[0002] Resistance welding is a method of welding in which the metal parts to be welded are overlapped and placed between two electrodes. After a certain force is applied by the electrodes to press the plates together, current flows from one electrode through the plates to the other electrode within a given time (an extremely short time), and the resistance heat generated by the current flowing through the contact surface of the joint and the adjacent area is used for welding.
[0003] Some current resistance welding positioning devices and clamping positioning equipment usually use cylinders to push flat steel clamps to clamp and position the body in white.
[0004] When welding the body in white, since most parts of the body are irregular in shape and mostly large, it is difficult to easily clamp and position some irregular workpieces during welding. In addition, due to the irregular shape and large size of the body in white, some welding positions are difficult to weld in the horizontal direction, resulting in the inability to easily perform positioning welding. Therefore, a body in white resistance welding positioning device that is easy to adjust is proposed to solve the above problems. Utility Model Content
