[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a multi-angle clamping fixture for welding, comprising: a cylinder 1 with a limiting groove 8 on its outer side, the limiting groove 8 being a groove with the center of the cylinder 1 as the center; a support mechanism located on one side of the axis of the cylinder 1, the support mechanism including an arc-shaped rod 2 fixed to one side of the cylinder 1 and a support seat 5 for supporting and fixing the arc-shaped rod 2; a clamping part located on the outer side of the cylinder 1, the clamping part including a fixed angle iron 6 fixed to the outer side of the cylinder 1 and a sliding support block 7 slidably installed on the outer side of the limiting groove 8, a support plate 10 fixed to one side of both the fixed angle iron 6 and the sliding support block 7, and a pressing screw 17 threadedly connected to one side of the support plate 10; an adjustment assembly located at the end of the pressing screw 17, the adjustment assembly including an adjustment plate 13 located at the end of the pressing screw 17, and a lifting plate 14 mounted on one side of the adjustment plate 13 for adjusting the clamping thickness.

[0024] It should be noted that in this invention, the rectangular rod to be welded is placed on one side of the adjusting plate 13. The rectangular rod is fixed by the compression of the adjusting plate 13 and the pressing screw 17. Then, the sliding support block 7 is rotated to make the two rectangular rods come into contact. By adjusting the angle of the adjusting plate 13, the contact position of the two rectangular rods is offset from the cylinder 1, which facilitates welding at the connection. When one of the rectangular rods is fixed in advance, the fixing angle iron 6 and the adjusting plate 13 are clamped on the fixed rectangular rod. Then, the other rectangular rod to be welded is clamped on one side of the sliding support block 7. Then, the sliding support block 7 is rotated to make the rectangular rod on one side of the sliding support block 7 come into contact with the other rod, thus connecting the two rectangular rods. By adjusting the position of the sliding support block 7, it is possible to weld rectangular rods with different tilt angles, which facilitates welding.

[0025] Please see Figure 2 , 3 As shown, a connecting block 3 is fixedly connected to the top of the support base 5, and the arc-shaped rod 2 is slidably installed in the middle of the connecting block 3. A fastening bolt 4 for fixing the arc-shaped rod 2 is threadedly connected to one side of the connecting block 3.

[0026] It should be noted that when the cylinder 1 needs to be tilted, the fastening bolt 4 is loosened outward, and then the arc-shaped rod 2 slides inside the connecting block 3, so that one end of the arc-shaped rod 2 drives the cylinder 1 to tilt upward. When it reaches a suitable angle, the fastening bolt 4 is tightened, so that the end of the fastening bolt 4 presses against the arc-shaped rod 2 and fixes the arc-shaped rod 2 in place, thereby adjusting the angle of the welding position.

[0027] Please see Figure 1 As shown, an adjusting bolt 9 is slidably connected to the middle of the limiting groove 8. The end of the adjusting bolt 9 is fixedly connected to the sliding support block 7. A nut is threadedly connected to the outer side of the adjusting bolt 9. The limiting groove 8 is located between the nut and the sliding support block 7.

[0028] It should be noted that this utility model adjusts the friction at the connection between the sliding support block 7 and the cylinder 1 by adjusting the tightness of the nut on the outside of the bolt 9, so that the friction can be adjusted according to the size of the object being clamped, and the sliding support block 7 can stop at the designated position when it is rotated to the designated position, which facilitates welding processing.

[0029] Please see Figure 4 As shown, a fixing nut 11 is fixedly connected to the top of the support plate 10, and a pressing screw 17 is threadedly installed in the middle of the fixing nut 11. A connecting plate 12 is rotatably connected to the end of the pressing screw 17, and the connecting plate 12 is slidably connected to the support plate 10.

[0030] It should be noted that when the present invention clamps an object, the rotating extrusion screw 17 moves to one end under the action of the thread of the fixing nut 11. The extrusion screw 17 drives the adjusting plate 13 to move towards the fixing angle iron 6 or the sliding support block 7 through the connecting plate 12. In this way, the rectangular rod is clamped and fixed by the cooperation of the adjusting plate 13 with the fixing angle iron 6 or the sliding support block 7.

[0031] Please see Figure 4 , 5 As shown, the adjusting plate 13 has an L-shaped structure and is fixedly connected to the connecting plate 12. The top of the adjusting plate 13 is rotatably connected to the lifting screw 16, which is threadedly connected to the lifting plate 14. The middle part of the adjusting plate 13 is provided with a lifting limit groove 15 that is slidably connected to the lifting plate 14.

[0032] It should be noted that when the relative height of the clamped object and the cylinder 1 needs to be adjusted, the welding position is misaligned with the cylinder 1. By rotating the lifting screw 16, the lifting plate 14 moves upward along the lifting limit groove 15. The object carried by the lifting plate 14 moves along the axis of the cylinder 1, so that the welding position is misaligned with the cylinder 1, preventing obstruction and interference with the welding.
