Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil level detection, in particular to a lubricating oil level detection device. Background Art
[0002] Oiling machine is a device used to inject lubricating oil, grease or other fluids into mechanical equipment, and is widely used in industrial production and maintenance. Its main function is to ensure that mechanical parts are properly lubricated to reduce wear, extend equipment life, and improve work efficiency.
[0003] The pneumatic oiling machine uses compressed air as a power source to press out the lubricating oil stored in the oil tank. The amount of oil remaining in the oil tank is detected by an oil level gauge installed in the oil tank. The oil level gauge detects the liquid level of the remaining lubricating oil in the oil tank, so as to know the amount of remaining oil.
[0004] The traditional oil level gauge uses the buoyancy of the float in the oil to float up, and displays the amount of lubricating oil through the scale. When the above method is used, the following problems will occur when the viscosity of the lubricating oil is high: when the lubricating oil in the oil tank decreases and the oil level drops, the float will be stuck to the inner wall of the oil tank due to the high viscosity of the lubricating oil, and cannot change in real time with the changes in the liquid level of the lubricating oil, resulting in inaccurate liquid level data actually detected by the oil level gauge and poor reliability of the detection results. In addition, the float in the traditional oil level gauge has a physical movement stop point. If the oil volume exceeds the rated liquid level, it can only output the oil volume of the rated liquid level, resulting in the output liquid level data not matching the actual liquid level. Summary of the invention
[0005] The utility model aims to solve the deficiencies in the prior art and provide a lubricating oil level detection device.
[0006] The purpose of the utility model is achieved through the following technical scheme: a lubricating oil level detection device includes a base plate, a movable plate, and a control device. The movable plate is located above the base plate, a weighing sensor is provided between the base plate and the movable plate, the weighing sensor is electrically connected to the control device, and an oiling machine is provided on the movable plate; a sliding bearing is provided on the base plate, a guide shaft matching the sliding bearing is provided at the lower end of the movable plate, a protective cover is provided on the movable plate, and the protective cover is located on the periphery of the oiling machine.
[0007] In the utility model, the oiling machine is placed on a movable plate, and the oiling machine is weighed by a weighing sensor under the movable plate to obtain the weight of the oiling machine. Since the weight of the oiling machine body is known, the remaining oil amount information inside the movable oiling machine can be obtained after the weight of the oiling machine body is subtracted from the detected weight. Compared with the traditional method of obtaining the remaining oil amount by measuring the lubricating oil level height through an oil level gauge, the accuracy of the utility model is greatly improved, and the problem that the oil level gauge is stuck to the inner wall of the oil tank when detecting high-viscosity lubricating oil and cannot accurately measure the oil amount is solved, which effectively improves the accuracy of the detection result. This oil amount detection method in the utility model is not affected by the viscosity of the lubricating oil, and is particularly suitable for high-viscosity lubricating oil. The protective cover plays a certain protective role on the oiling machine, and when the lubricating oil in the oiling machine leaks, the protective cover can effectively prevent the lubricating oil from flowing down the movable plate to ensure the cleanliness of the surrounding environment.
[0008] Preferably, the oil injection machine is a pneumatic oil injection machine.
[0009] Preferably, the weighing sensor is a strain gauge weighing sensor.
[0010] Preferably, three sliding bearings are evenly distributed on the bottom plate.
[0011] Preferably, the protective cover is cylindrical.
[0012] Preferably, when the weight value measured by the weighing sensor is less than a set threshold value, the control device issues an alarm.
[0013] The beneficial effects of the utility model are as follows: compared with the traditional method of obtaining the remaining oil amount by measuring the lubricating oil level height through an oil level gauge, the utility model has greatly improved accuracy, solved the problem that the oil level gauge is stuck to the inner wall of the oil tank when detecting high-viscosity lubricating oil and cannot accurately measure the oil amount, and effectively improved the accuracy of the detection result.

[0021] In the utility model, the oiling machine 1 is placed on the movable plate 3, and the oiling machine 1 is weighed by a weighing sensor under the movable plate 3 to obtain the weight of the oiling machine 1.
