Problems solved by technology
When a waveguide coupler is tested, it is necessary to loosen the bolts, remove the flange, and then fix the flange to the next waveguide coupler, which makes the detection efficiency extremely low, and it is difficult to adapt to the detection of a large number of waveguide couplers.
Especially when the airtight performance of the waveguide coupler is poor and requires maintenance, repeated disassembly and installation of the flange will easily cause wear to the screw holes around the waveguide port, and in severe cases, the entire waveguide coupler will be damaged

Embodiment Construction
[0018] Such as figure 1 , figure 2 with image 3 As shown, the jig for testing the airtightness of the waveguide coupler of the present invention includes a bottom plate 30, which is rectangular, and a support block 18 for supporting the waveguide coupler under test is provided in the middle of its upper surface. A base 29 is installed on the upper surface of one end of the bottom plate 30 , and upper bumps 27 for clamping the waveguide coupler under test are processed around the base 29 . A circular pit 31 is processed on the upper surface of the base 29 , and a test disk 16 is arranged in the circular pit 31 . The diameter of the test disc 16 is adapted to the diameter of the round hole 31 and the two are fitted in a vertical sliding manner. Four first springs 32 are arranged between the test disc 16 and the bottom of the round pit 31 . Pipe holes are processed on the pit wall of the circular pit 31, and a trachea 28 is pierced in the pipe holes, and the inner end of th...

The invention relates to a fixture used for testing air tightness of a waveguide coupler. The fixture comprises a bottom plate, a support block is arranged in the middle of an upper surface of the bottom plate, a base is arranged on an upper surface of one end of the bottom plate, and upper projections are arranged on the periphery of the base. A round pit is arranged on the upper surface of the base, and a test disk is arranged in the round pit. First springs are arranged between the periphery of the bottom of the round pit and that of the test disk. An air pipe is arranged outside the base, and one end of the air pipe penetrates through the base and is connected on an inner surface of the test disk. One end of the bottom plate adjacent to the base is provided with a vertical arm, and a cantilever is connected with an upper end of the vertical arm. A first pin seat is arranged on the cantilever. A first drawing mechanism and a first compression mechanism are sequentially connected below the first pin seat. The other end of the bottom plate is provided with a second pin seat, a second drawing mechanism and a second compression mechanism are sequentially connected between the second pin seat and the support block. By the aid of the fixture, detection efficiency can be improved and damage of the waveguide coupler is avoided.
Description
technical field [0001] The invention relates to a clamp. Specifically, it is a jig used to fix the waveguide coupler when testing the airtightness of the waveguide coupler. Background technique [0002] It is well known in the wireless communication equipment manufacturing industry that waveguide couplers are indispensable products for wireless communication equipment. Its airtight performance is directly related to the operation status of the whole set of communication equipment. Therefore, the airtight performance of the waveguide coupler must be tested before leaving the factory. [0003] At present, when testing the airtight performance of the waveguide coupler, it is mostly used to install flanges on the three waveguide ports of the waveguide coupler, and to process a through hole for ventilating into the waveguide coupler on one flange. One waveguide port, the method of ventilating into another waveguide port, and then use the airtight tester to test the airtight pe...
