Abstract
The utility model relates to a petal shape electrophoresis magnetic sucking disc, which is characterized in that three to seven circular annular magnetic yokes are arranged on a circular bottom plate which is provided with an outlet box, and a circular reversible magnet is arranged at the center part of each circular annular magnetic yoke, wherein, a circular annular exciting winding is sheathed on the periphery of a circular reversible magnet. A circular cover plate which is provided with a circular groove at the upper part is arranged on the circular reversible magnet, and tile-shaped main magnets with same width and same thickness are embedded between the circular cover plate and the circular annular magnetic yoke, cast and encapsulated by oxygen resin. The utility model has the advantages that the effective magnet pole area of the sucking disc is enlarged, the sucking force to the suction of plate-shaped workpieces is great, and the anti-fluttering ability is strong.
Description
The utility model external form belongs to H01F magnet class technology, particularly relates to a kind of petal electric permanent-magnet suction disc.
In recent years, new electric permanent magnetism technology is because its energy consumption is low, the life-span long running reliable and series of advantages extensive use at home and abroad such as power-off protection effect is arranged itself.But at present because reasons in structure, generally all make rectangle and bigger length-width ratio is arranged, for example French braillon PEP-3 of company type, 1.25 tons of electric permanent-magnet suction disc length-width ratios are 2, and domestic DYQ-25 type, 2.5 tons of electric permanent-magnet suction disc length-width ratios are 3.Therefore also exist not enoughly, make that promptly the anti-vibration ability of sucker each all directions of sucker adhesive plane when picking up than the large tracts of land workpiece is inconsistent, in that direction of minimum often because chatter or lay particular stress on the workpiece that causes non-load-bearing capacity to cause and fall.Find out that from above-mentioned analysis the ideal form of sucker should be circular or be bordering on circle.Known from institute, the operation principle of magnetic suction disc is that N and two kinds of magnetic poles of S are arranged on the sucker, and magnetic flux is got back to the S utmost point from the N utmost point through workpiece, and to the sticking of plate-like workpieces the time, the width of magnetic pole is subjected to the thickness of workpiece restriction.Improve the essential length that increases magnetic pole of suction, and the circular magnetic chuck center there is very big dead space; Because of reasons in structure, electric permanent-magnet suction disc is difficult to make concentric-ring pattern again.
The purpose of this utility model is to overcome the deficiency in the known technology and provides a kind of anti-vibration ability to improve and increase the petal electric permanent-magnet suction disc of sucker effective magnetic pole area with the suction that improves it.
The purpose of this utility model is achieved in that
Having the annular yoke that 3-7 annular is installed on the circular bottom plate of outlet box, place the circular reversible magnetic body that its outer race is equipped with the annular magnet exciting coil at the central part of each annular yoke, being installed on it on circular reversible magnetic body has the circular cover of circular groove, and cast is packaged with epoxide resin after being inlaid with watt shape master magnet of wide equal thickness between circular cover and the annular yoke.
The utility model has following accompanying drawing:
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is looking up of Fig. 1 and the structural representation that watt shape master magnet of one is carried out section.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
With reference to Fig. 1, at the circular mild steel base plate that has outlet box 7 the annular yoke of being made by low-carbon steel material 2 of 5-7 annular is housed for 1 time, present embodiment is selected the circular yoke of 5 annulars for use, with reference to Fig. 2, is made of petal them.Central upper in each annular yoke is placed the circular reversible magnetic body of being made by aluminium nickel cobalt material 3, is set with annular magnet exciting coil 4 in the outer ring of each circular reversible magnetic body; Parallel with one another between coil and the coil.The circular cover 5 that is installed on it and has circular groove in the bottom of each circular reversible magnetic body, make the anchor ring of the groove on the circular cover form an annular magnetic pole and form polar ring that their area is the effective area of generation suction with the bottom surface of annular yoke 2.Connect and above-mentionedly between circular cover 5 and annular yoke 2, also be inlaid with the wide equal thickness watt shape master magnet of making by NdFeB material 6, and casting epoxy resin encapsulates.
Advantage and the good effect that the utlity model has be, its elementary cell be circular, Profile is similar to round electric permanent-magnet suction disc, has better antivibration to quiver than rectangle electric permanent-magnet suction disc Ability. Again because it selects circular reversible magnetic body, so have maximum excitation efficiency. It is the circular bare bones of shell-type on structure, thereby its rigidity is better than the suction of rectangular configuration Dish. In addition, the utility model also have simple in structure, use reliable, cost with And the characteristics of minimizing maintenance.
