Description

Technical Field

[0001] This utility model relates to the field of RCS testing, specifically to a rotating platform for multi-angle RCS testing. Background Technology

[0002] In the field of radar cross section (RCS) testing technology, with the rapid development of modern stealth technology, radar detection technology and electromagnetic compatibility technology, accurate measurement of the electromagnetic scattering characteristics of target objects at different azimuth and elevation angles has become a key link in radar system design, stealth performance evaluation and electromagnetic interference analysis. RCS testing requires the use of a testing platform.

[0003] The existing RCS testing platform still has the following problems when in use:

[0004] Existing RCS testing platforms are difficult to flexibly adjust the RCS tester at multiple angles. When testing different azimuth and pitch angles, the operation is complicated, time-consuming, and affects testing efficiency. Existing technical testers often need to manually adjust multiple components, and the adjustment accuracy is difficult to guarantee, resulting in a cumbersome testing process and the inability to quickly obtain test data at different angles.

[0005] Furthermore, existing RCS testers are usually fixed with bolts, which requires tools when installing and disassembling, making operation inconvenient. Repeated disassembly and assembly can easily cause the bolt threads to strip, affecting the fixing effect.

[0006] Therefore, we have made improvements to this by proposing a rotating platform for multi-angle RCS testing. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a rotating platform for multi-angle RCS testing, solving the problems mentioned in the background section.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0012] The rotating mechanism includes a rotating block, which is rotatably connected inside the fixed box. The fixed frame is fixedly installed on the upper surface of the rotating block, and a worm gear is fixedly installed on the outside of the rotating block. A worm is meshed with one side of the worm gear.

[0013] As a preferred technical solution of this application, a mounting bracket is fixedly installed on one inner wall of the fixing box, and the worm gear is rotatably connected inside the mounting bracket. A motor is fixedly installed on one side surface of the mounting bracket, and the output end of the motor is fixedly connected to one end of the worm gear.

[0014] As a preferred technical solution of this application, the installation mechanism includes a connecting block, and the connecting block is fixedly installed on the lower surface of the RCS tester. An installation block is fixedly installed on the lower end surface of the connecting block, and the connection between the installation block and the fixed frame is a snap-fit ​​connection.

[0015] As a preferred technical solution of this application, grooves are provided on both sides of the fixing frame, and a locking block is slidably connected inside the groove. The mounting block has slots on both sides, and the locking block engages with the slot.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the scheme of this application:

[0021] 1. By using the rotating mechanism, the motor drives the transmission component to rotate, which in turn drives the connected rotating component to rotate within the fixed structure. This allows the frame on which the RCS tester is mounted to be adjusted at multiple angles. Testers only need to control the forward and reverse rotation of the motor to quickly and accurately adjust the test angle without having to manually adjust multiple components. This greatly simplifies the operation process, saves time, and significantly improves test efficiency, enabling the rapid acquisition of test data at different azimuth and pitch angles.

[0022] 2. Through the use of the installation mechanism, the installation component and the fixed frame are connected by a snap-fit. The limiting structure inside the fixed frame engages with the limiting groove on the lower surface of the installation component. This allows for installation and disassembly without the need for tools, making the operation convenient and quick. It avoids the problem of bolt stripping caused by repeated disassembly and assembly, effectively improves the fixing effect, ensures the stability of the RCS tester during the testing process, and ensures the accuracy of the test data.

[0052] In this embodiment, four limiting blocks 809 are fixedly installed inside the fixed frame 5 on the upper surface of the rotating block 601. A limiting groove 810 is formed on the lower surface of the mounting block 802, and the limiting blocks 809 and the limiting groove 810 are connected by a snap-fit ​​mechanism.

This gives the mounting plate 3 greater freedom of movement. When the hydraulic rod 2 extends or retracts, the height of the mounting plate 3 can be changed. At the same time, since the ball joint 9 can rotate within the fixing blocks 10, the mounting plate 3 and its mounting box 4, mounting frame 5, and RCS tester 7 can be flexibly adjusted in tilt angle.
