Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly, and particularly relates to a device for individually discharging bearing cages. Background Art

[0002] A bearing is a commonly used mechanical component. A bearing is assembled from components such as an outer ring, an inner ring, balls, and a bearing cage. Among them, the bearing cage plays a role of equally spacing the rolling elements (balls) in a rolling bearing, preventing the rolling elements from falling off, and guiding and driving the rolling elements to rotate.

[0003] Existing bearing cages are usually assembled by two cage components. When assembling the cage, the cage components are stored in a feeding mechanism. Since the bearing cages are assembled one by one in the mechanized assembly process, it is also required that the feeding device can discharge the cage components one by one, and the discharging rhythm needs to be synchronized with the assembly line.

[0004] Therefore, there is an urgent need to provide a discharging device with a reliable structure that can control the individual discharging of cage components to meet the assembly requirements of bearing cages. Summary of the Invention

[0005] The purpose of the utility model is to provide a discharging device with a reliable structure that can control the individual discharging of cage components to meet the assembly requirements of bearing cages.

[0006] The purpose of the utility model is realized by the following technical solutions: A device for individually discharging bearing cages includes a base plate, a guide rod, and a material distributing mechanism. The cage component is sleeved on the guide rod. The material distributing mechanism includes an upper component, a lower component, and a rotating ring arranged between the upper component and the lower component. There is a slider between the lower component and the rotating ring. One end of the slider close to the center of the rotating ring is provided with a material distributing head. A driving member for driving the rotating ring to rotate is arranged on the base plate. When the rotating ring rotates, it drives the material distributing head to move along the radial direction of the rotating ring;

[0007] Central holes are provided on both the upper component and the lower component. The lower end of the guide rod extends into the central holes on the upper component and the lower component.

[0008] In the present utility model, the cage assembly is controlled by the material distributing mechanism to be discharged one by one, and the material distributing mechanism switches between an open state and a closed state; when the material distributing mechanism is in the open state, the material distributing head on the material distributing mechanism moves along the radial outer side of the rotating ring to the outer extreme limit position, and at this time, the cage assembly sleeved on the guide rod can pass through the central hole; when the material distributing mechanism is in the closed state, the material distributing head on the material distributing mechanism moves along the radial inner side of the rotating ring to the inner extreme limit position, and at this time, the cage assembly located above the material distributing head will be blocked by the material distributing head, and the cage assembly located above the material distributing head will not be able to pass through the central hole. When discharging the cage assembly one by one, the material distributing mechanism first switches from the closed state to the open state. At this time, the cage assembly sleeved on the guide rod and located at the lowermost end will fall through the central hole and be discharged, and then quickly switches from the open state to the closed state. The material distributing head will block the cage assembly above the lowermost cage assembly to prevent the cage assembly above from continuing to fall; through the above method, the cage assembly can be discharged one by one, thus meeting the assembly requirements of the bearing cage, and the structure of the present utility model is reliable and not prone to failure during the working process.

[0026] A slider 15 is provided between the lower component 5 and the rotating ring 8. One end of the slider 15 close to the center of the rotating ring 8 is provided with a material distribution head 16, and the material distribution head 16 is wedge-shaped. Central holes are provided on both the upper component 4 and the lower component 5, and the lower end of the guide rod 2 extends into the central holes on the upper component 4 and the lower component 5.

[0027] Among them, the lower component 5 is circular. A chute 17 is provided on the lower component 5. The chute 17 is arranged along the radial direction of the lower component 5. The slider 15 is slidably connected in the chute 17. In this embodiment, three chutes 17 are uniformly arranged on the lower component 5. A sliding pin 19 is provided on the slider 15, and a guiding inclined groove 21 corresponding to the sliding pin 19 is provided on the rotating ring 8. The sliding pin 19 extends into the guiding inclined groove 21. The included angle between the guiding inclined groove 21 and the tangent of the rotating ring 8 is 30 to 45 degrees.

[0028] A driving member 3 for driving the rotation of the rotating ring 8 is provided on the substrate 1. Specifically, a connecting arm 6 is provided on the rotating ring 8, and a connecting hole 7 is provided on the connecting arm 6. The connecting hole 7 is an elongated hole. The driving member 3 is a cylinder. The front end of the piston rod of the cylinder is provided with a connecting shaft 9, and the connecting shaft 9 extends into the connecting hole 7 on the connecting arm 6.
