Minimum quantity lubrication system device

Abstract

The invention provides a minimum quantity lubrication system device. The device comprises an air channel system, an air motor, an oil-air driving part and an injection system; through rotation of a main shaft of the air motor, input and output of compressed air are controlled by vent grooves in the main shaft, on one hand, the compressed air is input to the oil-air driving part through the air motor intermittently and regularly, and under the action of the air pressure and springs, pistons located in the oil-air driving part are in circulating reciprocating motion, so that lubricant in an oiltank is input to an oil-air mixed cavity intermittently and regularly; on the other hand, the residual compressed air output by the air motor is input to the oil-air mixed cavity by the air channel system continuously, so that the compressed air is provided for the injection system and oil mist forming. The device has the advantages that the structure is compact, use is simple, a power supply is not needed, the compressed air commonly used in industry is used as a power source and not wasted, and the oil volume and the sizes of oil drops are adjustable, so that supply of minimum quantity lubricant in a general production site or an anti-explosion special environment can be met.

Description

technical field [0001] The invention belongs to the technical field of cutting processing, and in particular relates to a minimal quantity lubrication system device. Background technique [0002] In the field of machinery manufacturing, the cutting fluid used in processing plays an important role in processing efficiency and processing quality. The cutting fluid is not only expensive to use, but also causes serious pollution to the environment. Faced with the requirements of reducing production costs, improving production conditions and sustainable development for environmental protection, and under the pressure of relevant laws, rational use of manufacturing resources, less waste, less environmental pollution, and "green manufacturing" technology that can carry out a virtuous cycle It will surely become the main development trend in the field of manufacturing in the 21st century. [0003] Minimal Quantity Lubrication, MQL technology is to reduce the amount of cutting flui...
