Summary of the invention
The purpose of this utility model is to provide the grinding machine that a kind of clamping time is short, operating efficiency is high.
For solving the problems of the technologies described above, its technical scheme is:
A kind of grinding machine, comprise column, lathe bed, workbench and grinding head mechanism, workbench is fixed on lathe bed, it is characterized in that: workbench is provided with permanent magnetic chuck, the magnetic platform that described permanent magnetic chuck comprises disk body and is comprised of a plurality of permanent magnets, permanent magnet is composited by being positioned at the neodymium iron boron layer of internal layer and being positioned at outer ferrite layer, and disk body inside is provided with the transmission mechanism of controlling permanent magnet rotation.
Further, column is provided with height adjuster.
Further, a plurality of permanent magnets are distributed on on one or more circumference in annular array mode.
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 utility model arranges permanent magnetic chuck on workbench, permanent magnetic chuck is composited by neodymium iron boron layer and the outer field ferrite layer of internal layer, by permanent magnetic chuck, directly adsorb workpiece, without steps such as dismounting, clampings, so the clamping process time is short, operating efficiency is high.
2, by changing thickness or the Area Ratio of neodymium iron boron layer and ferrite layer, can within the scope of required magnetic field intensity, adjust arbitrarily, meet the needs of processing different size workpiece.
3, column is provided with height adjuster, has greatly increased grinding scope, can realize multi-angle grinding.
4, a plurality of permanent magnets are evenly distributed on same circumference, make workpiece stressed more even, good by more stable, the difficult drop-off of the workpiece after holding, result of use.
5, 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.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
, comprising column 1, lathe bed 2, workbench 3 and grinding head mechanism 4, column 1 is provided with vertical feeding mechanism, and this vertical feeding mechanism is connected with grinding head mechanism 4, and drives grinding head mechanism 4 to move both vertically; In addition, be also provided with height adjuster on column 1, this height adjuster is by four rod members, thread spindle, screw and hinged slide block is hinged forms, and by height adjuster, pillar 1 is mediated, and makes the gradient of workbench 3 meet the processing request of workpiece.Workbench 3 is fixed on lathe bed 2, and workbench 3 is provided with permanent magnetic chuck 5, and described permanent magnetic chuck 5 comprises disk body 6 and magnetic platform 7, and this disk body 6 can be cylinder, square or cuboid.Disk body 6 tops are provided with magnetic platform 7, the shape of this magnetic platform 7 can be consistent with disk body 6, also can be inconsistent, magnetic platform 7 can be identical with the size of disk body 6, also size that can magnetic platform 7 is less than disk body 6, magnetic platform 7 is comprised of a plurality of permanent magnets 8, and the mode that a plurality of permanent magnets 8 can array is distributed on and on disk body 6, forms magnetic platform 7, also can circle or the mode of annular be distributed on and on disk body 6, form magnetic platform 7.
Mode with circle or annular is that a plurality of permanent magnets 8 are distributed on on one or more circumference in annular array mode, being permanent magnet 8 is distributed on and on disk body 6, forms magnetic platform 7 in annular mode, in annular mode, refer to that permanent magnet 8 is arranged in by disk body 6 end faces on the circular circumference centered by a bit, evenly distributed on the circle of the different radii that wherein permanent magnet 8 can be on disk body 6 end faces, can a circle or the form of multi-turn arrange.Change the arrangement mode of permanent magnet 8 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.On two sides of each permanent magnet 8, be equipped with groove 11, two grooves 11 in the adjacent side of two adjacent permanent magnets 8 are combined to form " dovetail " type groove 12, and " dovetail " type groove 12 can be used for installing other clamping parts or other purposes.Being shaped as of this permanent magnet 8 is circular or fan-shaped, by ferrite layer 10 and neodymium iron boron layer 9 double-layer structure, be composited, neodymium iron boron layer 9 is interior, ferrite layer 10 outside, neodymium iron boron layer 9 contacts with disk body 6, ferrite layer 10 contacts with workpiece, and because neodymium iron boron layer 9 does not directly contact with workpiece, so neodymium iron boron layer 9 is difficult for being corroded, damaging; In addition, by changing ferrite layer 10 and neodymium iron boron layer 9 both thickness or Area Ratio, can within the scope of required magnetic field intensity, adjust arbitrarily the magnetic field intensity of magnetic platform 7, thereby meet the process requirements to the workpiece of different size.In addition, magnetic platform 7 inside are provided with the transmission mechanism of controlling permanent magnet 8 rotations, by controlling this transmission mechanism, can realize the upset of permanent magnet 8, make magnetic platform magnetize and demagnetization between exchange.
During the utility model work, first workpiece is placed on the magnetic platform 7 of workbench 3, by the permanent magnet 8 on magnetic platform 7, adsorb workpiece, by regulating neodymium iron boron layer 9 and ferrite layer 10 both thickness or Area Ratio, can within the scope of required magnetic field intensity, adjust arbitrarily the magnetic field intensity of magnetic platform 7, meet process requirements, after workpiece processes, control the transmission mechanism of magnetic platform internal control permanent magnet 8 rotations, thereby take off workpiece.In addition,, by the height of height adjuster adjustable strut 1, make the gradient of workbench meet the processing request of workpiece.Whole clamping process is simple to operate, the clamping process time is short, operating efficiency is high.
