Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, specifically to a zero-swing cutting structure for a laser tube cutting machine. Background Technology

[0002] A laser tube cutting machine is a machine that can cut tubes using a high-power-density laser beam. The focused high-power-density laser beam has a large amount of energy. When the beam irradiates the surface of the workpiece, it can rapidly heat up the material of the irradiated part of the workpiece to melt, vaporize, ablate, or reach the ignition point. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby achieving the cutting and separation of the workpiece.

[0003] Currently, laser tube cutting machines lack a zero-oscillation mechanism. Although the traditional oscillation cutting structure of laser tube cutting machines can precisely control the rotation of the motor, it still has certain errors and is difficult to achieve zero oscillation, resulting in problems such as poor stability, poor cutting accuracy, and low yield. Therefore, a zero-oscillation slitting structure for laser tube cutting machines is proposed to add a zero-oscillation mechanism. Through the combination of gear and rack transmission, linear guide rail and reducer, the stability of oscillation cutting is improved, resulting in high efficiency and high accuracy. It can realize automatic cyclic processing and save cutting time, greatly improving production efficiency. Utility Model Content

[0029] For example, such as Figure 1 , Figure 4 As shown, the present invention also includes the cutting assembly 3, which includes a cam roller turntable 301, and the slide plate 202 is connected to the cam roller turntable 301 by bolts. A swing shaft 302 is mounted on one side of the cam roller turntable 301 by a bearing, and a swing arm 303 is connected to the top of the swing shaft 302 by bolts.

[0030] In use, the cutting head's operating angle can be controlled and adjusted via the cam roller turntable 301, swing shaft 302, and swing arm 303 to adapt to different swing cutting needs.

[0031] For example, such as Figure 2 As shown, the present invention also includes a first guide rail 106 bolted to the surface of the support frame 101, a first slider 107 bolted to both sides of the fixed main board 102, the first slider 107 being slidably connected to the first guide rail 106, a first servo motor 105 bolted to the support frame 101, and the first servo motor 105 being connected to the helical gear 103 via a drive shaft.
