An automatic assembly machine and assembly method for an automobile hub bearing outer ring assembly

Abstract

The invention provides an automatic assembly machine for an automobile hub bearing outer ring assembly and an assembly method thereof, including a feeding mechanism, an XZ-axis Cartesian coordinate robot, an auxiliary assembly platform, a workbench and a frame. The execution end of the XZ-axis Cartesian coordinate robot is a flat Open the mechanical jaws, which clamp the outer ring of the hub bearing, and assemble with the two cages with balls placed on the auxiliary assembly table. The invention can obliquely assemble the cage with the balls installed, squeeze into the outer ring of the automobile hub bearing under the minimum deformation amount, and complete the assembly.

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.
