Embodiment 1

[0044] The structural layout of a servo mechanism zero lock test device is as follows: figure 1 As shown, it consists of a frame assembly 1, 4 mass block assemblies 4 and 4 mechanical levers 5. The device is loaded by a combination of a mass block assembly and a mechanical lever. The mass block assembly applies a loading force, the mechanical lever amplifies the loading force, and applies the amplified loading force to the servo mechanism. Each mechanical lever is equipped with two installation stations for tension and compression, which can realize the loading transformation of the product in the direction of tension and compression. The whole device has a total of 8 stations, which can test 4 servo mechanisms at the same time.

[0045] The frame assembly 1 is a frame structure welded with channel steel, square steel pipes, square steel plates, etc., and is the body of the test bench. The structural layout of the rack components is as follows figure 2 As shown, it mainly...

Abstract

The present invention relates to a zero-position locking test device and test method for a servo mechanism. The test device comprises a rack assembly, mass block assemblies and mechanical levers; the rack assembly is provided with a bottom plate and a cross beam; 2n test station lower supporting plugs are distributed on the upper surface of the bottom plate; the cross beam is parallel to the bottom plate; the cross beam is provided with n lever supporting plugs; each mass block assembly includes a weight balancing block, a supporting rod and a hanging hook, wherein the weight balancing block is fixed onto one end of the supporting rod, and the hanging hook is arranged at the other end of the supporting rod; n mechanical levers are adopted; each mechanical lever is sequentially provided with a drawing station pin, a fulcrum mounting hole, a compression station pin and a clamping slot; each mechanical lever is connected with a corresponding lever supporting plug through a corresponding fulcrum mounting hole; and the hanging hooks are matched with the clamping slots. According to the zero-position locking test device for the servo mechanism of the invention, the mass block assemblies and the mechanical levers are combined to carry out loading, so that a large loading force for the servo mechanism can be realized; and traditional hydraulic loading can be replaced. The test device is simpler in structure and is good in universality. With the test device adopted, a plurality of servo mechanisms can be tested simultaneously, and therefore, test efficiency is high.

Description

technical field [0001] The invention relates to a zero-position locking test device and a test method of a servo mechanism, belonging to the field of servo systems. Background technique [0002] High thrust rocket motors have an inherent eccentricity at zero. In non-working state, if the servo mechanism cannot reliably lock the zero position, the eccentric torque of the engine will compress the servo mechanism to the limit position, causing the engine swing hose to be under stress for a long time, reducing the reliability of the engine, so the long-term reliable zero position The bit locking function is one of the key technical indicators of this type of servo mechanism. [0003] At present, the zero position locking function of the servo mechanism is tested, and the servo mechanism is generally loaded by hydraulic means, that is, the lug at one end of the servo mechanism is fixed, and the hydraulic cylinder simulates the eccentric torque of the engine to act on the lug at ...
