从日常千分尺的使用中知道,千分尺棘轮的测力大小对于测量的准确性起着一定的作用,尤其对于容易变形的材料更加显著. 过去,由于测力检具只凭经验手感试验,这样往往因测力不准确而影响工作.后来我们做了个简单的工具(如图),经过使用效果很好.它由上套筒1,下套筒2和弹簧5组成,上套筒的球形接触 From the use of daily micrometer to know that the micrometer ratchet force measurement size for measurement accuracy plays a role, especially for easily deformed material is more significant.In the past, because the force gauge with only experienced test feel, so often due to Force measurement is not accurate and affect the work. Later, we made a simple tool (Figure), after the use of good results. It consists of the upper sleeve 1, the lower sleeve 2 and the spring 5, the sleeve of the spherical contact
