A turbine shell rocker arm welding tool

Abstract

The invention provides a turbine shell rocker arm welding tool, which includes a bottom plate, a turbine shell fixing mechanism, a bypass valve limit mechanism and a rocker positioning plate; the turbine shell fixing mechanism includes a support vertical plate fixed on the bottom plate, a positioning seat and The limit plate; the limit mechanism of the bypass valve includes a limit support and a limit push rod fixed on the bottom plate, and the end of the limit push rod is provided with a limit pressure head; On the positioning seat, the limit plate cooperates with the outer wall of the turbine shell flow channel to limit the rotation of the turbine shell, push the limit push rod to the working position, make the limit pressure head press the bypass valve, and one end of the rocker arm positioning plate is fixed on the support The top of the vertical plate and the other end are provided with a positioning hole, so that the positioning hole is sleeved on the handle of the rocker arm. The invention fixes the position of the turbine casing through the turbine casing fixing mechanism, restricts the swing of the bypass valve through the bypass valve limiting mechanism, realizes precise positioning, and ensures welding accuracy. At the same time, the installation process of the tooling is simple and the welding efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of turbine shell rocker arm welding, and in particular relates to a turbine shell rocker arm welding tool. Background technique [0002] Turbine shell is the main part of turbocharger. The turbocharger with bypass valve can obviously improve the low-speed performance of the car, increase the low-speed torque, reduce the fuel consumption and pollution at low speed, and improve the performance of the engine at high speed. Indicators and use reliability. The turbocharger with a bypass valve needs to be equipped with a rocker arm operation room to control the bypass valve. When welding the rocker arm of the turbine shell, there are not only requirements for the clearance between the rocker arm and the bushing, but also extremely high requirements for the angle of the rocker arm. [0003] The existing welding tooling for the valve rocker arm assembly of the turbine shell, the process of fixing the turbine shell...

AI Technical Summary

Problems solved by technology

[0003] The existing welding tooling for the valve rocker arm assembly of the turbine shell, the process of fixing the turbine shell and the rocker arm assembly is cumbersome, a lot of time will be wasted in actual operation, and the welding efficiency is low; Provide support, but cannot effectively control the swing of the valve transmission assembly in the left and right directions, resulting in low welding accuracy
