Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipe processing technology, specifically a device for grinding the outer circle of pipe fittings. Background Technology
[0002] Grinding can remove oxide layers, burrs, and rough parts from the surface of pipe fittings, significantly improving the surface finish. Pipe fitting outer circle grinding equipment can precisely adjust the outer circle size and shape of the pipe fitting to meet the design specifications. Especially in mass production, manual grinding is difficult to guarantee consistency and accuracy, while automated grinding equipment can ensure that the dimensional error of the pipe fitting is controlled within a minimum range.
[0003] The principle of the pipe fitting outer diameter grinding device mainly involves two aspects: the principle of rotational motion and the principle of friction. By precisely applying the principles of rotational motion and friction, the pipe fitting outer diameter grinding device can efficiently grind the outer diameter of the pipe fitting, providing strong support for the outer diameter grinding of pipe fittings.
[0004] Existing grinding devices often place the pipe between multiple rotating rollers and grind it using the grinding rollers. However, due to the lack of a fixing mechanism, the pipe may move or slide during the grinding process, resulting in uneven grinding and affecting the surface quality. Therefore, a pipe outer diameter grinding device is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technology, existing grinding devices often place the pipe between multiple rotating rollers and grind it using the grinding rollers. However, due to the lack of a fixing mechanism, the pipe may move or slide during the grinding process, resulting in uneven grinding and affecting the surface quality. This utility model proposes a grinding device for the outer circle of pipes.
[0006] The technical solution adopted by this utility model to solve its technical problem is a device for grinding the outer diameter of pipe fittings, including a working platform. Two second drive motors are fixedly installed at both ends of the top of the working platform. Drive components are installed at the output ends of multiple second drive motors. A baffle is fixedly and rotatably installed on the outer side of the drive components away from the second drive motors. The bottom of the baffle is fixedly installed on the top of the working platform. A fixed plate and a movable plate are fixedly installed on the top of the multiple drive components respectively. A rotating shaft is fixedly installed on one side of the fixed plate. A support plate is fixedly installed on the top of the working platform. A first drive motor is fixedly installed at the top. A rotating disk is installed on the rotating shaft of the first drive motor and the rotating shaft. A connecting disk is fixedly installed on the outer side of the rotating disk. A third drive motor is fixedly installed on the top of the moving plate. A grinding roller is installed at the output end of the third drive motor. A threaded rod is driven to rotate by a second drive motor. The rotation of the threaded rod drives one of the connecting disks to move back and forth. When the pipe to be ground is placed between multiple connecting disks, its two ends are fixed. By fixing the two ends of the pipe to be ground, a more stable and uniform grinding effect can be achieved on its outer surface during the grinding process.
[0007] Preferably, the drive assembly includes multiple threaded rods, one end of each threaded rod is externally mounted on the output end of multiple second drive motors, and the other end of each threaded rod is rotatably mounted on the side of a baffle. Each threaded rod has a movable block on its exterior, and each movable block has a nut fixedly installed inside. The internal thread of the nut is installed on the exterior of the threaded rod. By connecting the threaded rods in the drive assembly with the internal threads of the movable blocks, the effect of fixing and grinding the pipe to be ground is achieved.
[0008] Preferably, the top of the working platform is provided with limit grooves at both ends, and limit blocks are slidably installed inside the limit grooves. The tops of the multiple limit blocks are respectively fixedly installed at the bottom ends of the multiple moving blocks. When the moving blocks are moving, the T-shaped limit grooves and T-shaped limit blocks can achieve the effect of fixing the multiple moving blocks as they move, thus preventing the moving blocks from moving when the threaded rod and nut rotate.
[0009] Preferably, a cylinder is fixedly installed on the top of one of the movable blocks, and the output end of the cylinder is installed on the outer side of the movable plate. The cylinder drives the movable block to move back and forth, thereby controlling the grinding roller to grind the pipe to be ground.
[0010] Preferably, a limiting plate is fixedly installed at both ends of the top of one of the movable blocks, and a connecting block is slidably installed inside the multiple limiting plates. The sides of the multiple connecting blocks are respectively fixedly installed on both sides of the movable plate. When the movable plate moves, the connection between the limiting plate and the connecting block can make the movable plate more stable when moving, so as to achieve a more precise and stable grinding effect during the grinding process.
[0011] Preferably, each of the connecting discs is provided with an anti-slip pad, which is made of rubber. The rubber material of the anti-slip pad increases the external friction of the pipe to be ground, preventing rotation during fixing.
[0012] The advantages of this utility model are:
[0013] This invention addresses the problem of uneven grinding and surface quality issues in existing grinding devices. These devices typically involve placing the pipe between multiple rotating rollers for grinding, which results in the pipe shifting or sliding during grinding due to the lack of a fixing mechanism.

[0022] 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 scope of protection of the present utility model.
[0023] Please see Figure 1-6As shown, a pipe fitting outer diameter grinding device includes a working platform 1. Second drive motors 4 are fixedly installed at both ends of the top of the working platform 1. Drive components are installed at the output ends of multiple second drive motors 4. A baffle 8 is fixedly and rotatably installed on the outer side of each drive component away from the second drive motors 4. The bottom of the baffle 8 is fixedly installed on the top of the working platform 1. A fixed plate 9 and a movable plate 17 are fixedly installed on the top of the multiple drive components, respectively. A rotating shaft 10 is fixedly installed on the outer side of the fixed plate 9. A support plate 2 is fixedly installed on the top of the working platform 1. A first drive motor 3 is fixedly installed on the top of the support plate 2. A rotating disk 11 is installed on the rotating shaft of both the first drive motor 3 and the rotating shaft 10. A connecting disk 12 is fixedly installed on the outer side of the rotating disk 11. A third drive motor 18 is fixedly installed on the top of the movable plate 17. A grinding roller 19 is installed at the output end of the third drive motor 18. During operation, existing pipe fitting grinding devices... When grinding the exterior of pipe fittings, the lack of a design to fix the exterior of the fittings can lead to uneven grinding. To address this issue, the device uses a second drive motor 4 to rotate a threaded rod 5. This rotation of the threaded rod 5 moves a moving block 6, which in turn moves a top fixed plate 9 and another connecting disc 12. When the exteriors of both connecting discs 12 are positioned at both ends of the pipe fitting to be ground, another second drive motor 4 is activated to rotate the threaded rod 5 connected to its output end. This rotation of the threaded rod 5 moves another moving block 6, which is threaded to its exterior. This movement of the moving block 6 moves the grinding roller 19. When the grinding roller 19 reaches the exterior of the pipe fitting, a cylinder 16 is activated to bring the grinding roller 19 into contact with the outer surface of the pipe fitting. Then, a third drive motor 18 is activated to rotate the grinding roller 19, achieving the desired grinding effect on the exterior of the pipe fitting.
[0024] The drive assembly includes multiple threaded rods 5. One end of each threaded rod 5 is externally mounted on the output end of multiple second drive motors 4. The other end of each threaded rod 5 is rotatably mounted on the side of a baffle 8. Each threaded rod 5 has a movable block 6 on its exterior. Each movable block 6 has a nut 7 fixedly installed inside its interior. The internal threads of the nut 7 are installed on the exterior of the threaded rod 5. During operation, existing pipe grinding devices, due to the lack of a design to fix the exterior of the pipe, cause uneven grinding of the pipe. In order to make the grinding of the pipe more uniform, this device drives the movable block 6 with the nut 7 inside to move by rotating the threaded rod 5. The movement of the movable block 6 drives one of the connecting discs 12 and the grinding roller 19 to move.
[0025] The working platform 1 has limit grooves 14 at both ends of its top. Limit blocks 15 are slidably installed inside the limit grooves 14. The tops of the multiple limit blocks 15 are respectively fixedly installed at the bottom ends of the multiple moving blocks 6. During operation, the existing pipe grinding device has the problem of uneven grinding of the pipe due to the lack of a design to fix the outside of the pipe. In order to make the grinding of the pipe more uniform, the device installs the limit blocks 15 inside the limit grooves 14, which makes the moving blocks 6 move more stably.
[0026] A cylinder 16 is fixedly installed on the top of one of the moving blocks 6, and the output end of the cylinder 16 is installed on the outer side of the moving plate 17. During operation, the existing pipe grinding device has the problem of uneven grinding when grinding the outside of the pipe due to the lack of a design to fix the outside of the pipe. In order to make the grinding of the pipe more uniform, the device can start and stop grinding by moving the grinding roller 19 back and forth through the cylinder 16.
[0027] One of the movable blocks 6 has a limit plate 20 fixedly installed at both ends of its top. Connecting blocks 21 are slidably installed inside the multiple limit plates 20. The sides of the multiple connecting blocks 21 are fixedly installed on both sides of the movable plate 17. During operation, the existing pipe grinding device has the problem of uneven grinding of the pipe due to the lack of a design to fix the outside of the pipe. In order to make the grinding of the pipe more uniform, the device limits the movement trajectory of the movable plate 17 by sliding the connecting blocks 21 inside the limit plates 20.
[0028] Each of the connecting discs 12 is provided with an anti-slip pad 13, which is made of rubber. During operation, existing pipe grinding devices, due to the lack of a design to fix the outside of the pipe, will cause uneven grinding of the pipe during the grinding process. In order to make the grinding of the pipe more uniform, the anti-slip pad 13 provided on the outside of the connecting disc 12 can increase the friction between the pipe and the inner wall of the pipe.
[0029] Working principle: During the production of pipe fittings, a grinding device is used to grind the exterior of the fittings. One end of the fitting to be ground is placed outside one of the connecting discs 12. Then, one of the second drive motors 4 is activated, driving the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives one of the moving blocks 6 to move. The movement of the moving block 6 drives the top fixing plate 9 and the other connecting disc 12 to move. The free movement of one of the connecting discs 12 allows for adjustment of the spacing and fixation of the fittings according to their different lengths. When the exteriors of both connecting discs 12 are positioned at both ends of the fitting and are in close contact with it, the grinding process can be completed. The two ends of the grinding pipe are fixed. Another second drive motor 4 is started to drive the threaded rod 5 connected to its output end to rotate. The rotation of the threaded rod 5 drives another moving block 6, which is threaded to the outside, to move. The movement of the moving block 6 drives the grinding roller 19 to move. When the grinding roller 19 moves to the outside of the pipe to be ground, the cylinder 16 is started to drive the grinding roller 19 to fit against the outer surface of the pipe to be ground. Then, the third drive motor 18 is started to drive the grinding roller 19 to rotate. The rotation of the grinding roller 19 achieves the effect of grinding the outside of the pipe to be ground. After the grinding is completed, the cylinder 16 is started to drive the grinding roller 19 to move backward, and finally the grinding is completed.
