[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figure 1-5 This utility model provides a grinding device for polyimide tube production, including a fixed base plate 1. Two mounting brackets 2 are symmetrically fixedly connected to the top of one side of the fixed base plate 1. A fixed vertical plate 3 is fixedly connected between the two mounting brackets 2. A rotating disk 4 is rotatably connected to the middle of the fixed vertical plate 3. The rotating disk 4 can rotate in the middle of the fixed vertical plate 3. A transmission gear ring 5 is drivenly connected to one end of the rotating disk 4. A drive assembly is fixedly connected to one side of the fixed vertical plate 3. An internal port grinding assembly and an external port grinding assembly are rotatably connected to the middle of the rotating disk 4. An L-shaped frame 22 is fixedly connected to one side of the top of the fixed base plate 1. A clamping assembly is drivenly connected to the top of the L-shaped frame 22.
[0022] Furthermore, the drive assembly includes a mounting plate 6, which is fixedly connected to the side of a mounting bracket 2. A drive motor 8 is fixedly mounted on one end of the mounting plate 6. The output end of the drive motor 8 passes through the mounting plate 6 and is connected to a drive gear 7. The drive gear 7 meshes with a transmission gear ring 5. Before use, the drive motor 8 is connected to an external power supply control wire and a controller. After the drive motor 8 runs, it drives the drive gear 7 to rotate. The rotation of the drive gear 7 meshes with the transmission gear ring 5, causing the transmission gear ring 5 to rotate. The rotation of the transmission gear ring 5 causes the rotating disk 4 to rotate.
[0023] Furthermore, the internal port grinding assembly includes an active gear block 9, which is rotatably connected to the center of the rotating disk 4. An adjusting screw 12 is threadedly connected to the center of the active gear block 9. A sliding block 13 is fixedly connected to the end of the adjusting screw 12 away from the rotating disk 4. Two transmission arms 14 are symmetrically rotatably connected to the side of the sliding block 13 away from the adjusting screw 12. Two fixed brackets 10 are symmetrically fixedly connected to one end of the active gear block 9. Limiting grooves 11 are symmetrically formed on the sides of the two fixed brackets 10 that are close to each other. The sliding block 13 matches the limiting grooves 11. A fixed shaft 15 is internally fixedly connected to the end of the two fixed brackets 10 away from the active gear block 9. A first... The grinding frame 16 and the second grinding frame 18 are provided. The top of the first grinding frame 16 is fixedly connected to the first grinding block 17, and the bottom of the second grinding frame 18 is fixedly connected to the second grinding block 19. The second grinding block 19 and the first grinding block 17 have different grit sizes. When grinding pipes of different diameters, the adjusting screw 12 is rotated, and the adjusting screw 12 and the active tooth block 9 are screwed together, causing the sliding block 13 to slide along the limiting groove 11, thereby pushing the transmission arm 14. This causes the included angle between the two transmission arms 14 to change, thereby changing the included angle between the first grinding frame 16 and the second grinding frame 18 to adapt to the specifications of the inner port of the pipe, so that the second grinding block 19 and the first grinding block 17 contact the edge of the inner port of the pipe.
[0024] Furthermore, a rectangular through slot is provided in the middle of the first grinding frame 16, and the second grinding frame 18 matches the rectangular through slot. A positioning plate 28 is rotatably connected to the middle of the adjusting screw 12. A positioning bolt 29 is provided on the side of the positioning plate 28 away from the rotating plate 4. The positioning plate 28 and the active tooth block 9 are fixedly connected. The adjusting screw 12 passes through the positioning plate 28 and is threadedly connected to the active tooth block 9.
[0025] Furthermore, the external port grinding assembly includes two driven tooth blocks 20, which are symmetrically rotatably connected to the side of the rotating disk 4. Both driven tooth blocks 20 are meshed with the driving tooth block 9. An external port grinding frame 21 is fixedly connected to the end of each of the two driven tooth blocks 20. The two driven tooth blocks 20 and the external port grinding frame 21 are inclinedly distributed. Grinding blocks of different grit sizes are fixedly connected to the top and bottom surfaces of the external port grinding frame 21, respectively. When it is necessary to change the grinding blocks of different grit sizes fixedly connected to the top and bottom surfaces of the external port grinding frame 21, the positioning bolt 29 is turned to remove the positioning bolt 29 from the rotating disk 4, thereby releasing the limitation on the positioning disk 28. Then, the positioning disk 28 is rotated 180 degrees to complete the conversion of the grinding blocks of different grit sizes. Then, the positioning bolt 29 is turned in the opposite direction to screw it into the rotating disk 4, and grinding can begin.
[0026] Furthermore, the clamping assembly includes a lifting and adjusting stud 24, which is rotatably connected to the middle of the top of the L-shaped frame 22. An adjusting wheel 23 is fixedly connected to the top of the L-shaped frame 22. Two guide rods 25 are symmetrically fixedly connected inside the L-shaped frame 22. Two clamping blocks 26 are symmetrically slidably connected to the middle of the lifting and adjusting stud 24. Both clamping blocks 26 are threadedly connected to the L-shaped frame 22. Anti-slip pads 27 are fixedly installed on the side of the two guide rods 25 that are close to each other. The pipe to be ground is placed on the clamping block 26 at the bottom, so that it contacts the anti-slip pad 27. The adjusting wheel 23 is rotated, which drives the lifting and adjusting stud 24 to rotate. The rotation of the lifting and adjusting stud 24 engages with the two clamping blocks 26, so that the two clamping blocks 26 come close to each other and clamp the pipe.
[0027] When this application embodiment is used:
[0028] When grinding the pipe fitting, after the drive motor 8 runs, it drives the drive gear 7 to rotate. The rotation of the drive gear 7 meshes with the transmission gear ring 5, which in turn drives the transmission gear ring 5 to rotate. The rotation of the transmission gear ring 5 drives the rotating disk 4 to rotate. The rotation of the rotating disk 4 drives the first grinding frame 16, the second grinding frame 18, the second grinding block 19 and the first grinding block 17 to grind the inner edge of the pipe fitting. The outer end grinding frame 21 grinds the outer end of the pipe fitting.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
