在仪器仪表的修理过程中,特别是进行光电比色,分光光度计的检流计吊丝焊接时,需要将吊丝的支架固定好,再进行吊丝的焊接。以往固定支架的方法也多种多样,往往需要他人的帮助才能完成,感到不够方便。本人制作了一只简易万能夹座(如图示),通过二年多的检修实践,认为还是比较理想的。使用时当央头钳好工件后,如需工件成水平、垂直、高低、倾斜等位置,只要分别松开上下紧固螺丝,适当转动铁棒(或铜棒)或转动固定夹,即可达到目的。这种夹座制作很简单,材料也是因陋就简。如夹座里的夹头和固定夹均是外购件,底座是一块用过的布氏硬度块。只要把夹头固定 In the instrument repair process, especially for photoelectric colorimetric, spectrophotometer galvanometer hanging wire welding, the need to be fixed wire hanging bracket, then the hanging wire welding. In the past, the methods of fixing the brackets also varied, often requiring the help of others to complete and felt inconvenient. I made a simple universal clip (pictured), through more than two years of maintenance practice, that is still quite ideal. When the use of the central head after the first clamp the workpiece, for the workpiece into a horizontal, vertical, height, tilt and other positions, as long as the upper and lower fastening screws were loosen, appropriate rotation of the iron rod (or copper rod) or turn the fixed clip, you can reach purpose. This clip seat making is very simple, the material is simple. Such as the folder in the chuck and clip are purchased parts, the base is a used Brinell hardness block. Just fix the collet
