Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a suspension bracket welding tool. Background Art

[0002] A suspension bracket refers to a metal structure system that fixes or supports equipment, pipes, cables and other objects by hanging (suspending). It is usually installed on the ceiling, wall or high-altitude frame. Among them, steel pipe brackets are one of the commonly used materials in suspension brackets, and are widely used in scenarios where strength, lightness and corrosion resistance must be taken into account.

[0003] Currently, when welding steel pipe supports, most of the time, the ends of the two steel pipe supports are aligned, and then the connection of the steel pipe supports is welded by a welding device. During the welding process, the steel pipe support is continuously rotated so that the welding device can weld the entire connection of the steel pipe support.

[0004] However, this welding method causes the weld to be located at the end face of the steel pipe bracket. When bearing load, the stress acts directly on the weld, which is prone to cracks and has low stability. Moreover, when the end faces of the steel pipe bracket are directly butt-jointed, even a slight misalignment will cause uneven welds and reduce the load-bearing capacity. Summary of the Invention

When the grinding head 314 is aligned with the steel pipe bracket, the first telescopic rod 31 stops moving, and then the transmission rod 320 is driven to rotate by the rotating assembly, and the transmission rod 320 drives the grinding head 314 to rotate synchronously. During the rotation of the grinding head 314, the two movable plates 34 are driven away from each other by the translation assembly, and the movable plates 34 drive the grinding heads 314 away from each other through the transmission rod 320, so that one of the grinding heads 314 can be inserted into one of them.

[0049] Working principle: When welding the steel pipe bracket, the two steel pipe brackets to be welded are placed on the surfaces of the two support seats 6 respectively. The support seats 6 support the steel pipe brackets and the two steel pipe brackets are positioned by the positioning plate 41. Then, the lifting plate 32 is driven downward by the first telescopic rod 31, and the lifting plate 32 drives the transmission rod 320 to move downward through the moving plate 34. The transmission rod 320 drives the grinding head 314 to move downward. When the grinding head 314 is aligned with the steel pipe bracket, the first telescopic rod 31 stops moving and drives the first gear 317 to rotate through the first motor 316. The engagement of 317 with the second gear 318 drives the rotating rod 319 to rotate, and the rotating rod 319 drives the transmission rods 320 on both sides to rotate through the cooperation of the limit block 322 and the limit groove 321, so that the two grinding heads 314 can rotate synchronously. At the same time, the second motor 36 drives the second threaded rod 38 to rotate, and the threaded connection between the second threaded rod 38 and the movable plate 34 drives the two movable plates 34 to move away from each other, so that one of the grinding heads 314 can be inserted into the interior of one of the steel pipe brackets, thereby making one of the grinding heads 314 able to be inserted into the interior of one of the steel pipe brackets. The conical outer wall of the grinding head 314 performs an inner groove processing on the steel pipe bracket, making its inner wall into a trumpet shape, and at the same time, the other grinding head 314 moves to the outside of the other steel pipe bracket, and chamfers the steel pipe bracket through the conical inner wall of the grinding head 314. After the pretreatment of the end of the steel pipe bracket is completed, the first motor 316 stops rotating, and the second motor 36 drives the second threaded rod 38 to rotate in the opposite direction, so that the grinding heads 314 are close to each other, and the moving plate 34 is driven to move upward by the first telescopic rod 31, and the steel pipe bracket is manually pushed so that one of the steel pipe brackets is inserted into the inside of the other steel pipe bracket. Then, the second telescopic rod 51 drives the mounting block 52 to move downward, and the mounting block 52 drives the semicircular gear ring 53 to move downward through the arc plate 57 until the semicircular gear ring 53 connected to the mounting block 52 and the end of the semicircular gear ring 53 connected to the support seat 6 fit together to form a complete gear ring, and the steel pipe bracket is clamped by the gear ring. Then the staff can weld the steel pipe bracket.
