Automatic system for installing nut on clamping piece

The utility model discloses an automatic system for installing a nut on a clamping piece, which is characterized in that an execution motor vertically slides on a base to drive a rotating rod to vertically slide, so that a movable plate vertically slides, and the movable plate can adsorb the clamping piece or the nut; the rotating rod is driven to rotate through power output by the output end of the execution motor, so that the movable plate rotates, the movable plate can move clamping pieces or nuts conveyed by the clamping piece conveying belt or the nut conveying belt to the assembling position, and the clamping pieces or the nuts are assembled through transverse sliding of the sliding block on the base. The clamping pieces with different sizes can be fixedly assembled between the fixed block and the sliding block, the situation that the clamping pieces with different sizes need to be assembled on different assembling systems is avoided, and the repeated utilization rate of the clamping piece nut assemblin
