The support rod is fixed inside the movable installation groove, and the bottom of the support rod is erected by the support plate at the bottom of the connecting sleeve 6; the positioning rod 8 is movably installed on the outside of the connecting rod 7 through the rotating shaft, and the connection point is located at the end of the connecting rod 7 close to the bottom The middle section of the positioning rod 8 is also provided with a rotating shaft to facilitate the folding and expansion of the positioning rod 8, and the bottom end of the positioning rod 8 is a sharp corner; the connecting ring 9 is sleeved on the outer surface of the connecting rod 7, and the bottom of the connecting ring 9 is connected to the top end of the positioning rod 8 through a movable shaft, the top of the connecting ring 9 is a gasket, and a reset spring is installed above the gasket. The support plate at the bottom of the connecting sleeve 6 is above the reset spring. The electric telescopic rod 4 pushes the connecting sleeve 6 to move toward the full ball bearing 3, and the connecting sleeve 6 drives the connecting rod 7 when it moves. The movement of the connecting rod 7 drives the positioning rod 8. After the electric telescopic rod 4 is extended to a certain length, the positioning rod 8 When the bottom falls on the upper surface of the full ball bearing 3, the connecting rod 7 keeps its position, and the electric telescopic rod 4 continues to push the connecting sleeve 6 downward. Since the top of the connecting rod 7 is sleeved inside the connecting sleeve 6, the connecting sleeve 6 has a certain range of motion. When the connecting sleeve 6 continues to move downward, the support plate at the bottom of the connecting sleeve 6 pushes the spring above the connecting ring 9 to press the connecting ring 9 downward. When the connecting ring 9 moves down along the connecting rod 7, the positioning rod 8 is opened and folded. After the positioning rod 8 is folded, the middle connection position of the positioning rod 8 is opened to expand outward, and the two sleeved inner and outer rings are propped open by the expanded positioning rod 8 to facilitate the subsequent installation and rotation of the balls.

[0028] The outer surface of the connecting sleeve 6 is sleeved with a sleeve ring 2 10, and a motor 11 is installed on one side of the top plate 2 corresponding to the transmission chain 1. The transmission end of the motor 11 is connected to the sleeve ring 2 10 through a support rod. The motor 11 corresponds to the center of the full ball bearing 3. The motor 11 drives the connecting sleeve 6 to rotate. The connecting sleeve 6 drives the electric telescopic rod 1 4 and the connecting rod 7. When the connecting rod 7 moves above the full ball bearing 3, the bottom end of the positioning rod 8 is inserted into the gap between the inner and outer rings of the full ball bearing 3. Due to the reset spring on the top of the connecting ring 9, the positioning rod 8 remains in the expanded state after sliding into the gap between the inner and outer rings of the full ball bearing 3. When the outer wall of the positioning rod 8 slides When it reaches the installation groove opened at the top of the full ball bearing 3, the positioning rod 8 is stuck in the installation groove, so that the stuck inner and outer rings rotate together with the connecting rod 7, so that the installation grooves opened on the inner and outer rings of the full ball bearing 3 are aligned with each other. After the installation grooves of the inner and outer rings of the full ball bearing 3 are aligned, it is convenient for the subsequent balls to enter the full ball bearing 3 from the installation grooves of the full ball bearing 3. When the motor 11 drives the connecting sleeve 6 to rotate one circle through the ring 10, the mounting hole of the full ball bearing 3 is positioned to the specified position, and the connecting rod 7 is moved up by the electric telescopic rod 4 to make the positioning rod 8 disengage from the interior of the full ball bearing 3, and the positioned full ball bearing 3 is driven by the transmission chain 1 to move to the subsequent assembly tooling.

[0029] A guide tube 12 is installed at the bottom of the top plate 2. The bottom of the guide tube 12 is located above the full ball bearing 3, and the opening at the bottom of the guide tube 12 corresponds to the installation groove position of the full ball bearing 3. One end of a ball tube 13 is fixed to one side of the guide tube 12. The guide tube 12 and the ball tube 13 are connected to each other. The balls enter the inside of the guide tube 12 through the ball tube 13, and the opening at the bottom of the guide tube 12 corresponds to the installation groove position at the top of the full ball bearing 3, so that the balls can enter the inside of the full ball bearing 3 conveniently. An electric telescopic rod 14 is installed above the guide tube 12, and the telescopic end of the electric telescopic rod 14 is located inside the guide tube 12. A pressure block 15 is fixed to the telescopic end of the electric telescopic rod 14, and the distance between the pressure block 15 and the full ball bearing 3 is controlled by the electric telescopic rod 14. When the ball inside the guide tube 12 falls into the installation groove of the full ball bearing 3, since the ball diameter is slightly larger than the installation groove diameter of the full ball bearing 3, the ball cannot directly enter the full ball bearing 3 smoothly. At this time, the pressure block 15 can be pushed down by the electric telescopic rod 14, so that the pressure block 15 pushes the ball into the full ball bearing 3. The pressure block 15 can be made of elastic rubber to reduce the damage to the surface of the ball when it is pushed.

[0030] Working principle: the inner and outer rings of the full ball bearing 3 are assembled, and one side of the installation groove of the full ball bearing 3 is facing upwards, and the assembled full ball bearing 3 is placed on the surface of the transmission chain 1 for transmission. When the full ball bearing 3 moves to the bottom of the electric telescopic rod 4, the transmission chain 1 stops moving, and the electric telescopic rod 4 pushes the connecting sleeve 6 to descend, and the connecting sleeve 6 drives the connecting rod 7 and the positioning rod 8 to move downward, so that the bottom of the positioning rod 8 is inserted between the inner and outer rings of the full ball bearing 3, and as the connecting sleeve 6 continues to move downward, the outer wall of the positioning rod 8 is stuck in the full ball bearing 3 and begins to fold from the middle, thereby expanding the diameter. After the electric telescopic rod 4 is extended and retracted a certain distance, it stops moving and the motor 11 is started. The motor 11 drives the connecting sleeve 6 to rotate through the sleeve ring 10. When the connecting sleeve 6 rotates, it drives the connecting rod 7 and the positioning rod 8. The positioning rod 8 rotates on the surface of the full ball bearing 3. When the side wall of the positioning rod 8 encounters the installation groove of the full ball bearing 3, the positioning rod 8 is retracted through the top of the connecting ring 9. After the cam 12 is released, the cam 13 is released, and the cam 14 is released, so that the cam 13 is in a state of being moved and disengaged from the inner and outer rings of the full ball bearing 3.
