[0042] A plurality of grooves 16 are formed in the side wall of each placement slot 15, and a clamping block 17 is slidingly installed in each groove 16. Two guide blocks 37 are fixedly installed on the side wall of the clamping block 17. Two guide grooves are formed in the side wall of the groove 16 and slidingly cooperate with the corresponding guide blocks 37. The cooperation of the guide blocks 37 and the guide grooves is used to enable the clamping block 17 to only move horizontally in the groove 16, so that the clamping block 17 moves towards or away from the center of the placement slot 15.

[0043] A lifting groove 18 is formed in the side wall of each groove 16, and a wedge-shaped block 19 that cooperates with the corresponding clamping block 17 is slidingly installed in each lifting groove 18. When the wedge-shaped block 19 moves upward in the lifting groove 18, the clamping block 17 moves outward from the groove 16 by the cooperation of the upper inclined surface of the wedge-shaped block 19 and the inclined surface at the bottom of the clamping block 17, and the direction of the movement of the clamping block 17 is limited by the guide blocks 37 and the guide grooves. The plurality of clamping blocks 17 move towards each other to fix the support feet located in the placement slot 15.

[0044] A plurality of control assemblies are used to control the movement of the corresponding plurality of clamping blocks 17. Each control assembly includes an annular groove 22 formed in the placement seat 14, and an inner ring gear 23 is rotatably installed in the annular groove 22.

A fixed gear 21 that engages with the inner ring gear 23 is fixedly installed at the bottom of each screw rod 20. When the inner ring gear 23 rotates, it can drive the plurality of fixed gears 21 to rotate in the same direction. At this time, the plurality of screw rods 20 can simultaneously move the plurality of wedge-shaped blocks 19 upward or downward in the corresponding lifting grooves 18, thereby adjusting the position of the clamping block 17 in the groove 16, and achieving the fixing or loosening of the support feet in the placement slot 15.

[0045] A plurality of drive racks 25 are fixedly installed near the midpoint of the welding table 3. A drive gear 24 is fixedly installed at the bottom of one of the screw rods 20 in each placement seat 14 through a fixed rod. Each drive gear 24 cooperates with the corresponding drive rack 25. When the placement seat 14 moves away from the center on the welding table 3, the drive gear 24 rotates under the action of the drive rack 25. At this time, the rotation of the inner ring gear 23 causes the plurality of screw rods 20 to rotate, allowing the plurality of wedge-shaped blocks 19 to simultaneously move upward, thereby automatically achieving the fixing of the plurality of support feet on the placement seat 14 in the early stage of adjusting the position of the plurality of support feet.

[0046] A plurality of flexible sliding assemblies are arranged to allow the placement seat 14 to slide relative to the sliding block 11 when subjected to external force. The flexible sliding assembly comprises a connecting plate 26 fixedly installed on the sliding block 11, the connecting plate 26 is provided with a moving slot 27, and a moving block 28 fixedly connected with the bottom of the placement seat 14 is slidably installed in the moving slot 27. Springs 29 are installed between both ends of the moving block 28 and both ends of the moving slot 27. A rubber rod is fixedly installed in the moving slot 27, and a circular hole in sliding cooperation with the rubber rod is provided in the moving block 28. Under the cooperation of the moving slot 27 and the moving block 28, the placement seat 14 can slide relative to the connecting plate 26, so that the plurality of placement seats 14 can move to a certain extent when the position of the sliding block 11 remains fixed during the welding process of the support, the rigid fixation of the support legs is changed to flexible constraint, avoiding the problem that the internal stress caused by the expansion force of the support that cannot be released during welding causes the deformation of the entire support, effectively improving the quality after welding. The design of the spring 29 can keep the position of the moving block 28 constant in the moving slot 27 when the support does not deform, facilitating accurate adjustment of the position of the plurality of support legs before welding. The cooperation of the rubber rod and the circular hole can increase the moving friction of the moving block 28 in the moving slot 27, so that the moving amplitude of the moving block 28 during the moving and resetting process when subjected to external force in the moving slot 27 will not be too large, and the resetting action can be stably realized.

[0047] The loosening assembly matched with the inner gear ring 23 is installed on the connecting plate 26, and is composed of a rotating rod 30, a large gear 31, a rotating shaft 32, a chain transmission structure 33, a hollow groove 34, a small gear 35 and a fixed rack 36. The rotating rod 30 and the rotating shaft 32 are both rotationally installed in the placing seat 14, the large gear 31 is fixedly installed on the rotating rod 30, and the large gear 31 is engaged with the inner gear ring 23, the chain transmission structure 33 is installed between the rotating rod 30 and the rotating shaft 32, the hollow groove 34 is formed in the connecting plate 26, the small gear 35 is fixedly installed on one end of the rotating shaft 32 located in the hollow groove 34, and the fixed rack 36 is fixedly installed in the hollow groove 34 and engaged with the small gear 35. After the overall welding of the support is completed, due to the limitation of the size of the support, when the plurality of placing seats 14 are moved to the center of the welding table 3 by the driving motor 7, the movement of the placing seat 14 is limited due to the limitation of the size of the support after welding, and the sliding block 11 moves to the center of the welding table 3 along with the rotation of the lead screw 12. At this time, the placing seat 14 slides relative to the sliding block 11, and the cooperation of the fixed rack 36 and the small gear 35 drives the rotating shaft 32 to rotate, and then the rotating rod 30 drives the large gear 31 to rotate under the cooperation of the chain transmission structure 33, so that the inner gear ring 23 drives the plurality of fixed gears 21 to rotate and drives the plurality of wedge-shaped blocks 19 to move downward, and the plurality of clamping blocks 17 are released from the fixing of the support leg. At this time, the welded support can be smoothly taken off from the plurality of placing seats 14, and then the elastic force of the spring 29 makes the placing seat 14 reset on the connecting plate 26. During the resetting process, the cooperation of the fixed rack 36 and the small gear 35 makes the plurality of clamping blocks 17 protrude outward again, and then the continuous operation of the driving motor 7 can make the plurality of placing seats 14 reset to the center of the welding table 3, and during the resetting process, the plurality of clamping blocks 17 are reset into the corresponding grooves 16 by the cooperation of the driving rack 25 and the driving gear 24, so as to facilitate the subsequent placing of the support leg into the placing groove 15.
