[0025] Please see Figures 1-5 In this embodiment of the present invention, an intermediate shaft surface polishing device includes a first housing 1. An operation port 2 is provided on one side wall of the first housing 1. A first electric telescopic rod 16 is vertically fixedly connected to the center of the top of the first housing 1. A third housing 14 is fixedly connected to the output end of the first electric telescopic rod 16. An inverted U-shaped frame 17 is provided at the lower end of the third housing 14.

Two limiting frames 10 are fixedly connected to the lower end of the inverted U-shaped frame 17. The limiting frames 10 are parallel to the operation port 2. The inner walls of the limiting frames 10 are... A support plate 12 is slidably connected, and several sandpaper fixing plates 25 for attaching and fixing sandpaper of different roughness are fixedly connected to the lower end of the support plate 12. Sandpaper of different roughness is attached and fixed to the several sandpaper fixing plates 25. A switching mechanism for moving the support plate 12 is provided on the inner wall of the first box 1. Two parallel sliding rods 6 are horizontally fixedly connected to the inner wall of the first box 1 directly below the inverted U-shaped frame 17. The lower end of the sliding rods 6 is on the same horizontal plane as the operation port 2, and the sliding rods 6 and the operation port 2 are parallel to each other. A clamping mechanism for fixing and rotating the intermediate shaft is provided on the sliding rods 6.

[0026] The clamping mechanism includes two moving blocks 3, which are slidably sleeved on the side wall of the slide rod 6. The upper end of each moving block 3 is fixedly connected to a second housing 4. Each of the two second housings 4 is provided with a chuck 5 for clamping and fixing the end of the intermediate shaft at one end close to each other. A rotating rod 19 is fixedly connected to the center of the end of the chuck 5 close to the second housing 4. The end of the rotating rod 19 away from the chuck 5 is rotatably connected to the inner wall of the second housing 4. A motor 20 is fixedly connected inside one of the second housings 4. The output end of the motor 20 is fixedly connected to the end of the rotating rod 19 away from the chuck 5. The center point of the two chucks 5 is located directly below the center of the inverted U-shaped frame 17. A moving component for driving the intermediate shaft to move is provided below the slide rod 6.

[0027] The moving component includes a linear moving module 8, with both ends of the linear moving module 8 horizontally fixed to the inner wall of the first housing 1 below the slide rod 6. The linear moving module 8 and the slide rod 6 are parallel to each other. The output end of the linear moving module 8 faces the bottom of the first housing 1. A connecting rod 7 is fixedly connected to the lower end of one of the moving blocks 3. The end of the connecting rod 7 away from the moving block 3 is fixedly connected to the output end of the linear moving module 8. A gap is provided between the upper end of the linear moving module 8 and the lower end of the moving block 3 to facilitate cleaning debris from the upper end of the linear moving module 8.

[0028] In use, the movable block 3, which is not connected to the connecting rod 7, is moved. The movable block 3 drives the second housing 4 and the chuck 5 to move, thereby clamping and fixing the two ends of the intermediate shaft with the two chucks 5. Then, the linear motion module 8 is started. The output end of the linear motion module 8 drives the connecting rod 7 to move. Due to the fixation of the intermediate shaft, the connecting rod 7 drives the two movable blocks 3, the second housing 4, and the chuck 5 to move together.

[0029] Start motor 20. The output end of motor 20 drives rotating rod 19 to rotate. Rotating rod 19 drives chuck 5 to rotate. Chuck 5 drives intermediate shaft to rotate.

[0030] The pressure measuring mechanism includes a pressure sensor 21, which is fixedly connected to the top of the third housing 14. A first moving plate 22 is fixedly connected to the measuring end of the pressure sensor 21. A spring 23 is fixedly connected to the lower end of the first moving plate 22. A second moving plate 24 is fixedly connected to the lower end of the spring 23. A fixing column 11 is fixedly connected to the lower end of the second moving plate 24. The end of the fixing column 11 away from the second moving plate 24 passes through the bottom of the third housing 14 and is fixedly connected to the upper end of the inverted U-shaped frame 17.

[0031] When in use, the first electric telescopic rod 16 is activated to extend. The output end of the first electric telescopic rod 16 drives the third housing 14 to move downward. The third housing 14 drives the fixed column 11 to move downward. The fixed column 11 drives the inverted U-shaped frame 17 and the limiting frame 10 to move downward. The limiting frame 10 drives the support plate 12 and the sandpaper fixing plate 25 to move downward, so that the sandpaper fixing plate 25 is pressed tightly against the side wall of the intermediate shaft.

[0032] Since the forces are mutual, the sandpaper fixing plate 25 and the support plate 12 push the limiting frame 10, the inverted U-shaped frame 17 and the fixing column 11 upward. The fixing column 11 pushes the second moving plate 24 to compress the spring 23. The spring 23 squeezes the first moving plate 22. The first moving plate 22 squeezes the measuring end of the pressure sensor 21, so that the pressure sensor 21 can measure the pressure value of the sandpaper fixing plate 25 on the intermediate shaft.

[0033] The switching mechanism includes a sliding sleeve 13, which is vertically fixed to one end of the support plate 12 away from the operation port 2. A fixing rod 9 is slidably sleeved on the inner wall of the sliding sleeve 13. A fixing block 15 is fixedly connected to the upper end of the fixing rod 9. A second electric telescopic rod 18 is horizontally fixedly connected to the inner wall of the first housing 1 above the operation port 2. The second electric telescopic rod 18 is parallel to the support plate 12. The output end of the second electric telescopic rod 18 is fixedly connected to the side wall of the fixing block 15.

[0034] When in use, the second electric telescopic rod 18 is activated. The output end of the second electric telescopic rod 18 drives the fixed block 15 to move. The fixed block 15 drives the fixed rod 9 to move. The fixed rod 9 drives the sliding sleeve 13 to move. The sliding sleeve 13 drives the support plate 12 to move along the inner wall of the limiting frame 10, thereby changing the position of the sandpaper fixing plate 25 between the two limiting frames 10, and thus realizing the switching of sandpaper with different roughness.

[0035] Working principle of an intermediate shaft surface polishing device:

[0036] Before use, start the second electric telescopic rod 18. The output end of the second electric telescopic rod 18 drives the fixed block 15 to move. The fixed block 15 drives the fixed rod 9 to move. The fixed rod 9 drives the sliding sleeve 13 to move. The sliding sleeve 13 drives the support plate 12 to move along the inner wall of the limit frame 10, thereby changing the position of the sandpaper fixing plate 25 between the two limit frames 10 and selecting the sandpaper with the required roughness.

[0037] In use, the operator moves the movable block 3 that is not connected to the connecting rod 7. The movable block 3 moves the second housing 4 and the chuck 5, thereby clamping and fixing the two ends of the intermediate shaft with the two chucks 5. Then, the linear motion module 8 is started. The output end of the linear motion module 8 drives the connecting rod 7 to move. Due to the fixation of the intermediate shaft, the connecting rod 7 drives the two movable blocks 3, the second housing 4, and the chuck 5 to move together, moving one end of the intermediate shaft to directly below the inverted U-shaped frame 17. At the same time, the motor 20 is started. The output end of the motor 20 drives the rotating rod 19 to rotate. The rotating rod 19 drives the chuck 5 to rotate, and the chuck 5 drives the intermediate shaft to rotate.

[0038] Then, the first electric telescopic rod 16 is activated to extend. The output end of the first electric telescopic rod 16 drives the third housing 14 to move downward. The third housing 14 drives the fixed column 11 to move downward. The fixed column 11 drives the inverted U-shaped frame 17 and the limiting frame 10 to move downward. The limiting frame 10 drives the support plate 12 and the sandpaper fixing plate 25 to move downward, so that the sandpaper fixing plate 25 is pressed tightly against the side wall of the intermediate shaft.

[0039] Since the forces are mutual, the sandpaper fixing plate 25 and the support plate 12 push the limiting frame 10, the inverted U-shaped frame 17 and the fixing column 11 upward. The fixing column 11 pushes the second moving plate 24 to compress the spring 23. The spring 23 squeezes the first moving plate 22. The first moving plate 22 squeezes the measuring end of the pressure sensor 21, so that the pressure sensor 21 measures the pressure value of the sandpaper fixing plate 25 on the intermediate shaft and makes the pressure value reach the set value.

[0040] Then, the linear motion module 8 is activated. The output end of the linear motion module 8 drives the connecting rod 7 to move. Due to the fixation of the intermediate shaft, the connecting rod 7 drives the two moving blocks 3, the second housing 4, and the chuck 5 to move together, thereby polishing the intermediate shaft.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
