The invention discloses an automobile air conditioner pipeline double-sealing structure and a machining method thereof. The double-sealing structure of the automobile air conditioner pipeline comprises a core pipe, a first sealing ring, a second sealing ring, a nut and a stud, the first sealing ring and the second sealing ring are arranged on the core pipe in a sleeved mode and distributed in a spaced mode, the core pipe is sleeved with the nut, the stud is used for being connected with the nut, a gap is formed between the core pipe and the nut, and the stud can stretch into the gap and is connected with the nut in a matched mode. An annular boss is arranged in the stud, the core tube is in interference fit with the annular boss, and a blocking table is further arranged on the core tube. The first sealing ring is clamped by radial pressure generated by interference fit between the inner surface of the stud and the core tube to form radial sealing; when the stud is connected with the nut in a matched mode, the blocking table on the core pipe is matched with the annular boss to clamp the second sealing ring to form axial sealing, and the sealing structure combining the axial sealing and the radial sealing is adopted, so that the problem of leakage of an air conditioner caused by eccentric structure of the radial sealing is effectively solved.

    本发明公开了一种汽车空调管路双密封结构及其加工方法。其中该汽车空调管路双密封结构包括芯管、套设于芯管并呈间隔分布的第一密封圈和第二密封圈、套设于芯管上的螺母、以及用于与该螺母连接的螺柱,该芯管与螺母之间具有间隙,该螺柱可伸入该间隙中并与螺母配合连接,该螺柱内设有环形凸台,该芯管与环形凸台过盈配合,该芯管上还设有挡台。通过螺柱内表面与芯管过盈配合产生的径向压力夹持第一密封圈形成径向密封;通过螺柱与螺母配合连接时,并通过芯管上的挡台与环形凸台配合夹持第二密封圈形成轴向密封,通过采用轴向密封和径向密封相结合的密封结构,有效解决径向密封因结构偏心而导致空调出现泄漏的问题。
