摘　　要：为了降低力矩扳手体积对传感器大小的限制,在不降低扳手质量的前提下,设计一款用薄膜应变片代替扭矩传感器测量扭矩的力矩扳手。通过设计壳体材料及外形,满足应变片检测的技术要求,通过制定扳手外壳的铣削工艺规范,获得满足设计要求的力矩扳手壳体,对测量形变进行标定。In order to reduce the restriction of torque wrench size to the size of sensors without sacrificing the quality of torque wrenches,a new type of torque wrenches uses a thin-film strain gauge instead of a torque sensor to measure torque.The design of the shell's material and shape meets the technical requirements for strain gauge testing.The torque wrench shell that meets the design requirements is made strictly in accordance with the special milling processing specification,and the measured deformation is calibrated.
