[0003] At present, some electronic product housings are mostly made of metal, and most metal housings are formed by molds. After the metal housings are formed, the surface roughness is relatively high, and the surface needs to be polished. Since the outer surface of some metal housings has a main surface and four side surfaces that all need to be polished, the existing polishing machines can only polish one surface at a time during use, resulting in slow polishing speed and low efficiency. Therefore, in view of the current situation, it is necessary to improve it now. Content of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] It is given by Figures 1 to 4 The present invention includes a machine base 1. A first installation groove 2 is opened at the top of the machine base 1. A second installation groove 3 is opened on one side of the first installation groove 2. A protective cover 4 is fixedly installed at the top of the machine base 1 and above the second installation groove 3. Both ends inside the first installation groove 2 are rotatably installed with first rotating cylinders 5. A first grinding sand belt 6 is installed between the two first rotating cylinders 5. Second rotating cylinders 7 are rotatably installed inside the second installation groove 3 and at the upper part inside the protective cover 4. A second grinding sand belt 8 is installed between the two second rotating cylinders 7. A transmission groove 9 is opened inside one end of the machine base 1. A motor 10 is installed inside the transmission groove 9. One end of one of the first rotating cylinders 5 and one end of one of the second rotating cylinders 7 both extend into the transmission groove 9 and are in transmission connection with the output end of the motor 10.

[0020] A large gear 11 is fixedly installed at the output end of the motor 10. One end of one of the second rotating cylinders 7 extends into the transmission groove 9 and is fixedly installed with a first bevel gear 12 and a small gear 13. The small gear 13 is meshed with the large gear 11, so as to effectively adjust the acceleration rotation of the second rotating cylinder 7; a square cavity 14 is opened in the middle of one of the first rotating cylinders 5. A pipe 15 is installed between the first installation groove 2 and the transmission groove 9. A square rod 16 is installed inside the square cavity 14. One end of the square rod 16 is fixedly installed with a rotating shaft 17. One end of the rotating shaft 17 penetrates through the pipe 15 and extends into the transmission groove 9 and is fixedly installed with a second bevel gear 18. The second bevel gear 18 is meshed with the first bevel gear 12, so as to effectively adjust the rotation of the first grinding sand belt 6 and the second grinding sand belt 8.

[0021] The large gear 11 is rotated by starting the motor 10. The rotation of the large gear 11 drives and accelerates the rotation of the small gear 13. The rotation of the small gear 13 drives the rotation of one of the second rotating cylinders 7 and the first bevel gear 12. The rotation of one of the second rotating cylinders 7 drives the rotation of the second grinding sand belt 8 through the other second rotating cylinder 7; the rotation of the first bevel gear 12 drives the rotation of the second bevel gear 18. The rotation of the second bevel gear 18 drives the rotation of the rotating shaft 17. The rotation of the rotating shaft 17 drives the rotation of one of the first rotating cylinders 5 through the square rod 16 and the square cavity 14. The rotation of one of the first rotating cylinders 5 drives the rotation of the first grinding sand belt 6 through the other first rotating cylinder 5;

[0022] Then the worker places the main surface of the metal shell downward on the first grinding sand belt 6 for grinding operation. At the same time, through the operation of the worker, the metal shell is rotated so that the four side surfaces of the metal shell are sequentially in contact with the second grinding sand belt 8 for grinding operation.

[0023] An internally threaded pipe 19 is fixedly installed between one side of the machine base 1 and the first installation groove 2. A threaded adjusting rod 20 is threadedly connected inside the internally threaded pipe 19. One end of the threaded adjusting rod 20 extends into the interior of the square cavity 14 and is connected to the square rod 16 through a bearing. The other end of the threaded adjusting rod 20 is fixedly installed with a rotating wheel 21, so that the square rod 16 can be effectively adjusted;

[0024] When only the second grinding sand belt 8 needs to rotate for grinding operation, rotate the rotating wheel 21 to make the threaded adjusting rod 20 rotate and move inside the internally threaded pipe 19. The movement of the threaded adjusting rod 20 will pull the square rod 16 to move. The movement of the square rod 16 will pull the rotating shaft 17 and the second bevel gear 18 to move, so that the second bevel gear 18 is separated from the first bevel gear 12. At this time, when the motor 10 is started, only the second grinding sand belt 8 rotates;

[0025] A cross pin 22 is inserted into the surface of the rotating wheel 21. A spring 23 is installed in the middle of the cross pin 22. One end of the cross pin 22 is fixedly installed with a pull ring 24. A jack 25 is opened on one side of the machine base 1. The other end of the cross pin 22 is inserted into the interior of the jack 25, so that the adjustment stability of the threaded adjusting rod 20 can be effectively ensured; when the square rod 16 rotates, the square rod 16 may drive the threaded adjusting rod 20 to rotate during the high-speed rotation process. In order to keep the threaded adjusting rod 20 stable, the other end of the cross pin 22 is inserted into the interior of the jack 25 to make the rotating wheel 21 unable to rotate. The non-rotation of the rotating wheel 21 will keep the threaded adjusting rod 20 effectively stable.

[0026] One end of one of the second rotating cylinders 7 extends outside one end of the machine base 1 and is fixedly installed with an adjusting wheel 26. One end of the machine base 1 is fixedly installed with a sector-shaped protective shell 27. The adjusting wheel 26 is located inside the sector-shaped protective shell 27, so that the first bevel gear 12 can be effectively adjusted, enabling the first bevel gear 12 to be effectively meshed and connected with the second bevel gear 18. When the second bevel gear 18 moves towards the first bevel gear 12 and cannot be meshed with the first bevel gear 12, the first bevel gear 12 is driven to rotate by rotating one of the second rotating cylinders 7 through the adjusting wheel 26, so that the first bevel gear 12 can be effectively meshed and connected with the second bevel gear 18.

[0027] This metal product surface treatment device can perform grinding operations on the main surface and side surface of the outer surface of the metal shell during a single grinding operation, thus effectively improving the speed and efficiency of surface treatment. At the same time, it also effectively improves the speed and efficiency of metal shell processing. Moreover, the grinding operation of this metal product surface treatment device is simple and convenient, and it is stable and reliable in use. Its performance can meet the usage requirements of metal shell surface processing.
