一种动触片硬度检测仪

Abstract

本实用新型公开了一种动触片硬度检测仪，包括硬度检测仪主体、检测头，所述硬度检测仪主体的内侧底部设置有放置辅助机构，所述放置辅助机构包括固定连接在硬度检测仪主体内侧底部的固定座，所述固定座的上端固定连接有放置台，所述放置台的上端固定连接有限定架，所述限定架的内侧滑动连接有滑杆，所述滑杆的下端固定连接有螺纹头。本实用新型所述的一种动触片硬度检测仪，通过将滑杆向下移动，以及使接触块接触到动触片，且滑杆持续向下移动时，便使滑杆压动伸缩杆向内收缩，进而使限位片压缩弹簧，且使接触块向下压紧动触片，达到便于避免动触片发生位移的目的，从而便于检测头对静止状态的动触片进行硬度检测，且提高硬度检测数据的准确性。
