Problems solved by technology

The entire testing process is manual, and the sealing performance of each mounting hole needs to be tested one by one, and the testing efficiency is extremely low
Especially when the airtightness of the duplexer shell is poor and needs to be repaired, it is necessary to repeatedly use the screw holes of the joint flange to be fixed with screws before testing. In this way, it is easy to cause wear to the screw holes of the joint flange and cause the entire Parts are scrapped, which increases production costs

Embodiment Construction

[0019] Such as figure 1 , figure 2 , image 3 with Figure 5 As shown, the fixture for automatic testing of the performance of the die-casting duplexer of the present invention includes a bottom plate 17 and a top plate 4. Two uprights 3 are provided between the left and right opposite sides of the bottom plate 17 and the top plate 4, and the upper and lower ends of the uprights 3 are connected to the top plate respectively. 17 is connected to the bottom plate 4 to form a quadrilateral frame. A positioning plate 14 for fixing the device under test 13 is fixed on the bottom plate 17. The positioning plate is rectangular. The four corners of the positioning plate 14 are fixed with upwardly protruding right-angle ribs 18, the right-angle ribs 18 The inner side of the device is adapted to the corresponding corner of the device under test 13. A first simulated sealing mechanism is provided on the bottom plate 17 on the left side of the positioning plate 14. The first simulated se...

Abstract

The invention relates to a jig for automatic performance testing of a die-casting duplexer. Generally speaking, it is a fixture used to automatically test the sealing performance of the duplexer shell. Its characteristics include a bottom plate and a top plate. There are columns connected between a pair of opposite sides of the bottom plate and the top plate. There is a positioning plate for fixing the device under test on the bottom plate. There is a first simulated sealing mechanism on the bottom plate on at least one side of the positioning plate. The first simulated sealing mechanism is composed of a first cylinder, a bearing block, a flange block, a first sliding column between the flange block and the bearing block, a first spring, and a sealing ring outside the flange block. Using the jig to test the performance of the die-casting duplexer has high test efficiency and low production cost.

Description

Technical field [0001] The invention relates to a clamp. Specifically, it is a fixture used to automatically test the sealing performance of the duplexer housing. Background technique [0002] In the communication equipment manufacturing industry, it is known that the housing of the communication equipment duplexer is a rectangular parallelepiped. The housing is an aluminum die-casting part. There are many waterproof connectors on the side walls of the housing, some of which are installed by the customer. The entire product needs to be used externally. If the airtightness of the housing is not good, it will affect the performance of the entire device and cause the entire communication equipment to paralyze. In order to avoid the above problems, it is necessary to test the airtight performance of the housing of the duplexer of the communication equipment. [0003] At present, the method used to test the airtight performance of the housing of the communication equipment duplexer is...
