[Prior Art] According to the rapid development of modern industry, its progress can be described as a thousand miles, the industry can be so developed, the heavy industry is very important, but the medium and small tools industry is indispensable. The so-called "workers must do their best. "The tool", φ wants to make the work more renewed, excellent medium, small and secret equipment is also very important, the domestic small and medium-sized tool industry development has reached a point of considerable washing, No matter whether it is the product surface or the 疋 叩 i i 自 自 自 自 i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i Upgrade. - If the industry wants to add n to the secret, such as the needle map, the structure diagram does not need to use drilling tools, tapping machines and other drilling tools, and its reading may be 峨, steel , ϋ or tc mechanical parts, etc., the size of the area is variable, and the difference is very large, it is difficult to simply be fixed by the vise _ or gossip gripper on the work plate of the drill, so that the staff will feel silver If you want to use a small part, you need to use the sweetness of the tiger first, or you should be sensitive to the health of the worker, and increase the health of the machine. Therefore, the right use of the magnetic work plate to adsorb the fixed workpiece, can achieve twice the result with half the effort; the work plate itself is mixed with the drilling operation and the rotation is adjusted according to the situation, _ in the control processing, do not sigh, but magnetic The working plate is also equipped with a coil winding area for generating a magnetic field. Therefore, it is necessary to have a matching design for the eight suspicious transition adjustments. Otherwise, in the case where the working disk rotates, it is easy to cause one way and the electric w cannot be turned on. So that no magnetic field can be generated and the miscellaneous work disk is lost. Benefit; therefore, the 5 M336098 work disk must have a part and the drill nj set the grain to form a magnetic field, while the other part needs to be rotatable to adjust the work and work; 'More, a magnetic The working plate can be used with drilling tools such as drilling machines and tapping machines of different specifications, and the force of the disk is used for the turning of the disk. Therefore, it is difficult to design the disk, and the stability between the wire paths must be considered. "The strength of the magnetic field, the line problem of the woman's work, and the adaptability of the drill can be matched. From the above, it is not easy to design a magnetic work disk;
