Abstract
A modular hardness testing machine has a measuring component and a set of frames. The measuring component includes a housing and locating slot. The measuring component has a locating slot configured to receive a frame. The locating slot allows a user to modularly interchange the frame. The measuring component's housing encloses a presshead, which encloses a load cell having through-holes holding transmission pins. The first end of each transmission pin contacts a displacement measurement sleeve, and a second end contacts a transmission plate. A motor is mounted to the housing. The motor is connected to a reduction drive. The reduction drive reduces speed and drives a lead screw mounted on a bearing mount, and a moveable presshead is driven by the lead screw.
