【摘要】 基于激光三角测量原理的激光传感器通过和特殊的机械结构结合,不仅可以直接测试新螺纹的精确几何参数,而且可以对有油腻、灰尘等物部分填充螺纹情况下进行测试,通过计算机处理后得到螺纹参数,可以判断螺纹的轴向损坏情况。系统的满量程线性度优于0. 1%,静态最高分辨力可达到1μm,静态定位测试重复性误差达±5μm,系统测试速度最大为4mm/s。内螺纹直径在30~300mm,长度0~100mm;外螺纹长度无限制。测试数据具有自动采集、统计、判断、存储等功能。更多还原

【Abstract】 The laser sensor which based on laser triangulation measurement combines the special mechanism.It could complete non-contact fine measurement for internal or outside screw thread.It can not only get the precise parameters by direct measure when the thread is new,but also get the parameters by computer processing when the screw thread was covered in part by dust or smeary,and find out the damage of axial direct and wear of radial direct.Linearity of full scope for the system is better than 0.1%,highest resolution reaches to 1μm,repeated position accuracy reaches to ±5μm,measure speed reaches to 4mm/s.Range of diameter for internal screw thread is 30~300mm,length is 0~100mm.Length of outside screw thread is no limit.更多还原
