Arrangement for detecting the force between machine parts moved relative to each other

摘要

In the case of known arrangements, prefabricated encapsulated force measuring cells are arranged directly or as a shunt in the force flux to be registered. As a result of a multiplicity of areas which have to be closely tolerant and arranged in terms of construction, these solutions are very costly and space-consuming. Using the arrangement according to the invention, a cost-effective and extremely space-saving solution has been produced. The piezoelectric or piezoresistive converter elements are arranged without a housing directly in a cavity, of blind hole shape, of a machine part, for example the tool holder, through which force flows. This cavity is hermetically sealed by a diaphragm-like force introduction element. The invention is particularly applicable to machines having small-scale active parts, such as tools on crimping presses and the like. <IMAGE>
