扭簧式测微计中的圆簧片(膜片形平弹簧)和方簧片(上平弹簧)是控制仪表测力,起着力的传动和缓冲的重要作用。目前使用的国产扭簧式测微计和瑞典 CEJ、德国蔡司厂出的仪表,由于零件缺乏,给修理工作带来一定的困难。我厂计量室人员在兄弟单位的指导下,用铜皮照相腐蚀法自制了圆簧片和方簧片。满足了修理的需要,提高了工作效率与零件的精度,经使用证明:效果尚好。其制造工艺、兹简述如下,以供参考。1.照相制底板把圆簧片的尺寸放大2倍,在铜版纸上制图,然后反拍成尺寸为1:1的底版。
Torsion spring type micrometer in the spring reed (diaphragm-shaped spring) and spring reed (spring) is to control the instrument measuring the force, the transmission and buffer plays an important role. Currently used domestic torsion spring micrometer and Sweden CEJ, Germany Zeiss plant out of the instrument, due to lack of parts, to the repair work to bring some difficulties. I plant measurement room staff under the guidance of the brothers unit, with copper-coated corrosion self-made round reed and reed. To meet the needs of repair, improve work efficiency and accuracy of parts, the use of proof: the effect is still good. The manufacturing process, it is briefly described below, for reference. 1. The photographic base plate magnifies the size of the round reed by a factor of 2, making a chart on coated paper and backfitting into a 1: 1 sized base plate.
