Description

Technical Field

[0001] The utility model relates to the field of bearing processing, and more specifically, to a bearing ring polishing machine for bearing processing. Background Art

[0002] Bearings are common standard parts in industrial production, mainly providing support for transmission shafts and reducing friction. Existing bearings are mainly divided into rolling bearings and sliding bearings, among which rolling bearings are mainly composed of inner and outer rings and rolling elements. Therefore, during the production of bearings, the surface of the bearing ring needs to be polished to ensure the stability of the bearing during installation. Existing bearing ring polishing machines mainly perform surface polishing through relative rotation with the grinding wheel. At the same time, in order to improve production efficiency, the bearing will be moved axially, and then multiple bearing rings will be polished continuously. This makes the polishing marks on the surface of the bearing ring spiral during the polishing process, which will cause greater friction in the bearing during the subsequent use of the bearing, affecting the bearing life. At the same time, the bearing will rotate when it is rubbed by the grinding wheel. If the bearing ring is not limited enough or too tight, the relative speed difference between the bearing ring and the grinding wheel will change, affecting the consistency of bearing polishing.

[0022] Example:

[0023] See also Figure 1 , Figure 2 and Figure 4As shown, a bearing ring polishing machine for bearing processing comprises a workbench 1, the surface of the workbench 1 is symmetrically provided with slide grooves 2, a moving block 3 is slidably installed on the upper surface of the workbench 1, a connecting frame 10 is arranged at the bottom of the moving block 3, the connecting frame 10 passes through the slide grooves 2 on both sides, a threaded rod 23 is transversely installed inside the workbench 1 through a bearing, the threaded rod 23 is parallel to the slide groove 2, the connecting frame 10 is screwed on the threaded rod 23, the moving block 3 can be driven to move through the threaded rod 23, and then the distance between the emery roller 5 and the mounting shaft 11 is controlled to realize the grinding and polishing work, an extension plate 4 is symmetrically arranged on one side of the moving block 3, an emery roller 5 is vertically installed between the two extension plates 4 through a bearing, the emery roller 5 exceeds the end surface of the extension plate 4 to ensure that when the emery roller 5 contacts the bearing ring, the upper and lower extension plates 4 will not cause obstruction, an installation shaft 11 is vertically installed on one side of the upper surface of the workbench 1 through a bearing, the installation shaft 11 can rotate to ensure that the active speeds of multiple bearing rings are consistent, and the axes of the installation shaft 11 and the emery roller 5 are parallel.

[0024] Please refer to Figure 2 and Figure 4 As shown, the surface of the mounting shaft 11 is symmetrically provided with mounting grooves 12, and extrusion strips 13 are slidably installed inside the two mounting grooves 12. The extrusion strips 13 extend beyond the outer surface of the mounting shaft 11, and a rubber strip 14 is glued to the outer surface of the extrusion strip 13. The rubber strip 14 can protect the inner wall of the bearing ring, thereby ensuring a high clamping force while preventing the inner part of the bearing ring from being damaged. A lateral adjustment screw 22 is laterally screwed on one side of the workbench 1 close to the mounting shaft 11, and a ball is arranged at the end of the lateral adjustment screw 22, which contacts the outer surface of the mounting shaft 11. Rotating the lateral adjustment screw 22 can extrude the mounting shaft 11, thereby increasing or reducing the friction between the two, thereby creating a speed difference between the sand roller 5 and the mounting shaft 11, thereby achieving grinding and polishing.

[0025] Among them, a bottom hole 19 is opened at the lower part of the installation shaft 11, and a slide bar 18 is vertically slidable at the center of the installation shaft 11. The bottom of the slide bar 18 is placed inside the bottom hole 19, and a spring 20 is arranged inside the bottom hole 19. The top of the spring 20 contacts the lower surface of the slide bar 18. The elastic force of the spring 20 makes the slide bar 18 always have an upward force, and then the top of the slide bar 18 always contacts the surface of the longitudinal control bolt 21. The slide bar 18 is evenly installed with a connecting rod 17 through a pin shaft. The end of the connecting rod 17 away from the slide bar 18 is installed on the inner wall of the extrusion strip 13 through a pin shaft. The connection direction of the connecting rod 17 is to ensure that the extrusion strips 13 on both sides can be pulled inward when the slide bar 18 moves up, so as to facilitate the installation or removal of the bearing ring. A longitudinal control bolt 21 is screwed on the top of the installation shaft 11, and the lower surface of the longitudinal control bolt 21 contacts the upper surface of the slide bar 18.

[0026] Please refer to Figure 1 and Figure 3As shown, a driven pulley 6 is provided on the top of the sand roller 5, and the driven pulley 6 is placed above the extension plate 4. A motor 7 is fixed to the surface of the moving block 3 on the side facing away from the sand roller 5. A driving pulley 8 is installed upward at the output end of the motor 7. Belts 9 are provided on the surfaces of the driven pulley 6 and the driving pulley 8 to provide power to the sand roller 5.

[0027] Please refer to Figure 1 and Figure 4 As shown, an extension edge 16 is provided on the surface of the mounting shaft 11 to ensure that the mounting shaft 11 can rotate while improving its stability. The extension edge 16 is placed on the upper surface of the workbench 1, and the limiting bolts 15 are symmetrically screwed on the surface of the mounting shaft 11. The limiting bolts 15 are placed above the extension edge 16 to support the bottom of the bearing ring. The length of the limiting bolts 15 can be adjusted according to the thickness of different bearing rings.

[0028] Working principle: Due to the existence of the spring 20, the slide bar 18 always has an upward elastic force, so that the top of the slide bar 18 is tightly attached to the bottom of the longitudinal control bolt 21. When the longitudinal control bolt 21 is screwed up, the slide bar 18 will move up, and then the extrusion strips 13 on both sides will be retracted through the connecting rod 17, and then the distance between the two extrusion strips 13 will be reduced to facilitate the installation of the bearing ring. The bearing rings to be polished are placed one by one on the surface of the installation shaft 11, and the limit bolt 15 is screwed in, so that the limit bolt 15 supports the lowest bearing ring and ensures that the end face of the limit bolt 15 does not exceed the outer circle of the bearing ring. Then, the longitudinal control bolt 21 is screwed down to tighten the slide bar 18. The support is carried out so that the extrusion bar 13 moves outward and then clamps the bearing ring, and then the threaded rod 23 is rotated to drive the moving block 3 to move as a whole, so that the sand roller 5 contacts the outer circles of multiple bearing rings, and the motor 7 is started to drive the sand roller 5 to rotate at a high degree by driving the belt 9, so as to realize polishing and grinding of multiple bearing rings at the same time. When the sand roller 5 contacts the bearing ring, it will drive the bearing ring and the mounting shaft 11 to rotate as a whole. At this time, the friction force on the surface of the mounting shaft 11 can be squeezed by screwing the transverse adjustment screw 22 to reduce the rotation speed of the mounting shaft 11, so that the bearing ring forms a speed difference with the sand roller 5 while rotating, thereby improving the grinding efficiency.

[0029] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
