specific Embodiment approach

[0028] When a large-scale radome is tested for electrical performance, since the total weight of the radome, the radome mounting fixture, the antenna and the antenna mounting fixture exceeds the bearing capacity of the rolling ring of the turntable, the structure of the present invention is adopted, and the specific implementation is as follows:

[0029] Install the circular slide rail 5 in the device on the rear end face of the circular turntable 4, first install the long section of the slide rail 5, then evenly distribute the four slide blocks 6 with anti-tipping function on the slide rail 5, and then Install the short section of the slide rail 5, install the mounting ring 7 on the slider 6 with screws to ensure that the four sliders 6 slide synchronously, and then respectively connect the two ends of the U-shaped connecting plate 8 with the rolling ring 3 and the installation with screws. Ring 7 is connected, so far the installation of the device is complete.

Abstract

The invention belongs to the technical field of radome tooling design and particularly relates to a multi-angle adjustment device for electric performance testing of a large radome. In the process ofthe electric performance testing of a phased array radome, the testing posture changes frequently and the time and energy are wasted. The multi-angle adjustment device comprises an annular turntable;a front end of the annular turntable is provided with a rotatable rolling ring; an antenna is mounted on the rolling ring; a circular sliding rail is further mounted on a rear end of the annular turntable; a mounting ring is rotatably mounted on the sliding rail through a slider; two ends of a U-shaped connecting plate are respectively connected with the rolling ring and the mounting ring; one endof a mounting claw is mounted on the mounting ring, and the other end of the mounting claw is connected with the radome after passing through a middle hole of the mounting ring, the circular turntable and the rolling ring. The working procedure that the radome and a clamp thereof need to be dismounted each time the posture is changed is omitted, and the rolling ring and the mounting ring can be controlled to roll synchronously through a computer, thus the manufacturing cost is low, the operation is convenient and the testing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of radome tooling design, and in particular relates to a multi-angle adjustment device for testing the electrical performance of a large radome. Background technique [0002] The electrical performance test of the radome generally needs to test two polarization attitudes of vertical polarization and horizontal polarization. Therefore, the antenna and the radome need to be installed in two polarization attitudes. , if you want to cover all angles, you must remove the radome and antenna, turn 180° and install the test. [0003] For the flat antenna and radome, the antenna is installed on the pole, and the radome is installed on the front ring of the turntable. The radome can rotate freely at various angles, and it is installed and fixed after reaching the attitude. [0004] But for active phased array radar, the antenna needs to be mounted on the rolling ring at the front end of the turntable. The small rado...
