[0024] In this example, the horizontal bars 2 and magnetic isolation plates 3 are distributed at equal intervals, and the front cross-sectional shape of the magnetic isolation plates 3 is a "concave" shape. The above structural design enables the horizontal bars 2 and magnetic isolation plates 3 to evenly distribute the magnetic forces of different polarities formed by the pole core 6 and the shell 9 on the panel.

[0025] The positioning bolt 11 is slidably connected to the track groove 10. The side view shapes of the positioning bolt 11 and the track groove 10 are both "T"-shaped. The above structural design ensures that the positioning bolt 11 will not be vertically separated from the track groove 10, and the positioning bolt 11 can be stably slid and adjusted along the track groove 10.

[0026] The positioning bolts 11 are symmetrically distributed about the center of the mounting plate 13 , and the mounting plate 13 is symmetrically distributed about the center of the housing 9 . The above structural design enables the mounting plate 13 to be stably installed, and the housing 9 and the pole block 1 as a whole can be stably installed.

[0027] The front view shape of the mounting plate 13 is "T"-shaped, and the width of the mounting plate 13 is greater than 1 / 8 of the width of the housing 9. The above structural design enables the mounting plate 13 to stably position the housing 9 and the pole block 1.

The length of the vertical mounting windows 14 is greater than 1 / 3 of the length of the vertical portion of the mounting plate 13 . The above structural design enables the connecting tool to pass through the vertical mounting windows 14 and connect to the vertical mounting surface.

[0029] A first bottom mounting groove 15 is formed on one side of the bottom end of the mounting plate 13, and a second bottom mounting groove 16 is formed on the other side of the bottom end of the mounting plate 13. The above structural design enables the connecting tool to connect the mounting plate 13 to the horizontal mounting surface.

[0030] The center of the first bottom mounting groove 15 and the center of the second bottom mounting groove 16 are on the same vertical plane, and the top view shapes of the first bottom mounting groove 15 and the second bottom mounting groove 16 are both "U"-shaped. The above structural design enables expansion bolts and other connecting tools to be easily installed through the first bottom mounting groove 15 and the second bottom mounting groove 16.

[0031] Working principle: The pole pieces 1, horizontal bars 2 and magnetic isolation sheets 3 are inlaid according to a fixed pole pitch to form a panel. Its structure is the same as that of an ordinary electromagnetic chuck panel. The magnetic forces of different polarities formed by the pole core 6 and the shell 9 are evenly distributed on the panel, so that the pole pieces 1 and horizontal bars 2 on both sides of the magnetic isolation sheet 3 produce different magnetic properties, thereby generating a holding force on the magnetic conductor close to or in contact with the panel.

[0032] During installation, according to the position of the preset holes on the mounting surface of the grinder, push the positioning bolt 11 to slide and adjust along the track groove 10 until the position of the mounting plate 13 is appropriate, rotate the positioning nut 12 to squeeze the shell 9, and fix the position of the mounting plate 13. The positioning bolt 11, positioning nut 12 and mounting plate 13 are made of non-conductive non-metallic materials, such as engineering plastics, which will not interfere with the normal operation of the panel-type electric permanent magnetic suction cup. Then, according to whether the mounting surface of the grinder is a vertical surface or a horizontal surface, select the vertical mounting window 14 or the first bottom mounting groove 15 or the second bottom mounting groove 16, use expansion bolts or other connecting tools to pass through the vertical mounting window 14 or the first bottom mounting groove 15 or the second bottom mounting groove 16, and connect and fix the mounting plate 13 to the preset holes on the mounting surface of the grinder. The panel-type electric permanent magnetic suction cup can be used stably as a whole. This is the working principle of the panel-type electric permanent magnetic suction cup.
