Abstract

The invention relates to a grinding process applied to a high-precision easy-to-assemble hub unit, and belongs to the technical field of hub unit machining. The grinding process comprises the following steps that a spline hole of a hub flange is machined and formed to serve as an axis reference, an inner ring clamping groove of the hub flange is machined, and an outer ring flange and a flange holeof the outer ring flange are roughly turned according to the axis reference; then the nesting process of an inner ring and the hub flange is completed through an oil press; a motor sliding air cylinder seat at the front end of a machine base drives an inner locking notch and channel grinding assembly to be inserted into the outer ring flange, and a motor sliding air cylinder seat at the side endof the machine base drives an outer locking notch and channel grinding wheel to be close to the outer side end of the hub flange with the inner ring; and the outer locking notch and channel grinding wheel conducts displacement grinding from the outer wall of the hub flange with the inner ring, and the inner locking notch and channel grinding assembly grinds a locking notch and a channel in the outer ring flange. The grinding process has the advantages of good operation stability, high precision and long service life, and the problem that the machining coaxiality of locking notches and channelsof an outer ring flange, an inner ring and a hub flange is poor is solved.

Description

Technical field [0001] The invention relates to the technical field of hub unit processing, in particular to a wheel hub unit grinding process applied to high precision and easy assembly. Background technique [0002] Automobile hub unit bearings generally use double-row ball bearings. Bearing installation, oiling, sealing, and clearance adjustment are all carried out on the automobile production line. When the car is maintained in a repair shop, the bearings also need to be cleaned, oiled and adjusted. However, the current outer ring flange, inner ring and hub flange's locks and grooves are processed separately, and there are processing errors. [0003] At present, the automobile wheel hub unit of the prior art has a relatively complicated structure, low strength, troublesome installation, and poor use effect, resulting in an increase in maintenance costs. In order to improve the service life and strength of the product, the product adopts special production materials and lean p...
