Abstract

The invention discloses an exhaust flange assembly. The assembly comprises a flange base, a flange boss and a supporting frame, the flange boss is fixedly connected to the upper surface of the flangebase, the end, far away from the flange base, of the flange boss is fixedly connected with the supporting frame, the side surface of the supporting frame is fixedly connected with a first flange connecting block, the side, close to the first flange connecting block, of the top end of the supporting frame is fixedly connected with a second flange connecting block, a first hole is formed in the side, close to the flange boss, of the first flange connecting block, and a second hole is formed in the middle of the surface of the second flange connecting block. According to the exhaust flange assembly, the sealing performance test and the water pressure test are carried out, the test pressure is 100 KPA, non-leakage of 5 seconds is performed, the tested exhaust flange assembly is manufactured through machining, the manufactured exhaust flange assembly has good sealing performance and water pressure resistance, the total weight is 1.459 kg, the weight of the flange is controlled on the premise that the quality is not reduced, and the weight range of the flange installation is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an exhaust flange assembly. Background technique [0002] Auto parts (autoparts) are the various units that make up the whole car and a product that serves the car.
