Torsion spring tightening assembly device

Abstract

A torsion spring tightening assembly device is disclosed. After moving downwards, a second piston rod of a taking cylinder immediately moves upwards, a taking slip ring drives magnets to move downwards to be flush with the lower end of the taking column at first, attract a torsion spring, and then drive the torsion spring to move upwards, and a taking device is reset. After the torsion spring is attracted, a taking section at the lower end of the taking column is sleeved with the torsion spring. The assembly device is moved into a limiting post or torsion spring positioning groove of a product to be installed, an output shaft of a rotating cylinder is rotated in the forward direction, and a swing rod drives a pry pin to move towards a limiting rod, so that the torsion spring is tightened. After moving downwards, a first piston rod of an unloading cylinder immediately moves upwards. An unloading slip ring drives an unloading push rod to move downwards, pushing the torsion spring out of the taking column, so that the torsion spring is installed in place. The rotating cylinder drives swing rod to reverse and reset. The assembly device is moved to the location of another torsion spring to be installed, and the above actions are repeated for control. The present disclosure realizes automatic taking and automatic tightening and installation of torsion springs and improves production efficiency; the structure is simple, and stability is high; and detachable connection is adopted, facilitating assembly and maintenance.
