Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] figure 1 It is an assembly diagram of the piston-type high-frequency air pressure sensor detection system. It can be seen from the figure that the system is mainly composed of the base 2, the numerical control display system 35, the motor-speed increaser assembly 34, the piston-connecting rod-cylinder assembly 33, the opening width The control assembly 32 and the sensor assembly 31 are composed of parts.

[0022] The numerical control display system is used to display various parameter information such as the current system operating status and pressure frequency, and is responsible for the overall control of the system. The motor-gearbox assembly is used to adjust the movement speed of the piston, which is the power source for generating the test air pressure frequency, and different test frequency requirements can be realized by adjusting the speed ...

Abstract

The invention discloses a piston type medium-frequency air pressure sensor detection device which comprises a base, a cylinder barrel, a cylinder, a second connecting rod and a driving mechanism. A piston is arranged in one side of the cylinder barrel; the end part of the piston can move along the front-back direction of the cylinder barrel under the action of the driving mechanism; a first hingepoint and a second hinge point are arranged outside the other side of the cylinder barrel; one end of the cylinder is hinged to the second hinge point; the second connecting rod comprises a blade connecting strut and a cylinder connecting strut; the end of the blade connecting strut is hinged to the first hinge point, the blade connecting strut is arc-shaped, arc-shaped blades are fixedly arrangedon the arc-shaped inner side of the blade connecting strut, the arc-shaped outer side of the blade connecting strut is fixedly connected with one end of the cylinder connecting strut, and the other end of the cylinder is hinged to the other end of the cylinder connecting strut. The measurement precision of the intermediate-frequency air pressure sensor can be measured and calibrated quickly and accurately, the detection of different types of medium-frequency air pressure sensors can be satisfied, and the effective measurement range of the sensor can be verified.

Description

technical field [0001] The invention discloses a detection device, in particular to a detection device of an intermediate frequency air pressure sensor. Background technique [0002] High-frequency air pressure sensors are commonly used in high-speed operation and high-speed flight equipment. They are mainly used to measure the fluctuation frequency of gas pressure waves. According to the frequency value, the current working conditions of the equipment, external loads, etc. are judged. Due to the vibration of the equipment under the action of external excitation, for example, when the aircraft is flying at high speed, the wing will flutter under the excitation of some external eddy currents, etc., and the machine tool will generate vibration during high-speed rotating cutting. Detection is usually detected by an acceleration sensor. [0003] However, in some practical applications, such as aircraft and other aircraft, it is more effective and faster to use the frequency of ...
