System hardware of bearing cutting automatic production line based on graphic programming

The invention discloses system hardware of a bearing cutting automatic production line based on graphic programming. The system hardware includes an automatic production line scheduling module, a power supply module, a graphic programming interface module and an I/O interface communication module, wherein the power supply module, the graphic programming interface module and the I/O interface communication module are all connected with the automatic production line scheduling module; the automatic production line scheduling module adopts an embedded programmable intelligent chip as a core to execute a control program and achieve the purpose of controlling the whole production line to operate safely and reliably; the graphic programming interface module provides the system with man-machine interaction, and supports the on-line configuration technology; and a user can select display contents and manners according to the need, and can directly access a configuration environment and modify the configuration to enable the modified configuration to take effect directly under the condition of not logging out. The system hardware can solve the defect problem that the bearing production machining control system at present has defects in control precision, functions and price.
