In order to complete the belt polishing of aluminum parts,we studied the working principle and the process on robot belt polishing of aluminum,and calculated the specifications of tension cylin-der thrust,motor torque deviation adjusting and the drive sprocket of aluminum polishing system,and drew the three-dimensional drawings of aluminum belt constant force polishing machine. Polishing ma-chine system consists of robot and fixtures,belt sander,electric control system,two-way loading and unloading devices and other components. Based on the above analysis,the robot polishing constant polishing force control system was designed,which used double-loop control system that including the current feedback of converter and self-adjustment of cylinder thrust to achieve the constant control of polishing force,and had analog simulation of designed robot’s polishing trajectories to verify the ra-tionality and reliability of aluminum polishing machines.
