This utility model belongs to the field of
battery pack positioning technology, specifically relating to a quick-change precision positioning device for a PACK
production line tooling trolley. It includes a trolley, a guide
assembly, and a quick-change mechanism. A positioning pin is set at the bottom of the guide
assembly, which inserts into a positioning hole on the trolley. The quick-change mechanism includes a
thumb-shaped clamp and a
cam sleeve. The lower end of the
thumb-shaped clamp is inserted into the
cam sleeve, and quick locking or unlocking is achieved by rotating a knob. The trolley tray has multiple pre-set
cam sleeve mounting positions, each corresponding to a
product model. The guide
assembly integrates a coarse guide, support, and precision positioning mechanism for the PACK placement on the top of the mounting plate, with at least two
thumb-shaped clamps symmetrically arranged at the bottom to ensure balanced locking force. This device, through the pre-positioning cooperation between the positioning pin and the positioning hole and the thumb-shaped clamp's quick-locking structure, avoids the cumbersome operation of traditional bolt disassembly, achieving second-level model
changeover. The multiple mounting positions support rapid model
changeover, improving
production line flexibility and assembly efficiency.
