Therefore, the surface of the workpiece M and the surrounding sides can be reduced. For processing. M258824 Please refer to the eighth picture: This is a schematic diagram of the use state of this creation suitable for drilling of workpieces. The plate surface 20 is a consumable and can be used for drilling holes or milling slots. As long as the workpiece M is adsorbed on the plate surface 20, it can solve the problem that conventional magnetic disks or electromagnetic disks cannot be drilled. The disadvantages of using holes. Please refer to the ninth picture: this creation is suitable for the use of multiple small workpieces at a time. As shown in the figure, five connecting pieces 6 8 are used to combine two rows of ten magnetic seats with magnetic attraction (of course, each of the magnetic seats must also be fixed to the work machine's work table 8 0 by a fixture 70. Positioner on the T-shaped chute 8 1), each magnetic seat at least on the two adjacent sides of the wear-resistant plate 3 2 side locking two positioning plate 9 0, each magnetic seat can provide a small workpiece M By positioning by suction, ten small workpieces M can be processed at the same time. Please refer to the tenth picture: this is a schematic diagram of the plane combination of this creation with a straight fixture. The magnetic base provided in this creation can be set on the straight fixture 71 by using a fixture. In addition to being suitable for general horizontal processing (as shown in Figures 11 and 12), it can also be used for standing. Type processing (as shown in Figures 13 and 14). Based on the above-mentioned Chen Zhiben's creation, it is to provide a switch-type permanent magnetic worktable fixture system. After the author's actual production and repeated operation test and reading, it is confirmed that $ can indeed achieve the detailed functional benefits of the work, and at the same time For the "first creation" that has not yet been heard in the market, it has "industrial use value", and it certainly meets the essentials of the establishment of new patents "practical" and "progressiveness." M258824 Filed a new patent application. [Schematic description] The first picture is a three-dimensional combination diagram of this creation. The second picture is a three-dimensional exploded view of this creation. The third picture: is a sectional view of the front view of this creation. The fourth picture: is a schematic sectional view of this creation from the top. Fifth picture: It is a schematic diagram of the magnetic absorption state of this creation. Figure 6: This is a schematic diagram of the use of demagnetization in this creation. Figure 7: This work is suitable for large-scale workpieces. (Schematic diagram of official use. Figure 8: This work is suitable for use in drilling of workpieces. Figure 9: This work is suitable for more than one time. Schematic diagram of the use state of a small workpiece.
