Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for handling round tubes, and in particular to a round tube tilting clamp device. Background Technology

[0002] In fields such as machinery manufacturing, construction, and pipeline installation, it is often necessary to handle and tilt round tubes. Currently, tilting round tubes mostly relies on manual labor with simple tools, which is not only labor-intensive and inefficient, but also makes it difficult to accurately control the posture and tilting angle of the tubes during the tilting process, easily leading to collision damage and even safety accidents.

[0003] Traditional clamps suffer from poor adjustment flexibility in their clamping mechanisms, making them unsuitable for round tubes of varying diameters and resulting in low versatility. The lack of stable braking and angle control structures makes it difficult to precisely control the clamp's rotation speed and angle during tube tilting, leading to problems such as excessively rapid tilting or angle deviations, impacting work quality and safety. Furthermore, the clamping parts of traditional clamps are mostly rigid contacts, which can easily scratch or deform the surface of round tubes, especially for workpieces requiring high surface precision, failing to meet protection requirements. Utility Model Content

[0004] The present invention provides a round tube tilting clamp device, which aims to solve the problems of being unable to adapt to round tubes of different diameters, lacking a stable braking and angle control structure, and easily causing scratches or extrusion deformation on the surface of the round tube when clamping it.

The first hydraulic rod is disposed in the placement hole, and the telescopic ends of the two first hydraulic rods are close to the side of the slide groove and connected to the side of the first arc-shaped clamp.

[0007] Furthermore, the upper and lower ends of the first arc-shaped clamp are simultaneously connected to a first limiting block, and the upper and lower ends of the slide groove are simultaneously provided with a first limiting groove for the first limiting block to slide.

[0016] like Figure 1-7As shown, this utility model embodiment provides a round tube tilting clamp device, including a crossbeam 1, a braking component 3, a cross plate 4, a connecting plate 8, a clamping component 10, and a PLC controller 15. One end of the crossbeam 1 is connected to a mobile device, and the other end of the crossbeam 1 is connected to a first servo motor 2. The braking component 3 is disposed around the periphery of the first servo motor 2. One side of the cross plate 4 is connected to the output end of the first servo motor 2, and the other side of the cross plate 4 has a horizontally opened sliding groove 5. A bidirectional threaded rod 6 is rotatably installed in the sliding groove 5, and one end of the bidirectional threaded rod 6 passes through the sliding groove 5 and is connected to a second servo motor 7. Two connecting plates 8 are symmetrically slidably installed in the sliding groove 5 with the intersection of the positive and negative threads of the bidirectional threaded rod 6 as the center. The interior of the two connecting plates 8 has a horizontally penetrating threaded hole 9 that meshes with the bidirectional threaded rod 6. Two clamping assemblies 10 are connected to the ends of the connecting plate 8. The clamping part of the clamping assembly 10 is connected to a second arc-shaped clamping plate 11. The opposite surfaces of the two second arc-shaped clamping plates 11 are provided with placement grooves 12. A rubber pad 13 is provided in the placement groove 12. A fixing assembly 14 is provided between the rubber pad 13 and the side wall of the placement groove 12. The PLC controller 15 is electrically connected to the first servo motor 2, the braking assembly 3, the second servo motor 7, and the clamping assembly 10.

[0017] This utility model provides a cylindrical tube tilting clamp device, which includes a braking component 3 located around a first servo motor 2 to brake the rotation shaft of the first servo motor 2, precisely controlling the rotation angle of the horizontal plate 4 and subsequent components. The rotation of the bidirectional threaded rod 6 allows the two connecting plates 8 to move synchronously closer or further apart, adapting to cylindrical tubes of different specifications. A rubber pad 13 is installed inside the placement groove 12 to buffer the clamping force and protect the surface of the cylindrical tube. A fixing component 14 is installed between the rubber pad 13 and the side wall of the placement groove 12 to ensure stable installation of the rubber pad 13 and facilitate disassembly and replacement.

[0018] like Figure 6As shown in the embodiment of this application, the braking component 3 includes a positioning ring 16, a first arc-shaped clamping plate 19, and a first hydraulic rod 20. The positioning ring 16 is annularly surrounding the rotating shaft of the first servo motor 2. One side of the positioning ring 16 is connected to the end face of the first servo motor 2 near the rotating shaft. The inner sidewall of the positioning ring 16 is symmetrically provided with grooves 17 centered on the rotating shaft of the first servo motor 2. Placement holes 18 are provided on opposite sides of the two grooves 17. The first arc-shaped clamping plate 19 is slidably installed in the two grooves 17, and the inner sidewall of the two first arc-shaped clamping plates 19 is in contact with the outer surface of the rotating shaft of the first servo motor 2. The first hydraulic rod 20 is disposed in the placement hole 18, and the telescopic ends of the two first hydraulic rods 20 are close to the side of the groove 17 and connected to the side of the first arc-shaped clamping plate 19. When braking is required, the PLC controller controls the first hydraulic rod 20 to extend, pushing the first arc-shaped clamping plate 19 along the slide groove 17 toward the rotating shaft and clamping it, thereby braking the rotating shaft through friction.

[0019] like Figure 6 As shown in the embodiment of this application, the upper and lower ends of the first arc-shaped clamping plate 19 are simultaneously connected to the first limiting block 21, and the upper and lower ends of the slide groove 17 are simultaneously provided with the first limiting groove 22 for the first limiting block 21 to slide. The cooperation between the first limiting block 21 and the first limiting groove 22 can prevent the first arc-shaped clamping plate 19 from disengaging from the slide groove 17 during the sliding process, thus ensuring the stability of the braking component 3.

[0020] like Figure 1 As shown in the embodiment of this application, the clamping assembly 10 includes a second hydraulic rod 23, a first fixing plate 24, a second fixing plate 25, a clamping rod 26, and a connecting rod 27. The two hydraulic rods are connected to the ends of the connecting plate 8 away from the telescopic ends. One end of each of the two first fixing plates 24 is connected to the front and rear sides of the main body of the second hydraulic rod 23, respectively. One end of each of the two second fixing plates 25 is connected to the front and rear sides of the telescopic portion of the second hydraulic rod 23, respectively. One end of the clamping rod 26 is hinged to the other end of the first fixing plate 24, and the other end of the clamping rod 26 is connected to the second arc-shaped clamping plate 11. One end of the connecting rod 27 is hinged to the other end of the second fixing plate 25, and the other end of the connecting rod 27 is hinged to the middle part of the clamping rod 26. When the second hydraulic rod 23 extends or retracts, it drives the second fixing plate 25 to move, and pushes the clamping rod 26 to rotate around the hinge point of the first fixing plate 24 through the connecting rod 27, thereby realizing the clamping or releasing action of the second arc-shaped clamping plate 11. The clamping force is stable and easy to adjust.

[0021] like Figure 5As shown in the embodiment of this application, the fixing component 14 includes a round-headed locking block 28 and a telescopic spring 30. The upper and lower ends of the placement groove 12 are simultaneously provided with first slots for the round-headed locking block 28 to slide. The upper and lower ends of the rubber pad 13 are simultaneously provided with semi-circular grooves 29 that engage with the round-headed locking block 28. The telescopic spring 30 is located within the first slot, with one end connected to the side wall of the first slot and the other end connected to the end of the round-headed locking block 28. When installing the rubber pad 13, the round-headed locking block 28 engages with the semi-circular groove 29 under the elastic force of the telescopic spring 30, achieving quick fixing of the rubber pad 13. When it is necessary to replace the rubber pad 13, simply press the round-headed locking block 28 into the first slot to remove the rubber pad 13; the operation is simple and convenient.

[0022] like Figure 5 As shown in the embodiment of this application, second limiting blocks 31 are symmetrically arranged on both sides of the round-headed locking block 28 with the round-headed locking block 28 as the center, and a second limiting groove 32 is opened on the side wall of the first slot for the second limiting blocks 31 to slide. The cooperation between the second limiting blocks 31 and the second limiting groove 32 can prevent the round-headed locking block 28 from coming out of the first slot under the action of the telescopic spring 30, and ensure the structural integrity of the fixing assembly 14.

[0023] The working process of this utility model is as follows: When using this device, one end of the crossbeam 1 is fixedly connected to an external mobile device (such as a crane or robotic arm), and the other end is connected to the housing of the first servo motor 2 by bolts, so as to realize the movement of the entire fixture.

[0024] The braking assembly 3 is sleeved on the outside of the rotating shaft of the first servo motor 2. The positioning ring 16 is fixed to the end face of the first servo motor 2 near the rotating shaft. Two symmetrical sliding grooves 17 are opened on the inner side wall of the positioning ring 16. The first arc-shaped clamping plate 19 is slidably installed in the sliding grooves 17. The inner side wall of the first arc-shaped clamping plate 19 is provided with a rubber pad to enhance the friction with the rotating shaft. The opposite side of the positioning ring 16 has a placement hole 18. The first hydraulic rod 20 is fixed in the placement hole 18. The telescopic end of the first hydraulic rod 20 is connected to the side of the first arc-shaped clamping plate 19 through a pin. When the first servo motor 2 drives the horizontal plate 4 to rotate to the target angle, the PLC controller sends a signal to the first hydraulic rod 20. The first hydraulic rod 20 extends and pushes the first arc-shaped clamping plate 19 to clamp the rotating shaft, achieving precise braking. One side of the horizontal plate 4 is connected to the output end of the first servo motor 2 via a coupling. The other side is milled with a sliding groove 5. A bidirectional threaded rod 6 is rotatably mounted within the sliding groove 5 via a bearing. One end of the bidirectional threaded rod 6 passes through the side wall of the sliding groove 5 and is connected to the output end of the second servo motor 7 via a coupling. The second servo motor 7 is fixed to the side of the horizontal plate 4 with bolts. The bottoms of the two connecting plates 8 are embedded in the sliding groove 5, and threaded holes 9 are formed inside the connecting plates 8 to engage with the bidirectional threaded rod 6. The two threaded holes 9 are respectively adapted to the positive thread section and the negative thread section of the bidirectional threaded rod 6. When the second servo motor 7 is started, the bidirectional threaded rod 6 rotates, causing the two connecting plates 8 to move synchronously closer or further away along the sliding groove 5, adjusting the distance between the two clamping assemblies 10.

[0025] The tail of the second hydraulic rod 23 of the clamping assembly 10 is fixed to the end of the connecting plate 8 by bolts. The front and rear sides of the main body of the second hydraulic rod 23 are respectively welded with first fixing plates 24, and the front and rear sides of the telescopic part are respectively welded with second fixing plates 25. One end of the clamping rod 26 is hinged to the first fixing plate 24 by a pin, and the other end is fixed to the outer wall of the second arc-shaped clamping plate 11 by bolts. One end of the connecting rod 27 is hinged to the second fixing plate 25 by a pin, and the other end is hinged to the middle position of the clamping rod 26 by a pin. When it is necessary to clamp the round tube, the PLC controller controls the second hydraulic rod 23 to extend, pushing the second fixing plate 25 to move forward. The connecting rod 27 drives the clamping rod 26 to rotate around the hinge point of the first fixing plate 24, so that the two second arc-shaped clamping plates 11 move closer to the round tube and clamp it. When the round tube is released, the second hydraulic rod 23 retracts.

[0026] A placement groove 12 is formed on the opposite side of the second arc-shaped clamping plate 11. A rubber pad 13 is embedded in the placement groove 12, and the inner sidewall of the rubber pad 13 is in contact with the outer surface of the circular tube. A first slot is formed at the upper and lower ends of the placement groove 12. A telescopic spring 30 and a round-headed locking block 28 are installed in the first slot. One end of the telescopic spring 30 is welded to the sidewall of the first slot, and the other end is welded to the end of the round-headed locking block 28. A semi-circular groove 29 is formed at the upper and lower ends of the rubber pad 13. The round-headed locking block 28 is locked into the semi-circular groove 29 under the elastic force of the telescopic spring 30, thereby fixing the rubber pad 13. Second limiting blocks 31 are symmetrically welded to both sides of the round-headed locking block 28. A second limiting groove 32 is formed on the sidewall of the first slot. The second limiting blocks 31 are embedded in the second limiting groove 32 to prevent the round-headed locking block 28 from falling out.

[0027] The PLC controller is electrically connected to the first servo motor 2, the first hydraulic rod 20, the second servo motor 7, and the second hydraulic rod 23 via wires. It can preset parameters such as tilting angle and clamping force to realize the automated collaborative operation of each component.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
