Description

Technical Field

[0001] This utility model specifically relates to a gearbox fuel injector quality testing device. Background Technology

[0002] The fuel injector itself is a normally closed valve (a normally closed valve means that the valve is always closed when there is no input control signal; while a normally open valve is always open when there is no input control signal), and the opening and closing of the valve is controlled by the up and down movement of a valve needle.

[0003] Fuel injectors require quality inspection after production, including the inspection of the fuel spray pattern. However, current inspection equipment cannot effectively determine the fuel spray pattern, resulting in inaccurate inspection. Utility Model Content

[0004] The purpose of this invention is to provide a gearbox fuel injector quality testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gearbox fuel injector quality detection device, comprising a base, a detection plate, a limiting component, a positioning frame, and an adjustment component. The detection plate is set on the surface of the base through the limiting component, and the fuel injector to be detected is set vertically above the detection plate through the positioning frame. The fuel injector adjusts the distance between the fuel injector and the detection plate through the adjustment component to adjust the fuel injection range.

[0006] Preferably, a rotating shaft is centrally disposed within the base, a support plate is disposed on the upper surface of the rotating shaft, and the limiting component includes a base disposed on the support plate, a support block is disposed on the base, and a threaded hole is formed in the support block.

[0007] Preferably, a screw is inserted laterally into the threaded hole, a movable seat is provided at one end of the screw, and a fixed seat adapted to the movable seat is provided on the base. The fixed seat and the movable seat are both provided with grooves for inserting the detection plate on their adjacent sides.

[0008] Preferably, a first handle is provided at the end of the screw away from the movable seat, a protruding strip extends inward from the surface of the base, and a slide rail adapted to the protruding strip is provided on the lower surface of the movable seat.

[0009] Preferably, the base is provided with a vertical rod, the positioning frame is mounted on the vertical rod via a lifting plate, the adjusting assembly includes a horizontal plate mounted on the vertical rod, a spring is provided between the lifting plate and the horizontal plate, and a scale is provided on the outer side of the horizontal plate.

[0010] Preferably, a first connecting arm is rotatably provided on the outer side of the cross plate, a second handle is provided on the first connecting arm, and a second connecting arm is rotatably provided in the middle of the first connecting arm.

[0011] Preferably, the end of the second connecting arm away from the first connecting arm is connected to the lifting plate.

[0012] The technical effects and advantages of this utility model are as follows: The gearbox injector quality inspection device places the injector to be inspected vertically in the positioning frame. Rotating the first handle drives the screw to rotate. As the slide rail slides along the length of the convex strip, the rotational motion is converted into linear motion, causing the moving seat to move towards the fixed seat and insert the inspection plate into the groove, thus fixing the inspection plate and positioning it vertically below the injector. Pressing the second handle, through the cooperation of the rotating first and second connecting arms, causes the lifting plate to move vertically downwards on the vertical rod. Different degrees of pressing result in different descent heights of the lifting plate, resulting in different areas of the injector spraying onto the inspection plate. By recording the distance on the scale, the spray pattern of the injector at different distances can be effectively and accurately detected. The overall structure is simple and easy to use.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] To facilitate adjustment of the distance between the fuel injector and the detection plate, refer to Figure 1 , Figure 2 and Figure 3 As shown, the system includes a base 1, a detection plate, a limiting component, a positioning frame 3, and an adjustment component. The detection plate is mounted on the surface of the base 1 via the limiting component. The fuel injector to be tested is positioned vertically above the detection plate via the positioning frame 3. The fuel injector's distance from the detection plate is adjusted via the adjustment component to regulate the fuel injection range. The fuel injector to be tested is placed vertically within the positioning frame 3. Rotating the first handle 12 causes the screw 8 to rotate. As the slide rail 14 slides along the length of the convex strip 13, the rotational motion is converted into linear motion, allowing the fuel injector to move. The seat 9 moves toward the fixed seat 10 and inserts the detection plate into the groove 11, thereby fixing the detection plate so that it is vertically below the nozzle. Pressing the second handle 21, through the cooperation of the rotating first connecting arm 2 and the second connecting arm 20, causes the lifting plate 17 to move vertically downward on the vertical rod 15. Different pressing degrees can cause the lifting plate 17 to descend to different heights, resulting in different areas of the nozzle spraying onto the detection plate. By recording the distance of the scale 19, the spray pattern of the nozzle at different distances can be effectively and accurately detected.

[0022] To facilitate the detection of the shape of the fuel injector spray at different distances, refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a rotating shaft 4 is centrally located within the base 1, and a support plate 5 is mounted on the upper surface of the rotating shaft 4. The limiting assembly includes a base 6 mounted on the support plate 5, a support block 7 mounted on the base 6, a threaded hole in the support block 7, a screw 8 inserted laterally into the threaded hole, a movable seat 9 at one end of the screw 8, and a fixed seat 10 adapted to the movable seat 9 mounted on the base 6. The fixed seat 10 and the movable seat 9 both have grooves 11 for inserting a detection plate on their adjacent sides. A through hole communicating with the threaded hole is located on the upper surface of the support block 7, and a positioning bolt 22 is inserted into the through hole. The surface of the positioning bolt 22 has threads adapted to the outer threads of the screw 8. When the detection plate is inserted into the groove 11, the movable seat 9 moves to the desired position, and the positioning bolt 22 is inserted into the through hole to fix the movable seat 9, thereby fixing the detection plate. A first handle 12 is provided at the end of the screw 8 away from the movable seat 9. A protrusion 13 extends inward from the surface of the base 6. A slide rail 14 adapted to the protrusion 13 is provided on the lower surface of the movable seat 9. When the first handle 12 is rotated, the screw 8 rotates, and slides along the length of the protrusion 13 through the slide rail 14, converting the rotational motion into linear motion, thus enabling the movable seat 9 to move on the base 6. A vertical rod 15 is provided on the base 1. The positioning frame 3 is set on the vertical rod 15 through a lifting plate 17. The adjustment assembly includes a horizontal plate 16 set on the vertical rod 15. A spring 18 is provided between the lifting plate 17 and the horizontal plate 16. After spraying is completed, the second handle 21 is released, and the elastic action of the spring 18 on the lifting plate 17 pulls the lifting plate 17 back to its initial position. The horizontal plate 16 is fixed. Furthermore, a scale 19 is provided on the outer side of the horizontal plate 16. When the lifting plate 17 descends, the descent distance can be recorded by the scale 19, thereby controlling the distance between the fuel injector and the detection plate for easy recording. A first connecting arm 2 is rotatably provided on the outer side of the horizontal plate 16. A second handle 21 is provided on the first connecting arm 2. A second connecting arm 20 is also rotatably provided in the middle of the first connecting arm 2. The first connecting arm 2 and the second connecting arm 20 are rotatably connected. The second connecting arm 20 and the adjusting plate are also rotatably connected. Therefore, when the second handle 21 is pressed, the lifting plate 17 can be slid on the vertical rod 15 with the cooperation of the first connecting arm 2 and the second connecting arm 20. The end of the second connecting arm 20 away from the first connecting arm 2 is connected to the lifting plate 17.

[0023] In use, first place the nozzle to be tested vertically in the positioning frame 3, rotate the first handle 12 to drive the screw 8 to rotate, and as the slide rail 14 slides along the length of the convex strip 13, the rotational motion is converted into linear motion, so that the moving seat 9 moves toward the fixed seat 10 and inserts the detection plate into the groove 11, thereby fixing the detection plate and placing it vertically below the nozzle. Press the second handle 21, and through the cooperation of the rotating first connecting arm 2 and the second connecting arm 20, the lifting plate 17 moves vertically downward on the vertical rod 15. Different degrees of pressing can make the lifting plate 17 descend to different heights, so that the area sprayed by the nozzle onto the detection plate is also different. By recording the distance of the scale 19, the spray pattern of the nozzle at different distances can be effectively and accurately detected.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
