Abstract

The invention discloses a square throttling hole linear cutting positioning tool of a ultrahigh-precision servo valve sleeve. The valve sleeve has a shaft hole; a space coordinate system is built with the center axis of the shaft hole as an X axle; a Y axle is perpendicular to the X axle in the horizontal direction; and a Z axle is perpendicular to the X axle in the vertical direction. The positioning tool is characterized by comprising a stopper, a pair of V-shaped grooves and an axial positioning nail; one end surface of the stopper is parallel to a Y-Z axle plane; the pair of V-shaped grooves are positioned on one side of one end surface of the stopper; the center axis of the pair of V-shaped grooves is relatively perpendicular to one end surface of the stopper; the valve sleeve is positioned in the pair of V-shaped grooves; and one end of the axial positioning nail is connected with the shaft hole of the valve sleeve, and the other end is contacted with one end surface of the stopper. The positioning tool has the following advantages: the valve sleeve can be quickly and accurately clamped and positioned; the influence caused by manufacturing errors of procedures before cutting a square hole of the valve sleeve is reduced or even eliminated; and the coplanarity of a square hole throttling working edge machined by linear cutting is guaranteed to achieve high precision.

Description

technical field [0001] The invention relates to the technical field of ultra-high-precision tooling fixtures, in particular to an ultra-high-precision servo valve sleeve square orifice line cutting and positioning tooling and a method thereof. Background technique [0002] Electro-hydraulic servo valves are the core components of hydraulic servo control systems widely used in aviation, aerospace and other fields. Spool valve couplers (spool valve sleeves) are key parts of servo valves. The fit gap with the valve sleeve, the size and shape of the throttling working side, and their mutual position and other shape and position error accuracy directly affect the static and dynamic characteristics of the servo valve. Therefore, the design of the valve sleeve that determines the main working characteristics of the servo valve High demands are placed on the machining quality of the working edge of the hole throttling. [0003] Due to the working characteristics of the spool valve ...
