Embodiment 1

[0007] The invention includes: loading the rough material into a machining center, turning it, peeling it, and processing it into a standard bar material. Put the standard bar stock into the milling machine under the condition of oil cooling, mill out the standard surface, put the bar stock vertically into the machining center, define the reference plane, and place the bar stock under the condition of oil cooling and inert gas protection The center of the material is hollowed out, and the outer surface is processed into various sizes of outer diameters. Note that certain chamfers are reserved between the various outer diameters to prevent structural stress. When the two ends of the bar are sealed, attention should be paid to the use of interference fit components, hydraulic assembly, and precise flaw detection after assembly. Prevent the damage in the process of assembly machining from entering the next process without being found, causing the shaft to break easily.

Embodiment 2

[0009] The invention includes: loading the blank into a machining center, turning it, peeling it off, and processing it into a standard bar. Put the standard bar stock into the milling machine under the condition of oil cooling, mill out the standard surface, put the bar stock vertically into the machining center, define the reference plane, and place the bar stock under the condition of oil cooling and inert gas protection The center of the material is hollowed out, and the outer surface is processed into various sizes of outer diameters. Note that certain chamfers are reserved between the various outer diameters to prevent structural stress. When the two ends of the bar are sealed, attention should be paid to the use of interference fit components, hydraulic assembly, and precise flaw detection after assembly. Prevent the damage in the process of assembly machining from entering the next process without being found, causing the shaft to break easily.

Embodiment 3

[0011] The invention includes: loading the blank into a machining center, turning it, peeling it off, and processing it into a standard bar. Put the standard bar stock into the milling machine under the condition of oil cooling, mill out the standard surface, put the bar stock vertically into the machining center, define the reference plane, and place the bar stock under the condition of oil cooling and inert gas protection The center of the material is hollowed out, and the outer surface is processed into various sizes of outer diameters. Note that certain chamfers are reserved between the various outer diameters to prevent structural stress. When the two ends of the bar are sealed, attention should be paid to the use of interference fit components, hydraulic assembly, and precise flaw detection after assembly.

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

[0001] Technical field: the present invention belongs to the technical field of mechanical processing, and in particular relates to a processing method of a hollow shaft. Background technique: [0002] At present, the existing hollow shaft processing methods have low efficiency and poor practical effect. Invention content: [0003] In order to solve the deficiencies of the prior art, the present invention provides a hollow shaft method. [0004] The invention includes: loading the blank into a machining center, turning it, peeling it off, and processing it into a standard bar. Put the standard bar stock into the milling machine under the condition of oil cooling, mill out the standard surface, put the bar stock vertically into the machining center, define the reference plane, and place the bar stock under the condition of oil cooling and inert gas protection The center of the material is hollowed out, and the outer surface is processed into various sizes of outer diameters....
