Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The utility model discloses an engine oil heat exchanger core pressing tool which consists of a shell, an O-shaped ring, a compression ring 2 and a fastener, as shown in figure 1. The shell 1 is formed by welding a seamless steel pipe 13, two flanges 14, a hanging seat 12 and an air inlet seat 11 with a quick connector, wherein O-shaped ring grooves are formed in the end faces of the two flanges; the dimensions of the housing 1 are adapted to the core 5 to be tested, and the core 5 can be fitted therein exactly as shown in fig. 1. The structure of the pressing ring 2 is shown in fig. 3, a hole slightly larger than the core body 5 is processed in the middle of the pressing ring 2, and the pressing ring can be sleeved at the end part of the core body 5; flange holes are formed around the compression ring 2 and are used for being connected and fastened with the shell 1.
When the pressing tool is used, the installation mode is shown in fig. 3, the shell 1 is sleeved on the engine oil heat exchanger core 5, the O-shaped rings 4 are arranged at the two ends of the shell, the pressing ring 2 is arranged, the fastening piece is fastened, the fastening piece is a bolt, the two sides of the tool and the core 5 form a seal, at the moment, a space between the outside of the core 5 to be detected and the inside of the tool shell 1 is a closed cavity, the air inlet seat in the middle of the shell 1 is filled with air with certain pressure, and the air inlet seat is integrally hung into water, so that the air inlet seat can be observed from the tube plates 51 at the two sides of the core 5, as shown in fig. 4. If there is leakage, the leakage part can emit bubbles, and the position of the bubbles attached to the core tube plate can be clearly confirmed in water, so that the specific position of the leakage can be easily observed and locked, and quick disposal can be performed.
In order to maintain the tightness of the cavity between the housing and the core, the sealing of both ends of the core and the tooling is critical, so that a suitable sealing means can be used according to circumstances, for example, a sealing ring is directly added to the core and the tooling housing 1. The best mode is that the compression ring 2 and the core body, the compression ring 2 and the tool shell 1 are kept well sealed.
The shell 1 is also welded with at least two hanging seats, so that the hanging stability can be ensured, more hanging seats can be additionally arranged if the product is required to be detected, and different postures can be realized, so that the observation is convenient.
The air inlet seat is provided with a quick connector for quick air charging and discharging, so that the efficiency is improved.
The tool has the advantages that the structure is simple, the core body and the tube plate are exposed, the core body is pressed inwards by gas, the pressing mode and the observing mode are reverse to the conventional thought, the efficiency is high, the leakage point finding is very accurate, the use is very convenient, and the time and the labor are saved. The core pressing and quick leakage point searching requirements of the engine oil heat exchanger can be met, the production efficiency is greatly improved, the labor intensity of operators is reduced, and the production cost is saved.
