精密扭力天平结构简单,灵敏度高,使用方便。特点是零部件纤细,机械强度低,容易变形、损坏。检修时,通用工具往往是“英雄无用武之地”。因此,研制一些专用的小工具很有必要。现在,就我们自己在实际工作中使用的几个自制的专用小工具,简单介绍如下: 一、桩头矫正别棍有时扭力天平的示值误差超出允许范围,查其原因,通常发现游丝(平卷簧)形状不正常:整盘游丝不在同一平面内,或者游丝平面不铅垂。原因是横梁桩头变形(倾斜、弯曲等)而牵动游丝所致。修理时,使用一个专门的矫正工具——矫正别棍,对变形的桩头进行调整比较方便。图1所示的矫正别棍是利用废旧解锥(罗
Precision torque balance simple structure, high sensitivity, easy to use. Features are slender parts, low mechanical strength, easy deformation, damage. Overhaul, the common tool is often “hero useless.” Therefore, the development of some special gadgets is necessary. Now, on our own work in the use of several self-made special gadgets, a brief introduction is as follows: First, the pile correction stick sometimes torsion balance indication error exceeds the allowable range, check the reason, usually found that the balance spring Coil spring) shape is not normal: the whole plate hairspring is not in the same plane, or hairspring plane is not vertical. The reason is the deformation of the beam head (tilt, bending, etc.) and affect the hairspring caused. Repair, the use of a special correction tools - Correction stick, the deformation of the pile head to adjust more convenient. Correction stick shown in Figure 1 is the use of waste solution cone (Luo
