Full-automatic detection device of Shore durometer and method thereof

Abstract

The invention discloses a full-automatic detection device of a Shore durometer and a method thereof. The device comprises a working platform, a force measurement mechanism, a CCD measurement system, a detected Shore durometer, a durometer clamping mechanism, a servo motor, a drive control and data acquisition system and a PC machine, wherein the PC machine drives the servo motor to drive the durometer clamping mechanism to move down via a screw rod; meanwhile, output signals of the force measurement mechanism are also simultaneously transmitted to the drive control and data acquisition system, so that the closed-loop control of the whole action is implemented. The device is capable of quickly and reliably mounting various durometers different in shape and size; a servo motor closed-loop control system can be used for slowly enabling a pressing pin of the detected Shore durometer to act on the force measurement mechanism; the PC machine is used for collecting the output signals of a force sensor; the output signals of the force sensor are used as standards; the CCD measurement system is used for automatically collecting indicating values of the Shore durometer and applying measurement results to calculation of error of the indicating values, so that the full-automatic detection of the Shore durometer is implemented.

Description

technical field [0001] The invention relates to the field of hardness tester verification, in particular to a Shore hardness tester verification device, which can meet the needs of measurement departments and related enterprises and institutions for accurate verification of the Shore hardness tester. Background technique [0002] The Shore hardness tester verification device is used for verification (calibration) of various Shore hardness testers, and has been widely used at home and abroad. The main problems of the traditional Shore hardness testing device are: [0003] 1. The function is single, the operation is cumbersome, and the verification efficiency is low; [0004] 2. The clamping fixture of the existing device has limitations, and cannot meet the clamping requirements of Shore hardness testers with different appearance sizes; [0005] 3. Most of the existing verification devices are simple mechanical structures, which cannot realize the functions of automatic ver...
