The utility model relates to the technical field of hinge
assembly, and discloses a straight arm base module, which is characterized in that a base vibration disc module and a straight arm vibration disc module are arranged on a vibration disc large plate of the hinge arm base module; the device comprises a base index plate module, a hinge arm
machining index plate module, a feeding
station base pushing module, a base feeding module, a
clockwise vibration plate, an eccentric nail feeding module, an overturning carrying discharging module, a straight arm feeding module, a
rotating disc transfer module, an adjusting screw locking module and an adjusting screw counter locking module. The spiral riveting module and the discharging
station base pushing module are installed on the top of a large plate of the hinged arm base module in a centralized mode, the modularized straight arm base assembling mechanism is formed, through modularized design and integration of multiple procedures, the operation process is simplified, the operation complexity and time waste are reduced, and the production efficiency is improved. By reducing manual operation and avoiding repeated transfer and respective
assembly, the number of needed equipment and storage space are reduced, and the production efficiency is improved and the operation process is simplified.
