, and in particular to a spot welding auxiliary clamping device and a spot welding device. Background Art
[0002] Spot welding refers to a welding method that uses cylindrical electrodes to form a weld between the contact surfaces of two overlapping workpieces. During the spot welding process, pressure is first applied to bring the workpieces into close contact, and then an electric current is turned on. Under the action of resistance heat, the contact points of the workpieces melt and form a weld after cooling.
[0003] Currently, spot welding of workpieces such as round tubes is typically done manually by hand, securing the workpieces to the joint and keeping them relatively still. Alignment and angle adjustment must be performed simultaneously, leading to potential shaking and misalignment during spot welding. This can lead to angle deviations in the welded parts, poor weld quality, and low work efficiency. Furthermore, manually securing the workpiece during spot welding can easily lead to burns from the arc. Utility Model Content

[0017] In a possible implementation, a spring is further provided between the connecting rod and the movable pliers, one end of the spring is connected to the sliding end of the connecting rod, and the other end of the spring is connected to the movable pliers.
[0018] In a possible implementation, the tail end of the fixed handle is connected to an adjustment rod for adjusting the position of the sliding end of the connecting rod, and the tail end of the adjustment rod is connected to a knob.
[0019] In the above implementation process, the adjustment rod is rotated by the knob to adjust the position of the sliding end of the connecting rod, thereby adjusting the size of the opening of the clamp body and the opening between the first clamping plate and the second clamping plate to facilitate clamping the workpiece.
[0020] In a possible implementation, a release switch for releasing the positioning effect of the connecting rod is connected to the tail end of the movable handle.
