Automatic press-fitting device for gearbox output shaft

Abstract

The invention discloses an automatic press-fitting device for a gearbox output shaft, and relates to the field of automobile parts. The automatic press-fitting device comprises a fixed mounting base,an output shaft conveying device, a press-fitting device, a pressure head switching device, a bearing inner ring press-fitting pressure head, a bearing outer ring press-fitting pressure head and a mounting fixing plate, wherein the fixed mounting base is used for mounting and fixing equipment on the ground, and is also a fixed carrier of other devices; the output shaft is manually placed on the output shaft conveying device; the output shaft conveying device is used for conveying the output shaft to a press-fitting position; the press-fitting device is used for pushing the bearing inner ring press-fitting pressure head to perform bearing inner ring press-fitting firstly; after the bearing inner ring press-fitting is completed, the pressure head switching device is used for switching the bearing outer ring press-fitting pressure head to a specified position; the press-fitting device is used for pushing the bearing outer ring press-fitting pressure head again; after the press-fitting iscompleted, the output shaft conveying device is used for conveying the output shaft to an original position; and a workpiece is manually taken down. The automatic press-fitting device is high in automation rate, convenient to use, and stable in bearing press-fitting process.

Description

technical field [0001] The invention relates to the field of assembly of auto parts, in particular to an automatic press-fitting device for an output shaft of a gearbox. Background technique [0002] The output shaft of the gearbox is directly meshed with the main reduction gear of the differential. The large transmission torque requires a high press-fit process for the output shaft bearings, and it is difficult to control the press-fit force and stroke. In order to solve this problem, the application number CN03234327.2 discloses an output shaft press-fitting device, which has a low degree of automation, is inconvenient to operate, and has the risk of wearing the workpiece when positioning the workpiece, so it cannot be widely used in the production process. Contents of the invention [0003] In view of the above technical problems, the present invention provides an automatic press-fitting device for the output shaft of a gearbox, which includes a fixed mounting base, an ...
