[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a shaft-extending device for surface polishing. (Refer to...) Figure 1-6A surface polishing shaft-extending device includes a polishing box 1, a movable frame 2 and a moving assembly for driving the movable frame 2 to move inside the polishing box 1. The moving assembly includes a mounting frame 10, a lead screw 11, a motor 12, a guide rod 13, a slider 14, a lead screw 15, a gear 16, a gear 17, a fixed frame 18, a motor 19, and a guide rod 20. The mounting frame 10 is fixed to both sides of the inner wall of the polishing box 1. The lead screw 11 rotates within the mounting frame 10, and the motor 12 is fixed to the inner wall of the polishing box 1. On one side of mounting bracket 10, the rotor end of motor 2 12 is fixed to lead screw 11, and guide rod 13 is fixed inside mounting bracket 10. Two sets of sliders 14 slide within the two mounting brackets 10 respectively. One set of sliders 14 is threadedly connected to lead screw 11, and the other set of sliders 14 can slide on the surface of guide rod 13. Lead screw 2 15 rotates on the side where two sliders 14 are close to each other, and guide rod 2 20 is fixed on the side where the other two sliders 14 are close to each other. Lead screw 2 15 is connected to movable bracket 2. The moving frame 2 is slidable on the surface of the guide rod 20 via a threaded connection. Gear 16 is fixed to one end of the lead screw 15, and gear 27 rotates on one side of a slider 14. A fixed frame 18 is fixed on the slider 14, and motor 3 19 is fixed on the fixed frame 18. The rotor end of motor 3 19 is fixed to gear 2 17. Gear 16 and gear 2 17 mesh. Starting motor 2 12 causes lead screw 11 to rotate. Under the guidance of guide rod 13, slider 14 drives lead screw 2 15 and guide rod 20 to reciprocate along the axis of guide rod 13 within the polishing box 1. Starting motor 3 19 causes gear 2 17 to drive gear 16 and lead screw 2 15 to rotate. Under the guidance of guide rod 20, moving frame 2 reciprocates along the axis of guide rod 20. Guide rod 20 and guide rod 13 are set perpendicularly. Through the flexible movement of moving frame 2, the grinding position of the workpiece can be flexibly adjusted to meet the grinding needs of products of different sizes and shapes.

[0027] Reference Figure 1-3The movable frame 2 is equipped with multiple placement platforms 4 and an adjustment assembly for simultaneously tilting the multiple placement platforms 4. The adjustment assembly includes a rotating plate 3, a rotating shaft 6, a worm gear 7, a worm 8, and a motor 9. The top of the movable frame 2 has a rotating groove 5. The rotating plate 3 is fixed to the bottom of the placement platform 4. Multiple rotating shafts 6 rotate within the rotating groove 5 and are evenly spaced. One end of each rotating shaft 6 is fixed with a worm gear 7. The worm 8 rotates within the rotating groove 5. The motor 9 is fixed to one side of the inner wall of the rotating groove 5. The rotor end of the motor 9 is fixed to the worm 8. The worm 8 meshes with multiple worm gears 7 simultaneously. The rotating shaft 6 passes through the rotating plate 3 and is fixed to the rotating plate 3. The placement platform 4 is equipped with a vacuum extraction pipe connected to the output end of a vacuum pump. The vacuum extraction pipe controls the vacuum pump's on / off cycle through an angle seat valve and controls the vacuuming time through a solenoid valve. The workpiece to be polished is placed on top of the placement platform 4, and the vacuum pump is turned on to adsorb and fix the workpiece. When it is necessary to polish a workpiece with a complex curved surface or an irregular shape, the motor 9 is started to rotate the worm gear 8, which in turn drives multiple worm wheels 7 and the placement platform 4 on the rotating plate 3 to tilt at an angle. This allows the placement platform 4 to better adapt to workpieces of different shapes and sizes, and at the same time, it allows the polishing disc 36 to fit more closely to the workpiece surface, improving polishing efficiency and quality.

[0028] Reference Figure 5 The polishing box 1 also includes a grinding assembly and a lifting assembly for driving the grinding assembly to rise and fall. The grinding assembly includes a grinding frame 35 and a grinding disc 36. The grinding frame 35 is fixed to the lifting assembly, and the grinding disc 36 can rotate on the grinding frame 35. The grinding frame 35 is equipped with a drive motor for driving the grinding disc 36 to rotate. The number of grinding discs 36 is the same as the number of placement tables 4. The lifting assembly includes a support frame 30, a lead screw 32, a motor 33, and a connecting block 34. The support frame 30 is fixed to one side of the inner wall of the polishing box 1, and a guide groove 31 is provided on the support frame 30. The connecting block 34... Sliding within the guide groove 31, the connecting block 34 is fixed to the grinding frame 35, the lead screw 32 rotates within the guide groove 31, and the lead screw 32 is threadedly connected to the connecting block 34. The motor 4 33 is fixed to the top of the support frame 30, and the rotor end of the motor 4 33 is fixed to the lead screw 32. When the motor 4 33 is started, the lead screw 32 rotates, and under the guidance of the guide groove 31, the connecting block 34 drives the grinding frame 35 and its grinding disc 36 to rise and fall, coordinating with the movement of the moving frame 2 to perform efficient grinding of the workpiece. During grinding, the drive motor is started to rotate the grinding disc 36 to achieve grinding of the workpiece.

[0029] Reference Figure 1-4The polishing box 1 has a water tank 25 on top. Inside the polishing box 1 is a spray assembly that communicates with the bottom of the water tank 25. The spray assembly includes an electric push rod 21, a support plate 22, spray pipes 23, and a diversion pipe 24. The electric push rod 21 is fixed to the top of the movable frame 2, and the telescopic end of the electric push rod 21 is fixed to the support plate 22. One end of the spray pipe 23 is connected to the diversion pipe 24, and the other end of the spray pipe 23 passes through the support plate 22 and is connected to a spray head. The number of spray pipes 23 is the same as the number of placement platforms 4. The diversion pipe 24 is fixed. At the top of the inner wall of the polishing box 1, the diversion pipe 24 is connected to the bottom of the water tank 25 through the connecting pipe. The part of the spray pipe 23 between the support plate 22 and the diversion pipe 24 is flexible. During polishing, the spray head is opened simultaneously. The water in the water tank 25 flows into the diversion pipe 24 through the connecting pipe and is distributed to each spray pipe 23. The spray head sprays water onto the workpiece from above the placement table 4. This can reduce the damage to the workpiece and the machine itself caused by the high temperature generated during polishing, and also effectively prevent waste chips from contaminating the surface of the finished product.

[0030] It should be noted that the bottom of the mobile frame 2 is hollowed out to facilitate the flow of spray water.

[0031] Reference Figure 4 The polishing box 1 is also equipped with a water circulation component that communicates with the side wall of the water tank 25. The water circulation component includes a circulating water pipe 26, a water pump 27, a filter box 28, and a return water pipe 29. One end of the circulating water pipe 26 is connected to the side wall of the water tank 25, and the other end of the circulating water pipe 26 extends into the filter box 28. The filter box 28 is fixed to one side of the outer wall of the polishing box 1. One end of the return water pipe 29 is connected to the bottom of the filter box 28, and the other end of the return water pipe 29 is connected to the bottom of the polishing box 1. The water pump 27 is fixed to the top of the polishing box 1, and the output end of the water pump 27 is fixed to the end of the circulating water pipe 26 near the water tank 25. The sprayed water flows into the bottom of the polishing box 1. When the water pump 27 is started, the sprayed water is drawn from the return water pipe 29 into the filter box 28. After the residue is filtered, it is fed back into the water tank 25 through the circulating water pipe 26 for recycling. This realizes the recycling and reuse of water resources, which saves costs and protects the environment.
