在使用百分表检测工件时,常需使表针对零。由于百分表架刚性较差,转动滚花圈时,若用力不当或滚花圈过紧,常出现要多次转动滚花圈才能稳定地将表针置于零位。为了提高测量效率,我们利用弹性变形原理制作了一种可微调的百分表架,它具有灵敏度高、稳定性好、使用方便等优点,微调范围可达±1毫米。 In the use of dial indicator testing of the workpiece, often need to make the table for zero. Due to the poor rigidity of the dial indicator, rotating knurled circle, if the force is not properly or too tight knurled wreath, often appear to be many times to roll the knurl to stably placed the needle at zero. In order to improve the measurement efficiency, we use the principle of elastic deformation to produce a finely adjustable dial gauge, which has the advantages of high sensitivity, good stability, easy to use, fine-tuning range of up to ± 1 mm.
