The invention provides a bidirectional dovetail self-centering composite differential screw locking mechanism which is provided with a vehicle-mounted support and a battery box, battery box beams are arranged in the middles of the two sides of the battery box, and the vehicle-mounted support and the battery box are fixedly connected through the differential screw locking mechanism. The differential spiral locking mechanism comprises a vehicle-mounted support fixing dovetail sliding table assembly and a battery box beam fixing dovetail sliding table assembly. The vehicle-mounted support fixing dovetail sliding table assembly comprises a Y-direction dovetail sliding table, a Y-direction dovetail sliding plate and a Z-direction self-centering conical nut hanging rod. The battery box girder fixing dovetail sliding table assembly comprises an X-direction dovetail sliding table, an X-direction dovetail sliding plate and a step locking screw. The device is simple in structure and convenient to operate, a gap between a battery box beam and a vehicle-mounted bracket is eliminated through three-axis self-centering positioning adjustment and by adopting a two-stage composite differential screw transmission structure, a battery box is quickly and firmly fixed on the vehicle-mounted bracket, and the device can be widely applied to the technical field of new energy battery replacement.

    本发明提供一种双向燕尾自对中复合式差动螺旋锁紧机构,其设有车载支架和电池箱,电池箱的两侧中部设有电池箱梁,车载支架和电池箱通过差动螺旋锁紧机构固定连接,差动螺旋锁紧机构包括车载支架固定燕尾滑台组件和电池箱梁固定燕尾滑台组件。车载支架固定燕尾滑台组件包括Y向燕尾滑台、Y向燕尾滑板和Z向自对中锥形螺母吊杆,电池箱梁固定燕尾滑台组件包括X向燕尾滑台、X向燕尾滑板和阶梯锁紧螺杆。本发明结构简单,操作方便,通过三轴自对中定位调节,同时采用两级复合式差动螺旋传动结构,消除电池箱梁和车载支架之间的间隙,将电池箱快速且牢固的固定在车载支架上,可广泛应用于新能源换电技术领域。
