Bolt friction coefficient measuring device

The utility model provides a bolt friction coefficient measuring device, which comprises a mounting mechanism, a bolt mounting module, a nut mounting module, an axial force detection module and a torque detection module, and is characterized in that the bolt mounting module and the nut mounting module are detachably connected onto the mounting mechanism; the nut installation module comprises a first adjustable pressing assembly for installing a nut. The bolt installation module comprises a second adjustable pressing assembly for installing a tested bolt. The first adjustable pressing assembly and the second adjustable pressing assembly are oppositely arranged, so that the tested bolt is matched with the tested nut; the axial force detection module and the torque detection module are both connected with a detected bolt. The bolt friction coefficient measuring device provided by the utility model can quickly measure the connection of bolts with different specifications. 本实用新型提供一种螺栓摩擦系数测量装置，包括安装机构、螺栓安装模块、螺母安装模块、
