Description

Technical Field

[0002] After the oxygen sensor is produced, a series of tests are required to ensure that the oxygen sensor can be used normally. A combustion test is required when testing the oxygen sensor. The combustion test is to place the oxygen sensor after production on the assembly rack, put the sensing end of the oxygen sensor into the detection furnace through the assembly rack, and perform a high-temperature combustion test. Then, through the matching wiring harness on the combustion detection equipment, the comprehensive combustion test performance of the oxygen sensor to be tested under different temperature conditions is sensed. At present, the ordinary assembly rack has the following problems in actual use: 1. The bottom frame in the ordinary assembly rack is not non-slip. The assembly rack is usually placed on a smooth work surface or stacked on each other. The non-slip bottom frame is easy to shift on a smooth work surface or when it is stacked on each other, causing the assembly rack to fall and the oxygen sensor to fall, and the oxygen sensor cannot be safely placed; 2. The ordinary assembly rack has no adjustable placement components, and can only place oxygen sensors of the same model and size. When testing oxygen sensors of different models and sizes, multiple assembly racks with different placement holders are required, which has high production costs and occupies work space. To this end, we have developed an easily adjustable non-slip oxygen sensor combustion test assembly rack. Summary of the invention

The adjustment placement component 4 can adjust the position according to different oxygen sensor models without interfering with each other. It is suitable for popularization when performing combustion tests on oxygen sensors.
