Description

Technical Field

[0001] This invention relates to the field of clamp processing technology, specifically to a welding device for precision machining of clamps. Background Technology

[0002] Fastener clamps, as a common type of fastener, are widely used in various industries such as power, telecommunications, municipal engineering, and construction. They are mainly used to fix cylindrical objects such as utility poles, pipes, and streetlights to prevent displacement, vibration, or overturning, ensuring the safe and stable operation of related facilities. To improve the structural strength and deformation resistance of the clamps and prevent them from undergoing plastic deformation or fracture under load, reinforcing ribs are usually welded at the bends of the clamps in actual production. This welding process is a core step in the precision machining of clamps and directly determines the product quality and service life.

[0003] Currently, welding operations in the precision machining of clamps still face numerous technical challenges, making it difficult to meet the demands of large-scale, high-precision production. Existing welding equipment is largely unsuitable for specific applications and lacks flexible adaptability. Due to the diverse specifications and significant dimensional differences of clamps, dedicated positioning and welding mechanisms are required for different clamp sizes, increasing equipment investment costs and extending the processing time for switching between different clamp sizes, resulting in low production efficiency. While some equipment attempts to achieve multi-specification adaptability, the adjustment process is cumbersome, requiring manual adjustment of the welding head and positioning components, which is difficult to operate and makes it hard to guarantee adjustment accuracy, easily leading to welding misalignment. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device for precision machining of clamps, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding device for precision machining of clamps, comprising a support platform and an inner support circular plate installed on the top of the support platform. Two placement limiting components are symmetrically and slidably installed inside the support platform, and two welding components are symmetrically and movably installed at the bottom of the support platform. Two clamp bodies are placed on the outer side of the inner support circular plate, and reinforcing ribs are provided at the bends of the two clamp bodies. Welding through slots are provided on both sides of the support platform.

[0006] Preferably, both of the placement limiting components include two movable blocks 2, each of the two movable blocks 2 having a snap-fit ​​groove on its top, a snap-fit ​​block being snapped into the inside of each snap-fit ​​groove, and a limiting post being fixedly installed on the top of each snap-fit ​​block, and a connecting block being fixedly installed on the bottom of each of the two movable blocks 2.

[0007] Preferably, the support platform has two symmetrically arranged movable slots II inside, and two movable blocks II are slidably installed on the inner side of the two movable slots II respectively. A magnet block II is fixedly installed inside one side of each of the two movable slots II, and a magnet block I is fixedly installed inside the opposite side of each of the two movable blocks II. The magnetic poles of the opposite side of the magnet block I and the magnet block II are the same.

[0008] Preferably, both welding components include a connecting frame and a welding device, with the welding device movably mounted inside the connecting frame. A welding electric cylinder is fixedly mounted on one side of each of the two connecting frames, and the output end of the welding electric cylinder is fixedly connected to one side of the welding device. Two welding heads are symmetrically mounted on the top of each welding device.

[0009] Preferably, connecting ear plates are fixedly installed on both sides of the two connecting frames, and a movable block three is fixedly installed on the top of each connecting ear plate. A magnet block three is fixedly installed inside one side of each movable block three. A movable groove three is symmetrically opened inside the bottom of the support platform. The movable block three is slidably installed inside the movable groove three. A magnet block four is fixedly installed on one side of the inner cavity of the movable groove three. The magnetic poles of the magnet block four and the magnet block three are the same on the opposite side.

[0010] Preferably, four guide columns are symmetrically fixedly installed at the bottom of the support platform. Each guide column has an arc-shaped through groove inside. An anti-deformation pull strip is movably installed inside the arc-shaped through groove, and the two ends of the anti-deformation pull strip are fixedly connected to one side of the connecting frame and one side of the connecting block, respectively.

[0011] Preferably, two movable blocks are symmetrically fixedly installed on the top of each of the two connecting frames, and a support assembly is fixedly installed on the top of each movable block.

[0012] Preferably, each of the placement support components includes a storage base, the storage base having a storage groove inside, a top pressure plate being movably installed inside the storage groove, sliding grooves being formed at the top and bottom of the inner cavity of the storage base, a guide slide rod being fixedly installed inside the sliding groove, a spring being sleeved on the outer side of the guide slide rod, sliding blocks being fixedly installed at the top and bottom of the top pressure plate, each sliding block having a guide slide groove inside, and the sliding block being slidably installed on the outer side of the guide slide rod through the guide slide groove, the sliding block being slidably installed on the inner side of the sliding groove, and both ends of the spring being fixedly connected to one side of the inner cavity of the sliding groove and one side of the sliding block, respectively, and a placement plate being fixedly installed at the bottom of one side of the storage base, with a reinforcing rib plate placed on top of the placement plate.

[0015] Compared with existing technologies, the advantages of this invention are: It allows for flexible selection of inner support circular plates of corresponding specifications based on the size of the clamp body; simultaneously, the clamp body drives the limiting column and moving block II in linkage, and the magnetic block's repulsive force moves the moving block III and connecting frame, autonomously adjusting the initial position of the welder and welding head without the need for additional manual adjustment mechanisms, thus adapting to the precision machining requirements of clamps of different sizes. The anti-deformation strap maintains a constant length, ensuring stable linkage between the welding components and the limiting components during adjustment, preventing adjustment deviation, significantly improving the equipment's versatility and ease of operation, and reducing the time cost of switching between different clamp specifications. The clamp body is initially positioned using an inner support circular plate. Combined with the lateral limiting of the limiting column and the elastic clamping of the top pressure plate, a double-limiting structure is formed, ensuring a tight fit and precise positioning between the clamp body and the reinforcing rib plate. During welding, the welding cylinder pushes the welding head to move at a uniform speed along the welding position. This, combined with the stable support of the support legs and the anti-deformation straps preventing deviation, avoids equipment shaking or welding head shifting during welding, reducing defects such as incomplete welds, missed welds, and uneven welds. This improves the welding quality of the clamp, thereby increasing the product qualification rate and reducing subsequent rework costs. Attached Figure Description

Magnet blocks 20 are fixedly installed inside the opposite sides of each movable block 18. The magnetic poles of the opposite sides of magnet blocks 20 and magnet blocks 28 are the same. Both welding assemblies include a connecting frame 16 and a welding device 13. The welding device 13 is movably installed inside the connecting frame 16. Welding cylinders 10 are fixedly installed on one side of each connecting frame 16. The output end of the welding cylinder 10 is fixedly connected to one side of the welding device 13. Two welding heads 12 are symmetrically installed on the top of each welding device 13. The two sides of the connecting frame 16 are... Each support platform 1 is fixedly equipped with a connecting ear plate 15. A movable block 21 is fixedly installed on the top of each connecting ear plate 15. A magnet 22 is fixedly installed inside one side of each movable block 21. A movable groove 29 is symmetrically opened inside the bottom of the support platform 1. The movable block 21 is slidably installed inside the movable groove 29. A magnet 27 is fixedly installed on one side of the inner cavity of the movable groove 29. The magnetic poles of the magnet 27 and the magnet 22 are the same on opposite sides. Four guide posts 25 are symmetrically fixedly installed on the bottom of the support platform 1. An arc-shaped through groove 26 is opened inside each guide post 25. An anti-deformation pull strap 17 is movably installed inside the arc-shaped through groove 26. Both ends of the anti-deformation pull strap 17 are fixedly connected to one side of the connecting frame 16 and one side of the connecting block 14, respectively. Two movable blocks 23 are symmetrically fixedly installed on the top of each frame 16. Each movable block 23 has a fixed support assembly on its top. Each support assembly includes a storage base 5, with a storage groove 31 inside. A top pressure plate 11 is movably installed inside each storage groove 31. Sliding grooves 34 are formed at the top and bottom of the inner cavity of the storage base 5. Guide rods 32 are fixedly installed inside each sliding groove 34. Springs 33 are sleeved on the outer side of each guide rod 32. Sliding blocks 36 are fixedly installed at the top and bottom of the top pressure plate 11. Each sliding block 36 has a guide groove 35 inside, and the sliding blocks 36 are slidably installed on the outer side of the guide rods 32 via the guide grooves 35. The sliding blocks 36 are also slidably installed on the inner side of the sliding grooves 34.Furthermore, both ends of the spring 33 are fixedly connected to one side of the inner cavity of the sliding groove 34 and one side of the sliding block 36, respectively. A placement plate 37 is fixedly installed on the bottom of one side of the storage base 5, and a reinforcing rib plate 8 is placed on top of the placement plate 37.

[0027] The working principle of the above technical solution is as follows: First, according to the actual size of the clamp body 4, select an inner support circular plate 3 that is perfectly matched in size, and complete the fixing operation of the inner support circular plate 3. The core can be adjusted according to the size of the clamp body 4 to match the size of the selected inner support circular plate 3, and the initial position of the welding head 12 and the welding device 13 can be adjusted independently. The specific adjustment process is as follows: place the two clamp bodies 4 stably on the outside of the inner support circular plate 3. When placing them, the outside of the clamp body 4 will push the two limiting columns 19 to move synchronously, thereby driving the second moving block 18 to slide smoothly inside the second moving groove 9. The second moving block 18 slides Simultaneously, the bottom connecting block 14 moves synchronously; at this time, the total length of the anti-deformation pull strap 17 remains unchanged. Under the repulsive magnetic force of the magnet block 3 22 and the magnet block 4 27, the moving block 3 21 will slide smoothly inside the moving groove 3 29, driving the connecting ear plate 15 and the connecting frame 16 to move synchronously, thereby autonomously adjusting the initial position of the welder 13 and its top welding head 12, accurately adapting to the size of the clamp body 4 and the inner support circular plate 3; at the same time, when the connecting frame 16 moves, it will drive the storage seat 5 and the top pressure plate 11 to move synchronously. After adjusting to the position that fits the clamp body 4, the two clamp bodies 4 are bent The reinforcing rib plate 8 at the bend is placed steadily on top of the top pressure plate 11. Gently press the reinforcing rib plate 8 to ensure it is firmly placed. Then, double-check the position to ensure that the initial position of the welding head 12 is precisely aligned with the welding start position of the reinforcing rib plate 8 and the clamp body 4, without any offset or misalignment. After confirming that the preliminary preparations are correct, start the welding machine 13. Once the welding machine 13 is operating normally and reaches the welding working state, start the welding electric cylinder 10. The core function of the welding electric cylinder 10 is to push the welding machine 13 and its top welding head 12 along the weld line between the reinforcing rib plate 8 and the clamp body 4. The welding head 12 should be moved slowly and at a constant speed, and during the movement, it should be kept in close correspondence with the welding surface without any deviation. At the same time, the welding head 12 should work continuously and stably to perform a uniform and continuous welding operation at the connection between the two, ensuring that the weld is uniform and firm, and completing the precision welding of the clamp. During the welding process, after the welding operation is completed, the welding machine 13 should be turned off first, and after the welding head 12 has completely cooled down, the welding cylinder 10 should be turned off to avoid damage to the components caused by turning off the equipment at a high temperature. The welded clamp should be gently removed and the weld should be checked to see if it is firm and free of defects. Then the welding residue on the surface of the support platform 1 should be cleaned.

[0028] In another implementation scheme, such as Figures 1-7As shown, the top of the support platform 1 is provided with a plug-in groove 24, the bottom of the inner support circular plate 3 is fixedly installed with a plug-in post 30, and the plug-in post 30 is snapped into the inner side of the plug-in groove 24. The top of the support platform 1 is fixedly installed with support legs 2. There are four support legs 2, and the four support legs 2 are installed in a rectangular symmetrical arrangement at the four corners of the bottom of the support platform 1.

[0029] Check if the insertion post 30 at the bottom of the inner support circular plate 3 is intact. Then, precisely snap the insertion post 30 into the insertion slot 24 at the top of the support platform 1. Gently press the inner support circular plate 3 to ensure that it is firmly connected to the support platform 1 without loosening. This completes the fixing of the inner support circular plate 3. The four support legs 2 provide stable support for the support platform 1, effectively preventing equipment shaking from affecting the welding accuracy. At the same time, observe the welding status to prevent problems such as incomplete welding or missing welding.

[0030] Working principle: First, select an inner support plate 3 that is a perfect fit according to the actual size of the clamp body 4. Check whether the insertion post 30 at the bottom of the inner support plate 3 is intact. Then, precisely snap the insertion post 30 into the insertion slot 24 on the top of the support platform 1. Gently press the inner support plate 3 to ensure that it is firmly connected to the support platform 1 without loosening, thus completing the fixing operation of the inner support plate 3. The core can adjust the initial position of the welding head 12 and the welding device 13 according to the size of the clamp body 4 to match the size of the selected inner support plate 3. The specific adjustment process is as follows: Place the two clamp bodies 4 stably on the outside of the inner support plate 3. When placed, the outside of the clamp body 4 will push the two limiting posts 19 to move synchronously, thereby driving the moving block 18 to slide smoothly inside the moving slot 9. When the moving block 18 slides, it will synchronously drive the bottom connecting block 14 to move synchronously. At this time, the total length of the anti-deformation tension band 17 remains unchanged. The repulsive magnetic force between the magnet block 22 and the magnet block 27 acts as a force. When in use, the moving block 21 will slide smoothly inside the moving groove 29, causing the connecting ear plate 15 and the connecting frame 16 to move synchronously, thereby autonomously adjusting the initial position of the welder 13 and its top welding head 12 to accurately fit the size of the clamp body 4 and the inner support circular plate 3; at the same time, when the connecting frame 16 moves, it will cause the storage seat 5 and the top pressure plate 11 to move synchronously. After adjusting to the position that fits the clamp body 4, the reinforcing ribs 8 at the bends of the two clamp bodies 4 are placed steadily on the top pressure plate 11. The reinforcing ribs 8 are gently pressed to ensure that they are firmly placed. Then the position is checked again to ensure the initial position of the welding head 12. The initial position is precisely aligned with the welding start position of the reinforcing rib plate 8 and the clamp body 4, without any offset or misalignment. After completing the preliminary preparation work and confirming that the preliminary preparation work is correct, the welding machine 13 is started first. After the welding machine 13 is running normally and reaches the welding working state, the welding electric cylinder 10 is started. The core function of the welding electric cylinder 10 is to push the welding machine 13 and the welding head 12 on its top to move slowly and uniformly along the welding position of the reinforcing rib plate 8 and the clamp body 4. During the movement, the welding head 12 must be kept in close correspondence with the welding surface without offset. At the same time, the welding head 12 continues to work stably to connect the two. Perform uniform and continuous welding operations to ensure that the weld seam is uniform and firm, and complete the precision welding of the clamp. During the welding process, the four support legs 2 provide stable support for the support platform 1, effectively preventing equipment shaking from affecting the welding accuracy. At the same time, observe the welding status to prevent problems such as incomplete welding or missed welding. After the welding operation is completed, first turn off the welding machine 13, and after the welding head 12 has completely cooled down, turn off the welding electric cylinder 10 to avoid damage to the parts caused by turning off the equipment at high temperature. Gently remove the welded clamp and check whether the weld is firm and free of defects. Then clean the welding residue on the surface of the support platform 1.
