Multivariable intelligent fuzzy control system of double-end-face grinding machine

Abstract

The invention relates to a multivariable intelligent fuzzy control system of a double-end-face grinding machine. The system comprises a fuzzy intelligent controller, an industrial computer, a temperature detection module, an upper disc pressure control module, an upper disc shaft control module, a lower disc shaft control module, a workpiece turntable shaft control module and a workpiece measurement module. The fuzzy intelligent controller is a software module combination composed of software modules, an input end of the fuzzy intelligent controller is in signal connection with the temperaturedetection module and the workpiece measurement module, an output end of the fuzzy intelligent controller is connected with the upper disc shaft control module, the lower disc shaft control module andthe workpiece rotating disc shaft control module, and the fuzzy intelligent controller is in data information transmission with the industrial computer and the upper disc pressure control module. According to the system, the machining efficiency serves as the core, the fuzzy control theory is introduced, the temperature of a machine tool mechanical system and the rotating speed of each shaft arecomprehensively controlled, and therefore the machining efficiency and machining precision of a machine tool are greatly improved.

Description

Technical field [0001] The invention relates to the field of finishing grinding of machine parts, in particular to a multivariable intelligent fuzzy control system of a double-end grinding machine. Background technique [0002] Double-end surface grinding equipment is mainly used in automobile, bearing, hydraulic, semiconductor, 3C and other industries. A large number of parts need to be double-end surface finishing, which has extremely high requirements for the consistency of the workpiece, surface quality and processing cost. At present, the commonly used pressure control method for double-end face grinding equipment on the market is three manual pressure regulators with three analog pressure gauges, three-stage manual adjustment, open loop operation, no temperature control, and online measurement is also a contact type The independent instrument operation system has not unified and integrated many factors that affect the processing of parts, and has not formed a closed-loop sy...

Problems solved by technology

At present, the commonly used pressure control method for double-end surface grinding equipment on the market is three manual pressure regulating valves with three analog pressure gauges, three-stage manual adjustment, open-loop operation, and no temperature control. Online measurement is also contact type. The independent instrument operation system does not integrate many factors that affect the processing of parts, and does not form a closed-loop system that considers many factors. For different processed parts, the data cannot be archived to participate in the operation, and the requirements for operators are high. The efficiency of parts processing, The quality is difficult to adapt to my country's current status as a powerful country

[0003] With the continuous development and progress of my country's automobile industry, high-speed high-precision bearing industry, and high-power hydraulic industry, there is a huge demand for high-end intelligent double-end surface processing. The development of high-end CNC double-end surface grinding machine tools is imminent. The traditional three-stage visual inspection The open-loop pressure adjustment of the analog pressure gauge is affected by factors such as unstable gas source, external interference, and temperature changes, which affect the precision indicators such as surface finish, parallelism, flatness, and batch height difference of the finished parts; at present, although there are some Digital three- and five-stage pressure setting is adopted, but due to various reasons, it is still in an open-loop state, and factors such as temperature and interference are not considered, and the effect is not good
