[0002] Electronic countermeasure antennas are mainly used to receive and transmit electromagnetic waves and are an important part of radio systems. When installing the antenna, it is necessary to first fix the antenna on the antenna bracket, and then install the antenna bracket on the aircraft. During the installation of the bracket and the aircraft, it is necessary to accurately drill holes on the two mounting surfaces of the bracket to ensure that the bracket and the aircraft are reliably assembled. The existing technology includes the following two hole drilling methods: manual marking and positioning, and "returning holes" using the existing hole positions of the original bracket. The above-mentioned existing technology has the following disadvantages: 1. Manual marking and positioning is time-consuming and labor-intensive, with large errors, and requires a high level of technical skills from the construction workers; 2. Using the existing hole positions of the original bracket for "returning holes", during the marking process, due to the small fitting area of ​​the mounting surfaces of the two brackets, it is difficult to ensure that the two brackets are stable, flush and fitted without movement and shaking during the marking and positioning process, that is, it is impossible to ensure that the two brackets are accurately fitted, which ultimately results in large positioning errors.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] In conventional technology, the antenna bracket 2 includes a second horizontal section 23, a third inclined section 21, and a fourth inclined section 25. The third and fourth inclined sections 21, 25 are arranged at an angle at either end of the second horizontal section 23 along its length. The second horizontal section 23 is provided with a cable through-hole 22. Mounting the antenna bracket 2 on an aircraft requires openings in the third and fourth inclined sections 21, 25. Below the second horizontal section 23 is a mounting section 24 for mounting the antenna.

[0031] The utility model provides a hole-positioning fixture 1 for an electronic countermeasure antenna bracket, comprising a first horizontal section 12, a first inclined section 13, and a second inclined section 19. The first and second inclined sections 13, 19 are obliquely arranged at opposite ends of the first horizontal section 12 along its length. The first horizontal section 12 is provided with a positioning protrusion 16, which is equipped with a positioning clip 15. The positioning clip 15 can extend or retract radially from the positioning protrusion 16. The positioning protrusion 16 can be inserted into a cable through-hole 22 of an antenna bracket 2, so that the end faces of the second horizontal section 23 along its thickness direction align with the first horizontal section 12 and the positioning clip 15, respectively. The first inclined section 13 aligns with the third inclined end of the antenna bracket 2, and the second inclined end aligns with the fourth inclined end of the antenna bracket 2. Specifically, the first horizontal section 12 and the first inclined section 13 form a first obtuse angle. The first horizontal section 12 and the second inclined section 19 form a second obtuse angle. The second horizontal section 23 and the third inclined section 21 form a third obtuse angle. The second horizontal section 23 and the fourth inclined section 25 are arranged at a fourth obtuse angle. The first obtuse angle is equal to the third obtuse angle, ensuring that the first inclined section 13 can accurately fit with the third inclined section 21. The second obtuse angle is equal to the fourth obtuse angle, ensuring that the second inclined section 19 can accurately fit with the fourth inclined section 25. This ensures that the positioning tool and the antenna bracket 2 are accurately matched, and the first positioning hole 14 and the second positioning hole 20 can accurately locate the opening position on the antenna bracket 2.

[0032] When positioning protrusion 16 passes through cable through-hole 22, positioning clip 15 retracts into positioning protrusion 16 under the action of the inner wall of cable through-hole 22. When positioning clip 15 is released from cable through-hole 22, it extends from positioning protrusion 16, and the upper positioning surface of positioning clip 15 aligns with the lower positioning surface of the second horizontal section 23 of antenna bracket 2. First slanted section 13 is provided with a first positioning hole 14 extending through the thickness direction. First positioning hole 14 is used to locate the opening position on the surface of third slanted section 21 of antenna bracket 2. Second slanted section 19 is provided with a second positioning hole 20 extending through the thickness direction. Second positioning hole 20 is used to locate the opening position on the surface of fourth slanted section 25 of antenna bracket 2.

[0033] The electronic countermeasure antenna bracket hole positioning tool 1 also includes a first positioning pin, which is inserted into the first positioning hole 14, and the end of the first positioning pin that contacts the antenna bracket 2 is a conical structure, and the tip of the conical structure, the central axis of the positioning member, and the central axis of the first positioning hole 14 are collinear. The first positioning hole 14 is formed with an internal thread, and the first positioning pin is formed with an external thread, and the internal thread and the external thread are threaded together. There are two first positioning holes 14 and two first positioning pins, and the two first positioning holes 14 and the two first positioning pins are arranged in a one-to-one correspondence, and the two first positioning holes 14 are spaced apart along the width direction of the first inclined section 13. Gently rotate the first positioning pin so that the tip of its conical structure squeezes the surface of the third inclined section 21 to leave a dot-shaped depression, thereby completing the positioning of the hole position.

[0034] The electronic countermeasure antenna bracket hole positioning tool 1 also includes a second positioning pin 18, which is inserted into the second positioning hole 20. The structure of the second positioning pin 18 is identical to the first positioning pin: the end of the second positioning pin 18 that contacts the antenna bracket 2 is conical, with the tip of the cone, the center axis of the positioning member, and the center axis of the second positioning hole 20 collinear. There are two second positioning holes 20 and two second positioning pins 18, each corresponding to a one-to-one arrangement. The two second positioning holes 20 are spaced apart along the width of the second inclined section 19. The second positioning pin 18 is gently rotated so that the tip of its cone presses against the surface of the fourth inclined section 25, leaving a dotted depression, thereby completing the positioning of the hole.

[0035] The outer wall of the positioning protrusion 16 is concavely provided with a slide groove, and the positioning clamp 15 is partially slidably arranged in the slide groove. The elastic member is arranged in the slide groove and its two ends are respectively pressed against or fixedly connected to the positioning clamp 15 and the bottom wall of the slide groove. In a specific embodiment, a compression spring is selected as the elastic member.

[0036] Furthermore, a guide edge 17 is provided at the free end of the positioning protrusion 16. The diameter of the guide edge 17 gradually decreases in a direction away from the end face of the positioning protrusion 16, forming an inclined annular transition surface.

[0037] Furthermore, there are multiple positioning clamps 15 , and the multiple positioning clamps 15 are distributed at intervals along the circumference of the positioning protrusion 16 .

[0038] Furthermore, the first horizontal section 12 is also provided with a handle 11 .

[0039] Furthermore, the first horizontal section 12, the first inclined section 13 and the second inclined section 19 are integrally formed.

[0040] Furthermore, the first horizontal section 12 is also provided with a weight-reducing through hole.

[0041] The positioning method using the aforementioned electronic countermeasure antenna bracket hole positioning tool 1 is as follows: the positioning tool's positioning protrusion 16 extends through the bracket's cable through-hole 22 to restrict horizontal positioning. The bottom end surface of the first horizontal section 12 in the thickness direction mates with the upper end surface of the second horizontal section 23 in the thickness direction of the antenna bracket 2. The upper end surface of the positioning clamp 15, serving as a positioning surface, mates with the lower end surface of the second horizontal section 23 in the thickness direction to restrict vertical positioning. After securing, the first positioning pin is rotated so that its tip presses against the third inclined section 21 of the antenna bracket 2, leaving a dotted depression on the surface of the third inclined section 21 as a marking for the hole location. The second positioning pin 18 is rotated so that its tip presses against the fourth inclined section 25 of the antenna bracket 2, leaving a dotted depression on the surface of the fourth inclined section 25 as a marking for the hole location.
