In the process of use, the base is connected with a high temperature vibration member to be tested in a welding manner or other manners; the vibration sensor is fixed on the top cover, and the cooling component is used for cooling the top cover in real time, thereby lowering the temperature of the vibration sensor on the top cover, and ensuring the temperature of the vibration sensor not to exceed an allowable range; and the base is rigidly connected with the top cover, thereby ensuring the test accuracy of the vibration sensor.
Description
Technical field
The utility model belongs to automobile engine exhaust system vibration-testing field, specially refers to a kind of stationary installation of the vibration transducer for vibrating under the test condition of high temperature.
Background technology
Vibration is the important design parameter of modern various engineerings, therefore need manufacture and design the vibration transducer (being acceleration transducer) of various requirement, with accurate test structure vibration.At present the working temperature of the vibration transducer of test vibration commonly used generally is lower than 120 ℃, the highlyest is no more than 260 ℃; Yet the temperature of many engineering parts is higher than 260 ℃ far away, even reach 1000 ℃, therefore vibration transducer commonly used can't meet the demands, must use the vibration transducer of anti-higher temperature, and high temperature resistant vibration transducer all is tens times even hundred times of common vibration transducer on technology or cost, has greatly improved testing cost.
Summary of the invention
The purpose of this utility model is the stationary installation that proposes a kind of vibration transducer, can substitute resistant to elevated temperatures vibration transducer with common vibration transducer in the high-temperature vibrating test, thereby reduces testing cost.
The stationary installation of vibration transducer of the present utility model comprises the base that is connected for UUT, and be used for the fixedly top cover of vibration transducer, key is that described base and top cover are rigidly connected, and described top cover is close to and is provided with the cooling-part that can implement to top cover cooling.
In use, base is connected on the high-temperature vibrating spare to be measured by welding or other modes, vibration transducer is fixed on the top cover, by cooling-part top cover is cooled off in real time, can reduce the temperature of the vibration transducer on the top cover, thereby the temperature that guarantees vibration transducer is no more than its tolerance band.And base and top cover are rigidly connected, and can guarantee the accuracy of vibration transducer test.
Further, be the heat transmission between isolated base and the top cover, the temperature of top cover can be remained in the suitable scope, described cooling-part is located between base and the top cover.
Further, described cooling-part is the cylindrical shell of top and bottom end opening, and described cylindrical shell cooperates to form a hollow cavity body structure with top cover, base, and a side of described cylindrical shell is provided with water inlet, and opposite side is provided with water delivering orifice.By in the hollow cavity body structure, pumping into mobile chilled water, the heat of base and top cover can be taken away rapidly, thereby the temperature of reduction top cover guarantees that the temperature of the vibration transducer on the top cover is no more than its tolerance band.
Further, install for convenient, described base, top cover are connected with cylindrical shell by threaded engagement respectively.
The fixture structure of vibration transducer of the present utility model is simple, cheap, easy to use, can utilize common vibration transducer just can test the vibration of high temperature spare by it, improve the serviceability temperature scope of common vibration transducer, reduced testing cost.

Fig. 1 is the structural representation of the stationary installation of vibration transducer of the present utility model.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the stationary installation of the vibration transducer of the present embodiment comprises for the base 1 that is connected with UUT, and be used for the fixedly top cover 2 of vibration transducer, base 1 is rigidly connected with the cylindrical shell 3 of top cover 2 by a top and bottom end opening, cylindrical shell 3 cooperates to form a hollow cavity body structure with top cover 2, base 1, one side of cylindrical shell 3 is provided with water inlet 4, and opposite side is provided with water delivering orifice 5.
Install for convenient, base 1, top cover 2 are connected with cylindrical shell 3 by threaded engagement respectively.
In use, base 1 is connected on the high-temperature vibrating spare to be measured by welding or other modes, vibration transducer is fixed on the top cover 2, in the hollow cavity body structure, pump into mobile chilled water, the pressure differential of control water inlet and water outlet is regulated the chilled water flow velocity, and then the heat absorption efficiency of adjusting chilled water, the heat of base 1 and top cover 2 can be taken away rapidly, thereby reduce the temperature of top cover 2, the temperature that guarantees the vibration transducer on the top cover 2 is no more than its tolerance band, and base 1 and top cover 2 are rigidly connected, and can guarantee the accuracy of vibration transducer test.
