Problems solved by technology

[0002] The existing processing technology is to process the back of the impeller by positioning the rough surface of the small diameter of the impeller. Due to the misalignment between the impeller blade and the hub when casting, and the error of clamping, the thickness of the bottom surface of the processed impeller hub and the back of the impeller is There is a large size drop in the gap, which leads to a large amount of unbalance of the finished impeller, which seriously affects the quality level of the impeller

Embodiment Construction

[0008] The machining process of positioning the bottom surface of the hub of the turbocharger impeller includes the following process:

[0009] When the impeller is clamped, the hub nut end is clamped by the hydraulic chuck, and then tightened into the spindle box of the lathe. A special fixture is installed on the spindle, and three point-shaped supporting surfaces that are on the same plane and perpendicular to the spindle are supported. At A on the bottom surface of the impeller hub, the impeller hub is coaxial with the turning center of the lathe and the bottom surface is perpendicular to the turning center, which can ensure that the drop between the processed impeller hub bottom surface and the wheel back is within a small range.

Abstract

The invention relates to a process for machining a positioning lathe of the bottom face of an impeller hub of a supercharger. The process is characterized by comprising the following process steps: clamping a nut end of a hub by a hydraulic chunk in an impeller clamping process; tensioning the nut end of the hub inwards a lathe spindle box; mounting a special clamp on a spindle; ejecting against the A position of the bottom face of the impeller hub by three point-shaped bearing faces which are located on the same plane and are vertical with the spindle, so that the impeller hub is coaxial to the rotation center of the lathe and the bottom face of the impeller hub is vertical with the rotation center, and the drop of the processed bottom face of the impeller hub and the back of the impeller can be controlled within a very small range. The process provided by the invention has the advantages of simple structure, low requirements on skills of an operator, high efficiency and good quality of the impeller, and is particularly applicable to mass production.

Description

technical field [0001] The invention relates to a supercharger, in particular to a positioning lathing process for the bottom surface of the impeller hub of the supercharger. Background technique [0002] The existing processing technology is to process the back of the impeller by positioning the rough surface of the small diameter of the impeller. Due to the misalignment between the impeller blade and the hub when casting, and the error of clamping, the thickness of the bottom surface of the processed impeller hub and the back of the impeller is There is a large size drop in the difference, which leads to a large amount of unbalance in the finished impeller, which seriously affects the quality level of the impeller. Contents of the invention [0003] The object of the present invention is considered to overcome the defects and deficiencies in the above-mentioned prior art, and to provide a process for positioning the bottom surface of the turbocharger impeller hub.
