一种塑胶制品检测用数显悬臂梁冲击试验机

Abstract

本实用新型涉及数显悬臂梁冲击试验机技术领域，尤其涉及一种塑胶制品检测用数显悬臂梁冲击试验机，包括有检测台、气缸、限位板和夹紧机构，检测台上安装有气缸，气缸的伸缩杆上安装有限位板，检测台内设置有夹紧机构，还包括有转动杆、固定杆和固定板，检测台内固定连接有固定杆，固定杆上转动式设置有转动杆，转动杆上固定连接有固定板。通过将与被测材料匹配的冲击块卡在转动杆上，并将固定套拧在转动杆转动，随后松开磁板，弹性件随之回弹带动磁板向下移动，磁板上的磁铁与冲击块吸附，以此使得磁板与固定套对冲击块进行限位固定，进而便于根据测试需要更换不同大小的冲击块，从而适应不同的测试标准和材料特性。
