[0002] In the process of pipe fitting processing, in order to maintain the smoothness of the outer circle of the pipe body, a polishing device is used to polish the outer circle of the pipe body. In the existing technology, the pipe fitting polishing process mainly includes mechanical polishing, chemical polishing, electrolytic polishing and wet polishing. Among them, mechanical polishing is to grind and polish the pipe body through physical operations such as grinding wheels and grinding paste. It is suitable for high-precision surfaces and can achieve extremely low roughness.

[0003] In existing technologies, when using mechanical polishing, the tube is placed between two grinding wheels, and the outer circle of the tube is polished by the rotation of the grinding wheels. However, during the polishing process, the position of the tube between the two grinding wheels needs to be manually controlled, which is inconvenient and cannot automatically polish the entire tube. At the same time, when polishing the tube with grinding wheels, a large amount of dust will be adsorbed on the outer circle of the tube. After polishing, the outer circle of the tube needs to be wiped manually with a sponge or wiping cloth, making the polishing process quite cumbersome. Utility Model Content

The device is equipped with a blowing device. The tube body passes through four V-shaped rods 4 and is wrapped around the tube body by the V-shaped rods 4. The outer circle of the tube body contacts the wiping cloth 8. During the polishing process of the outer circle of the tube body, the push rod 5 is moved by controlling the push rod 5 to push one end of the tube body, thereby moving the tube body during the polishing process, which facilitates the polishing process of the tube body. During the polishing process of the outer circle of the tube body, the tube body will rotate. At the same time, the moving outer circle of the tube body will contact the wiping cloth 8 at the top of the fixed plate 6, which can clean the dust on the outer circle of the tube body and improve the convenience of polishing the outer circle of the tube body.

[0022] like Figures 1 to 4 As shown, the purging device includes a fixed cylinder 9, a cavity 10, an air inlet pipe 11, and air holes 12. The fixed cylinder 9 is fixedly installed on one side of the base 1. The cavity 10 is opened in the middle of the fixed cylinder 9. The air inlet pipe 11 is fixedly installed at the bottom end of the fixed cylinder 9. The air inlet pipe 11 is connected to the interior of the cavity 10.

The air inlet pipe 11 is connected to the interior of the cavity 10. The pipe body passes through the middle of the fixed cylinder 9.

[0023] During the polishing process of the outer circle of the tube, the tube will pass through the middle of the fixed cylinder 9. Air will be introduced into the interior of the fixed cylinder 9 by a blower. The gas will be discharged through the cavity 10 and the air hole 12, which can further clean the dust on the outer circle of the tube.

[0024] like Figures 1 to 4 As shown, a mounting bracket 13 is fixedly mounted on the top of the mounting base 2, a grinding motor 14 is fixedly mounted on the top of the mounting bracket 13, a grinding wheel 15 is fixedly mounted on the output end of the grinding motor 14, and the tube body is positioned between the two grinding wheels 15.

The push rod 5 is slidably installed between the two first limiting rods 16. A one-way screw 17 is rotatably installed at the top center of the base 1 through a bearing. The one-way screw 17 is threadedly connected to the middle of the push rod 5. A first motor 18 is fixedly installed on one side of the base 1 at the position corresponding to the one-way screw 17. The output end of the first motor 18 is fixedly connected to one end of the one-way screw 17.

[0027] By controlling the first motor 18 to drive the one-way screw 17 to rotate, the one-way screw 17 is connected to the push rod 5 by a thread, thereby driving the push rod 5 to slide along the trajectory of the two first limit rods 16.

The bottom end of the upright 3 is fixedly installed with a slider 20, which is slidably connected to the sliding groove 19. The bottom end of the upright 3 is installed with a fastening bolt 21, which passes through the slider 20.

[0029] When polishing the outer diameter of tubes of different diameters, the upright rod 3 can be moved along the track of the slide groove 19 to adjust the distance between the V-shaped rods 4 on the two mounting seats 2, so as to control the tube body to be stably placed between the four V-shaped rods 4.

[0030] like Figures 1 to 4 As shown, a second limiting rod 22 is symmetrically fixedly installed inside the top of the base 1. The mounting seat 2 is slidably installed between the two second limiting rods 22. A bidirectional screw 23 is rotatably installed inside the top of the base 1 through a bearing.

[0033] When polishing the outer diameter of tubes of different diameters, the relative position between the wiping cloth 8 on the mounting plate 7 and the fixing plate 6 is adjusted by adjusting the setting of the adjusting bolt 25, so as to control the wiping cloth 8 to contact the outer diameter of the tube.

[0034] This utility model provides a device for polishing the outer diameter of a tube, the specific working principle of which is as follows:

[0035] In use, the tube is passed through four V-shaped rods 4 and wrapped around the tube by the V-shaped rods 4. The outer circumference of the tube contacts the wiping cloth 8, and the tube passes through the middle of the fixed cylinder 9. Two grinding motors 14 operate simultaneously, driving two grinding wheels 15 to rotate. During the rotation of the two grinding wheels 15, the outer circumference of the tube is polished. During this process, the first motor 18 drives the one-way screw 17 to rotate. The one-way screw 17 is threadedly connected to the push rod 5, which in turn drives the push rod 5 to slide along the trajectory of the two first limit rods 16, thus pushing the tube. The end will then drive the tube body to move during the polishing process, which facilitates the polishing of the tube body. During the polishing process of the outer circle of the tube body, the tube body will rotate under the rotation friction of the two grinding wheels 15. At the same time, the moving outer circle of the tube body will contact the wiping cloth 8 at the top of the fixed plate 6, which can clean the dust on the outer circle of the tube body and improve the convenience of polishing the outer circle of the tube body. Meanwhile, the tube body will pass through the middle of the fixed cylinder 9, and air will be introduced into the interior of the fixed cylinder 9 by the blower. The gas will be discharged from the air hole 12 through the cavity 10, which can further clean the dust on the outer circle of the tube body.

[0036] When polishing the outer diameter of tubes of different diameters, the second motor 24 drives the bidirectional screw 23 to rotate. The two ends of the bidirectional screw 23 are respectively connected to the threads in the middle of the two mounting seats 2, which will drive the two mounting seats 2 to move towards each other or away from each other along the trajectory of the two second limit rods 22, which can change the distance between the two grinding wheels 15. At the same time, the upright rod 3 moves along the trajectory of the slide groove 19, which can adjust the distance between the V-shaped rods 4 on the two mounting seats 2, so as to control the tube body to be stably placed between the four V-shaped rods 4. Meanwhile, the relative position between the wiping cloth 8 on the mounting plate 7 and the fixing plate 6 is adjusted by adjusting the setting of the adjusting bolt 25, so as to control the wiping cloth 8 to contact the outer diameter of the tube body.
