Welding device for oil injector support plate and round tube

Abstract

The invention relates to a welding device for an oil injector support plate and a round tube. The welding device comprises a bottom plate (1), a round tube fixing groove (2), a support plate press plate (3), air cylinders (4), pressers (5) and welding guns (6), wherein the round tube fixing groove (2) is fixed on the bottom plate (1), the support plate press plate (3) is arranged above the round tube fixing groove (2), the air cylinders (4) are in transmission connection with the pressers (5), and the welding guns (6) are aligned to the to-be-welded support plate and the to-be-welded round tube; the support plate is placed after the round tube is placed into the round tube fixing groove (2), the support plate is tightly pressed by the support plate press plates (3), meanwhile, the round tube is tightly pressed by the pressers (5), and the welding guns (6) are aligned to the support plate and the round tube to perform welding. Compared with the prior art, the welding device has the advantages of high welding efficiency, high product welding quality, safety, reliability and the like.

Description

technical field [0001] The invention relates to a fuel injector manufacturing technology, in particular to a welding device for a fuel injector support plate and a round pipe. 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, so the connection between the bracket plate and the round tube needs to be very accurate and firm, but the ex...

Problems solved by technology

[0003] As far as its characteristics are concerned, the fuel injector is a high-precision component, so the connection between the bracket plate and the round tube needs to be very accurate and firm, but the existing bracket plate and round tube welding devices generally have inaccurate positioning , poor welding points and other defects, causing the bending of the bracket plate, resulting in the unqualified size of the entire part, resulting in low quality injector products and low production efficiency
