Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-6 , an automobile fuel injection pipe detection device and its detection method, including a detection table 1, a support frame 2 and a water outlet 3.

The inner side of the connecting block 114 is threadedly connected to the outer surface of the threaded rod 113. The threaded rod 113 is connected to the support plate 111 through a bearing. The two ends of the first connecting rod 115 are respectively fixedly connected to the bottom of the connecting block 114 and the top of the first clamp 116. The outer surface of the first connecting rod 115 is slidably connected to the inner side of the support plate 111. A notch adapted to the connecting block 114 is opened on the inner side of the support plate 111. The connecting block 114 is slidably connected to the support plate 111. The second clamp 117 is installed at the position corresponding to the first clamp 116 on the top of the detection table 1. The gasket 118 is installed in the notches on the inner sides of the first clamp 116 and the second clamp 117. The gasket 118 is connected to the first clamp 116 and the second clamp 117 through a colloid.

[0033] During use, the position of the plug 216 is adjusted. When the plug 216 moves between the two sets of gaskets 118, the automotive fuel injection pipe is sleeved on the automotive fuel injection pipe. The driving motor 112 is started, and the driving motor 112 drives the threaded rod 113 to rotate. When the threaded rod 113 rotates, it drives the connecting block 114 to slide inside the support plate 111. When the connecting block 114 moves up and down, the connecting block 114 drives the clamp 116 to move up and down through the connecting rod 115. When the clamp 116 drives the gasket 118 to move down, the clamp 116 drives the gasket 118 to press the automotive fuel injection pipe against the gasket 118 inside the clamp 117, thereby stably clamping and fixing the automotive fuel injection pipe, making the automotive fuel injection pipe more stable during detection; through the adjustment of the threaded rod 113 on the connecting block 114, the clamp 116 can clamp the automotive fuel injection pipe more firmly without shaking.

[0034] The adjusting mechanism includes a fixed block 211, a fixed frame 212, an electric cylinder 213, a connecting rod 214, a connecting piece 215 and a plug 216. The fixed block 211 is welded to the back side of the detection table 1, the fixed frame 212 is welded to the back side of the fixed block 211, the electric cylinder 213 is installed on the back side of the fixed frame 212, one end of the connecting rod 214 is fixedly connected to the output end of the electric cylinder 213, the other end of the connecting rod 214 is fixedly connected to the back side of the connecting piece 215, the plug 216 is installed at one end of the connecting piece 215 away from the connecting rod 214, the outer surface of the connecting piece 215 is slidably connected to the inside of the fixed block 211, and a detection groove 218 is opened at the top of the detection table 1, and a clamping block 219 is fixedly connected to the inside of the detection groove 218 by bolts.

[0035] During use, the connector 217 is connected to an external air source. The operator starts the electric cylinder 213, and the electric cylinder 213 drives the connecting piece 215 to slide inside the fixed block 211 through the connecting rod 214. The connecting piece 215 drives the plug 216 to move. By adjusting the position of the plug 216, when the plug 216 moves between the two sets of gaskets 118, the automotive fuel injection pipe is sleeved on the automotive fuel injection pipe, making it convenient to install the automotive fuel injection pipe. At the same time, after the automotive fuel injection pipe is clamped by the gasket 118, the position of the plug 216 is further adjusted. When the plug 216 approaches the automotive fuel injection pipe, the two ends of the automotive fuel injection pipe can be pressed, making the connection of the automotive fuel injection pipe tighter, making the detection of the automotive fuel injection pipe more accurate, and the water in the detection groove 218 can be discharged from the water outlet 3.

[0036] The method for detecting an automotive fuel injection pipe includes the following steps:

[0037] S1. The connector 217 is connected to an external air source through a hose, an appropriate amount of water is injected into the detection groove 218, the position of the connecting piece 215 is adjusted, the connecting piece 215 drives the plug 216 to approach the direction of the clamp 117, the plug 216 moves to a suitable position, and then the two ends of the fuel injection pipe are sleeved outside the two plugs 216.

[0038] S2. Adjust the height of fixture 116. Fixture 116 drives the spacer 118 to move downward. Fixture 116 presses the fuel injection pipe against the spacer 118 inside fixture 117 through the spacer 118 to fix the fuel injection pipe.

[0039] S3. Adjust the height of fixture 116. Fixture 116 drives the spacer 118 to move downward. Fixture 116 presses the fuel injection pipe against the spacer 118 inside fixture 117 through the spacer 118 to fix the fuel injection pipe.

[0040] S4. Press the fuel injection pipe inside the clamping block 219.

[0041] S5. Start the air source connected to the automotive fuel injection pipe detection device. The gas passes through the connector 217 and the connecting piece 215 and enters the fuel injection pipe through the plug 216. Bubbles are generated in the fuel injection pipe immersed in water, indicating that the fuel injection pipe is damaged. Otherwise, the fuel injection pipe is not damaged.
