Problems solved by technology
[0005]1. Due to the oblique angle of the branch pipe, the accuracy of the tooling is high, and overall processing is required, which increases the production cost;
[0006]2. For the sake of assembly, the tooling materials should not be too bulky, but this also leads to the overall poor rigidity of the tooling, which may cause some Assembly errors occur, and it is not suitable to use the same tooling for a long time. New tooling needs to be made to form consumables, which is not conducive to cost control and affects the overall production efficiency

The invention discloses a positioning and mounting method for an air branch pipe of a scavenging header supercharger, and relates to the technical field of diesel engines, in particular to an air branch pipe of a scavenging header supercharger. The air branch pipe comprises a scavenging header body, a supercharger body and an air branch pipe body; a scavenging header connecting flange is arranged at the top of the front end of the scavenging header body; a lower connecting flange is arranged at the bottom of the air branch pipe body; a limiting block is fixedly mounted outside the air branch pipe body; and a penetrating bolt is sleeved with the limiting block in a threaded mode. According to the positioning and mounting method for the air branch pipe of the scavenging header supercharger, a limiting plate is mounted on the air branch pipe body, meanwhile, the reference of the limiting plate is adjusted through the penetrating bolt, an upper connecting flange and the lower connecting flange of the air branch pipe can be accurately connected with an air outlet of the supercharger body and a corrugated pipe, a previous tool manufacturing method is replaced, mounting errors caused by poor rigidity of the tool are reduced, the cost is reduced, production is guaranteed more efficiently, and more economic benefits are brought.
Description
technical field [0001] The invention relates to the technical field of diesel engines, in particular to a method for positioning and installing an air branch pipe of a scavenging manifold supercharger. Background technique [0002] The marine diesel engine is the heart of the ship, and the scavenging manifold is an important part of the air system of the diesel engine, which occupies a very important position in the operation of the diesel engine. The air system of the diesel engine is composed of the scavenging manifold, the exhaust manifold, the air cooler and the supercharger. Due to the influence of the structural layout, the air branch connecting the supercharger and the scavenging pipe exists in the form of a separate component, so the increase The precise installation of compressor air branch pipes has always been a key issue to be solved. [0003] When installing the air branch pipe of the supercharger in the past, the air branch pipe of the supercharger was made in...
