[0002] Precision abrasives are tools used for high-precision machining. These tools are used to finely process workpieces to achieve high levels of surface finish and dimensional accuracy. During this process, graded polishing and grinding devices are used to ensure optimal surface quality and precision. Graded polishing and grinding devices typically include multiple grinding or polishing stages, each using abrasive grains of different sizes to progressively improve the workpiece's surface quality.

[0003] Traditional graded polishing and grinding devices typically use a screw to move a clamping plate to hold and fix the workpiece, and then an electric motor drives the abrasive or polishing disc to treat the surface of the workpiece. However, the traditional method does not take into account the cumbersome process of moving the clamping plate by twisting the screw during the workpiece fixing process. Therefore, a precision abrasive graded polishing and grinding device is proposed to solve the above problems. Utility Model Content

[0007] A base is used to support the overall equipment and provide installation positions for other components. A placement plate is fixedly connected to the upper surface of the base, and an electric slide rail is provided inside the placement plate.

[0026] 1. In this utility model, the rotating block is driven to rotate by starting the motor, which in turn drives the connecting rod to move. One end of the connecting rod rotates and deflects on the surface of the rotating block, while the other end rotates on the surface of the limiting block and pulls it to slide along the slide groove towards the center. Finally, the workpiece is clamped and fixed by the clamping plate, which achieves the effect of fixing workpieces of different sizes and improves the practicality of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of a precision abrasive graded polishing and grinding device, comprising: a base 1, which supports the overall equipment and provides installation positions for other components; a placement plate 2 is fixedly connected to the upper surface of the base 1, and an electric slide rail 14 is provided inside the placement plate 2; a fixing mechanism, which is disposed on the top of the placement plate 2 and is used to fix square workpieces of different sizes; the fixing mechanism includes a fixing plate 3, a motor 4 is fixedly connected to the side wall of the fixing plate 3, a fixing plate 5 is fixedly connected to the side wall of the fixing plate 3, and multiple sliding grooves 6 are opened inside the fixing plate 5; a rotating block 7 is fixedly connected to the output end of the motor 4, and the side wall of the rotating block 7 rotates. Connected inside the fixed plate 5, the side wall of the rotating block 7 is rotatably connected to multiple connecting rods 8, and each connecting rod 8 is rotatably connected to a limit block 9 on one side. The limit block 9 is slidably connected inside the slide groove 6, and the side wall of the limit block 9 is fixedly connected to a clamping plate 10. The support mechanism is located behind the fixed mechanism and is used to support the fixed mechanism. The support mechanism includes a limit frame 11, the side wall of the limit frame 11 is fixedly connected to the upper surface of the placement plate 2, the side wall of the limit frame 11 is slidably connected to a slider 12, the upper surface of the slider 12 is fixedly connected to a bracket 13, the side wall of the bracket 13 is fixedly connected to the side wall of the fixed plate 3, and one side of the bracket 13 is located inside the electric slide rail 14.

[0035] During the grinding and polishing process of the workpiece using this equipment, the workpiece to be processed is first placed in the middle of the clamping plate 10. Then, the motor 4 is started, driving the rotating block 7 to rotate. As the rotating block 7 rotates, the connecting rod 8 also begins to move accordingly. During this process, one end of the connecting rod 8 rotates on the surface of the rotating block 7 and deflects along with the rotation of the rotating block 7. At the same time, the other end of the connecting rod 8 rotates on the surface of the limiting block 9, and pulls the limiting block 9 during the rotation, causing it to slide along the center direction inside the slide groove 6. During the sliding process, the limiting block 9 applies pressure to the workpiece through the clamping plate 10, thereby clamping and fixing the workpiece. After the workpiece is successfully fixed, the electric slide rail 14 is started, driving the bracket 13 to move on the slider 12. As the bracket 13 moves, the fixing mechanism also moves accordingly, causing the workpiece to gradually move towards the processing mechanism, ultimately achieving the processing of the workpiece.

[0036] Reference Figures 1-3The processing mechanism is used for grinding workpieces. The processing mechanism includes a fixed frame 15, a water tank 16 inside the fixed frame 15 for storing liquid, a water pump 17 on the top of the water tank 16, and a water outlet pipe 18 fixedly connected to the output end of the water pump 17. The water outlet pipe 18 passes through the fixed frame 15 and extends to its top. A drip head 19 is provided at one end of the water outlet pipe 18. A motor 20 is fixedly connected inside the fixed frame 15. A processing plate 21 is fixedly connected to the output end of the motor 20. A recycling box 22 is slidably connected inside the placement plate 2. A filter plate 23 is slidably connected inside the recycling box 22. The recycling box 22 is located at the bottom of the processing plate 21.

[0037] Motor 20 is started, which in turn drives the processing disc 21 to rotate. During the rotation of the processing disc 21, the workpiece is ground and polished. The workpiece can be processed by attaching a grinding plate or polishing plate to the processing disc 21. At the same time, water pump 17 is started, and water is drawn from water tank 16. The drawn water is transported upward through water outlet pipe 18 and then dripped out by drip head 19. The water droplets dripping from drip head 19 can effectively prevent damage to the workpiece due to overheating during the grinding process. The dripping liquid not only has a cooling effect, but also allows the dust particles to slide down into the collection box 22 for collection. After the entire grinding and polishing process is completed, the collection box 22 can be pulled out from the placement plate 2 for further treatment of the collected wastewater.

[0038] Working principle: When using this equipment, first place the workpiece between the clamping plates 10, then start the motor 4 to drive the rotating block 7 to rotate, which in turn drives the connecting rod 8 to move. One side of the connecting rod 8 rotates on the rotating block 7 and deflects along with it. At the same time, the other side of the connecting rod 8 rotates on the limiting block 9 and pulls the limiting block 9 to move. The limiting block 9 then slides inward inside the slide groove 6, clamping and fixing the workpiece through the clamping plates 10. After the workpiece is fixed, the electric slide rail 14 drives the bracket 13 to move on the slider 12. The movement of the workpiece, in turn, causes the fixed mechanism to move, gradually moving the workpiece toward the processing mechanism. At this time, the motor 20 is started to drive the processing disc 21 to rotate, and the workpiece is polished by the processing disc 21. At the same time, the water pump 17 is started to draw water from the water tank 16 and transport it upward through the water outlet pipe 18. The water is dripped out by the drip head 19 to avoid overheating and damage to the workpiece during polishing. The dripping liquid and dust particles will slide into the inside of the recycling box 22 for collection. After the work is completed, the recycling box 22 is pulled out from the inside of the placement plate 2 to treat the collected wastewater.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
