Problems solved by technology
[0002] The electric welding equipment currently used mainly includes manual spot welding, special machine multi-spot welding and robot welding. And low maintenance cost, good flexibility, but there are disadvantages such as high labor intensity, low efficiency, inaccurate manual positioning, consistent quality of solder joints and poor appearance quality of solder joints, so it will be difficult to meet people's increasing demand for automobile manufacturing quality higher requirements
[0003] Special machine multi-spot welding is welding by multi-spot welding machine, which is suitable for workpieces with complex welding structures, dense solder joints, small joints, difficult operation, and difficult to guarantee welding quality. However, multi-spot welding equipment requires a lot of investment and Strong specificity, only suitable for welding of a certain product, poor flexibility
[0004] Robotic welding is performed by spot welding robots, which has the advantages of high automation, strong flexibility, and good welding quality, but its initial investment and later maintenance costs are high, the payback period is too long, and the input-output ratio is low, which is not conducive to rapid promotion

Embodiment Construction
[0021] Below in conjunction with specific embodiment, the present invention is further described:
[0022] Such as figure 2 The new puppet welding mechanism with follow-up mechanism shown includes a static electrode group 10 and a moving electrode group 11, and a follow-up mechanism. The follow-up mechanism includes a connection support seat 9, a pincer arm support seat 12, 13 and a cylinder 14, wherein the connection support base 9 is hinged at the middle part of the clamp arm 13 through the clamp arm support base 12, the bottom of the clamp arm 13 is connected with the cylinder 14, the top of the clamp arm 13 is equipped with a moving electrode group 11, and the static electrode group 10 Installed on the connecting support base 9, its position is facing the moving electrode group 11, and the moving electrode group 11 can rotate around the hinge point with the forceps arm 13, and adjust the distance with the static electrode group 10.
[0023] In this example, if figure 1 ...

The invention provides a novel puppet welding mechanism with a servo mechanism. The novel puppet welding mechanism comprises a fixed electrode set, a movable electrode set and the servo mechanism. The servo mechanism comprises a connecting support seat, a clamp arm support seat, a clamp arm and a cylinder. The connecting support seat is hinged to the middle of the clamp arm through the clamp arm support seat. The cylinder is connected to the bottom of the clamp arm. The movable electrode set is mounted at the top of the clamp arm. The fixed electrode set is mounted on the connecting support seat and faces directly to the movable electrode set. The movable electrode set can rotate around a hinge point along with the clamp arm to adjust the position of the movable electrode set relative to the fixed electrode set. The novel puppet welding mechanism is simple in structure, high-quality, efficient and low in cost, good contact of two pairs of electrodes is guaranteed by adjustment of the servo mechanism, and welding points with good appearance quality are achieved.
