[0002] Bearing dust covers are important seals used in bearings to prevent dust and impurities from entering the bearing and to ensure the normal operation of the bearing. Usually, after the bearing is finished, it is placed aside and cannot be used immediately. At this time, bearing dust covers are needed for protection. However, most bearing dust covers are currently made by stamping. Due to the plastic deformation of the material during the processing, burrs and rough edges are easily generated on the edges of the dust cover.

[0003] In the existing technology, a simple threaded rod drives a clamping device to hold the dust cover. Since the inner and outer rings of the dust cover are circular, and without a limit, it is very easy to lift up during clamping, which affects the repair of burrs. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] Please see Figures 1 to 6 This utility model provides a technical solution: a burr cleaning device for processing bearing dust covers, including a workbench 1, a base 2 located on the workbench 1, and a mounting seat 3 fixed on the upper surface of the base 2 for placing the dust cover. The surface of the mounting seat 3 is provided with a through groove 4 and a material leakage structure. The material leakage structure includes a central groove 7 and an inclined groove 8, which are connected. The central groove 7 is located on the middle surface of the mounting seat 3. There are three sets of inclined grooves 8, which extend outward through the side of the mounting seat 3. The three sets of inclined grooves 8 are distributed around the central circumference of the mounting seat 3. Each set of inclined grooves 8 is located between two sets of through grooves 4. There are three sets of through grooves 4, which are distributed around the central circumference of the mounting seat 3.

[0023] Specifically, the burr removal device consists of a cleaning chamber, a conveying or positioning mechanism, a rotating or vibrating cleaning assembly, and a chip removal system. The workpiece is first positioned and pressed onto a support platform by the positioning mechanism. The platform typically has a through-slot structure and adjustable clamping blocks. The clamping blocks are moved via threads or guide rails to ensure they are tightly against the workpiece edge, achieving initial fixation. Subsequently, the cleaning assembly, such as a high-speed rotating grinding head, moves relative to the workpiece edge along a set trajectory to remove burrs generated by stamping, cutting, or impact. During the cleaning process, the detached chips or burrs fall into the central collection chamber of the support platform under gravity or centrifugal force, and are guided to the outer chip removal outlet via inclined grooves or guide channels within the platform for automatic discharge, preventing impurities from accumulating or interfering with the positioning of the next workpiece.

The top plate of the movable retaining seat 6 is located above the mounting base 3, and the bottom plate of the movable retaining seat 6 is located inside the through groove 4. A pre-limiting structure is fixed on the movable retaining seat 6. The pre-limiting structure includes an arc-shaped protrusion 9, an arc-shaped protrusion 10, a limiting protrusion 11, and a threaded rod 12. The arc-shaped protrusion 9 is fixed to the upper surface of the movable retaining seat 6, and the arc-shaped protrusion 9 is located near the mounting base. At one end of the center of 3, the side of the arc-shaped protrusion 9 away from the center of the mounting base 3 is arc-shaped. The arc-shaped protrusion 10 is screwed by the threaded rod 12. The top surface of the arc-shaped protrusion 10 is flush with the top surface of the arc-shaped protrusion 9. The arc-shaped protrusion 10 is located outside the arc-shaped protrusion 9. The side of the arc-shaped protrusion 10 close to the center of the mounting base 3 is arc-shaped. The limiting protrusion 11 is fixed at the top of the arc-shaped protrusion 9 and the arc-shaped protrusion 10. The limiting protrusion 11 is used to limit the dust cover.

[0027] To reiterate, when placing the bearing dust cover, leave the area that needs to be trimmed exposed so that it is not blocked by the limiting protrusion 11. After the other surfaces are repaired, loosen the clamp, rotate the blocked edge until it is exposed, then fix it with the clamp again, and finally grind it with the grinding head.

[0028] In use, the bearing dust cover is placed on the movable bracket 6. According to the size of the bearing dust cover, the threaded rod 15 is rotated to move the movable bracket 6, and the threaded rod 212 is rotated to move the arc-shaped protrusion 210. The arc-shaped protrusion 19 and the arc-shaped protrusion 210 are arranged to lock the inner and outer rings of the dust cover. The limiting protrusions 11 on the arc-shaped protrusion 19 and the arc-shaped protrusion 210 limit the dust cover to prevent it from being squeezed and lifting up when the dust cover is clamped. At the same time, when cleaning the edge of the dust cover, the impurities that fall on the mounting base 3 can be cleaned and leak out from the inclined groove 8.
