[0029] The driving structure 1 drives the container structure 2 so that the workpiece 3 in the container structure 2 is polished by the abrasive driven by the rotation of the magnet. After the single-side polishing is completed, it is flipped by the clamping structure 4 to polish the other side of the workpiece 3.

[0030] The driving structure 1 includes a base plate 101, a mounting box 102, a support wheel 103, a driving motor 104, a driving rod 105, and a magnetic disk 106.

[0031] The magnetic disk 106 can provide magnetic force to the polishing container 201, and the driving motor 104 drives the polishing container 201 through the driving rod 105. At the same time, the polishing container 201 rotates on the supporting wheel 103, which reduces friction and plays a certain supporting role, thereby improving the stability of transmission.

[0032] The container structure 2 includes a polishing container 201 , a polishing cavity 202 , and a connecting hole 203 . The polishing container 201 contains the polishing cavity 202 . The bottom of the polishing container 201 is provided with a connecting hole 203 , which is plugged into the driving rod 105 of the driving motor 104 .

[0033] Before the polishing container 201 performs magnetic polishing on the workpiece 3, it is necessary to add polishing abrasives, generally stainless steel needles, into the container, and then add a certain solution. After the workpiece 3 is introduced into the polishing chamber 202 through the clamping structure 4, the container is rotated by driving the connecting hole 203 through the driving rod 105, so that the stainless steel needles inside it generate magnetic movement, and one side of the workpiece 3 is polished. After one side is completed, it is flipped over by the clamping structure 4.

[0034] The clamping structure 4 includes a support frame 401, a connecting block 402, an electric telescopic rod 403, a door frame 404, a first motor 405, a rotating rod 406, a rotating shaft 407, a second motor 408, a third motor 409, a connecting arm 410, a suction nozzle 411, and a quick-insert interface 412. The top center of the support frame 401 is fixedly connected with a connecting block 402, the support frame 401 is connected to the lifting arm through the connecting block 402, the support arm of the support frame 401 is connected with the electric telescopic rod 403, the driving end of the electric telescopic rod 403 is connected with the door frame 404, and the bottom support arm of the door frame 404 A first motor 405 is connected, a driving end of the first motor 405 is connected to a rotating rod 406, both side ends of the rotating rod 406 are connected to rotating shafts 407, the rotating shafts 407 are connected to the driving end of a second motor 408, the second motor 408 is fixedly connected to the rotating rod 406, an end of the rotating shaft 407 is fixedly connected to a third motor 409, a driving end of the third motor 409 is fixedly connected to a three-stage telescopic rod, a rod end of the three-stage telescopic rod is fixedly connected to a connecting arm 410, the other side end of the connecting arm 410 is connected to a suction nozzle 411, and one end of the suction nozzle 411 is provided with a quick-plug interface 412.

[0035] When flipping is required, the door frame 404 and the workpiece 3 adsorbed by the suction nozzle 411 are raised by the electric telescopic rod 403 so that it has a certain flipping space, and then the first motor 405 drives the rotating rod 406 to rotate, and then one of the groups of suction nozzles 411 at the diagonal positions on both sides of the door frame 404 first cuts off the vacuum adsorption state, and then the third motor 409 drives it to rotate a certain angle, and the second motor 408 drives the rotating shaft 407 to flip the third motor 409 and the suction nozzle 411 rotated at a certain angle, so that the polished side of the workpiece 3 is flipped, and then it is reset by the motor to be adsorbed on the polished side, and then the above steps are repeated on the other group of suction nozzles 411 to complete the position switching of the clamping suction nozzle 411 to prevent the unpolished surface from having clamping points that cannot be polished, thereby improving the overall polishing effect of the workpiece 3.

[0036] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0037] In summary, with the aid of the above-mentioned technical scheme of the utility model, the container structure 2 is driven by the driving structure 1, so that the workpiece 3 in the container structure 2 is polished by the abrasive driven by the rotation of the magnet. After the single-sided polishing is completed, it is turned over by the clamping structure 4 to polish the other side of the workpiece 3. The magnetic disk 106 can provide magnetic force to the polishing container 201. The driving motor 104 drives the polishing container 201 through the driving rod 105. At the same time, the polishing container 201 rotates on the supporting wheel 103, which reduces the friction and plays a certain supporting role, thereby improving the stability of the transmission. Before the polishing container 201 performs magnetic polishing on the workpiece 3, it is necessary to add polishing abrasive, generally a stainless steel needle body, into the container, and then add a certain solution. After the workpiece 3 is introduced into the polishing cavity 202 through the clamping structure 4, the container is rotated by driving the connecting hole 203 through the driving rod 105, so that the stainless steel needle body inside it generates magnetic movement. The workpiece 3 is polished by the clamping structure 4 after one side is completed. When it is necessary to flip, the door frame 404 and the workpiece 3 adsorbed by the suction nozzle 411 are raised by the electric telescopic rod 403, so that it has a certain flipping space. Then the first motor 405 drives the rotating rod 406 to rotate, and then one of the groups of suction nozzles 411 at the diagonal positions on both sides of the door frame 404 first cuts off the vacuum adsorption state, and then the third motor 409 drives it to rotate a certain angle, and the second motor 408 drives the rotating shaft 407 to flip the third motor 409 and the suction nozzle 411 rotated at a certain angle, so that the polished side of the workpiece 3 is flipped, and then it is reset by the motor to be adsorbed on the polished side, and then the above steps are repeated on the other group of suction nozzles 411 to complete the position switching of the clamping nozzle 411 to prevent the unpolished surface from having clamping points that cannot be polished, thereby improving the overall polishing effect of the workpiece 3.
