Abstract

The invention discloses a microelectronic controlled hydraulic high-precision feeding system. The microelectronic controlled hydraulic high-precision feeding system comprises a microelectronic controller, a hydraulic system and a displacement sensor. The hydraulic system comprises an oil cylinder and hydraulic valves. The hydraulic valves comprise an inlet valve arranged at the inlet of the oil cylinder and an outlet valve arranged at the outlet of the oil cylinder. The inlet and the outlet of the oil cylinder are further provided with a pressure sensor for detecting the pressure of the inlet and the pressure of the outlet. The displacement sensor and the pressure sensor are connected to the input end of the microelectronic controller. The hydraulic valves are connected to the output end of the microelectronic controller through electrical apparatus elements. The high efficiency and energy conservation of the hydraulic system and the accurate guarantee of closed-loop control are utilized, so that the precision is not affected after the feeding system is used for a long time, and the energy is saved. Moreover, the overall structure is simple, and the maintenance and repair are convenient.

Description

technical field [0001] The invention belongs to the technical field of feeding systems, in particular to a microelectronic control hydraulic high-precision feeding system. Background technique [0002] The feed system is an automatic control system that uses the position and speed of moving parts as the control quantity. It is a typical mechatronic system, mainly composed of control units, drive components, detection and feedback units, and mechanical execution components. composition. [0003] In the high-precision feeding system, the screw system is currently used as the actuator. The screw system has the characteristics of high feeding accuracy and easy control, but there are also obvious shortcomings, such as: the structure is relatively complicated, and after long-term use Abrasion makes the gap between screw rod and screw nut inconsistent, which affects the overall feeding accuracy, and maintenance and repair are relatively complicated, which ultimately makes the cost...
