Title: DEVICE FOR AUTOMATICALLY PRESS-FITTING SPINDLE
Abstract:
A device for automatically press-fitting spindle comprises a frame (1). The frame (1) is provided with a mold holder (2) for positioning stacked rotor silicon steel sheets. A sleeve (3) for positioning a spindle is provided above the mold holder (2). A driving component (4) is connected to the sleeve (3) to drive the sleeve (3) to slide toward the mold holder (2). The mold holder (2) has a lower stepped hole (21) for accommodating rotor silicon steel sheets having different outer diameters. The sleeve (3) has an upper stepped hole (31) for accommodating spindles having different diameters. A magnet (5) is provided at the bottom of the upper stepped hole (31). The lower stepped hole (21) has a minimum diameter of 3 mm. The upper stepped hole (31) can position spindles having different diameters. The lower stepped hole (21) can position stacked rotor silicon steel sheets having different diameters. When a production specification of a motor changes, there is no need to replace components such as a mold or a fixture, thereby facilitating improving production efficiency.
