Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a positioning device for multi-angle welding equipment. Background Technology

[0002] In the welding and processing of steel structures, positioning devices are required to position and support the workpieces being processed.

[0003] The existing patent document CN219521000U discloses a welding device with a positioning structure. This utility model adopts an adjustable angle structure, which allows for multi-angle docking and fixing of materials. The extrusion-type fixing structure makes operation simple and efficient, while the multi-point positioning structure allows for arbitrary positioning of materials to a designated position for welding.

[0004] However, the positioning structure of existing welding equipment is not conducive to the automatic docking of the welding positions of two sets of workpieces when welding. When the existing welding equipment uses positioning devices to weld workpieces at multiple angles, the position and angle of the workpieces need to be manually adjusted. This operation not only increases the labor intensity of the workers, but also results in low welding efficiency and low degree of automation. Utility Model Content

The support frame 2 is located on the upper surface of the support plate 305. After the angles of the two sets of workpieces are adjusted, the drive motor 302 drives the moving block 304 to move on the double-sided lead screw 303. The moving block 304 drives the support plate 305 to move, so that the two sets of support frames 2 move towards each other at a uniform speed until the welding points of the two sets of workpieces are fully aligned, and then welding can be performed.

[0028] The support mechanism 4 includes a slider 401, which is fixedly installed on the side of the support plate 305 away from the moving block 304. A sliding rod 402 is fixedly connected to the inner side of the support base 1, and the slider 401 is slidably connected to the sliding rod 402. A support rod 403 is fixedly connected to the bottom end of the support plate 305, and the support rod 403 is slidably connected to the support base 1. Circular plates 404 are fixedly connected to both sides of the top end of the support frame 2. An adjusting motor 405 is fixedly installed on one side of the circular plate 404. A rectangular frame 406 is fixedly connected to the transmission end of the adjusting motor 405 through the circular plate 404. A fixed seat 407 is fixedly connected to the inner side of the circular plate 404. The rectangular frame 406 is rotatably connected to the fixed base 407 on the side away from the adjusting motor 405.

The positioning mechanism 5 includes a drive motor 501, which is fixedly installed at the bottom of the inner side of the rectangular frame 406. A U-shaped mounting platform 502 is fixedly connected to the transmission end of the top of the drive motor 501. First telescopic cylinders 503 are fixedly installed on both sides of the U-shaped mounting platform 502. The transmission end of the first telescopic cylinder 503 passes through the rectangular frame 406 and is fixedly connected to a first pressing plate 504. The upper surface of the rectangular frame 406... A second telescopic cylinder 505 is fixedly installed in the middle of the surface. The transmission end of the second telescopic cylinder 505 passes through the rectangular frame 406 and is fixedly connected to a connecting rod 506.

The connecting rod 506 is rotatably connected to the connecting disc 508. When using this device for positioning operations in welding processing, the operator places the two sets of workpieces to be processed into the two sets of rectangular frames 406 respectively, so that the workpieces are positioned above the U-shaped mounting platform 502. The operator pushes the first telescopic cylinder 503 by operating the first telescopic cylinder 503.

The operator operates the drive motor 501 to drive the U-shaped mounting table 502 to rotate, thereby adjusting the angle of the processed workpiece in the horizontal direction. The operator operates the adjusting motor 405 to drive the rectangular frame 406 to rotate. The rectangular frame 406 drives the force rod 408 to rotate on the circular plate 404, thereby adjusting the angle of the processed workpiece in the vertical direction.

[0029] Working Principle: When using this device for positioning welding operations, the operator places two sets of workpieces into two rectangular frames 406, ensuring the workpieces are positioned above the U-shaped mounting platform 502. The operator operates the first telescopic cylinder 503, pushing the first pressing plate 504 into full contact with the workpiece, achieving initial workpiece positioning. The second telescopic cylinder 505 then pushes the second pressing plate 507 into full contact with the top surface of the workpiece, achieving fixed clamping and ensuring the stability of the workpiece assembly. The operator operates the drive motor 501, rotating the U-shaped mounting platform 502, thereby adjusting the horizontal angle of the workpiece. In this process, the operator operates the adjusting motor 405, which drives the rectangular frame 406 to rotate. The rectangular frame 406 then drives the force-bearing rod 408 to rotate on the circular plate 404, thereby adjusting the vertical angle of the workpiece. After the angles of the two sets of workpieces are adjusted, the drive motor 302 drives the moving block 304 to move on the double-sided lead screw 303. The moving block 304 drives the support plate 305 to move, and the support plate 305 drives the slider 401 to slide on the slide rod 402. At the same time, it drives the support rod 403 to slide on the support base 1, so that the two sets of support frames 2 move towards each other at a uniform speed until the welding points of the two sets of workpieces are fully aligned, and then welding can be performed.
