egr cooler core assembly machine

Abstract

The invention relates to an exhaust gas recirculation (EGR) cooler core body assembly machine and belongs to the technical field of machinery. The EGR cooler core body assembly machine comprises a machine frame. A work table is arranged on the machine frame, an oil cylinder seat is arranged on the work table, and a core body clamp is arranged on a linear guide rail of the work table and comprises a sliding block matched with the linear guide rail. The sliding block is fixed at the lower end of a base plate, a side plate is fixedly arranged on the upper end face of the base plate, the upper end of the side plate is provided with an upper template, and a cylinder is arranged on the lateral side of the upper template. The hydraulic cylinder on the EGR cooler core body assembly machine can provide enough pressure drop, and a heat dissipation threaded tube with a flaring structure is pressed into a fixing plate. A guiding shaft arranged at the lower end of the machine frame can guide installation of the heat dissipation threaded tube and is high in assembly efficiency. The EGR cooler core body assembly machine is simple, reliable, convenient to use, low in manufacture cost and easy to maintain.

Description

technical field [0001] The invention relates to an EGR cooler core assembly machine, which belongs to the technical field of machinery. Background technique [0002] At present, EGR refers to the exhaust gas recirculation system. The structure of the EGR cooler is mainly a shell-and-tube type, in which threaded pipes are used for heat exchange, that is, grooves and raised thread grooves are made on the surface of the tube embryo. The structure greatly increases the heat exchange area, thereby greatly improving the heat exchange efficiency of the EGR cooler. [0003] At present, the installation of heat dissipation threaded pipes is usually done manually in China. There are usually more than one hundred heat-dissipating threaded pipes in the core of a heavy-duty vehicle cooler. Manual installation of so many pipes is time-consuming and labor-intensive, and the assembly quality cannot be guaranteed. At the same time, for some core structures with special requirements, the end...

Problems solved by technology

There are usually more than one hundred heat-dissipating threaded pipes in the core of a heavy-duty vehicle cooler. Manual installation of so many pipes is time-consuming and labor-intensive, and the assembly quality cannot be guaranteed. At the same time, for some core structures with special requirements, the ends of the heat-dissipating threaded pipes It usually has a flared structure, and the heat-dissipating threaded pipe needs a lot of pressure to be pressed into the fixed plate. It is difficult to provide enough pressure for manual installation. Therefore, it is urgent to develop an assembly machine to replace manual installation.
