[0002] Traditional fuel system reliability analysis: Based on the accelerated test bench, the ultimate strength test and low-cycle fatigue life test of the main components are carried out, the life of each component is determined, and then the reliability is evaluated by the life. The evaluation of the service life of each component is relatively independent, and it is difficult to consider the coupling relationship between the components of the fuel system. The overall life and reliability evaluation of the fuel system is poor. Among them, the performance of the fuel valve mainly determines the reliability of the fuel system. When the fuel valve is tested, the fuel valve needs to be quickly positioned. Since the fuel valve itself has different models, the shape of its outer side is also different.

DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, Figure 1-Figure 3 The cam 13 is connected to the support 11 by a support column 12, and a mounting opening is provided in the middle position of the upper end of the positioning platform 13, and a rotating seat 15 is provided at the position of the mounting opening for rotation. The rotating seat 15 is connected to a rotating driving member for driving the rotation thereof, and a positioning module for positioning the fuel valve is provided at the upper end of the rotating seat 15, and the positioning module includes a slide groove 21 provided at the upper end of the rotating seat 15, and a clamping slide 22 is slidably provided in each slide groove 21, and the clamping slide 22 is connected to the slide groove 21 by a sliding member, and a clamping base 20 is provided at the upper end of each clamping slide 22, and a pressing member for pressing the outer side of the fuel valve is provided on the clamping base 20, and a plurality of clamping slides 22 are connected to a clamping pusher for driving them to converge in the middle, so that the plurality of pressing members can quickly position the outer side of the fuel valve, thereby facilitating the detection of the fuel valve;

[0022] The clamping pusher includes a transmission rod 24 arranged at the lower end of the clamping slide 22, and a pressure block 27 is provided at the lower end of each transmission rod 24. The bottom of each pressure block 27 is an inclined surface arranged outward, and a steel ball 26 is rotated in the spherical cavity on the inclined surface. A conical pressure piece 25 is provided upwardly arranged below the positioning platform 13, and the inner wall of the conical pressure piece 25 is pressed and contacted with the steel ball 26. The outer side of the conical pressure piece 25 is provided with a guide member for guiding it to move up and down. The lower end of the conical pressure piece 25 is connected to a threaded pusher for pushing it to move upward. Under the action of the threaded pusher, the conical pressure piece 25 slides upward along the guide member. When the conical pressure piece 25 moves upward, it generates an extrusion force on the steel ball 26. Since the conical pressure piece 25 is a cone with a larger upper part and a smaller lower part, when the conical pressure piece 25 moves upward, multiple transmission rods 24 will approach, thereby providing power for clamping;

[0023] The guide member includes a plurality of guide vertical rods 32 arranged on the outside of the conical pressure member 25. The upper and lower ends of the guide vertical rods 32 are respectively connected to the positioning platform 13 and the base 11. A guide sleeve 33 is slidably provided on each guide vertical rod 32. A connecting rod 31 for connecting to the conical pressure member 25 is provided on the outside of the guide sleeve 33. When the conical pressure member 25 slides, the guide sleeve 33 moves on the guide vertical rod 32, thereby ensuring the smoothness of the lifting;

[0024] The threaded pusher includes a pressing block 27 provided at the lower end of the conical pressing member 25. The lower end of the pressing block 27 is threadedly engaged with a lifting screw 30. The lifting screw 30 is connected to a lifting motor 29 for driving the lifting screw 30 to rotate. The lifting motor 29 is provided at the upper end of the base 11. Under the action of the lifting motor 29, the lifting screw 30 and the lifting column 28 rotate relative to each other. Under the action of the thread, the lifting column 28 slides upward along the lifting screw 30, thereby providing power for the conical pressing member 25 to rise and fall.

[0025] The pressing member includes a plurality of pressing rods 19 distributed on the clamping base 20. The outer end of each pressing rod 19 is provided with a surrounding plate 16. The surrounding plate 16 is fixedly connected to the surface of the clamping base 20 by a buffer spring 17. The end of the pressing rod 19 is provided with a pressing head 35. When pressing the outer side of the fuel valve, the end of each pressing rod 19 contacts the surface of the part. Due to the different flatness of the part surface, the extension range of the buffer spring 17 on each pressing rod 19 is also different. Therefore, the pressing surface formed by the multiple pressing heads 35 can better cooperate with the part surface, thereby ensuring the clamping and positioning effect.

[0026] The pressing head 35 is a pressing ball, which fits into the spherical cavity at the end of the pressing rod 19. When the pressing rod 19 presses against the surface of the part, the pressing ball rolls, thus preventing the surface of the part from being worn. It should be noted that the clamping and positioning method here cannot clamp flat plates and is only suitable for clamping irregular objects such as fuel valves.

[0027] The sliding member includes a T-shaped block arranged at the lower end of the clamping slide 22, and a limiting slide 18 that cooperates with the T-shaped block is provided in the slide groove opening 21, so that the clamping slide 22 can slide smoothly. The outer end of each clamping slide 22 is connected and fixed to the inner wall of the slide groove opening 21 by a return spring 23.

[0028] The rotary drive member includes a driven gear ring disposed outside the rotating seat 15, the driven gear ring meshing with the driving gear 14. The lower end of the driving gear 14 is connected to an adjustment motor 34 for driving the driving gear 14 to rotate. The adjustment motor 34 drives the driving gear 14 to rotate, and the driving gear 14 drives the rotating seat 15 to rotate via the driven gear ring, thereby adjusting the detection angle of the fuel valve.

[0029] The above embodiment discloses a rapid positioning device for fuel valve detection, wherein, in actual use, the conical pressing member 25 is first lowered by the threaded pusher. At this time, under the action of the return spring 23, the multiple clamping slides 22 will move away from the setting, and then the fuel valve to be detected is placed in the position to be fixed. Then, the conical pressing member 25 brought by the threaded pusher rises, and the conical pressing member 25 slides upward along the guide member. When the conical pressing member 25 moves upward, it will generate an extrusion force on the steel ball 26. Since the conical pressing member 25 is a cone with a larger upper part and a smaller lower part, the conical pressing member 26 is pressed downward. When moving upward, the multiple transmission rods 24 will approach each other, thereby providing power for clamping. The end of each pressure rod 19 contacts the surface of the part. Due to the different flatness of the part surface, the extension range of the buffer spring 17 on each pressure rod 19 is also different. Therefore, the pressing surface formed by the multiple pressure heads 35 can better cooperate with the part surface, thereby ensuring the clamping and positioning effect. After positioning is completed, the driving gear 14 can be driven to rotate by adjusting the motor 34. The driving gear 14 drives the rotating seat 15 to rotate through the driven gear ring, thereby adjusting the detection angle of the fuel valve.

[0030] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
