Reference is made to FIGS. 1 to 2, where FIG. 1 is a cross-sectional view of a testing device in an embodiment of the present invention, and FIG. 2 is an enlarged view of a structure of part A in FIG. 1.

The test device is used to test the stability of the gyroscope horizontal surface in the product to be tested, and includes: a jig part 1, an installation part 2, a transmission part 3, and a power part 4.

The jig part 1 is mounted on the mounting part 2 and is used to define the position of one or more products to be tested; one end of the transmission part 3 is fixed to the mounting part 2, and the other end thereof is connected to the mounting part 2. The power section 4 is drivingly connected; the power section 4 is used to drive the transmission section 3 and the mounting section 2 to rotate forward or reverse with the center line of the jig section 1 as a rotation axis, so that The jig part 1 on the mounting part 2 rotates forward or backward with the center line as a rotation axis to test the horizontal level of the gyroscope in one or more products to be tested in the jig part 1. Smoothness.

One or more products to be tested can be placed in the jig unit 1, and each of the products to be tested is coaxially arranged, coincides with the center line of the jig unit 1, and is driven by the power unit 4. The transmission unit 3 is described so that the magnitude and direction of the horizontal rotation force applied by the power unit 4 to each product to be tested are the same to ensure the accuracy of the test.

When the power part 4 drives the transmission part 3 and the mounting part 2 to rotate with the center line of the jig part 1 as a rotation axis, the power part 4 can perform forward rotation and reverse rotation Specifically, when the power part 4 drives the transmission part 3 and the mounting part 2 to rotate forward to a certain angle with the center line of the jig part 1 as a rotation axis, the power part 4 Switch to reverse rotation, and the power section 4 also rotates in the same direction in the reverse direction. After that, the power section 4 switches to the same angle in forward rotation, and so on to test the placement in the jig section 1. The smoothness of the horizontal plane of the gyroscope in one or more products under test. In this embodiment, the angle of forward or reverse rotation of the power unit 4 is 270 °, but in some embodiments, the angle of forward or reverse rotation of the power unit 4 may also be based on specific requirements. The setting is not limited in the present invention.
