[0024] It should be noted that the operator can adjust the angle of the auxiliary clamp 301 by sliding the connecting bolt 202 on the inner wall of the sliding groove 201, and then fix the auxiliary clamp 301 by fixing the nut 203. Then the operator needs to place multiple welding parts between the main clamp 4 and the auxiliary clamp 401, and clamp them with the clamping bolt 501, so that the welding parts are clamped between the main clamp 4 and the auxiliary clamp 401 to assist laser welding.

[0025] Specifically, the sliding part 2 includes a connecting block 204 and a connecting bolt 202. The outer wall of the connecting bolt 202 is slidably connected to the inner wall of the sliding groove 201. The connecting block 204 is fixedly connected to the end of the connecting bolt 202 away from the connecting ring 1. The front end of the connecting block 204 is fixedly connected to the end of the auxiliary splint 301 close to the connecting ring 1. The outer wall of the connecting bolt 202 and the end away from the auxiliary splint 301 are threadedly connected with a fixing nut 203.

[0026] It should be noted that the sliding groove 201 is arranged on one side of the outer wall of the connecting ring 1. When the sliding groove 201 slides, the connecting bolt 202 will slide in an arc along the outer wall of the connecting ring 1. The connecting bolt 202 will drive the auxiliary splint 301 to slide in an arc through the connecting block 204. The connecting block 204 is fixedly connected to the auxiliary splint 301 by welding. When the auxiliary splint 301 is adjusted by the connecting bolt 202, the fixing nut 203 can be threadedly connected to the outer wall of the connecting bolt 202. When the threaded connection is engaged, the fixing nut 203 will resist the inner side of the connecting ring 1 to fix the connecting bolt 202.

[0027] Specifically, a main hinge seat 303 is provided on one end of the main splint 3 and the auxiliary splint 301 away from the connecting ring 1 , and an outer wall of the main hinge seat 303 is hinged to an end of the main clamping block 4 close to the connecting ring 1 .

[0028] It should be noted that the main clamping block 4 is shaped like a frame with two ends perpendicular to each other. The main clamping block 4 can clamp the outer wall of the circular tube and the square tube through the frame. The main clamping block 4 can be flipped through the main hinge seat 303. The main clamping block 4 can change the clamped object by flipping.

[0029] Specifically, the clamping part 5 includes a clamping bolt 501 and a threaded baffle 502, wherein one clamping bolt 501 is arranged at the top of the connecting plate 302, and the other clamping bolt 501 is arranged at the top of the chassis 101 and is located at one end close to the positioning clamp 402, the outer walls of the multiple clamping bolts 501 are threadedly connected to the inner walls of the multiple threaded baffles 502, and a secondary hinged seat 403 is provided at one end of the multiple clamping bolts 501 away from the threaded baffle 502.

[0030] It should be noted that when the operator is clamping the weldment, one of the weldments needs to be placed on the top of the positioning clamp 402, and then the operator manually rotates the clamping bolt 501. The clamping bolt 501 will be threadedly engaged with the inner wall of the threaded baffle 502 when rotating, and the clamping bolt 501 will push the auxiliary clamp 401 to move toward the position of the weldment under the threaded engagement, so that the auxiliary clamp 401 will cooperate with the main clamp 4 to clamp the weldment to the top of the positioning clamp 402, and in the same way, another weldment is fixed to the auxiliary clamp 301 at the top of the connecting plate 302, so that the welded ends of multiple weldments are docked and fixed, and finally the operator can laser weld the docking joints using a laser welding machine.

[0031] Specifically, the outer wall of the secondary hinge seat 403 is hinged to the end of the secondary clamping block 401 close to the threaded baffle 502, and the end of the clamping bolt 501 away from the secondary clamping block 401 is provided with an adjustment disk 503. ， The clamping bolt 501 and the secondary hinge seat 403 need to be connected by rotation and insertion.

[0032] It should be noted that the auxiliary clamp 401 can achieve angle adjustment through the auxiliary hinge seat 403, and the auxiliary clamp 401 cooperates with the main clamp 4. When fixing the round tube welded parts, the auxiliary clamp 401 and the main clamp 4 can be flipped at a forty-five degree angle through the auxiliary hinge seat 403 and the main hinge seat 303, and then the round tube parts can be fixed and welded through the auxiliary clamp 401 and the main clamp 4. At the same time, multiple "L"-shaped steel plates can also be clamped to achieve corner welding between plates.

[0033] Working principle of this utility model:

[0034] The specific operation is that the operator needs to slide the auxiliary splint 301 through the connecting block 204 to connect the bolt 202. The connecting bolt 202 will slide on the inner wall of the sliding groove 201. The operator needs to adjust the sliding distance of the auxiliary splint 301 according to the welding angle between the multiple welded parts. Then the operator screws the fixing nut 203 to the outer wall of the connecting bolt 202, and fixes the position of the connecting bolt 202 and the auxiliary splint 301 through the fixing nut 203. Then the operator needs to weld one of them to the inner wall of the main clamping block 4 at the front end of the main splint 3, and then tighten the clamping bolt 501 through the adjusting dial. 503 rotates, and the clamping bolt 501 is threadedly engaged with the inner wall of the threaded baffle 502 through rotation, so that the clamping bolt 501 pushes the auxiliary clamp 401 to move, and the auxiliary clamp 401 is pushed and cooperates with the main clamp 4 to clamp the weldment to the top of the positioning clamp 402, and then the same method is used to clamp another weldment to the top of the connecting plate 302. The operator can use the main hinge seat 303 and the auxiliary hinge seat 403 to adjust the vertical angle of the main clamp 4 and the auxiliary clamp 401, so that the main clamp 4 and the auxiliary clamp 401 can clamp square and cylindrical weldments for laser welding.
