由US 2008/0101865 A1已知一种夹持装置,其具有检测夹钳位置的感应式工作的传感器单元。
发明内容
在此背景下,本发明的任务在于,说明一种扩展现有技术、尤其产生更可靠、更精确的开关信号的装置。
该任务通过具有权利要求1的特征的夹紧装置来解决。本发明的有利的构型是从属权利要求的主题。
根据本发明的主题,提供一种夹紧装置,其具有壳体、在壳体中运转的活塞连同活塞杆和至少部分地布置在壳体中的询问单元,其中,询问单元包括至少两个传感器单元。
传感器单元沿着活塞杆的纵轴线相互间隔开地布置并且布置成距所述活塞杆一间距。
活塞、活塞杆以及布置在活塞上或活塞杆上的金属信号发生器是强制性引导的并且可以在第一端部位置和第二端部位置之间运动。
此外,第一传感器单元在平行于纵轴线延伸的方向上布置在信号发生器的第一端部位置处,第二传感器单元在平行于纵轴线延伸的方向上布置在信号发生器的第二端部位置处。
每个传感器单元具有感应式的第一传感器和感应式的第二传感器,所述第一传感器具有第一灵敏度曲线,所述第二传感器具有第二灵敏度曲线。
每个第一传感器和每个第二传感器包括作为振荡器的一部分的感应线圈。
在平行于活塞杆的纵轴线延伸的方向上,第一传感器的感应线圈相对于同一传感器单元的第二传感器的感应线圈具有从线圈中心到线圈中心的第一间距,其中,两个灵敏度曲线部分重叠。
询问单元优选涉及电路板形式的总体能够更换的询问盒,其具有固定元件,固定元件用于固定在夹紧装置(例如肘杆式夹紧装置)的壳体上或至少部分地固定在夹紧装置(例如肘杆式夹紧装置)的壳体中。
优选地,第一传感器的和第二传感器的灵敏度曲线相应或几乎相同或不同。应注意,灵敏度曲线也可以描述为灵敏度范围。相应的灵敏度曲线确定相应的传感器的最大探测有效距离。
可以理解,信号发生器在活塞上或在活塞杆上的布置包括所有的以下布置可能性:所述布置可能性导致,信号发生器与活塞和活塞杆强制性引导地随动(mitbewegen)。
根据本发明的装置的一个优点是,通过根据本发明的传感器进行的位置确定在第一近似中与传感器单元至信号发生器的间距无关。由此,尤其在更换和维修时,尤其在安装在夹紧装置之后进行查询单元的校准成为多余。
另一优点在于,通过对于每个传感器单元或每个开关点分别使用两个传感器,所产生的开关信号基本上与温度无关并且因此更加可靠。
根据本发明的夹紧装置此外使得使用者能够在必要时借助控制单元使开关点移位或匹配于自身的期望/边界条件,而无需物理上的或结构上的设置改变。
根据第一实施方式,信号发生器平行于所述活塞杆的纵轴线具有第一宽度,其中,所述第一宽度分别相应于每个传感器单元的感应线圈之间的第一间距。替代地,所述第一宽度分别相应于所述第一间距的n倍,其中,0.9≤n≤1.1。
在另一种实施方式中,每个传感器具有灵敏度曲线,并且第一间距如此选择,使得一个传感器单元的第一传感器的和第二传感器的灵敏度曲线部分地重叠。
根据第一扩展方案,第一传感器单元和第二传感器单元分别设计用于当以下情况时输出开关信号:所述传感器单元的一个传感器的由所述信号发生器生成的探测信号位于上升沿上并且同一传感器单元的其他传感器的由所述信号发生器生成的探测信号同时位于相应的灵敏度曲线的下降沿上。
替代地或附加地,第一传感器单元和第二传感器单元分别设计用于当以下情况时输出开关信号:所述传感器单元的第一传感器的由所述信号发生器生成的探测信号和同一传感器单元的第二传感器的由所述信号发生器生成的探测信号相应或者除预给定的最大差以外相应,其中,所述探测信号分别大于预给定的最小值。
通过根据两个灵敏度曲线确定开关信号,一方面可以确保非常可靠的开关点。另一方面,各两个所涉及的感应线圈能够实现开关点的简单的个体的匹配。
附图说明
以下参考附图更详细地阐述本发明。在此,类似的部分标有相同的附图标记。所示出的实施方式是显著示意性的,即,间距以及横向和竖直的延伸不是成比例的,除非另有说明,彼此之间也不具有可导出的几何关系。
其中,示出:
图1示出夹紧装置的根据本发明的第一实施方式的示意性视图;
图2示出根据本发明的传感器单元的灵敏度曲线的示意性视图。
具体实施方式
图1的图示意性地示出构造为肘杆式夹紧装置的根据本发明的夹紧装置10。夹紧装置包括壳体12、在壳体12中在第一端部位置E1与第二端部位置E2之间运转的活塞14连同活塞杆16。活塞杆16上的活塞14设计用于在两个端部位置E1和E2实施引导运动,其中,运动方向与活塞杆的纵轴线L重合。
在所示出的实施例中,金属信号发生器18布置在活塞杆16上。信号发生器对于活塞14的第一端部位置E1占据相应的第一端部位置E3并且对于活塞14的第二端部位置E2占据相应的第二端部位置E4。
在壳体12中还布置有第一传感器单元20和第二传感器单元22,其中,这两个传感器单元都构成询问单元24的一部分,询问单元的另外的部分——例如具有分析处理逻辑电路的电路板未示出。
两个传感器单元20和22分别布置成距活塞杆16一间距。第一传感器单元20在活塞杆16的纵轴线方向上布置在信号发生器的第一端部位置E3处,第二传感器单元22布置在信号发生器的第二端部位置E4处,从而两个传感器单元20和22在平行于活塞杆16延伸的方向上彼此间具有间距A。
每个传感器单元20和22分别具有第一传感器26.1或26.2和第二传感器28.1或28.2,其中,每个传感器26.1、26.2、28.1、28.2分别包括感应线圈和振荡器。
一个传感器单元20或22的两个传感器26.1和26.2或28.1和28.2如此布置,使得在平行于活塞杆16的纵轴线L延伸的方向上,第一传感器26.1或28.1的感应线圈相对于同一传感器单元20或22的第二传感器26.2或28.2的感应线圈分别具有从线圈中心到线圈中心的第一间距A1。
在平行于活塞杆16的纵轴线L延伸的方向上,信号发生器18具有相应于第一间距A1的第一宽度B1。
在图2的图中示例性地在信号发生器的位置x上绘出第一传感器26.1或26.2的灵敏度曲线K1和第二传感器28.1和28.2的灵敏度曲线K2。在所示出的实施例中,两个传感器是标准化的,从而两个灵敏度曲线K1和K2具有相同的最大值或相同的变化过程。灵敏度曲线K1和K2的相应的最大值之间的间距相应于传感器的感应线圈之间的第一间距A1。第一间距如此选择,使得两个灵敏度曲线K1和K2重叠。
如所示的那样,如果信号发生器18恰恰位于两个传感器之间的中心,则由灵敏度曲线K1和K2得出,在两个传感器中通过信号发生器18生成的探测信号具有相同的值。这与灵敏度曲线的或探测信号的绝对高度或绝对值无关。因此,信号发生器18的位置明确唯一地与信号发生器和传感器之前的横向间距无关并且因此能够可靠地确定。
