Abstract

The invention discloses an automatic press-fitting machine for hub assemblies of drive axles, and belongs to the technical field of axle assembly. The automatic press-fitting machine for the hub assemblies of the drive axles overcomes the defects of high labor intensity, low efficiency and difficulty in guaranteeing the quality of traditional hub assembly press-fitting in the prior art. A main structure of the automatic press-fitting machine includes a machine tool body assembly, a positioning assembly and a positioning press-fitting assembly, and the positioning assembly and the positioning press-fitting assembly are separately installed on the machine tool body assembly. The automatic press-fitting machine is mainly used for the automatic press-fitting of the hub assemblies of axle assembly lines of construction machinery loader drive axles and heavy truck drive axles.

Description

Technical field: [0001] The invention belongs to the technical field of vehicle axle assembly, and in particular relates to an automatic press-fitting machine for a drive axle wheel hub assembly. Background technique: [0002] During the assembly process of the drive axle, the press-fitting process of the wheel hub assembly is to press-fit the wheel hub bearings to the axle support shaft. The reliable and fast press-fitting of the wheel hub assembly is of great significance to the assembly quality and efficiency of the drive axle. The traditional wheel hub assembly press-fitting method, one is manual knocking and pressing, which is labor-intensive, inefficient, and difficult to guarantee quality; the other is to use a hydraulic press to press-fit wheel bearings on one or both sides. It is still necessary to manually operate the press, which is not efficient, and it is difficult to ensure the precise positioning of the wheel hub and the axle housing, and the problem of damage...
