Description

Technical Field

[0002] The air conditioning pipe is a dedicated connecting pipe between the outdoor unit and the indoor unit. The connecting pipe is filled with refrigerant.

[0003] In cooling mode, the indoor unit absorbs heat from the vehicle, turning the refrigerant into a low-pressure solid and then discharging it through a larger air conditioning pipe to the outdoor unit. The refrigerant is then compressed by the compressor, reaching a high temperature and high pressure before entering the outdoor unit's heat exchanger, where the fan rotates, releasing the heat. The refrigerant then returns to a moderate temperature and pressure before entering the vehicle through another air conditioning pipe.

[0004] After processing and forming, the air-conditioning pipe needs to be placed in a predetermined workstation for cutting. After cutting, other connectors need to be inserted into the end of the air-conditioning pipe. In order to ensure the airtightness of the connection between the air-conditioning pipe and other connectors, the end of the air-conditioning pipe is generally sleeved on the port of the other connector in an interference fit manner. However, in the process of connecting other connectors to the end of the air-conditioning pipe, the air-conditioning pipe is prone to collapse due to the insertion of the connector, and the air-conditioning pipe needs to be replaced or re-cut, which has an adverse effect on the assembly efficiency of the air-conditioning pipe and urgently needs improvement.

[0034] Please also refer to Figure 1 and Figure 2 The air conditioning pipe reaming device provided by the present invention will now be described. The air conditioning pipe reaming device includes a positioning mechanism 1 and a reaming mechanism 2. The positioning mechanism 1 includes a positioning plate 11 and a positioning head 12. The positioning plate 11 has a positioning slot 110 at its bottom. The length of the positioning plate 11 is parallel to a first horizontal direction a, and the depth of the positioning slot 110 is parallel to the vertical direction. The positioning head 12 can abut the bottom of the positioning slot 110 in the vertical direction. The reaming mechanism 2 includes a reaming shaft 21 that can rotate around itself.

[0036] In the above embodiment, preferably, the bottom of the positioning groove 110 and the positioning head 12 can form a cylindrical clamping space, so that the positioning groove 110 and the positioning head 12 can fix the air conditioning pipe more securely.

[0037] Based on the above embodiments, further, in order to drive the reaming shaft 21 to move, a feasible implementation method is proposed.
