Embodiment Construction

[0044] The present invention will be further elaborated below in conjunction with embodiment.

[0045] Such as Figure 1-3 As shown, the longitudinal position adjustment process: the upper computer sends a command signal, the lifting control motor 1 drives the rotation of the lifting screw 6, which can drive the longitudinal position of the lifting plate 4, and the laser displacement sensor 2 generates a feedback signal, so that the lifting adjustment forms a position closed-loop control , so as to automatically, quickly and accurately track the longitudinal position of the beam sensor 9 . In order to ensure the stability of the screw rotation, a directional bearing 8 is provided at its end; the four longitudinal adjustment slide rails 5 reduce the possibility of lifting stagnation and ensure the flexibility of movement.

[0046] Such as Figure 1-3 As shown, the horizontal position adjustment process: the upper computer sends out a command signal, the inclination adjustment...

Abstract

The invention relates to a servo valve electromagnetic zero position automatic accurate quantification regulation and control device and method. The device comprises a light beam sensor, a support, a control driver, a lifting control motor, a lifting regulation mechanism and a dip angle regulation mechanism. The support is of a four-supporting-leg structure, and four dip angle adjusting mechanisms are installed below the four supporting legs of the support respectively. The control driver, the lifting control motor and the lifting adjusting mechanism are installed on the support, the light beam sensor is installed on the lifting adjusting mechanism, and the connecting line of every two adjacent supporting legs is parallel to or perpendicular to the light beam direction of the light beam sensor. The lifting control motor is used for driving the lifting adjusting mechanism to drive the light beam sensor to reach a preset longitudinal position under the control of the control driver, and the four dip angle adjusting mechanisms adjust the horizontal position of the light beam sensor by adjusting the heights of the four supporting legs under the control of the control driver. And the light beam of the light beam sensor and the working air gap of the torque motor in the tested servo valve are in a relative horizontal state.

Description

technical field [0001] The invention relates to a servo valve electromagnetic zero position control technology, in particular to an automatic and precise quantitative control device and method for multi-standard servo valve electromagnetic zero positions. Background technique [0002] The electro-hydraulic servo system is widely used in the fields of aviation, aerospace, shipbuilding, metallurgy, and chemical industry. played a vital role. At present, there is no auxiliary device available for the adjustment of the electromagnetic zero position of the torque motor during the performance debugging of the electro-hydraulic servo valve. It mainly relies on manual judgment, trial and error, and adjustment. The debugging efficiency of the servo valve. [0003] When the torque motor of the servo valve is at the electromagnetic zero position, its upper and lower air gaps are of the same size. Therefore, to regulate the electromagnetic zero position, accurate measurement of the ai...
