为了比较精确地测量一些重要螺栓的预紧程度和检测定扭扳手及安全攻丝夹头的预定扭矩,我们设计制造了一种新颖的测扭矩扳手。用带阻尼的百分表记录扭矩值。经实际标定1kg·m扭矩,表针增值为0.065～0.07毫米。扭矩和表值基本上呈线性关系。扳轴两端都是13×13方头,分别用来检测拧紧扭矩和松开扭矩。可测试的最大扭矩为20kg·m。如果更换或改变应力环的尺寸,就可扩大或缩小扳手的量程。

In order to more accurately measure the preload of some important bolts and to detect the predetermined torque of the torque wrench and the safety tapping chucks, we designed and manufactured a novel torque wrench. Torque values ​​recorded with damping dial indicator. The actual calibration 1kg · m torque, needle increment value of 0.065 ~ 0.07 mm. Torque and table values ​​are basically linear. Both ends of the mandrel are 13 × 13 square head, were used to detect tightening torque and release torque. The maximum torque that can be tested is 20kg · m. If you change or change the size of the stress ring, you can expand or reduce the span of the wrench.
