Two worm gear mechanisms 16 are fixedly arranged on the mounting plate. The support frame 3 is provided with fixing rods 21 in an array manner, and each fixing rod 21 is provided with a group of clamping mechanisms. Two clamping mechanisms are arranged in each group. The first clamping member 17 is fixedly arranged on the fixing rod 21, and the second clamping member 18 is slidably arranged. The driving member 20 is mounted in the receiving cavity 22 of the fixing rod 21, and the driving end of the driving member 20 is connected with the second clamping member 18. Wherein a part of the second clamping member 18 protrudes through the opening, and a groove 19 is provided in the clamping surface of the second clamping member 18 facing the first clamping member 17.

The working principle of the bent cap skeleton welding rotating device is as follows: after the reinforcement frame 6 is placed on the support frame 3, the driving part 20 drives the second clamping part 18 to move towards the first clamping part 17, and after the reinforcement frame 6 is abutted to the first clamping part 17, a part of the reinforcement frame 6 is embedded into the groove 19 to clamp and fix the reinforcement frame 6. After the welding robot 1 finishes single-sided welding, the lifting driving device is started, and the driving motor 13 drives the worm and gear mechanism 16 to rotate, so that the worm wheel is driven to rotate relative to the worm, and the support frame 3 is further enabled to move upwards along the guide post 7. The rotation is started by the rotation driving device 26, the synchronous chain 9 is driven to rotate the rotating member 8, and the lifting driving device, the support frame 3, the guide post 7 and the like rotate accordingly. When the shutter 10 rotates 180 degrees, the shutter rotates to the position of the sensor 11, and the rotation stops. The lifting driving device is started to move the support frame 3 downwards to the working plane of the welding robot 1. The welding robot 1 then welds the other face of the reinforcing bar frame 6.
