Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile air conditioner accessory production, more particularly to a pipe plugging device for air conditioner pipe end. BACKGROUND

[0002] The pipe used in the automobile air conditioner is mostly a special-shaped pipe, which can be adjusted in shape according to the size of the installation space and the arrangement of the surrounding pipes. The heat pump air conditioner pipe has a special structure, with a metal special-shaped pipe at both ends and a hose in the middle section. Therefore, the heat pump air conditioner pipe cannot be cast in one piece and needs to be assembled with the metal pipe and the hose.

[0003] Most of the pipe plugging machines on the market are only compatible with regular-shaped pipes. For special-shaped pipes, there is no matching tooling fixture. Therefore, the pipe plugging work of the heat pump air conditioner pipe is mostly completed by manual labor. The problem with manual labor is that the precision is not enough and the pipe plugging depth is not enough.

[0004] Patent No. 202222029377.2 discloses a multi-position pipe plugging device for a heat pump air conditioner pipe. However, the hose of the above-mentioned device is a straight pipe type, and the fixture tooling also adopts a straight pipe fixing method. This pipe plugging device is not suitable for cases where the hose is curved.
