However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a multi-angle fixing mechanism for welding, including a carrying platform 1, connecting pieces 3 are fixedly installed at the four corners of the carrying platform 1, one side of one of the connecting pieces 3 is rotatably connected to the first electric cylinder 4, and one side of two of the connecting pieces 3 are rotatably connected to the positioning seat 10, a rotating platform 9 is rotatably installed inside the carrying platform 1, a rectangular frame 5 is fixedly installed on the top of the carrying platform 1, a clamping rod 6 is slidably connected inside the rectangular frame 5, one end of the clamping rod 6 is slidably connected to the inside of the rotating platform 9, an extension support rod 7 is threadedly connected to the top of the clamping rod 6, and a limiting piece 17 is fixedly installed on the outer wall of the clamping rod 6, one of the limiting pieces 17 is overlapped on the upper surface of the rectangular frame 5, and the other limiting piece 17 is overlapped on the lower surface of the rotating platform 9.

[0026] The specific configuration and function of this embodiment are described in detail below. The four corners of the carrying platform 1 are fixedly installed with connecting pieces 3. The main function of the connecting pieces 3 is to determine the positions of the first electric cylinder 4 and the positioning seat 10. During installation, the positioning seat 10 needs to be installed symmetrically with the first electric cylinder 4, and is installed on both sides of the carrying platform 1 respectively, and the installation position of the first electric cylinder 4 is changed according to the angle that needs to be adjusted;

[0027] When the angle needs to be adjusted, the first electric cylinder 4 pushes the supporting platform 1 to rotate around the positioning seat 10 as the center to change the fixed angle. Special-shaped welded parts can be fixed. The rectangular frame 5 will determine the position of the clamping rod 6. After adjusting the angle of the supporting platform 1, the rotating platform 9 is driven to rotate. The rotation of the rotating platform 9 will drive all the clamping rods 6 to move toward the center of the rectangular frame 5 to complete the clamping and fixation of the welded parts. The extension rod 7 is used to expand the clamping range to accommodate larger welded parts, and the limit plate 17 can determine the position of the clamping rod 6.

[0028] Embodiment 2

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the lower surface of the carrying platform 1 is symmetrically fixedly installed with limiting guide rails 11, and the bottoms of the two limiting guide rails 11 are slidably connected with sliders 12, wherein one side of the slider 12 is movably connected with the second electric cylinder 2, and one side of the two sliders 12 is fixedly connected with a gear rod 13, and the bottom of the rotating platform 9 is fixedly connected with a round block 8, and a driven gear 14 is fixedly installed at the edge of the round block 8, and the driven gear 14 is meshingly connected with the gear rod 13, a circular hole 15 is opened at the junction of the carrying platform 1 and the rotating platform 9, and an arc hole 16 is opened at the junction of the rotating platform 9 and the clamping rod 6.

[0030] The effect achieved by the entire embodiment is that the second electric cylinder 2 pushes the slider 12 to move along the direction of the limiting guide rail 11, the slider 12 drives the gear rod 13 to drive the driven gear 14 to rotate, and the driven gear 14 drives the rotating platform 9 to rotate through the round block 8. Since one end of the clamping rod 6 is slidably connected to the arc hole 16 of the rotating platform 9, a strip hole is opened on the rectangular frame 5. When the rotating platform 9 rotates, the arc hole 16 will drive the clamping rod 6 to move toward the center of the rectangular frame 5.

[0031] The use method and working principle of the device: during installation, install the first electric cylinder 4 according to the direction to be adjusted, install the positioning seat 10 on the other side of the carrying platform 1, then start the first electric cylinder 4 to push the carrying platform 1 to rotate around the positioning seat 10 as the center to change the fixed angle, and after adjusting the angle of the carrying platform 1, start the second electric cylinder 2, and connect the wiring terminals of the second electric cylinder 2 and the first electric cylinder 4 to the external power supply;

[0032] The second electric cylinder 2 pushes the slider 12 to move along the direction of the limiting guide rail 11, and uses the gear rod 13 on the side of the slider 12 to drive the driven gear 14 to rotate, so as to drive the rotating platform 9 to rotate. The arc hole 16 in the rotating platform 9 will drive the clamping rod 6 to move toward the center of the rectangular frame 5 to complete the fixation of the special-shaped welded parts. The extension support rod 7 is used to expand the clamping range to accommodate larger welded parts.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
