Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically a multi-diameter clamping mechanism for pipeline production. Background Technology

[0002] A clamping mechanism is a mechanical or mechatronic component used in machining, automated production, and equipment assembly to fix, position, or constrain workpieces or objects, keeping them in a stable posture or position so that subsequent operations (such as machining, inspection, handling, and assembly) can be carried out smoothly. Its core function is to apply controllable forces to counteract external forces (such as cutting forces, gravity, and inertial forces) on the workpiece during operation, preventing workpiece displacement or shaking, while ensuring operational accuracy and safety.

[0003] Pipe clamping mechanisms for pipeline production are specialized clamping devices designed specifically for the entire pipeline production process. Their core function is to achieve stable fixation, precise centering, and damage-proof clamping of pipes of different diameters by adapting to the circular or irregular shapes of the pipes. This ensures the accuracy and efficiency of subsequent processing or conveying procedures and is one of the core components of automated pipeline production lines.

[0004] Existing pipe clamping mechanisms for pipe production are relatively simple and do not allow for proper adjustment of the clamping device according to the pipe diameter, thus reducing the scope of application of the equipment. Furthermore, the clamping device is prone to displacement during the clamping process, which necessitates improving the accuracy of the clamping device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-diameter clamping mechanism for pipe production, so as to solve the technical problems mentioned in the background art.

One end of the contact block is provided with a groove, which makes the groove fit with the pipe, effectively improving the stability of the device. Secondly, the relative movement of the contact blocks driven by the drive motor also improves the working efficiency of the clamping device. Through the setting of limiting blocks and ball bearings, the inner wall of the base is provided with limiting blocks and ball bearings, which makes the ball bearings fit with the outer wall of the pipe.

[0012] The present invention is further configured such that the inner wall of the spring is provided with a telescopic rod, and the limiting block and the ball are both arc-shaped.

[0013] Preferably, the telescopic rod improves the stability of the spring during movement and reduces the phenomenon of spring deflection.

[0015] Preferably, the rotation of the drive motor causes the first rotating rod and the second rotating rod to rotate, thereby causing the movable rod to move the contact block closer to the pipe for clamping.

[0016] The present invention is further configured such that the output end of the drive motor is connected to the movable rod, and the connecting rod is movably connected to the first rotating rod and the second rotating rod.

[0017] Preferably, this improves the working efficiency of the clamping device and reduces energy consumption.

[0018] The present invention is further configured such that the pressing block and the contact block are fixedly installed on the outer wall of the movable rod, and the two sets of pressing blocks and contact blocks are arranged opposite to each other.

[0019] Preferably, the center of the cavity is between the two sets of contact blocks, and the contact blocks are arranged opposite to the center of the cavity to improve the accuracy of the device.

[0020] The present invention is further provided that one end of the contact block is provided with a groove, and the groove is in the shape of an arc or sawtooth.

[0021] Preferably, the groove contacts the pipe to improve the accuracy of the device.

[0022] The present invention is further configured such that the groove is made of silicone and fits against the outer wall of the pipe.

[0023] Preferably, the friction between the groove and the pipe is increased, which effectively improves the stability of the pipe after it is clamped.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model uses pressing blocks and contact blocks to clamp the pipe synchronously. One end of the contact block is provided with a groove, which fits the groove with the pipe, effectively improving the stability of the device. Furthermore, the relative movement of the contact blocks by the drive motor also improves the working efficiency of the clamping device.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] First embodiment:

[0037] Please see Figures 1-5 The system includes a base 1, a drive motor 2 on the top of the base 1, a first rotating rod 3 at one end of the drive motor 2, a connecting rod 4 on the outer wall of the first rotating rod 3, and a second rotating rod 5 connected to the other end of the connecting rod 4. Both the first rotating rod 3 and the second rotating rod 5 have contact blocks 7 on their outer walls, and a pressing block 6 on the top of the contact block 7. A limit block 10 is provided on the inner wall of the base 1, and a ball bearing 12 is movably mounted on one end of the limit block 10. Through the arrangement of the pressing block 6 and the contact block 7, the two sets of pressing blocks 6 and contact blocks 7... The pipe is clamped synchronously, and a groove 8 is provided at one end of the contact block 7, which makes the groove 8 fit with the pipe, effectively improving the stability of the device. Secondly, the contact block 7 is moved relative to the drive motor 2, which also improves the working efficiency of the clamping device. With the setting of the limit block 10 and the ball 12, the inner wall of the base 1 is provided with the limit block 10 and the ball 12, which makes the ball 12 fit with the outer wall of the pipe, and the limit block 10 pushes the ball 12 to make close contact with the pipe, effectively improving the accuracy and stability of the clamping device.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The base 1 has a cavity 11 on its central axis, and a spring 9 is provided on the inner wall of the cavity 11. The spring 9 limits the position of the limiting block 10, which effectively improves the stability of the limiting block 10 during movement.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 A limit block 10 is provided at one end of the spring 9 near the pipe, and the ball 12 is in contact with the pipe. Under the action of the spring 9, the ball 12 is made to fit with the pipe according to the change of the pipe diameter, which effectively improves the practicality of the device.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The inner wall of the spring 9 is provided with a telescopic rod, and the limiting block 10 and the ball 12 are both arc-shaped. The telescopic rod improves the stability of the spring 9 during movement and reduces the phenomenon of spring 9 deviating.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 Both ends of the base 1 are provided with movable rods, and the outer wall of the movable rods is equipped with a first rotating rod 3 and a second rotating rod 5. The movable rods are fixedly connected to the first rotating rod 3 and the second rotating rod 5, so that the rotation of the drive motor 2 drives the first rotating rod 3 and the second rotating rod 5 to rotate, thereby causing the movable rods to drive the contact block 7 to move closer to the pipe for clamping.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The output end of the drive motor 2 is connected to the movable rod, and the connecting rod 4 is movably connected to the first rotating rod 3 and the second rotating rod 5, which improves the working efficiency of the clamping device and reduces energy consumption.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The pressing block 6 and the contact block 7 are fixedly installed on the outer wall of the movable rod, and the two sets of pressing blocks 6 and contact blocks 7 are arranged opposite each other. The middle of the two sets of contact blocks 7 is the central axis point of the cavity 11, and the contact blocks 7 are arranged opposite to the central axis point of the cavity 11, which improves the accuracy of the device.

[0044] Second embodiment:

[0045] Please see Figures 1-4 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a groove 8 is provided at one end of the contact block 7, and the groove 8 contacts the outer wall of the pipe. Furthermore, the material around the groove 8 is silicone, which increases the friction between the groove 8 and the pipe, effectively improving the stability of the pipe after it is clamped.

[0046] In practical operation, this utility model is as follows:

[0047] When the device needs to clamp the pipe, the pipe is first placed on the inner wall of the limiting block 10, so that under the action of the spring 9, the ball 12 fits against the outer wall of the pipe, temporarily limiting the pipe. Then, the drive motor 2 is driven, which drives the first rotating rod 3 to rotate. The rotation of the first rotating rod 3 drives the connecting rod 4 and the second rotating rod 5 to rotate, so that the two sets of contact blocks 7 move relative to each other, clamping the pipe on the central shaft, effectively improving the working efficiency of the clamping device.

[0048] Furthermore, the outer wall of the contact block 7 is provided with a groove 8, which contacts the pipe. The groove 8 is arc-shaped and made of silicone, which increases the friction between the groove 8 and the pipe, making the device suitable for clamping pipes of different diameters within a certain range and improving the practicality of the device.
