1. A modular hardness testing machine comprising:
a) a measuring component and a set of frames, wherein the measuring component includes a measuring component housing and a locating slot; b) the measuring component has the locating slot configured to receive a frame, wherein the locating slot allows a user to modularly interchange the frame; c) the measuring component housing encloses a presshead which encloses a load cell having through-holes holding transmission pins, wherein a first end of each transmission pin contacts a displacement measurement sleeve, and wherein a second end contacts a transmission plate; d) a motor mounted to the measuring component housing, wherein the motor is connected to a reduction drive; wherein the reduction drives a lead screw mounted on a bearing mount; and e) a moveable presshead driven by the lead screw, wherein the measuring component includes a circuit housing for the electronics system, wherein the electronics system comprises: a motion control and driver system; a data processing system; a data display system; and a data communication system, wherein the motion control and driver system is configured as a closed-loop digital control system, which generates force to the indenter, wherein the system driver is configured to move the presshead forward or backward, wherein the data processing system calculates and analyzes the hardness according to indentation on the test specimen produced by the indenter, wherein the LCD of the data display system displays test results, wherein the data communication system transfers test results to a PC or printer. |
