Description

Technical Field

[0001] The utility model relates to the technical field of satellite communication antennas, in particular to a satellite communication antenna testing tool. Background Art

[0002] Antennas are a crucial component of satellite communication systems, serving as the input and output channels for radio frequency signals from earth stations. The performance of the antenna system impacts the overall performance of the communication system. As specialized equipment, satellite communication antennas vary in form factor and interface. To meet the requirements of anechoic chamber electrical performance testing, specialized fixtures are designed. During testing, the fixtures are screwed into the mounting interface provided on the turntable to connect the turntable to the equipment.

[0003] The interface between the tooling and the turntable requires screw installation, which requires the cooperation of at least two operators. When the tooling and product are large in size and weight, assembly is relatively difficult, requiring three or more people to cooperate with each other for installation. To ensure the performance of the darkroom product installation turntable (lift), the operating space is limited. Operators are often unable to stand or crowded, which poses risks to operators. Or the position of the absorbing material needs to be temporarily adjusted to make room for the operation, and then reset after assembly is completed, which increases the preparation time before testing and reduces test efficiency. When assembling the tooling and turntable interface, accurate positioning is required for screw installation. The operator needs to manually align the position, and the screw holes often become misaligned or cannot be installed, requiring readjustment. This is inconvenient to operate, requires a certain amount of adjustment time, and has low assembly efficiency.

[0004] Usually, tooling assembly and cable interconnection before testing will take up a large part of the entire product testing time, resulting in low testing efficiency; when the number of products is large, repeated disassembly and assembly will cause testing, increasing the probability of errors. Utility Model Content

[0005] In view of the defects in the prior art, the utility model provides a satellite communication antenna test tool to solve the current problems of difficult installation of antennas and mounting turntables and low assembly efficiency.

[0006] The utility model provides a satellite communication antenna test tool, comprising:

[0007] Connecting plate;

[0008] A positioning pin is provided on the connecting plate;

[0009] A turntable mounting plate, wherein a mounting hole is formed on the turntable mounting plate corresponding to the positioning pin, and a mounting groove is formed on the outer side of the mounting hole;

[0010] A locking block is arranged in the mounting groove;

[0011] The chuck is matched with the turntable mounting plate, and a locking groove matched with the locking block is provided on the inner side of the chuck, and the inner wall of the locking groove includes an obliquely arranged guide section.

[0012] It can be seen from the above technical solution that the utility model provides a satellite communication antenna testing tool. When installing a satellite communication antenna, first align the positioning pin with the corresponding position of the turntable mounting plate, and then rotate the chuck to lock the tooling and the antenna, thereby achieving rapid locking of the antenna and the mounting turntable, simplifying the assembly process during satellite communication antenna testing.

[0013] Optionally, an elastic member is provided between the locking block and the locking groove. The elastic member allows the locking block to conform to the inner wall of the chuck. When the tooling switches between locked and released states, the antenna and turntable can be quickly locked by rotating the chuck in the released state, thereby improving test assembly efficiency.

[0014] Optionally, a roller is provided on the outer side of the locking block, and the roller slides along the inner wall of the locking groove.

[0015] Optionally, a cover plate is further provided on the locking block, the cover plate is bolted to the mounting groove, and the locking block is provided between the locking groove and the cover plate.

[0016] Optionally, the outer edge of the turntable mounting plate further includes a fixing groove, a spring pin disposed within the fixing groove, and a positioning groove disposed on the inner wall of the locking groove, wherein the spring pin and the positioning groove cooperate with each other. To prevent the fixture from loosening during product testing, the chuck is further rotated to engage the positioning groove and the spring pin, thereby achieving self-locking.

[0017] Optionally, a handle is provided on the outside of the chuck.

[0018] By adopting the above technical solution, this application has the following technical effects:

[0019] The satellite communication antenna test fixture provided by the utility model is used to realize the connection between the antenna and the darkroom turntable bracket. When installing the satellite communication antenna, the connection plate pre-assembled with the antenna is aligned with the corresponding position of the turntable mounting plate through the positioning pin, and then the chuck is rotated to lock the fixture and the antenna, thereby realizing the rapid locking of the antenna and the darkroom turntable bracket, thereby simplifying the assembly process during the satellite communication antenna test.

DETAILED DESCRIPTION

[0029] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0031] In this application, unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0032] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0034] See also Figure 1-2 The satellite communication antenna test fixture provided in this embodiment is connected to the installation turntable. When installing the satellite communication antenna, the connection plate 1 pre-assembled with the antenna is aligned with the corresponding position of the turntable mounting plate 3 through the positioning pin 2, and then the chuck 5 is rotated to lock the fixture and the antenna, thereby achieving rapid locking of the antenna 9 and the darkroom turntable bracket 10, simplifying the assembly process during satellite communication antenna testing.

[0035] It should be noted that the satellite communication antenna has a fixed mechanical interface, and a fixed column is adaptively provided on the connection plate for connecting to the mechanical interface of the satellite communication antenna.
