[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1: As Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an automated grinding device for powder box plastic parts, including a workbench 1, a support frame 2 fixedly connected to the surface of the workbench 1, a hydraulic rod 3 fixedly connected to the surface of the support frame 2, a motor 4 fixedly connected to the output end of the hydraulic rod 3, a cross-shaped fixing frame 5 fixedly connected to the output end of the motor 4, a grinding disc 6 fixedly connected to the inner side of the cross-shaped fixing frame 5, a clamping mechanism provided on the surface of the workbench 1, the clamping mechanism including an electric push rod 7, a fixing block 8 fixedly connected to the output end of the electric push rod 7, a square block 10 inserted into the inner side of the fixing block 8, a clamping plate 9 fixedly connected to the surface of the square block 10, a sleeve 11 fixedly connected to the surface of the fixing block 8, a pin 12 slidably connected inside the sleeve 11, a pull rod 13 fixedly connected to the surface of the pin 12, and a pull rod 13... A spring 14 is fitted onto the surface of the block 10. A slot 15 is opened on the surface of the block 10. A pin 12 is inserted into the slot 15. A magnet 16 is fixedly connected inside the slot. The magnet 16 is magnetically connected to the pin 12. A protective pad 28 is fixedly connected to the surface of the clamping plate 9. The protective pad 28 is made of elastic rubber. There are two sets of electric push rods 7. The two sets of electric push rods 7 are symmetrically distributed on both sides of the middle of the grinding disc 6. A T-shaped rod 17 is fixedly connected to the surface of the protective pad 28. A T-shaped groove 18 is opened on the surface of the clamping plate 9. The T-shaped rod 17 is slidably connected inside the T-shaped groove 18. The T-shaped rod 17 is made of the same material as the protective pad 28. A vacuum cleaner 25 is fixedly connected to the lower surface of the workbench 1. A pipe 26 is fixedly connected to the surface of the vacuum cleaner 25. A dust collection cover 27 is fixedly connected to the other end of the pipe 26.
[0026] In this embodiment, the electric push rod 7 pushes the clamping plate 9 to clamp and fix the item to be polished, preventing the item from shifting due to shaking during polishing. This helps improve the quality of polishing and facilitates the smooth progress of the polishing work. At the same time, by pulling the pull rod 13 upward, the pull rod 13 drives the pin 12 to slide inside the sleeve 11 and squeeze the spring 14, causing the pin 12 to disengage from the inside of the block 10 and allowing the clamping plate 9 to be disassembled. This enables the clamping plate 9 to be quickly disassembled and replaced according to the shape of the item, further improving the stability of fixing items of different shapes. The protective pad 28 contacts the surface of the item, which not only prevents the clamping plate 9 from damaging the item, but also further increases the stability of fixing the item. By starting the vacuum cleaner 25, the dust generated during the polishing process can be sucked into the vacuum cleaner 25 through the dust collection hood 27 and the pipe 26, preventing the generation of dust.
[0027] Example 2: As Figure 3 - Figure 4As shown, the surface of the grinding disc 6 is provided with a fixing groove 21 and a slot 2 19. The surface of the cross fixing bracket 5 is fixedly connected with a threaded tube 22. The threaded tube 22 is threadedly connected with a screw 23. One end of the screw 23 is fixedly connected with an adjustment knob 24. The other end of the screw 23 is inserted into the inside of the fixing groove 21. The lower surface of the cross fixing bracket 5 is fixedly connected with a plug rod 20. The plug rod 20 is inserted into the inside of the slot 2 19.
[0028] In this embodiment, by rotating the adjustment knob 24, the screw 23 rotates inside the threaded tube 22, releasing the cross-shaped fixing bracket 5 from fixing the grinding disc 6. This makes the disassembly and assembly of the grinding disc 6 simpler and more convenient, allowing for the replacement of different grinding discs 6 according to the required level of grinding fineness. This further improves the practicality and applicability of the device. When installing the grinding disc 6, by inserting the insert rod 20 on the cross-shaped fixing bracket 5 into the slot 19 on the grinding disc 6, the fixing slot 21 can be quickly aligned with one end of the screw 23, further improving the convenience of fixing the grinding disc 6.
[0029] The working principle of this embodiment is as follows: In use, the powder box to be polished is first placed between the two sets of clamping plates 9. Then, the electric push rod 7 is activated, which pushes the clamping plates 9 to clamp and fix the item to be polished, preventing the item from shifting due to shaking during polishing. This improves the quality of polishing and facilitates the smooth progress of the polishing work. Simultaneously, by pulling the pull rod 13 upwards, the pull rod 13 causes the pin 12 to slide inside the sleeve 11 and compress the spring 14, causing the pin 12 to disengage from the inside of the block 10, allowing for the disassembly of the clamping plates 9. This achieves the goal of... The clamping plate 9 can be quickly disassembled and replaced according to the shape of the item, further improving the stability of fixing items of different shapes. Then, the hydraulic rod 3 on the support frame 2 is activated. The output of the hydraulic rod 3 pushes the motor 4 and the grinding disc 6 downwards. The motor 4 is then activated, and its output drives the grinding disc 6 to rotate and grind the surface of the powder box. The protective pad 28 contacts the surface of the item, which not only prevents the clamping plate 9 from damaging the item but also further increases the stability of fixing the item. While grinding the powder box, the vacuum cleaner 25 can be activated to clean the surface. Dust generated during the polishing process is sucked into the vacuum cleaner 25 through the dust collection hood 27 and pipe 26, preventing dust from being stirred up. When the polishing disc 6 needs to be replaced, the adjusting knob 24 is turned, which drives the screw 23 to rotate inside the threaded tube 22, releasing the cross-shaped fixing bracket 5 from the polishing disc 6. This makes the disassembly and assembly of the polishing disc 6 simpler and more convenient, allowing for the replacement of different polishing discs 6 according to the required polishing fineness. This further improves the practicality and applicability of the device. When installing the polishing disc 6, the cross-shaped fixing bracket 5 is used to... Inserting the insert rod 20 into the slot 19 on the grinding disc 6 allows the fixing slot 21 to quickly align with one end of the screw 23, further improving the convenience of fixing the grinding disc 6. When fixing the clamping plate 9, the pin 12 is magnetically attracted to the magnet 16 in the slot 15, which further improves the stability of the pin 12 in the slot 15. When the protective pad 28 needs to be replaced, the T-shaped rod 17 on the protective pad 28 is pulled upward to disengage it from the T-shaped groove 18 on the clamping plate 9, and then a new protective pad 28 can be replaced.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
