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 [0001] The invention relates to an electric permanent magnet fixture for grinding, in particular to an electric permanent magnet fixture which can demagnetize a processed workpiece on-line. Background technique [0002] At present, the grinding process usually uses an electromagnetic chuck to hold the workpiece, which generally has the disadvantages of high energy consumption, low precision, accidents caused by accidental power failure and loss of magnetism, etc., and online demagnetization of the processed workpiece cannot be realized. Contents of the invention [0003] In order to solve the problems of high energy consumption, low precision, and accidents caused by accidental power failure and loss of magnetization in existing electromagnetic chucks, the electric permanent magnet fixture for grinding provided by the present invention has the following characteristics: low energy consumption, The traditional electromagnetic chuck saves energy by 95%, has h...
