Abstract
With the development of science and technology, application and design of heating quenching machine five axis surface induction is becoming more and more frequent, the development of advanced cutting technology is constantly from the new achievements of science and technology in the new starting point. At present, five axis surface induction hardening machine design technology has played an important role in the manufacture of electronic technology, computer technology and robot. In any case, five axis surface induction hardening machine design to improve the level and quality of welding. We will only quenching technology combined effectively in order to better promote the development of new technology for CNC machine welding technology, the NC quenching machine tool design is very important for solving this problem.The structure and design of transmission of the Longmen type flame cutting beam and the flame cutting machine head of mechanical part X, Y direction is designed. Mechanism design of beam is mainly determined the structure of the transmission device, the selection and calculation of main drive test, finally the parts selection check. The major was calculated on the rolling of screw strength and transmission efficiency etc.. Was improved and the structure of existing beam in the design of the connection problem. Flame cutting head is the speed control based on motion by using screw transmission device, good results were achieved after verification, to achieve the desired objective.
Keywords: five axis linkage, mechanism design, the design of five axis surface induction hardening machine
