A support portion 05 is provided on the top of the welding support system, and the support portion 05 is movably installed above the rotating support system.

[0026] As a specific implementation of the utility model, Figure 1 As shown, the rotating support system includes a longitudinal rotating support device and a horizontal rotating support device 06. The longitudinal rotating support device is installed on the base 01, and the horizontal rotating support device 06 is installed on the top of the longitudinal rotating support device. The longitudinal rotating support device includes a longitudinal driving mechanism 09, a longitudinal transmission mechanism, a column 94 and a rotating platform 08. The column 94 is rotatably installed on the base 01. The longitudinal driving mechanism 09 drives the column 94 to rotate through the longitudinal transmission mechanism. The rotating platform 08 is fixed to the top of the column 94, and the horizontal rotating support device 06 is arranged on the rotating platform 08. The longitudinal driving mechanism 09 includes a longitudinal driving motor 91 and a reducer. The longitudinal transmission mechanism includes a driving gear 92 and a driven gear 93. The longitudinal driving motor 91 drives the driving gear 92 to rotate through the reducer, and the driving gear 92 drives the column 94 and the rotating platform 08 to rotate through the driven gear 93. The rotating platform 08 is also provided with a group of clamping mechanisms 07, which include two symmetrically arranged telescopic cylinders 71, the fixed ends of the two telescopic cylinders 71 are fixedly connected to the rotating platform 08, and the movable ends are provided with clamping blocks 72.

The horizontal driving motor 623 drives the two support wheels 622 on one support seat 621 to rotate through the reducer and the synchronous belt 620.

Its advantages are the same as those when the workpiece is placed longitudinally, so they will not be repeated.

[0036] When in use, loosen the support locking handle 52, rotate the angle of the clamping assembly or the support member 51, or move the connecting rod up and down to fine-tune its height to make it match the weld of the workpiece, thereby achieving fine-tuning of the welding angle and height before welding, providing further preparation work to ensure the welding quality, and then tighten the support locking handle 52.
