ABSTRACT
In order to solve the problem of the upper and lower materials in the seamless tube, an economical automatic upper and lower materials mechanism is designed, which effectively improves the degree of production automation. This new type of automatic operation device can imitate human hands according to the operation requirements. According to the pre-determined procedures and tracks through the hydraulic system to achieve the capture and handling operation to complete certain operations.
This design of the four-degree-of-freedom automatic up and down material mechanism according to the specified action order, using the basic theory, basic knowledge and related mechanical design expertise, complete the design of the manipulator, and draw the necessary assembly diagram, hydraulic system diagram,. The mechanical structure of the manipulator is composed of cylinder, screw, guide cylinder and other mechanical devices; In the hydraulic transmission mechanism, the manipulator's arm is telescopic with a retractable oil cylinder, the wrist is rotated with a rotary oil cylinder, the vertical column is rotated with a rack oil cylinder, the manipulator is lifted with a lifting oil cylinder, and the vertical column is moved horizontally with a lateral moving oil cylinder; By controlling the switch of the solenoid valve, the manipulator is controlled to carry out the corresponding action cycle. When the continuous stop button is pressed, the manipulator automatically stops moving after completing an action cycle.
