Abstract
The invention relates to an electric permanent magnetic holding device for abrasive machining, in particular to an electric permanent magnetic holding device which can carry out online demagnetizationon a workpiece to be processed. A main pole made from rear earth materials is installed on a groove-shaped bottom plate, a coil used for the operations of magnetization and demagnetization is inlaidon the outer face of the main pole, a leading pole made of metal is installed on the main pole, and a panel which comprises magnetic conductible materials and non-magnet conductible materials and enables a magnetic field to be uniformly distributed is installed on the leading pole. The invention has the advantages of low energy consumption, high accuracy, no loss of field during current failure inworking, and online demagnetization on the workpiece.
Description
Technical field
The present invention relates to a kind of electric permanent magnetic holding device for abrasive machining, especially can carry out the electric permanent magnetism anchor clamps of online demagnetization institute's processing work.
Background technology
At present, the magnechuck holding workpiece is used in grinding usually, and ubiquity: power consumption is high, and precision is low, and accident power-off loss of excitation shortcoming such as can have an accident can't realize institute's processing work is carried out online demagnetization.
Summary of the invention
There is power consumption high in order to solve existing magnechuck, precision is low, the problem that the accident power-off loss of excitation can have an accident, this electric permanent magnetic holding device for abrasive machining provided by the present invention, its characteristics are: it is low to consume energy, than traditional electrical magnetic-disc energy-conservation 95%, the precision height, can reach the micron order machining accuracy, outage can loss of excitation in the work, can carry out online demagnetization to workpiece.
The technical solution adopted for the present invention to solve the technical problems is:
The main pole that rare earth material is made is housed on the grooved base plate, the main pole outside is embedded with the coil that is used to fill the demagnetization operation, metal leading pole is housed above the main pole, is equipped with above the leading pole and makes the equally distributed panel of forming by permeability magnetic material and non-magnet_conductible material in magnetic field.
The present invention also can realize by following measure: as depicted in figs. 1 and 2, fixedly rare earth material main pole 4 and leading pole 3 respectively in the center of grooved base plate 1, be embedded with in the outside of rare earth material main pole 4 and leading pole 3 and fill degaussion coil 5, at rare earth material main pole 4 and installation panel 2 above the leading pole 3, permeability magnetic material 7 above the panel 2 and non-magnet_conductible material 8 constitute magnetic loop with grooved base plate 1, at the two ends of panel 2 installing hole 6 is set, is used for installing and fixing with plant equipment.
The invention has the beneficial effects as follows that it is low to consume energy, more energy-conservation 95% than traditional electrical magnetic-disc, the precision height can reach the micron order machining accuracy, and outage can loss of excitation in the work, can carry out online demagnetization to workpiece.
