一、概述为了检测气动手工具的实际工作能力,需要在相同条件下对同一类型的机器进行比较。然而,在实地作业时这种比较是较困难的,因为实地作业时机器运转的状态随着操作者施加的轴推力的大小而变化。因此,如不监测到轴推力的变化,则机器之间的可比性极差。为使气动手工具在实地作业时能在某一轴推力的范围内工作,就需要同时测量其施加的轴推力,使轴推力控制在一定的范围内。目前市场上出售的一些力传感器是不适合此种测量的,这主要由于操作者的手与气动工具的手柄之间不应有较大的空隙。而对 I. Overview In order to detect the actual working capability of pneumatic hand tools, it is necessary to compare the same type of machines under the same conditions. However, this comparison is more difficult in field operations because the state of operation of the machine during field operations varies with the amount of axial thrust applied by the operator. Therefore, if the change in shaft thrust is not monitored, the comparability between machines is extremely poor. In order for the pneumatic hand tool to work in a certain range of axial thrust when working in the field, it is necessary to measure the thrust of the shaft applied at the same time so that the thrust of the shaft is controlled within a certain range. Some force sensors currently on the market are not suitable for this kind of measurement, mainly because there should not be a large gap between the operator’s hand and the handle of the pneumatic tool.
