为了控制电机安装尺寸 A/2,我厂自1975年以来,自制了两种 A/2测量器具~#1和~#2。供首件检验和抽检中应用。它比平板顶测法效率高,而且比较安全。能达到检测要求。~#1测量器具,适用于内外止口的机座测量 A/2。测量时,先将滑体6,滑到所测机座中心高的名义尺寸后,再将尺体5直接放在机座止口平面与三节条铁2上。(用于~#1)机座以上的大止口,见图1)将平尺3靠在机座底脚平面并使尺体垂直于平尺后,用压铁4压住尺体,再撤换掉平尺。用卡尺测量止口与滑体6平面最大距离。因为滑体6长140~(+0.02)和尺体弯板的140~(+0.02)等距并
In order to control the motor installation size A / 2, our factory made two A / 2 measuring devices ~ # 1 and ~ # 2 since 1975. For the first piece of inspection and sampling applications. It is more efficient and safer than flat-top methods. Can meet the testing requirements. ~ # 1 measuring device, suitable for both the outer and the base measurement A / 2. Measurement, the first slide 6, slide to the measured center of the nominal height of the seat size, and then the body 5 directly on the seat plane and three flat iron 2. (For ~ # 1) above the base of the large stop, see Figure 1) The flat ruler 3 leaning against the base plane feet and make the ruler perpendicular to the flat ruler, with the pressure of 4 to suppress the ruler, and then Remove the flat feet. Use calipers to measure the maximum distance between the stop and the slide 6 plane. Because of the slide body 6 long 140 ~ (+0.02) and the ruler plate 140 ~ (+0.02) equidistant and
