Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for steel beam processing, specifically a steel beam welding auxiliary positioning device. Background Technology

[0002] In the steel structure manufacturing process, steel beam welding is one of the core processes, and its welding quality directly affects the overall load-bearing capacity of the steel structure.

[0003] Traditional supports are mostly fixed structures, which cannot achieve the rotation or multi-angle tilting of steel beams. When welding non-top surface welds such as the side and bottom of the steel beam, manual lifting equipment is required to flip the steel beam multiple times. This is not only cumbersome, time-consuming and labor-intensive, but also prone to causing the steel beam to shift due to collisions during the flipping process, affecting the welding accuracy. At the same time, insufficient positioning and clamping force can easily cause the steel beam to shift during the welding process, resulting in misalignment of the weld. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a steel beam welding auxiliary positioning device, which effectively solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel beam welding auxiliary positioning device, including a base, with foot pads fixedly connected to the four corners of the bottom end of the base, a first cavity opened inside the base, a driving mechanism provided in the first cavity, rectangular holes opened on both sides of the top end of the base, a U-shaped frame fixedly connected to both sides of the top end of the base, an annular shell rotatably connected inside the U-shaped frame, a clamping mechanism provided on one side of the annular shell, and a first rotating wheel fixedly connected to the outer side of the annular shell.

[0006] Preferably, the driving mechanism includes a motor, which is fixedly connected to the inner wall of the first cavity. A transmission rod is fixedly connected to the output end of the motor. One end of the transmission rod is rotatably connected to the inner wall of the first cavity. Second rotating wheels are fixedly sleeved on both sides of the transmission rod. A belt is connected to the outside of the second rotating wheel and the first rotating wheel. The belt is located in a rectangular hole.

[0007] Preferably, the clamping mechanism includes a support frame, which is fixedly installed on one side of the annular shell. A second cavity is provided inside the support frame. A rotating screw is mounted on the inner wall of the second cavity. A worm wheel is fixedly sleeved on the upper side of the outer side of the screw. A worm is rotatably connected to the inner wall of the second cavity. One end of the worm extends through to the outside of the support frame and is fixedly connected to a knob. The worm and the worm wheel are compatible.

[0008] Preferably, the lead screw is externally threaded with an L-shaped block, one side of which extends through to the outside of the support frame, and a limiting hole is provided on one side of the support frame, with the L-shaped block slidably disposed within the limiting hole.

[0009] Preferably, a clamping plate is fixedly connected to the bottom end of the L-shaped block, and telescopic rods are fixedly connected to both sides of the top end of the clamping plate. The top end of the telescopic rods is fixedly connected to the upper wall inside the annular shell.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a motor to drive a transmission rod to rotate, which in turn drives two second rotating wheels to rotate. The two second rotating wheels then drive two first rotating wheels to rotate via belts. The two first rotating wheels then drive two annular shells to rotate, enabling stepless speed regulation of the annular shells. The rotation is smooth and without jamming, and multi-sided welding can be completed without manually flipping the steel beam, greatly reducing operation time and improving welding efficiency. 2. This new type of mechanism uses a rotating knob to drive the worm gear to rotate, which in turn drives the matching worm wheel to rotate. The worm wheel then drives the lead screw to rotate, which in turn drives the threaded L-shaped block to move downwards. The L-shaped block then drives the clamping plate to move downwards, while simultaneously extending the telescopic rod. This allows the clamping plate to clamp the steel beam downwards with uniform clamping force and a self-locking advantage, effectively preventing the steel beam from shifting.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Example 1, by Figures 1-4 The present invention includes a base 1, with foot pads 2 fixedly connected to the four corners of the bottom of the base 1. A first cavity 3 is formed inside the base 1, and a drive mechanism 4 is provided inside the first cavity 3. Rectangular holes 5 are formed on both sides of the top of the base 1. A U-shaped frame 6 is fixedly connected to both sides of the top of the base 1. An annular shell 7 is rotatably connected inside the U-shaped frame 6. A clamping mechanism 8 is provided on one side of the annular shell 7. A first rotating wheel 9 is fixedly connected to one side of the outer side of the annular shell 7. The drive mechanism 4 includes a motor 401, which is fixedly connected to the inner wall of the first cavity 3. A transmission rod 402 is fixedly connected to the output end of the motor 401. One end of the transmission rod 402 is rotatably connected to the inner wall of the first cavity 3. A second rotating wheel 403 is fixedly sleeved on both sides of the outer side of the transmission rod 402. A belt 10 is connected to the outer side of the second rotating wheel 403 and the first rotating wheel 9. The belt 10 is located inside the rectangular hole 5.

[0015] Through the cooperation of the second rotating wheel 403 and the belt 10, the rotational power of the transmission rod 402 is converted into the movement of the belt 10, which in turn drives the first rotating wheel 9 to rotate. At the same time, the second rotating wheels 403, which are symmetrically arranged on both sides, can ensure the balance of force on the belt 10 and the synchronicity of the rotation of the annular shell 7.

[0016] The clamping mechanism 8 includes a support frame 801, which is fixedly installed on one side of the annular shell 7. A second cavity 802 is formed inside the support frame 801. A lead screw 803 rotates on the inner wall of the second cavity 802. A worm gear 804 is fixedly sleeved on the upper side of the lead screw 803. A worm 805 is rotatably connected to the inner wall of the second cavity 802. One end of the worm 805 extends through to the outside of the support frame 801 and is fixedly connected to a knob 806. The worm 805 and the worm gear 804... 04. The lead screw 803 is externally threaded with an L-shaped block 807. One side of the L-shaped block 807 extends through to the outside of the support frame 801. A limit hole 810 is opened on one side of the support frame 801. The L-shaped block 807 is slidably disposed in the limit hole 810. A clamping plate 808 is fixedly connected to the bottom end of the L-shaped block 807. Telescopic rods 809 are fixedly connected to both sides of the top end of the clamping plate 808. The top end of the telescopic rods 809 is fixedly connected to the upper wall inside the annular shell 7.

[0017] The limiting hole 810 can restrict the L-shaped block 807 from rotating with the lead screw 803, ensuring that the L-shaped block 807 only moves in a straight line in the vertical direction, providing guidance for the stable lifting and lowering of the clamping plate 808. The extension and retraction direction of the telescopic rod 809 is consistent with the lifting and lowering direction of the clamping plate 808, which can provide auxiliary support for the clamping plate 808, preventing the clamping plate 808 from tilting due to unilateral force during clamping, and ensuring the flatness of clamping.

[0018] Working principle: In use, the two steel beams to be welded are placed into the two annular shells 7 and aligned in the center. Rotating the knob 806 drives the worm gear 805 to rotate, which in turn drives the matching worm wheel 804 to rotate. The worm wheel 804 drives the lead screw 803 to rotate, which in turn drives the threaded L-shaped block 807 to move downward. The L-shaped block 807 drives the clamping plate 808 to move downward. At the same time, the extension rod 809 extends, which can drive the clamping plate 808 to clamp the steel beams downward. Then, the two steel beams are welded by external welding equipment. The rotation of the motor 401 drives the transmission rod 402 to rotate, which in turn drives the two second rotating wheels 403 to rotate. The two second rotating wheels 403 drive the two first rotating wheels 9 to rotate through the belt 10. The two first rotating wheels 9 drive the two annular shells 7 to rotate, which can realize stepless speed regulation of the rotation of the annular shells 7 for rotary welding of the two steel beams.
