Description

Technical Field

[0001] This application relates to the field of flat ball bearing assembly, and more particularly to a shock absorber flat ball bearing assembly machine. Background Technology

[0002] Shock absorber ball bearings are important components commonly used in mechanical equipment, and their performance directly affects the vibration damping effect and service life. Shock absorber ball bearings typically consist of a cage and multiple steel balls. During assembly, the steel balls must be precisely embedded into the sockets of the cage, ensuring the fit between the steel balls and the cage is accurate.

[0003] Traditional flat-face ball bearing assembly relies primarily on manual operation. Workers manually place the steel balls one by one into the sockets of the cage, and then complete the assembly using simple tools or by hand. However, manually placing the steel balls one by one is time-consuming and difficult to meet the needs of mass production. Repetitive manual operations can easily lead to worker fatigue and increase the assembly error rate. Summary of the Invention

[0035] The upper end of the lower mold 3 is used to place the retainer, and the positioning post 41 is used to position the retainer. After the retainer is correctly positioned, the positioning post 41 slides down away from the annular groove 31 to prevent interference with the installation of the steel ball. The annular groove 31 is used for the steel ball to be embedded.

[0036] Reference Figure 1 The ball loading assembly 2 is used to place steel balls on the cage. The upper mold 1 is located above the lower mold 3.

The movable component 23 includes a second cylinder and a third cylinder. The cylinder body of the second cylinder is fixedly connected to the mounting platform such as a wall, and the piston rod of the second cylinder is fixedly connected to the cylinder body of the third cylinder. The piston rod of the third cylinder is fixedly connected to the mounting platform 21. The second cylinder is used to control the horizontal sliding of the third cylinder, and the third cylinder is used to control the vertical sliding of the mounting platform 21.

[0040] The ball-blocking plate 24 is located directly above the lower ball positioning plate 22. The spring 25 is located on the outer periphery of the lower ball positioning plate 22. One end of the spring 25 is fixedly connected to the mounting platform 21, and the other end of the spring 25 is fixedly connected to the ball-blocking plate 24. The upper end of the ball-blocking plate 24 is provided with a placement groove 241. Multiple springs 25 are provided, and the multiple springs 25 are evenly spaced around the axis of the placement groove 241. The driving cylinder controls the ball-blocking plate 24 to slide up and down.

[0041] Reference Figure 4 The bottom of the placement trough 241 is coaxially provided with a ball drop opening 242, which vertically penetrates the ball-blocking plate 24. The height of the bottom of the placement trough 241 increases as it moves away from the ball drop opening 242. The motor housing of the servo motor 26 is connected to the mounting platform 21 via a bracket, and the motor shaft of the servo motor 26 is coaxially fixedly connected to the ball loading plate 27.

[0042] The ball loading tray 27 is used to be embedded in the placement groove 241. When the ball loading tray 27 is embedded in the placement groove 241, the upper end face of the ball loading tray 27 is flush with the upper end face of the ball blocking tray 24. The ball loading tray 27 is provided with a ball loading port 271, which penetrates the ball loading tray 27 vertically. There are multiple ball loading ports 271, which are evenly spaced along the axis of the placement groove 241.

[0044] The implementation principle of the shock absorber flat ball bearing assembly machine in this application embodiment is as follows: the cage positioning plate 4 slides upward, causing the positioning pin 41 to slide out of the positioning port 32. The positioning pin 41 positions the cage for installation, so that the hole of the cage for installing steel balls is aligned with the annular groove 31. After the cage is installed, the cage positioning plate 4 slides downward, causing the positioning pin 41 to move away from the annular groove 31. The first cylinder 29 pushes the hose 28 to move, so that the hose 28 moves above the ball loading plate 27. The servo motor 26 controls the ball loading plate 27 to rotate, so that the steel balls automatically fall into the ball loading port 271 and are placed in the slot 24. The bottom of the groove 1 limits the steel ball, preventing it from detaching from the ball loading tray 27; the moving part 23 controls the mounting platform 21 to move directly above the lower mold 3, the ball blocking plate 24 slides downward, and the bottom of the placement groove 241 can no longer block the movement of the steel ball. The steel ball falls from the ball loading tray 27 into the larger diameter collection port 2211, and enters the discharge port 2212 along the collection port 2211. Each steel ball falls into the hole of the retainer; the moving part 23 controls the mounting platform 21 to move away from the lower mold 3, and the upper mold 1 slides downward to press the steel ball, completing the assembly with the retainer. After installation, the upper mold 1 is reset; the operation is repeated.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
