Workpieces hardness testing device, has penetrating body with impact surface provided above weight body with predetermined tolerance, where weight body has contact surface cooperating with impact surface

摘要

The device has a vertically moving penetrating body (15) with predetermined mass cooperating with a force sensor i.e. bending support, and an optical detection device detecting and evaluating impressions caused by the penetrating body in workpieces. The penetrating body has an impact surface (16) provided above a weight body (17) with a predetermined tolerance. The weight body has a contact surface (18) cooperating with the impact surface. Another weight body (20) is arranged above the weight body with predetermined tolerance. The force sensor is impinged by the weight bodies.
