Processing method of power axle

Abstract

The invention provides a processing method of a power axle. The power axle comprises a U-shaped base body, the U-shaped base body comprises an inward concave inner baffle and a side face, and the inner baffle comprises an upper mounting surface and a bottom surface. Sinking tables are arranged at the two ends of the U-shaped base body. Middle bosses are arranged on the opposite surfaces of the inner baffle. A center shaft is arranged on the side, far away from the inner baffle, of each sinking table. The center shafts are located on the same center line. A first through hole is formed in the center of each center shaft. A mounting hole is formed in the upper end face of each sinking table. Threads are arranged at two ends of each center shaft. The processing method comprises the following steps of casting, scribing, rough milling of the bottom surface, rough milling of the top surface, end surface milling and center hole drilling, rough turning, primary finishing, primary flaw detection, hardening and tempering, tie bar gas cutting, secondary finishing, primary detection, semi-finish milling of the bottom surface, semi-finish milling of a mounting surface, semi-finish milling of the two ends, tertiary finishing, magnetic powder flaw detection, finish milling of the bottom surface, finish milling of the mounting surface, finish milling of the two ends, positioning hole drilling, semi-finish turning, finish boring, key groove milling, finish turning and rolling, counterweight dismounting, bench worker tapping, quartus finishing, magnetic powder flaw detection and cleaning.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method of a power shaft bridge. Background technique [0002] With the development of society, the concept of urban rail transit development such as energy saving and environmental protection has been continuously improved, and energy storage trams have emerged. The so-called energy storage trams refer to the use of energy storage components to store electric energy as power for traction. Vehicles The receiver installed on the roof is in contact with the rails to obtain current, which has the advantages of being green and environmentally friendly. It is precisely because of the above characteristics that this model has been more and more popularized and used. [0003] And the tramway replaces the traditional axle with the axle-bridge device, and the axle-bridge device will not rotate with the wheels, the axle-bridge is divided into power axle-bridge and...

AI Technical Summary

Problems solved by technology

[0003] And the tramway replaces the traditional axle with the axle-bridge device, and the axle-bridge device will not rotate with the wheels, the axle-bridge is divided into power axle-bridge and non-power axle-bridge, the production cost of the existing power axle-bridge is high, and the power axle The bridge bears high strength, so the precision requirement is very high, and the existing processing method has a high scrap rate
