[0025] Specifically, when the motor 4 is started, it drives the screw rod 5 to rotate rapidly and stably; the rotation of the screw rod 5 further drives the rack block 6 to slide on the inner wall of the fixed box 3; the rack block 6 drives the gear 8 to rotate synchronously during the movement; the rotation of the gear 8 is further transmitted to the rotating shaft 7 connected thereto, so that the rotating shaft 7 drives the connecting frame 9 of the outer wall to flip; this flipping effect enables the connecting frame 9 to easily adjust the angle, thereby realizing the grinding operation on the other side of the workpiece; after the workpiece is polished, by turning the knob 1 402, the screw rod 1401 can drive the clamping block 13 to detach from the workpiece; in this process, the telescopic rod 12 plays a key limiting role in the movement of the clamping block 13, ensuring that the clamping block 13 can be smoothly and accurately detached from the workpiece; in addition, the device uses a hydraulic column 10 as an auxiliary when fixing the workpiece; when the workpiece needs to be fixed, the hydraulic column 10 will push the clamping block 13 to cooperate with the clamping block 11 to clamp the workpiece together; this design not only improves the stability of clamping, but also makes the fixation of the workpiece more convenient and quick.

[0026] Reference Figure 1 , Figure 2 and Figure 3The upper surface of the bracket 2 is fixedly connected to a motor 2 15, and the output end of the motor 2 15 is fixedly connected to a screw rod 3 16; the outer wall of the screw rod 3 16 is threadedly connected to a sliding frame 17, and the sliding frame 17 is slidably connected to the inside of the bracket 2, and the lower surface of the sliding frame 17 is fixedly connected to an electric slide rail 18, and the outer wall of the electric slide rail 18 is slidably connected to an electric push rod 19, and the output end of the electric push rod 19 is fixedly connected to a stabilizing frame; the lower surface of the stabilizing frame is rotatably connected to an articulated seat 20, and the outer wall of the articulated seat 20 is fixedly connected A grinding mechanism 21; a second electric push rod 22 is rotatably connected to the lower surface of the stabilizing frame, and the output end of the second electric push rod 22 is rotatably connected to one side of the outer wall of the grinding mechanism 21; a water tank 23 is fixedly connected to the inner wall of the workbench 1, and a filter box 24 is slidably connected inside the water tank 23; a circulating pump 25 is fixedly connected to the inner wall of the workbench 1, the input end of the circulating pump 25 is fixedly connected to the inside of the water tank 23, and the output end of the circulating pump 25 is fixedly connected to a water spray pipe 26, and the outer wall of the water spray pipe 26 is fixedly connected to one side of the outer wall of the bracket 2;

[0027] Specifically, by starting the second motor 15, the screw rod 3 16 can be driven to rotate; during the rotation of the screw rod 3 16, the sliding frame 17 is limited to slide inside the bracket 2; this limited sliding design ensures the stability and accuracy of the sliding frame 17 during the movement; as the sliding frame 17 moves, it will drive the electric slide rail 18 to make corresponding adjustments; when the sliding frame 17 and the electric slide rail 18 are adjusted to the appropriate position, by starting the cooperation of the electric slide rail 18 and the electric push rod 1 19, the grinding mechanism 21 can be easily brought close to the workpiece; the grinding mechanism 21 usually adopts a high-speed rotating grinding head or grinding wheel, which can quickly and effectively remove the burrs on the surface of the workpiece; in the process of removing the burrs, by starting the electric push rod 2 22, the hinged seat 20 above the grinding mechanism 21 can be driven to rotate; this The rotating action enables the grinding mechanism 21 to flexibly adapt to the shape and size of the workpiece, so as to remove the burrs on the side of the workpiece; at the same time, by starting the circulation pump 25, the clean water inside the water tank 23 can be transmitted to the workpiece through the water spray pipe 26 to cool it down; this can not only effectively prevent the heat generated during the grinding process from damaging the workpiece, but also improve the grinding efficiency and quality; in the process of removing burrs, a large amount of solid-liquid mixture will be produced; in order to effectively handle these mixtures, the device is also designed with a collecting hopper and a filter box 24; the collecting hopper is located above the water tank 23, and can collect debris and liquid falling from the workpiece; the filter box 24 is located below the collecting hopper, and the debris can be filtered and collected through the filter net or filter element inside it, and the liquid flows into the water tank 23 for recycling.

[0028] Working principle: when it is needed, the screw rod 3 16 is driven to rotate by starting the motor 2 15, and the screw rod 3 16 drives the sliding frame 17 to slide within the bracket 2 through the screw rod 3 16, and the sliding frame 17 drives the electric slide rail 18 to adjust the angle to achieve angle adjustment. At this time, the electric slide rail 18 and the electric push rod 1 19 are started to cooperate, so as to facilitate the grinding mechanism 21 to approach the workpiece and realize the burr removal operation. At this time, the electric push rod 22 is started again, and the articulated seat 20 above the grinding mechanism 21 is driven by the electric push rod 22 to rotate, so as to achieve the effect of removing the burrs on the side of the workpiece. While removing the burrs, the circulating pump 25 is started, and the clean water inside the water tank 23 is transmitted to the workpiece through the water spray pipe 26 by the circulating pump 25 for cooling treatment. At this time, the solid-liquid mixture is collected by the collecting bucket on the water tank 23, the debris is collected by the filter box 24, and the liquid is collected inside the water tank 23, so as to achieve the effect of recycling water resources.

[0029] Secondly, after the burrs on one side of the workpiece are removed, the motor 4 is started to drive the screw rod 5 to rotate, and the screw rod 5 drives the rack block 6 to slide on the inner wall of the fixed box 3. The rack block 6 and the gear 8 are meshed and rotated, and the connecting frame 9 on the outer wall of the rotating shaft 7 is turned by the gear 8, so as to facilitate the grinding of the other side. After the workpiece is ground, the knob 1402 is turned to make the screw rod 2 1401 drive the clamping block 2 13 to separate from the workpiece, and the telescopic rod 12 limits the movement of the clamping block 2 13. However, when fixing the workpiece, the hydraulic column 10 can assist the clamping block 2 13 to push the clamping block 11 to clamp the workpiece.
