Fiber laser cutting machine tracking system
The fiber laser cutting machine furnace has a host computer. We install a PCMCIA card on the TSX SCY 21600 communication module. The PCMCIA card uses a TSX SCP 114 card. It is suitable for UNI-TEL WAY, JB BUS/MODBUS and CHARACTER mode on RS 232-D, current loop or RS 422/RS 485 link. TSX PREMIUM PLC accesses the network, bus and communication link through the PCMCIA communication card. The communication method adopts: the start bit is 1. The data length is 8, and the stop bit is 1. Even parity. The baud rate is 9600bps. The wiring is shown in Table 4. The communication card adopts the RS 485 communication port, which is connected to the standard RS 232 port COM 2 of the host computer through the Adam conversion interface ADAM 4520. The Adam conversion interface ADAM 4520 can realize the conversion from RS 422 (485) to RS 232.
The machine tool uses laser as the tool, and processes the slit into a trapezoidal slit through the focusing characteristics of the focusing lens. The optical head has a Z-axis tracking system to ensure uniform slitting, meeting slit width and roughness, and no sticking in the slit. Slag, no slag blocking and other requirements. 3. The main structural feature of the machine tool is to reduce the speed of the synchronous belt and drive the high-precision pre-loaded ball screw pair to rotate to realize linear movement. The guide rails adopt linear rolling guide pairs. The linear rolling guides are caused by static and dynamic friction due to X (axis), Y ( Axis), Z (axis) adopt IF K 6 Siemens AC servo motor. The difference in the number of passes is very small, and it can move flexibly. The operation accuracy is high. Xi (shaft) transmission adopts IF K 6 Siemens AC servo motor through double gears without backlash transmission to drive the movement of the worktable to realize the conveying of the workpiece: the guide rail adopts a plastic composite guide rail. It has good vibration damping performance; the rotary motion A axis is driven by HFK 6 AC servo motor automatic indexing; The workpiece is supported by the handwheel rotating the left and right trapezoidal screws to adjust the distance between the left and right brackets to center the workpiece.
