Abstract

本发明涉及一种用于固定紧固夹的工具，该工具具有一对可围绕平行轴线(8)枢转的杠杆，在其端部带有钳头(9)，该钳头(9)可朝彼此移动并作用在所述夹上。为了监测在紧固夹的紧固件与夹紧带的锁定期间出现的力，使用具有相对于所述工具固定的壳体(11)和一对力传递臂(15)的装置。每个力传递臂(15)在一端弹性地铰接至壳体(11)，在另一端具有针对附接至壳体的力传感器(18)的接触表面(17)，并在力传递臂的端部之间具有孔(20)，与杠杆有关的轴线(8)支撑在该孔(20)中。从传感器信号获得的力/时间或力/路径曲线用作紧固件与夹紧带之间的锁定质量的量度。

Description

在用于固定张力夹的工具中进行力监测的装置
背景技术
WO2016/096983A1描述了一种用于固定张力夹的工具，该工具具有可围绕平行轴线枢转的一对杠杆。该杠杆在其端部带有钳口，该钳口可彼此相对移动并作用在张力夹上。钳口通过控制连杆在该处操作，从而它们接合在张力夹的带扣的窗口中，并在带有夹紧带的带扣的变形下锁定。为了安全固定，要施加较大的力。
已经发现，若遵循施加在钳口上的力的给定力/时间或力/路径行为，则能在固定张力夹时实现完美且可再现的结果。
发明内容
本发明的目的是提供一种装置，该装置允许在固定张力夹时检测所述类型的工具中的力的分布，从而检测夹紧带与带扣之间质量不良的连接。
此目的通过一种在用于固定张力夹的工具中进行力监测的装置实现的，该工具具有一对可围绕平行轴线枢转的杠杆，这些杠杆在其端部处带有钳口，该钳口可彼此相对移动并作用在张力夹上。所述装置具有相对于工具固定的壳体，以及一对动力传递臂，每个动力传递臂在一端弹性地铰接至壳体，在另一端具有用于安装在壳体上的力传感器的接触表面，并在其端部之间具有孔，相应的工具杠杆的轴线支撑在该孔中。
从力传感器的信号获得的力/时间或力/路径曲线允许检测在夹紧带和带扣之间的固定不具有期望的质量的张力夹。在这种情况下，例如可更换钳口，以使质量达到期望的水平。
附图说明
下面将参照附图说明本发明的一个实施例。在附图中：
图1是一种用于监测在张力夹固定期间出现的力的装置的等距视图；和
图2和图3示出了图1的装置的部分。
具体实施方式
附图所示的装置具有壳体11，该壳体11基本上由板10组成，该板10可附接至工具7以固定张力夹，该工具仅在图1中示出。这种工具包括一对杠杆，这对杠杆可围绕平行轴线枢转，并在其端部带有钳口，该钳口可彼此相对移动并作用在张力夹上。在图1中，轴线在标记8处示出，而钳口在标记9处示出。
若所述工具是如WO2016/096983A1所述(尤其是在其图9中所示)的工具，则壳体11布置在该工具7的头部之前，并通过穿过孔12的螺栓(未示出)固定到该工具上。
在壳体11中，形成两个动力传递臂15，它们是从板10切出的，并且仅在图1中的下端通过以这种方式形成的弹性接头16与板10连接。每个动力传递臂15在其上端具有针对力传感器18的接触表面17(参见图2)。每个力传感器18经由传感器座19附接至板10，并相对于相应的接触表面17偏置。每个动力传递臂15在其下端和上端之间具有孔20，工具7的相应钳口9的轴线8支撑在该孔20中。在力传感器18安装好之后，每个动力传递臂15的接触表面17平行于形成在壳体11中的相对接触表面22延伸。
为了在操纵错误的情况下防止壳体11过载，动力传递臂15的上端的偏转受到包围端部的支架21的限制。
在板10和工具之间插入有隔板25(图3)，该隔板25具有被轴线8穿过的两个孔26。从隔板25切出两个弹簧腿27，这两个弹簧腿27的自由下端在孔26的区域中承置在轴线8上。
在工具操作期间，安装在轴线8上的钳口9彼此相对移动，以将带扣和张力夹的夹紧带彼此锁定。由此轴线8被压得彼此分开。该力传递到动力传递臂15，而动力传递臂15又作用在力传感器18上。
若从传感器信号确定的力/时间或力/路径曲线从预定行为偏离一定量，则张力夹的带扣与夹紧带之间的连接不符合期望的质量，并且可视为有缺陷。
所述的针对力传感器18的接触表面17的平行排列对于可再现的精确测量很重要。
弹簧腿27也起到提高测量精度的作用。它们试图避免隔板25与轴线8之间的侧隙。
