摘要
针对激光切割头的喷嘴与复杂曲面工件表面的碰撞,以及高速切割过程中切割头自身与复杂曲面的碰撞,造成切割头损伤或损坏的问题,提出一种切割头防碰自检测保护控制系统。该装系统能够实时监测切割头的碰撞信息,并把碰撞信息发送到激光切割机数控系统中处理后,实现对切割头的控制。实验表明,该自检测保护装置能够防止喷嘴与工件表面发生碰撞,碰撞时数控系统能在0.1 s内做出控制动作,保护切割头,收到良好的效果。
For the collision of nozzle of laser cutting head with complex surface, and the cutting head body collision with com- plex surfacein high-speed cutting process,which cause the problemof cutting head being injuryed or damaged, asystem of anti-colli- sion cutting head withself-protection and control was proposed. It can monitor collision information of the cutting head in real-time. Then, it sent collision information of laser cutting to process in the machine CNC system, achieving control of cutting head. Practice shows that the protecting self-test equipment make nozzle avoid collision from workpiece surface, when the cutting head collision with it, the CNC system can make a control action within the O. 1 s to protect the cutting head, it receives good results.
