Surface finish grinding machine for outer arc surface of tile-shaped magnet

Abstract

The invention discloses a machine for finish grinding of the outer arc surface of a tile-shaped magnet. The machine for finish grinding of the outer arc surface of the tile-shaped magnet comprises a machine frame, wherein a conveying device used for conveying the magnet is arranged on the machine frame, an outer arc surface finish-grinding wheel used for grinding the outer arc surface of the magnet is arranged on the machine frame, and the outer circumferential surface of the outer arc surface finish-grinding wheel is a concave arc surface which is matched with the outer arc surface of the magnet; the conveying device comprises a feeding mechanism and a discharging guide rail which are located on the two sides of the outer arc surface finish-grinding wheel respectively, the feeding mechanism comprises a feeding guide rail, a sliding guide rail used for feeding is arranged at the front end, close to the outer arc surface finish-grinding wheel, of the feeding guide rail, a shifting block which is used for driving the magnet to move along the feeding guide rail is arranged at the rear end, away from the outer arc surface finish-grinding wheel, of the feeding guide rail, a feeding section which stretches out of the feeding guide rail and is lower than the feeding guide rail is arranged at the front end of the sliding guide rail, the upper end face of the feeding section is a convex arc surface which is matched with the inner arc surface of the magnet, a driving mechanism used for driving the sliding guide rail and the shifting block to move is arranged on the machine frame, and a tile-shaped magnet reversing and grabbing mechanism is arranged at the rear end of the feeding guide rail.

Description

technical field [0001] The invention belongs to the technical field of grinding processing equipment, and in particular relates to a precision grinding machine for grinding the outer arc surface of a tile-shaped magnet. Background technique [0002] Tile-shaped magnets are widely used at home and abroad at present, and my country is the world's largest exporter of magnetic tiles. After the pressing and sintering process of the magnetic tile is completed, it enters the grinding process. The grinding process of the magnetic tile includes: grinding the two planes of the chord width and the bottom plane, grinding the two ends of the shaft length, and inverting the inner and outer arcs of the shaft end. Corner, rough and fine grinding of inner and outer arc surfaces. In the fine grinding process of tile-shaped magnets, in order to achieve better grinding accuracy, it is best to grind tile-shaped magnets in small batches or individually, which leads to difficulty in feeding mater...

AI Technical Summary

Problems solved by technology

In the fine grinding process of tile-shaped magnets, in order to achieve better grinding accuracy, it is best to grind tile-shaped magnets in small batches or individually, which leads to difficulty in feeding materials, while the existing tile-shaped magnet grinding In the grinding tooling, the magnet needs to be manually clamped and positioned, resulting in low grinding efficiency

[0003] In addition, in the grinding process of the inner arc surface, outer arc surface and both sides of the chord width of the tile-shaped magnet, the axis of the tile-shaped magnet is parallel to the conveying track, while the grinding process of the two ends of the axial length of the tile-shaped magnet requires The two ends of the axial length of the magnet are located on both sides of the conveying track. Therefore, the magnet needs to be turned during the transfer process between the various grinding processes, and the existing tile-shaped magnet grinding equipment generally uses manual to complete the turn of the magnet. work, inefficiency
