In a specific operation, the two pressing plates 411 initially clamp the first welding component in the front-rear direction by the elastic force generated by the compression deformation of the auxiliary spring 412 in the horizontal pressing mechanism, and then the external motor first operates to drive the bidirectional threaded rod 4132 to rotate forward, so that the movable plate 4131 drives the corresponding pressing plate 411 to clamp and limit the first welding component in the front-rear direction through the cooperation between the bidirectional threaded rod 4132 and the two movable plates 4131.

Then the second cylinder works to drive the lower pressing plate 421 to move downwards synchronously, so that the lower pressing plate 421 has a downward pressing acting force on the first welding part, and therefore limiting and clamping are carried out on the first welding part in the up-down direction.

The second welding part is manually placed between the two rectangular plates 510, then the third cylinder works to enable the telescopic end of the second welding part to extend out, so the movably mounted rectangular plate 510 is close to the fixedly mounted rectangular plate 510, the movably mounted rectangular plate 510 drives the corresponding rubber roller 515 to be in contact with the second welding part and compress the second welding part, then the second welding part can move downwards through the friction force between the rubber roller 515 and the second welding part through the rotation of the rubber rollers 515 on two sides of the second welding part, and the first electric sliding block works to drive the base plate 30 to move right, so that the second welding part is finally aligned with the first welding part.

Finally, the welding process is performed on the first and second welding parts, which are not shown in the drawing, of the external laser welding device provided between the left and right base plates 1 and 2, so that the processing of the required welding parts is completed, and at the same time, after the welding is completed, the welded parts are taken out and all devices are reset.
