Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically to an intelligent variable parameter welding tooling for iron accessories. Background Technology

[0002] Iron fittings refer to various mechanical parts made of iron or iron alloys. They are widely used in power fittings (such as tower bolts, crossarms), mechanical structures (such as flanges and brackets), and building steel structures, and are characterized by high strength and low cost. With the rapid development of industries such as power, transportation, and equipment manufacturing, the diversity of iron component specifications and the complexity of welding processes have significantly increased. The limitations of traditional welding fixtures have become increasingly prominent. In the welding process of iron components, traditional fixtures generally face two major problems:

[0003] On the one hand, traditional tooling often uses rigid fixtures of fixed size, which can only be adapted to iron components of specific shapes and sizes. When the workpiece shape is irregular or changes, it is necessary to frequently change the fixture manually and readjust the positioning, which not only increases the cost of tooling, but also affects production efficiency due to the time spent on changing the shape, thus reducing the practicality of the tooling.

[0004] On the other hand, during or before welding, for iron components welded in different positions, traditional tooling usually fixes the workpiece in a single position. The workpiece needs to be manually adjusted by manually flipping or re-clamping the workpiece multiple times. This not only increases the labor intensity, but also easily leads to poor weld formation due to repeated positioning errors, reducing the flexibility of the tooling. Utility Model Content

[0023] Example

[0024] Please see Figures 1 to 6This utility model provides a technical solution including a base plate 1, two sets of sliding plates 2, and multiple sets of semi-circular clamps 35. Each set of sliding plates 2 has a groove 3 on its top. A first bearing 10 is fixedly connected to the inner wall of each groove 3. A first rotating shaft 11 is rotatably connected inside each of the two first bearings 10. The opposite ends of the two first rotating shafts 11 are fixedly connected to the same first bidirectional lead screw 4. A first drive motor 32 is fixedly connected to one side of each of the two sliding plates 2. The other ends of the output shafts of the two first drive motors 32 are respectively connected to the two first rotating shafts. The other end of 11 is fixedly connected, and the surfaces of the two first bidirectional lead screws 4 are threaded with two first threaded blocks 14. The tops of the two first threaded blocks 14 are fixedly connected with clamping plates 7. On one side of the clamping plates 7, multiple sets of semi-circular clamps 35 are arranged in descending order of size. The semi-circular clamps 35 adopt a multi-level nested structure. The clamping plates 7 and the multiple sets of semi-circular clamps 35 are all provided with slots 34. The small semi-circular clamps 35 are slidably connected to the inner wall of the larger semi-circular clamps 35 on the upper layer through the slots 34. The top of the base plate 1 is located near the sides. Each of the two sections has a first through slot 12, and an L-shaped plate 15 is slidably connected within each of the two first through slots 12. A connecting plate 13 is fixedly connected to the top of each of the two L-shaped plates 15. A vertical plate 23 and a fixed plate 8 are fixedly connected to the surfaces of the two connecting plates 13 near their respective sides. A third bearing 24 is fixedly inserted through one side of the vertical plate 23. A third rotating shaft 25 is rotatably connected within the third bearing 24. A second lead screw 26 is fixedly connected to the other end of the third rotating shaft 25. A second threaded block 27 is threadedly connected to the surface of the second lead screw 26. A third drive motor 33 is fixedly connected to one side. The other end of the output shaft of the third drive motor 33 is fixedly connected to the other end of the third rotating shaft 25. The top and bottom of the threaded block and the fixed plate 8 are movably connected by pins to movable rods 9. Two sets of movable rods 9 are movably connected by pins. An extension plate 31 is fixedly connected to one side of the connecting plate 13. One set of movable rods 9 is movably connected to one side of the extension plate 31 by pins. A second through groove 30 is opened on the top of the extension plate 31. Another set of movable rods 9 is slidably connected in the second through groove 30.

[0025] Specifically, the first drive motor 32 operates, driving the first bidirectional lead screw 4 to rotate via the first rotating shaft 11, thereby causing the two first threaded blocks 14 and the two clamping plates 7 to move towards each other. The semi-circular clamps 35 on the clamping plates 7 adopt a multi-level nested structure, with the small clamps sliding into the inner wall of the large clamps via the slots 34, which can adaptively clamp irregularly shaped iron accessories. The third drive motor 33 operates, driving the second lead screw 26 to rotate via the third rotating shaft 25, thereby causing the second threaded block 27 to move. With the help of the pin and the movable rod 9 and the sliding action of another set of movable rods 9 in the second through slot 30, the connecting plate 13 and the two clamping plates 7 can be moved, which facilitates the adjustment of the relative position of the two iron accessories and allows for welding at different welding points.

[0026] Please refer to Figure 1 to Figure 4 A rack 16 is fixedly connected to one side of each of the two L-shaped plates 15. A connecting frame 36 is fixedly connected to the bottom of the base plate 1. A second bearing 19 is fixedly connected to the inner wall of the connecting frame 36. A second rotating shaft 18 is rotatably connected inside the second bearing 19. A gear 17 is fixedly connected to the top of the second rotating shaft 18. The gear 17 meshes with the two racks 16 respectively. A second drive motor 20 is fixedly connected to the bottom of the connecting frame 36. The other end of the output shaft of the second drive motor 20 is fixedly connected to the other end of the second rotating shaft 18.

[0027] Specifically, the second drive motor 20 operates, thereby driving the gear 17 to rotate. With the meshing of the gear 17 with the two racks 16, the two L-shaped plates 15 and the two connecting plates 13 move towards each other, allowing the two iron accessories to come into contact.

[0028] Please refer to Figure 1 to Figure 5 Both sides of the inner wall of the groove 3 are provided with sliding grooves 5, and a first slider 6 is slidably connected in the sliding groove 5. The first slider 6 is fixedly connected to one side of the first threaded block 14. Both sides of the two connecting plates 13 are provided with sliding grooves 29, and a second slider 28 is slidably connected in the sliding grooves 29. The second slider 28 is fixedly connected to one side of the second slider 28. Support rods 21 are fixedly connected to the bottom of the base plate 1 near the four corners, and a base 22 is fixedly connected to the bottom of the support rods 21.

[0029] Specifically, by opening the slide groove 5 and the slide groove 29, the sliding action of the first slider 6 and the second slider 28 in the slide groove 5 and the slide groove 29 respectively can make the first threaded block 14 and the second threaded block 27 move more smoothly.

[0030] In use, the iron attachments are first placed in a series of semi-circular clamps 35 arranged from large to small on one side of the clamping plate 7. The semi-circular clamps 35 adopt a multi-level nested structure. The small semi-circular clamps 35 are slidably connected to the inner wall of the upper-level large semi-circular clamps 35 through the slots 34 opened in the clamping plate 7, which can adaptively clamp irregularly shaped iron attachments. The first drive motor 32 on one side of the two slide plates 2 is activated. The output shaft of the first drive motor 32 drives the first rotating shaft 11 to rotate. The first rotating shaft 11 drives the first bidirectional lead screw 4 to rotate, so that the first threaded blocks 14 connected to the surfaces of the two first bidirectional lead screws 4 drive the clamping plate 7 to move towards each other. The iron attachments are clamped by the semi-circular clamps 35 on the clamping plate 7. If it is necessary to adjust the relative position of the two iron attachments for welding different welding points, the first drive motor 32 on one side of the upright plate 23 can be activated. The third drive motor 33, with its output shaft, drives the third rotating shaft 25 to rotate. The third rotating shaft 25 then drives the second lead screw 26 to rotate, causing the second threaded block 27, which is threaded to the surface of the second lead screw 26, to move. The second threaded block 27 is connected to the top and bottom of the fixed plate 8 via a pin-connected movable rod 9, and two sets of movable rods 9 are connected via pins. This, combined with the second through slot 30 opened at the top of the extension plate 31 on one side of the connecting plate 13, allows another set of movable rods 9 to slide within the second through slot 30, moving the connecting plate 13 and the clamping plate 7 to adjust their positions. If it is necessary to bring the two iron accessories into contact, the second drive motor 20 at the bottom of the connecting frame 36 can be activated. The output shaft of the second drive motor 20 drives the second rotating shaft 18 to rotate, causing the gear 17 at the top of the second rotating shaft 18 to rotate. The gear 17 meshes with the rack 16 on one side of the two L-shaped plates, causing the L-shaped plates to slide within the first through slot 12 at the top of the base plate 1. This, in turn, moves the connecting plate 13 at the top of the L-shaped plates, bringing the two iron accessories into contact for welding.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
