For example, bearings are used in various machinery and conveying equipment, such as rollers, gears and reducers. For example, in vehicles, bearings are mostly used in wheels, engines, gearboxes and suspension mechanisms to reduce friction and support rotation and movement.

[0003] During the production process of the bearing, the side wall of the inner ring needs to be punched to facilitate the installation of the ball, and the lubricant can enter the bearing raceway and rolling element through the hole as lubricant, thereby lubricating the bearing and improving the service life and operating efficiency of the bearing.

The sliding cylinder 31 is fixedly connected to the translation stage 2, the sliding plate 3 is slidably connected to the translation stage 2, and the sliding plate 3 and the output shaft of the sliding cylinder 31 are fixedly connected. When it is necessary to drive the bearing ring to move in the vertical direction, the sliding cylinder 31 is started to make the output shaft of the sliding cylinder 31 move up and down, and drive the bearing ring to move up and down.

[0035] like Figure 3 and Figure 4 As shown, the internal support mechanism includes a support cylinder 4, a first connecting block 41, a connecting rod 42, a connecting sleeve 43, a second connecting block 44, a reinforcing rod 45 and a support block 46.

[0036] When it is necessary to drill a hole in the bearing ring, the bearing ring needs to be clamped and positioned, and the supporting cylinder 4 is started.

At this time, the connecting rod 42 located on the first connecting block 41 moves toward the position of the bearing ring under the drive of the supporting cylinder 4, and the connecting sleeve 43 is fixedly connected to the supporting cylinder 4. The reinforcing rod 45 and the connecting rod 42 move toward the outer wall close to the connecting sleeve 43, so that the supporting block 46 moves toward the outer wall close to the connecting sleeve 43, and at this time, the sliding cylinder 31 is started, so that the output shaft of the sliding cylinder 31 drives the sliding plate 3 to move, so that the output shaft of the supporting cylinder 4 abuts against the bottom of the position where the bearing ring is located, and the output shaft of the supporting cylinder 4 is recovered, driving the first connecting block 41 to move toward the supporting cylinder 4, so that the supporting block 46 moves toward the inner wall of the bearing ring, and when the abutting block 47 on the supporting block 46 abuts against the inner sides of the two annular surfaces of the bearing ring, the inner diameter side wall of the bearing ring is supported.

When the abutment platform 52 moves toward the bottom wall of the bearing ring, the pressing rod 54 is moved under the drive of the abutment platform 52, and during the movement, the pressing block 55 is pushed to move toward the top wall of the bearing ring, so that the pressing block 55 abuts against the top wall of the bearing ring, and the abutment platform 52 abuts against the bottom wall of the bearing ring, so that the position of the bearing ring is adjusted.

[0040] When the drilling is completed, the output shaft of the pressing cylinder 51 drives the abutment platform 52 to move toward the side away from the bearing ring, causing the abutment platform 52 to descend. When the abutment platform 52 descends, the pressing block 55 moves toward the side away from the top wall of the bearing ring under the push of the return spring 58, thereby releasing the clamping of the bearing ring.

[0043] The output shaft of the sliding cylinder 31 drives the sliding plate 3 to move upward. After the sliding plate 3 moves upward, the translation motor 21 is started. The output shaft of the translation motor 21 drives the translation rod 22 to rotate, so that the translation rod 22 drives the translation platform 2 to move horizontally along the translation rod 22. When the bearing ring moves to the drilling platform 5, the sliding cylinder 31 is started, so that the sliding cylinder 31 drives the bearing ring to move onto the drilling platform 5.

[0044] Start the pressing cylinder 51, so that the output shaft of the pressing cylinder 51 moves toward the position of the bearing ring, and the abutment platform 52 moves toward the bottom wall of the bearing ring under the drive of the pressing cylinder 51. When the abutment platform 52 moves toward the bottom wall of the bearing ring, the pressing rod 54 moves under the drive of the abutment platform 52, and pushes the pressing block 55 to move toward the top wall of the bearing ring during the movement, so that the pressing block 55 abuts against the top wall of the bearing ring, and the abutment platform 52 abuts against the bottom wall of the bearing ring. The position of the bearing ring is adjusted so that the position of the bearing ring where the hole needs to be drilled and the drill rod 73 are in the same horizontal plane, and the output shaft of the pressing cylinder 51 drives the abutment platform 52 to move toward the side away from the bearing ring, so that the abutment platform 52 descends, and the pressing block 55 moves toward the side away from the top wall of the bearing ring under the drive of the return spring 58, thereby releasing the clamping of the bearing ring.

After drilling a single position, the sliding table 71 drives the drilling motor 72 to reset, and starts the rotating motor 6, so that the rotating motor 6 drives the bearing ring to move to the next drilling position, and repeats the above process to achieve drilling of the bearing ring.

[0047] In this embodiment, when drilling a hole in the bearing ring, the bearing ring can be pressed by pressing block 55, so as to reduce the local deviation of the bearing ring and improve the position accuracy of the hole. By pressing the bearing ring, the position of the hole can be ensured to be more precise, the drilling position error caused by the deviation of the bearing ring can be reduced, and it helps to maintain the roundness and size consistency of the hole.

[0048] In this embodiment, the labor intensity of the workers is reduced by driving the bearing ring to move in the horizontal direction and the vertical direction, and the position accuracy of the bearing ring when entering the drilling platform 5 can be enhanced to a certain extent.

[0049] In this embodiment, by driving the bearing ring to rotate, the probability of the bearing ring needing manual adjustment when drilling a hole in the bearing ring can be reduced, and by rotating the bearing ring, the position of each hole on the bearing ring can be made more precise, thereby ensuring the accuracy of the hole position and eliminating the need for frequent stopping mechanisms to reposition the bearing ring, thereby reducing downtime and improving the continuous operation capability of the production line.

[0050] In this embodiment, by supporting the inner wall of the bearing ring, the bearing ring can be prevented from being deformed due to cutting force during the drilling process, and the shape and dimensional accuracy of the bearing ring can be maintained.
