Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation, and in particular to an industrial automation control method and system based on wireless remote processing. Background Art

[0002] The creeping phenomenon of CNC machine tool slide refers to the slight vibration when the machine tool slide is running at low speed. This phenomenon usually leads to unstable tool operation, reduced machining accuracy and shortened machine tool life. The main reason for this phenomenon is that the lubricating oil layer on the contact surface of the sliding parts is too thin, resulting in increased friction.

[0003] At present, for highly automated three-axis CNC machine tools with slides in the three directions of XYZ, the traditional method of stopping the machine to add lubricating oil to the slide guide groove is still used to deal with the creeping phenomenon, which cannot adapt to automated mass production, or pre-set a higher feed speed, but this will lead to increased tool friction, thereby reducing the tool life, and the creeping phenomenon of each CNC machine tool occurs at different times, and the existing technology cannot achieve unified processing. Therefore, it is necessary to design an industrial automation control method and system based on wireless remote processing with high efficiency. Summary of the invention

[0006] According to the above technical solution, the vibration increase detection module includes a vibration amplitude sensor, a vibration increase analysis module, a timing module, a lubricating oil filling flow rate detection module, and a feed speed detection module. The vibration amplitude sensor is used to detect the vibration amplitude of a single slide, the vibration increase analysis module is used to analyze the vibration amplitude to determine whether speed adjustment and suspension of work are required, the timing module is used to calculate the vibration increase time and suspension time of the CNC machine tool, the lubricating oil filling flow rate detection module is used to measure the lubricating oil filling flow rate of the slide in real time, and the feed speed detection module is used to measure the feed speed of the slide in real time; The speed regulation module includes an electronic speed regulating valve, a screw motor, a speed calculation module, a pause work judgment module, an oil suction pump, a balance speed calculation module, and an oil layer thickness detection unit. The electronic speed regulating valve is used to adjust the lubricating oil filling flow rate by adjusting the lubricating oil distributed to each slide. The screw motor adjusts the feed speed by adjusting the size of the screw motor rotation speed of each slide. The speed calculation module is used to calculate what kind of lubricating oil filling flow rate and feed speed the slide needs to work at this time according to different needs. The pause work judgment module is used to judge whether it is necessary to pause the work according to the increase in vibration of the slide. The oil layer thickness detection unit is used to detect the difference in oil layer thickness between slides. The oil suction pump reduces the lubricating oil thickness by extracting the lubricating oil from the guide rail of the slide with high oil layer thickness. The balance speed calculation module is used to determine the extraction speed of the slide with high oil layer thickness when balancing the lubricating oil thickness.

Install a vibration amplitude sensor on each slide to ensure that the vibration amplitude changes of each slide can be accurately measured; S2. When the slide table of the CNC machine tool performs feeding motion, the vibration amplitude data collected by the vibration amplitude sensor is transmitted to the vibration enhancement analysis module; S3, judging the vibration increase of each slide, if the vibration amplitude of a slide is higher than the set threshold, it is necessary to increase its feed speed and increase the lubricating oil filling flow rate to reduce the vibration amplitude; S4. Flexible adjustment of whether to suspend work is made according to the vibration increase of each slide. For slides whose vibration increase time exceeds the set time, the suspension time is activated to promote lubricating oil filling and staff inspection; S5. When the oil thickness of a slide is too high due to the high flow rate of lubricating oil filling, cut off the power supply of the oil pump to prevent overflow. When a slide completes a certain processing procedure before other CNC machine tools due to high feed speed, appropriately reduce the feed speed of other slides of this CNC machine tool to prevent inconsistent work efficiency.

[0008] According to the above technical solution, in the above S3, the specific method of increasing the feeding speed and the lubricating oil filling flow rate to reduce the vibration amplitude is: S3-1, when adjusting the oil layer thickness of the machining gap, if the vibration amplitude of a certain slide is detected to reach the oil layer thickness adjustment vibration amplitude threshold When the lubricating oil flow rate of the slide rail is adjusted, the electronic speed regulating valve is used to adjust the lubricating oil flow rate of the slide rail, thereby increasing the lubricating oil filling flow rate of the slide rail. ; S3-2: During processing, if the vibration amplitude of a slide is detected to reach the feed speed adjustment vibration amplitude threshold, When adjusting the speed of the screw motor connected to the slide, the translation speed is adjusted to increase the feed speed of the slide. .
