Description

Technical Field

[0001] The present application relates to the technical field of pipe grinding, and more specifically, to a double-headed grinding device for pipes. Background Art

[0002] The double-head grinding device for pipe fittings is a device used to grind both ends of pipe fittings. It can grind both ends of the pipe fittings at the same time. Through the corresponding grinding head and mechanical structure, it effectively improves the efficiency and quality of pipe fitting grinding.

[0003] Traditional pipe grinding devices usually use simple mechanical clamps or manual clamping methods. It is difficult to achieve accurate, stable and non-destructive fixation for pipes of different thicknesses. If the clamp is clamped too tightly, it is easy to leave clamp marks and scratches on the surface of the pipe, seriously affecting the appearance quality of the pipe. If the clamp is not clamped tightly enough, the pipe is very likely to shake and shift under the action of the high-speed rotating grinding wheel. At the same time, the existing device cannot grind both ends of the pipe at the same time, resulting in extremely low grinding efficiency. It can only process both ends of the pipe in turn, which consumes a lot of time and labor costs, and seriously restricts production progress and capacity improvement. Secondly, it is difficult to ensure the consistency of the grinding quality at both ends.

[0004] In view of this, the present application proposes a double-end grinding device for pipe fittings. Utility Model Content

[0013] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0014] 1. This application moves the movable plate and the connecting plate so that the pressing soft plate cooperates with the silicone sheet on the placement table to clamp the pipe. The electric telescopic rod provides stable and adjustable pressure to ensure that the pipe is firmly fixed during the polishing process. The silicone sheet not only has good anti-slip properties, but also can buffer the pressure between the pipe and the placement table to prevent the surface of the pipe from being scratched, further enhancing the reliability of pipe fixation, reducing polishing defects caused by shaking of the pipe, and improving the stability and yield of the polishing process. At the same time, the distance between the pressing soft plate and the placement table is adjusted by moving the pressing soft plate, so that the device can adapt to pipes of different thicknesses.

[0015] 2. This application uses the meshing transmission of gears and staggered racks to precisely control the movement of the two racks, thereby driving the fixed frames at both ends to approach each other and clamp the pipe. Under the continuous drive of the servo motor, it can ensure that the grinding disc is always in close contact with both ends of the pipe during the grinding process, ensuring the uniformity and consistency of the grinding. At the same time, it can adapt to the fixing requirements of pipes of different lengths. The dual-head synchronous grinding method greatly improves the grinding efficiency. Compared with the traditional single-head sequential grinding, it greatly shortens the time cost of pipe grinding and improves the overall efficiency of production and processing.

[0020] The present application is further described in detail below with reference to the accompanying drawings.

[0021] Reference Figure 1-Figure 3 , an embodiment of the present application provides a double-end grinding device for pipe fittings, including a workbench 1 and a pair of grinding mechanisms for grinding both ends of the pipe fittings, a fixed plate 2 is fixedly connected to the rear of the upper end surface of the workbench 1, a pair of racks 3 are staggered inside the fixed plate 2, and the two grinding mechanisms are located at one end of the two racks 3 away from each other; a driving component is provided inside the workbench 1 for driving the two racks 3 to move staggered, the upper end surface of the workbench 1 is provided with a fixing mechanism, and the fixing mechanism can fix pipe fittings of different thicknesses; the fixing mechanism includes a placing table 8 fixedly connected to the upper end surface of the workbench 1, and a movable pressing soft plate 10 located above the placing table 8, the distance between the pressing soft plate 10 and the placing table 8 is adjusted by moving the pressing soft plate 10, so that the device can adapt to pipe fittings of different thicknesses.

[0022] The two ends of the pressing soft board 10 are fixedly connected with connecting plates 11, and the connecting plates 11 pass through the workbench 1. The lower end surface of the connecting plate 11 is fixedly connected with a movable plate 12. The front of the upper end surface of the workbench 1 is fixedly connected with an electric telescopic rod 13, and the telescopic end of the electric telescopic rod 13 passes through the workbench 1 and is fixedly connected to the movable plate 12. The electric telescopic rod 13 provides stable and adjustable pressure to ensure that the pipe is firmly fixed during the grinding process.

[0023] The upper end surface of the placement table 8 is fixedly connected with a silicone sheet 9. The silicone sheet 9 not only has good anti-slip performance, but also can buffer the pressure between the pipe and the placement table 8, preventing the surface of the pipe from being scratched, further enhancing the reliability of the pipe fixation, reducing the polishing defects caused by the shaking of the pipe, and improving the stability and yield of the polishing process.

[0024] The driving assembly includes a connecting groove 14 opened inside the fixed plate 2, and extension grooves 15 are opened above and below the inside of the connecting groove 14, and the extension groove 15 passes through the fixed plate 2. The inside of the connecting groove 14 is rotatably connected to a gear 16, and the rack 3 is slidably connected to the inside of the extension groove 15, and the gear 16 and the rack 3 are meshed with each other. The rear end face of the fixed plate 2 is fixedly connected to a servo motor 7, and the output end of the servo motor 7 is fixedly connected to the gear 16. With the help of the meshing transmission of the gear 16 and the staggered racks 3, the movement of the two racks 3 is precisely controlled, thereby driving the grinding mechanisms at both ends to approach each other and achieve clamping of the pipe fittings, thereby achieving a good positioning effect.

[0025] The grinding mechanism includes a fixed frame 4 fixedly connected to one end of the gear 16, and the internal rotation of the fixed frame 4 is connected to the grinding disc 5. One end of the fixed frame 4 is fixedly connected to the fixed motor 6, and the output end of the fixed motor 6 is fixedly connected to the grinding disc 5. Under the continuous drive of the servo motor 7, the grinding disc 5 can be ensured to always be close to both ends of the pipe during the grinding process, ensuring the uniformity and consistency of the grinding, and at the same time being able to adapt to the fixing requirements of pipes of different lengths. The double-head synchronous grinding method greatly improves the grinding efficiency. Compared with the traditional single-head sequential grinding, the time cost of pipe grinding is greatly shortened, and the overall efficiency of production and processing is improved.

[0026] Working Principle: When in use, the staff will place the pipe fitting on the silicone sheet 9 of the placement table 8. First, start the servo motor 7. The output end of the servo motor 7 rotates, driving the gear 16 in the connecting slot 14 to rotate. Since the gear 16 is meshed with the racks 3 inside the two staggered extension slots 15, the rotation of the gear 16 drives the two racks 3 to move. The movement of the two racks 3 drives the fixed frames 4 at both ends closer to each other until the grinding discs 5 inside the two fixed frames 4 clamp the pipe fitting. Start the electric telescopic rod 13. The telescopic end of the electric telescopic rod 13 extends and drives the movable plate 12 to move downward. The movement of the movable plate 12 drives the two connecting plates 11 to move downward. The downward movement of the two connecting plates 11 drives the pressing soft plate 10 to move toward the pipe fitting until the pressing soft plate 10 and the placement table 8 clamp the pipe fitting. The silicone sheet 9 plays a good anti-slip role, preventing the pipe fitting from shifting during the grinding process.

[0027] After the pipe is secured, the fixed motors 6 on the two fixed frames 4 are activated. The output terminals of the fixed motors 6 drive the grinding discs 5 to rotate, grinding both ends of the pipe. Driven by the servo motor 7, the grinding discs 5 always remain in close contact. When the pipe is polished, the fixed motors 6 are turned off, the grinding discs 5 stop rotating, and the output terminals of the servo motor 7 rotate in the opposite direction. The two fixed frames 4 move away from each other, and the telescopic end of the electric telescopic rod 13 contracts, pressing the flexible plate 10 to lift and detach it from the pipe. Finally, the worker can remove the pipe.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
