The invention provides an automobile air conditioner refrigerating system pipeline double-sealing mechanism and a machining method, and belongs to the technical field of automobile air conditioner refrigerating system pipeline sealing structures. According to the double-sealing mechanism, due to the design that the two sealing grooves are formed in the peripheral face of the core pipe, the sealing rings are arranged in the two sealing grooves in a sleeved mode respectively, and the hose buckled and pressed between the core pipe and the sleeve is buckled and pressed on the sealing rings at the same time, the problem that in the prior art, the number of machining procedures of a sealing mechanism is large, time is long, and consequently the production cost is not easy to control is solved. The pipeline double-sealing mechanism of the automobile air conditioner refrigerating system is installed at the pipeline connecting position among a compressor, a condenser, an expansion valve and an evaporator and comprises a core pipe, a sleeve arranged on the core pipe in a sleeving mode and a hose buckled and pressed between the core pipe and the sleeve, and two sealing grooves are formed in the peripheral face of the core pipe. Sealing rings are sleeved with the two sealing grooves respectively, and the hose buckled and pressed between the core pipe and the sleeve is buckled and pressed on the sealing rings at the same time.
