Description
Technical field
The utility model relates to a kind of pick-up unit, particularly the pick-up unit of high-accuracy friction pair fitness.
Background technology
Friction pair is the mechanical component of widespread use in modern machines, and the work of this element is that two objects contacted produce relative sliding.
The application that friction pair is existing certain on clinical medicine, as the native articular cartilage, prosthese etc. made with spherical friction pair.The condition of work of friction pair is very complicated, when lubricating condition is good, friction condition between the rotating ring of friction pair and stationary ring surface of contact have impact on life-span and the work quality of friction pair, and the surface profile of friction pair affects its contact condition and friction behavior, therefore the machining precision of friction pair, quality of fit require high.
Friction pair needs after having produced to carry out a series of quality testing, fitness for friction pair detects, current modal method is that workman detects its mated condition by rule of thumb, and this type of detection method is simple, quick, but is not suitable for the inspection of high precision friction pair fitness.Existing detection technique also has vibration detection, Acoustic detection etc., but easily introduces external interference factor in test, can not reflect the real features of friction pair, therefore, do not have all the time at present a kind of precision high, test perfect measuring method and device.
Utility model content
Problems existing in detecting for friction pair fitness, the friction pair fitness pick-up unit that the utility model provides a kind of precision high, effective.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of device for detecting high-accuracy friction pair fitness, comprises tank body, microphone, mounting platform, shock insulation pedestal, drive motor.
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 high-accuracy friction pair.
Described high-accuracy friction pair comprises the first joint and second joint, and described first joint is arranged on mounting platform by hinge, and described second joint connects cam, and described second joint is flexibly connected with between cam, and described cam is driven by the outer drive motor of tank body.
Described microphone is arranged in tank body by metal hose, and described microphone has many groups and position adjustable and direction.
The inwall coating acoustical material of described tank body.
High pressure, high density gas is filled in described tank body.
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 the utility model, high-accuracy friction pair relative sliding in tank body is driven by the outer drive motor of tank body, be provided with in tank body and organize microphone more, measured the audio frequency change in high-accuracy friction pair motion process by microphone, thus obtain the situation such as fitness, clearance evenness degree of high-accuracy friction pair.
The utility model compared with the existing technology has the following advantages and effect: 1, install in tank body and organize microphone more, effectively can obtain the noise information of high-accuracy friction pair, changed by audio frequency, can the situation such as fitness, clearance evenness degree of friction pair under each characteristic frequency of express-analysis noise.2, be placed on outside tank by drive motor, high-accuracy friction pair is arranged in tank, utilizing the sealing of tank body by not belonging to the Noise insulati on of high-accuracy friction pair generation, reducing the impact of environmental noise simultaneously, improve measuring accuracy.3, tank interior is coated with acoustical material, can prevent reverberation.5, fill the high density gas such as high pressure, carbon dioxide in tank body, strengthen the transmission of sound.6, the mounting platform placing high precision friction pair is fixed on shock insulation ground through tank body, can prevents the collision of the collision between high precision friction pair and platform and platform and tank body from causing new noise.7, microphone is arranged on tank body by metal hose, and arbitrarily can adjust position and the direction of microphone, be convenient for measuring, flexibility ratio is good.8, tank body comprises can body and cover, and high-accuracy friction pair to be measured is easy for installation.
