Circular electro-permanent magnetic chuck for vertical lathe

Abstract

The invention relates to a circular electro-permanent magnetic chuck for a vertical lathe, in particular to a magnetic fixture for a vertical lathe for realizing rapid machining by way of taking the place of grinding by turning. The circular electro-permanent magnetic chuck for a vertical lathe comprises a chuck body, magnetic poles, a magnetic steel, a magnet exciting coil and a magnetic cushion, wherein a plurality of strip-shaped holes are arranged above the chuck body, the magnetic poles are pressed on the magnetic steel, and the magnet exciting coil is arranged on an outer ring of the magnetic steel; the magnetic cushion is arranged above the magnetic poles, the magnetic cushion and the magnetic poles are integrated and arranged in the strip-shaped holes above the chuck body by bolts, and the wires of the magnetic poles are led out from the chuck body. The magnetic poles are straight-strip-shaped magnetic poles with same width. The two adjacent polarities of the straight-strip-shaped magnetic poles are opposite, and even magnetic poles are arranged on a same circumference in pairs. The invention has strong suction force, can satisfy the requirement for machining, has good retentivity of accuracy and stable state in the process of machining, can satisfy the requirement for finish machining, exempts the process of grinding, does not cause the phenomenon of divergent magnetic field, and can effectively avoid the influence of magnetic fields on cutting tools and iron filings in the process of machining.

Description

technical field [0001] The invention relates to a circular electro-permanent magnetic sucker for vertical lathes, in particular to vertical lathes using magnetic clamps for realizing rapid cutting with lathes instead of grinding. Background technique [0002] At present, with the development of the wind power industry, wind power companies have increased demand for wind power bearings, and the wind power bearing processing industry is in urgent need of a high-precision, high-efficiency turning fixture. One is to solve the problem of low processing efficiency. It is necessary to realize the goal of replacing the grinding process with the finishing process and effectively reduce the processing time; the other is to solve the unavoidable radial deformation caused by the chuck clamping thin-walled parts in the traditional turning process. The problem of deformation; the third is to solve the problem that one clamping can complete multi-faceted processing, so as to prevent proce...
