Pressure bearing device

Abstract

The invention provides a pressure bearing device. The pressure bearing device comprises a rear fixing seat, a support seat, a slide pressure block seat and a front fixing seat orderly formed, all parts are connected together through the first guide column, the support seat and the slide pressure block seat can slide along the axial direction of the first guide column; a first pressure bearing device is formed above the rear fixing seat, a support shelf used for supporting and locating the motor rotor workpiece is formed above the support seat, a second pressure bearing device is formed above the slide pressure block seat; the first pressure bearing device comprises a rear bearing tail top and a rear bearing thimble arranged at the axis of the rear bearing tail top and connected with the rear bearing tail top in a slide mode, the rear bearing thimble can extend out or retract in the rear bearing tail top, the rear bearing thimble is used for hanging the bearing and the magnetic ring, the second pressure bearing device comprises a bearing pressure head. The pressure bearing device adopts horizontal type structure, during the pressing process, the force for the magnetic ring and the bearing is even and stable for reducing the damage reject ratio for the bearing, reducing the labour intensity for the operators and reducing the cost.

Description

technical field [0001] The invention relates to the field of motor assembly tools, in particular to a pressure bearing device. Background technique [0002] The existing motor rotor pressure bearing tooling in the industry is divided into upper and lower molds. The lower mold is placed on the base of the beer machine, and a magnetic ring is put on the motor rotor shaft with a circlip. During the press-fitting process, the bearing is put into the lower mold first, then the rotor shaft with magnetic ring is inserted into the bearing, and the bearing is pressed into place by the upper mold. Due to the manual press-in, the bearing and magnetic ring are put in slowly and the force on the bearing is uneven, resulting in a high defect rate of bearing damage after the motor rotor is installed into the motor. Contents of the invention [0003] In view of the status quo of the prior art, the object of the present invention is to provide a pressure bearing device, which adopts a hor...
