A method of processing a compressor impeller

Abstract

The invention relates to the field of compressor impeller manufacturing, in particular to a machining method of a compressor impeller. The machining method of the compressor impeller comprises the following steps that 1, the compressor impeller is arranged on a machine tool provided with a first clamp tooling, and the front shaft end of the compressor impeller stretches into a clamping hole of thefirst clamp tooling; 2, an expansion block of the first clamp tooling shrinks to clamp the front shaft end of the compressor impeller, and a root portion of the wheel face of the compressor impellerabuts against the end face of a free end of a limiting cover; 3, wheel back of the compressor impeller and an outer circle of the compressor impeller are machined, and a tool is changed to machine theinner hole of the compressor impeller; 4, a workpiece in step 3 is unloaded and arranged on the machine tool provided with a second clamp tooling, and the wheel back of the compressor impeller abutsagainst any seam allowance face located at the circular edge of a clamping hole of the second clamp tooling; 5, a clamping block of the second clamp tooling shrinks to fix the workpiece, and a front end roof pillar of a connecting shaft of the second clamp tooling abuts against the wheel back of the compressor impeller; and 6, a R end face of the compressor impeller and the end face of the front shaft end are machined. The machining method of the compressor impeller can effectively guarantee the accuracy of subsequent balance.

Description

technical field [0001] The invention relates to the production field of a compressor impeller supercharger, in particular to a processing method of an air compressor impeller. Background technique [0002] In the prior art, when processing the compressor impeller, such as Figure 6~7 As shown, the outer circle of the compressor impeller is first held by the three claws, and the front end of the three claws is against the outer limit of the wheel surface, then the inner hole is processed on the back of the wheel, and then the bed is inserted into the compressor impeller using the expansion shaft The compressor impeller is fixed in the inner hole, and the R end face and the shaft end face are fixed. In this way, the three-claw front end is used to resist the outer edge of the wheel face, and the outer circle of the compressor impeller face is larger, so the machining accuracy and balance accuracy There is still room for improvement.
