Problems solved by technology

[0003] As far as its characteristics are concerned, the fuel injector is a high-precision component, especially the connection between the fuel injector seat and the round pipe. At present, the welding position of the fuel injector seat and the round pipe is not accurate, and the welding point is poor, resulting in The scrapping of the whole part increases the production cost and reduces the product quality

Abstract

The invention relates to a welding device for fuel injector bases. The welding device is used for welding the fuel injector bases and a round tube and comprises a bottom plate (1), cylinders (2), fixing pins (3), mandrels (4), guide rails (5), a top plate (6) and conductive blocks (7), wherein the cylinders (2) and the fixing pins (3) are mounted on the bottom plate (1); the conductive blocks (7) are mounted on the top plate (6) which is connected with the bottom plate (1) through the guide rails; and to-be-welded fuel injector bases are mounted in the fixing pins (3), the round tube is in positioning connection with the fuel injector bases through the mandrels (4), the conductive blocks (7) press the round tube for powered welding, after the welding, the cylinders (2) eject the top plate (6) out. Compared with the prior art, the welding device has the advantages of safety, reliability, stability and convenience in maintenance and the projection welding quality of a product is improved.

Description

technical field [0001] The invention relates to a fuel injector seat production device, in particular to a welding device for the fuel injector seat. Background technique [0002] Over the past few decades, fuel injectors have seen increasing use in spark-ignited automotive internal combustion engines and have largely replaced carburetors as the fuel metering device for the engine. In a typical multi-point fuel injection system for a multi-cylinder internal combustion engine, there is one injector per engine cylinder that is always ready to inject fuel into the intake air stream to be entrained in the combustion air entering the engine cylinders , so a typical four, six or eight cylinder engine today will have four, six or eight injectors. [0003] As far as its characteristics are concerned, the fuel injector is a high-precision component, especially the connection between the fuel injector seat and the round pipe. At present, the welding position of the fuel injector seat...
