Abstract
Description
Technical Field
[0001] This utility model relates to a high-precision positioning device for the ridge of a four-ridged horn antenna, belonging to the field of radar electronic engineering technology. Background Technology
[0002] Quad-ridged horn antennas are commonly used signal transmitting devices and have wide applications in radar electronics. Their working principle involves adding ridges to the waveguide and horn opening of the horn antenna to broaden the operating frequency band. Therefore, these horn antennas offer advantages such as high gain, low impedance, small size, and ease of connection to transmission lines. Quad-ridged horn antennas above 18GHz have relatively small ridges and confined space within the horn housing. Currently, installation of quad-ridged horn antennas is generally done manually, specifically by using tweezers to hold the ridges. This often leads to the following problems: 1. Low installation efficiency; 2. Low positioning accuracy, as high-frequency horn antennas require high positioning accuracy for the ridges, and installation deviations are often unacceptable; 3. Significant internal wear, as the sharp edges of the ridges inevitably scratch the internal cavity during manual installation, resulting in poor final antenna performance. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a high-precision positioning device for the ridge of a four-ridged horn antenna, which can improve the installation accuracy and efficiency of the ridge of the four-ridged horn antenna, and at the same time reduce the wear of the inner cavity of the ridge of the four-ridged horn antenna.

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the protection scope of the present invention.
[0020] Example 1
[0021] like Figures 1 to 4 As shown, this utility model discloses a high-precision positioning device for the ridge pieces of a four-ridged horn antenna, including a base plate 1 with a column 6 underneath for supporting the base plate 1. A positioning ring 13 is provided on the base plate 1, which is used to place the horn housing 10 and position it. Positioning scale lines 9 are provided on the base plate 1 and the positioning ring 13. Before inserting the horn housing 10 into the corresponding ridge piece, the scale on the horn housing 10 needs to be aligned with the positioning scale lines 9. A support column 14 is provided on the base plate 1, located at the center of the positioning ring 13, for inserting the horn housing 10. A ridge piece support core 12 is provided at the upper end of the support column 14, serving as a guide for ridge piece insertion. A guide column 7 is provided directly below the support column 14 on the base plate 1, and a handle 5 is provided below the base plate 1. The handle 5 is slidably fitted onto the guide column 7, allowing it to move up and down. Several clamping mechanisms arranged in a circle are provided between the base plate 1 and the handle 5. The clamping mechanism includes a clamping rod 3, the middle of which is rotatably connected to a support rod 2 mounted on the base plate 1. The outer end of the clamping rod 3 is rotatably connected to the outer end of an L-shaped drive rod 4, and the inner end of the L-shaped drive rod 4 is rotatably connected to a handle 5. When the operator moves the handle 5 upward, the moving handle 5 will drive the L-shaped drive rod 4 upward, which in turn will drive the inner end of the clamping rod 3 downward until it contacts the outside of the speaker housing 10.
[0022] The working process of this utility model is as follows: First, place the speaker housing 10 inside the positioning ring 13 on the base plate 1. Then, rotate the speaker housing 10 so that the scale line on the speaker housing 10 is aligned with the positioning scale line 9. Move the handle 5 upward, and drive the inner end of the clamping rod 3 downward through the L-shaped drive rod 4 to clamp and fix the speaker housing 10 externally. Finally, insert the corresponding ridge piece into the speaker housing 10. After the entire process is completed, move the handle 5 downward to release the speaker housing 10, insert the next speaker housing 10, and repeat the process.
[0023] This invention features a positioning ring on the base plate, with positioning scale lines on both the base plate and the positioning ring to position the ridges of the four-ridged horn antenna. Several clamping mechanisms arranged in a circle between the base plate and the handle are used to clamp the ridges of the four-ridged horn antenna, which can greatly improve the installation accuracy and efficiency of this type of antenna, eliminate a large number of human installation errors in mass production, ensure the consistency of subsequent horn debugging, and reduce the wear of the inner cavity of the ridges of the four-ridged horn antenna.
[0024] Example 2
[0025] like Figures 1 to 4 As shown, this utility model discloses a high-precision positioning device for the ridge pieces of a four-ridged horn antenna, including a base plate 1 with columns 6 underneath for supporting the base plate 1. The base plate 1 is rectangular in shape, and there are four columns 6 located at the four corners of the base plate 1. A positioning ring 13 is provided on the base plate 1, which is used to place the horn housing 10 and position it. Positioning scale lines 9 are provided on the base plate 1 and the positioning ring 13. Before the horn housing 10 is inserted into the corresponding ridge piece, the scale on the horn housing 10 needs to be aligned with the positioning scale lines 9. There are four positioning scale lines 9. A support column 14 is provided on the base plate 1 and at the center of the positioning ring 13, which is used to insert the horn housing 10. A ridge piece support core 12 is provided at the upper end of the support column 14, which is used for guiding the insertion of the ridge piece.
[0026] A guide post 7 is positioned directly below the support post 14 on the base plate 1. A handle 5 is located below the base plate 1, slidingly mounted on the guide post 7, allowing the handle 5 to move up and down. The handle 5 is approximately figure-eight shaped and is mounted on the upright post 6, which also guides the movement of the handle 5. Several clamping mechanisms are arranged in a circle between the base plate 1 and the handle 5. There are four clamping mechanisms, located on the four sides of the base plate 1. Each clamping mechanism includes a clamping rod 3, the middle of which is rotatably connected to the support post 2 mounted on the base plate 1. The outer end of the clamping rod 3 is rotatably connected to the outer end of an L-shaped drive rod 4, and the inner end of the L-shaped drive rod 4 is rotatably connected to the handle 5. Specifically, the clamping rod 3 is rotatably connected to the support post 2, the L-shaped drive rod 4, and the handle 5 via pins 11. When the operator moves the handle 5 upward, the moving handle 5 will drive the L-shaped drive rod 4 upward, which in turn will drive the inner end of the clamping rod 3 downward until it contacts the outside of the speaker housing 10.
[0027] In this invention, an upper magnetic ring 15 is sleeved on the guide post 7 below the base plate 1, and a lower magnetic ring 8 is sleeved on the guide post 7 above the handle 5. The upper magnetic ring 15 and the lower magnetic ring 8 are attracted to each other by opposite polarities. When the handle 5 moves upward until the upper magnetic ring 15 and the lower magnetic ring 8 are attracted together, the speaker housing 10 is fixed. The magnetic attraction mechanism provides convenience in operation.
[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
