Drawings
Fig. 1 is a schematic structural diagram of the small-angle antenna positioner of the present invention.
Detailed Description
Referring to fig. 1, the utility model discloses a small-angle antenna positioner, it has connector 4 at the front end, and it connects receiving antenna through preceding connecting hole 5, has connecting seat 9 at the rear end, and it installs on the terminal surface before antenna branch through back connecting hole 1. The rotating disc 10 and the sleeve 2 are of a coaxial integrated structure, the sleeve 2 and the connecting seat 9 are sleeved and can rotate relatively, and the positioning can be achieved through the positioning pin 3. Between the surfaces of the rotary disk 10 opposite to the joining head 4, a pair of high-strength springs 8 are mounted at intervals of 90 ° circumferentially on the upper and right sides. A pair of adjusting bolts are connected to the rotating disc 10 at positions symmetrical to the high-strength spring 8 through threads, and abut against the end face of the connector 4 and are respectively a lower adjusting bolt 7 and a left adjusting bolt 6.
When the direction is changed, the antenna assembling and disassembling surface 4 is pushed to deflect by adjusting the left adjusting bolt 6, and the high-strength spring 8 is arranged on the right side, so that the direction deflection of the connector 4 can be realized only by rotating the left adjusting bolt 6, and the purpose of quickly adjusting the direction of the electric axis of the receiving antenna is achieved. Similarly, when changing every single move, because the upside has installed high strength spring 8, so only need rotatory downside adjusting bolt 7, can realize that connector 4 pitch up or bow down and deflect, reach the directional purpose of quick adjustment receiving antenna electric axis every single move.
Before a certain type of missile radome is subjected to electrical property test, the antenna electrical axis is adjusted by using the device, and the specific measures are as follows:
1) the device is arranged on the front end surface of an antenna support rod through a rear connecting hole 1 shown in figure 1 and is connected with a receiving antenna through a front connecting hole 5 of a connector 4; the polarization adjustment of the antenna is realized by rotating the sleeve 2, and the polarization position of the antenna is fixed by the positioning pin 3 after the rotation is in place.
2) After the antenna is fixed, the direction of the electric axis of the receiving antenna is adjusted, if the left deflection of the electric axis is found, the left adjusting bolt 6 is only needed to be screwed, and the electric axis is pushed to deflect rightwards; if the electric axis is deflected rightwards, the antenna is pushed to deflect leftwards by the elasticity of the high-strength spring 8 on the right side only by loosening the adjusting bolt 6 on the left side;
after the azimuth direction of the electric shaft is adjusted to the position, the pitching direction of the electric shaft is adjusted, if the electric shaft is found to deflect downwards, the lower adjusting bolt 7 is only needed to be screwed, and the electric shaft is pushed to deflect upwards; if the electric axis is found to be deflected downwards, the lower adjusting bolt 7 is only required to be unscrewed, the antenna is pushed to deflect downwards by relying on the elasticity of the upper high-strength spring 8, and finally the electric axis alignment of the transmitting and receiving antenna is realized.
