[0039] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0040] like Figures 1 to 20 As shown, a fuel injector detection device of this embodiment is used for detecting the fuel injector 10, including detecting the large end surface 101, large outer circle 102, shoulder surface 103, small outer circle 104 and ball head surface 105 of the fuel injector 10.

[0041] The fuel injector inspection device of this embodiment includes an inspection assembly and a conveyor 3. The conveyor 3 is used to carry the fuel injectors, enabling them to be transferred between the various inspection assemblies. The conveyor 3 in this embodiment is a graduated disk, a conventional disc-shaped rotating device. The fuel injectors are rotated and transported by the conveyor 3. The inspection assembly is located downstream of the feed assembly 1. The feed assembly 1 includes several feed channels 11, within which the fuel injectors are arranged. The fuel injectors are automatically fed into the feed channels 11 using a feeding device such as a vibrating plate. This embodiment has five feed channels. By feeding multiple parallel feed channels simultaneously, feeding efficiency can be improved. A rotating transport assembly 2 is located between the feed assembly 1 and the conveyor 3. The rotating transport assembly 2 transports the fuel injectors onto the conveyor 3, enabling automatic placement of the injectors. The inspection assembly includes a small outer circle detection assembly 4, located outside the conveyor 3, for detecting the small outer circle of the fuel injectors. A shoulder surface detection assembly 5, located outside the conveyor 3, for detecting the shoulder surface of the fuel injectors. The spherical head surface detection component 6 is arranged on the outside of the conveying device 3 and is used to detect the spherical head surface of the fuel injector. The large end surface detection component 7 is arranged on the outside of the conveying device 3 and is used to detect the large end surface of the fuel injector. The unloading component 8 is arranged on the outside of the conveying device 3 and is used to remove the fuel injector on the conveying device 3. The above-mentioned detection components are arranged on the circumference of the conveying device 3 in sequence, and the fuel injector is passed through each detection component for detection through the rotation of the conveying device 3. The small outer circle detection component, the shoulder surface detection component and the spherical head surface detection component all include a detection mechanism, a driving mechanism and a clamping mechanism. The driving mechanism is connected to the clamping mechanism, and the driving clamping mechanism drives the clamping mechanism to move between the detection mechanism and the conveying device. The clamping mechanism is used to clamp the fuel injector on the conveying device 3. In the above technical solution, the fuel injector can be automatically transported to the conveying device 3 through the feeding component 1 and the rotating conveying component 2, and the fuel injector is circulated between the various detection components through the conveying device 3. The small outer circle detection assembly, shoulder surface detection assembly, ball head surface detection assembly, and large end surface detection assembly can be used to inspect various parts of the fuel injector, providing a comprehensive inspection of the fuel injector and improving the inspection effect. Each detection assembly is equipped with a detection mechanism, a drive mechanism, and a clamping mechanism. Each detection mechanism can independently obtain the fuel injector from the conveyor device 3 for inspection and return it to the conveyor device 3 after inspection. This facilitates independent inspection by each detection mechanism without interfering with each other. The position of each detection assembly can be adjusted according to the different inspection processes of different fuel injectors, making inspection more flexible.

[0042] In this embodiment, the gripper mechanism includes at least two gripper modules, and the detection mechanism includes at least two detection modules. The two gripper modules synchronously grip the fuel injectors and perform detection on the corresponding detection modules. This technical solution enables each detection assembly to simultaneously grasp and detect more than two fuel injectors, thereby improving detection efficiency.

[0043] In this embodiment, the fuel injector detection device also includes a cleaning component 9, which includes a material blocking cylinder 91, a material blocking plate 92 and an air knife 93. The material blocking cylinder 91 is connected to the material blocking plate 92 to drive the material blocking plate 92 to open or block the feed channel 11 of the feed component 1, and the air outlet of the air knife 93 is facing the feed channel 11. Through the above technical solution, the air flow of the air knife 93 can blow away the oil on the fuel injector during the feeding process, avoiding affecting subsequent detection. During cleaning, the material blocking cylinder 91 drives the material blocking plate 92 downward to block the fuel injector, and the air knife 93 blows air; after completion, the material blocking plate 92 moves upward, allowing the fuel injector to continue moving forward. An oil receiving pan 94 is provided below the feed component 1, and an oil outlet 95 is provided above the oil receiving pan 94. The oil outlet 95 is located at the bottom of the feed channel 11 and is connected to the feed channel 11. The oil blown off from the oil nozzle 10 enters the feed channel 11 and is discharged into the oil receiving pan 94 through the oil outlet 95, so as to facilitate the collection and discharge of the oil.

[0044] In this embodiment, the rotating conveying assembly 2 includes a rotating arm 21, and a clamping mechanism 22 is symmetrically arranged on both sides of the rotating arm 21. The clamping mechanism 22 includes a plurality of clamping modules 23. Through the above technical solution, the fuel injector can be clamped by the clamping module 23. Each clamping mechanism 22 is provided with two clamping modules 23, which can clamp two fuel injectors synchronously. The clamping module 23 can use a cylinder clamp. The clamping module 23 is lifted and lowered by driving the cylinder 24. The rotating arm 21 is driven to rotate by the motor 25, so that the two clamping mechanisms 22 can reciprocate between the conveying device 3 and the feeding assembly 1, and continuously take the fuel injector on the feeding assembly 1 and put it on the conveying device 3.

[0045] In this embodiment, the small outer circle detection assembly 4 includes a detection mechanism 40, a positioning assembly 41, a clamping assembly 42, and a clamping mechanism 43. The clamping assembly 42 is arranged above the clamping mechanism 43, and the positioning assembly 41 is located below the clamping assembly 42. The clamping mechanism 43 is connected to a driving mechanism 45. The driving mechanism 45 drives the clamping mechanism 43 to clamp the fuel injector 10 and then place it vertically on the positioning assembly 41. The fuel injector 10 is positioned by the clamping assembly 42. The detection mechanism is arranged on the side of the positioning assembly 41. The detection mechanism includes a detection camera 44, which is oriented towards the small outer circle 104 of the fuel injector 10. The positioning assembly 41 includes a positioning seat 411, a driven wheel 413, and a driver 415. The positioning seat 411 is arranged below the clamping assembly 42. The positioning seat 411 has a fan-shaped positioning surface 412 that supports the fuel injector. A driven wheel 413 is provided below the positioning seat 411. The driven wheel 413 is connected to the driving wheel 416 of the driver 415 via a transmission belt 414. The driver 415 drives the positioning seat 411 to rotate. In the above technical solution, the clamping mechanism 43 obtains the fuel injector from the conveying device 3 and places it on the positioning assembly 41. The clamping assembly 42 can position the fuel injector so that it can remain stable during rotation. The detection camera 44 captures an image of the small outer circle and then performs identification and detection. The provision of the fan-shaped positioning surface 412 can make the fuel injector more stable during rotation.

[0046] In this embodiment, the pressing assembly 42 includes an ejector cylinder 421, a transmission mechanism, a spindle 423, a spindle spring 424, and an ejector 425. The ejector 425 is disposed in a cavity within the spindle 423 and presses against the ejector spring 426. The ejector cylinder 421 is connected to the spindle 423 via the transmission mechanism, driving the spindle 423 to move axially. The spindle spring 424 is sleeved on the spindle 423. In the above technical solution, when the fuel injector is pressed, the ejector cylinder 421 is pressed downward, causing the spindle 423 to move downward, driving the ejector 425 downward to press against the fuel injector 10, so that the fuel injector 10 can be positioned on the positioning assembly 41.

[0047] In this embodiment, the transmission mechanism includes a ram 48 and a needle roller thrust bearing 49. The telescopic rod 422 of the ejector cylinder 421 is connected to the ram 448, and the needle roller thrust bearing 49 is disposed between the spindle 423 and the ram 426. The telescopic rod 422 drives the ram 426 to cause axial movement of the spindle. The ram 48 is in a floating connection with the spindle, allowing the spindle to rotate relative to the ram 426. A linear bearing 47 is disposed below the needle roller thrust bearing 49, and the spindle 423 is disposed within the linear bearing 47. A self-lubricating bushing 429 is disposed below the linear bearing 47, and the spindle 423 is disposed within the self-lubricating bushing 429 to facilitate spindle movement. The spindle 423 has an opening 427 at its end, which has an inverted tapered surface 428. The ejector pin 425 is inserted into the opening 427 and coaxially arranged with the spindle 423. The end of the ejector pin 425 is inserted into the injector nozzle, with the inverted tapered surface 428 pressing against the injector nozzle's large end face 101. When positioning the injector nozzle, the ejector pin 425 first presses against the injector nozzle. As the spindle descends, the inverted tapered surface 428 of the opening 427 presses against the nozzle's large cross-section, tightening and centering the nozzle. During testing, the injector nozzle and the spindle rotate synchronously.

The adjustment block 501 is connected to the detection assembly 40, and the adjustment member 502 is threadedly connected to the adjustment block 501.
