Abstract
The invention relates to a testing device, in particular to a guide rail match degree testing device in a high-pressure environment. The testing device comprises a tank, microphones, an installing platform, a shock isolating base and a drive device. The installing platform is located in the tank, penetrates through the tank and is fixedly installed on the shock isolating base outside the tank. A linear guide rail is installed on the installing platform. The linear guide rail comprises a guide rail and a sliding block. The drive device is installed outside the tank, penetrates through the tank and is connected with the sliding block. The microphones are at least two in number and are fixedly installed on the sliding block. The inner wall of the tank is coated with a sound absorbing material and filled with high-pressure and high-density gas. According to the testing device, the drive device pulls the sliding block to move on the guide rail, audio information in the moving process of the sliding block is recorded through the microphones, the match condition of the linear guide rail is obtained by means of audio changes, and the guide rail is located accurately.
Description
Technical field
The present invention relates to a kind of verifying attachment, particularly a kind of guide rail fitness verifying attachment.
Background technology
Along with the progress of science and technology, equipment manufacture is to high precision and maximization future development, and links is kept on improving, therefore in order to acquired can better product, the accuracy requirement to mechanical parts such as guide rails must be improved.
The range of application of guide rail is extremely wide, as essential at elevator, lathe middle guide, if phenomenons such as guide rail occurs not steadily in production, assembling, use procedure, vibrations, impact greatly can be produced to its mechanical property, eliminate not in time, just easily produce all kinds of fault, bring potential safety hazard, as when guide rail vibration reaches largely in elevator, also security incident can be caused.
Existing guide rail can carry out the detection of the performance index such as linearity when dispatching from the factory, as utilized electronic theodolite and spirit-leveling instrument to detect the depth of parallelism of guide rail, but this type of measuring method cannot meet more high-precision requirement, and the fitness of guide rail is all generally workman's manual test, the reasonable measuring method of neither one and device all the time at present.
Summary of the invention
For the problem that existing guide rail fitness verifying attachment precision comparison is low, the invention provides a kind of based on acoustical holography technology of marching into the arena, guide rail fitness verifying attachment that measuring accuracy is high, easy to use.
The present invention solves the problems of the technologies described above adopted technical scheme: the guide rail fitness verifying attachment under a kind of hyperbaric environment, comprises tank body, microphone, mounting platform, shock insulation pedestal, drive unit.
Described mounting platform is positioned at tank body, and described mounting platform is fixedly mounted on the shock insulation pedestal outside tank body through tank body, and described mounting platform installs line slideway.
Described line slideway comprises guide rail and slide block, and described drive unit is arranged on outside tank body, and described drive unit is through tank body connection sliding block.
Described microphone has two at least and is fixedly mounted on slide block.
The inwall coating acoustical material of described tank body.
High pressure, high density gas is filled in described tank body.
Further, described drive unit comprises motor, serving, and described slide block two ends connect the outer motor of tank body respectively by serving.
Further, described tank body is provided with view window.
Further, described tank body is made up of can body and cover, and described can body is cylindric, and described cover has two and is arranged on the two ends of can body.
Further, filling CO 2 in described tank body.
In skid process, voice data measured by microphone, by the change of audio frequency, obtain the information of line slideway fitness, and utilize acoustics inverse operation, noise source three dimensions is expressed by holography, in conjunction with noisy matching, can the mated condition of line slideway under each characteristic frequency of express-analysis noise, and accurately locate.
The present invention compared with the existing technology has the following advantages and effect: 1, be placed on outside tank by drive unit, guide rails assembling is in tank, utilizing the sealing of tank body by not belonging to the Noise insulati on of air-bearing generation, reducing the impact of environmental noise simultaneously, improve measuring accuracy.2, on slide block, microphone is organized in installation more, and microphone moves with slide block, effectively can obtain the noise information of to be measured, location noise source.3, tank interior is coated with acoustical material, can prevent reverberation.4, fill the high density gas such as high pressure, carbon dioxide in tank body, strengthen the transmission of sound.5, the mounting platform placing line slideway is fixed on shock insulation ground through tank body, can prevents the collision of the collision between line slideway and platform and platform and tank body from causing new noise.6, tank body comprises can body and cover, makes guide rails assembling convenient.
