[0002] Grinding machines are machine tools that use abrasive tools to grind workpiece surfaces. They come in a wide variety of styles and are simple to operate, making them widely used across various manufacturing industries. Traditional grinders grind products through the rotation of a grinding wheel. The grinding wheel oil tank provides lubrication to the grinding wheel, ensuring that the grinding wheel spindle does not burn out and become damaged due to lack of oil. As a key component of most grinders, the grinding wheel oil tank plays a crucial role. It continuously lubricates the grinding wheel spindle, preventing it from locking and allowing it to continuously drive the grinding wheel for grinding operations.

The utility model discloses an automatic oil replenishing device for the oil tank sensing of the grinding wheel spindle of a grinding machine. An oil level detection device is provided on the oil tank of the grinding wheel spindle, which includes an upper limit sensor for detecting the upper limit of the oil level and a lower limit sensor for detecting the lower limit of the oil level. The upper limit sensor and the lower limit sensor transmit the detected signals to the controller, and the controller responds according to the judgment and performs the next action. An oil replenishing motor is provided on the oil replenishing tank connected to the grinding wheel spindle oil tank. The controller controls the operation of the grinding wheel start-stop contactor and the oil replenishing motor, and can automatically replenish the oil to the grinding wheel spindle oil tank, thereby realizing the function of automatic oil replenishment.
[0024] like Figure 3 The wheel axle 13 of the grinding wheel spindle oil tank automatic oil replenishing device shown in the figure runs through the grinding wheel spindle oil tank 2. The wheel axle of the utility model is completely immersed in the grinding wheel spindle oil tank. The height of the lower limit sensor set on the grinding wheel spindle oil tank is not lower than the height of the wheel axle. This ensures that there is enough oil in the grinding wheel spindle oil tank to lubricate the wheel axle and provide strong protection for the operation of the equipment.
[0025] like Figures 1 to 2 The illustrated automatic oil replenishment device for the grinding wheel spindle oil tank of a grinding machine has a transparent PVC tube 3 connected to the bottom of the grinding wheel spindle oil tank 2. The tube 3 extends vertically upward, and an upper limit sensor 4 and a lower limit sensor 5 are vertically mounted on the tube 3. The upper limit sensor 4 is positioned at the same level as the maximum oil level in the grinding wheel spindle oil tank 2, while the lower limit sensor 5 is positioned at the same level as the minimum oil level in the grinding wheel spindle oil tank 2. A transparent plastic tube extends from the grinding wheel spindle oil tank of the utility model. The tube is made of PVC and a copper coupling and is secured to the front surface of the grinding wheel spindle oil tank via threads and a sealing gasket. Two hydraulic high and low sensors on the tube provide alarms and automatic replenishment of hydraulic oil. The oil in the tube is at the same level as that in the grinding wheel spindle oil tank, allowing for intuitive observation of oil usage within the tank.

The grinding wheel spindle oil tank and the oil replenishment tank of the utility model are connected together by the oil replenishment pipe, and each of the grinding wheel spindle oil tank and the oil replenishment tank is provided with an oil port connected to the oil replenishment pipe.
[0027] like Figures 1 to 2 The shown device is an automatic oil replenishing device for the oil tank of the grinding wheel spindle of a grinding machine. The controller is also connected to an alarm indicator light 10. The alarm indicator light 10 displays a red light when the oil in the oil tank 2 of the grinding wheel spindle is lower than the position of the lower limit sensor 5. The alarm indicator light 10 displays a green light when the oil in the oil tank 2 of the grinding wheel spindle is higher than the lower limit sensor 5 and lower than the position of the upper limit sensor 4. The present invention is also provided with an alarm indicator light. When the oil in the oil tank of the grinding wheel spindle is lower than the set lowest level, the lower limit sensor transmits a signal to the controller. While controlling the operation of the grinding wheel start-stop contactor and the oil replenishing motor, the controller also controls the alarm indicator light to display a red light. When the oil replenishment is completed, the upper limit sensor transmits a signal to the controller. The controller controls the alarm indicator light to change to green. The alarm indicator light indicates the working status of the equipment, which can provide the operator with a more intuitive use experience, facilitate the operator to understand the actual working conditions of the equipment, and make the use of the equipment more humane.
[0028] The utility model discloses an automatic oil replenishing device for the oil tank sensing of the grinding wheel shaft of a grinding machine. When in use, when the oil level detection sensor reaches the lower limit, the grinding wheel start-stop contactor is disconnected, the equipment stops, and then the alarm indicator light turns red to alarm, and at the same time the oil replenishing motor starts to work, and the oil in the oil replenishing tank is transported to the grinding wheel shaft oil tank through the oil replenishing pipe to realize automatic oil replenishment. When the liquid level reaches the upper limit of the oil level detection sensor, the oil replenishing motor stops working, the grinding wheel start-stop contactor is in a normal state, and the indicator light shows green, and the equipment can be operated and started normally.
[0029] The utility model discloses an automatic oil replenishing device for the oil tank sensing of the grinding wheel shaft of the grinding machine, which can automatically detect the oil level in the grinding wheel oil tank of the grinding machine, and automatically replenish the oil when the oil level is lower than the minimum liquid level, without stopping the machine, which does not affect the normal operation of the equipment and does not require workers to check the oil tank regularly, thereby greatly improving work efficiency, reducing the equipment failure rate, and thus reducing the spindle maintenance cost; at the same time, when the oil reaches the liquid level calibration height, the green indicator light of the equipment lights up; when it is lower than the liquid level, the equipment stops, the indicator light turns red, and it prompts to wait for refueling, making the use status of the equipment more intuitive; in addition, the device is suitable for most general-purpose grinding machines, and according to the basic structure and appearance of the grinding wheel oil tank, a transparent oil level detection tube is designed for easier observation to ensure safety and reliability.
