Protection device for cutting head of self-adaptive laser cutting machine

Abstract

The invention discloses a protection device for a cutting head of a self-adaptive laser cutting machine. The protection device comprises an anti-collision assembly; the anti-collision assembly is installed on a bracket, and the cutting head of the cutting machine is further connected to the bracket and can move relative to the bracket in the vertical direction. The anti-collision assembly comprises a connection part, a spring part and universal balls; one end of the connection part is connected with the bracket; the spring part comprises springs and spring pins, the spring pins are connected with the other end of the connection part and connected with one ends of the springs, and the universal balls are connected with the other ends of the springs; the universal balls are closer to a to-be-cut workpiece than the cutting head of the cutting machine in the vertical direction; the springs connected with the universal balls can automatically stretch out and draw back and can be adjusted in a self adaptive mode according to the actual height, and accordingly a steel plate is prevented from colliding with the cutting head. According to the protection device for the cutting head of the self-adaptive laser cutting machine, the cutting head of the cutting machine can be protected, and the problem that the cutting head is damaged due to the fact that the to-be-cut workpiece is tilted is solved.

Description

technical field [0001] The invention relates to the field of laser cutting, in particular to a cutting head protection device of an adaptive laser cutting machine. Background technique [0002] Laser cutting equipment is achieved by the high power density energy of the laser. The cutting head of the laser cutting machine is the key part of cutting, which affects the cutting quality and cutting efficiency. like Figure 5 As shown, the cutting head of the cutting machine is composed of a nozzle 12, a focusing lens and a focusing tracking system (collimating module and focusing module 11) and the like. At present, when cutting steel plates, the cutting head of the cutting machine will collide with the lifted plate, causing the cutting machine to stop; at the same time, consumable parts such as protective lenses and ceramic ring nozzles are consumed. In severe cases, the focusing lens and the focusing tracking system will be damaged, which requires the replacement of the colli...

Problems solved by technology

[0004] However, the activity of the movable protective cover device in this way is inflexible. When the steel plate warpage is large or there is a protrusion on the steel plate, the cutting head of the cutting machine will be stressed, which will easily cause the cutting head of the cutting machine to be deformed or damaged.
