Specifically, the following are mentioned: the output end of the clamp spring hydraulic driving piece 29 is coaxially arranged with the discharge hole 28.

In practical operation, after the workpiece a is completely pressed at the previous station, the workpiece a is continuously conveyed forward to the station of the first snap spring press 26 by the belt conveyor 15. The clamp spring in the guide channel moves downwards to the discharge hole 28 due to gravity to realize positioning, and then the clamp spring hydraulic driving part 29 makes an extending movement and pushes the clamp spring to be pressed on a workpiece, so that a clamping effect is realized.

Further, a fixing plate 30 is arranged at the upper end of the clamp spring hydraulic driving part 29, a sliding groove 31 penetrates through one side of the fixing plate 30, and a push plate 32 is slidably connected in the sliding groove 31.

Finally, the screw slide rail conveyor 36 drives the moving seat 37 to move until the cross shaft on the workpiece a and the clamping hole 61 on the bearing sleeve correspond to the discharge hole of the second vibration disc 40, and at this time, the screw slide rail conveyor 36 stops running. Finally, the bearing is pushed into the clamping hole 61 by the second hydraulic cylinder 41, so that the inner surface and the outer surface of the bearing respectively generate interference fit with the inner walls of the clamping holes 61 on the cross shaft and the bearing sleeve to form the cross shaft assembly by press fitting.

In addition, the sixth driving member controls the second movable arm 49 to move up and down to be used in cooperation with the second jaw 51. The linkage and the matching between the structures jointly complete the transfer of the workpiece A on the first press-mounting machine 4 to the second press-mounting machine 5. In addition, this application still can realize floating connecting plate 50 and second clamping jaw 51 upset 90 degrees through the concertina movement who drives actuating cylinder 53, makes work piece A its position state also can overturn 90 degrees when transporting to second pressure equipment machine 5 on to better cooperate with limiting plate 38 and gag lever post.
