A supercharger turbine assembly heavy removal tooling

Abstract

The invention provides a supercharger turbine assembly de-weighting tool. A support plate (2) is installed on a tool rack (1) of the de-weighting tool; a limiting plate (3) is arranged on the support plate (2); a turbine main shaft clamping groove is formed in the side surface of the limiting plate (3); an air cylinder A push block (5) is installed on an air cylinder A (4); the air cylinder A (4) can be connected with a control component (6) which is capable of controlling the air cylinder A push block (5) to stretch; an electric grinding head (7) is arranged on the tool rack (1); a grinding wheel (8) is arranged on the electric grinding head (7); and the electric grinding head (7) is connected with the control component (6) which is capable of controlling the grinding wheel (8) of the electric grinding head (7). The supercharger turbine assembly de-weighting tool is simple in structure, and is capable of conveniently and rapidly completing the turbine small head de-weighting process and the turbine back de-weighting process of supercharger turbine assemblies, effectively reducing the vibration and noise generated by superchargers and prolonging the service life of the superchargers.

Description

technical field [0001] The invention belongs to the technical field of supercharger production and processing auxiliary equipment, and more specifically relates to a supercharger turbine assembly deduplication tooling. Background technique [0002] Due to reasons such as structural design, uneven material, and manufacturing and installation errors, the turbine spindle of the turbocharger turbine assembly deviates from its rotation axis to a certain extent. When the supercharger is working, the rotor is unbalanced. The compressor generates vibration and noise, which may cause friction between the impeller and casing inside the turbine assembly, wear of accelerated bearings and sealing parts, etc., which reduces the mechanical efficiency of the supercharger, and even causes rotor damage in severe cases. damage. In order to improve the working condition of the supercharger, the supercharger turbine assembly must be strictly balanced and deweighted during manufacture and instal...

AI Technical Summary

Problems solved by technology

The automatic de-weighting machine with automatic de-weighting method is expensive, and the adaptability of the fixture is small, which is not suitable for the de-weighting of multiple varieties and models of impellers. Therefore, many enterprises choose manual de-weighting.

However, due to the lack of necessary fixtures or unreasonable design of fixtures, there are some disadvantages in this de-weighting method, such as the unsightly de-weighting position of the turbine assembly, difficult control of the weight-removing size and de-weighting depth of the turbine assembly, manual clamping fraught with certain dangers, etc.

At present, the turbine blank is produced by casting, and the unbalance of the turbine in this process is out of tolerance. Before the supercharger is assembled, it is necessary to carry out the dynamic balance and weight removal of the single body
