[0002] Refrigerant is the medium substance used to complete energy conversion in various heat engines. These substances usually increase power through reversible phase changes (such as gas-liquid phase change). When a general steam engine is working, the thermal energy of steam is released and converted into mechanical energy to generate motive force, while the refrigerant of the refrigerator is used to transfer heat from low temperature to high temperature. Refrigerant usually needs to be filled in steel cylinders for storage and use. In order to improve the filling efficiency of the refrigerant, a refrigerant filling cylinder positioning mechanism is often used.

[0003] The prior art discloses a steel cylinder positioning device and a refrigerant filling machine with the publication number CN216887482U, which is intended to provide a positioning device and a filling machine for a refrigerant filling machine that can accurately position the refrigerant steel cylinder and is conducive to improving production efficiency. The positioning device includes a side positioning mechanism, and a top positioning piece is installed on the frame at a position corresponding to the steel cylinder cut-off door handle, and a positioning groove corresponding to the cut-off door wrench is provided at the lower end of the top positioning piece. A lifting bracket is installed on the frame, and the lifting bracket is connected to the first lifting drive mechanism; the top positioning piece cooperates with the side positioning mechanism and the lifting bracket to realize the positioning of the steel cylinder. The positioning device is provided with a top positioning piece at the top based on the characteristic that the distance between the top surface and the center line of the cut-off door is constant when the cut-off door is closed. The positioning device has high positioning accuracy and can ensure the smooth progress of the filling production, thereby improving production efficiency.

Installing and using multiple drive mechanisms will greatly increase the manufacturing cost of the device and the power consumption during use, thereby increasing the refrigerant filling cost, and the practicality is relatively general.
