[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0019] With reference to Figures 1-3 The novel welding fixture comprises a first plate 1 and a second plate 2, and the upper end of the first plate 1 and the lower end of the second plate 2 are fixedly connected through a plurality of support columns.

[0020] The pulling-out mechanism comprises three cores 4 slidably connected to the upper end of the second plate 2, the upper end of the first plate 1 is fixedly connected with an insulating plate 5, the upper end of the insulating plate 5 is fixedly connected with a bottom plate 6, the upper end of the bottom plate 6 is fixedly connected with three air cylinders 7 corresponding to the three cores 4, and the output end of the air cylinder 7 is rotatably connected with the lower end of the corresponding core 4 through a floating ball head 8.

[0021] The upper support and the lower support of the steel three-channel support are placed on the three cores 4 before welding, the three cores 4 stably match the positions of the upper support and the lower support at this time, and after welding, the three air cylinders 7 are adjusted to shrink, the three cores 4 are driven to descend and are pulled out from the upper support and the lower support, and the upper support and the lower support after welding are conveniently taken out.

[0022] And the floating ball head 8 is arranged, so that the movement of the core-pulling 4 has free space, avoiding the product from being deformed after welding due to thermal expansion and cold shrinkage, causing the three core-pulling 4 to rub with the product when being pulled out, causing the wear of the three core-pulling 4 and the product, affecting the quality of the product, and avoiding the subsequent upper and lower supports from not being completely matched, generating a high number of defective products, affecting the production efficiency.
