Abstract
Description
Technical Field
[0001] This utility model relates to the field of irregular tubular antenna detection, and more specifically to a tooling for detecting the spatial shape and dimensions of irregular tubular antennas. Background Technology
[0002] Due to the unique and complex structure of irregularly shaped tubular antennas, their shape differs from traditional straight-rod tubular antennas. Depending on the actual installation location, the product shape may have certain angles of bending or tilting. Traditional dimensional measurement methods can only roughly assess its length, width, and height. Existing equipment cannot guarantee efficient and accurate detection of the dimensional and positional dimensions of critical installation locations. If defects such as excessive bending or insufficient tilting angle are found, installation may be impossible or result in excessive overall stress after installation. Currently, there is a lack of rapid dimensional and positional inspection methods and equipment for irregularly shaped tubular antennas. Employees rely solely on comparison with standard samples during inspection, which significantly increases labor costs and results in low efficiency, low accuracy, and a frequent risk of misjudgment. The inventors, referencing a digital model of an actual installation of the irregularly shaped tubular antenna, set positioning posts at key assembly locations and designed this dimensional and positional inspection fixture for irregularly shaped tubular antennas by simulating the actual assembly process. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of existing traditional size detection methods and equipment, and to provide a method and tooling that can quickly detect the shape and size of irregular tubular antennas, so as to detect abnormalities in time, make timely improvements, ensure the stable installation of antenna products, and reduce customer complaints.
[0004] To achieve the above objectives, this utility model employs the following design scheme:
[0005] A fixture for detecting the shape and position dimensions of an irregular tubular antenna includes: a fixture fixing base plate and at least one positioning block for fixing a support frame of the irregular tubular antenna to be tested. The positioning block is installed on the fixture fixing base plate and matches the installation angle of the support frame.
[0006] Multiple positioning posts, determined according to the digital model diagram, are used to detect the key shape and size dimensions of the irregularly shaped antenna. Each positioning post is installed in a corresponding positioning groove on the fixture's fixed base plate. The fixture determines whether the shape and size dimensions of the irregularly shaped tubular antenna are abnormal by judging the position or stress condition of the antenna relative to the positioning post.
[0007] Traditional antenna assembly dimension inspection is often limited to measuring data such as length, height, and width. However, this traditional measurement method is only effective for regularly shaped tubular antennas. For irregularly shaped tubular antennas with certain bends and angles, using traditional dimensional measurement methods is not only time-consuming but also cannot guarantee the accuracy of spatial dimensional measurement. The proposed fixture for inspecting the dimensional dimensions of irregularly shaped tubular antennas abandons the time-consuming and labor-intensive inspection methods using traditional measuring tools, ensuring both high inspection efficiency and antenna inspection accuracy.
[0008] A further technical solution of this utility model is as follows:
[0009] Furthermore, the positions and angles of the positioning blocks and positioning posts are replicated one-to-one onto the testing fixture based on the actual installation digital model of the irregular tubular antenna. According to the installation digital model of the irregular tubular antenna, the installation positions, heights, and angles of the front and rear support frames of the antenna under test are determined. Support frame positioning blocks matching the installation angles of the support frames are fabricated and fixed to the fixture's base. Simultaneously, referring to the digital model of the antenna's key installation positions, the positions of the positioning posts used for dimensional and positional inspection are confirmed, and positioning slots are cut squarely at the corresponding positioning post positions for post fixation. During actual testing, the irregular tubular antenna under test, assembled with the support frame according to standard assembly requirements, is installed onto this testing fixture. After seamlessly fitting the support frame and the support frame positioning blocks, it is observed whether the tubular antenna can be inserted into the positioning post or whether there is tight contact and stress between the tubular antenna and the positioning post to determine whether the dimensional and positional dimensions of the irregular tubular antenna are qualified.
[0010] Furthermore, the height and angle of the positioning block or the position of the positioning post can be adjusted according to the different shapes and detection positions of the antenna under test, which is suitable for the detection of irregular tubular antennas with special shapes and dimensions.
[0011] Furthermore, the tooling is made of steel, ensuring stable tooling quality, high testing accuracy, easy operation, and long service life.
[0012] The beneficial effects of this invention are: it can effectively detect abnormalities in the shape and size of irregular tubular antennas, improving the problem of false detection. The entire detection process is both efficient and accurate. By utilizing the principle of simulating actual assembly, product abnormalities can be clearly identified at a glance, eliminating complaints and rework costs caused by product misjudgment. It also reduces the workload of inspection personnel and lowers labor costs. Attached Figure Description

[0014] Figure 2This is a front view of the fixture for detecting the shape and position dimensions of the irregular tubular antenna described in this utility model;
[0015] Figure 3 This is a schematic diagram of the actual product testing of the irregular tubular antenna shape and position dimension testing fixture described in this utility model; Detailed Implementation
[0016] This embodiment relates to a fixture for detecting the shape and size of an irregularly shaped tubular antenna, such as... Figure 1 , 2 As shown in Figure 3, the fixture mainly includes a base plate 1, two positioning blocks 2 and 3 for mounting the front and rear support frames of the antenna under test, and four positioning posts 4 for detecting the shape and dimensions of the irregular tubular antenna. The positions and angles of the positioning blocks of the front and rear support frames, as well as the positioning grooves of the positioning posts, are replicated one-to-one onto this testing fixture according to the actual installation digital model of the irregular tubular antenna. By installing the antenna under test onto the testing fixture and judging the position or stress of the antenna relative to the testing positioning posts, it is determined whether the shape and dimensions of the irregular tubular antenna are abnormal.
[0017] The specific usage steps are as follows:
[0018] Step 1: Confirmation of Testing Fixture and Preparation of Antenna to be Tested: Confirm the testing fixture before testing to ensure that the support frame positioning block 2 and positioning block 3 are properly installed with the fixture fixing base 1, the nuts are tightened without abnormalities, there are no foreign objects in the assembly position of the support frame, and the testing positioning post 4 is fully engaged in the positioning groove on the fixture fixing base 1. Assemble the irregular tubular antenna to be tested and its corresponding support frame according to the standard installation requirements to form the antenna mast assembly.
[0019] Step 2, Product Inspection: Install the front and rear support frames of the antenna mast assembly into the corresponding support frame positioning blocks 2 and 3, ensuring installation according to the directional arrows on the inspection fixture. After tightening the nuts at the mounting holes, ensure seamless assembly between the bottom surface of the support frame and the mounting surfaces of support frame positioning blocks 2 and 3. Observe whether the irregular tubular antenna under test can be completely inserted into the inspection positioning post without tight contact or stress. If the antenna cannot be inserted into the positioning slot, or if the antenna mast can be inserted but there is tight contact and significant stress between the mast and the positioning post, it indicates that the shape and dimensions of the irregular tubular antenna at that inspection location are abnormal. This product is defective and requires improvement of the production process or technology. Immediate detection and feedback of any abnormalities are crucial for timely loss prevention and improvement, preventing defective products from reaching customers and causing installation problems and customer complaints.
[0020] By flexibly adjusting the height, angle, or position of the positioning block of the tooling according to the different shapes and detection positions of the antenna under test, it can be adapted to the detection of the shape and size of various irregular tubular antennas with different shapes and multiple detection positions. This has great significance for horizontal expansion and promotion.
[0021] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
