A sealing detection system for an intercooler intake pipe and its application method

Abstract

The invention discloses a sealing detection system of an intercooling front intake pipe, and a use method thereof. The sealing detection system comprises a water tank, a control cabinet arranged on one side of the water tank, a detection device arranged on an upper edge of the water tank, and a lifting device located in the water tank. Compared with the prior art, the sealing detection system disclosed by the invention has the advantages that the intercooling front intake pipe is pre-fixed by a convex block and the intercooling front intake pipe is fixed by the cooperation of a ''U''-shaped ring and a nut, so that the intercooling front intake pipe is fixed firmly, and the device is not loose; a pipe head is sealed by a sealing device, and the movement of the sealing device is limited by afastening device, thereby ensuring the strict sealing of the pipe head, and accordingly, the sealing effect is good; and a clamping portion is arranged on a vertical limiting rod of the sealing device, the clamping portion is close fit with a clearance to prevent the occurrence of a gap between a gland and the pipe head when the fastening device is screwed, thereby avoiding the influence of the poor sealing effect of the pipe head on the detection result and playing a secondary limiting role, and furthermore, the system is simple in overall structure, convenient to use, good in sealing and detection effects and suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of automobile engines, in particular to a sealing detection system for an intercooler front intake pipe and a method for using the same. Background technique [0002] The intercooler intake pipe is a pipe part used for engine air intake. The existing intercooler intake pipe is made of aluminum alloy material to reduce the weight of the engine. It is a high-strength and lightweight product. [0003] However, the intercooler intake pipe, as an intake pipe fitting, requires no air leakage during use, and the sealing of the parts needs to be tested; since the intercooler intake pipe is a long pipe with 5 bends in shape, two pipes There are also angles of 3° and 10° between the head and the horizontal direction; it makes it difficult to make sealing tooling and parts clamping; [0004] In the usual sealing test, it is necessary to fix the parts. Due to the irregular shape of the pipe fittings, it is necessary to...

Problems solved by technology

[0003] However, the intercooler intake pipe, as an intake pipe fitting, requires no air leakage during use, and the sealing of the parts needs to be tested; since the intercooler intake pipe is a long pipe with 5 bends in shape, two pipes There are also angles of 3° and 10° between the head and the horizontal direction; it makes it difficult to make sealing tooling and parts clamping;

[0004] In the usual sealing test, it is necessary to fix the parts. Due to the irregular shape of the pipe fittings, it is necessary to compare the shape of the blank with the block. For the existing method, the production of tooling is labor-intensive, and the fixation can only be fixed with ordinary pressure plates. method, the operation is cumbersome, and the efficiency is relatively low, so it needs to be improved

[0005] In the existing patent application, there is no systematic seal detection technology for the intercooler intake pipe. The technology in this field is relatively blank in China. Therefore, designing a reasonable seal detection technology for the intercooler intake pipe is currently in the airtightness test. urgently needed
