摘要： 针对现有扭矩扳子检定仪的使用现状，结合当前先进的机械制造和测控技术，设计一种测量范围大、具有三维调节加载机构的扭矩扳子检定仪，着重研究解决了三维调节机构中的空间结构和易用性的平衡，并通过多向支承轴承机构设计实现了圆周加载的要求。使用先进的计算机测控技术和软件设计，提升装置智能化水平，提高工作效率。

Abstract: Aimed at the current situation of application of torque wrench calibrator, combining advanced machine manufacturing and observation and control technology at present, in this study we designed a kind of torque wrench calibrator with wide measuring range and three-dimensional regulating mechanism. The calibrator emphatically realized the balance between space structure and usability of 3D regulating mechanism; in addition, met the requirement of circular loading by devising bearing structure with multi-directional fulcrum bearing. Besides, equipped with advanced technique of computer measurement and control and software design, the equipment can also help generate new level of intelligence, meanwhile improve work efficiency.
