Servo hydraulic jacksStudent Name: Shi Junyong Class: 068105322Supervisor : Gao YanfengAbstract: Digg this liter four-designed system, the main parameter is the high per jack about 1000mm, the maximum stroke is 400mm, the maximum load of 20t. Jack load due to a larger location with high precision, thus lifting speed should not be too large, the maximum lifting speed should be controlled within the 60mm/min.Works, the two four-way solenoid valve of the solenoid working state is controlled by the microcontroller, when the solenoid valve energized, the valve Left access system, oil by the solenoid valve and balancing valve into the cylinder under the cavity, so jack up, and from fuel tanks on the cavity flow, flow through solenoid valve and filter tank back in, then the role of balancing valve is equivalent to a one-way valve; the other hand, When the solenoid valve power, the valve access system the right position, oil flows through valve cylinder on the cavity, when the chamber pressure reaches a certain value, the upper balance valve access system, when a balance acts as a throttle valve, the oil flow from the fuel tank under the cavity, by balancing valve, solenoid valve and filter flow back to tank. In order to achieve a lifting jack for the function, and have overload protection and power protection.In order to adapt to the complex work piece surface, jack the table should be used with the piston rod connected to rotate connections made at work when lifting systems, hydraulic jack table with the surface shape can be adjusted freely rotate, so when the piston rod at the top of the design Insert the ball, and form a rotating table viceAs the size of a long grating, the piston and piston rod to place the grating made of hollow shape. Work light emitting devices with photosensitive elements for synchronous movement with the piston, the bottom grating fixed to the bottom cover fixed, light source and grating by reading the relative displacement of the first into a digital signal is passed to the microcontroller.Keywords: 4 Synchronous Lift SCM GratingSignature of supervisor:
