Automatic assembling machine for automobile hub bearing outer ring assembly and assembling method thereof

Abstract

The invention provides an automatic assembling machine for an automobile hub bearing outer ring assembly and an assembling method thereof. The automatic assembling machine comprises a feeding mechanism, an XZ-axis rectangular coordinate robot, an auxiliary assembling table, a workbench and a rack, wherein the executing end of the XZ-axis rectangular coordinate robot is a flat-opening mechanical clamping jaw, and the clamping jaw clamps a hub bearing outer ring and is assembled with two retainers which are placed on the auxiliary assembling table and provided with balls. According to the automatic assembling machine for the automobile hub bearing outer ring assembly and the assembling method thereof, the retainers provided with the balls can be obliquely assembled and squeezed into the automobile hub bearing outer ring under the minimum deformation amount, and assembling is completed.

Description

technical field [0001] The invention relates to the field of automatic assembly, in particular to an automatic assembly machine for an outer ring assembly of an automobile hub bearing and an assembly method thereof. Background technique [0002] The third generation of automotive wheel bearings integrates multifunctional components into the bearing, resulting in a complex structure. Wheel bearings are the core components of automobiles, with high demand and high technical requirements. The realization of automatic assembly is conducive to improving the production efficiency of hub bearings, and can improve the assembly accuracy and prolong the service life. [0003] When assembling the outer ring of the third-generation automobile wheel bearing with the cage with balls installed, in order to facilitate the fixing of the cage with balls installed on the outer ring of the automobile wheel hub bearing, a boss is designed in the inner diameter, which can be fastened and install...

[0002] The third generation of automotive wheel bearings integrates multifunctional components into the bearing, resulting in a complex structure

[0003] When assembling the outer ring of the third-generation automobile wheel bearing with the cage with balls installed, in order to facilitate fixing the cage with balls installed, a boss is designed in the inner diameter of the outer ring of the automobile wheel bearing, which can be fastened and installed. The cage of the ball, but because the minimum diameter of the boss is smaller than the maximum outer diameter of the cage with the ball installed, it brings difficulties to automatic assembly

[0005] (1) The assembly tasks are all realized by the cylinder, and the structure is not flexible. Only one kind of hub bearing can be assembled. If a different type of hub bearing is replaced, the structure needs to be greatly changed;

[0006] (2) The cage with the ball installed needs to be squeezed into the outer ring, and the assembly method of this equipment may damage the cage

[0007] At this stage, the assembly of the third-generation automobile wheel bearing outer ring and the cage with the balls installed is mainly done manually. Manual operation will not only pollute the parts, but also has high labor intensity, low assembly efficiency, and unstable assembly quality.
