The axis of the valve core transfer wheel 44 is parallel to the axis of the valve core relay positioning tube 38, so that the valve core in the valve core relay positioning tube 38 can completely enter the valve core transfer groove 43. It should be noted that the lower side wall of one end of the valve core relay positioning tube 38 is provided with a second leakage through hole. The valve core 2 at the front end entering the valve core relay positioning tube 38 is pushed by the valve core 2 behind to the end face of the valve core relay positioning tube 38. At this time, the valve core 2 is located on the side of the valve core transfer wheel 44. With the rotation of the valve core transfer wheel 44, the valve core 2 falls out of the second leakage through hole and is embedded in the valve core transfer groove 43. With the transfer of the valve core transfer wheel 44, the valve core 2 is transferred to the valve core clamping positioning member.

One side of the fourth transfer protective shell is fixedly connected to the other side of the second leakage through hole. The axis of the fourth transfer protective shell coincides with the axis of the valve core transfer wheel 44. The second transfer guide plate is in the shape of a circular arc plate. One side of the second transfer guide plate is fixedly connected to the other side of the third transfer protective shell, so that the valve core transfer wheel 44 can transfer the valve core 2 to the valve core clamping positioning member. The third transfer protective shell and the fourth transfer protective shell can prevent the valve core 2 from disengaging from the valve core transfer groove 43 during the transfer of the valve core 2 by the valve core transfer wheel 44.

[0073] It should be noted that the fourth transmission shaft 41 rotation power is driven by the valve core clamping positioning member or according to the need of another motor.

The second valve core clamping positioning member is symmetrically and parallelly distributed on the fourth support 52 of the second support 18 and the workbench 5 with the first valve core clamping positioning member. The valve core clamping transmission belt 46 of the second valve core clamping positioning member is correspondingly attached to the valve core clamping transmission belt 46 of the first valve core clamping positioning member, so that the valve core positioning groove 51 of the second valve core clamping positioning member simultaneously clamps and positions one valve core 2 with the valve core positioning groove 51 of the first valve core clamping positioning member. The valve core 2 is positioned in the circumferential direction in the two valve core positioning grooves 51 (the valve core can move in the axial direction in the two valve core positioning grooves 51), so that the axis of the valve core 2 coincides with the axis of the spring 1, and the valve core 2 is conveniently inserted into the inner ring of the spring 1. It should be noted that the fourth support 52 is in the shape of a plate, and the interval between the fourth support 52 and the second support 18 is greater than the interval between the third support 19 and the second support 18, so as to facilitate the installation of the valve core assembly on the second valve core clamping positioning member.

The first magnetic force coil is fixedly embedded in a helical groove on the inner wall of the valve core pushing seat, and the valve core pushing shaft is axially slidably embedded in the valve core pushing seat tube. When a positive direct current is applied to the first magnetic force coil to generate a magnetic field, the valve core pushing shaft is pushed to move forward to insert the free end of the cylindrical body 4 of the valve core 2 in synchronous movement into the spring 1; when a reverse direct current is applied to the first magnetic force coil to generate a magnetic field after insertion, the valve core pushing shaft is pulled to retract into the valve core pushing seat. Further, a plurality of valve core pushing pieces 58 are provided, and the plurality of valve core pushing pieces 58 are distributed at equal intervals on the assembly transmission belt 57, so that the plurality of valve core pushing pieces 58 correspond to the plurality of valve core positioning grooves 51 one by one. It should be noted that due to the presence of the second positioning ring, the cylindrical body 4 of the valve core 2 cannot be completely inserted into the spring 1, and the valve core 2 detection transfer piece needs to further clamp the valve core 2 and the spring 1 along the axial direction to complete the assembly of the fuel nozzle valve core. Alternatively, the valve core pushing piece 58 can also be a micro automatic telescopic rod to automatically extend into the valve core positioning groove 51 and insert the valve core pushing piece into the spring 1.

Further, the diameter of the valve core push rod 66 is smaller than the inner diameter of the spring 1. When the spring 1 is not inserted into the valve core 2, the valve core push rod 66 will be inserted into the spring 1, at this time, the pressure sensor connected between the valve core push rod 66 and the clamping shaft detects an axial pressure less than a predetermined value, at this time, the second magnetic coil is controlled to input reverse direct current to generate a magnetic field to shrink the clamping shaft into the clamping fixed tube, that is, the valve core push rod 66 is pulled out of the spring 1, so that the unqualified spring 1 naturally falls into the scrap collection box on the workbench 5, thereby playing the oil nozzle valve core detection role.

[0085] Further, the valve core push clamping piece is provided with four valve core push clamping pieces, which are distributed one by one on the four top ends of one lateral transmission support frame 60. Alternatively, the valve core push clamping piece can also be a micro electric push rod to meet the automatic telescopic requirement.

The axis of the second push clamping piece 67 coincides with the axis of the first push clamping piece 65. Further, the diameter of the spring push rod 68 is greater than the inner diameter of the spring 1 and smaller than the outer diameter of the spring 1, so as to be clamped at the end of the spring 1 in cooperation with the valve core push rod 66.

When the fuel nozzle valve core is missing the spring 1 or the valve core in the fuel nozzle valve core clamped by the valve core pushing clamping piece and the spring pushing clamping piece, it cannot be clamped by the valve core pushing clamping piece and the spring pushing clamping piece, so as to be released downward from the spring clamping positioning piece and then fall into the scrap collection box, so as to detect the fuel nozzle valve core.
