After the shift fork retainer ring 55 is placed, the push cylinder 30 drives the push plate 41 to drive the shift fork retainer ring 55 into the correct position, so that the shift fork retainer ring 55 is snapped into the locking pin at the top of the product 4. Then, the first stop pin 46 is driven by the lower stop pin cylinder 43 to lock the transition tooling device 5. The locking pin at the top of the product 4 is clamped by the jaw 19 of a jaw cylinder 18, and then pulled backward by the push cylinder 30 to test whether the shift fork retainer ring 55 is firmly clamped. After the test is completed, the jaw cylinder 18 drives the locking pin at the top of the product 4 to retract. At this time, the push cylinder 30 of the shift fork retainer ring 55 drives the transition tooling device 5 to retract completely. Then, the rear electric cylinder 8 drives the jaw cylinder 18 to lift the movable part at the top of the product 4 (i.e., the locking pin at the top of the product 4) upward and then lower it to test whether the force value during the up and down movement after the shift fork retainer ring 55 is snapped in is correct, so as to confirm whether the shift fork retainer ring 55 is completely and correctly installed and whether the process tooling is completely removed.

The thin shaft end passes through the second spring 68 and is inserted into the stepped vertical pin hole 61 from below the tooling body. The guide shaft 59 is a stepped shaft. One end of the thin shaft passes through the first spring 64 and is installed in the second tooling horizontal hole 70 of the tooling body, so that the large semi-circular head of the second stop pin 67 abuts against the plane of the guide shaft 59. There is a round hole at the perpendicular axis of the guide shaft 59, and a pin is tightly fitted for stroke limitation.

[0061] The working principle of the present invention:

[0062] Under normal conditions, the electric cylinder 8 is in the retracted state, the jaw cylinder 18 is in the open state, the push cylinder 30 / the punch cylinder 27 / the stop pin cylinder 43 are in the retracted state, the clamping cylinder 52 is in the extended state, and the second stop pin 67 and the guide shaft 59 are in the retracted state under the action of the springs.

[0063] The transition tooling device 5 has been installed on the product 4. After the product is positioned, the shift fork retaining ring 55 is placed on the transition tooling device 5. Then, the clamping cylinder 52 retracts to clamp the bottom of the product 4, and the jaw cylinder 18 drives the jaws 19 to close to maintain the position of the product. The pushing cylinder 30 extends, driving the pushing plate 41, L-shaped mounting seat 42, punch cylinder 27, punch 44, stop pin cylinder 43, and the first stop pin 46 forward. First, the shift fork retaining ring 55 is pushed into place. Then, the stop pin cylinder 43 is used to push the first stop pin 46 to extend and insert it into the insertion pin hole 62, so that the transition tooling device 5 and the assembly and test device 2 are integrated. Then, the punch cylinder 27 drives the punch 44 to extend to push the guide shaft 59 to compress the first spring 64 so that the mandrel touches the left side groove edge, and the inclined surface (i.e., the slope 65) of the guide shaft 59 is used to drive the second stop pin 67 to compress the second spring 68 so that the second stop pin 67 extends, so that the second stop pin 67 is inserted into the retaining ring pin hole 69 of the shift fork retaining ring 55. At this time, the pushing cylinder 30 makes a retracting action to confirm whether the shift fork retaining ring 55 has been clamped in place. If the pushing cylinder 30 retracts completely at this time, the assembly of the shift fork retaining ring 55 fails. If the pushing cylinder 30 does not retract, the installation of the shift fork retaining ring 55 is successful. At this time, the pushing cylinder 30 makes an extending action (to facilitate the retraction of the second stop pin 67), then the punch cylinder 27 retracts, and the guide shaft 59 retracts under the action of the first spring 64 until the mandrel 63 touches the right side groove edge, and the second stop pin 67 drops below the plane under the action of the second spring 68. At this time, the shift fork retaining ring 55 is completely separated from the transition tooling device 5. The pushing cylinder 30 retracts completely with the transition tooling device 5, and the stop pin cylinder 43 retracts with the first stop pin 46. The shift fork retaining ring 55 is in a free state. Then, the electric cylinder 8 drags the beam plate 16, floating plate 17, jaw cylinder 18, and the moving part at the top of the product 4 to rise and then fall, and the first sensor 14 is used to test whether the force value during the up and down movement after the shift fork retaining ring 55 is clamped is correct, so as to confirm whether the shift fork retaining ring 55 is completely and correctly installed and whether the process tooling is completely removed. After the test is completed, the jaw cylinder 18 drives the jaws 19 to open together with the limiting parts, the first limiting plate 21 and the second limiting plate 22.

[0064] After the present invention adopts the shift fork retaining ring assembly and pull-off test device, there will no longer be problems such as missing installation, wrong installation, and cumbersome testing, thus improving the yield rate of products and the efficiency.
