DETAILED DESCRIPTION

[0022] Reference Figure 1-Figure 6 As shown, a welding fixture with a clamping positioning block is provided, including a welding robot 1 3, a welding robot 2 4, a welding robot 3 5, a welding robot 4 6, and a welding robot 5 7. The welding robot 1 3, the welding robot 2 4, the welding robot 3 5, the welding robot 4 6, and the welding robot 5 7 are located above the crossbeam support 2 and are used to perform welding operations on the crossbeam support 2. The welding robot 1 3, the welding robot 2 4, the welding robot 3 5, the welding robot 4 6, and the welding robot 5 7 are all fixed on the contraction end of the cylinder, the cylinder used to fix the welding robot 1 3 is fixed on the support seat 1 8, the cylinder used to fix the welding robot 2 4 is fixed on the support seat 2 9, the cylinder used to fix the welding robot 3 5 is fixed on the support seat 3 10, the cylinder used to fix the welding robot 4 6 is fixed on the support seat 4 11, and the cylinder used to fix the welding robot 5 7 is fixed on the support seat 5 12.

[0023] It also includes a welding fixture base plate 1, and a support seat 1 8, a support seat 2 9, a support seat 3 10, a support seat 4 11 and a support seat 5 12 are all fixed on the welding fixture base plate 1.

[0024] When in use, the movement of the telescopic end of the cylinder drives the welding robot 1 3 , the welding robot 2 4 , the welding robot 3 5 , the welding robot 4 6 , and the welding robot 5 7 to move, thereby completing the welding of the beam bracket 2 .

[0025] A symmetrically arranged support frame 13 and a second support frame 14 are installed on the welding fixture bottom plate 1 , and the beam bracket 2 is placed on the support frame 1 13 and the second support frame 14 . The support frame 1 13 and the second support frame 14 are used to support and stabilize the beam bracket 2 .

[0026] A positioning support frame 15 is arranged on the bottom plate 1 of the welding fixture and on the inner side of the support frame 14, and a symmetrically arranged slide rail 17 is installed on the positioning support frame 15. A transverse moving cylinder 16 is laterally arranged on the side of the positioning support frame 15, and also includes a sliding plate 18. The lower surface of the sliding plate 18 is slidably connected to the slide rail 17, and the lower middle part of the sliding plate 18 is connected to the telescopic end of the transverse moving cylinder 16. The movement of the telescopic end of the transverse moving cylinder 16 drives the sliding plate 18 to move forward and backward along the slide rail 17.

[0027] A vertical cylinder 19 is symmetrically arranged above the sliding plate 18, and a vertical contraction end 20 of the vertical cylinder 19 is connected to a clamping block 21 through a rotating shaft, and a clamping positioning block 22 is installed above the clamping block 21. A clamping block 23 is installed below the clamping positioning block 22, and a clamping edge is extended on the upper side of the clamping block 23. The clamping edge is located above the crossbeam bracket 2 and is used to fix the crossbeam bracket 2 to prevent the crossbeam bracket 2 from moving upward. At the same time, the side of the clamping block 23 supports the side of the crossbeam bracket 2 to prevent the crossbeam bracket 2 from moving outward. The crossbeam bracket 2 plays the role of adjusting positioning and correcting positioning during welding, ensuring the correct position of the crossbeam bracket, thereby ensuring the stability of welding.

[0028] The clamping and positioning block 22 is fixed on the top of the clamping block 21 by means of bolts.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
