CNC lathe automatic loading and unloading mechanism design refueling
Abstract: With the needs of the development of industrial automation , robots are more and more important in industrial applications . .It solves the handling of heavy artifacts often appears in industrial production and frequent, monotonous operation for a long time, but also improves the production speed of workpiece, so the use of the manipulator is very efficient, and to a feeding manipulator is designed in this paper.
The design is mainly for refueling process CNC lathe automatic loading and unloading mechanism, grasp the two-dimensional or three-dimensional modeling of complex structures or NX UG CAD, master of a two-dimensional or three-dimensional engineering drawings using basic software and basic structural design, analysis of artifacts from the production line to the movement of the table. Rational design of mechanical refueling arm mechanism, and to consider the usefulness and application design and adjust arm depending on the raw materials in the size of the transfer structure of the different materials can be conveyed.Including mechanical transmission by a screw, horizontal linear guides, chains, sprockets and other components constituted robot arm, refueling robot, driven by a servo motor system, hydraulic system and so on and so on.
Through this design, the integrated use of theoretical knowledge of the past to improve the theory and practice and comprehensive analysis capabilities, the ability to develop complex structural engineering practice computer-aided design and manufacturing, training, and improve basic skills of CAD, the subject to train our actual three-dimensional design of mechanical parts and CNC machining process design mainly, but also understand the five-axis CNC machine tools and methods of use.
