Adsorption mechanism for feeding and discharging device of lapping grinding machine

The utility model relates to auxiliary equipment of a lapping grinding machine, in particular to an adsorption mechanism for a feeding and discharging device of the lapping grinding machine. A cantilever of the adsorption mechanism for the feeding and discharging device of the grinding bed is arranged at one end of a fixed element; the adsorption mechanism is provided with a long-strip-shaped adsorption base. The adsorption seat is provided with at least one row of through holes arranged along the length direction of the adsorption seat; a permanent magnet suction-assisting block is placed in the through hole; the plurality of permanent magnet suction-assisting blocks jointly form an adsorption mechanism for adsorbing a workpiece; the lower end face of the adsorption base is located on an arc-shaped face attached to a workpiece, and a rectangular through groove is formed in the bottom of the arc-shaped face. One side of the adsorption base is provided with a protrusion arranged in the length direction of the
