Description

加工中心用的工具交换设备
本发明涉及一种用于加工中心的工具交换设备。
一种已知的此类工具交换设备(DE4009537C2)有一工具交换器，它可沿直线导轨在库交换位置与心轴交换位置之间运动。工具交换架带一包括两个夹头的夹紧装置，夹头可绕一轴线在水平位置与垂直位置之间回转。在心轴交换位置，用过的工具从加工机床的工具心轴转交给其中一个夹头，并从第二个夹头上取下一新的工具。除了用于夹头的回转驱动装置以及用于工具交换架的移动驱动装置外，此工具交换设备还需要一个用于打开和闭合夹头的驱动装置。这么多的驱动装置使此设备比较昂贵。在此已知的设备中，在库与工具交换架之间工具必须借助一特殊的操作设备替换。工具的输送，包括通过库准备、转交给操作设备、再交给交换架、输送到心轴交接位置、以及回转夹头，需要如此长的时间，以致超过工具在高速加工中心的使用持续时间。其结果是降低了加工机床的利用率，因为机床必须等待下一个工具。
此外还已知一种带工具库的薄板加工机(DE3701858A1)，它的工具支座环行。工具借助交接装置从工具库装入输送装置或在工具使用后从此输送装置重新取下。输送装置将工具从承接位置输送到加工位置。一旦加工结束，使用后的工具从加工位置移到取出位置，而在此期间一个事先从工具库转交给输送装置的新的工具随输送装置迁移到加工位置。这样一种结构只适用于加工位置固定的机床。此外，这样一种设备不允许很快存取许多不同的全部必须迅速更换的工具。
还已知一种有两个工具心轴的工具交替设备(JP03010736A1)，其中，为每个工具心轴只各配设一个工具固定件。
每个工具固定件必须配备或卸空一个附加的设计为摇杆的交接装置。设计为摇杆的交接装置将工具从循环的工具库取下，或将工具卸在循环的工具库内。
此已知的工具交换设备只能在设有两个工具心轴的情况下使用。借助它不可能实现经济地交换工具，因为一个工具心轴始终未被充分利用。
从此先有技术出发，本发明的目的是创造一种简单的工具交换设备，即使有大量工具位置它也有尽可能短的工具输送时间。
为实现此目的，按本发明提供了这样一种加工中心的工具交换设备，有至少一个其中可夹紧工具的工具心轴，它可沿心轴轴线方向和至少沿一个与之垂直的方向移动，有一个工具库和在一个输送装置上的两个工具固定件，工具固定件可借助输送装置移动到一个位于工具心轴运动范围内的工具交换位置，在其一个固定件中可从工具心轴卸下用过的工具以及由其另一个固定件可被工具心轴取走一新的工具，其特征为：每一个至少设双重的工具固定件装在一个自己的输送装置上；输送装置可彼此独立地在工具交换位置与工具库的工具支座之间往复运动；以及，工具库的工具支座可循环运动。
在工具库准备一个新的工具或接收一个用过的工具的支座与工具交换位置之间只发生简单的运动，用过的工具的运动和新工具的运动可以彼此独立和互相重叠地进行。工具的交换在相近的位置之间节省时间地、在利用机床运动的情况下经济地以及通过工具库运动没有等待时间地实施。
下面借助于附图进一步说明本发明优选的实施形式。其中：
图1工具交换设备示意透视图和示意地表示运动过程；
图2图1所示工具交换设备的部分简化的示意俯视图；
图3按图2的工具交换设备一个输送装置的示意侧视图；
图4图3所示输送装置的示意侧视图和通过工具库的剖面以及表示在工具交换位置的工具心轴。
工具交换设备有一工具库3和一些输送装置4。工具库3有一条封闭的工具支座3a构成的链条，一个图中未表示的驱动装置使其循环运行。在工具库3的工具支座3a内固定导板3c，它们配备有工具1。在图1中工具库3只表示了其中一排设计为盒的工具支座3a，它们在一个与工具心轴2相邻的区域内构成一个直的循环轨段3b。
当选出的工具支座3a处于构成工具交换位置的导轨5与工具输送装置4之间时，链条被驱动装置停止运动。活塞缸单元4b与此选出的工具支座3a的导板3c接合。然后，导板3c可沿双向箭头6的方向被活塞缸单元4b插入导轨5内或从导轨5抽回。两个处于工具交换位置的导板3c中，一个规定用于承接一个处于工具心轴2上在使用中的工具，而另一个带有规定下一次用于加工的工具1。不仅在工具支座3a中的导板3c而且在导板3c中的工具1均可借助于图中未表示的弹簧夹固定在它们的位置上。
工具输送装置4固定在工具库3的一个位置固定的区域的活塞缸单元4b，通过其活塞杆4d与一个表示在图3中的工具固定件4a连接，它在其相对端带一接合元件4c。接合元件4c与导板3c构成可拆式连接。在导板3c中装了一个仅示意表示的工具1，它为了安装在工具心轴2内有一锥杆1a。除锥杆1a外，工具1还制有一楔形环槽1b，导板3c的截锥形接片3d插入环槽中。图3中工具1的虚线位置表示工具输送装置4的工具交换位置。可以看出，在活塞杆4d伸出时不会妨碍工具库3的运行。
图4表示一个新的工具1向加工中心的工具心轴2的交接过程，其中只表示了心轴箱2a。用点划线表示的左边的工具1处于交接位置。右边的工具固定在工具库3的工具支座3a中。工具心轴2沿箭头7的方向一直移动到使心轴2的旋转轴线与短的锥形固定杆1a的轴线对齐。通过心轴2沿箭头方向8下降，短的锥形固定杆1a插入工具心轴2的锥孔内并夹紧在此锥孔内。当工具心轴2沿箭头方向9移回虚线表示的位置时，工具1从导板3c脱出，因为工具只是借助弹性夹固定的。
在图1中用箭头表示工具交换的全部运动过程。链可以沿箭头方向A移动。其中只有一个装有工具1的两块导板3c已经处于工具交换位置。它们可以沿箭头方向B和C在工具交换位置与各自的工具支座3a之间移动。在一个固定在工具心轴2内的工具1加工结束后，心轴盒2a沿箭头D的方向移动，在此过程中工具1归入空的导板3c内。工具心轴2沿箭头E方向的运动使已用过的工具1从工具心轴2脱开。此工具心轴2沿箭头方向F一直移动到准备好的新工具1的上方。通过工具心轴2沿箭头方向G下降，如结合图4已说明的那棒，此新的工具1被工具心轴2承接。箭头H象征将工具1从导板3c取出以及心轴回移以便进行下一个加工过程。卸下的工具1通过导板3c沿箭头B的运动移回工具库3中。现在工具库3可以按节奏将下一个工具1移到取出位置。取走工具1后空出的导板3c停留在其位置上，以便承接现在处于使用中的工具1。因此，为了下一次的工具交换，工具心轴2必须首先移近此导板3c。
