Valve rocker arm assembly welding tool of turbine shell

Abstract

The invention relates to a valve rocker arm assembly welding tool of a turbine shell. The welding tool is characterized by comprising a substrate, wherein a positioning support plate is connected withthe substrate, a positioning disc is fixedly connected with the positioning support plate, one side of the positioning disc is provided with a linear guide rail, a rocker arm positioning plate is connected with the linear guide rail, a positioning groove for positioning the rocker arm assembly is arranged in the front end of the rocker arm positioning plate, and a connecting block is arranged onthe other side of the positioning plate, a quick clamp and an angular positioning pin are fixedly connected with the connecting block; two positioning pins are arranged on the positioning plate, a topblock is obliquely arranged and is fixedly connected with the positioning plate, and an ejector rod hole is arranged in the front part of the top block, an ejector rod is connected in the ejector rodhole in a sliding mode, and during welding, the positioning plate is positioned by two positioning pins and covers an air outlet of the turbine shell, the ejector rod abuts against the lower portionof a valve transmission shaft assembly, and the positioning plate is tightly clamped by the clamp head of the quick clamp. The device has advantages of being simple and compact in structure, low in manufacturing cost, convenient and rapid in operation, ensured in repeated positioning precision, the working efficiency is improved, the labor intensity of operators is relieved, and the processing cost is reduced.

Description

technical field [0001] The invention relates to a process equipment, in particular to a welding tool for a valve rocker arm assembly of a turbine shell. Background technique [0002] Turbine casing is the main part of turbocharger. As turbocharging technology is more and more widely used in the field of automobile engines, the production volume of turbine casing is also increasing. After the machining of the turbine casing is completed, the valve transmission shaft assembly 2' and the rocker arm assembly 3' need to be assembled to the turbine casing 1' by welding, as Figure 4 As shown, at present, in this process, the valve transmission shaft assembly 2' is inserted into the shaft sleeve hole through the air outlet of the turbine shell 1', and the positioning plate is positioned by the bolt hole of the air outlet flange of the turbine shell 1' and covered on the turbine shell 1'. On the air outlet of the shell 1', screw the screw on the positioning plate into and abut again...
