Technical Field
The invention belongs to the technical field of radar antenna feeders, and relates to a device for adjusting the position of a feed source in an antenna feeder test process.
Background
In the debugging and testing process of the radar antenna system, in order to obtain a better telecommunication performance test result, the feed source position often needs to be adjusted repeatedly. The antenna system is assembled, the actual position of the feed source often deviates from the theoretical design position, and at the moment, an adjusting device capable of realizing multi-degree-of-freedom adjustment is needed, so that the feed source position can be conveniently and rapidly adjusted to achieve the optimal telecommunication performance. The common feed source position adjustment mode is mainly realized by adopting a mode of adding and subtracting gaskets on the basis of a processed feed source bracket, and the mode has several defects: firstly, the gaskets are increased and reduced, namely discontinuous displacement adjustment is carried out, and the adjustment precision depends on the thickness of the gaskets; secondly, the method for increasing and decreasing the gaskets is suitable for small-range position adjustment, and the requirements cannot be met when the feed source position adjustment range is large.
In order to solve the problems, a device for positioning a feed source by means of motor driving is invented in a patent 'feed source positioning and focusing device for compact range measurement', and the device can rapidly position the feed source in a large adjustment range, but has the following defects: 1. the device can position two feed sources at most at the same time, but the positions of the two feed sources cannot be adjusted independently; 2. after the feed source position is determined, the design of subsequent mechanical positioning is not considered, the feed source position is maintained unchanged only by means of motor band-type brake force, and the positioning reliability is low.

The lifting base is provided with a Y-direction guide rail and a rotary hole, and the Y-direction guide rail on the transition plate are matched and installed to form a Y-direction translation mechanism. The rotary slide seat is provided with a rotary shaft and a slope guide rail, the rotary shaft is matched with a rotary hole on the lifting base to form a rotary mechanism around the Y direction, and the tail end of the rotary shaft is provided with a fastener which can fix the axial direction of the rotary shaft. The slope angle of the slope is the offset angle of the reflector antenna. The feed source installing support is an L-shaped structure support, the support is provided with a feed source interface flange surface and a guide rail, and the guide rail is matched with the guide rail of the rotary sliding seat to form a translation mechanism of the offset angle direction of the reflecting surface. The design sequence of the four degrees of freedom is as follows: and from one end of the feed source mounting bracket, the translation along the offset angle direction of the reflecting surface, the rotation around the Y direction, the translation along the Y direction and the translation along the X direction are sequentially carried out. And scale indication is arranged on each moving direction, so that the moving distance relative to the initial point can be intuitively read.
