According to the technical scheme, the material transferring and clamping
robot comprises a vehicle body, a mechanical arm is installed on the vehicle body, a
rotating disc is rotationally connected to the end, located in a containing groove, of the vehicle body, a plurality of assembling grooves are formed in the
rotating disc, a closing plate is rotationally connected to the vehicle body, and a sliding frame is slidably connected to the closing plate; the vehicle body is provided with a
butt joint block at the placing groove, and the mechanical arm is provided with an
insertion block corresponding to the
butt joint block; by means of the
rotating disc, the mechanical arm can replace different clamping claws conveniently, the working efficiency is improved, when the motor drives the rotating disc to rotate, the
cam is driven to rotate, the sliding frame slides to the position above the proper storage groove, more dust is prevented from entering other storage grooves, meanwhile, materials are prevented from falling into the storage grooves in the clamping process, and the working efficiency is improved. And a butt-joint
pipe on the butt-joint block and a butt-joint
pipe on the
insertion block communicate with each other, and lubricating oil in an oil groove in the transmission end of the mechanical arm is replaced or impurities are removed through work of an
oil pump.
