[0060] The fixing frame 524 is fixed on the slide rail 521, and the fourth bracket 514 is arranged on the fixing frame 524. In this embodiment, the fixing frame 524 is installed on the rightmost slide rail 521, and the fixing frame 524 is connected to the first fixing beam 522. In other embodiments, for the convenience of work disassembly, the fixing frame 524 is not connected to the first fixing beam 522.

[0061] The fence welding tool 2 places the fence 1 on the workbench 500 through the bracket 510, which makes it possible to weld the fence, ensures the accurate placement position, improves the speed of placing the fence 1, and improves the placement accuracy of each workpiece of the fence 1. The angle of the workbench is adjusted by the rotating table, so that the fence 1 can be welded at multiple angles. The rotating frame 400 and the workbench 500 are both provided with welding gun holes 410. After the rotating table is turned over, the back of the fence 1 is welded through the welding gun holes 410, eliminating the step of disassembling and reassembling the workpiece when welding the back of the fence 1, thereby improving the welding efficiency.

[0062] The structure of the above fence tooling 2 can weld workpieces with simple shapes. In order to weld workpieces with more complex shapes, the support frame 520 also includes a second fixed beam 525; the bracket 510 also includes a plurality of fifth brackets 515, a plurality of sixth brackets 516, and a plurality of seventh brackets 517.

[0063] The second fixed beam 525 is fixed on the three left slide rails 521, and a plurality of sixth brackets 516 are arranged on the second fixed beam 525. The second fixed beam 525 is installed in the same manner as the first fixed beam 522.

[0064] The plurality of fifth brackets 515 are arranged in the length direction of the rotating frame 400 to support the first intermediate horizontal bar 140. The fifth bracket 515 is installed on the movable beam 523, and has an L-shaped cross section, and a lower groove 515A is provided on the fifth bracket 515. The lower groove 515A is concave in shape, and has the same cross-sectional shape as the vertical rod 160, and is used to place the vertical rod 160.

[0065] The plurality of sixth brackets 516 are arranged in the length direction of the rotating frame 400 to support the second middle cross bar 150. The sixth bracket 516 is installed on the second fixed beam 525, and the cross section is L-shaped, and an upper slot 516A is provided on the sixth bracket, which has the same shape as the lower slot 515A. One upper slot 516A corresponds to one lower slot 515A, and the upper and lower slots are evenly distributed at the position where the vertical rod 160 is located, and the vertical rod 160 is placed in the upper and lower slots. When the weight of the vertical rod 160 is large, the number of upper and lower slots can also be arranged in multiple to better share the weight of the vertical rod 160.

[0066] The plurality of seventh brackets 517 are disposed on the fixed frame 524 and arranged in the width direction of the rotating frame 400 to support the protruding rods 170 .

[0067] like Figure 6 As shown, in this embodiment, in order to better clamp the fence on the basis of the bracket, the workbench 500 further includes a clamping device 530. The clamping device 530 includes a first telescopic unit 531, a second telescopic unit 532, and a pressing unit 533.

[0069] The second telescopic unit 532 includes two telescopic cylinders 532A, which are also fixedly mounted on the slide rail 521 to push the left rod 120 when the telescopic cylinders 532A are extended, so that the left rod 120, the right rod 130 and the first middle cross bar 140 and the second middle cross bar 150 therebetween are tightened.

[0070] In other embodiments, if the fence is heavy, the number of telescopic cylinders 531A and 532A can be increased to improve the stability of clamping.

[0071] In this embodiment, the first and second telescopic units automatically press toward the fence, stop moving and press the workpiece when they touch the workpiece, thereby achieving the purpose of further fixing the workpiece, simplifying the difficulty of manual fixing and improving welding efficiency.

[0072] The clamping unit 533 includes a compression rod 5331 placed on a plurality of vertical rods 160, and a clamping mechanism 5332 for clamping the compression rod 5331.
