Description

A single-person mounting fixture and mounting method for microstrip antennas for conical products Technical Field

[0001] This invention belongs to the field of aerospace product testing, specifically relating to a single-person installation method and tooling for a microstrip antenna used for transmitting and receiving signals on a conical product. Background Technology

[0002] The radio altimeter microstrip antenna is a key component of aerospace products, crucial for transmitting and receiving analog signals. The design of its mounting fixture directly impacts testing accuracy and reliability. Existing mounting fixtures for radio altimeter microstrip antennas typically use two nylon straps for binding and securing. The installation process requires two operators: one uses locating pins on the fixture to find the precise position and apply continuous pressure to ensure stability; the other tightens the nylon straps to secure the altimeter. However, this traditional two-person installation method suffers from significant drawbacks, including low efficiency, high labor costs, and insecure fixing.

[0003] Furthermore, in practical applications, existing installation fixtures using nylon straps for binding on conical products are prone to loosening. This is because the contact area between the nylon strap and the conical surface is small, and manual operation results in insufficient and inconsistent fixing force, failing to guarantee a stable installation. Since microstrip antennas require strict fixing conditions to ensure accurate transmission and reception of electromagnetic signals, any loosening caused by insecure installation will lead to electromagnetic signal leakage, test data deviation, and ultimately, the failure of the entire testing process.

[0004] Therefore, there is an urgent need for a new type of installation tool and corresponding installation method that can be operated by a single person to overcome the many shortcomings of existing technologies. This would not only improve installation efficiency and convenience but also effectively avoid testing problems caused by insecure fixing, providing a more reliable guarantee for the testing of radio altimeters. Summary of the Invention

[0005] This invention designs a mounting fixture and method for a conical product radio altimeter microstrip antenna that can be installed by a single person, in order to solve the problems of low efficiency and insufficient reliability of existing fixtures and methods.

[0006] The present invention is achieved by the following technical solution: a single-person installation fixture for a microstrip antenna for a conical product, comprising: a fixture main block 1, an elastic strap 4 fixedly connected to one side of the fixture main block 1, a non-elastic strap 3 fixedly connected to each side of the elastic strap 4, a buckle 10 cooperating with the elastic strap 4 and a ratchet tensioner 9 cooperating with the non-elastic strap 3 fixedly connected to the other side of the fixture main block 1, a wave-absorbing sponge 7 fixedly fixed on the surface of the fixture main block 1, and a signal line interface 12 provided on the fixture main block 1, which is respectively connected to the microstrip antenna 6 and the signal simulator.

[0007] The installation method using the aforementioned fixture includes the following steps: 1) First, connect the signal line of the signal simulator through the signal line interface of the fixture, then connect the elastic strap 4 to its buckle 10 to ensure sufficient tension after the fixture is fitted in. Then connect the two non-elastic straps 3 and 5, and the ratchet tensioners 9 and 11, leaving sufficient space; 2) Fit the fixture onto the surface of the conical product, and use the tension of the elastic strap to initially fix the fixture in place. Then adjust the length of the non-elastic straps, but keep them loose; 3) Align the fixture with the product surface according to the positioning pins 2 and 8, and then press the fixture firmly with one hand until the wave-absorbing surface 7 can no longer be compressed; 4) Keep the fixture pressed with one hand, and tighten the ratchet tensioners 11 and 9 with the other hand until the fixture is stably fixed on the product surface.

[0008] The beneficial effects of the present invention are: (1) The tooling can be installed by a single person, which improves the installation efficiency and reduces the labor cost.

[0009] (2) The tooling uses elastic straps to initially fix the tooling, which reduces the difficulty of connecting the tooling and the product with positioning pins in the later stage and improves the installation efficiency. Attached Figure Description

[0011] This invention relates to a single-person installation fixture and method for fixing a microstrip antenna to a conical aerospace product during radio altimeter testing. The main structure of the fixture is shown in Figures 1 and 2, including: a main fixture block 1; an elastic strap 4 for temporary fixing and a corresponding buckle 10, which provides temporary restraint when the worker connects the fixture to the product using two positioning pins 2 and 8 and tightens the non-elastic strap; two non-elastic straps 3 and 5, and corresponding ratchet tensioners 9 and 11, allowing the worker to apply force with one hand to tighten the non-elastic straps and stably fix the fixture to the product; a wave-absorbing sponge 7 to ensure a tight fit between the fixture and the product, preventing electromagnetic leakage and affecting the radio altimeter test results; a microstrip antenna 6 and a signal line interface 12 for connecting to a signal simulator to transmit and receive analog signals.

[0012] This fixture can be installed by a single person: the worker first uses elastic straps to secure the fixture to the surface of the conical product, which are adjustable. Then, the worker precisely determines the relative position of the fixture and the product using positioning pins. After alignment, the worker can press the fixture onto the product surface with one hand and pull the ratchet tensioner with the other hand to tighten the two non-elastic straps, achieving a tight fit between the fixture and the product. This method allows for single-person installation of the fixture, improving efficiency and reducing costs. Furthermore, the ratchet tensioner ensures stable installation of the fixture and the product, as well as consistency in the pulling force after installation by different workers, improving the stability of subsequent tests and experiments and increasing the first-time accuracy of the tests.

[0013] To better understand the specific installation process of this achievement, the following explanation is provided in conjunction with the tooling structure diagrams 1 and 2 and the installation method diagram 3.

[0014] (1) First, connect the signal line of the signal simulator through the signal line interface of the tooling, then connect the elastic strap 4 with its buckle 10 to ensure that there is sufficient tension after the tooling is put on. Then connect the two non-elastic straps 3 and 5, and the ratchet tensioners 9 and 11, and leave enough space. (2) Put the tooling on the surface of the conical product and fix the tooling in place by the tension of the elastic strap. Then adjust the length of the non-elastic strap, but keep it loose. (3) Connect the tooling to the product surface according to the positioning pins 2 and 8. Then press the tooling with one hand until the wave-absorbing surface 7 can no longer be compressed. (4) Keep the tooling pressed with one hand and tighten the ratchet tensioners 11 and 2 with the other hand until the tooling is stably fixed on the product surface.

[0015] The tooling of this invention is fixed at both ends with non-elastic straps and ratchet tensioners, which improves the consistency of tooling installation in each test, improves the stability of installation, reduces human interference, reduces the possibility of electromagnetic leakage, and improves the accuracy of radio altimeter testing.
