The application discloses a position and attitude adjusting mechanism and a position and attitude adjusting method for antenna tests, aiming at addressing the overlapping precision between the centeraxis of a self-spinning disk of a turntable and the center axis of an antenna on a reflection surface. The position and attitude adjusting mechanism includes a rotation part, a translation part, a first connection structure, a second connection structure, an X-axis translation apparatus and a Y-axis translation apparatus. The method includes the following steps: adjusting the X-axis and the Y-axisof a laser source to perform rotation and translation, such that laser light leaves smallest track which serves as a reference point; adjusting the installation surface of an antenna such that the reference point falls to the center pf the antenna; installing a reflector, such that when the self-spinning disk rotates, laser light is reflected by the reflector to the self-spinning disk so as to form a reflection track point; and adjusting the antenna to rotate in the X-axis and Y-axis directions, such that when the self-spinning disk rotates, the reflection leaves smallest track. According tothe invention, the mechanism has the characteristics of simple structure, small size, simplified installation, easy use, and excellent expandability. The method has the characteristics of easiness, excellent universality and wide application.
Description
technical field [0001] The invention belongs to the field of mechanical design, and in particular relates to a position and attitude adjustment mechanism and an adjustment method. Background technique [0002] During the test of the missile radome, the test turntable is usually used. During the test, the central axis of the spin plate of the turntable is required to have a high degree of coincidence with the central axis of the reflector antenna in the distance. [0003] In the traditional installation and adjustment method, the rotation accuracy of each axis of the turntable is guaranteed by the manufacturer. The tooling is installed on the spinning disk, and the tooling and the notch of the spinning disk are used for positioning, and then the laser source is installed on the tooling and the laser point is used to directly align the antenna position. The disadvantage of the method is that the coaxiality of the laser source and the spin axis of the turntable cannot be guaran...
