Embodiment 1

[0043] like Figure 1-Figure 10 As shown, a micro-electromechanical gyroscope test device includes a gyroscope test chassis 1, a first servo motor 2 is arranged on one side of the inner wall of the gyroscope test chassis 1, and the output shaft end of the first servo motor 2 is connected There is a right partition plate 3, and a first outer frame 5 and a second outer frame 6 are symmetrically arranged on one side of the right partition plate 3 with respect to its transverse center line, and one of the first outer frame 5 and the second outer frame 6 is symmetrically arranged. The side is provided with a left partition 21, the outer wall of the left partition 21 is provided with a first rotating shaft 9, and the first rotating shaft 9 is rotatably connected with the through hole opened on the gyroscope test chassis 1, and the second outer frame 6 A second servo motor 7 is installed on one side of the frame, and the output shaft end of the second servo motor 7 is connected with ...

Embodiment 2

[0052] Based on a MEMS gyroscope testing device provided in the first embodiment of the present application, another MEMS gyroscope testing device is proposed in the second embodiment of the present application. The second embodiment is only a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

Embodiment 1

[0053] Based on the first embodiment, the difference between the second embodiment and the first embodiment is that the second embodiment is as follows: Figure 11-Figure 15 .

[0054] The lower surface of the inner cavity of the placing table 4 is provided with a hole 26, and a rectangular ring member 41 is arranged on the inner cavity wall of the placing table 4, and a T-shaped support plate 27 is deposited above the rectangular ring member 41. The structure is such that the top block 39 is driven to rotate by the rotating shaft 36, and then the top block 39 pushes the T-shaped support plate 27 upward, so that the first T-shaped splint 19 and the second T-shaped splint 20 separate the clamped gyroscope, and then During the upward movement of the T-shaped support plate 27, the gyroscope on the T-shaped support plate 27 can be easily taken out.

[0055]The side of the outer wall of the lower rotating shaft 12 away from the belt 15 is sleeved with an adapter belt 29, and the a...

Abstract

The invention relates to the technical field of gyroscopes, in particular to a micro-electro-mechanical gyroscope testing device which comprises a gyroscope testing bottom frame, a first servo motor is arranged on one side of the inner wall of the gyroscope testing bottom frame, and the output shaft end of the first servo motor is connected with a right partition plate. A first outer frame and a second outer frame are symmetrically arranged on one side of the right partition plate about the transverse center line of the right partition plate, a left partition plate is arranged on one side of the first outer frame and one side of the second outer frame, a first rotating shaft is arranged on the outer wall of the left partition plate, and the first rotating shaft is rotationally connected with a through hole formed in the gyroscope testing bottom frame; according to the device, sliding pieces on the two sides of a first T-shaped clamping plate and the two sides of a second T-shaped clamping plate are driven by a lower rotating shaft to move in a sliding rail frame, in this way, a gyroscope placed in a placement table can be conveniently and rapidly extruded and fixed, then the gyroscope is checked, and the detection accuracy of the gyroscope is improved. In this way, the gyroscopes of different sizes can be conveniently detected and fixed.

Description

technical field [0001] The invention relates to the technical field of gyroscopes, in particular to a microelectromechanical gyroscope testing device. Background technique [0002] A gyroscope is an angular motion detection device that uses the momentum and moment-sensitive shell of a high-speed revolving body relative to the inertial space around one or two axes that are orthogonal to the rotation axis. The angular motion detection device made of other principles has the same function. Gyroscope, a modern gyroscope is an instrument that can accurately determine the orientation of a moving object. It is an inertial navigation instrument widely used in modern aviation, navigation, aerospace and defense industries. Its development is very important to a country's industry, The development of national defense and other high-tech is of great strategic significance. The traditional inertial gyroscope mainly refers to the mechanical gyroscope. Due to the restriction of the aspect...
