[0016] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 2 As shown, a speed-controlled and quantity-controlled oiling device comprises a base consisting of a horizontal bottom plate and a vertical side plate, a servo motor is arranged on the bottom plate, an output end of the servo motor is connected to a driving wheel, a driven wheel is arranged on the side plate, the driving wheel and the driven wheel are connected by a belt, a screw connected to the driven wheel is arranged on the side plate, a driving connecting piece is threadedly connected to the screw, a matching slide rail slider assembly is arranged on the inner side of the servo motor on the bottom plate, the driving connecting piece is connected to the slider, the slider is connected to a cavity telescopic rod and the movement of the slider pushes the cavity telescopic rod to move in the cavity, the other end of the cavity is connected to an oiling cylinder with a cavity arranged therein, and a side end of the oiling cylinder is connected to an oiling pump with an oil inlet valve.

[0018] The oil injection cylinder is provided with a cavity and three ports, all of which are connected to the cavity, one of which is connected to the cavity, one end is connected to the oil injection pump, and one end is connected to the oil receiving component. Furthermore, the port connected to the cavity and the port connected to the oil receiving component are coaxial with the cavity, and the cavity telescopic rod can push and pull in the cavity.

[0019] Wherein, a pair of bearing seats are arranged on the side plate, and the two ends of the screw rod are rotatably connected to the bearing seats through bearings respectively.

[0020] Preferably, a sealing ring is sleeved on one end of the cavity telescopic rod connected to the oil filling cylinder to prevent oil leakage during the pulling and pulling of the cylinder. The other end of the cavity telescopic rod extends out of the cavity and is connected to the slider. The pushing and pulling of the cavity telescopic rod is controlled by the movement of the slider.

[0021] A one-way oil inlet valve is arranged in the oil filling pump to ensure that the oil filling pump can only fill oil into the oil filling cylinder, and the oil filling cylinder cannot return oil to the oil filling pump, and the valve is automatically closed after being filled.

[0022] During operation, the servo motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the belt. Correspondingly, the screw rotates, driving the driving connecting part to move. The movement of the driving connecting part pushes the cavity telescopic rod to push the oil, and the pulling action can cooperate with the oil filling pump to fill the oil into the oil filling cylinder. The speed and amount of oil discharge are controlled by the servo motor.

[0023] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
