[0025] In this utility model, the working disk 5 is designed as a cavity structure with an installation cavity 6.

When the electromagnet 7 is powered on, it will generate a strong magnetic adsorption function to hold the workpiece, which is particularly suitable for ferromagnetic materials. It eliminates the cumbersome steps in the traditional film pasting process, such as adhesive film pasting and vacuum adsorption, greatly simplifying the clamping process; the electromagnet 7 workpiece disk can also provide more uniform and stable suction force, reducing the risk of displacement or deformation of the workpiece during processing, thus ensuring the processing accuracy, not only improving the work efficiency but also improving the processing quality, providing strong support for high-efficiency and precision manufacturing; the electromagnet 7 working disk 5 only consumes electric energy during operation, without the need for an additional power source, reducing ineffective actions and time waste during the process and reducing energy consumption. Through the arranged ceramic insulating backing plate 4, it effectively isolates current interference. Ceramic has high-temperature resistance and insulation properties, protecting the DD motor 3 from overheating and electrical short circuits, and the wear resistance and corrosion resistance of ceramic provide long-term stability for the equipment.

[0026] Referring to Figure 4 and 5 As shown, in this embodiment, a number of mounting holes 53 and mating holes 41 are respectively annularly and evenly distributed at the edges of the working disk 5 and the insulating backing plate 4. The mounting holes 53 are fixedly connected to the insulating backing plate 4 by screws. A magnet fixing hole 51 matching the electromagnet 7 is arranged through the bottom of the installation cavity 6, and the electromagnet 7 in the installation cavity 6 is fixedly installed through the magnet fixing hole 51 with screws. Through the arranged mounting holes 53 and magnet fixing holes 51, it is possible to conveniently and quickly install and fix the working disk 5 and the electromagnet 7 for subsequent daily maintenance of the working disk 5 and the electromagnet 7.

The light-shielding piece 117 functions to trigger the photoelectric switch 112 when the sliding seat 115 slides to both ends of the slide rail 114. By arranging the photoelectric switch 112 and the rotary limit block 111, when the DD motor 3 drives the insulating pad and the working disk 5 to rotate to the maximum stroke in two directions, the sliding seat 115 can drive the light-shielding piece 117 to trigger the photoelectric switch 112 in time, so as to stably transmit the rotation angle of the working disk 5 at the maximum stroke at this time, which is beneficial to accurately controlling the rotation of the working disk 5.

[0030] Referring to Figure 6 As shown in the figure, in this embodiment, a limit post 118 is fixedly arranged in the middle of the sliding seat 115. A buffer spring 119 is hooked between both ends of the support frame 113 and the limit post 118.
