Description

Technical Field

[0001] This utility model belongs to the field of wall thickness clamps, and in particular relates to a clamp for measuring the wall thickness of an antenna radome. Background Technology

[0002] Measuring the wall thickness of a radome is part of antenna performance testing. Typically, a specialized wall thickness fixture is used to support the radome, and then testing equipment measures the radome. Existing wall thickness measuring fixtures consist of a support column between two circular aluminum rings, with a nylon plate fixedly connected inside the aluminum rings. Holes are milled into the nylon plate according to the outer surface of the radome, and then the radome is embedded into the nylon plate.

[0003] Most of the wall thickness measurement tools currently used are developed for specific models of radomes. They require special fixtures to measure wall thickness, cannot adjust the size, have low applicability, and require temporary use of special fixtures during production conversion, resulting in high overall fixture costs due to the large number of spare fixtures.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] like Figures 1-7 As shown in the figure, this utility model embodiment provides an antenna radome wall thickness measuring fixture, including a support platform and a clamping base 200.

[0030] The support platform includes a circular chassis 110 and support rods 130 mounted on the chassis 110. In this embodiment, two sets of support rods 130 are used. In actual applications, the number of support rods 130 can be increased as needed. The different support rods 130 are all equidistant from the center point of the chassis 110.

[0031] The clamping seat 200 is disposed on the support rod 130. The clamping seat 200 includes a sliding clamp 210 and a sliding base 220. One end of the sliding base 220 is nested around the support rod 130 and slides along the support rod 130. The sliding clamp 210 slides on the sliding base 220. The sliding clamp 210 is provided with a sliding card seat 230 for limiting the position. The sliding clamp 210 abuts against the outer wall of the radome.

[0032] In this embodiment, the sliding direction of the sliding clamp 210 and the support rod 130 is perpendicular to the sliding direction of the sliding clamp 210 and the sliding base 220. The mutual sliding between the sliding clamp 210 and the support rod 130 can directly change the diameter of the clamping area to adapt to the testing and fixing needs of radomes of different diameters. The sliding of the sliding clamp 210 and the support rod 130 can be applied to the testing and fixing needs of radomes of different lengths. The multi-directional adjustment structure meets the fixing needs of radomes of different specifications, effectively improving the adaptability of the clamp and reducing the cost of using the clamp.

[0033] In a preferred embodiment of this invention, the sliding clamp 210 is provided with a front clamp 212 and a sliding cavity 211 for clamping. The support rod 130 passes through the sliding cavity 211 and penetrates the sliding clamp 210. The sliding clamp 210 is also provided with a guide groove 213. The sliding base 220 is provided with a guide rail 223, and the guide groove 213 slides on the guide rail 223. The sliding bracket 230 provides a limiting function for the sliding base 220. Specifically, the clamping effect generated by the bolted connection between the sliding bracket 230 and the sliding base 220 restricts the movement of the sliding clamp 210.

[0034] In this embodiment, the sliding bracket 230 is provided with a sliding groove 232, which engages with the side wall of the sliding cavity 211. The sliding base 220 is provided with a limiting screw hole 224, and the sliding bracket 230 is provided with a fixing screw hole 231 for assembling a limiting bolt. The limiting bolt for connecting the sliding bracket 230 and the sliding base 220 is assembled in the limiting screw hole 224 after passing through the sliding bracket 230, thus completing the fixed connection. The clamping force generated by the fastening effect increases the resistance of the sliding clamp 210 during the sliding process.

[0035] In this embodiment, the guide rail 223 is also provided with a scale for marking distances, which helps to calibrate the distance between the front clamp 212 and the center line of the chassis 110.

[0036] In a preferred embodiment of this invention, the sliding base 220 is provided with a clamping hole 221 and a bayonet 222. Both the clamping hole 221 and the bayonet 222 penetrate the sliding base 220. The clamping hole 221 is nested on the outside of the support rod 130. The clamping hole 221 and the bayonet 222 are connected and the bayonet 222 extends to the surface of the sliding base 220. When the bayonet 222 is provided with a locking bolt for fastening, the clamping hole 221 enhances the clamping force on the support rod 130.

[0037] In this embodiment, the side wall of the bayonet 222 is provided with a locking screw hole 225, and the locking bolt is arranged in the locking screw hole 225. The clamping hole 221 and the bayonet 222 are fixed in a way similar to the existing clamp connection method. The locking bolt at the bayonet 222 is mainly used to generate a locking force. The locking force reduces the size of the clamping hole 221 to enhance the clamping force on the support rod 130.

[0038] In a further preferred embodiment of this utility model, a buffer seat 120 is also provided on the chassis 110; the end of the radome is in contact with the buffer seat 120, and the height adjustment of the clamping seat 200 here is to allow radomes of different specifications to be supported by the buffer seat 120.

[0039] In this embodiment, the buffer seat 120 is made of nylon material. The buffer seat 120 is usually located at the center of the circular structure of the chassis 110, and a groove for supporting the antenna cover is provided at the center of the buffer seat 120.

[0040] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
