具有分段的射束导向管的激光加工机
摘要：
激光加工机(1)在激光射束源(11)与激光加工头(7)之间具有激光射束导向装置(12)，该激光射束导向装置具有可折的射束导向管(8)。该射束导向管(8)包括三个管段(13，14，15)，这些管段绕着摆动轴(17，19，21，23)可相互相对摆动，这些摆动轴本身横向于激光加工头(7)的运动平面延伸。为了避免射束导向管的、非定义的尤其是不合常规的运行状态设置一装置(24)，借助该装置可在大小上控制在射束源侧管段(13)与中间管段(14)之间的摆动角(α)和/或在加工头侧管段(15)与中间管段(14)之间的摆动角(β)。
摘要（英）：

A laser machining tool (1) comprises a laser beam guide (12) arranged between a laser beam source (11) and a laser machine head (7) and having a foldable beam guide tube (8). The beam guide tube (8) comprises three tube segments (13, 14, 15), which can be pivoted about pivot axes (17, 19, 21, 23) relative to each other, said axes running in the transversal direction of a movement plane of the laser machining head (7). In order to avoid undefined, particularly irregular operating states of the beam guide tube (8), a device (24) is provided with which the pivoting angle (a) between the tube segment (13) on the beam source side and the middle tube segment (14) and/or the pivoting angle (ß) between the tube segment (15) on the machining head side and the middle tube segment (14) can be controlled regarding the size thereof.
