Description

Technical Field

[0001] The utility model relates to the technical field of oil dripping machines, in particular to a high-precision quantitative oil dripping lubrication mechanism. Background Art

[0002] An oil dripper is a mechanical device that lubricates an object by dropping lubricating oil or grease on the surface of the object that needs lubrication. An oil dripper is also called a lubrication device. Mechanical equipment needs regular lubrication. In the past, the main way of lubrication was to perform manual lubrication after a certain maintenance cycle based on the working condition of the equipment, such as grease. At this time, manual lubrication or use of an oil dripper is required to lubricate the equipment. The oil dripper generally has a quantitative control function, which can control the metering of the dropped lubricant.

[0003] The working mode of the oil dripping machine is mainly to use the dead weight of the lubricating oil to drip onto the friction pair drop by drop. This lubrication method is mostly used for friction pairs that are small in number and easy to approach, such as the lubrication of machine tool guides, gears, chains and other parts. The oil dripping lubrication is implemented by equipping the oil supply part with an oil needle valve type oil filling cup. In this way, the lubricating oil can be accurately dripped onto the part that needs lubrication, ensuring the normal operation of the mechanical equipment and extending its service life.

[0004] However, the existing oil dripping machine uses the weight of the lubricating oil to drip onto the friction pair drop by drop. This lubrication method has a slow flow rate of the lubricating oil and a poor lubrication effect. Therefore, it does not meet the existing needs. In this regard, we propose a high-precision quantitative oil dripping lubrication mechanism. Utility Model Content
