[0006] A rolling element assembly mechanism for assembling a retainer and a tapered roller into a rolling element;

[0007] An inner flange conveying mechanism for conveying an inner flange;

[0008] A final assembly mechanism for completing the assembly of the inner flange and the rolling element;

[0009] Wherein, the conveying direction of the rolling element assembly mechanism is the first conveying direction and the first conveying direction is linearly arranged; the rolling element assembly mechanism comprises a horizontal moving assembly, and the horizontal moving assembly comprises:

[0010] A first station for placing a retainer;

[0011] A second station for placing a tapered roller on the retainer;

[0012] A third station for detecting a rolling element;

[0014] A horizontal feeding component, so that the workpiece passes through the second station and the third station in sequence from the first station to the fourth station;

[0015] Wherein, the horizontal feeding component is provided with a pressing member, and the pressing member is used to press the tapered roller on the retainer.

[0016] By adopting the above technical solution, the horizontal feeding component transports the cage at the first station to the second station for inserting the tapered rollers. Then, the cage containing the tapered rollers is transferred to the third station for inspection. Next, the qualified cage containing the tapered rollers is transferred to the fourth station. During the transfer to the fourth station, the clamping component on the horizontal feeding component presses the tapered rollers onto the cage to form a complete rolling element. Then, at the fourth station, the inner flange conveyed by the inner flange conveying mechanism is assembled with the rolling element at the fourth station by the general assembly mechanism. During this process, no manual intervention is required, and the assembly is completed automatically, resulting in high production efficiency. At the same time, the clamping component is located on the horizontal feeding component, and the assembly is completed simultaneously during the workpiece transfer process, which can reduce the length of the entire production line.

[0017] Optionally, the horizontal feeding component includes a feeding actuator and an actuator translation component; the actuator translation component is used to drive the feeding actuator to reciprocate along the vertical direction of the first conveying direction; the feeding actuator includes three sets of jaws, jaw opening and closing components, and a feeding drive component; the feeding drive component is used to drive the three sets of jaws and jaw opening and closing components to reciprocate along the first conveying direction; the three sets of jaws are distributed along the first conveying direction and correspond to three adjacent workstations in sequence; the jaw opening and closing components are used to synchronously drive the three sets of jaws to close or open to grip and release workpieces; the feeding drive component and the actuator translation component cooperate to realize the reciprocating movement of the three sets of jaws along a "U"-shaped path; the clamping component is located at the set of jaws near the end of the first conveying direction.

[0018] By adopting the above technical solution, the three sets of gripper components are first located at the first, second, and third workstations, respectively.

The actuator, translation component, and feeding drive component drive the three sets of gripper components and the three workpieces on them to move back and forth along a "U"-shaped path. That is, first, they move outward away from the workstation, then move horizontally with a movement distance equal to the center distance between two workstations, and then return inward to the workstation. In this way, the workpieces reach the next workstation for the next process. The clamping component is located at the set of gripper components near the end of the first conveying direction. It can clamp the rolling elements during the process of gripping the cage containing the tapered rollers and transporting it to the fourth workstation.
