Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and in particular to a welding mechanism for a welding machine. Background Technology

[0002] A welding machine is an industrial device that uses physical or chemical means to heat two or more metal materials to a molten state in a localized area and then pressurize or fill them with materials to form a permanent connection. The positioning function of the welding mechanism ensures the stability of the parts during welding.

[0003] In existing technologies, welding mechanisms commonly use clamps to hold and fix components during welding operations, ensuring their stability during welding. While this fixing method is simple and easy to operate, the component's position is usually fixed after fixing, lacking a flexible adjustment mechanism. Because the component's position is not adjustable, when welding the bottom area of ​​a part, the space in that area is relatively narrow, making it difficult for the operating parts of the welding equipment (such as welding torches and welding heads) to easily extend, thus preventing direct welding of the bottom. In this case, it is necessary to remove the clamped component from the welding mechanism, readjust the clamping position or angle to expose the bottom in a space suitable for welding, and then perform a second clamping and welding operation. For large-scale welding operations, repeated clamping not only increases additional operating steps and time costs but also makes the entire welding workflow cumbersome and inefficient. Therefore, it is necessary to improve the welding mechanism of a welding machine to solve the above problems. Utility Model Content

[0004] To overcome the problem that positioning parts with clamps results in the parts' angles being unadjustable, and that parts need to be re-clamped when welding the bottom of the parts.

[0005] The technical solution of this utility model is as follows: a welding mechanism for a welding machine, including a mounting base, a T-shaped worktable, and a welding machine body, and further including a first upright plate and a mounting mechanism. The T-shaped worktable is disposed at the bottom of the mounting base and is fixedly connected to the welding machine body. The mounting base is provided with a mounting mechanism connecting the mounting base and the T-shaped worktable. The first upright plate is fixedly connected to the top of the mounting base. A rotating shaft is rotatably connected to the upper part of the first upright plate. A first rubber pad is fixedly connected to the left side of the rotating shaft. A second upright plate is fixedly connected to the top of the mounting base. A limiting rotating sleeve is rotatably connected inside the second upright plate. A first threaded rod is slidably connected inside the limiting rotating sleeve. A mounting plate that cooperates with the rotating shaft to clamp parts is fixedly connected to the right side of the first threaded rod. A second rubber pad that increases friction between the mounting plate and the parts is fixedly connected to the right side of the mounting plate.

[0006] Preferably, the limiting rotating sleeve has a through hole inside, and the first threaded rod has a matching groove at the corresponding position of the through hole, and the first threaded rod slides inside the through hole through the groove.

[0007] Preferably, the first upright plate and the second upright plate have limit grooves at corresponding positions of the rotating shaft and the limiting rotating sleeve, and the rotating shaft and the limiting rotating sleeve rotate inside the limit grooves of the first upright plate and the second upright plate, respectively.

[0008] Preferably, a positioning block is fixedly connected to the right side of the second vertical plate, a worm gear is rotatably connected to the positioning block, a worm wheel is meshed on the worm gear, the worm wheel is fixedly connected to the right side of the limiting rotating sleeve, a limiting ring is rotatably connected to the limiting rotating sleeve, and a first hexagonal nut that allows the first threaded rod to slide is fixedly connected to the left side of the limiting ring, the first hexagonal nut being threaded onto the first threaded rod.

[0009] Preferably, the limiting rotating sleeve has a limiting hole at the corresponding position of the limiting ring, and the limiting ring rotates inside the limiting hole.

[0010] Preferably, the mounting mechanism includes a rotating block, which is rotatably connected to the mounting base. A second hexagonal nut is rotatably connected to the top of the rotating block, and a second threaded rod is threaded onto the second hexagonal nut. A clamping plate that is snapped onto the T-shaped worktable is fixedly connected to the bottom of the second threaded rod.

[0011] Preferably, the mounting base has a movable groove at the corresponding position of the rotating block, and the rotating block is disposed inside the movable groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. The mounting plate, in conjunction with the rotating shaft, clamps the parts to be welded. The second rubber pad increases the friction between the parts and the rotating shaft, effectively ensuring the stability of the parts and preventing slippage. The sliding of the first threaded rod can be flexibly adjusted according to the size of the parts, clamping parts of different sizes. The rotation of the limiting rotating sleeve drives the first threaded rod to rotate, which, in conjunction with the rotation of the rotating shaft, causes the clamped parts to flip over, turning the original bottom surface upwards for welding. No re-clamping is required, making it highly efficient and not delaying the processing progress, thus effectively improving processing efficiency.

[0014] 2. The second threaded rod can be inserted into the T-slot of the T-shaped worktable by means of the flip-up rotating block. Then, the clamping plate can be rotated to lock it in the T-slot, which can quickly locate the position of the mounting base without removing the second threaded rod, thus avoiding the second threaded rod being lost or not being found.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of a welding mechanism for a welding machine, including a mounting base 1, a T-shaped worktable 4, and a welding machine body 5. It also includes a first upright plate 21 and a mounting mechanism. The T-shaped worktable 4 is disposed at the bottom of the mounting base 1 and is fixedly connected to the welding machine body 5. The mounting base 1 is provided with a mounting mechanism connecting the mounting base 1 and the T-shaped worktable 4. The first upright plate 21 is fixedly connected to the top of the mounting base 1. A rotating shaft 22 is rotatably connected to the upper part of the first upright plate 21. A first rubber pad 23 is fixedly connected to the left side of the rotating shaft 22. A second upright plate 24 is fixedly connected to the top of the mounting base 1. A limiting rotating sleeve 25 is rotatably connected inside the second upright plate 24. A first threaded rod 26 is slidably connected inside the limiting rotating sleeve 25. A mounting plate 27 for clamping components, which cooperates with the rotating shaft 22, is fixedly connected to the right side of the first threaded rod 26. An enlargement and a zeroing mechanism are fixedly connected to the right side of the mounting plate 27. The second rubber pad 28, which causes friction between components, is used to mount the mounting base 1 on the top of the T-shaped worktable 4 via the mounting mechanism. The mounting base 1 is then positioned, and the component to be welded is placed between the mounting plate 27 and the rotating shaft 22. The first threaded rod 26 slides inside the limiting rotating sleeve 25, driving the mounting plate 27. The mounting plate 27 abuts against the component via the second rubber pad 28. The second rubber pad 28 increases the friction between the mounting plate 27 and the rotating shaft 22 on the component by the first rubber pad 23. The component is then fixed by the mounting plate 27 and the rotating shaft 22. Welding is then performed by the welding machine body 5. Rotating the limiting rotating sleeve 25 drives the first threaded rod 26 to rotate, which in turn drives the mounting plate 27, thereby causing the component to rotate. The component causes the rotating shaft 22 to rotate as well. The welding machine body 5 is a commonly used technique in this field, so it will not be described in detail.

[0023] Please see Figures 1-4In this embodiment, the limiting rotating sleeve 25 has a through hole inside, and the first threaded rod 26 has a matching groove at the corresponding position of the through hole. The first threaded rod 26 slides inside the through hole through the groove. The through hole and the first threaded rod 26 with the groove cooperate, so that the first threaded rod 26 can be rotated while the limiting rotating sleeve 25 rotates. This allows the component to be rotated without disassembling the component, and the angle can be adjusted. The first upright plate 21 and the second upright plate 24 have limiting grooves at the corresponding positions of the rotating shaft 22 and the limiting rotating sleeve 25, and the rotating shaft 22 and the limiting rotating sleeve 25 are respectively on the first upright plate 21 and the second upright plate 24. The limiting sleeve 25 rotates inside the limiting groove, and the limiting groove positions the limiting rotating sleeve 25 and the rotating shaft 22. This ensures stability without affecting the rotation of the rotating shaft 22 and the limiting rotating sleeve 25. A positioning block 29 is fixedly connected to the right side of the second vertical plate 24. A worm gear 210 is rotatably connected to the positioning block 29, and a worm wheel 211 meshes with the worm gear 210. The worm wheel 211 is fixedly connected to the right side of the limiting rotating sleeve 25. A limiting ring 212 is rotatably connected to the limiting rotating sleeve 25. A first hexagonal nut 213, which allows the first threaded rod 26 to slide, is fixedly connected to the left side of the limiting ring 212. 213 is threaded onto the first threaded rod 26. Through the self-locking between the worm 210 and the worm wheel 211, the angle of the component after the positioning angle is adjusted can be positioned to prevent the component from rotating on its own and shifting. Rotating the first hexagonal nut 213 can be appropriately adjusted according to the size of the component to position components of different sizes. The limiting rotating sleeve 25 has a limiting hole at the corresponding position of the limiting ring 212, and the limiting ring 212 rotates inside the limiting hole. The limiting hole makes the limiting ring 212 rotate smoothly, preventing the limiting ring 212 from disengaging and preventing the limiting ring 212 from tilting and getting stuck.

[0024] Please see Figure 1 , Figure 5 In this embodiment, the mounting mechanism includes a rotating block 31, which is rotatably connected to the mounting base 1. A second hexagonal nut 32 is rotatably connected to the top of the rotating block 31, and a second threaded rod 33 is threaded onto the second hexagonal nut 32. A clamping plate 34 that is locked onto the T-shaped worktable 4 is fixedly connected to the bottom of the second threaded rod 33. The rotating block 31 can be rotated to make the second threaded rod 33 tilt up, thereby causing the clamping plate 34 to disengage from the T-shaped worktable 4, thereby disassembling the mounting base 1 and facilitating the transfer of the mounting base 1 and its connected components. The mounting base 1 has a movable groove at the corresponding position of the rotating block 31, and the rotating block 31 is set inside the movable groove. The movable groove avoids path conflict between the rotating block 31 and the mounting base 1, allowing the rotating block 31 to rotate without obstruction.

[0025] During operation, rotating the second threaded rod 33 drives the clamping plate 34, aligning it with the T-slot of the T-shaped worktable 4. Then, rotating the rotating block 31 disengages the clamping plate 34 from the T-shaped worktable 4, allowing the mounting base 1 to be moved. Similarly, during installation, the clamping plate 34 is first misaligned with the T-slot of the T-shaped worktable 4. After rotating the rotating block 31 to insert the clamping plate 34 into the T-slot, rotating the second threaded rod 33 locks the clamping plate 34 into the T-slot. Then, first position the second threaded rod 33, and then tighten the second hexagonal nut 32 to secure the clamping plate 34, thus positioning the mounting base 1. The components can then be placed on the mounting base. Between plate 27 and rotating shaft 22, the first hexagonal nut 213 is twisted. The first hexagonal nut 213 is limited by the limiting ring 212. The rotation of the first hexagonal nut 213 drives the first threaded rod 26 to slide. The first threaded rod 26 drives the mounting plate 27. The mounting plate 27, through the second rubber pad 28, cooperates with the rotating shaft 22 and the first rubber pad 23 to clamp the parts and position them. The worm gear 210 is twisted to drive the worm wheel 211. The worm wheel 211 drives the limiting rotating sleeve 25 to rotate, which in turn drives the first threaded rod 26 to rotate, thereby driving the parts to rotate. The parts will drive the rotating shaft 22 to rotate synchronously, adjusting the angle of the parts.

[0026] Through the above steps, the sliding of the first threaded rod 26 can be flexibly adjusted according to the size of the parts, clamping parts of different sizes. The rotation of the limiting rotating sleeve 25 can drive the first threaded rod 26 to rotate, and in conjunction with the rotation of the rotating shaft 22, the clamped parts can be flipped over. This solves the problem of the clamping plate positioning the parts, which causes the part angle to be unadjustable, and the need to re-clamp the parts when welding the bottom position of the parts.
