我们自制了一把既有角尺中心规性能,又有圆规和高度游标卡尺部分性能的划线工具。经一年多时间的使用,效果较好。尤其在划中心有孔的大直径工件的同心圆时,效果更佳。不但可以省去填圆心、找中心点等工序,而且能提高划线质量。现介绍几种主要用途和使用方法: 一、划同心圆:先将轴承3贴紧工件己加工面(内外圆均可),尺体D面贴紧工件端面。把划针2落至所需位置,拧紧螺钉1,把滑尺6调至大概
We made a custom-made ruler with both centerline performance and a scribing tool for compasses and height vernier caliper parts. After more than a year of use, the effect is better. Especially when centering on a concentric circle of large-diameter workpieces with holes, the effect is better. Not only can save the center of the circle, find the center of the process, but also can improve the quality of marking. Now introduce several main uses and methods of use: First, draw the concentric circles: first bearing 3 close to the workpiece has been machined surface (both inside and outside the circle can be), the scale body D face close to the workpiece surface. Drop the needle 2 to the desired position, tighten the screw 1 and adjust the slide 6 to approx
