[0002] Welding of automotive parts is a very important part of the automobile manufacturing process. It mainly involves heating or pressurizing different metal materials, or a combination of both, to achieve atomic bonding and form a permanent connection. Welding production in automobile manufacturing is characterized by large batches, fast production speeds, and high requirements for assembly and welding precision of the welded parts. It is mostly produced in an assembly line manner.

[0003] In the existing technology, after automobile parts are welded, some welds need to be repaired manually. Manual repair welding is prone to problems such as welding leaks and poor quality, which has low production efficiency and seriously affects the factory qualification rate of automobiles. Therefore, an auxiliary welding equipment is needed to position and clamp the workpiece and assist the robot in welding. Utility Model Content

[0032] When the adjusting rod 8 is in the state of contraction, the adjusting rod 8, the clamping plate seat 10, the fixing block 12 under the adjusting rod and the two first clamping plates 11 and other related components are in the vertical state together with the adjusting rod 8. When the automobile parts are assisted in positioning, the automobile parts are placed in the position where the equipment matches them, and the cylinder 5 pushes the connecting rod 6 upward.

The upward movement of the connecting rod 6 pushes one end of the adjusting rod 8 and the linkage block 7 movably connected, and because the two adjusting support plates 9 connected to the outer wall of the adjusting rod 8 are movably connected to the upper right end of the fixed plate 3, the adjusting rod 8 rotates counterclockwise while rotating counterclockwise with the connection point between the adjusting support plate 9 and the fixed plate 3 as the center of the circle, thereby driving the components associated with the adjusting rod 8 and the two first clamping plates 11 to rotate counterclockwise together until the two first clamping plates 11 are in contact with the two second clamping plates 17, thereby positioning and clamping the parts to be welded. When the cylinder 5 runs in the opposite direction, the two first clamping plates 11 can be separated from the two second clamping plates 17, making it convenient to remove the workpiece.

[0037] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but are not intended to limit the scope of the present invention.
