Z-axis capacitance increasing system of laser cutting machine

Abstract

The invention provides a Z-axis capacitance increasing system of a laser cutting machine. The Z-axis capacitance increasing system comprises a Z-axis capacitance increasing controller U4, wherein the controlled end of the Z-axis capacitance increasing controller U4 is connected with a controlled input circuit. The controlled input circuit receives control signals output by an output control circuit in a numerical control system of the laser cutting machine, so that the Z-axis capacitance increasing controller U4 works in an automatic state or a manual state. The output end of the Z-axis capacitance increasing controller U4 is directly connected with a cutting torch lifting motor M3. The input end of the Z-axis capacitance increasing controller U4 is connected with a limited input circuit and used for inputting an upper limiting signal of a cutting torch and a lower limiting signal of the cutting torch to the Z-axis capacitance increasing controller U4 through the limited input circuit. The cutting torch lifting motor M3 is a direct-current motor with a reduction gearbox. According to the laser cutting machine Z-axis capacitance increasing system, more pulse line control is omitted, and the laser cutting machine Z-axis capacitance increasing system is simple in control line, can not be easily interfered and is high in hardware stability, high in reliability and capable of wholly and greatly improving stability of a machine tool of the laser cutting machine.

Description

technical field [0001] The invention relates to a laser cutting machine, in particular to a Z-axis capacitance height adjustment system in a YAG laser cutting machine.

Problems solved by technology

[0003] The Z-axis capacitor height adjustment system is an important part of the YAG laser cutting machine. The existing Z-axis capacitor height adjustment system generally adopts the servo motor type Z-axis capacitor height adjustment system, and the servo motor type Z-axis capacitor height adjustment system mainly It is composed of a capacitor height adjustment controller, a servo controller, and a servo motor. The biggest problem with this servo motor type Z-axis capacitor height adjustment system is that there are many control lines, and the servo controller is easily affected by interference signals when the lines are long. Servo control The stability of the laser cutting machine leads to the phenomenon that during the cutting process, the tracking height of the laser cutting machine cutting torch fluctuates up and down, and the quality of the cut product is not good, because in order to make the cutting quality of the laser cutting machine good, it is required High stability of torch cutting tracking

Because the servo controller and servo motor are used, the hardware cost is also very high, and there is no advantage in market competition
