[0002] Ball bearings are composed of inner and outer rings, balls, and upper and lower cages. These parts will be assembled uniformly after production. The last step of the assembly process is to use an assembly machine to rivet and press the upper and lower cages. Existing assembly machines are generally composed of a machine body, a drive cylinder, an upper press part, and a lower press part.

[0003] Existing application number: CN201220157128.5, a bearing cage assembly machine, including a workbench and a support frame vertically arranged on the workbench, a lower die is arranged on the workbench, an upper die installed on the support frame is arranged above the lower die, an upper annular protrusion that can be inserted into the connection between the bearing and the cage ball pocket is arranged at the lower end of the upper die, and a lower annular protrusion that can be inserted into the connection between the bearing and the cage ball pocket is arranged at the upper end of the lower die, and a vertical cylinder is arranged on the support frame, and the lower end of the piston rod of the cylinder is fixed with the upper die, and the cylinder is connected to an air source reversing solenoid valve through an air pipe, and the air source reversing solenoid valve is connected to the air source, and the air source reversing solenoid valve is controlled by a start switch.

[0060] Sliding rod 701, sliding rod 701 is fixedly connected to the bottom right end of connecting rod 7, and sliding rod 701 is slidably connected inside transmission box 301 and workbench main body 1, so that when driving cylinder 2 drives its piston rod to move downward, it will drive sliding rod 701 to slide downward inside transmission box 301 and workbench main body 1 through connecting rod 7.

[0061] The rotation components also include:

[0062] A transmission rack 702, the transmission rack 702 is fixedly connected below the sliding rod 701;

[0063] The transmission gear 8 is rotatably connected inside the transmission box 301, and the transmission gear 8 is meshed with the transmission rack 702. The effect brought about is that when the connecting rod 7 slides downward, the transmission gear 8 will be driven to rotate through the gear rack transmission mechanism formed by the meshing of the transmission gear 8 and the transmission rack 702.

[0064] The rotation components also include:

[0065] A transmission ratchet 801, which is coaxially fixedly connected to the left side of the transmission gear 8;

[0071] The specific usage and function of this embodiment are as follows:

[0072] The bearings with the upper and lower retainers are placed on the multiple lower pressing parts 6, and then the driving cylinder 2 is started. The driving cylinder 2 drives its piston rod to move downward, and drives the sliding rod 701 to slide downward inside the transmission box 301 and the workbench body 1 through the connecting rod 7. When the connecting rod 7 slides downward, it drives the transmission gear 8 to rotate through the gear rack transmission mechanism formed by the meshing of the transmission gear 8 and the transmission rack 702.

After the multiple bearings on the multiple lower pressing parts 6 are pressed and installed, the staff can remove the multiple bearings together.

[0073] Embodiment 2:

[0074] Based on the first embodiment, as shown in the attached Figure 1 To Attachment Figure 6 As shown, a lifting assembly is also included. The lifting assembly is provided in multiple groups, and the multiple groups of lifting assemblies are dispersedly arranged inside the rotating table 5.

[0078] The lifting ring 13 is slidably connected inside the installation groove 11, and the lifting ring 13 is fixedly connected to the top of the multi-piece connecting spring 12. The effect is that the multi-piece connecting spring 12 lifts the lifting ring 13 and the bearing placed on the lifting ring 13. When the upper press-fitting part 201 moves downward to cooperate with the lower press-fitting part 6 to press and rivet the retaining frame inside the bearing, the lifting ring 13 is driven to move downward. When the upper press-fitting part 201 rises, under the action of the multi-piece connecting spring 12, the lifting ring 13 moves upward, and the bearing is lifted up at the same time, which makes it convenient for the staff to take out the bearing.

[0079] The specific usage and function of this embodiment are as follows:

[0080] The multi-piece connecting spring 12 lifts up the lifting ring 13 and the bearing placed on the lifting ring 13. When the upper press-fitting part 201 moves downward to cooperate with the lower press-fitting part 6 to press and rivet the retaining frame inside the bearing, the lifting ring 13 is driven to move downward. When the upper press-fitting part 201 rises, under the action of the multi-piece connecting spring 12, the lifting ring 13 moves upward back to its original position, and the bearing is lifted up at the same time, avoiding the molecular-level interaction force between the lower surface of the bearing and the rotating table 5 when the bearing is squeezed, resulting in viscosity between the two, which makes it more laborious to pick up the bearing. The staff can pick up the bearing more easily.
