我们用旧游标卡尺改制成一根齿厚游标尺。经与新的齿厚游标尺对比及二年来使用,证明完全符合要求。现将改制方法介绍如下: 1.在旧的游标卡尺中选择二根尺杆(主尺)及游标上刻线仍然清晰,尺杆磨损比较小的尺。首先将二根尺的尺杆截至需要的长度(见图2),并研磨尺杆,使尺杆基面平直(保证基面与刻线的垂直度及其与对边的平行度,允差均不大于0.005毫米)。 2.将作为齿厚尺(长的)的一根上的内量爪截去,其截边平行于尺杆基面,并倒角以便焊接。为了使卡尺适合于测量齿厚及减短齿高量爪,将外量爪磨
We use the old vernier caliper to transform into a thick tooth scale. Comparing with the new tooth thick slide scale and its use for two years, it proves that it fully meets the requirements. Now the restructuring methods are as follows: 1. In the old vernier caliper, select two rulers (main ruler) and the cursor on the ruler is still clear, ruler foot wear smaller ruler. First of all two ruler rod length as long as necessary (see Figure 2), and grinding ruler rod, so that ruler base straight (to ensure that the base and the ruler perpendicularity and its parallelism with the opposite side, allow The difference is not more than 0.005 mm). 2. Cut out the upper internal gauge claw as a gear gauge (long) with its cut-off parallel to the base of the ruler bar and chamfer for welding. In order to make calipers suitable for measuring tooth thickness and reduce the tooth height claw, the outer claw grinding
