[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and flat surface.

At this time, the multiple shielding cloths located around the two electric telescopic rods can be surrounded in a rectangular shape, waiting for the subsequent polishing of the circular metal plate; Step 2: After the circular metal plates to be polished are stacked and placed directly below the two fixed rods, a magnetic force is generated by controlling the upper electromagnet to be energized, and the two first sliders are used to drive the first motor and the electric telescopic rod to move together along the first slide groove to above the stacked multiple circular metal plates, and the telescopic end of the upper electric telescopic rod is extended downward to drive the electromagnet to magnetically fix the top of the circular metal plates, and one of the moving blocks is controlled to drive the second motor and the lower electric telescopic rod to move in a direction close to the upper electric telescopic rod.

[0015] The beneficial effects of the present invention are: 1. In the present invention, by means of a first polishing mechanism arranged inside the frame, after polishing the top of the circular metal plate, the bottom of the circular metal plate can be polished, so that the device can automatically polish both the upper and lower surfaces of the circular metal plate, thereby improving the polishing efficiency of the circular metal plate, and further improving the output of the polishing of multiple circular metal plates.

[0016] 2. In the present invention, after the circular metal plates to be polished are stacked and placed directly below the two fixed rods, the upper electromagnet is controlled to be energized to generate magnetic force, and the two first sliders are used to drive the first motor and the electric telescopic rod to move along the first slide groove to the top of the stacked multiple circular metal plates, and the telescopic end of the upper electric telescopic rod is extended downward to drive the electromagnet to magnetically fix the top of the circular metal plates, and then one of the moving blocks is controlled to drive the second motor and the lower electric telescopic rod to move in the direction close to the upper electric telescopic rod, until the second motor moves to a position on the same straight line as the upper electric telescopic rod, at which time the telescopic end of the upper electric telescopic rod can be controlled to extend downward to place the magnetically attracted circular metal plate on the top of the lower circular plate, and the multiple third rotating frames below are controlled to move in a direction close to each other, so as to push the four sides of the circular metal plate placed on the top of the lower circular plate, and the circular metal plate can be accurately placed on the top of the lower circular plate, and the electromagnet on the top of the lower circular plate is controlled to be energized to magnetically fix the circular metal plate, so as to achieve the effect of accurately limiting and fixing the circular metal plate to be polished.

[0018] 4. In the present invention, since the multiple third rotating racks above are in a downward vertical state during the polishing process of the circular metal plate, and the multiple shielding cloths are in an unfolded state, they can shield and protect the debris and other impurities generated during the polishing process, and prevent them from splashing outward from the top of the circular metal plate as the multiple first polishing pads rotate at high speed. This is convenient for improving the cleanliness of the working area during the polishing process, and can also have a protective effect on the surrounding staff. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the circular metal plate can be accurately placed on the top of the circular plate 12 below, and the electromagnet 18 on the top of the circular plate 12 below can be controlled to be energized and magnetically fixed to the circular metal plate, so as to achieve the effect of accurately limiting and fixing the circular metal plate to be polished.

[0035] If the circular plate to be polished cannot be magnetically attracted by the electromagnet 18, the electric telescopic rod 8 above can be moved to the top of the stacked circular plates, as shown in FIG. Figure 2 As shown, when the telescopic end of the electric telescopic rod 8 is controlled to extend downward until it contacts the top of the circular plate below, the multiple third rotating frames 11 above are directly controlled to move in a direction of approaching each other, so that the multiple third rotating frames 11 at this time can be used as auxiliary clamps to directly clamp and drive the circular plate that cannot be magnetically attracted all around, and then the electric telescopic rod 8 above is moved and reset to control the multiple third rotating frames 11 to release the clamping and fixation of the circular plate, so that the circular plate can be directly placed between the multiple third rotating frames 11 below, and the circular plate can be clamped and fixed with the help of the multiple third rotating frames 11 below, thereby ensuring that the circular plate that cannot be magnetically attracted can also have the effect of automatic loading.

[0036] After the position of the circular metal plate to be polished is fixed, the multiple first rotating frames 9 above can be controlled to drive the multiple second rotating frames 10 to rotate downward together to an inclined state, and at the same time, the multiple second rotating frames 10 can be controlled to adaptively rotate upward to a horizontal state inside the moving seat 22, and then the multiple third rotating frames 11 can be controlled to rotate inside the corresponding second rotating frames 10 to a state perpendicular to the second rotating frames 10, so that the first polishing pads 23 arranged at the bottom of the multiple second rotating frames 10 are located below the circular plate 12, and then the multiple second rotating frames 10 below are controlled to drive the third rotating frames 11 to rotate downward together to an inclined state. Figure 3 In the state shown, the circular metal plate to be polished is located above the lower circular plate 12 and is fixed by the magnetic attraction of the electromagnet 18. The telescopic end of the upper electric telescopic rod 8 is controlled to extend downward, driving the first polishing pads 23 at the bottom of the multiple second rotating frames 10 to contact the top of the circular metal plate. The first motor 6 is controlled to drive the upper electric telescopic rod 8 to rotate, while driving the multiple first polishing pads 23 below to rotate and rub against the top of the circular metal plate, thereby achieving the effect of automatically polishing the top of the circular metal plate.

[0037] While polishing the top of the circular metal plate, since the polishing range of the multiple first polishing pads 23 on the top of the circular metal plate is limited, the two moving blocks 14 can be controlled to drive the second motor 7 and the electric telescopic rod 8 below and other components to move back and forth inside the rectangular groove 4, thereby driving the movement trajectory of the magnetically attracted circular metal plate to be limited to the space enclosed by the multiple third rotating frames 11 above that rotate downward and are in a vertical state, so that the multiple first polishing pads 23 above can perform a comprehensive polishing process on the top of the circular metal plate to avoid the generation of polishing dead corners.

[0038] Since the multiple third rotating frames 11 above are in a downward vertical state during the polishing of the circular metal plate, and the multiple shielding cloths 34 are in an unfolded state, they can shield and protect the debris and other impurities generated in the polishing process, avoiding the situation where they are splashed out from the top of the circular metal plate as the multiple first polishing pads 23 rotate at high speed, which is convenient for improving the cleanliness of the working area during the polishing process and can also have a protective effect on the surrounding staff.

[0039] After the top of the circular metal plate is polished, the bottom of the circular metal plate needs to be polished. At this time, the second rotating racks 10 and the third rotating racks 11 above can be controlled to rotate in a Figure 3The state shown is shown, and then the multiple second rotating frames 10 and the third rotating frames 11 below are controlled to rotate upward to the original state, and the electromagnet 18 below is controlled to release the magnetic fixation of the circular metal plate, and the upper electric telescopic rod 8 drives the upper electromagnet 18 to magnetically fix the polished top of the circular metal plate, and the multiple first rotating frames 9 below drive the second rotating frames 10 and the third rotating frames 11 to rotate downward together, and after controlling the multiple second rotating frames 10 to adaptively rotate downward to a horizontal state, ensure that the multiple third rotating frames 11 are adaptively rotated to a state perpendicular to the second rotating frames 10, At this time, the telescopic end of the electric telescopic rod 8 below can be controlled to extend upward, driving the first polishing pads 23 on the top of the multiple second rotating frames 10 below to abut against the bottom of the circular metal plate, and the second motor 7 is used to drive the multiple first polishing pads 23 below to polish the bottom of the circular metal plate, and during the polishing process, the second motor 7 is controlled to move back and forth in a small range inside the rectangular groove 4, so as to facilitate the comprehensive polishing of the bottom of the circular metal plate, so that the device can automatically polish the upper and lower surfaces of the circular metal plate, thereby improving the polishing efficiency of the circular metal plate.

[0040] When polishing a non-metallic material or a metal circular plate that cannot be fixed by the magnetic attraction of the electromagnet 18, Figure 2 As shown, when the circular plates are clamped and fixed by means of the multiple third rotating frames 11 below, the multiple second rotating frames 10 are controlled to drive the multiple third rotating frames 11 to rotate downward together, and then the multiple third rotating frames 11 are controlled to rotate upward to be applicable to a vertical state, so that the top ends of the multiple third rotating frames 11 clamp and fix the four sides of the circular plates, and ensure that the top ends of the multiple third rotating frames 11 are flush with the top of the circular plates, so that the first polishing pads 23 at the bottom of the multiple second rotating frames 10 above can polish the top of the circular plates. When polishing the bottom of the circular plates, the multiple third rotating frames 11 above can clamp and fix the circular plates, and ensure that the bottom ends of the multiple third rotating frames 11 above are flush with the bottom ends of the circular plates, so that the first polishing pads 23 at the tops of the multiple second rotating frames 10 below can polish the bottom of the circular plates, so as to realize the double-sided polishing of non-metallic materials or metal circular plates that cannot be fixed by magnetic attraction of the electromagnet 18, thereby further improving the applicability of the equipment in actual use.

[0041] After polishing the upper and lower surfaces of the circular metal plate, the electromagnet 18 below can be controlled to continue to magnetically fix the circular metal plate, and then the multiple first rotating frames 9, the second rotating frames 10 and the third rotating frames 11 above can be controlled to rotate and reset to their original states. Figure 2 The state shown in the figure is obtained, at this time, the first rotating frame 9, the second rotating frame 10 and the third rotating frame 11 below are Figure 3In the state shown, the multiple double-headed screws 37 above can be controlled to rotate, driving the two shaping blocks 26 to move in the direction of moving away from each other to the maximum distance, so that the two second polishing pads 31 set on the side close to the multiple third rotating frames 11 are exposed, and the telescopic end of the electric telescopic rod 8 above is controlled to extend downward so that the circular metal plate is located between the multiple third rotating frames 11, and then the multiple driving screws 28 above are controlled to rotate together, driving the multiple third rotating frames 11 to move in the direction of approaching, and driving the two second polishing pads 31 set on the side close to the multiple third rotating frames 11 to abut against the circular outer wall of the circular metal plate. As the first motor 6 drives the multiple third rotating frames 11 above to rotate synchronously, the multiple second polishing pads 31 are driven to rotate and rub against the circular outer wall of the circular metal plate, and the circular outer wall of the circular metal plate is polished, thereby achieving comprehensive automatic polishing of the surface of the circular metal plate, further improving the efficiency of polishing the surface of the circular metal plate, and facilitating improving the applicability of the equipment during actual use.

[0042] If the polished circular metal plate needs to be chamfered at the edge, the multiple driving screws 28 can be controlled to reverse together, driving the two corresponding shaping blocks 26 to move in the direction of approaching each other, and driving the arc inner walls set on the adjacent side of the two corresponding shaping blocks 26 to abut against the edge position of the circular metal plate. As the first motor 6 continues to drive the multiple third rotating frames 11 to rotate, the multiple shaping blocks 26 are driven to automatically chamfer the edge of the circular metal plate, so that there is no need to use special processing equipment to process the edge of the circular metal plate in the future, thereby further improving the applicability of the equipment; because the second sliding block 32 is installed inside the second groove 27 through the cooperation of the screw rod 35 and the nut, the second sliding block 32 and the second groove 27 are detachably installed. When processing the edges of circular metal plates of different diameters, the second sliding block 32 can be removed from the inside of the second groove 27, and the two shaping blocks 26 adapted thereto can be replaced, so that different shaping blocks 26 can be used to process the edges of circular metal plates of different diameters.

[0043] If the surface of the rectangular plate needs to be polished, the first rotating frame 9, the second rotating frame 10 and the third rotating frame 11 inside the frame body 1 can be controlled to rotate and adjust the shape. Figure 3In the state shown, the multiple movable seats 22 are controlled to slide and be stored inside the corresponding first rotating frame 9, and then the two polishing wheels preset outside are respectively mounted on the surfaces of the multiple second rotating frames 10 above and below, and then the multiple movable seats 22 are controlled to slide and extend from the inside of the corresponding first rotating frame 9, driving the first polishing pads 23 set on the outer walls of one side of the multiple second rotating frames 10 to closely abut against the inner wall of the polishing wheel, so that the multiple first polishing mechanisms can be used as mounting mechanisms for the two polishing wheels respectively at this time. After the two polishing wheels are respectively mounted on the surfaces of the multiple second rotating frames 10, the telescopic ends of the two electric telescopic rods 8 are controlled to extend downward and upward respectively, driving the positions of the two polishing wheels to be adjusted to the state on the same straight line, and finally the second motor 7 below is controlled to move in the direction close to the first motor 6 inside the rectangular groove 4 until the spacing between the two polishing wheels is adapted to the thickness of the plate to be polished, and then the first motor 6 and the second motor 7 are controlled to start together, driving the two polishing wheels to turn in opposite directions, so that the plate can be placed between the two polishing wheels for double-sided polishing, so that the equipment can also automatically perform double-sided polishing on rectangular plates.
