Abstract

The utility model relates to an automatic pin press-fitting device and system. The automatic pin press-fitting device comprises a workpiece transferring tool, a first pin receiving tool, a second pin receiving tool and a press-fitting tool. The pin press-fitting tool has the advantages that the press-fitting tool adopts a single-shaft manipulator (namely a third vertical movement mechanism) for automatic assembly, so that the perpendicularity and height of pin press-fitting are ensured, and the consistency of product assembly is ensured; the press-fitting work is automatically pressed through a servo press, and pressure and displacement intervals can be set, so that high-precision press-fitting of products is realized, and the press-fitting yield of the products is improved; the installation efficiency is high, it is ensured that the first pin and the second pin are installed in place, and the problem that the product is crushed due to overlarge pressure is avoided; manpower participation is reduced, and the production efficiency is improved.
