CNC safety protection of automatic fiber laser cutting machine based on single chip microcomputer

by:Lxshow     2021-05-17

The safety guard circuit of the CNC automatic fiber laser cutting machine based on single-chip microcomputer belongs to safety guard circuit technology. The NC terminals of the HR8828-QFN48 micro-stepping motor drive chip are all grounded, and the HR8828-QFN48 micro-stepping motor is driven. The HOME of the chip experiences a continuous 3.3V power supply by the upper resistance. The three sets of SENSE1 terminals of the HR8828-QFN48 micro-stepping motor drive chip are connected to one end of the resistor RS1, and the other end of the resistor RS1 is grounded. The HR8828-QFN48 micro-stepping The three sets of OUT1B terminals of the motor drive chip are interconnected and connected to each other, and the three sets of OUT2B terminals of the HR8828-QFN48 micro-stepping motor drive chip are interconnected and connected to each other. The three sets of the HR8828-QFN48 micro-stepping motor drive chip The SENSE2 terminal is connected to one end of the resistor RS2, the other end of the resistor RS2 is grounded, and the GND terminal of the HR8828-QFN48 micro-stepping motor driver chip is grounded.

The automatic fiber laser cutting machine for active calibration of the workpiece includes a machine tool, and the top surface of the machine tool is equipped with a sinking rack rack; a splint-type calibration assembly, the splint The self-adjusting assembly is arranged on both sides of the sinker rack, and the splint-type correction assembly is arranged along the length of the machine tool. The splint-type correction assembly includes a telescopically movable correction plate, and two splint-type correction assemblies are The movement direction of the collation plate is compared and toward the middle of the machine tool, and the length of the collation plate and the machine tool are biased in the same direction; and a plate type support mechanism, the plate type support mechanism is arranged between the settlement path of the sinker rack, the plate type support mechanism It is arranged between adjacent racks of a sinking rack rack. This new type of experience has been used to mediate the layout of the machine tool, and the problem that the ancient automatic fiber laser cutting machine cannot be configured to adjust the assembly, and the new type of application can realize the active revision of the workpiece without damaging the appearance of the workpiece. The mastering of the revision process is simple and difficult. speed.
