Synthetical stiffness testing device for servo valve armature assembly

Abstract

The invention belongs to the technical field of detecting devices, and particularly relates to a synthetical stiffness testing device for a servo valve armature assembly. The synthetical stiffness testing device comprises a base, a supporting frame, a limiting plate base, a main sliding rod, an auxiliary sliding rod and a top plate, and the supporting frame is fixedly mounted at the bottom of an inner cavity of the base. According to the synthetical stiffness testing device for the servo valve armature assembly, through combined application of accessories, mold plates can be additionally arranged on limiting plates, the mold plates can be matched with metal plates and the limiting plates for mounting and demounting, so that in the testing process of the armature assembly, the mold plates can be replaced according to peripheral sizes of different armature assemblies, flexibility is high, the testing range is wide, the periphery of the armature assembly can be buckled with main grooves and auxiliary grooves in the mold plates, thus a main clamp and an auxiliary clamp are conveniently matched for pulling testing after fixing, the testing effect is stable, testing data are effective, the positions of the limiting plates can be shielded by external additionally arranged sashes, damage caused by splashing of the armature assembly is prevented, and safety is high.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a comprehensive stiffness test device for an armature assembly of a servo valve. Background technique [0002] The servo valve mainly refers to the electro-hydraulic servo valve, which outputs the modulated flow and pressure after receiving the electrical analog signal. It is not only an electro-hydraulic conversion element, but also a power amplification element. It can convert a weak electrical input signal with low power into a high-power hydraulic energy (flow and pressure) output. In the electro-hydraulic servo system, it combines the electrical part with the hydraulic part. Connected to realize electro-hydraulic signal conversion and hydraulic amplification, the electro-hydraulic servo valve is the core of electro-hydraulic servo system control. [0003] Among them, the armature component is the core component of the servo valve, and it is the decisive part that ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a comprehensive rigidity testing device for the armature assembly of a servo valve to solve the existing test method proposed in the above background technology because the specification of the armature assembly is different, the flexibility of the test is poor, the test range is limited, and For armature components with irregular shapes, the lack of effective fixing methods will cause deviations in test data. When the armature components are stressed, parts of inferior armature components will break and cause splashes, which will reduce the safety of the measurement environment.
