A filter assembly air tightness automatic detecting device

Abstract

The invention brings forward a filter assembly airtight automatic detecting device comprising a frame and a filter assembly, wherein one end of the frame is fixed with a bottom plate through bolts, and one side of the bottom plate is welded and fixed with a plurality of supporting blocks. A large water tank is placed on the corresponding ends of the supporting blocks. One side of the bottom plateis welded and fixed with a first bracket, and one side of the first bracket is fixed with a fixing plate through bolts. One side of the fixing plate is fixed with a reinforcing plate through bolts. One end of the reinforcing plate is fixed with a first air cylinder fixing plate, and the other end of the reinforcing plate is fixed with a supporting plate. One side of the supporting plate is fixed with a plurality of mounting jigs and a plurality of pressing members through bolts. Air tightness testing of four filters can be completed in a batch in twenty-five seconds, which greatly reduces theworkload and labor intensity of the employees. Furthermore, the use of automatic equipment for inspection can also avoid missed detection. The assembly qualification rate of products is further improved.

Description

technical field [0001] The invention relates to the technical field of filter assembly airtight detection, in particular to an automatic airtight detection device for a filter assembly. Background technique [0002] During the working process of the engine, metal wear debris, dust, carbon deposits oxidized at high temperature, colloidal sediment, water, etc. are continuously mixed into the lubricating oil. The function of the filter is to filter out these mechanical impurities and colloids and keep the lubricating oil If the filter is not well sealed, it will cause oil leakage and affect the life of the engine. At present, the air tightness test of the gasoline and oil filter assembly is manually inflated and pressurized. Put it into the water to test the air tightness. After the test, the air pressure is manually released, which is inefficient. It takes two minutes to test a single filter, and the manual operation is cumbersome, and it is easy to miss the test.
