Embodiment

[0018] Such as figure 1 and figure 2 As shown, a welding device for injector joints and round pipes includes a base 1, a round pipe fixing groove 2, a joint hoop 3, a joint push rod 4, a cylinder 5 and a compactor 6. The round The pipe fixing groove 2 is fixed on the base 1, the joint hoop 3 is installed at both ends of the round pipe fixing groove 2, and the joint ejector rod 4 is installed on the upper part of the round pipe fixing groove 2, and is connected with the cylinder 5 through transmission;

[0019] After the round pipe is put into the round pipe fixing groove 2, the compactor 6 is connected with the round pipe, and at the same time, the joint hoop 3 is tightened, and the joint is put into the joint hoop 3, and the cylinder 5. The control joint mandrel 4 falls down and tightens the joint and the round pipe.

[0020] There are two joint hoops 3, which are symmetrically arranged at both ends of the round pipe fixing groove 2. There are two joint push rods 4 and cy...

Abstract

The invention relates to a welding device for joints and a round tube a fuel injector. The welding device comprises a base (1), a round tube fixing groove (2), joint hoops (3), joint ejection rods (4), cylinders (5) and pressers (6), wherein the round tube fixing groove (2) is fixed on the base (1); the joint hoops (3) are mounted at two ends of the round tube fixing groove (2); the joint ejection rods (4) are mounted at the upper part of the round tube fixing groove (2) and in transmission connection with the cylinders (5); and after the round tube is placed in the round tube fixing groove (2), the pressers (6) and the round tube are in pressed connection, simultaneously, the joint hoops (3) are tightened, the joints are placed in the joint hoops (3), and the cylinders (5) control the joint ejection rods (4) to drop down to tightly eject the joints and the round tube. Compared with the prior art, the welding device has the advantages that the device is safe, reliable and accurate in positioning, the product quality and the work efficiency are improved and the like.

Description

technical field [0001] The invention relates to a fuel injector production equipment, in particular to a welding device for a fuel injector joint 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 its joint and the round pipe needs to be very accurate and firm, but the existing joint and rou...
