According to the technical scheme provided by the utility model, the permanent magnetic chuck comprises a chuck body and a magnetic platform located on the chuck body, wherein the magnetic platform is composed of a plurality of permanent magnets; the magnetic platform is internally provided with a transmission mechanism for controlling the permanent magnets to rotate. The novel permanent magnetic chuck is characterized in that each permanent magnet is formed by compounding a neodymium iron boron layer and a ferrite layer; the neodymium iron boron layer is arranged inside; the ferrite layer is arranged outside. The novel permanent magnetic chuck has the beneficial effects that each permanent magnet is formed by compounding the neodymium iron boron layer and the ferrite layer; the range of the needed magnetic field strength can be adjusted randomly by changing the thicknesses or the area ratio of the neodymium iron boron layer and the ferrite layer; the neodymium iron boron layer is arranged inside and the ferrite layer is arranged outside so that the ferrite layer is directly contacted with the workpiece and the neodymium iron boron layer is prevented from being corroded, and furthermore, the service life is long.
Description
Technical field
The utility model relates to machining clamping device field, is specifically related to the permanent magnetic chuck of holding workpiece on Metal Cutting Machine Tool.
Background technology
In field of machining, be widely used the Metal Cutting Machine Tools such as milling machine, planer, boring machine and grinding machine, these conventional Metal Cutting Machine Tools are fixed on workpiece on lathe by hold assembly.Traditional hold assembly adopts the parts such as pressing plate, chuck to carry out the fixing of workpiece conventionally, but the deficiencies such as the clamping of these traditional hold assemblies is inconvenient, the clamping time is long, effect is low, in order to overcome above-mentioned defect, there is a kind of new hold assembly---magnetic suction disc.Existing magnetic suction disc has two kinds of permanent magnetic chuck and magnechucks conventionally, the magnetic-adsorption workpiece that permanent magnetic chuck produces by permanent magnet, and permanent magnet adopts NdFeB material to make mostly, but this kind of permanent magnetic chuck is when magnetic field intensity surpasses 3000GS, comparatively difficult to the dismounting of workpiece, and the corrosion resistance of Nd-Fe-B permanent magnet is poor, when workpiece is directly installed on Nd-Fe-B permanent magnet, corrosive substance on workpiece, by cause certain burn into damage to permanent magnetic chuck, shortens the service life of permanent magnetic chuck.
Summary of the invention
The purpose of this utility model is to provide that a kind of magnetic field intensity is moderate, the novel permanent magnetic sucker of long service life.
For solving the problems of the technologies described above, its technical scheme is:
A sucker, comprises disk body, is positioned at the magnetic platform on disk body, magnetic platform is comprised of a plurality of permanent magnets, and magnetic platform inside is provided with the transmission mechanism of controlling permanent magnet rotation, it is characterized in that: permanent magnet is composited by neodymium iron boron layer and ferrite layer, neodymium iron boron layer is interior, and ferrite layer outside.
Further, a plurality of permanent magnets are distributed on on one or more circumference in annular array mode.
Further, permanent magnet is circular or fan-shaped.
Further, on two sides of permanent magnet, be equipped with groove, two groove combination in the adjacent side of two adjacent permanent magnets form " dovetail " type groove.
The beneficial effects of the utility model are:
1, the permanent magnet in this novel permanent magnetic sucker adopts ferrite layer and neodymium iron boron layer to be composited, by changing ferrite layer and neodymium iron boron layer thickness or Area Ratio, can within the scope of required magnetic field intensity, adjust arbitrarily, neodymium iron boron layer is interior, ferrite layer outside, ferrite layer directly contacts with workpiece, has avoided the corrosion of neodymium iron boron layer, long service life.
2, a plurality of permanent magnets are evenly distributed on on one or more circumference, make workpiece stressed more even, good by more stable, the difficult drop-off of the workpiece after holding, result of use.
3, two groove combination in the adjacent side of two adjacent permanent magnets form " dovetail " type groove, and " dovetail " type groove is more convenient to maintenance, maintenance when improving service behaviour.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment mono-;
Fig. 2 is the distribution schematic diagram of permanent magnet annular array in the utility model embodiment bis-;
Fig. 3 is the structural representation of permanent magnet in the utility model;
Wherein Reference numeral is: 1-disk body, 2-magnetic platform, 3-permanent magnet, 4-ferrite layer, 5-neodymium iron boron layer, 6-groove, 7-" dovetail " type groove.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment mono-:
A sucker, comprises disk body 1, and this disk body 1 can be cylinder, square or cuboid.Disk body 1 top is provided with magnetic platform 2, the shape of this magnetic platform 2 is consistent with disk body 1, and magnetic platform 2 can be identical with the size of disk body 1, and size that also can magnetic platform 2 is less than disk body 1, magnetic platform 2 is comprised of a plurality of permanent magnets 3, and a plurality of permanent magnets 3 are distributed on and on disk body 1, form magnetic platform 2 in the mode of cross arrangement in length and breadth.On two sides of each permanent magnet 3, be equipped with groove 6, two grooves 6 in the adjacent side of two adjacent permanent magnets 3 are combined to form " dovetail " type groove 7, and " dovetail " type groove 7 can be used for installing other clamping parts or other purposes.Being shaped as of this permanent magnet 3 is circular or fan-shaped, by ferrite layer 4 and neodymium iron boron layer 5 double-layer structure, be composited, neodymium iron boron layer 5 is interior, ferrite layer 4 outside, neodymium iron boron layer 5 contacts with disk body 1, ferrite layer 4 contacts with workpiece, and because neodymium iron boron layer 5 does not directly contact with workpiece, so neodymium iron boron layer 5 is difficult for being corroded, damaging; In addition, by changing ferrite layer 4 and neodymium iron boron layer 5 both thickness or Area Ratio, can within the scope of required magnetic field intensity, adjust arbitrarily the magnetic field intensity of magnetic platform, thereby meet the process requirements to the workpiece of different size.In addition, magnetic platform 2 inside are provided with the transmission mechanism of controlling permanent magnet 3 rotations, by controlling this transmission mechanism, can realize the upset of permanent magnet 3.
During the utility model work, first workpiece is placed on the magnetic platform 2 of workbench, by the permanent magnet 3 on magnetic platform 2, adsorb workpiece, by regulating neodymium iron boron layer 5 and ferrite layer 4 both thickness or Area Ratio, can within the scope of required magnetic field intensity, adjust arbitrarily the magnetic field intensity of magnetic platform 2, meet process requirements, after workpiece processes, the transmission mechanism of controlling 2 internal control permanent magnet 3 rotations of magnetic platform, can take off workpiece easily from magnetic platform 2.The magnetic field intensity that in the utility model, permanent magnet 3 produces is moderate, and neodymium iron boron layer 5 directly do not contact with workpiece, be difficult for being corroded, and long service life.
Embodiment bis-
On the basis of embodiment mono-, the arrangement mode of permanent magnet 3 should be distributed on on one or more circumference in annular array mode for a plurality of permanent magnets 3, being permanent magnet 3 is distributed on and on disk body 1, forms magnetic platform 2 in annular mode, in annular mode, refer to that permanent magnet 3 is arranged in by disk body 1 end face on the circular circumference centered by a bit, evenly distributed on the circle of the different radii that wherein permanent magnet 3 can be on disk body 1 end face, can a circle or the form of multi-turn arrange.Change the arrangement mode of permanent magnet 3 into annular array mode uniform, its object is to make workpiece stressed more even, good by more stable, the difficult drop-off of the workpiece after holding, result of use.
