Description

Technical Field

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

[0002] Stainless steel pipe polishing is a metal surface treatment process designed to improve the surface finish and aesthetics of stainless steel pipes, while enhancing their corrosion resistance and service life. This process includes three stages: rough polishing, fine polishing, and mirror polishing. Rough polishing primarily removes the oxide film and weld marks from the surface, fine polishing makes the surface smoother, and mirror polishing achieves a high gloss finish. Polishing not only improves the appearance of the stainless steel pipe but also enhances its corrosion resistance by forming a dense oxide film. Stainless steel pipe polishing is widely used in architectural decoration, home furniture, and catering equipment, such as for stair railings, balustrades, doors, and windows. Polished stainless steel pipes are characterized by high temperature resistance and corrosion resistance, making them suitable for various environments.

[0003] Currently, when polishing stainless steel pipes, it is often necessary to clamp one end with a clamp to ensure that the stainless steel pipe can be moved under the action of the clamp. However, in this way, the clamp will inevitably wrap around the outside of the end of the stainless steel pipe, which will result in the entire stainless steel pipe not being able to complete the grinding and polishing process.

[0004] Therefore, a stainless steel pipe polishing, grinding and fastening device is proposed to solve or alleviate the above problems. Utility Model Content

[0013] Preferably, the distance detection circuit includes

[0014] A distance sensor is mounted on a stand, and the illumination path of the distance sensor passes through the extension line of the central axis of the rotating shaft. The distance sensor detects the distance between itself and the stainless steel tube and feeds back a distance signal.

[0033] A stainless steel pipe polishing, grinding, and fastening device, such as Figure 1 and Figure 2 As shown, the system includes a worktable 1, a guide rail 2 fixedly connected to the worktable 1, a slide block 4 slidably connected to the guide rail 2, a stand 5 fixedly connected to the slide block 4, a rotating sleeve 8 rotatably mounted on one side of the stand 5, a fixed flange 9 fixedly connected to the outer ring of the rotating sleeve 8 away from the stand 5, and a rotating shaft 7 that passes through the stand 5 and the rotating sleeve 8 and is rotatably mounted. Protruding guide bars 3 are fixedly connected to both sides of the guide rail 2 along its length. Two symmetrically arranged semi-linear bearings 14 are fixedly connected to the top surface of one end of the guide rail 2. A guide rod 13 passing through the semi-linear bearings 14 is fixedly connected to the stand 5. The slide block 4 and the guide bars 3 are also slidably connected.

[0034] A movable flange 10 is fixedly connected to the end of the rotating shaft 7. An elastic ring 11 is fixedly connected to the side of the movable flange 10 facing the fixed flange 9. The distance between the movable flange 10 and the fixed flange 9 is adjustable. An electromagnet 6 is fixedly connected to the side of the upright frame 5 away from the rotating sleeve 8. The rotating shaft 7 passes through the electromagnet 6. There is a gap between the rotating sleeve 8 and the rotating shaft 7. A metal spring 12 is installed in the gap. One end of the metal spring 12 abuts against the upright frame 5, and the other end of the metal spring 12 is fixedly connected to the fixed flange 9. The elastic ring 11 is made of rubber.

[0035] like Figure 3 and Figure 4 As shown, it also includes a distance detection circuit, which is installed on the stand 5. The distance detection circuit detects the presence of a stainless steel pipe on the outside of the moving flange 10 and energizes the electromagnet 6.

[0036] Preferably, the distance detection and control circuit includes a distance sensor 15, a voltage comparison circuit 16, and a switching circuit 17. The voltage comparison circuit 16 includes a minimum circuit based on a voltage comparator LM358. The switching circuit 17 includes a transistor switch, with the base, collector, and emitter of the transistor switch being the controlled terminal, the energized terminal, and the ground terminal of the switching circuit 17, respectively. The relay 18 is a normally open relay 18.

[0037] Distance sensor 15 is mounted on stand 5, and the illumination path of distance sensor 15 passes through the extension line of the central axis of rotating shaft 7. Distance sensor 15 detects the distance between itself and the stainless steel tube and feeds back a distance signal. The input terminal of voltage comparison circuit 16 is coupled to the output terminal of distance sensor 15. The voltage comparator outputs a comparison signal after the voltage of the distance signal is less than the voltage of the preset distance reference signal. The output terminal of voltage comparison circuit 16 is coupled to the controlled terminal of switch circuit 17. The power-on terminal of switch circuit 17 is energized. The ground terminal of switch circuit 17 is connected in series with relay 18 and then connected to electromagnet 6. A push-button switch 19 is connected in series between relay 18 and electromagnet 6.

[0038] When this invention requires polishing and grinding the surface of a stainless steel pipe, the operator only needs to manually place the stainless steel pipe over the outside of the moving flange 10 and the fixed flange 9. At this time, the distance sensor 15 can detect the change in distance between itself and the stainless steel pipe, and then the distance sensor 15 can send a distance signal to the voltage comparison circuit 16. After the voltage comparator responds to the distance signal voltage being less than the preset distance reference signal voltage and outputs a comparison signal, the base of the switching circuit 17 can receive a high-level comparison signal, which in turn makes the collector and emitter of the switching circuit 17 conduct, thereby energizing the relay 18. After the relay 18 is energized, it can control the normally closed relay 18 connected in series with the electromagnet 6 to close, thereby energizing the electromagnet 6. After the electromagnet 6 is energized, it can generate magnetic force, which in turn causes the electromagnet 6 to exert force on the metal spring. When the metal spring 12 is engaged, it pulls the moving flange 10, causing a change in the distance between the moving flange 10 and the fixed flange 9. This allows the moving flange 10 and the fixed flange 9 to clamp the elastic ring 11 between them, causing the elastic ring 11 to undergo elastic deformation and expand outward. This allows the elastic ring 11 to abut against the inner ring of the stainless steel pipe, supporting one end of the stainless steel pipe. Then, the slide block 4 only needs to move along the length of the guide rail 2 to move the stainless steel pipe together. After the surface polishing of the stainless steel pipe is completed, simply press the button switch 19 to de-energize the electromagnet 6, causing the metal spring 12 to release its elastic potential energy. This causes the moving flange 10 and the fixed flange 9 to separate and no longer clamp the elastic ring 11. The elastic ring 11 can then detach from the inner wall of the stainless steel pipe, allowing the operator to remove the stainless steel pipe.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
