A grinding assembly is provided at one end of the top outer wall of the base 1, and a fixing assembly 4 is provided at the other end of the base 1. The grinding assembly includes a fixing frame 2 and a rotating disk 3. The fixing frame 2 is fixed to the top outer wall of the base 1. The rotating disk 3 is disposed on one side of the rotating disk 3. A rotating shaft 6 is fixed to one side of the rotating disk 3. The rotating shaft 6 is rotatably connected to the fixing frame 2. A rotating motor is installed on one side outer wall of the fixing frame 2. The output shaft of the rotating motor is transmitted to the rotating shaft 6 through a gear transmission assembly 7. A guide groove 5 is formed on one side outer wall of the rotating disk 3. A threaded rod 8 and a connecting rod 8 are rotatably connected to the inner wall of the guide groove 5. The connecting rod 12 has a sliding block 9 on the inner wall of the guide groove 5. The sliding block 9 is threaded to the outer wall of the threaded rod 8. A guide frame 10 is provided on the side wall of the sliding block 9. A bidirectional screw 11 is rotatably connected to the inner wall of the guide frame 10. Two mounting blocks 13 are slidingly fitted on the inner wall of the guide frame 10. The two mounting blocks 13 are threaded to the outer walls of both ends of the bidirectional screw 11. A grinding motor is installed inside the mounting block 13. A grinding head is fixedly connected to the output shaft of the grinding motor. The connecting rod 12 is vertically slidingly fitted to the inner wall of the bidirectional screw 11. Two adjusting motors that drive the threaded rod 8 and the connecting rod 12 to rotate are installed inside the rotating disk 3.

[0028] The fixing component 4 includes a fixing ring 14 and multiple threaded rods 15. The fixing ring 14 is fixed to the top outer wall of the base 1. The multiple threaded rods 15 are arranged circumferentially around the axis of the fixing ring 14. The threaded rods 15 are vertically slidingly engaged with the fixing ring 14. A fixing plate 16 is fixedly connected to one end of the threaded rod 15. Multiple threaded cylinders 17 are rotatably connected to the inner wall of the fixing ring 14. The threaded cylinders 17 are threadedly engaged with the threaded rods 15. A driven bevel gear 18 is fixed to the outer wall of the threaded cylinder 17. A driving bevel gear 19 is driven and meshed on one side of the driven bevel gear 18. A drive motor is installed on one side of the outer wall of the fixing ring 14. The output shaft of the drive motor drives the driving bevel gear 19 through a gear-ring drive.

[0029] During grinding, one adjusting motor drives the threaded rod 8 to rotate, causing the moving block 9 to move along the guide groove 5. The distance between the grinding head and the axis of the rotating disk 3 is changed according to the diameter of the metal tube. Then, another adjusting motor drives the connecting rod 12 to rotate, which drives the bidirectional screw 11 to rotate, causing the two mounting blocks 13 to move towards or away from each other along the bidirectional screw 11, changing the distance between the two grinding heads. This allows the wall of one end of the metal tube to be inserted between the two grinding heads. Then, the metal tube is inserted into the fixing ring 14, with the wall of one end of the metal tube entering between the two grinding heads. The driving motor drives the active bevel gear 19 to rotate, and through the transmission of the active bevel gear 19 and the driven bevel gear 18, multiple threaded cylinders 17 rotate synchronously, causing the threaded rod 15 to move towards the axis of the fixing ring 14. Multiple fixing plates 16 fix the metal tube. Then, the adjusting motor drives the connecting rod 12 to rotate, causing the two grinding heads to contact the inner and outer walls of the metal tube. The grinding motor drives the grinding head to rotate for grinding, and at the same time, the rotating motor drives the rotating disk 3 to rotate through the transmission of the gear transmission assembly 7.

[0030] By setting up a grinding component, the position of the grinding motor can be adjusted according to the diameter and wall thickness of the metal tube, making it convenient to grind the ends of metal tubes of different specifications.

[0031] By setting multiple threaded rods 15 and fixing plates 16, the metal pipe is fixed at multiple points, making the fixation more stable.

[0032] Example 2

[0033] A metal pipe end burr grinding device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 4 As shown, an extension rod 20 is slidably connected to the inner wall of the base 1. A guide cylinder 21 is fixed to one end of the extension rod 20. A rotating ring 22 is rotatably connected to the top of the guide cylinder 21. A support rod 23 is provided on the inner wall of the guide cylinder 21. The support rod 23 includes a threaded rod 3 that slides vertically with the inner wall of the guide cylinder 21 and a support plate. The threaded rod 3 is threadedly engaged with the rotating ring 22. A limiting rod 24 that is inserted into the base 1 is provided on one side of the extension rod 20. Multiple limiting holes that limit the limiting rod 24.

[0034] When the metal tube is long, after the metal tube is fixed, the limiting rod 24 can be pulled out to one side to disengage from the extension rod 20. The extension rod 20 can be pulled out to one side to adjust the distance between the support rod 23 and the fixing component 4. Then the limiting rod 24 can be inserted back to limit the extension rod 20. The rotating ring 22 can be rotated to make the support rod 23 rise to support the metal tube.

[0035] By incorporating an extension rod 20, a guide cylinder 21, a rotating ring 22, a support rod 23, and a limiting rod 24, the metal tube can be supported when it is long, thus preventing the metal tube from tilting due to its own weight.

[0036] Working principle: During grinding, one adjusting motor drives the threaded rod 8 to rotate, causing the moving block 9 to move along the guide groove 5. This changes the distance between the grinding head and the axis of the rotating disk 3 according to the diameter of the metal tube. Then, another adjusting motor drives the connecting rod 12 to rotate, which in turn drives the bidirectional screw 11 to rotate. This causes the two mounting blocks 13 to move towards or away from each other along the bidirectional screw 11, changing the distance between the two grinding heads. This allows the wall of one end of the metal tube to be inserted between the two grinding heads. The metal tube is then inserted into the fixing ring 14, with the wall of one end of the metal tube entering between the two grinding heads. The driving motor then drives the active bevel gear 19 to rotate, which, through the transmission between the active bevel gear 19 and the driven bevel gear 18, drives multiple threaded cylinders. 17. The screw rod 15 moves synchronously towards the axis of the fixing ring 14, and multiple fixing plates 16 fix the metal tube. Then, the motor drives the connecting rod 12 to rotate, so that the two grinding heads contact the inner and outer walls of the metal tube. The grinding motor drives the grinding heads to rotate for grinding. At the same time, the rotating motor drives the rotating disk 3 to rotate through the gear transmission assembly 7. When the metal tube is long, after the metal tube is fixed, the limiting rod 24 can be pulled out to one side to disengage from the extension rod 20. The extension rod 20 is pulled out to one side, and the distance between the support rod 23 and the fixing assembly 4 is adjusted. Then, the limiting rod 24 is inserted back to limit the extension rod 20. The rotating ring 22 is rotated to make the support rod 23 rise to support the metal tube.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
