Abstract
The invention relates to a two-axial vibration tool for vibration test of an electro-hydraulic servo valve, which is characterized by comprising a mounting bottom plate (1), a first supporting bottom plate (2) and a second supporting bottom plate (3). The mounting bottom plate (1) is connected with the first supporting bottom plate (2) and the second supporting bottom plate (3) together, and the first supporting bottom plate (2) and the second supporting bottom plate (3) are connected together, wherein the mounting bottom plate (1) is directly tapped with a threaded hole corresponding to the electro-hydraulic servo valve, and the first supporting bottom plate (2) and the second supporting bottom plate (3) are processed with grooves for fixing. The invention adopts the vibration tool for the vibration test of the electro-hydraulic servo valve, the tool arranges the electro-hydraulic servo valve onto the mounting bottom plate of the tool, and then the first supporting bottom plate or the second supporting bottom plate is fixed on a vibration test bed to vibrate along with the vibration test bed, so that vibration test can be carried out by multiple components, and reversing is convenient and saves trouble.
Description
Technical field
The present invention is used for the electrohydraulic servo valve vibration test.
Background technology
Electrohydraulic servo valve has experienced 50 years in the development of international professional domain, and the occasion of application also more and more widely.Yet the research of servo-valve and manufacturing also are in a relatively backward state at home, and especially the stability of domestic servo-valve and external advanced electrohydraulic servo valve also exist very big gap under rugged surroundings.Vibration frock as the electrohydraulic servo valve vibration test is to be used for the analog electrical hydraulic servo at following index of stability that can reach of different environment.Therefore the vibration test of electrohydraulic servo valve is particularly important, and a good vibration frock also is indispensable then.
Summary of the invention
For the vibration test of servo-valve, all be single unidirectional operating in the past, implementing like this is the time-consuming gas of also requiring great effort, generation of the present invention solves the above problems, and can a plurality ofly carry out when making vibration test, and feasible commutation is conveniently saved trouble.
For achieving the above object, technical scheme of the present invention is as follows:
The two direction of principal axis vibration frock part that is used for the electrohydraulic servo valve vibration test, it is characterized in that, comprise base plate (1) is installed, supporting baseplate one (2), supporting baseplate two (3), base plate (1) and supporting baseplate one (2), supporting baseplate two (3) are installed to link together, supporting baseplate one (2) and supporting baseplate two (3) link together, the threaded hole of directly attacking corresponding to some extent electrohydraulic servo valve on the base plate (1) wherein is installed, is processed with fixing required groove on supporting baseplate one (2) and the supporting baseplate two (3).
Base plate (1) is installed, supporting baseplate one (2), supporting baseplate two (3) behind surface grinding again through being welded.
Base plate (1) is installed two, two electrohydraulic servo valves can be installed simultaneously carry out two direction of principal axis vibration tests.
Beneficial effect: the present invention has adopted the vibration frock part that is used for the electrohydraulic servo valve vibration test, this frock part is installed in electrohydraulic servo valve on the installation base plate of frock, be fixed on to reach on the vibration table by supporting baseplate one or supporting baseplate two again and follow the purpose that vibration table together vibrates, can a plurality ofly carry out when making vibration test, and feasible commutation is conveniently saved trouble; The installed surface that base plate is installed is polished, keep its smooth finish, installed surface direct contact with the installation base plate under the protection of the plate that do not need protection of servo-valve installed.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the present invention by install base plate 1, supporting baseplate-2 and supporting baseplate 23 behind surface grinding again through being welded, wherein install directly attack on the base plate 1 the threaded hole of corresponding electrohydraulic servo valve, be processed with fixing required groove on supporting baseplate 1 and the supporting baseplate 23.This frock is installed in electrohydraulic servo valve on the installation base plate 1 of frock, is fixed on to reach on the vibration table by supporting baseplate 1 or supporting baseplate 23 again and follows vibration table and together vibrate.
Claims (3)
