[0115] In a further embodiment of the present invention, the specific implementation is as follows: Figure 1 As shown, when the tooling frame 1 is placed on the quick-change trolley 2, the non-return mechanism 22 locks the tooling frame 1 in a fixed position, and the steering mechanism 3 and the guide wheel 24 are used to guide and push the quick-change trolley 2 into the work station, and then the tooling frame 1 is lifted up to a position level with the positioning clamping mechanism 11 by the lifting mechanism 5. At this time, the non-return mechanism 22 is released, and the tooling frame 1 is pushed along the direction of the universal ball 25 and the guide wheel 26 until it hits the pin-resisting position on the positioning clamping mechanism 11; Figure 3 As shown, there is a track groove under the foot of the tooling frame 1, which is placed above the universal ball 25 of the quick-change trolley 2. The side of the bracket of the tooling frame 1 is tangent to the guide wheel 26 of the quick-change trolley 2. The quick-change trolley 2 realizes relative linear motion with the tooling frame 1 through the rotation of the universal ball 25 and the guide wheel 26; Figure 4 As shown, by rotating the steering hand wheel 31, the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the front steering wheel 23 to rotate through the rotating shaft 86. At the same time, the bevel gear set 87 above the front steering wheel 23 rotates, and the rear steering wheel 23 is driven to rotate through the rotating shaft 86. At the same time, the bevel gear set 87 above rotates, thereby realizing the synchronous steering function of the front and rear wheels; when the tooling frame 1 is placed directly above the quick-change trolley 2, the active wrench 88 is released, and the driven clamping plate 89 pops out under the action of the spring 9, and together with the fixed baffle 43, fixes a bracket of the tooling frame 1, as shown in FIG. Figure 7 As shown; when it is necessary to separate the tooling frame 1 from the quick-change trolley 2, pull back the active wrench 88 with force, driving the driven card plate 89 to retract against the force of the spring 9. After the card plate 89 retracts, the bracket of the tooling frame 1 is released, and the two can perform relative linear motion, such as Figure 8 As shown; the guide wheel 24 on the quick-change trolley 2 cooperates with the guide plate 41 to make the quick-change trolley 2 enter the workstation in the correct direction. After the bumper 82 at the end of the quick-change trolley 2 pushes against the baffle 43, the PLC controls the cylinder 44 to push the clamping block 14 to clamp the bumper 82 of the quick-change trolley 2. At this time, the quick-change trolley 2 is clamped and fixed as a whole; when the quick-change trolley 2 is not in place (i.e., has not entered the workstation), the state of the push pin 83 is as shown Fig.11 As shown: at this time, the left end of the ejector pin 83 is not stressed, the spring 9 pushes up the guide rod 84 and the lock rod 74, and the tooling frame 1 is stuck by the lock rod 74 and cannot be pushed out, thus achieving locking; when the trolley is in place (i.e., enters the work station), the state of the ejector pin 83 is as follows Fig.12As shown: at this time, the collision block 82 hits the end surface of the positioning clamping mechanism 11, and the ejector pin 83 retracts to the right after being forced, pushing the right end of the guide rod 84 downward, driving the head of the locking rod 74 downward (i.e., the limit is invalid), and the tooling frame 1 can be pushed out; the positioner side air pipe mounting plate 61 is placed on the positioning clamping mechanism 11, and the fixture side air pipe mounting plate 62 is placed on the tooling frame 1, as shown in FIG. Fig.13 As shown, after the tooling frame 1 is in place, the push-pull rod 72 is manually pushed, and under the guidance of the guide block 7 and the guide shaft 63, the insertion tube 64 is accurately inserted into the trachea joint 67, and the current plug is inserted into the first current plug seat 65 and the second current plug seat 66. After being inserted tightly, the locking rod 74 is pulled to the eccentric positioning pin 73 to lock the device, as shown in FIG.
