[0104] When assembling the bearing, the material picking mechanism 2 44 clamps the transmission shaft and places it in the groove of the positioning seat 1 4121, and then the support push cylinder 4124 and the lifting cylinder 1 4125 are started to align the support block 4126 with the positioning seat 1 4121 to support the suspended end of the transmission shaft, and then the rotary pressing cylinder 1 4122 is started to drive the pressing plate 1 4123 to press the transmission shaft, and the transmission shaft is completely positioned. At the same time, the bearing loading assemblies 414 on both sides of the positioning assembly 412 are loaded, and the bearings slide into the arc-shaped opening grooves 41331 of the corresponding press-fitting assemblies 413 through the guide slide grooves 41451 on the guide seat 4145. The press-fitting assemblies 413 on both sides can be started at the same time and move toward the middle positioning assembly 412 to press the bearings on the press-fitting blocks 4133 on both ends of the transmission shaft. After the press-fitting is in place, the bearing press-fitting cylinder 4131 retreats. While the bearing press-fitting cylinder 4131 retreats, the check cylinder 4135 extends out to press against the bearing to prevent the retreat from driving the bearing backward, thus completing the press-fitting of the bearing on the transmission shaft; then the material taking mechanism 2 44 takes out the semi-finished product of the transmission shaft integrated component of the transmission shaft and transports it to the end cover press-fitting mechanism 42. In addition, it should be noted that the structures of the multiple bearing press-fitting mechanisms in the present invention are similar, and the multiple end cover press-fitting mechanisms are similar, except that the positioning structures and press-fitting strokes corresponding to different transmission drawers are different.
