Abstract
The utility model discloses a panel-type permanent electromagnetic chunk, which is extensively applicable to hold work piece in various sizes. The main component of the utility model is a permanent electromagnetic chunk consisting of a permanent magnetic steel part, a reversible magnetic steel part, a coil and a pole piece. The utility model is characterized in a cover plate covered on upper surface of the permanent electromagnetic chunk. Meanwhile, the cover plate is made up of piece used to insulate magnetism and a crossband, and then filling materials insulating magnetism are placed according to magnetic space needed.
Description
(1) technical field
The utility model relates to fixture for grinding machine, is specially a kind of panel type electric permanent-magnet suction disc.
(2) background technology
Electric permanent-magnet suction disc is a kind of newer technology, and it is safe with respect to magnechuck commonly used, suction is powerful, machining accuracy is high and energy-conserving and environment-protective.What but this electric permanent-magnet suction disc adopted is modular structure, and module is generally all bigger, is unsuitable for the less workpiece of sticking; See Fig. 1,3,4 are respectively the dipolar module of N, S, have only when workpiece contacts the module of opposed polarity simultaneously to produce suction, so big workpiece 1 can be lived by sticking, then there is not suction substantially than small workpiece 2, therefore more in the application of Milling Process field, and use less in the grinding field.
(3) summary of the invention
At existing electric permanent-magnet suction disc module general all bigger, be unsuitable for the shortcoming of sticking than small workpiece, the utility model provides another panel type electric permanent-magnet suction disc, it can realize the absorption to little shape workpiece, and is applied widely.
Its technical scheme is such: it comprises electric permanent-magnet suction disc, described electric permanent-magnet suction disc comprises permanent-magnet steel, reversible magnet steel, coil, pole piece, it is characterized in that: described electric permanent-magnet suction disc upper surface is coated with panel, and described panel is inlayed according to needed distance between two poles size by utmost point piece, horizontal stripe, antifreeze plate with every the magnetic filler and formed.
In the said structure of the present utility model, the setting of panel makes in the electric permanent-magnet suction disc pole piece and the formed dissimilar polarities magnetic force of peripheral housing be evenly distributed on the panel, make the utmost point piece and the horizontal stripe that are in the antifreeze plate both sides produce different magnetic, can significantly reduce the distance between two poles of dissimilar polarities like this, thereby guarantee and can adsorb brute force than small workpiece, applied widely.
(4) description of drawings
The structural representation that Fig. 1 overlooks for existing electric permanent-magnet suction disc;
The structural representation that Fig. 2 analyses and observe for the utility model front view;
Fig. 3 is a vertical view of the present utility model;
Fig. 4 is that the A-A of Fig. 2 is to cutaway view.
(5) specific embodiment
See Fig. 2, Fig. 3, Fig. 4, the utility model comprises electric permanent-magnet suction disc and panel, electric permanent-magnet suction disc comprises permanent-magnet steel 10, reversible magnet steel 7, coil 8 and pole piece 9, between annexation identical with the common electrical permanent-magnet suction cup structure, belong to prior art, electric permanent-magnet suction disc is fixed on housing 12 bottoms by screw, and the electric permanent-magnet suction disc upper surface is coated with panel, and panel is inlayed according to needed distance between two poles size by utmost point piece 13, horizontal stripe 5, antifreeze plate 6 with every magnetic filler 11 and formed.
Below in conjunction with accompanying drawing the course of work of the present utility model is described: after electric permanent-magnet suction disc partly magnetizes the generation conducting magnetic line of force, pole piece 9 and peripheral housing 12 form dissimilar polarities magnetic force in electric permanent-magnet suction disc, be evenly distributed on the panel, make the utmost point piece 13 and the horizontal stripe 5 that are in antifreeze plate 6 both sides in the panel produce different magnetic, thereby the workpiece that comes close to or in contact with panel is produced holding force, realization is to the clamping of workpiece, otherwise electric permanent-magnet suction disc is partly demagnetized, correspondingly faceplate part fails to form dissimilar polarities magnetic force, thereby workpiece is unloaded from panel.The electric permanent-magnet suction disc part forms the conducting magnetic line of force and the not conducting magnetic line of force by magnetization, demagnetization process is identical with general electric permanent-magnet suction disc part.
Claims (1)
1. panel type electric permanent-magnet suction disc, it comprises electric permanent-magnet suction disc, described electric permanent-magnet suction disc comprises permanent-magnet steel, reversible magnet steel, coil, pole piece, it is characterized in that: described electric permanent-magnet suction disc upper surface is coated with panel, and described panel is inlayed according to needed distance between two poles size by utmost point piece, horizontal stripe, antifreeze plate with every the magnetic filler and formed.
