Of course, in the embodiment of the present invention, the testing apparatus further includes a servo encoder 200 for frequency modulation of the power unit 4, and a battery module 300 for providing power to the power unit 4, wherein the servo encoder 200 is electrically connected to the power unit 4, and the battery module 300 is electrically connected to the power unit 4. Through servo encoder 200, can be to the frequency of power portion 4 is adjusted, so that the rotational frequency of power portion 4 is adjustable, in order to adapt to all kinds of to be tested in the apparatus gyroscope, strengthens the commonality of test equipment.

In the embodiment of the invention, the testing device limits the position of the product to be tested through the jig part 1 and is arranged on the mounting part 2, and the power part 4 and the transmission part 3 drive the mounting part 2 and the jig part 1 to repeatedly rotate in the positive direction and the negative direction by taking the central line of the jig part 1 as a rotating shaft, so that repeated positive and negative horizontal rotating forces are applied to the gyroscopes of a plurality of products to be tested, and the stability of the horizontal planes of the gyroscopes of the products to be tested is ensured. The technical scheme provided by the embodiment of the invention can test a plurality of products simultaneously, and the rotation direction of the test can be switched in the test process, thereby being beneficial to improving the test efficiency.

It will be appreciated that the test apparatus of the present invention is not limited to use with the stability of the level of the gyroscope in a product. If it is merely the object of changing the test of the test equipment, the protection scope of the present invention should still be included.

Finally, it should be noted that: the above examples are only for illustrating the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. And such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
