板金件加工切割机喷嘴

Abstract

本实用新型属于喷嘴技术领域，尤其涉及板金件加工切割机喷嘴，包括：喷头，其能够被安装在激光切割机上；镜片，其能够被安装在喷头内并完成对激光的对焦；控制组件，其包括环体，所述镜片放置在环体上，所述环体的位置能够被改变；限位组件，其包括第二板体，所述第二板体能够向镜片施加弹性推力，以此使得镜片紧贴在环体上，本申请通过启动驱动件带动转轴转动，转轴带动偏心轮转动，由于转轴不在偏心轮的圆心处，偏心轮转动时，第一板体到转轴之间的距离会发生变化，此时偏心轮会推动第一板体移动，以此使得第一板体带动环体移动，完成对环体上镜片位置的调整以进行重新对焦，防止对焦在喷嘴边缘，避免喷嘴过热。
