[0002] An air conditioner connecting pipe refers to a pipe in an air conditioner system through which a refrigerant flows to connect main refrigeration components such as heat exchangers, valves, and compressors. Usually, copper pipes are used. For systems with direct air supply and cold and hot water transportation.

[0003] During the production process of an air conditioner connecting pipe, in order to ensure the flatness of the pipe port and avoid the adverse effects of burrs at the pipe port on subsequent connections, the port needs to be ground. At this time, an end grinding device is required. To ensure that the center of the grinding plate is aligned with the center of the pipe to be ground when the grinding plate adapts to pipes of different sizes, some use a screw lifting method, which makes it inconvenient to rotate the screw when adjusting the height of the grinding plate. Therefore, an end grinding device for an air conditioner connecting pipe is needed, which can drive the grinding plate to lift in the vertical direction through a power tool, thereby improving the efficiency when the height of the grinding plate needs to be adjusted to adapt to pipes of different sizes.
