Design of a Gantry Robot Gripper for Machine Tool

Abstract

This paper describes the design of a gantry robot gripper for machine tool. In order to increase the productivity of the machine tool, the transfer speed of the gantry robot should be fast, and the displacement should be less than 1um when the workpiece is caught. In this paper, the gantry robot gripper is composed of a horizontal gripper, a vertical gripper and a gripper body. The horizontal gripper and the vertical gripper are at the angle of 90 degrees, and they are rotated 180 degrees. Thus, the gantry robot gripper can hold the work piece before machining, move it to the machine tool chuck position, rotate it 180 degrees, and hold the work piece after machining. The gripper was analyzed by using FEM(Finite Element Method), and was manufactured.
