Device for automatically and synchronously assembling magnetic shoes and U-shaped spring of direct-current motor

Abstract

The invention provides a device for automatically and synchronously assembling magnetic shoes and a U-shaped spring of a direct-current motor. The device comprises a positioning device, a U-shaped spring closing device, a magnetic shoe vacuum suction device and a motor shell placing device, wherein the positioning device is provided with a vertical straight line main guide rail and a longitudinal supporting straight bearing; with the adoption of the U-shaped spring closing device, the U-shaped spring is forced to be closed through a guide groove of a U-shaped spring closing guide block, so that the closing state of the U-shaped spring is kept by a U-shaped spring closing rod driven by a closing air cylinder before mounting the U-shaped spring in the motor shell; the magnetic shoe vacuum suction device fixes magnetic shoes with an accurate standard at accurate positions; and the motor shell placing device is used for positioning and supporting the motor shell. With the adoption of the device provided by the invention, the U-shaped spring and the magnetic shoes can be automatically and synchronously assembled; furthermore, the U-shaped spring cannot scrap the lateral faces of the magnetic shoes in an assembling process; and a position distance of mounting the U-shaped spring between the two magnetic shoes is precisely controlled by using serve drive accurate positioning properties. Therefore, the operation labor intensity is effectively reduced, and the assembly operation efficiency and the assembly quality of the magnetic shoes and the U-shaped spring are improved.
