Description

Technical Field

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

[0002] Physical polishing of pipes is a mechanical process that removes minor imperfections and irregularities from the pipe surface, aiming to improve its surface smoothness and precision. This process typically uses a polishing machine, polishing discs, and appropriate polishing compounds. Through high-speed rotation and mechanical force, the pipe surface gradually becomes smooth and flat without a chemical reaction. Physical polishing is widely used in the surface treatment of metal pipes such as stainless steel, aluminum alloy, and copper. It effectively removes oxide layers, processing marks, and other surface defects, achieving a mirror finish. This process not only improves the aesthetics of the pipes but also enhances their corrosion resistance and stain resistance. Compared to chemical polishing, physical polishing is more environmentally friendly and energy-efficient, and can achieve more refined surface treatments, making it widely used in industries such as decoration, precision instruments, and medical devices. Through physical polishing of pipes, the service life and performance of products are significantly improved, meeting high-quality requirements.

[0003] Currently, when polishing the surface of pipes, the pipe diameter varies from batch to batch. As a result, operators need to adjust the equipment according to the pipe diameter between processing sessions. If the pipe diameter varies significantly, it may even be necessary to replace the equipment for polishing. This undoubtedly increases the cost of pipe processing and polishing for manufacturers.

[0004] Therefore, a round tube grinding and polishing device is proposed to solve or alleviate the above problems. Utility Model Content

[0027] A round tube grinding and polishing equipment, such as Figures 1 to 3 As shown, it includes a worktable 1, a slide 2 fixedly connected to the top surface of the worktable 1, an upper slide 7 that can move back and forth along the length of the slide 2, and a mounting bracket 4 fixedly connected to the worktable 1 and located on both sides of the slide 2. A soft grinding component is provided on the side of the mounting bracket 4 facing the slide 2, and the upper slide 7 can guide the round tube to move back and forth in the soft grinding component.

[0028] Several guide rails 3 are fixedly connected to the slide 2, and a lower slide seat 6 is slidably connected to the guide rails 3. Several lower slide seats 6 are fixedly connected to the bottom surface of the upper slide seat 7. A fixed seat 8 located at one end of the slide 2 is fixedly connected to the worktable 1. A cylinder 9 is fixedly connected to the end of the fixed seat 8 away from the slide 2. The piston rod of the cylinder 9 passes through the fixed seat 8 and is fixedly connected to the upper slide seat 7.

[0029] A servo motor 11 is fixedly connected to the top surface of the upper slide block 7. A three-jaw chuck 12 is fixedly connected to the output shaft of the servo motor 11. Several jaws 13 are present in the three-jaw chuck 12. An elastic abutment 14 is fixedly connected to the outer ring of the jaws 13. The elastic abutment 14 is made of rubber.

[0030] The soft polishing assembly includes a sheet-shaped friction belt 5 and connecting ropes fixedly connected to both ends of the friction belt 5. The connecting ropes pass through the mounting frame 4 and can be tied at both ends of the friction belt 5 to adjust the tightness between the friction belt 5 and the round tube.

[0031] When an operator needs to use this grinding and polishing equipment to grind and polish the surface of a round tube, the round tube is passed through the friction band 5 in the flexible grinding component. Then, the end of the round tube passing through the flexible grinding component is fixed by a three-jaw chuck 12. When fixing the round tube, several jaws 13 in the three-jaw chuck 12 can expand outwards, causing the elastic contact member 14 to abut against the inner ring of the round tube, thereby fixing and supporting one end of the round tube. Then, the connecting ropes at both ends of the friction band 5 are tightened manually, so that the friction band 5 in the flexible grinding component on both mounting brackets 4 can tightly wrap around the outer ring of the round tube, and also move the round tube away from the three jaws. One end of the chuck 12 provides good support. Then, the servo motor 11 and the cylinder 9 are started, so that the cylinder 9 can push the upper slide 2 to move back and forth along the length of the slide 2. During the displacement, the upper slide 7 can move back and forth stably relative to the guide rail 3 through the lower slide 6. At the same time, the servo motor 11 can drive the three-jaw chuck 12 to rotate, which in turn drives the round tube to rotate together, so that the round tube can be polished with the friction band 5 in the soft grinding component at any position in its length direction. If the inner diameter of the round tube is different, then the three-jaw chuck 12 only needs to be moved outward to adapt to the diameter of the round tube, so that the equipment can have a wider range of applications and reduce the cost of equipment preparation for manufacturers.

[0032] 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.
