Title Automatic Tool Change Robot Design - Horizontal Movement System Design

Abstract In today's large-scale manufacturing, CNC machining technology has been rapidly gaining popularity and development of CNC machine tools in the manufacturing sector has been more widely used. With automatic tool changer CNC machining centers in modern advanced manufacturing plays an increasingly important role, it can shorten the manufacturing cycle, improve the accuracy of product processing, suitable for flexible manufacturing. Automatic tool changer should satisfy the changing time is short, the tool high repeat positioning accuracy, knowledge knife, tool selection, reliable, simple and reliable tool change operation, small size, easy installation and maintenance requirements.

This article describes the automatic tool development status at home and abroad, as well as automatic tool changer applications, components, and automatic tool changer trends discussed. This paper focuses on automatic tool changer and horizontal movement of the robot system design. First, for the overall program demonstration， select the appropriate drive mode, drive mode and the overall structure: again this basis, the appropriate choice of rack and pinion, servo motor, ball screw linear guide ﹑ rolling and designed gearbox. Ultimately achieve the requirements of the subject.
