High-precision compression-configured device of electro-hydraulic servo valve armature component

Abstract

The invention discloses a high-precision compression-configured device of an electro-hydraulic servo valve armature component. The armature component comprises a baffle plate, a tube spring, an armature and a feedback rod which are subsequently arranged in a compression way. The compression-configured device comprises a central component, an adjusting pedestal, a tube spring auxiliary clamping guide mechanism and an armature floatation supporting and positioning mechanism, wherein a longitudinal through hole is formed in the central component; a positioning block used for placing a positioning plate is arranged in the through hole; a compression-configured hole for the tube spring to reach in is formed in the positioning block; the adjusting pedestal is matched with the longitudinal through hole in the central component through screw threads; the top part of the adjusting pedestal pushes against the positioning block to drive the positioning block to move up and down; the tube spring auxiliary clamping guide mechanism comprises at least two transverse through holes which are symmetrical about the longitudinal through hole; a slide positioning baffle block which can extend into the longitudinal through hole to push against the tube spring is glidingly formed in each transverse through hole; the armature floatation supporting and positioning mechanism comprises two elastic component mounting holes symmetrical about the longitudinal through hole left and right; an elastic component and an armature supporting and positioning block which is arranged on the elastic component are arranged in each elastic component mounting hole. The device can assist workers to configure the armature component in a compressing way, so that the compression-configured precision and the production efficiency are greatly improved.

Description

technical field [0001] The invention relates to a high-precision press fitting device for an armature assembly of an electro-hydraulic servo valve. Background technique [0002] The development of electro-hydraulic servo valves in the international professional field has gone through more than 50 years, and the application occasions are becoming more and more extensive. The electro-hydraulic servo valve is an important control element in the electro-hydraulic servo control system, which plays the role of electro-hydraulic conversion and power amplification in the system. The performance and reliability of the electro-hydraulic servo valve will directly affect the performance and reliability of the system. The guarantee of the performance and reliability requirements of the electro-hydraulic servo valve depends on the processing accuracy of the parts and the assembly accuracy of the components (parts). [0003] The armature assembly is the key component in the torque motor ...

AI Technical Summary

Problems solved by technology

[0004]However, the research and manufacture of servo valves in China is still in a relatively backward state

Especially in the mechanical feedback double nozzle baffle type electro-hydraulic servo valve, the press fit of the armature assembly is currently done manually. Due to the lack of special positioning fixtures and press fit fixtures, workers are more cumbersome and difficult to operate. For The control of precision also mainly relies on workers’ experience accumulation, which often causes assembly errors and omissions, affects product quality, and lacks a stable guarantee; and workers are prone to fatigue after working for a long time, resulting in a decrease in work efficiency
