Embodiment Construction

[0007] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0008] See figure 1 , The present invention provides a laser cutting machine 10, which includes a machine table 100, a support 200, and a probe 300. The bracket 200 is arranged on the machine table 100, and the probe 300 is arranged on the bracket 200.

[0009] The machine 100 is provided with two parallel rows of sliding grooves 101, a sliding rod 102, a laser cutting head 103 and an annular sliding groove 104. The two ends of the sliding rod 102 are respectively arranged on the sliding groove 101 and can slide along the sliding groove 101. The laser cutting head 103 is arranged on the sliding rod 102 and can slide on the sliding rod 102. The laser cutting head 103 includes a laser light source (not shown) and a condenser lens (not shown). The laser light source is used to generate a beam of laser light, and the condenser lens is used to perform the laser Foc...

Abstract

The invention relates to a laser cutting machine which comprises a machine table, a bracket and a probe. A laser cutting head is arranged on the machine table, and the laser cutting head is used for emitting laser and can move on the machine table. The laser cutting head comprises a laser light source and a focusing lens. The focusing lens is used for focusing the laser. Both ends of the bracket are respectively connected to the machine table and can swing with the optical axis of the focusing lens as a swinging axis. The probe is arranged on the bracket, and the distance from the laser cutting head to the top end of the probe along the emergence direction of the laser is the focal distance of the focusing lens. The probe is moved by the laser cutting machine provided by the invention to contact the cutting surface of a processing workpiece, and because the distance from the laser cutting head to the top end of the probe along the emergence direction of the laser is the focal distance of the focusing lens, the distance between the cutting surface of the processing workpiece and the laser cutting head is determined, and the laser emitted by the laser cutting machine can be focused on the cutting surface of the processing workpiece.

Description

Technical field [0001] The invention relates to a laser cutting machine. Background technique [0002] Laser has the characteristics of good parallelism and high energy, and is currently often used in the field of cutting processing. The laser cutting machine used today often places a focusing lens in front of the light source system to focus the parallel laser light generated by the light source system into a point. Since the energy of the focus point is extremely high, the focus point is used for cutting processing. When performing laser cutting, the focus of the focusing lens needs to be on the surface to be cut of the processed workpiece, so that the cutting effect is better. The focus of the existing laser cutting machine generally adopts a focusing lens group, and the up and down movement of the focusing lens group is controlled by a stepping motor to control the focusing of the focusing lens group, so that the laser emitted by the laser cutting machine can be focused on t...
