Abstract

The invention discloses an engine exhaust vortex back elbow assembling method and a tool thereof. The tool comprises a bolt, a fastening bolt a, a bracket, a limiting plate, a positioning pin, a fastening bolt b and a clamp spring. The engine exhaust vortex back elbow assembling method comprises the following steps: fixing the bracket of the engine exhaust turbine back elbow assembling tool on a screw hole on the side surface of an engine body through the fastening bolt a; inserting the bolt into the bolt head of an engine oil cooler on the side surface of an engine, and fastening the fastening bolt a; placing an exhaust vortex back elbow of the engine on a limiting plate above the bracket of the engine exhaust vortex back elbow assembling tool, and controlling the bottom surface of the exhaust vortex back elbow to be attached to the surface of the limiting plate; and then tightening a hoop connected with the exhaust vortex back elbow and an engine supercharger. Through the assembly design, the installation angle of the exhaust vortex back elbow needing controlling can be guaranteed, meanwhile, the operation is convenient, and the working efficiency is obviously improved.

Description

technical field [0001] The invention relates to engine assembly and manufacturing technology, in particular to an assembly method and tooling for an engine exhaust vortex rear elbow. Background technique [0002] During the assembly process of the engine, it is necessary to control the installation angle of the exhaust vortex rear elbow. The connection between the exhaust vortex back elbow and the engine supercharger is in the form of a hoop, and the exhaust vortex back elbow can rotate at a certain angle around the center of the turbocharger exhaust port. If the installation angle of the exhaust vortex rear elbow is wrong, it will cause interference between the exhaust pipe supplied to the automobile factory and the engine or the whole vehicle. At present, after the exhaust vortex elbow is assembled, tools such as angle gauges are used to adjust it, which is inconvenient to operate, and the long working time seriously affects the production and delivery output of the engin...
