Description

激光加工机的激光嘴研磨装置
技术领域
本发明提供一种当在激光加工机的激光嘴上附着异物时，能够通过利用磨削工具等刃具除去异物，可长时间无人运转的装置。
背景技术
以往的激光加工机，在数控装置(NC装置)中登录有根据材质及板厚预定的标准加工条件。
如果根据标准加工条件进行激光加工，则因装在加工激光枪前端上的激光嘴的异常，发生产生粘渣等加工不良。为了维持最佳的加工条件，操作者事先察觉异常，停止机械，查看激光嘴的异常，在确认异常时，需要手动更换激光嘴，或清洁激光嘴，或修正变形，或者变更加工条件的作业。
在下述专利文献1中，公开了具备用于除去附着在激光嘴上的粘渣的刷子。
专利文献1：特开2001-150173号公报
在激光加工中，由于随着加工的进行，加工时的熔融物(飞溅物)因辅助气体的压力等，向加工物的上方飞溅，附着在激光嘴下表面，因此激光嘴下表面和加工物上表面的间隙不固定。
在上述专利文献1中，公开了在控制激光加工工具的Z轴方向的高度位置的仿形控制中，使激光嘴与接触式传感器接触，记忆Z轴坐标。
此外，在上述专利文献1中还公开了，为了除去附着在激光嘴上的粘渣等异物，通过使激光嘴头前端与刷子接触，激光嘴进行圆弧插补运动，除去异物。
发明内容
本发明的目的在于，提供一种以停止激光嘴的状态利用研磨装置研磨激光嘴的装置。
适用本发明的激光加工机，具备底座、配设在底座上并支持工件的托板、沿着底座的纵向的轴线即X轴被移动控制的支柱、支持在支柱上并沿着与X轴正交的Y轴被移动控制的滑鞍、支持在滑鞍上并沿着与X轴和Y轴形成的平面垂直的Z轴被移动控制的加工头。
而且，本发明的激光嘴研磨装置作为基本机构具备熔融物除去装置，利用磨削工具，除去附着在激光加工工具的前端的激光嘴上的熔融物，该激光加工工具安装在加工头上，所述磨削工具是与所述激光嘴的外形相对应的凹形的成形磨石，通过使所述成形磨石旋转，而研磨除去附着在所述激光嘴上的熔融物。
本发明，为了使仿形机能稳定，激光嘴下表面和加工物上表面的间隙一定，因此，不会引起产生粘渣等加工不良，加工稳定，能够长时间无人运转。

由符号1表示整体的激光加工机，具有配设在底座10上的托板(台座)20，用于载置板状的工件W1。在底座10的纵向(长度方向)的延长线上配置托板交换装置12，准备载置有下次加工用的工件W2的托板20a。
在底座10上的两侧沿着纵向安装有一对导轨34，在导轨34上向X轴方向移动自如地装备有支柱30。
支柱30的X轴上的驱动机构，例如，使用线性马达，在设于导轨34上的固定子和设在直动引导件32上的移动子的之间，形成线性马达。
在支柱30上，沿着与X轴正交的Y轴设有导轨44，将滑鞍40移动自如地安装在Y轴上。滑鞍40具备卡合在导轨44上的直动引导件42，在导轨44和直动引导件42的之间形成线性马达。
滑鞍40，在与X轴、Y轴形成的平面垂直的Z轴方向设有导轨，沿着Z轴移动自如地装备加工头50。加工头50具备光学系，用于导入从激光振荡装置72送出的激光。
在加工头50上，交换自如地装备激光加工工具60。用罩90覆盖加工区域，以确保安全。与底座10相邻地配设强电盘70或激光振荡装置72。操作者指示各种驱动的操作盘80，配设在底座10上纵向的端部。在底座10上的接近操作盘80的一方的端部设置激光加工工具的步骤工位100。
图6是从工作台侧看激光加工工具的步骤工位100的主视图，图7是俯视图。
激光加工工具的步骤工位100，具备：工具工位200，其具有激光加工工具的工具更换箱，激光加工工具具有激光枪和激光嘴；激光嘴工位300，其具有激光加工工具的激光嘴更换箱。
图8是激光嘴研磨装置的说明图。
激光嘴研磨装置600，具有加工头610，加工头610旋转驱动成形磨石即加工工具620。加工工具620使用具有与激光嘴65的外形形状对应的加工面622的成形磨石。
如图9所示，通过将装备有附着飞溅物S1的激光嘴65的激光加工头定位在激光嘴研磨装置600上，使激光加工工具整体向Z轴方向降下。使激光嘴研磨装置600的加工工具620旋转，使激光嘴65与该加工面622接触，能够研磨除去附着在激光嘴65上的飞溅物。
图10是表示激光嘴研磨装置的另一例的说明图。
激光嘴研磨装置650，具有在框架652内由螺栓654支持的加工头660。在加工头660内装备马达，在旋转轴662上安装圆筒状磨石670。
采用该圆筒状磨石670的上表面672，研磨除去附着在激光嘴65的下端面上的粘渣等异物。
图11表示激光嘴研磨装置的另一例。
激光嘴65a具备凸缘部65b，有时附着在该凸缘部65b上的飞溅物S1也成为加工不良的原因。
因此，通过使用激光嘴研磨装置650，使圆筒状磨石670的上表面672与激光嘴65a的凸缘部65b接触，除去飞溅物S1。
通过使激光嘴研磨装置650沿着凸缘部65b向箭头R2方向旋转运动，完成飞溅物S1的除去。
另外，在上述实施例中，说明了作为激光嘴的研磨工具采用磨石的例子，但是当然也能够使用超硬工具等适宜的工具。
