[0060] When performing press fitting, first put the bearing and the end cover into the first material storage barrel 107 and the second material storage barrel 110, align the first loading trough with the first material storage barrel 107, align the second loading trough with the second material storage barrel 110, the bearing at the bottom of the first material storage barrel 107 is in the first loading trough, and the end cover at the bottom of the second material storage barrel 110 is in the second loading trough. The bearing delivery cylinder 105 works to push the first push rod 106 to move, and the bearing is on the support plate 119. The first push rod 106 drives the bearing in the first loading trough to move to the press-fitting holding floating frame 1162. Since the support plate 119 moves with the first push rod 106, the bearing The bearings do not move relative to each other, so that the bearing is stably placed in the first loading groove and will not jump due to friction; the movable rod 120 moves in the second slide groove and the third slide groove together with the first push rod 106. When the first loading groove has not moved to the bearing positioning hole 1166, the movable rod 120 moves to one end of the third slide groove and rests on the end surface of the third slide groove, and the first push rod 106 continues to move relative to the movable rod 120 until the first loading groove moves to above the bearing positioning hole 1166 and is aligned with the bearing positioning hole 1166. At this time, the through groove moves to the convex block 1168, and the first push rod 106 can move normally and use the convex block under the setting of the inclined surface. The block 1168 pushes the third push rod 122 to move, and the third push rod 122 moves into the fixed groove to push the fixed block 121 out of the fixed groove. The first connecting spring 1202 pulls the support plate 119 to move so that the support plate 119 is removed from the bottom of the first loading groove, and the bearing in the first loading groove falls into the bearing positioning hole 1166. The bearing moves to the top of the bearing positioning hole 1166 and then falls into the bearing positioning hole 1166. At the same time, the first connecting spring 1202 is used to quickly move the support plate 119 away from the bottom of the first loading groove to ensure that the bearing falls into the bearing positioning hole 1166 in a vertical direction to prevent the bearing from tilting and getting stuck in the bearing positioning hole 1166. The bearing is placed in the positioning hole 1166 to ensure the position of the bearing; the bearing delivery cylinder 105 drives the first push rod 106 to retreat, the bearing shaping cylinder 117 moves to the top of the bearing positioning hole 1166, the bearing shaping cylinder 117 pushes the bearing to move into the bearing positioning hole 1166, and pushes the bearing onto the positioning rod 1167, then the first push rod 106 is reset, and the support plate 119 moves in the first movable groove as the first push rod 106 moves back, the support plate 119 abuts against the support block to make the first push rod 106 move relative to the support plate 119, until the fixed block 121 moves to the fixed groove position to complete the reset of the support plate 119 and the first push rod 106;The end cover delivery cylinder 112 pushes the second push rod 111 to move, and the end cover in the second material loading trough moves to the press-fitting holding floating frame 1162. At this time, the end cover is aligned with the stopper positioning floating ring 1165, and the press-fitting cylinder 109 works to press the end cover downward, so that the end cover stop on the end cover is buckled on the stopper positioning floating ring 1165, and the end cover is positioned on the stopper positioning floating ring 1165. The press-fitting holding floating frame 1162 moves downward relative to the press-fitting bottom plate 1161 under the action of the press-fitting cylinder 109, and the press-fitting of the rear end cover and the bearing is completed after reaching the specified depth. The end cover and the bearing after press-fitting are as shown; Fig.16 As shown; at this time, the press-fitting cylinder 109 moves upward and resets, the third reset spring pushes the press-fitting retaining floating frame 1162 to reset upward, the pushing cylinder 113 pushes the third slider 115 to move, and the third slider 115 drives the end cover delivery cylinder 112 and the second push rod 111 to move together, and the second push rod 111 continues to move forward, and the end cover to be press-fitted is removed from the press-fitting tooling 116 and the press-fitted end cover directly falls on the assembly line. At this time, the pushing cylinder 113 and the end cover delivery cylinder 112 reset, completing a press-fitting process.

[0061] Since the bearing itself is relatively light, the bearings stacked in the first storage barrel 107 may get stuck and difficult to fall out. Therefore, when the first push rod 106 moves, the groove 1061 intermittently moves to the side of the push block 128. When the push block 128 and the groove 1061 are aligned, the second return spring pushes the connecting rod 125 to move toward the first storage barrel 107, and the impact block 126 hits the first storage barrel 107, causing the first storage barrel 107 to vibrate, thereby ensuring that the bearing in the first storage barrel 107 falls normally and avoiding the situation where the bearing is stuck in the first storage barrel 107.
