Description

Technical Field

[0001] This invention relates to the field of welding auxiliary device technology, specifically a drive device for a steel section turning mechanism for welding. Background Technology

[0002] H-beam assemblies mainly consist of a web and two flanges. Welding the web and flanges requires flipping the H-beam to weld the other side or other auxiliary components (connecting plates, stiffening plates, etc.). However, when using overhead cranes to lift the H-beams, the beams wobble during the flipping process. This necessitates repeated manual positioning during welding of auxiliary components, leading to inconsistent results and low production efficiency. Furthermore, using overhead cranes for assisted operation is not only inefficient but also increases the risk of safety accidents.

[0003] However, the commonly used H-beam turning equipment has a fixed and rigid position, making it inconvenient to adjust the clamping range according to different models of H-beams, thus limiting its applicability. Summary of the Invention

[0004] The purpose of this invention is to provide a driving device for a steel section turning mechanism for welding, which aims to solve the problem that existing H-beam turning equipment has a fixed and rigid position, making it inconvenient to adjust the clamping range according to different types of H-beams, and thus has a limited range of applications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the driving device of the welding steel section turning mechanism includes two symmetrically arranged frames, a rotating seat is rotatably mounted on the frame, two pairs of clamping rods are mounted on the rotating seat, a driving device for driving the rotating seat to rotate is mounted on the frame, a motion device for controlling the movement of the two pairs of clamping rods on the same vertical plane is installed inside the rotating seat, and a control device for controlling the extension and retraction of the two clamping rods located above is mounted on the rotating seat.

[0006] A further technical solution of the present invention is that the driving device includes a gear ring fixedly installed on the circumferential surface of the rotating seat, a gear meshing on the gear ring, a motor installed on the frame, and the output end of the motor connected to the gear.

[0007] A further technical solution of the present invention is that the motion device includes two adjustment mechanisms for adjusting the distance between two clamping rods in each pair of clamping rods and a clamping mechanism for adjusting the distance between the two pairs of clamping rods.

[0008] A further technical solution of the present invention is that the adjusting mechanism includes a sliding groove, two sliders are slidably installed in the sliding groove, the clamping rod is installed on the slider, and connecting rods are hinged to both sliders. A hydraulic rod is installed on the sliding groove, and a moving plate is installed at the other end of the hydraulic rod. The other ends of the two connecting rods are hinged to the moving plate.

[0009] A further technical solution of the present invention is that the clamping mechanism includes two bidirectional lead screws rotatably mounted on a rotating seat, a transmission mechanism is installed between the two bidirectional lead screws, and nuts are provided at both ends of the sliding groove, with the two nuts respectively engaging with the two bidirectional lead screws.

[0010] A further technical solution of the present invention is that the transmission mechanism includes a sprocket mounted on a bidirectional lead screw, and two sprockets at the same end are connected by a chain drive. A drive component for driving the sprocket to rotate is mounted on the rotating seat.

[0011] A further technical solution of the present invention is that the driving component is a servo motor, and the output end of the servo motor is connected to one of the bidirectional lead screws.

[0012] A further technical solution of the present invention is that the control device is disposed on the back plate on the back of the rotating seat, the back plate is fixedly installed on the frame, the back plate has an opening, the projection of the opening on the rotating seat is located in the upper half of the rotating seat, a push-pull plate is disposed in the opening, a moving component for controlling the movement of the push-pull plate is installed on the back plate, the clamping rod is slidably mounted on the slider, the end of the clamping rod near the back plate is magnetic, and the clamping rod can be attracted to the push-pull plate under the action of magnetic force.

[0013] A further technical solution of the present invention is that the moving part is a hydraulic cylinder, and the two ends of the hydraulic cylinder are respectively connected to the push-pull plate and the back plate.

[0014] In order to reduce the frictional force on the clamping rod, a further technical solution of the present invention is that a ball bearing is provided at the end of the clamping rod near the back plate.

[0015] The beneficial effects of this invention are:

[0016] 1. When using this invention, the distance between the four clamping rods is adjusted by the motion device, so that the four clamping rods can abut against the four right angles of the H-beam, thus fixing it firmly. It can be adjusted according to different models of H-beams, and has a wide range of applications. The two upper clamping rods can be extended and retracted by the control device, which facilitates the replacement of H-beams.

[0017] 2. When using this invention, since the projection of the opening on the rotating seat is located in the upper half of the rotating seat, when the two diagonally opposite clamping rods are not at the same height, the push-pull plate moves through magnetic force to drive the two clamping rods located above to move, thereby facilitating the assembly and disassembly of H-beams.

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a drive device for a steel section turning mechanism for welding includes two symmetrically arranged frames. The distance between the two frames can be adjusted by a motion mechanism. A rotating seat 1 is rotatably mounted on the frame, and two pairs of clamping rods 2 are mounted on the rotating seat 1. A drive device 3 for driving the rotating seat 1 to rotate is mounted on the frame. A motion device 4 for controlling the movement of the two pairs of clamping rods 2 on the same vertical plane is installed inside the rotating seat 1. A control device 5 for controlling the extension and retraction of the two upper clamping rods 2 is mounted on the rotating seat 1. By controlling the extension and retraction of the two upper clamping rods 2 through the control device 5, it is convenient to replace the H-beam.

[0026] In this specific embodiment, the distance between the four clamping rods 2 is adjusted by the motion device 4, so that the four clamping rods 2 can abut against the four right angles of the H-beam, thereby fixing it firmly. It can be adjusted according to different models of H-beams and has a wide range of applications.

[0027] Specifically, the drive device 3 includes a gear ring 31 fixedly mounted on the circumferential surface of the rotating seat 1, a gear 32 meshing on the gear ring 31, a motor 33 mounted on the frame, and the output end of the motor 33 connected to the gear 32. Starting the motor 33 causes the gear 32 to rotate, thereby causing the gear ring 31 to rotate, which in turn causes the rotating seat 1 to rotate with the clamping rod 2, thereby causing the H-beam to rotate.

[0028] Specifically, the motion device 4 includes two adjustment mechanisms 41 that adjust the distance between the two clamping rods 2 in each pair of clamping rods 2 respectively, and a clamping mechanism 42 that adjusts the distance between the two pairs of clamping rods 2.

[0029] Specifically, the adjusting mechanism 41 includes a sliding groove 411, in which two sliders 412 are slidably installed. Clamping rods 2 are installed on the sliders 412, and connecting rods 413 are hinged to both sliders 412. A hydraulic rod 414 is installed on the sliding groove 411, and a moving plate 415 is installed at the other end of the hydraulic rod 414. The other ends of the two connecting rods 413 are hinged to the moving plate 415. When the hydraulic rod 414 is activated, the moving plate 415 moves relative to the sliding groove 411, thereby causing the other end of the connecting rod 413 to slide along the sliding groove 411 with the sliders 412, thereby causing the two clamping rods 2 to move closer to or further away from each other.

[0030] Specifically, the clamping mechanism 42 includes two bidirectional lead screws 421 rotatably mounted on the rotating seat 1, a transmission mechanism 422 is installed between the two bidirectional lead screws 421, and nuts 423 are provided at both ends of the sliding groove 411. The two nuts 423 respectively mesh with the two bidirectional lead screws 421, and the nuts 423 on the two sliding grooves 411 respectively mesh with two threaded sections with opposite directions of rotation on the bidirectional lead screws 421.

[0031] Specifically, the transmission mechanism 422 includes a sprocket 4221 mounted on a bidirectional lead screw 421. The two sprockets 4221 at the same end are connected by a chain 4222. A drive component for driving the sprockets to rotate is mounted on the rotating seat 1. The sprocket 4221 and the chain 4222 can also be replaced by gears and flexible racks.

[0032] Specifically, the driving component is a servo motor 4223. The output end of the servo motor 4223 is connected to one of the bidirectional lead screws 421. The servo motor 4223 causes the sprocket 4221 to rotate, thereby causing the two bidirectional lead screws 421 to rotate synchronously through the chain 4222, so that the nut, along with the two sliding grooves 411, moves closer or further apart.

[0033] Specifically, the control device 5 is located on the back plate 51 on the back of the rotating seat 1. The back plate 51 is fixedly mounted on the frame. An opening is provided on the back plate 51. The projection of the opening on the rotating seat 1 is located in the upper half of the rotating seat 1. A push-pull plate 52 is provided in the opening. A moving part 53 for controlling the movement of the push-pull plate 52 is installed on the back plate 51. The clamping rod 2 is slidably mounted on the slider 412. The end of the clamping rod 2 near the back plate 51 is magnetic. The clamping rod 2 can be attracted to the push-pull plate 52 under the action of magnetic force. A ball or roller is provided at the end of the clamping rod 2 near the back plate 51. The ball reduces the friction between the clamping rod 2 and the back plate 51 and the push-pull rod 52 when the clamping rod 2 moves. The upper half of the pattern formed by all the movement paths of the clamping rod 2 overlaps with the opening on the back plate 51, so it is convenient to take out when the H-beam is deflected, and convenient to remove and put in after tilting welding.

[0034] Specifically, the moving part 53 is a hydraulic cylinder. The two ends of the hydraulic cylinder 53 are connected to the push-pull plate 52 and the back plate 51 respectively. Activating the hydraulic cylinder causes the push-pull plate 52 to move, thereby moving the two upper clamping rods of the four clamping rods 2, which facilitates the removal or placement of H-beams from above.
