Example Embodiment

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Such as figure 1 , 2 , 3 and 4 show a specific embodiment of the servo welding head assembly of the present invention. This embodiment includes a frame 1, a spot welding mechanism 2 and a positioning mechanism 3. The spot welding mechanism 2 and the positioning mechanism 3 are arranged on the frame 1. The spot welding mechanism 2 includes an upper welding head group 21 and a lower welding head group 22. The welding head group 21 is moved up and down by a servo motor. The lower welding head group 22 includes a lower bracket 221 that can move up and down and a lower welding head 222 arranged on both sides of the lower bracket 221 that can move left and right. The positioning mechanism 3 is located in the upper welding head group. Between 21 and the lower welding head group 22, the positioning mechanism 3 includes a positioning claw 31 and ...

Abstract

The invention discloses a servo welding head assembly. In order to be matched with a workpiece with a large structure, the servo welding head assembly is provided with a lower welding head set which can move up and down. The lower welding head set ascends to be matched with the height wherein the workpiece is located, and therefore the servo welding head assembly can be flexibly matched with workpieces with different structures. In addition, lower welding heads stretch into the middle of the workpiece from the two sides, matching is conducted according to specific workpiece shapes, the lower welding heads and upper welding heads above the lower welding heads are matched, a silver point on the upper portion of the workpiece can be well subjected to spot welding, the upper welding heads and the lower welding heads directly make contact from the up-and-down contact surfaces of the silver point and the workpiece for spot welding, and the servo welding head assembly can adapt to workpieces with complex structures; the structure of the lower welding head set which can ascend and descend up and down and a positioning mechanism which can move front and back are both beneficial for the purpose that the workpiece with the large structure moves to the position in front of the servo welding head assembly without being blocked, the structure is reasonable, and the servo welding head assembly can be suitable for welding more workpieces.

Description

technical field [0001] The invention relates to a welding device, in particular to a servo welding head assembly for positioning spot welding of silver points and workpieces. Background technique [0002] At present, in the electrical field, silver points and workpieces are mostly welded to the workpiece by a manual spot welding machine. During spot welding, the workpiece is placed on the tooling manually, and then the silver points are placed on the corresponding position, and finally through welding. head for spot welding. This traditional manual welding method has low efficiency and poor economic benefits. Therefore, more and more automatic welding machines are manufactured to replace traditional manual operations, which not only greatly improves work efficiency, but also avoids the defects that were prone to errors in previous manual operations; such as the welding of silver points and workpieces mentioned above, How to reasonably design the welding structure to match ...
