In this embodiment, the performance detection device for the angular velocity detection element is explained using the angular velocity detection of a gyroscope as an example.

[0033] Embodiment 1:

[0034] Figure 1 It is a structural schematic diagram of a performance detection device of an angular velocity detection element according to an embodiment of the present application; Figure 2 This is a schematic structural diagram from another angle of the performance detection device of the angular velocity detection element described in an embodiment of the present application.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a performance detection device for an angular velocity detection element, including a test rack 10 and a test mechanism 20 and a host computer 30 arranged on the test rack 10 .

[0036] In the embodiment of the present application, the test rack 10 is used to support the test mechanism 20 and the host computer 30 .

[0037] In the embodiment of the present application, the testing mechanism 20 includes a carrier 21 for carrying a plurality of workpieces 101 to be tested and a driving source 22 for driving the carrier 21 to rotate. The driving source 22 is connected to the carrier 21 through a rotating element.

[0038] It should be noted that the workpiece 101 to be detected can be a gyroscope. The drive source 22 is a motor, and the motor is installed on the test rack 10. The output shaft of the motor is in transmission connection with the rotating element. In the working state, the motor drives the rotating element to rotate, thereby driving the carrying platform 21 to rotate. In this embodiment, the rotating element is a rotating shaft, one end of the rotating shaft is in transmission connection with the drive source 22, and the carrying platform 21 is installed at the other end of the rotating shaft. In other embodiments, the drive source 20 can also be an electric motor or various actuators such as engines, turbines, and hydraulic drives.

[0039] In the embodiment of the present application, the host computer 30 is arranged on the test rack 10, and the host computer 30 is connected to each workpiece 101 to be detected through a slip ring connector 40. The host computer 30 can receive the electrical signals sent from the workpiece 101 to be detected.

[0040] It should be noted that when the drive source 22 drives the carrying platform 21 to rotate, the workpiece 101 to be detected will test the angular velocity sensed by itself and transmit the angular velocity to the host computer 30 for display. The carrying platform 21 also has an angular velocity driven by the drive source 22, and this angular velocity is determined by the drive source. If the angular velocity of the drive source 22 is the same as the angular velocity detected by the workpiece 101 to be detected, it indicates that the workpiece 101 to be detected is a qualified product. In order to ensure that the workpiece 101 to be detected can be electrically connected to the host computer 30 under the condition of rotation, the performance detection device of the angular velocity detection element connects the host computer 30 to each workpiece 101 to be detected through the slip ring connector 40, and the host computer 30 can collect the data detected by the workpiece 101 to be detected in real time.

[0041] A performance detection device for an angular velocity detection element provided by the present application includes a test rack, a test mechanism and a host computer arranged on the test rack; the test mechanism includes a carrying platform for carrying a plurality of workpieces to be detected and a drive source for driving the carrying platform to rotate; the host computer is connected to each workpiece to be detected through a slip ring connector. The performance detection device of the angular velocity detection element places the workpiece to be detected on the carrying platform, the drive source drives the carrying platform to rotate to drive the workpiece to be detected to rotate, and the workpiece to be detected transmits the detected angular velocity data to the host computer in real time through the slip ring connector, and determines whether the workpiece to be detected is a qualified product according to whether the detected angular velocity data is consistent with the angular velocity of the drive source rotation, realizing the automatic detection of the workpiece to be detected, improving the detection efficiency of the workpiece to be detected, and solving the technical problems of low detection efficiency and high detection cost in the performance detection of existing gyroscope products.

[0042] Such as Figure 1 and Figure 2As shown, in an embodiment of the present application, the carrier 21 includes at least one first-direction fixture 211 for measuring the first axial direction of the workpiece 101 to be detected and at least one second-direction fixture 212 for measuring the second axial direction of the workpiece 101 to be detected.

[0043] It should be noted that the workpiece 101 to be detected is fixed on the first-direction fixture 211 and / or the second-direction fixture 212 by fasteners. In this embodiment, there is a placement area for the workpiece 101 to be detected on the carrier 21 (such as the first-direction fixture 211 and the second-direction fixture 212). When the workpiece 101 to be detected is placed on the first-direction fixture 211 and / or the second-direction fixture 212, the workpiece 101 to be detected can rotate with the carrier 21, and performance tests can be carried out on multiple workpieces 101 to be detected placed on the carrier 21. Among them, the first-direction fixture 211 can be used as a fixture for measuring the horizontal axial direction of the workpiece 101 to be detected, and the second-direction fixture 212 can be used as a fixture for measuring the vertical axial direction of the workpiece 101 to be detected. The performance detection device of the angular velocity detection element realizes the measurement of the angular velocity of the horizontal axial direction of the workpiece 101 to be detected by being placed on the first-direction fixture 211, and realizes the measurement of the angular velocity of the vertical axial direction of the workpiece 101 to be detected by being placed on the second-direction fixture 212, enabling the performance detection device of the angular velocity detection element to not only measure the angular velocity of one axial direction of the workpiece 101 to be detected, but also measure the angular velocities of multiple axial directions of the workpiece 101 to be detected, making the performance detection device of the angular velocity detection element more practical.

Each connection wire 43 is connected to a workpiece 101 to be detected, and each connection contact 42 is connected to the host computer 30 through a cable 44.

[0046] It should be noted that the workpiece 101 to be detected is electrically connected to the conductive slip ring 41 through the connection wire 43, so that the conductive slip ring 41 rotates together with the carrier 20 and the workpiece 101 to be detected. The conductive slip ring 41 is connected to the host computer 30 through the connection contact 42 and the cable 44, realizing that the host computer 30 can obtain the detected angular velocity data of the workpiece 101 to be detected in real time.

[0047] As Figure 1 shown, in an embodiment of the present application, a through hole 23 is formed in the carrier 20.

[0048] It should be noted that the through hole 23 is a connection hole for connecting the workpiece 101 to be detected with the conductive slip ring 41.

[0049] As Figure 2 shown, in one embodiment of the present application, the host computer 30 includes a host 31 disposed on the test rack 10 and a display screen 32 connected to the host 31.

[0050] It should be noted that the host computer 30 can be a mobile terminal such as a computer or an industrial control computer. In other embodiments, the host computer 30 can be a tablet, a mobile phone, etc.

[0052] As Figure 4 shown, in one embodiment of the present application, a test cover 24 is provided on the carrier table 21.

[0053] It should be noted that in order to ensure the detection quality of the workpiece 101 to be detected and avoid interference from other factors, it is wrapped by the test cover 24 outside the carrier table 21.
