The invention discloses a small strong-electromagnetic-radiation-resistant precision rotation device. The bottom of a rotation table surface of the precision rotation device is provided with a lower surface groove, a large conductive sealing ring is arranged in the lower surface groove, the large conductive sealing ring is compressed and sealed through a large sealing cover, a small conductive sealing ring is arranged in a sealing groove of the large conductive sealing ring, the small conductive sealing ring is compressed and sealed through a small sealing cover, and the small conductive sealing ring and a fixed shaft are in sealing contact. The beneficial effects of the device are that the rotation table surface, the large sealing cover, the small sealing cover, the two sealing rings andthe fixed shaft form a sealed conductive cavity so that a defense effect is achieved for strong electromagnetic pulses, normal operation of electromagnetic-sensitive components including an internal motor and a controller can be protected, and small detected members are supported to perform rotary motion in a strong electromagnetic environment; besides, the structure of the rotation device is light so that the device can be conveniently moved in a laboratory, and the test flexibility is improved.
Description
technical field [0001] The invention relates to a precision rotating device, in particular to a small precision rotating device resistant to strong electromagnetic radiation. Background technique [0002] With the development of science and technology, electronic products are becoming more and more abundant. Radiation resistance of electronic devices is one of its important indicators. The anti-radiation ability of electronic devices is usually tested in the electromagnetic compatibility experiment. During the test, the device under test needs to rotate. The existing turntable cannot work normally under the strong electromagnetic pulse field. The conventional EMC turntable has large volume and high power consumption. Small device testing is inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to provide a small precision rotating device resistant to strong electromagnetic radiation, which can effectively prevent strong electroma...
