Description

夹紧装置
技术领域
本发明涉及一种夹紧装置。
背景技术
开头提高的类型的夹紧装置根据DE 202 09 237 U1被公知。该夹紧装置包括一能线性运动的、能由一驱动装置(典型是一气动缸)操纵的调节机构，所述调节机构构造得通过一肘杆机构与一能摆动地受支承的夹紧元件(也称作夹紧臂)作用连接并且所述调节机构一方面具有一驱动侧适配件并且另一方面具有一肘杆侧适配件，其中，这些适配件为了确定所述夹紧元件的打开角度而通过一互相指向的齿部和一夹紧螺钉构造得能相对彼此调节。
发明内容
本发明的任务是改善开头提到的类型的夹紧装置。
该任务利用开头提到类型的夹紧装置通过在本发明实施的特征来解决。根据本发明的夹紧装置包括：一能线性运动的、能由一驱动装置操纵的调节机构，所述调节机构构造得通过一肘杆机构与一能摆动地受支承的夹紧元件作用连接并且所述调节机构一方面具有一驱动侧适配件并且另一方面具有一肘杆侧适配件，其中，驱动侧适配件和肘杆侧适配件为了确定所述夹紧元件的打开角度而构造得能相对彼此调节，驱动侧适配件和肘杆侧适配件中的一个适配件具有一沿调节方向延伸的、经成型的棒并且驱动侧适配件和肘杆侧适配件中的另一适配件具有一用于接收所述棒的插入区域，其中，为了使驱动侧适配件和肘杆侧适配件相对彼此位态确定而设置有一不仅相对所述棒而且相对所述插入区域能夹紧的固定元件；其特征在于，设置有一调节元件，用于横向于调节机构的主轴向方向并且相对具有齿部的所述棒移动具有齿部的所述固定元件。
根据本发明因此设置：驱动侧适配件和肘杆侧适配件中的一个适配件具有一沿调节方向延伸的、经成型的棒并且另一适配件具有一用于接收所述棒的中空空间式的插入区域，其中，为了使驱动侧适配件和肘杆侧适配件相对彼此位态确定而设置有一不仅相对所述经成型的棒而且相对所述插入区域能夹紧的固定元件。
换句话说，根据本发明的解决方案的特征在于：所述一个适配件构造得能插入和能位态固定地到所述另一适配件中或所述另一适配件上的一中空空间中。该标准导致两个高负载的构件中的整体上更好的力分配，结合了打开角度的改善的可调整性，这随后还要更详细地阐释。
附图说明
根据本发明的夹紧装置随后根据两个实施例的附图来详细阐释。
其中：
图1在截面图中示出了具有根据本发明构造的适配件的夹紧装置；
图2在单独图和侧视图中示出了根据图1的适配件；
图3在单独图和截面图中示出了根据图1的适配件；和
图4在截面图中示出了根据本发明的夹紧装置的另一实施方式，其中，棒在肘杆侧适配件上并且插入区域在驱动侧适配件上。
具体实施方式
在图1或图4中示出的夹紧装置包括一能线性运动的、能由一驱动装置1(具有活塞和活塞杆的气动驱动装置或液压驱动装置)操纵的调节机构2，该调节机构直接与该驱动装置1的活塞杆连接并且构造得通过一肘杆机构与一能摆动地受支承的夹紧元件3(优选一所谓的夹紧臂)作用连接。更准确观察地如下设置：构造肘杆侧适配件2.2或2.1关节式地与接片14连接，该接片14又关节式地与杠杆臂15连接并且该杠杆臂15抗转动地与夹紧元件3的摆动轴16连接。此外，所述调节机构2一方面具有一驱动侧适配件并且另一方面具有一肘杆侧适配件2.1、2.2，其中，它们相对彼此能调节地构造用于确定所述夹紧元件3的打开角度。
也参考图2、3和4，对于根据本发明的夹紧装置目前重要的是：这些适配件中的一个适配件2.1具有一沿调节方向延伸的、经成型的棒4并且另一适配件2.2具有一至少部分围住所述棒4的插入区域5，用于接收所述棒4或用于完全围住所述棒4，其中，为了将这些适配件2.1、2.2相对彼此位态确定而设置有一不仅相对经成型的棒4而且相对插入区域5能夹紧的固定元件6。
在此特别优选地设置：所述固定元件6构造为具有一内壁部和一外壁部的由所述棒4贯穿的环，其中，所述内壁部具有一形状锁合地适于所述经成型的棒4的成型部7并且所述外壁部具有多个、优选四个至八个平的表面8。在此特别优选地，所述固定元件6螺母状或者说以螺母的形式构造并且此外构造得完全围住所述经成型的棒4，其中，所述内壁的成型部7和棒4的成型部此外特别优选地构造为无坡度内螺纹。“无坡度”在此被理解为具有坡度“零”的螺纹，本身因此没有真正的螺纹，而是仅理解为一种齿部，其视觉上与螺纹相似。
为了以简单的方式相对彼此能够确定所述两个适配件2.1、2.2的位态，此外优选设置：所述棒4在其成型部的区域中的直径构造得始终小于由所述固定元件6的内壁部限定的直径。在此，所述固定元件6此外在根据图1至图3的实施方式中布置在所述肘杆侧适配件2.2上的一推入开口9中并且在该推入开口中布置得被防止沿所述调节机构2的主轴向方向移动。在根据图4的实施方式中，所述固定元件6布置在所述驱动侧适配件2.2上的推入开口中。所述固定元件6由此基于所提到的两个直径虽然构造得横向地能移动或能调节，但是构造得不沿着所述棒4能移动或能调节。
此外进一步优选地，在所述肘杆侧(图1至3)或在驱动侧(图4)适配件2.2上设置有一调节元件10，用于横向于所述调节机构2的主轴向方向并且相对所述经成型的棒4移动所述固定元件6。在此，所述调节元件10构造为在一设置在所述适配件2.2上的、横向于所述棒4定向的螺纹11中被导向的螺钉、尤其是埋头螺钉。此外，在所述夹紧装置的壳体17上设置有在需要时(借助于盖元件)能封闭的开口，用于从所述夹紧装置之外操纵所述调节元件10。
如由DE 10 2009 054 153 A1公知的那样，此外在每个适配件2.1、2.2上设置有一终端位置发送器12、13。这些终端位置发送器12、13与相应的传感器一起工作，所述传感器用于检测所述夹紧臂的调节位置。特别优选地在该根据本发明的解决方案中设置(见图1至图3)：所述固定元件6布置在两个终端位置发送器12、13之间和/或布置在所述肘杆侧适配件2.2的终端位置发送器13上。
所述根据本发明的夹紧装置的调节如下地起作用：
观察的出发点是相对彼此固定的适配件2.1、2.2。为了改变所述夹紧元件3的打开角度，首先将盖从所述开口移除。然后利用六角扳手松开优选构造为内六角的、以它的操纵侧朝开口定向的埋头螺钉(调节元件10)。这引起：固定元件6的成型部从所述棒4的成型部脱开，两个适配件2.1、2.2现在可以沿纵向方向相对彼此调节。如果找到预期的位置，那么通过拧紧调节元件10又相对棒4夹紧所述固定元件6，从而使得两个适配件2.1、2.2又相对彼此固定。最后还将遮盖装置又插入到所述开口中并结束所述开口角度的调节。
