Minimal quantity lubrication (MQL) supply system for processing of outer-cooling type high-speed machine tool and inner-cooling type high-speed machine tool

Abstract

The invention relates to a minimal quantity lubrication (MQL) supply system for processing of an outer-cooling type high-speed machine tool and an inner-cooling type high-speed machine tool, which mainly comprises a cutting oil atomizing chamber, a fine atomizing spray head, an electromagnetic valve A, a filtering pressure-reducing valve, a proportional pressure-reducing valve, a gas flow control valve A, a gas nozzle, an oil quantity control valve, a minitype oil pump, a one-way valve, a primary sedimentation chamber, a secondary sedimentation chamber and a cone-shaped body component, wherein the fine atomizing spray head is arranged at the upper part of an inner cavity of the atomizing chamber; the electromagnetic valve A, the filtering pressure-reducing valve and the fine atomizing spray head are sequentially connected together by gas delivery pipes; the filtering pressure-reducing valve, the proportional pressure-reducing valve, the gas flow control valve A and the gas nozzle are sequentially connected together by gas delivery pipes; the oil quantity control valve, the minitype oil pump and the one-way valve are sequentially connected together by oil pipes; the atomizing chamber is connected with the primary sedimentation chamber by an oil mist connecting pipe A; and the primary sedimentation chamber is connected with the secondary sedimentation chamber by an oil mist connecting pipe B. The MQL supply system is used for lubricating and cooling a processing area in mechanical processing.

Description

technical field [0001] The invention relates to a system capable of generating fine oil mist, which can ensure that the oil mist can overcome the influence of centrifugal force, and smoothly pass through the high-speed rotating spindle and the inner hole of the tool to reach the processing area, and can also be used for the lubrication and cooling of externally cooled tools. The invention belongs to the technical field of high-speed and high-efficiency green cutting in mechanical processing. Background technique [0002] At present, the environment, resources, and population have become the three major problems facing the world. The deterioration of the global environment is increasing day by day, which is posing a serious threat to the survival and development of human society. In the process of transforming manufacturing resources into products, the manufacturing industry produces a large amount of waste, which forms the main source of pollution to the environment by the m...

Problems solved by technology

[0011] The technical problem to be solved by the present invention is: to overcome the technical existing problems of the above micro-lubrication devices, and to design a micro-quantity lubrication supply system that can generate fine dry oil mist, and this system can ensure that the oil mist can overcome the influence of centrifugal force and pass smoothly. The high-speed rotating spindle inner hole and tool inner hole reach the processing area, and become wet oil mist to lubricate and cool the processing area; in addition, the same minimum quantity lubrication supply system is realized at the same time to adjust and control the air volume and oil mist for different internal cooling tools Optimum lubrication and cooling; moreover, the same minimum quantity lubrication supply system can effectively lubricate and cool both internally and externally cooled tools
