Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically to a welding tooling for a suspension bracket. Background Art

[0002] A suspension bracket refers to a metal structure system that fixes or supports objects such as equipment, pipelines, and cables through a suspension (hanging) method, usually installed on the ceiling, wall surface, or high-altitude frame. Among them, steel pipe brackets are one of the commonly used materials in suspension brackets, and are widely used especially in scenarios that require a balance of strength, light weight, and corrosion resistance.

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

[0004] However, this welding method makes the weld seam located on the end face of the steel pipe bracket. When bearing loads, the stress directly acts on the weld seam, which is prone to cracks and has poor stability. Moreover, when the end faces of the steel pipe brackets are directly butted, even a slight misalignment will cause uneven weld seams and reduce the load-bearing capacity. Summary of the Invention

[0005] The purpose of the present invention is to provide a welding tooling for a suspension bracket to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A welding tooling for a suspension bracket includes a welding platform. A support frame and two symmetrically distributed support seats are fixed on the surface of the welding platform. A pretreatment mechanism is arranged between the support seats. The pretreatment mechanism is used to perform external groove machining and internal groove machining on the ends of two steel pipe brackets respectively. Positioning mechanisms are arranged on the sides of the support seats away from each other. The positioning mechanisms are used to position the steel pipe brackets. A rotating mechanism is arranged on the top of the welding platform. The rotating mechanism is used to drive the steel pipe brackets to rotate. When welding the steel pipe brackets, the support seats support the steel pipe brackets, and the two steel pipe brackets are positioned by the positioning mechanisms, so that the ends of the two steel pipe brackets close to each other are mirror-distributed with the pretreatment mechanism as the center. The pretreatment machine performs external groove machining and internal groove machining on the ends of the two steel pipe brackets close to each other respectively, processes the inner wall of one pipe bracket into a flared shape, and processes the outside of the other steel pipe bracket into a conical shape, so that one steel pipe bracket can be inserted into the other steel pipe bracket. During the welding process, the rotating mechanism drives the two steel pipe brackets to rotate synchronously, facilitating the staff to weld the entire connection part of the steel pipe brackets.

Subsequently, the rotating assembly drives the transmission rods to rotate. The transmission rods drive the grinding heads to rotate synchronously. During the rotation of the grinding heads, the translation assembly drives the two moving plates to move away from each other. The moving plates drive the grinding heads to move away from each other through the transmission rods, so that one grinding head can be inserted into one of the steel pipe brackets. The inner wall of the steel pipe bracket is processed into a flared shape by the conical outer wall of the grinding head, and at the same time, the other grinding head moves to the outside of the other steel pipe bracket.

The third gear meshes with the semi-circular toothed ring; by driving the mounting block to move downward through the second telescopic rod, the mounting block drives the semi-circular toothed ring to move downward through the arc-shaped plate until the bottom of the mounting block fits against the top of the steel pipe support. After the bottom of the mounting block fits against the top of the steel pipe support, the semi-circular toothed rings connected to the mounting block and the semi-circular toothed rings connected to the support seat just fit together to form a complete toothed ring, and the steel pipe support is clamped inside. During the welding process, the third motor drives the third gear to rotate through the rotating shaft, the third gear drives the semi-circular toothed ring to rotate, and the two semi-circular toothed rings drive the steel pipe support to rotate, facilitating the staff to connect the entire connection of the steel pipe support.

Specific implementation mode

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0027] In one embodiment, please refer to Figure 1 , a hanging bracket welding tooling, including a welding platform 1, on the surface of the welding platform 1, a support frame 2 and two symmetrically distributed support bases 6 are fixed. A pretreatment mechanism 3 is arranged between the support bases 6. The pretreatment mechanism 3 is used for performing external groove processing and internal groove processing on the end parts of two steel pipe brackets respectively. Positioning mechanisms 4 are arranged on the sides of the support bases 6 away from each other. The positioning mechanisms 4 are used for positioning the steel pipe brackets. A rotating mechanism 5 is arranged on the top of the welding platform 1. The rotating mechanism 5 is used for driving the steel pipe brackets to rotate; In this embodiment, when welding steel pipe supports, the two steel pipe supports to be welded are respectively placed on the surfaces of two support seats 6. An arc-shaped groove 58 adapted to the steel pipe support is provided at the top of the support seat 6. The support seat 6 supports the steel pipe support, and the two steel pipe supports are positioned by the positioning mechanism 4, so that the ends of the two steel pipe supports close to each other are mirror-distributed with the pretreatment mechanism 3 as the center. After the steel pipe supports are placed, the pretreatment machine is used to perform external groove machining and internal groove machining on the ends of the two steel pipe supports close to each other respectively. The inner wall of one of the pipe supports is machined into a trumpet shape, and the outside of the other steel pipe support is machined into a conical shape, so that one steel pipe support can be inserted into the other steel pipe support, effectively improving the connection strength between the steel pipe supports and ensuring the stability between the steel pipe supports. After the steel pipe supports are butted, the staff can weld the connection of the steel pipe supports through the welding device. During the welding process, the two steel pipe supports are driven to rotate synchronously by the rotating mechanism 5, which is convenient for the staff to weld the entire connection of the steel pipe supports, effectively improving the welding efficiency of the steel pipe supports.

[0028] Please refer to Figure 2 , the positioning mechanism 4 includes a positioning plate 41 arranged on the mutually remote sides of the support seats 6. A chute 42 is provided on the surface of the welding platform 1. The lower end of the positioning plate 41 is located inside the chute 42 and is slidably connected to the chute 42. A first threaded rod 43 penetrates through the positioning plate 41. The first threaded rod 43 is threadedly connected to the positioning plate 41. One end of the first threaded rod 43 is rotatably connected to the inner wall of the chute 42, and the other end of the first threaded rod 43 penetrates through the side wall of the welding platform 1 and is rotatably connected to the side wall of the welding platform 1; When welding the steel pipe supports, the steel pipe supports can be positioned by the positioning plate 41, so that the ends of the two steel pipe supports close to each other are mirror-distributed with the pretreatment mechanism 3 as the center, effectively ensuring the pretreatment effect of the pretreatment mechanism 3 on the ends of the steel pipe supports. And the positioning plate 41 can play a tightening effect on the steel pipe supports, thus avoiding the offset phenomenon of the steel pipe supports during pretreatment, further ensuring the pretreatment effect of the pretreatment mechanism 3 on the ends of the steel pipe supports. In addition, the position of the positioning plate 41 can be adjusted by the threaded connection between the first threaded rod 43 and the positioning plate 41, so that the positioning plate 41 can position steel pipe supports of different lengths, effectively improving the applicable range of the tooling. The chute 42 can play a limiting role on the positioning plate 41 and can ensure the stability of the positioning plate 41.

[0029] Please refer to Figure 3 and Figure 5, the pretreatment mechanism 3 includes first telescopic rods 31 fixedly connected to the top of the support frame 2 and symmetrically distributed. A lifting plate 32 is fixed to the lower end of the first telescopic rod 31. The lifting plate 32 is slidably connected to symmetrically distributed moving plates 34. The moving plates 34 are connected to the lifting plate 32 through a translation component. The translation component is used to drive the moving plates 34 to move mirror-symmetrically. Transmission rods 320 penetrate through the interiors of the moving plates 34. The transmission rods 320 are rotatably connected to the moving plates 34. The ends of the transmission rods 320 close to each other are connected with a rotating component. The rotating component is used to drive the transmission rods 320 to rotate synchronously. Grinding heads 314 are fixed to the ends of the transmission rods 320 away from each other. The outer part of one of the grinding heads 314 is conical, and the inner part of the other grinding head 314 is conical; After the steel pipe support is positioned, the first telescopic rod 31 drives the lifting plate 32 to move downward. 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 support, the first telescopic rod 31 stops moving. Subsequently, the rotating component drives the transmission rod 320 to rotate. The transmission rod 320 drives the grinding head 314 to rotate synchronously. During the rotation of the grinding head 314, the translation component drives the two moving plates 34 to move away from each other. The moving plates 34 drive the grinding heads 314 to move away from each other through the transmission rods 320. As a result, one of the grinding heads 314 can be inserted into one of the steel pipe supports. The inner bevel of the steel pipe support is processed through the conical outer wall of the grinding head 314, making its inner wall become trumpet-shaped. At the same time, the other grinding head 314 moves to the outside of the other steel pipe support. The chamfer of the steel pipe support is performed through the conical inner wall of the grinding head 314. After the pretreatment of the end of the steel pipe support is completed, the rotating component stops driving the transmission rod 320 to rotate. The translation component drives the moving plates 34 to move closer to each other. Subsequently, the first telescopic rod 31 can drive the lifting plate 32 to move upward. Finally, one of the steel pipe supports is inserted into the other steel pipe support, effectively improving the stability of the two steel pipe supports and ensuring the welding effect of the steel pipe supports subsequently.

[0030] Please refer to Figure 4, the rotating assembly includes a fixing plate 315 fixedly connected to the bottom of the lifting plate 32. A first motor 316 is installed on the side wall of the fixing plate 315, and a first gear 317 is installed at the output end of the first motor 316. A rotating rod 319 penetrates through the inside of the fixing plate 315, and the rotating rod 319 is rotatably connected to the fixing plate 315. A second gear 318 is fixed to the outside of the rotating rod 319, and the second gear 318 meshes with the first gear 317. Both ends of the rotating rod 319 extend into the two transmission rods 320 respectively and are slidably connected to the inner wall of the transmission rod 320. A limiting component is provided between the rotating rod 319 and the transmission rod 320, and the limiting component is used to limit the transmission rod 320, so that the transmission rod 320 can rotate following the rotating rod 319; When processing the inner bevel and outer bevel of two steel pipe supports, start the first motor 316. The first motor 316 drives the first gear 317 to rotate. The rotation of the first gear 317 drives the rotating rod 319 to rotate through the meshing with the second gear 318. The rotating rod 319 drives the transmission rods 320 on both sides of it to rotate through the limiting component, so that the two grinding heads 314 can rotate synchronously and complete the pretreatment of the ends of the steel pipe supports.

[0031] Please refer to Figure 5 , the limiting component includes limiting blocks 322 that are symmetrically distributed and fixed to the outside of the rotating rod 319. Limiting grooves 321 that are symmetrically distributed and adapted to the limiting blocks 322 are provided on the inner wall of the transmission rod 320. The limiting blocks 322 are located inside the limiting grooves 321 and are slidably connected to the limiting grooves 321; When the rotating rod 319 rotates, it drives the transmission rod 320 to rotate through the cooperation of the limiting blocks 322 and the limiting grooves 321, so that the two grinding heads 314 can rotate synchronously. And through the setting of the limiting blocks 322 and the limiting grooves 321, relative displacement can occur between the transmission rod 320 and the rotating rod 319 while the transmission rod 320 rotates.

[0032] Please refer to Figure 3 , the translation assembly includes a second motor 36 and a mounting plate 37 fixed to the top of the lifting plate 32. A second threaded rod 38 is fixed to the output end of the second motor 36. The end of the second threaded rod 38 away from the second motor 36 is rotatably connected to the mounting plate 37. A slideway 35 is provided inside the lifting plate 32. The upper end of the moving plate 34 penetrates through the slideway 35 and is slidably connected to the slideway 35. The second threaded rod 38 penetrates through the moving plate 34 and is threadedly connected to the moving plate 34; When preprocessing the end of the steel pipe support, the second motor 36 is started. The second motor 36 drives the second threaded rod 38 to rotate. Through the threaded connection between the second threaded rod 38 and the moving plate 34, the two moving plates 34 are driven to move away from each other, so that one of the grinding heads 314 can be inserted into one of the steel pipe supports, and the other grinding head 314 can move to the outside of the other steel pipe support. The second threaded rod 38 can be a bidirectional threaded rod. The rotational connection between the mounting plate 37 and the second threaded rod 38 can effectively improve the stability of the second threaded rod 38 during rotation. The slideway 35 can play a limiting role on the moving plate 34, effectively improving the stability of the moving plate 34 during movement.

[0033] Please refer to Figure 4 , a cleaning component is provided on each of the moving plates 34. The cleaning component is used to clean the preprocessed steel pipe support; After the preprocessing of the steel pipe support is completed, the first telescopic rod 31 drives the moving plate 34 to move upward through the lifting plate 32. During the upward movement of the moving plate 34, the cleaning component will clean the end of the steel pipe support, thereby blowing off the iron filings generated during the preprocessing process, avoiding the influence of the iron filings adsorbed on the surface of the steel pipe support on the subsequent welding, and ensuring the welding effect of the subsequent steel pipe support.

[0034] Please refer to Figure 4 , the cleaning component includes a pneumatic cylinder 39 fixedly connected to the top of the support frame 2. A piston 310 is slidably connected inside the pneumatic cylinder 39. A support rod 311 is fixed to the bottom of the piston 310. The lower end of the support rod 311 is fixedly connected to the lifting plate 32. An air hole 313 is provided on one side of the moving plate 34 close to the support seat 6. The air hole 313 penetrates through the top of the moving plate 34. The air hole 313 is communicated with an air pipe 312, and the other end of the air pipe 312 is communicated with the pneumatic cylinder 39; After the preprocessing of the steel pipe support is completed, the first telescopic rod 31 drives the moving plate 34 to move upward through the lifting plate 32. During the upward movement of the moving plate 34, the support rod 311 is also driven to move upward. The support rod 311 drives the piston 310 to move upward inside the pneumatic cylinder 39. The piston 310 squeezes the gas above it, so that the gas inside the pneumatic cylinder 39 enters the air hole 313 through the air pipe 312, and finally is discharged from the air hole 313 and acts on the end of the steel pipe support. At the same time, as the moving plate 34 moves upward, the gas blown out from the air hole 313 passes over the end of the steel pipe support, thereby playing a cleaning role on the steel pipe support, avoiding the influence of the iron filings adsorbed on the surface of the steel pipe support on the subsequent welding, and ensuring the welding effect of the subsequent steel pipe support. In order to ensure the cleaning effect on the end of the steel pipe support, the number of the air holes 313 can be set to multiple.

[0035] Please refer to Figure 3, a pressing block 33 for pressing the steel pipe support is fixed to the bottom of the lifting plate 32; When preprocessing the steel pipe support, the first telescopic rod 31 drives the moving plate 34 to move downward through the lifting plate 32. During the downward movement of the lifting plate 32, the pressing block 33 is also driven to move downward. When the grinding head 314 is aligned with the steel pipe support, the bottom of the pressing block 33 just fits tightly with the top of the steel pipe support. The bottom of the pressing block 33 has an arc-shaped groove 58 adapted to the steel pipe support. By pressing the steel pipe support on the top of the support seat 6 with the pressing block 33, the stability of the steel pipe support can be effectively guaranteed, and the preprocessing effect of the steel pipe support is ensured.

[0036] Please refer to Figure 6 and Figure 7 , the rotating mechanism 5 includes second telescopic rods 51 fixedly connected to the top of the support frame 2 and symmetrically distributed. The bottom of the second telescopic rod 51 is fixed with a mounting block 52. Arc-shaped grooves 58 are provided on both the mounting plate 37 and the side wall of the support seat 6. An arc-shaped plate 57 is slidably connected inside the arc-shaped groove 58. One end of the arc-shaped plate 57 extends outside the arc-shaped groove 58, and the other end of the arc-shaped plate 57 is fixed with a clamping block 59. A clamping groove 510 adapted to the clamping block 59 is provided on the side wall of the arc-shaped groove 58. The clamping block 59 is located inside the clamping groove 510 and is slidably connected to the clamping groove 510. Semi-circular toothed rings 53 are fixed to the ends of the arc-shaped plate 57 outside the arc-shaped groove 58. A third motor 56 is fixed to the surface of the welding platform 1. The output end of the third motor 56 is fixed with a rotating shaft 55. The rotating shaft 55 passes through the support seat 6 and is rotatably connected to the support seat 6. A third gear 54 is fixed to the outside of the rotating rod 319. The third gear 54 meshes with the semi-circular toothed ring 53; After the steel pipe support is pre-treated, one of the steel pipe supports is inserted into the other steel pipe support. Subsequently, the second telescopic rod 51 drives the mounting block 52 to move downward. The mounting block 52 drives the semi-circular toothed ring 53 to move downward through the arc-shaped plate 57 until the bottom of the mounting block 52 fits against the top of the steel pipe support. The bottom of the mounting block 52 has an arc-shaped groove 58 adapted to the steel pipe support. After the bottom of the mounting block 52 fits against the top of the steel pipe support, the semi-circular toothed ring 53 connected to the mounting block 52 just fits against the end of the semi-circular toothed ring 53 connected to the support seat 6 to form a complete toothed ring, and the steel pipe support is clamped inside. Subsequently, the staff can weld the steel pipe support. During the welding process, the third motor 56 drives the third gear 54 to rotate through the rotating shaft 55. The third gear 54 drives the semi-circular toothed ring 53 to rotate. The two semi-circular toothed rings 53 drive the steel pipe support to rotate, facilitating the staff to connect the entire connection of the steel pipe support. After the steel pipe support rotates one circle, the third motor 56 stops operating. The clamping groove 510 can play a limiting role on the arc-shaped plate 57 and the semi-circular toothed ring 53 through the clamping block 59, thereby effectively improving the stability of the semi-circular toothed ring 53 during rotation. In addition, to ensure that the semi-circular toothed ring 53 can drive the steel pipe support to rotate, the arc-shaped grooves 58 at the top of the support seat 6 and the bottom of the mounting block 52 are both smooth. At the same time, to avoid the phenomenon that the semi-circular toothed ring 53 falls off the mounting block 52 during the upward movement of the mounting block 52, an anti-slip gasket is provided between the arc-shaped toothed plate and the arc-shaped groove 58. After the steel pipe support is welded, the second telescopic rod 51 drives the mounting block 52 to move upward, separating the two semi-circular toothed rings 53, facilitating the staff to remove the welded steel pipe support from the support seat 6.

[0037] Working principle: When welding steel pipe supports, the two steel pipe supports to be welded are respectively placed on the surfaces of two support seats 6. The support seats 6 support the steel pipe supports, and the two steel pipe supports are positioned by the positioning plate 41. Subsequently, the first telescopic rod 31 drives the lifting plate 32 to move downward. 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 aligns with the steel pipe support, the first telescopic rod 31 stops moving, and the first motor 316 drives the first gear 317 to rotate. The rotation of the first gear 317 drives the rotating rod 319 to rotate through the meshing of the first gear 317 and the second gear 318. The rotating rod 319 drives the transmission rods 320 on both sides to rotate through the cooperation of the limiting block 322 and the limiting 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. The threaded connection between the second threaded rod 38 and the moving plate 34 drives the two moving plates 34 to move away from each other, so that one of the grinding heads 314 can be inserted into one of the steel pipe supports, and the inner wall of the steel pipe support is processed into a flared shape by the conical outer wall of the grinding head 314. At the same time, the other grinding head 314 moves to the outside of the other steel pipe support, and the chamfer of the steel pipe support is carried out through the conical inner wall of the grinding head 314. After the pretreatment of the end of the steel pipe support is completed, the first motor 316 stops rotating, and the second motor 36 drives the second threaded rod 38 to rotate in the reverse direction, so that the grinding heads 314 approach each other, and the first telescopic rod 31 drives the moving plate 34 to move upward. Then, the steel pipe support is pushed manually, so that one of the steel pipe supports is inserted into the other steel pipe support. Subsequently, the second telescopic rod 51 drives the mounting block 52 to move downward. The mounting block 52 drives the semi-circular toothed ring 53 to move downward through the arc-shaped plate 57 until the semi-circular toothed ring 53 connected to the mounting block 52 fits together with the end of the semi-circular toothed ring 53 connected to the support seat 6 to form a complete toothed ring. The steel pipe support is clamped by the toothed ring. Then, the staff can weld the steel pipe support. During the welding process, the third motor 56 drives the third gear 54 to rotate through the rotating shaft 55. The third gear 54 drives the semi-circular toothed ring 53 to rotate, and the two semi-circular toothed rings 53 drive the steel pipe support to rotate.
