Problems solved by technology
[0004] As far as the failure mechanism of the coolant is concerned, there are mainly the following aspects: First, the local high temperature generated by machine tool processing causes high-temperature polymerization of organic molecules in the coolant to form a large number of organic macromolecules, thereby reducing the lubrication effect of the coolant; Yes, the growth of microorganisms and the rapid reproduction of microorganisms will not only affect the lubrication performance of the coolant in the form of impurities, but also produce a large number of macromolecular extracellular secretions and organic acid waves due to their metabolism, which will damage the corrosion inhibition effect of the coolant; in addition In addition, the doping of foreign dust in the environment and the leakage of guide rail oil will also accelerate the failure rate of coolant [2、3]

Embodiment Construction
[0026] The structure and working steps of the device for rapidly monitoring the cooling liquid failure degree of the present invention will be described in further detail below in conjunction with the accompanying drawings:
[0027] The device of the present invention for rapidly monitoring the failure degree of the coolant is controlled by the PCL and operated using the control panel on the top of the device. The whole device is casted by stainless steel, in the shape of a cuboid, hollow inside, with a wall thickness of 3mm. The interior of the device is divided into 5 spaces, the first space is used to arrange the first motor and the second motor, and the second space is used to arrange the third motor. The motor, the third, fourth, and fifth spaces are used to store coolant, the coolant that has just entered is located in the first storage cavity, the coolant being tested is located in the second storage cavity, and the detected coolant is located in the third storage cavity...

Abstract
The invention provides a method and a device for quickly detecting the degree of failure of a coolant. Based on the study of the nature of the failure of the coolant, compared with some existing devices for detecting the failure of the coolant, the method based on the nature of the failure of the coolant, for detecting the degree of failure of the coolant is provided, and the device for detectingthe degree of failure of the coolant is designed. The method can quickly and accurately detect the degree of failure of the coolant while shielding the influence of environmental factors on detectionresults.
Description
technical field [0001] The invention relates to metal cutting detection, in particular to a method and device for quickly detecting the failure degree of cooling fluid. [0002] technical background [0003] Coolant is essential in metal cutting. It plays the role of cooling, lubrication and rust prevention in the process of processing. However, due to the complexity of the processing environment and processing technology, the coolant is prone to failure during use and is difficult to Maintain ideal condition for a long time. The coolant is water-soluble. Once the coolant deteriorates and fails, on the one hand, it will accelerate the wear of the tool, thereby affecting the machining accuracy, and at the same time increase the burden on the machine tool and reduce the service life of the machine tool; on the other hand, due to the lack of effective and fast detection methods or products to provide operators with effective If the information is not identified, the cooling fl...
