[0033] The working principle and use process of the utility model are as follows: before welding, the workpiece to be welded is placed on the top surface of the conveying roller 301 of the conveying roller frame 1 and conveyed to the welding position, the horizontal electric push rod 203 is started, the movable frame 202 is pulled close to the fixed frame 201, and the roller 204 rolls on the ground to adjust the spacing so that the welded workpiece is in the middle position between the movable frame 202 and the fixed frame 201;

[0034] Then, the lifting electric push rod 305 is started to push the support plate 302 on the top surface of the lifting plate 304 through the gap between the conveying rollers 301 until the top surface of the inflatable strip 303 is higher than the top of the conveying roller 301, and the inflatable strip 303 is used to contact the bottom surface of the weldment.

Because the guide ring 212 can only suppress the sliding of the guide rod 211, the internal threaded sleeve 210 will not rotate. The internal threaded sleeve 210 will push the extrusion plate 213 to approach the weldment, and then the extrusion head 217 at the end of the inner guide blind tube 215 approaches and squeezes the weldment, the spring 216 contracts, and the inner guide blind tube 215 slides along the outer guide blind tube 214. The extrusion head 217 provides stable clamping support according to the surface distribution of the weldment, with more clamping contact points and good clamping effect to prevent shaking during welding. Weldments of different sizes can achieve good clamping effects without replacing the clamping structure, thereby improving welding efficiency.
