Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tool for welding and assembling multi-angle profiles. Background Technology

[0002] In welding repair, steel structure processing and building construction, it is often necessary to fix the workpiece at a precise right angle. In special cases, there are different angle fixing requirements, and the welding and assembly of multi-angle profiles is a common and important process.

[0003] Currently, adjustable-angle clamping arms combined with threaded rods are commonly used to clamp and fix workpieces in different positions and shapes. However, during long-term use, this traditional threaded rod clamping structure is prone to reverse rotation due to the vibration, impact, and other external forces that often accompany the welding or assembly of the workpiece. The mating surfaces of the threaded rod and the threaded hole will experience slight relative movement due to continuous force. This reverse rotation of the threaded rod will directly lead to a decrease in the clamping force between it and the workpiece, causing the workpiece to loosen. Loosening of the workpiece will not only damage the positioning accuracy of the workpiece, but in severe cases, it may even cause the workpiece to shift or fall off during processing, reducing the stability of the workpiece during processing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a tool for welding and assembling multi-angle profiles, comprising:

[0030] The assembly includes a support plate 11, a clamping arm 12, an internal threaded ring 13, a threaded rod 14, and a handle 15. The clamping arm 12 is fixed to one side of the support plate 11, the internal threaded ring 13 is disposed in the middle of one side of the clamping arm 12, the threaded rod 14 is threadedly connected to the middle of the internal threaded ring 13, and the handle 15 is fixedly connected to the outside of the threaded rod 14.

[0031] Rotating the handle 15 transmits the rotational motion of the handle 15 to the threaded rod 14, driving the threaded rod 14 to move along its axial direction. The end of the threaded rod 14 gradually approaches the workpiece and eventually presses against the workpiece, using the pressure between the threaded rod 14 and the workpiece to clamp and fix the workpiece.

[0032] The reinforcing component includes a support frame 31, a positioning groove 32, a vertical plate 35, a top block 36, a positioning block 37, a limiting block 39, and a top plate 391. The support frame 31 is located at the top and bottom of the clamping arm 12. The top plate 391 is fixed to one side of the support frame 31. The vertical plate 35 is movably connected through the interior of the top plate 391. The top block 36 is located on one side of the top plate 391. The limiting block 39 is located on the other side of the top plate 391. The positioning block 37 is located at the bottom of the top block 36. The positioning groove 32 is opened on the outer surface of the handle 15. The positioning block 37 is inserted into the interior of the positioning groove 32.

[0033] Push the support frame 31 so that the positioning block 37 on the support frame 31 is aligned and inserted into the positioning groove 32 corresponding to the handle 15. The mechanical cooperation between the positioning block 37 and the positioning groove 32 limits the handle 15 and prevents the handle 15 from reversing, thereby ensuring that the clamping force between the threaded rod 14 and the workpiece remains stable.

[0034] The top and bottom of the clamping arm 12 are provided with movable grooves 33, and the bottom of the support frame 31 is movably connected to the inside of the movable grooves 33;

[0035] The support frame 31 can move horizontally along the movable groove 33.

[0036] Both ends of the inner surface of the movable groove 33 are provided with sliding grooves 34, and both ends of the support frame 31 are provided with sliders 38, which are movably connected to the sliding grooves 34.

[0037] The slider 38 at the bottom of the support frame slides into the groove 34 to ensure that the support frame 31 moves smoothly.

[0038] It also includes an adjustment component, which includes a rotating rod 21 and a rotating ring 22. The two rotating rings 22 are respectively sleeved on both ends of the outer surface of the rotating rod 21, and the support plates 11 are respectively connected to one side of the rotating rings 22.

[0039] Both the front rotating ring 22 and the rear rotating ring 22 are movably sleeved on the outside of the rotating rod 21. The rotating ring 22 can rotate freely around the rotating rod 21, thereby driving the clamping arm 12 to rotate synchronously.

[0040] The two ends of the outer surface of the rotating rod 21 are fixedly connected to the limiting disk 23. The outer end of the rotating rod 21 is provided with a guide rod 24. The guide rod 24 is movably connected between the rotating ring 22 and the limiting disk 23. The outer surface of the guide rod 24 is threaded with a fastening ring 25.

[0041] During the rotation of the rotating ring 22, the guide rod 24 moves between the rotating ring 22 and the limiting plate 23 to coordinate with the angle adjustment of the rotating ring 22. When the clamping arm 12 rotates to the angle that matches the workpiece, the fastening ring 25 is screwed and fastened to the outside of the guide rod 24. The squeezing force between the fastening ring 25 and the rotating ring 22 and the limiting plate 23 restricts the rotation of the rotating ring 22, thereby fixing the angle of the clamping arm 12.

[0042] Working principle:

[0043] First, both the front and rear rotating rings 22 are movably sleeved on the outside of the rotating rod 21. The rotating rings 22 can rotate freely around the rotating rod 21, thereby driving the clamping arm 12 to rotate synchronously. Meanwhile, the guide rod 24 moves between the rotating rings 22 and the limiting plate 23. Next, the fastening ring 25 is screwed and fastened to the outside of the guide rod 24. After the angle of the clamping arm 12 is adjusted, the handle 15 is rotated. The rotational movement of the handle 15 is transmitted to the threaded rod 14. The pressure between the threaded rod 14 and the workpiece is used to clamp and fix the workpiece.

[0044] Next, push the support frame 31 so that the positioning block 37 on the support frame 31 is aligned and inserted into the positioning groove 32 corresponding to the handle 15. In addition, the upright plate 35 can slide up and down inside the top plate 391. The height position of the positioning block 37 can be changed by adjusting the height of the upright plate 35.

[0045] This step enables flexible adjustment and fixation of the clamping arm angle 12, reliable clamping of the workpiece, and anti-reverse locking, ensuring the stability of the workpiece during processing.

[0046] Please see Figure 1 , Figure 5 As shown, this embodiment, based on the above embodiment, further includes:

[0047] The locking component includes a base 41, a damping rod 42, a limiting ring 43, and a damping ring 46. The base 41 is fixed to the middle of the outer side of the handle 15. The damping rod 42 is disposed on the outer surface of the base 41. The damping ring 46 is sleeved on the outside of the damping rod 42. The limiting ring 43 is fixed on the outside of the damping rod 42.

[0048] After the positioning block 37 is inserted into the positioning groove 32, the damping ring 46 can move outside the damping rod 42, surrounding the locking frame 45 around the top block 36. Due to the friction between the damping ring 46 and the damping rod 42, the locking frame 45 can stably surround the top block 36, limiting the displacement of the top block 36 in all directions, thereby preventing the top block 36 from becoming loose. Even if there are external forces such as vibration during the welding process, the surrounding effect of the locking frame 45 on the top block 36 can effectively counteract the external forces, ensuring a stable fit between the positioning block 37 and the positioning groove 32.

[0049] A horizontal plate 44 is fixedly connected to the outer surface of the damping ring 46, and a locking frame 45 is fixedly connected to the outside of the horizontal plate 44. The locking frame 45 is snapped onto the outside of the top block 36.

[0050] Working principle:

[0051] After the positioning block 37 is inserted into the positioning groove 32, the operator pushes the damping ring 46 along the damping rod 42 toward the top block 36, causing the locking frame 45 to move synchronously until the locking frame 45 completely surrounds the outside of the top block 36.

[0052] This step further enhances the reliability of the entire clamping and fixing device, effectively copes with vibration interference under welding and other working conditions, and ensures the stability of workpiece clamping.
