[0028] Please refer to Figures 1-4 This utility model proposes a high-speed bearing processing equipment, including a frame and a rotating platform disposed within the frame. The rotating platform is provided with a plurality of limiters evenly distributed along the rotation axis of the rotating platform. The outer circumferential direction of the rotating platform is provided with an inner ring feeding mechanism, an outer ring feeding mechanism, a ball assembly mechanism and an oil injection mechanism.

[0029] In the technical solution of this utility model, high-speed bearings are processed by a multi-station rotary platform. The rotary platform can quickly and accurately rotate the workpiece to different stations for processing. By clamping it once with a limiter, the accuracy is higher when installing and loading at different stations in the subsequent stages, avoiding errors caused by multiple positioning. At the same time, it saves production space and costs, and allows for parallel operation. Multi-station processing allows multiple workpieces to be processed at different stations at the same time.

[0030] In another embodiment of this utility model, a tilting unloading device is also included. The tilting unloading device includes a tilting plate and a tilting plate linear actuator. The limiter is disposed on the tilting plate. The tilting plate is hinged to the rotating platform. The tilting plate linear actuator is used to drive the tilting plate to rotate.

[0031] In another embodiment of the present invention, the limiter includes an inner ring fixing post and an outer ring limiting block, wherein the outer ring limiting block is disposed outside the inner ring fixing post.

[0032] Specifically, it is equipped with an inner ring fixing post and an outer ring limiting block to fix the inner and outer rings respectively, so that the positioning is more precise and they do not interfere with each other.

[0033] In another embodiment of the present invention, the limiter further includes a plurality of limit posts, which are disposed outside the inner ring fixing posts and are evenly distributed circumferentially along the axis of the inner ring fixing posts. The limit posts are used to limit the balls.

[0034] Specifically, the limiting post is used to limit the ball bearings.

[0035] More specifically, the limiting post is disposed on the limiting ring, and the limiting ring and the limiting post are detachably connected to accommodate different ball gaps.

[0036] In another embodiment of the present invention, the limiter further includes an outer ring linear actuator and an outer ring slide rail. The outer ring limiting block is slidably disposed on the outer ring slide rail. The outer ring linear actuator drives the outer ring limiting block to slide on the outer ring slide rail to move closer to or further away from the inner ring positioning post.

[0037] Specifically, the outer ring limit block is slidably set through the outer ring linear actuator and the outer ring slide rail, thus adapting to different outer ring diameters.

[0038] In another embodiment of this utility model, the limiter further includes an inner ring linear actuator, an inner ring guide rail, and an inner ring plate. The inner ring fixing post is fixed on the inner ring plate. A through hole is provided on the rotating platform. The inner ring plate is disposed in the through hole. The inner ring plate is slidably disposed on the inner ring guide rail. The inner ring guide rail is disposed on the rotating platform. The inner ring linear actuator drives the inner ring plate to slide on the inner ring guide rail to move closer to or further away from the through hole in the vertical direction.

[0039] Specifically, the inner ring linear actuator drives the inner ring plate to slide on the inner ring slide rail to move closer to or further away from the through hole in the vertical direction, thereby removing the inner ring fixing post, which is suitable for subsequent operation of other equipment, and at the same time, it can prevent contamination of the inner ring fixing post during the oil injection operation.

[0040] In another embodiment of this utility model, the inner ring fixing post is configured as a stepped shaft, and the diameter of the fixing post gradually decreases from near the inner ring plate to far away from it.

[0041] Specifically, the inner ring fixing post is configured as a stepped shaft, which, together with the inner ring linear actuator, drives the inner ring plate to be limited to different stepped positions on the stepped shaft, thereby adapting to different inner ring diameters.

[0042] In another embodiment of this utility model, the inner ring slide rail is inclinedly and fixedly connected to the rotating platform. When the inner ring linear actuator drives the inner ring plate to slide on the inner ring slide rail, it moves closer to or away from the through hole in both the vertical and horizontal directions. The limiter also includes an outer ring linear actuator and an outer ring slide rail. The outer ring limit block is slidably disposed on the outer ring slide rail. The outer ring linear actuator drives the outer ring limit block to slide on the outer ring slide rail to move closer to or away from the inner ring positioning post.

[0043] Specifically, the inner ring slide rail is tilted and fixedly connected to the rotating platform. When the inner ring linear actuator drives the inner ring plate to slide on the inner ring slide rail, it moves closer to or further away from the through hole in both the vertical and horizontal directions. As a result, when the outer ring linear actuator drives the outer ring limiting block to slide away from the inner ring positioning post on the outer ring slide rail, the bearing is no longer limited, causing the bearing to fall off.

[0044] More specifically, a bearing conveying station is provided on the outer side of the rotating platform, and a bearing conveyor belt is provided at the bearing conveying station. A bearing conveyor belt is also provided below the through hole.

[0045] In another embodiment of this utility model, a cover plate assembly mechanism is also provided on the outer side of the rotating platform.

[0046] Specifically, after the inner ring linear actuator drives the inner ring plate away, the space freed up can be used for cover plate assembly.

[0047] In another embodiment of this utility model, the inner ring feeding mechanism includes a base plate, an inner ring baffle, an inner ring baffle linear actuator, a side plate, and an inner ring conveyor belt parallel to the side plate. The distance between the inner ring conveyor belt and the side plate is less than the diameter of the inner ring. The inner ring baffle is disposed between the side plate and the inner ring conveyor belt. The baffle linear actuator is used to drive the baffle.

[0048] Specifically, the inner ring is secured by the side plate and the inner ring conveyor belt parallel to the side plate and moved to the top of the inner ring fixing post. Then, the inner ring baffle linear actuator drives the inner ring baffle to move the inner ring and fit it onto the outside of the inner ring fixing post, thereby making the positioning more accurate and avoiding collision between the side of the inner ring and the inner ring fixing post.

[0049] In another embodiment of this utility model, an inner ring hole is provided on the base plate, the inner ring hole is located below the inner ring baffle, the diameter of the inner ring hole is larger than the diameter of the inner ring, and a base plate baffle is provided on the base plate, the base plate baffle is located at the conveying end of the base plate.

[0050] Specifically, the inner ring is positioned by using the base plate baffle, ensuring that the inner ring is above the inner ring fixing post, resulting in more precise positioning.

[0051] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
