ABSTRACT
Since the emergence of industrial robot technology in the middle of the 20th century, industrial robot machine tools have brought revolutionary changes to the mechanical manufacturing industry. The industrial robot machining has the following characteristics: good flexibility, high machining precision, high productivity, reducing the labor intensity of the operator, improving the working conditions, which is conducive to the modernization of production management and the improvement of economic benefits. Industrial robot machine tool is a kind of high mechanical and electrical integration product, which is suitable for machining many kinds of small batch parts, which have complicated structure and high precision requirements, which need frequently modified parts, and which are expensive and not allowed to be scrapped. Parts that require precision copying need to be shrunk Short production cycle for badly needed parts and 100% inspection required. The characteristics and application scope of industrial robot machine make it an important equipment for the development of national economy and national defense construction.
This design has studied the working part of the slide table of the industrial robot, and reported the principle of the industrial robot machine in China.
Keywords: industrial robot machine tool; industrial robot slide processing operation; lead screw
