Structural Design and PLC Control of the Machine Tool Manipulator

Abstract

Abstract.A kind of hydraulic-driven manipulator for machine tool is presented in this paper. Firstly, the manipulator's structure is designed and 3D model is built by using solidworks software. Secondly, the hydraulic system diagram for implementing the manipulator's sequences is established. Finally, control system of the machine tool manipulator is implemented based on PLC, and the experimental results show the correctness and feasibility of our design and control programs. Therefore, this can provide a certain referencing value for the practical production application. IntroductionThe industrial manipulator is a kind of automatic equipment, which can simulate the hand gestures of human been and achieve the automatic motion of grabbing, carrying and manipulation, according to the preset sequences, tracks and demands [1]. It is one of the most important equipments, which can realize the industrial production mechanization and automation [1,2]. Many applications demand manipulators with high degrees of repeatability, precision, and reliability. Therefore, some researches on the mechanical manipulator and its control have been done by many scholars [3][4][5]. In this paper, our designed the hydraulic-driven machine tool manipulator combined with CNC machine (machining centers, CNC milling machine, etc.) can form an automated production line to achieve processing (feeding, processing and automation of the cutting) without human interference.
