Simulation training platform system for fault detection and maintenance simulation of numerically-controlled machine tool

Abstract

The invention discloses a simulation training platform system for fault detection and maintenance of a numerically-controlled machine tool. An LCD, a standard MDI keyboard, a standard machine tool operation panel, a standard machine tool operation LED lamp emergency stop switch, a key switch and a multiplying power rotary knob are mounted on a numerically-controlled operation and display platform and carry out data communication with an ARM development board through a single-chip microcomputer control circuit in the platform in a serial port mode. The ARM development board carries out data communication with an upper computer through an RJ45 interface. Data processed by all modules of the upper computer are transmitted to the LCD on the ARM development board and LED display lamps on a single-chip microcomputer. By the adoption of an independently developed numerically-controlled operation platform and a numerically-controlled detection and maintenance simulation system, the mutual control between a numerically-controlled system, numerically-controlled electric devices, numerically-controlled circuits, numerically-controlled PMC, a three-dimensional numerically-controlled machine tool, fault setting and troubleshooting can be reflected accurately and truly.

Description

technical field [0001] The numerical control simulation training platform of the present invention particularly relates to a numerical control machine tool failure detection and maintenance simulation training platform system. Background technique [0002] With the wide application of CNC machine tools in the manufacturing industry, the maintenance, repair, testing, upgrading and transformation of CNC machine tools play a vital role in the production of enterprises. The cultivation of such professionals is the focus of vocational education professional construction one. At present, the main forms of CNC maintenance training system include pure software CNC maintenance simulation software system, physical CNC maintenance experiment platform and small teaching CNC machine tools, etc. These three methods have their own shortcomings: [0003] The pure software CNC maintenance system generally only includes the electrical and circuit parts of the simulated CNC machine tool.

AI Technical Summary

Problems solved by technology

[0003] The pure software CNC maintenance system generally only includes the electrical and circuit parts of the simulated CNC machine tool. There are almost no PMC control and parameter setting parts of the CNC system, and the four scenes of the CNC machine tool (NC system, CNC operation panel, machine tool electrical Cabinet, machine tool body) are simultaneously displayed on the display screen of a host computer for operation, control, observation and monitoring. There is no real scene, the user experience is not good, and the training effect is the worst.

[0004] The general problem of the physical CNC maintenance experiment platform is that the investment in equipment is large, the fault setting and maintenance training of precision instruments such as CNC machine tools are required, the operation risks and risks and maintenance costs are relatively large, and the upgrade of the CNC system Relatively fast, real equipment cannot be upgraded and has a high elimination rate

[0005] Small teaching CNC machine tools are simplified small physical CNC machine tools. The common problem is that the training system is single, and the investment and maintenance costs are relatively high.

Moreover, the upgrade of the CNC system is relatively fast, and the real equipment cannot be upgraded and the elimination rate is high.
