Quartz tuning fork gyroscope gauge outfit screening and testing device

Abstract

The invention discloses a quartz tuning fork gyroscope gauge outfit screening and testing device, which comprises a tool shell structure (2), a gauge outfit installation support (12), a measurement and control circuit (4), a vibration reduction assembly, a locking assembly, a round hole socket and a flexible metal belt. The quartz tuning fork gyroscope gauge outfit (1) is installed on the gauge outfit installation support (12) through the locking assembly, and the gauge outfit installation support (12) is in signal connection with a power supply of the measurement and control circuit (4) through a metal belt (6). The gauge outfit installation support (12) is fixedly connected with the tool shell structure (2) through the vibration reduction assembly. A hole is formed in the position, corresponding to the gauge outfit outer lead, of the meter head installation support (12), a round hole socket is arranged in the hole, the gauge outfit lead is inserted into the round hole socket, and thelead end of the round hole socket is connected with the measurement and control circuit (4) through a flexible metal belt. The device is used for screening the quartz tuning fork gyroscope gauge outfit, interference errors of testing are effectively restrained, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tuning fork sensor testing, in particular to a device for screening and testing quartz tuning fork gyroscope heads. Background technique [0002] The head of the quartz tuning fork gyro (tuning fork sensor) is the sensitive element and core device of the quartz tuning fork gyroscope. It forms an independent sensor component after micro-addition and packaging of the sensitive structure. Test to obtain the performance of the meter head, and carry out the performance classification of the meter head, as the basis for matching gyroscopes with different performance levels. During the meter screening test process, due to the weak signal of the meter head and the characteristics of being susceptible to interference, the screening test tooling needs to meet the needs of weak signal detection, and at the same time, meet the needs of batch testing and solve the needs of quick installation and disassembly of the met...

Problems solved by technology

However, the difference between the crystal oscillator and the quartz tuning fork gyro head, such as the output signal form is inconsistent, the output of the crystal oscillator is a frequency signal, and the final output of the gyro head is an angular velocity signal; the sensitivity to external disturbances and other differences, the screening of the gyro head directly refers to the crystal oscillator The industry's screening test devices cannot properly evaluate its performance
