Design of X-axis Beam with a Reinforcement Stand for A Three-axis Gantry Robot

Abstract

This paper describes an x-axis beam with a reinforcement stand for a three-axis gantry robot, which can attach and detach workpieces to and from a shelf. To design the x-axis beam, its structure with the reinforcement stand was analyzed. Based on the results of the structural analysis, the size of the reinforcement stand was determined, the x-axis beam with the reinforcement stand was designed, and a three-axis gantry robot with an x-axis beam and reinforcement stand was fabricated. A number of three-axis gantry robots were tested. The results revealed that the displacement at the chuck position was less than 100 mu m(0.1 mm), and the positions of the workpiece before and after machining were less than 200 mu m(0.2 mm). Therefore, the three-axis gantry robot can be used to attach and detach the workpiece from a computer numerical control(CNC) lathe.
