Embodiment Construction
[0023] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.
[0024] The invention discloses a refrigerant filling clamping assembly, which comprises a housing, a clamping piston 1 and a steel ball 4 . The steel ball 4 is installed on the cage 5. The clamping piston 1 is composed of a piston head and a piston rod. A drive chamber 8 is formed between the top of the piston head and the housing. The drive chamber 8 is connected to the pipeline. The other part of the piston head One side is provided with a measuring chamber 7, and the measuring chamber 7 is externally connected with pressure measurement and signal transmission components. A pressure signal sensor and a corresponding data transmission line can be used here to transmit the pressure sensing signal to the control component. The housing referred to here refers to a relatively fixed structure that forms a drive chamber and a measurement chamb...

The invention discloses a filling clamping assembly, a filling gun, a filling device and an automatic clamping recognition method. The filling clamping assembly comprises a shell, a clamping piston and a steel ball; the steel ball is installed on a holder; the clamping piston comprises a piston head; one side of the piston head is a driving cavity; the driving cavity is connected with a pipeline; the other side of the piston head is provided with a measuring chamber; the outside of the measuring chamber is connected with a pressure measuring and signal transmitting component; and under the action of a pressure difference between the driving cavity and the measuring cavity, the inner diameter inclined surface of the clamping piston pushes the steel ball to change the radial position of the retainer where the steel ball is located, so that an air conditioner refrigerant filling port is clamped, and a sealing component in the filling port is compressed. According to the filling clamping assembly, the purpose of two-stroke filling clamping is achieved through different pressure differences of the two cavities according to the requirement for filling of air conditioner refrigerants on a vehicle production line, the structure is simple, and the control reliability is high.
Description
technical field [0001] The invention relates to the technical field of refrigerant filling for automobile air conditioners, in particular to a filling and clamping assembly used for the initial filling of refrigerant in an air conditioner on a vehicle assembly production line, and also includes a refrigerant filling gun of the filling and clamping assembly. The refrigerant filling device includes a refrigerant high-pressure filling gun and a refrigerant low-pressure filling gun, and an automatic clamping identification method for judging whether the refrigerant filling gun and the refrigerant filling port are correctly matched. Background technique [0002] As a vehicle air conditioner, the low-pressure end and high-pressure end of the air conditioner have a filling port (referred to as a low-pressure filling port and a high-pressure filling port respectively). After the filling gun is clamped on the filling port and sealed, the filling gun The thimble pushes away the valve ...
