Full-automatic numerical control hub bearing unit assembly finished product composite numerical control lathe

Abstract

The full-automatic numerical control hub bearing unit assembly finished product composite numerical control lathe comprises a machine base, a workbench, a hydraulic station, a lower main shaft unit, an upper main shaft unit, a hydraulic rotary tool turret machining unit and a numerical control system electrical unit, and an air pressure control valve and an electromagnetic valve set are arranged on the lower portion of the machine base. Products turned by the equipment can effectively ensure that the axial run-out and the radial run-out of a hub bearing unit assembly are within a product design parameter range, the percent of pass of hub bearing units is increased, the reliability of product quality is effectively ensured, the labor cost is reduced, the productivity is improved, and the production cost of the hub bearing units is reduced; equipment is automatically controlled by a numerical control system, and the tool is easy to manufacture and convenient to operate; the machining precision is high.

Description

technical field [0001] The invention relates to production equipment for wheel hub bearing units, in particular to a fully automatic numerically controlled wheel hub bearing unit assembly finished compound numerically controlled lathe. Background technique [0002] At present, the hub bearing unit is an important safety component in the car. To ensure that the car runs normally on the road, the two pairs of front and rear wheels need to rotate relatively parallel to work. If one wheel shakes and swings when driving at high speed, it will be difficult for the driver to control the driving direction of the car normally, and the car will not be able to control the normal operation of the car, which will easily cause the brakes of the car to fail, the direction cannot be controlled normally, and even cause traffic accidents; how to ensure the four If the tires can run relatively parallel, it is necessary to ensure that the wheels of the car have no axial and radial swings, and ...

AI Technical Summary

Problems solved by technology

[0003] Due to the long production and processing process of each part of the hub bearing, some assembly errors will also be caused during the assembly process of the hub bearing; after these errors are accumulated, the axial runout and end face runout of the assembled hub bearing unit assembly will be large; it cannot meet the needs of automobiles. Factory installation technical requirements; At present, each hub unit manufacturer treats the products with large axial runout and large radial runout of the hub unit assembly, and conducts manual full inspection before leaving the factory to select out the products with large axial runout and large radial runout , carry out price reduction sales or product scrapping

This causes the production cost of the hub bearing unit to rise sharply, and additional labor costs will be added

In the traditional production process, once the production and assembly of the hub bearing unit assembly is completed, the axial runout and radial runout out-of-tolerance products cannot be repaired by traditional processing methods; it is a pity to deal with such products
