2. Numerical control feeding and clamping device (feeding trolley):

The production line adopts CNC trolley for feeding. The CNC feeding device is driven by a gear rack and pinion after being decelerated by a servo motor with accurate positioning. The bed feed port is equipped with a photoelectric through-beam switch. When the work piece is fed, the X-axis reference line of the work piece feeding direction can be quickly found, and the X-axis positioning can be performed based on this, so as to realize the precise positioning of the work piece.

3. Electrical System:

1), Overview:

The electrical control system used in this production line takes PLC programmable controller, motion control module, input/output module, high-speed counting module) as the control core, and is equipped with a higher-level computer, AC servo drive system, and frequency conversion speed regulation system. The system is equipped with 8 CNC axes.

Siemens PLC is used to control the positioning of each CNC axis, work piece detection and drilling and other machine tools. The PLC control system realizes high-speed processing and improves the response speed of the system; the upper computer software is independently developed by our company based on the Windows operating system using VB6.0 development software, which is used to edit and transfer the work piece program, monitor the processing status of the machine tool, and adjust the machine parameters.

2), Main functions and features:

a. The CNC feeding device (feeding trolley) adopts full closed loop control to ensure the feeding accuracy during long-distance feeding; other positioning CNC axes adopt semi-closed loop control to ensure the positioning accuracy and stability of the machine tool.

b. Real-time monitoring function. The system can monitor the status of the machine tool and work progress and other related information in real time. The user can understand the fault information of the machine tool and troubleshoot the fault based on the real-time monitoring.

c. A variety of work piece programming methods. The system can be programmed manually, and the host computer software provides a variety of programming templates, which users can choose according to actual needs; the system can also recognize DXF format data and program automatically.

d. Graphic display function. This function can display information such as the position and aperture of the edited hole on the work piece. The user can check the correctness of the programming through the graphic display function to prevent losses due to programming errors.
