The left side of mechanism 31, the servo motor 22-2-9 work of fuel injector feed mechanism 22, drives pneumatic chuck 22-2-12 and fuel injector
10 rotate always in the horizontal plane, and the servo electric jar 31-4-6 of oil spout take over feed mechanism 31 starts to work and push rod
31-4-7 is moved downward, and the impulse stroke of the push rod 31-4-7 by setting servo electric jar 31-4-6 makes machine frame 31-5-1
With moving downward until the center line of the whelk hole 10-1 of fuel injector 10 is with V-arrangement positioning device 31-5-7's for push rod 31-4-7
The center line of positioning pin 31-5-7d overlaps in same level plane, at this time push rod 31-4-7 reach setting impulse stroke and
It is stopped, servo electric jar 31-4-1 horizontal at this time starts to work and the tooling backboard 31- in push rod 31-4-2 promotions left side
4-5 and machine frame 31-5-1 is moved towards the direction of fuel injector 10, until the V-type opening of V-arrangement positioning device 31-5-7 clamps
The positioning pin 31-5-7d of the just stop motion of 10 upper part of fuel injector, V-arrangement positioning device 31-5-7 moves right with respect to origin-location
It is dynamic, until the center line of the center line of the whelk hole 10-1 of the fuel injector 10 of rotation and positioning pin 31-5-7d are on the same axis,
Positioning pin 31-5-7d is moved downward and is entered in the 10-1 of whelk hole under the thrust of spring 31-5-7c at this time, at this time servo motor
Automatically correcting for the whelk hole 10-1 of fuel injector 10 is completed in 31-4-6 stop motions.
After the whelk hole 10-1 of fuel injector 10 is automatically corrected, the push rod 31-4-2 of horizontal servo electric jar 31-4-1 drives
Machine frame 31-5-1 resets, and moves right to initial position, and then the push rod 31-4-7 of servo electric jar 31-4-6 drives tooling
Frame 31-5-1 moves up to initial position, and fuel injector feed mechanism 22 is downward by fuel injector 10 at this time, and indentation cylinder head 12 is right
The mounting hole of oil sprayer 12-3 answered, and move up to original state, so complete fuel injector 10 automatically correct and erector
Make.
Referring to Fig. 2, Fig. 3, Figure 20 and Figure 21, in the mounting hole of oil sprayer 12-3 that fuel injector 10 is mounted on cylinder head 12
Afterwards, by setting the impulse stroke of the push rod 31-4-7 of the servo electric jar 31-4-6 in oil spout take over feed mechanism 31, servo
The push rod 31-4-7 of electric cylinder 31-4-6 drives machine frame 31-5-1 to move downwardly to the center line until pneumatic chuck 31-5-6
It is overlapped in the horizontal plane with the center line of the oil spout take over mounting hole 12-4 of cylinder head 12, push rod 31-4-7 reaches setting at this time
Impulse stroke and be stopped, oil spout take over 11 is placed on pneumatic chuck 31-5-6 by operator, then horizontal servo
Electric cylinder 31-4-1 and servo motor 31-5-2 start to work, and the push rod 31-4-2 of servo electric jar 31-4-1, which drives, is equipped with oil spout
The machine frame 31-5-1 of take over 11 is moved downward, and servo motor 31-5-2 drives oil spout take over 11 to rotate, servo-electric
Cylinder 31-4-1 and servo motor 31-5-2 is worked together until the screwed part in 11 front end of oil spout take over is screwed to cylinder
In the oil spout take over mounting hole 12-4 of lid 12, and the left end of oil spout take over 11 enters the whelk hole 10-1 of fuel injector 10 at this time
In, the final high-precision vertical degree installation for realizing fuel injector 10 and oil spout take over 11.
