一种IPB螺杆螺纹中径测量检具

,具体涉及一种IPB螺杆螺纹中径测量检具。
技术介绍
螺纹测量有单项测量和综合测量两种方法。单项测量常用于测量螺纹的中径、螺距和牙形半角等参数。常用的圆柱螺纹中径测量方法有:①用螺纹千分尺测量。②把3个具有相同直径的圆柱体──三针,放在螺纹牙槽中然后根据精度要求用千分尺、比较仪或测长仪(见测长机)测出Μ值,计算后即可得出被测螺纹中径值d1。③在工具显微镜上用影象法测量。④在工具显微镜上用轴切法测量。⑤综合测量是检验螺纹的实际中径误差和折算中径误差来控制螺纹的旋合质量。折算中径误差是把螺距和牙形半角等的误差折算在中径方向上的误差。目前国际上比较先进的测量方法为螺纹指示量规测量法,这种方法将螺纹测量分为单一中径测量及作用中径测量。这种方法可测螺纹中径、圆度、螺距、牙型角、锥度,并且通过增加测头可对端面或螺纹的跳动进行测量。单一中径即为单牙中径,作用中径即为全牙中径,若测得单一中径与作用中径数值相同,则表明螺纹各项参数均合格。若两数据不同,则表明螺纹存在问题,具体出现了什么问题,需要进一步的分析判断。现阶段对螺杆螺纹中径测量采用三个芯棒的检具,由于1只手拿三个芯棒不方便,对测量者的技能要求非常高,对中径的计算、芯棒中径的选择均困难,且误差大。采用游标卡尺和千分尺测量螺纹中径时,都存在读取数值误差,精确度低,影响产品装配尺寸精度。
