Abstract

The invention provides a detecting method, device and system for cutting precision of a laser, and relates to the technical field of cutting equipment detection. The method comprises the following steps of: obtaining a preset marking and detecting graph; controlling a marking pin assembly to mark on a detecting board according to the preset marking and detecting graph, thereby forming a marked graph; movably mounting the marking pin assembly on a portal frame of the laser cutter; arranging the detecting plate on a bed body surface of the laser cutter; controlling length of a marking and detecting graph practical feature of a projection detector; and determining cutting precision of the laser cutter according to errors between the length of the practical feature and length of a preset feature of the preset marking and detecting graph. According to the embodiment of the invention, the method avoids the problem that output efficiency of laser cutting equipment is severely affected as mounting and dismounting time for fittings such as a laser head, a laser unit and a water cooler is relatively long; and meanwhile, material cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cutting equipment detection, in particular to a method, device and system for detecting cutting accuracy of a laser cutting machine. Background technique [0002] Laser cutting equipment needs to be inspected for quality and accuracy after installation before delivery, and can only be shipped normally if it passes the inspection. [0003] The existing accuracy detection method is to assemble the bed, gantry, laser head, laser, water cooler and other accessories into a complete laser cutting machine, in which the gantry is set across the bed, and the laser head is installed on the gantry , driven by the motor and the system, the laser head can move in three-dimensional directions, and cut stainless steel or carbon steel plates according to the system's preset graphics. Measure the cut plate, compare the measurement result with the preset graph, if the error exceeds the preset range, correct the laser cutt...
