Precise workpiece taking system for robot polishing

The invention relates to the field of robots, in particular to a precise workpiece taking system for robot polishing. The precise workpiece taking system comprises a feeding mechanism, a steering mechanism, a loading mechanism, a position correcting mechanism and a grabbing mechanism; limiting protrusions are clamped with limiting edge grooves, so that a base plate and limiting blocks rotate synchronously, and the situation that when a rotating barrel rotates, the base plate does not rotate synchronously along with the rotating barrel, and the effect of workpiece angle adjustment cannot be achieved is prevented. a short supporting rod is of a three-section structure and is matched with a camera to collect picture information to execute an operation instruction, and the stability and accuracy of iron casting workpiece operation can be guaranteed; rigid connection is achieved through the clamping effect between clamping blocks and clamping grooves, and therefore the stability of the grabbing mechanism in the mo
