Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, and particularly relates to a liquid discharging device for an air filling and oil injecting machine. Background Art

[0002] With the continuous development of the shock absorber industry, the production and assembly technologies of shock absorbers are constantly updated and iterated. The air filling and oil injecting of shock absorbers have evolved from the original manual assembly to the current use of air filling and oil injecting machines in the existing technology. The existing air filling and oil injecting machines generally have an oil storage tank, which is connected to an injection cylinder through a pipeline. The injection cylinder is connected to an oil injection valve in an air filling and oil injecting assembly through a pipeline. During production, the cylinder barrel of the shock absorber is hermetically connected to the oil injection channel of the air filling and oil injecting assembly. The injection cylinder extracts the oil from the oil storage tank and then injects it into the cylinder barrel of the shock absorber through the oil injection valve. During production, it is necessary to discharge the air in the injection cylinder and the pipeline to prevent the air from entering the cylinder barrel together with the oil, which will have a negative impact on the damping force of the shock absorber. However, in the existing air filling and oil injecting machines, the oil injection valve is fixedly connected in the oil injection channel. When discharging the air in the injection cylinder and the pipeline, the air and oil are discharged from the oil injection valve, which will pollute the oil injection channel. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a liquid discharging device for an air filling and oil injecting machine, aiming to solve the problem that the air and oil are discharged from the oil injection valve during oil injection in the existing air filling and oil injecting machines, which will pollute the oil injection channel.

[0004] To achieve the above purpose, the utility model discloses a liquid discharging device for an air filling and oil injecting machine, which includes an oil storage tank, an injection cylinder, an oil injection valve, an air and oil discharging valve, and an air filling and oil injecting assembly. The injection cylinder is provided with an oil pumping port and an oil injection port, and the oil pumping port and the oil injection port are respectively connected to the oil storage tank and the air and oil discharging valve; the air and oil discharging valve is connected to the oil injection valve, and an oil injection channel is arranged in the air filling and oil injecting assembly, and the oil injection valve is connected to the oil injection channel.

[0005] Preferably, the oil pumping port and the oil injection port are respectively connected to the oil storage tank and the air and oil discharging valve through an oil pumping pipe and an oil injection pipe.

[0006] Preferably, the air and oil discharging valve is fixedly arranged above the oil injection valve, and the air and oil discharging valve is closely attached to the oil injection valve.

[0007] Preferably, the air and oil discharging valve is connected with an oil and air discharge pipe.

[0008] Preferably, the air and oil discharging valve is a manual switch valve.

[0009] The beneficial effects of the present utility model are as follows: For a liquid discharging device for an air-filled oil injector provided by the above technical solution, before air filling and oil injection, the air and oil discharging valve is opened, the oil injection cylinder extracts the oil in the oil storage tank, the air in the oil injection cylinder and the pipeline is discharged through the air and oil discharging valve, and a part of the oil will also be discharged from the air and oil discharging valve. Then, the air and oil discharging valve is closed, and then the oil injection valve is opened for oil injection; this solves the problem that when the existing air-filled oil injector injects oil, air and oil are discharged from the oil injection valve, which will contaminate the oil injection channel.

The oil injection cylinder 110 is provided with an oil suction port and an oil injection port, and the oil suction port and the oil injection port are respectively communicated with the oil storage tank 100 and the exhaust gas and oil valve 130; the exhaust gas and oil valve 130 is communicated with the oil injection valve 120, and an oil injection channel is arranged in the inflatable oil filling assembly 140, and the oil injection valve 120 is communicated with the oil injection channel. Before inflatable oil filling, the cylinder barrel of the shock absorber is hermetically communicated with the oil injection channel of the inflatable oil filling assembly, the exhaust gas and oil valve 130 is opened, the oil injection cylinder 110 sucks the oil in the oil storage tank 100, the air in the oil injection cylinder 110 and the pipeline is discharged through the exhaust gas and oil valve 130, and a part of the oil will also be discharged from the exhaust gas and oil valve 130. Then the exhaust gas and oil valve 130 is closed, and then the oil injection valve 120 is opened for oil filling; it solves the problem that when the existing inflatable oil filling machine fills oil, air and oil are discharged from the oil injection valve, which will pollute the oil injection channel.

[0017] In one embodiment, the oil suction port and the oil injection port are respectively communicated with the oil storage tank 100 and the exhaust gas and oil valve 130 through an oil suction pipe 160 and an oil injection pipe 170.
