Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting heads, in particular to a laser cutting head adjustment and anti-collision device. Background Technique

[0002] A laser cutting machine emits laser light from a laser. After passing through an optical path system, the laser light is focused into a laser beam with a high power density. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, finally a cut is formed in the material, thus achieving the purpose of cutting. Laser cutting processing uses an invisible beam instead of a traditional mechanical knife, with the characteristics of high precision, fast cutting, not limited by cutting pattern restrictions, automatic layout to save materials, smooth cut, and low processing cost, and will gradually improve or replace traditional metal cutting process equipment.

[0003] Chinese Patent with the authorization announcement number CN218612355U discloses a laser cutting head adjustment and anti-collision device, including a gantry and a laser cutting head. The laser cutting head is installed on the gantry. Two anti-collision plates are installed on the laser cutting head. An adjustment mechanism for adjusting the anti-collision plates is provided on the laser cutting head. An inductor is installed on the laser cutting head. The inductor is electrically connected to the adjustment mechanism. An alarm device is installed on the gantry. The alarm device is electrically connected to the inductor. The utility model can effectively protect the laser cutting head during the movement of the gantry and prevent it from colliding with the workpiece.

[0004] However, when the above solution protects the laser cutting head, the anti-collision plates are semi-circularly arranged. The semi-circular shape may not cover all potential collision areas, and the protection effects at different angles and positions may be inconsistent, affecting the anti-collision effect. And it protects the laser cutting head by controlling the lifting of the gantry. The gantry system itself is heavy, so the lifting operation may require more power support, increasing the load and energy consumption of the system.

By fixedly installing the adjusting motor 2 with the slider 1, it is fixed. The adjusting motor 2 drives the rotating rod 21 to rotate, driving the bracket 3 that is slidably inserted therewith to rotate. Since the bracket 3 is slidably inserted with the slider 1, it is limited, enabling it to move up and down on the slider 1, thereby driving the circular ring frame 5 fixedly installed with the bracket 3 to move up and down, so as to drive the laser cutting head 11 to move up and down.

[0031] To reduce the vibration or impact of the laser cutting head 11 during operation, the outer surface of the rotating rod 21 is slidably inserted into the inner wall of the groove of the bracket 3, and the outer surface of the bracket 3 is slidably inserted into the inner wall of the groove of the slider 1. A spring 31 is fixedly installed on the outer surface of the bracket 3, and one end of the spring 31 is fixedly installed on the outer surface of the slider 1.

The driving gear 41 meshes with the rotating gear 51 to make it rotate, driving the cylindrical pin 62 fixedly installed with the rotating gear 51 to rotate. The cylindrical pin 62 is slidably inserted into the spiral groove 61 formed on the cylinder 6, driving the cylinder 6 to rotate.

[0036] To drive the rotation of the cylinder 6, the outer surface of the ring frame 5 is rotatably connected with the cylinder 6. The inner wall of the cylinder 6 is provided with a spiral groove 61. The outer surface of the rotating gear 51 is fixedly installed with a cylindrical pin 62. The outer surface of the cylindrical pin 62 is slidably inserted into the inner wall of the spiral groove 61.

The cylinder 6 is fixedly installed with the arc-shaped plate 7, and its rotation drives the arc-shaped plate 7 to open and close, so as to fix the laser cutting head 11.

[0037] To monitor and feedback the position and state of the laser cutting head 11, the outer surface of the cylinder 6 is fixedly installed with the outer surface of the arc-shaped plate 7.

Since the cylinder 6 is fixedly installed with the arc-shaped plate 7, the rotation of the cylinder 6 drives the arc-shaped plate 7 to open and close. Since the laser cutting head 11 is fixedly installed with the ring frame 5, the lifting of the ring frame 5 drives the laser cutting head 11 to lift. The sensor 71 monitors and feedbacks the position and state of the laser cutting head 11, so that the system can make timely adjustments or protections.

[0038] By setting up an anti-collision mechanism to protect the laser cutting head 11, the anti-collision motor 4 drives the driving gear 41 to rotate.

[0039] Working principle: When the sensor 71 detects that the laser cutting head 11 is too close to the workpiece, the anti-collision motor 4 fixedly installed on the bracket 3 is started to drive the driving gear 41 to rotate. The driving gear 41 meshes with the rotating gear 51 rotatably connected to the ring frame 5 to drive it to rotate, thereby driving the cylindrical pin 62 fixedly installed with the rotating gear 51 to rotate. The spiral groove 61 provided on the cylinder 6 rotatably connected to the ring frame 5 is slidably inserted with the cylindrical pin 62 to drive it to rotate, so that the arc plate 7 fixedly installed with the cylinder 6 opens and closes to protect the laser cutting head 11 fixedly installed with the ring frame 5;

[0040] At the same time, the adjusting motor 2 fixedly installed on the inner wall of the slider 1 is started to drive the rotating rod 21 to rotate.
