Abstract

The invention discloses a caliper disc brake vacuum leakproofness test device comprising a sealed body. A sealed cavity for accommodating a caliper disc brake is arranged in the sealed body. A fixation device for arranging the caliper disc brake is arranged in the sealed cavity. An air compressor is further comprised. The air compressor is connected with a pipeline on / off device. The pipeline on / off device is connected with a ventilation pipeline. The ventilation pipeline is connected to the sealed cavity. An air pressure gauge for testing the pressure in the caliper disc brake is further arranged outside the sealed body. The test end of the air pressure gauge is extended into the sealed body. The caliper disc brake vacuum leakproofness test device of the invention has the following advantages the device has advantages of simple manufacture, convenient operation and reliable test result can be realized, and can be used to realize caliper disc brake process 100% vacuum leakproofness tests.

Description

technical field [0001] The invention relates to a test and detection device, in particular to a vacuum tightness test device for a caliper disc brake. Background technique [0002] According to "The People's Republic of China Machinery Industry Standard JB / T10917-2008 Caliper Disc Brake" 5.1.3 Vacuum sealing performance test, such as figure 2 As shown, in the traditional automobile caliper disc brake vacuum tightness test device, it is necessary to evacuate the brake line of the caliper disc brake 2 through the vacuum pump 8, the pipeline breaker 5 and the ventilation line 6 to After the absolute pressure is 250±50Pa, then the vacuum tightness test is carried out by measuring with the air pressure gauge 7. This test has very high requirements on the vacuum pump used. Ordinary vacuum pumps cannot meet the vacuum degree required by the test, so expensive professional vacuum pumps can only be used. It is difficult for ordinary manufacturers to conduct 100% vacuum tightness te...
