Abstract
The invention relates to a machining method for a hollow shaft. The machining method includes the steps that workblank materials are loaded on a machining center for bright turning and peel removing, and a standard bar is machined; the standard bar is arranged into a milling machine under the oil cooling working condition, and a standard face is milled; under the conditions of oil cooling and inert gas shielding, the bar is vertically placed into the machining center, a datum plane is defined, the center of the bar is hollowed, the outer surface is machined to be in the size with various outer diameter, certain chamfers should be reserved between various outer diameters, and therefore structure stress is prevented; and when the two ends of the bar are sealed, interference fit assemblies should be used, hydraulic assembling is carried out, and precise flaw detection needs to be carried out after assembling is carried out. The condition that damage is not found in the assembling and machining process, and a next working procedure is executed, and consequently, a shaft is likely to be broken is avoided. The machining method has the beneficial effect that the practical effect is good.
Description
Technical field: the invention belongs to Machining Technology field, particularly a kind of processing method of hollow shaft.
Background technology:
At present, existing hollow shaft processing method efficiency is low, and practical function is bad.
Summary of the invention:
In order to solve the deficiencies in the prior art, the invention provides a kind of hollow shaft method.
The present invention includes: blank material is loaded onto the bright peeling of machining center car, be processed into standard bar.Milling machine is put under standard bar being placed in the operating mode of oil cooling; mill out index plane; this bar is vertically put into machining center; define datum level; when oil cooling and inert gas shielding, bar center is emptied, outer surface is processed into the size of various external diameter; note retaining certain chamfering between various external diameter, prevent structural stress.Will note during this bar sealing two ends using Interference Fitted Assemblies, hydraulic pressure assembles, and wants precise examination after assembling.Prevent the assembly machine damage added in process from not having discovery to enter next procedure, cause axle easy fracture.
Advantage of the present invention: good practical effect of the present invention.
