Problems solved by technology

The electro-hydraulic servo valve is a key component that determines the performance of the electro-hydraulic servo system. Due to its high precision requirements and difficult manufacturing, it cannot be mass-produced at present, and the bottleneck restricting the mass production of electro-hydraulic servo valves is the slide valve grinding process.
The efficiency and quality of sliding valve grinding are strongly dependent on the technical level and in-depth research of the operator, so the human factors in the grinding process are obviously affected

Abstract

The invention relates to a device for automatically grinding and detecting a square window of a valve sleeve of a servo valve. A central spindle is installed in a main hole of a clamp body and is sleeved with the valve sleeve of the servo valve and an LVDT sensor, the upper end surface of the LVDT sensor is fixedly connected with the lower end face of the valve sleeve of the servo valve, a conversion circuit is arranged in the clamp body corresponding to the LVDT sensor, a strut is fixedly connected to the upper face of the clamp body, one end of a pressure plate is connected to the strut, andthe other end of the pressure plate is connected to the upper part of the central spindle in a sleeving manner; an M-gear type nut is screwed to the upper end of the central spindle and is connectedto the upper plane of the pressure plate, the pressure plate is fixedly connected to a motor 1, and a gear on the first motor is in meshed transmission connection with the M-gear type nut; a spring isconnected between the pressure plate and the valve sleeve of the servo valve; and one end of a grinding bar extends into the square window of the valve sleeve of the servo valve, a rack on the otherend of the grinding bar is in engaged connection with a gear on a second motor. By means of the device, the grinding precision and efficiency can be effectively improved, and a foundation is laid forsolving the bottleneck of a valve sleeve mated grinding process and realizing the mass production of an electro-hydraulic servo valve.

Description

technical field [0001] The invention relates to an electro-hydraulic servo, in particular to a grinding and detection device for the electro-hydraulic servo. Background technique [0002] The electro-hydraulic servo system has a high response frequency, high power-to-weight ratio and torque-to-inertia ratio, and is widely used in control fields such as aviation, aerospace, and ships. The electro-hydraulic servo valve is a key component that determines the performance of the electro-hydraulic servo system. Due to its high precision requirements and high manufacturing difficulty, it cannot be mass-produced at present. The bottleneck restricting the mass production of electro-hydraulic servo valves is the sliding valve grinding process. The efficiency and quality of sliding valve grinding are strongly dependent on the technical level and in-depth research of the operator, so the human factors in the grinding process are obviously affected. Therefore, there is a need for an aut...
