The pneumatic grease quantitative filling device includes an air intake control assembly, a gland assembly, an oil storage cylinder, and an oil outlet assembly connected in sequence. The air intake control assembly includes an air booster pump, and one end of the air booster pump There is an air inlet, and the other end is connected to the air circuit control valve. The air circuit control valve is provided with a time relay. The air circuit control valve is also provided with an exhaust port and an air outlet. The exhaust port communicates with atmosphere; the gland assembly includes a gland, a pressure plate and a thrust rod, the gland is fixedly connected to the oil storage cylinder, and the pressure plate can slide on the inner wall of the oil storage cylinder, thereby dividing the oil storage cylinder into an air pressure chamber and a grease There are two parts of the storage chamber, the thrust rod passes through the gland and is fixed on the pressure plate, and the air outlet communicates with the air pressure chamber through the connecting pipe; the lower end of the oil storage cylinder is also provided with an oil outlet, and the oil outlet assembly includes A hose, both ends of the hose are provided with threaded joints, and one end of the hose is connected to the oil outlet.

The gas path control valve is a three-port two-position solenoid valve.

A gasket is also provided at the contact between the gland and the oil storage cylinder.

The gland is fixedly connected to the oil storage cylinder by bolts.

A gasket is provided at the contact between the thrust rod and the gland.

Beneficial technical effects of the utility model: In the utility model, the air circuit is controlled by the time relay and the three-port two-position solenoid valve, and the same gas is injected into the grease storage device at a fixed frequency, and the thrust rod in the device moves every time through the change of the pressure The same displacement, so that the same volume of grease is pressed out of the device and flows out along the preset oil outlet pipe; the air booster pump is used to increase the pressure of the compressed air used by the device to improve the working efficiency of the device; the gland The assembly can be used to seal, maintain gas pressure and provide moving power for the grease; both ends of the hose at the oil outlet use threaded joints, so different oil outlets can be designed according to different working conditions to cooperate with the hose threaded joints, Adapt to various filling operations. The utility model is a semi-automatic grease filling device, which can realize quantitative filling operation for parts and components during mass production, and can cooperate with the device by designing special joints under different working conditions to realize oil filling under various complex working conditions. Grease quantitative filling.
