A reducer polishing device

Abstract

This utility model discloses a grinding device for reducing pipes, including a base, a support plate fixedly installed on the top of the base, a rotating assembly inside the support plate, a rotating tube inside the support plate via the rotating assembly, a rotating component on the top of the support plate and connected to the rotating tube, an adjusting component inside the rotating tube, and a mounting frame inside the rotating tube via the adjusting component, with a grinding belt fixedly installed inside the mounting frame. Since the grinding belt is made of a soft material, it allows for better contact with the reducing pipe. Simultaneously, the rotating assembly allows the rotating tube to rotate along with it, causing the adjusting component, mounting frame, and grinding belt to rotate together with the rotating tube. This allows the grinding belt to complete the grinding of the reducing pipe's outer surface in one pass without any missed areas, thus completing the grinding of the reducing pipe's outer surface more quickly.

Description

Technical Field

[0001] This utility model relates to the field of reducing pipe grinding technology, and in particular to a reducing pipe grinding device. Background Technology

[0002] A reducer (also known as a reducing fitting or reducing connector) is a chemical pipe fitting used to connect two pipes of different diameters. It comes in concentric and eccentric types and is widely used in industries such as petroleum, chemical, and power. Reducers are key connecting components in piping systems; their core function is to achieve seamless connection between pipes of different diameters through a diameter-changing design, ensuring smooth fluid transport and system flexibility.

[0003] In the process of processing reducers, it is often necessary to grind the outer surface of the reducer. Since the diameter of the reducer changes continuously along the axial direction, it is difficult for traditional rigid grinding wheels or grinding heads with fixed curvature to maintain surface contact with the conical surface at all times, which can easily lead to missed grinding. Although the manual hand-held sanding belt method can partially adapt to the change in pipe diameter, it is labor-intensive and inefficient. Therefore, this utility model provides a reducer grinding device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grinding device for reducing pipe diameter, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grinding device for reducing pipes includes a base, a support plate fixedly mounted on the top of the base, a rotating assembly inside the support plate, a rotating pipe inside the support plate via the rotating assembly, a rotating component on the top of the support plate and connected to the rotating pipe, an adjusting component inside the rotating pipe, a mounting frame inside the rotating pipe via the adjusting component, and a grinding belt fixedly mounted inside the mounting frame.

[0006] Preferably, the rotating assembly includes a rotating rail disposed inside the support plate, a rotating plate slidably connected inside the rotating rail, and the rotating plate being fixedly connected to the rotating tube.

[0007] Preferably, the rotating assembly includes a dual-axis motor disposed on the top of the support plate, a first gear is fixedly mounted on the output end of the dual-axis motor, a second gear is meshed on the surface of the first gear, and the second gear is fixedly connected to the rotating tube.

[0008] Preferably, the adjustment assembly includes a frame disposed inside the rotating tube, a drive motor is fixedly installed inside the frame, a screw is fixedly installed at the output end of the drive motor, the screw is rotatably connected to the frame, a movable plate is threadedly connected to the surface of the screw, the movable plate is slidably connected to the frame, and the movable plate is fixedly connected to the mounting bracket.

[0009] Preferably, there are multiple polishing belts, and the multiple polishing belts are distributed alternately in pairs.

[0010] Preferably, the rotating plate has a convex cross-section, and the rotating rail is adapted to the rotating plate.

[0011] Preferably, there are two second gears, and the two second gears are symmetrically distributed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the process of the reducer passing through the rotating tube, the mounting bracket can be moved towards the reducer by the adjustment component, so that the grinding belt can move towards the reducer and make contact with the reducer. Since the grinding belt is made of soft material, it can make better contact with the reducer. At the same time, the rotating component can make the rotating tube rotate along the rotating component, so that the adjustment component, mounting bracket and grinding belt can rotate together with the rotation of the rotating tube. This allows the grinding belt to complete the grinding of the outer surface of the reducer in one go without any missed grinding, and the grinding of the outer surface of the reducer can be completed more quickly.

[0015] 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 protection scope of the present utility model.

[0016] Example: Refer to Figure 1-4 A grinding device for reducing pipes includes a base 1, a support plate 2 fixedly mounted on the top of the base 1, a rotating assembly inside the support plate 2, a rotating pipe 5 connected to the rotating assembly inside the support plate 2, a rotating component connected to the rotating pipe 5 at the top of the support plate 2, an adjusting assembly inside the rotating pipe 5, and a mounting frame 13 connected to the adjusting assembly inside the rotating pipe 5. A grinding belt 14 is fixedly mounted inside the mounting frame 13. The adjusting assembly includes a frame 9 inside the rotating pipe 5, a drive motor 10 fixedly mounted inside the frame 9, a screw 11 fixedly mounted at the output end of the drive motor 10, the screw 11 being rotatably connected to the frame 9, a movable plate 12 threadedly connected to the surface of the screw 11, the movable plate 12 being slidably connected to the frame 9, and the movable plate 12 being fixedly connected to the mounting frame 13. The adjusting assembly facilitates the adjustment of the position of the mounting frame 13, thereby facilitating the adjustment of the position of the grinding belt 14. In the middle position, the reducer can be better positioned in the middle of the rotating tube 5, and the grinding belt 14 can better contact the rotating tube 5 subsequently. There are multiple grinding belts 14, and the multiple grinding belts 14 are distributed in pairs. In this reducer grinding device, during the process of the reducer passing through the rotating tube 5, the mounting bracket 13 can be moved towards the reducer by the adjustment component, so that the grinding belt 14 can be moved towards the reducer and make contact with the reducer. Since the grinding belt 14 is made of soft material, it can make better contact with the reducer. At the same time, the rotating tube 5 can be rotated along the rotating component by the rotating component, so that the adjustment component, mounting bracket 13, and grinding belt 14 can rotate together with the rotation of the rotating tube 5, so that the grinding belt 14 can complete the grinding of the outer surface of the reducer in one go without any missed grinding, and the grinding of the outer surface of the reducer can be completed more quickly.

[0017] Specifically, the rotating assembly includes a rotating rail 3 disposed inside the support plate 2, a rotating plate 4 slidably connected inside the rotating rail 3, the rotating plate 4 having a convex cross-section, the rotating rail 3 and the rotating plate 4 being adapted to each other, and the rotating plate 4 being fixedly connected to the rotating tube 5. The rotating assembly enables the rotating tube 5 to rotate. The rotating assembly also includes a dual-axis motor 6 disposed on the top of the support plate 2, a first gear 7 fixedly mounted on the output end of the dual-axis motor 6, and a second gear 8 meshing on the surface of the first gear 7. There are two second gears 8, which are symmetrically distributed. The second gears 8 are fixedly connected to the rotating tube 5. The rotating assembly facilitates the provision of driving force for the rotation of the rotating tube 5. By using the rotating assembly in conjunction with the rotating tube 5, the rotating tube 5 can rotate stably.

[0018] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0019] In use: As the reducer passes through the rotating tube 5, the drive motor 10 causes the screw 11 to rotate, which in turn causes the moving plate 12 to move along the frame 9 toward the reducer, the mounting bracket 13 to move toward the reducer, and the grinding belt 14 to move toward the reducer, so that the grinding belt 14 comes into contact with the reducer. Since the grinding belt 14 is made of soft material, it can make better contact with the reducer. At the same time, the dual-axis motor 6 causes the first gear 7 to rotate, which in turn causes the second gear 8 to rotate, which causes the rotating tube 5 and the rotating plate 4 to rotate along the rotating rail 3. The frame 9, drive motor 10, screw 11, moving plate 12, mounting bracket 13, and grinding belt 14 all rotate together with the rotating tube 5, so that the grinding belt 14 can complete the grinding of the outer surface of the reducer in one go.
