The robot command controls the piston rod of the telescopic cylinder 2 to extend out, and the execution action is transmitted through the floating joint 6 to drive the guide rod 7 to extend out. The guide rod 7 drives the 3 finger limiting rods 9 to extend outwards, the spring 10 is compressed, the finger limiting rods 9 drive the finger blocks 11, the copper patches 12 and the nylon patches 13 to expand and support the inner holes of the shell parts, and the material grabbing action is completed;

the material discharging process comprises the following steps: when the robot master control satisfies the blowing condition, the robot instruction control telescopic cylinder 2 piston rod withdrawal, and the executive motion drives guide bar 7 withdrawal through the transmission of floating joint 6. The elastic potential energy generated by the compression of the front spring 10 enables the finger limiting rod 9 to retract, the finger limiting rod 9 drives the finger block 11, the copper patch 12 and the nylon patch 13 to be folded, and the claw of the gearbox shell is separated from parts of the shell to finish the material placing action.
