Description

Technical Field

[0001] The present invention relates to the technical field of radome testing, and specifically provides a turntable for radome testing. Background Technique

[0002] A radome is a device used to cover and protect an antenna, usually used to improve the performance and durability of the antenna. It can help reduce the impact of environmental factors such as wind, rain, and snow on the antenna, and at the same time avoid interference from stray signals. The material of the radome is usually transparent or translucent to minimize the impact on signal transmission. When a radome is being processed and produced, performance tests need to be carried out, mainly including signal strength tests, frequency response tests, gain tests, environmental tests, and physical property tests. During the test, the radome is positioned and installed on a turntable, and the turntable performs three-axis rotation to simulate the external usage scenario for performance testing of the radome. When the traditional test turntable for radomes is specifically used, manual assistance is still required for positioning and installation. During the three-axis rotation simulation test, manual blanking is required after the test is completed, which is time-consuming and laborious. Moreover, it can only perform three-axis rotation simulation tests and lacks longitudinal movement tests, and there are certain defects in scenario simulation, affecting the comprehensiveness of radome testing.

[0035] Working principle: When in use, control the fifth motor 34 to start and drive the corresponding material guiding roller 32 to rotate, thereby driving the material guiding belt 33 to drive. Place the radome in the placement groove 331, and automatically transport the radome to be detected, and successively transport the radome to be detected below multiple clamping driving members 6. Control the lifting cylinder 311 to start and drive the radome to move upward. The radome is placed between multiple clamping driving members 6, and the upper surface of the radome contacts the lower surface of multiple limiting frames 7 for limiting.

The rotation of the driving wheel 62 drives the transmission gear 64 to rotate synchronously, thereby controlling the transmission rack 65 to drive the mounting seat 71 and the test antenna 72 to move upward synchronously, so that the test antenna 72 is always in the radome, increasing the longitudinal movement scenario simulation test of the radome and improving the comprehensiveness of the radome test; After the detection is completed, reset the radome so that the radome is placed below, and then control the feeding belt 33 to move upward again. The radome is clamped into the placement groove 331 again. Subsequently, control the driving ring plate 531 to rotate in the reverse direction, and cooperate with the plane thread convex to be movably clamped in the plane thread groove. Control the plurality of driving seats 53 to drive the corresponding positioning sliding seats 52 to move away from each other, so as to control the plurality of clamping driving members 6 to move away from each other.
