Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a bearing outer ring processing device. Background Technology

[0002] During the bearing manufacturing process, the outer ring of the bearing is usually ground to ensure a smooth finish after assembly.

[0003] A search revealed Chinese Patent CN217890520U, which discloses a bearing outer ring processing device. The device includes a base, on which a pneumatic chuck is vertically mounted. Above the chuck's jaws is a grinding mechanism that can be vertically raised and lowered. The grinding mechanism includes a housing, within which a turntable is housed. The turntable has evenly protruding locking blocks along its edge, and corresponding locking grooves within the housing. Several grinding rods of different roughnesses are evenly arranged on the turntable. The number of locking blocks matches the number of grinding rods, which are located on the same circumference. A rotating platform is rotatably mounted within the housing, and a spring is fixed to the platform, with the other end of the spring fixedly connected to the turntable. The advantages are: by rotating the turntable to switch between grinding rods of different roughnesses, the bearing outer ring can be ground from coarse to fine without disassembly, reducing operation steps and improving processing efficiency.

[0004] In the aforementioned existing technical solution, the bearing outer ring is ground from coarse to fine by rotating a turntable to switch between grinding rods of different roughness. The switching process does not require disassembly, reducing operation steps and improving processing efficiency. However, in actual use, both the inner and outer side walls of the bearing outer ring need to be ground. The aforementioned existing technical solution only uses one grinding rod to grind the side wall of the bearing outer ring at a time, so only one side wall of the bearing outer ring can be ground, resulting in low grinding efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a bearing outer ring processing device. The bearing outer ring to be processed is placed on the top of the positioning plate. The sliding block is moved by the compression spring, so that the side wall of the grinding rod is in contact with the inner and outer side walls of the bearing outer ring. The positioning plate is rotated by the drive component, and the bearing outer ring rotates with the positioning plate. The grinding rod grinds the inner and outer side walls of the bearing outer ring, thereby improving the processing efficiency of the bearing outer ring.

[0006] The technical solution to achieve the purpose of this utility model is: a bearing outer ring processing device, including a base, a positioning plate is provided on the top of the base, a drive component is provided inside the base, a support frame is fixedly installed on the side wall of the base, a hydraulic rod is fixedly installed on the top wall of the support frame, and a grinding component is fixedly installed at the output end of the hydraulic rod. The grinding component includes:

[0007] A movable disk, which is fixedly mounted on the bottom wall of the hydraulic rod;

[0008] The sliding groove has multiple sliding grooves, which are equidistantly formed on the side wall of the movable disk. The inner side wall of the sliding groove has a limit groove, and two sliding blocks are slidably installed inside the limit groove.

[0009] The grinding rods are in multiple quantities, with two grinding rods forming a group. The multiple grinding rods slide through the interior of the sliding block. Two compression springs are fixedly connected to the inner sidewall of each sliding groove. The ends of the two compression springs that are close to each other are fixedly connected to the sidewall of the adjacent sliding block. A positioning component is provided at the bottom of the moving disk.

[0010] In some embodiments, the driving component includes;

[0011] The drive motor and the snap-fit ​​block are fixedly mounted on the inner bottom wall of the base, and the snap-fit ​​block is fixedly mounted on the output shaft of the drive motor and snaps into the inside of the positioning plate.

[0012] In some embodiments, the positioning component includes;

[0013] The positioning cone and the rotating rod are provided. The positioning cone is cone-shaped, and the rotating rod is fixedly installed on the top wall of the positioning cone. The top end of the rotating rod is rotatably installed at the center of the inside of the moving disk.

[0014] In some embodiments, the sidewall of the positioning cone is provided with multiple receiving grooves, which are respectively aligned with multiple sliding grooves.

[0015] In some embodiments, the grinding rods can only slide up and down inside the sliding block, and the roughness of the sidewalls of each set of grinding rods is different.

[0016] Compared with the prior art, the significant advantages of this utility model are:

[0017] Firstly, this invention places the outer ring of the bearing to be processed on top of a positioning plate. Two grinding rods inside the sliding groove are moved to opposite sides, positioning them on the inner and outer sides of the outer ring. The output of a hydraulic rod moves the moving plate downwards, bringing the positioning assembly into contact with the inner wall of the outer ring, thus positioning the outer ring. A compression spring pushes the sliding block to move, bringing the sidewalls of the grinding rods into contact with the inner and outer walls of the outer ring. A drive assembly rotates the positioning plate, causing the outer ring to rotate with it, and the grinding rods polish the inner and outer walls of the outer ring, improving the processing efficiency. By moving the moving plate with the hydraulic rod and adjusting the grinding rods, multiple sets of grinding rods sequentially polish the sidewalls of the outer ring. This solves the problem that existing bearing outer ring processing devices can only polish one side of the outer ring.

[0018] Secondly, this utility model uses a conical positioning cone so that when the positioning cone moves downward with the moving disk, the side wall of the positioning cone can fit against the inner side wall of the outer ring of the bearing. The positioning cone is rotatably installed inside the rotating rod, so that the positioning cone can rotate synchronously with the drive assembly, which facilitates the rotation of the outer ring of the bearing. The receiving groove facilitates the movement of the grinding rod inside the positioning cone. Attached Figure Description

[0027] This utility model provides an improved bearing outer ring machining device. The technical solution of this utility model is as follows:

[0028] like Figures 1-4 As shown, a bearing outer ring machining device includes a base 1, a positioning disk 2 on the top of the base 1, and a drive assembly inside the base 1. The drive assembly includes a drive motor 3 and a locking block 4. The drive motor 3 is fixedly installed on the inner bottom wall of the base 1, and the locking block 4 is fixedly installed on the output shaft of the drive motor 3 and is locked inside the positioning disk 2. A support frame 5 is fixedly installed on the side wall of the base 1, and a hydraulic rod 6 is fixedly installed on the top wall of the support frame 5. A grinding assembly is fixedly installed at the output end of the hydraulic rod 6. The grinding assembly includes a moving disk 7, sliding grooves 8, and grinding rods 11. The moving disk 7 is fixedly installed on the bottom wall of the hydraulic rod 6. There are multiple sliding grooves 8, which are equidistantly spaced on the side wall of the moving disk 7. A limit groove 9 is formed on the inner side wall of the sliding groove 8. Two sliding blocks 10 are slidably installed inside the limit groove 9. There are multiple grinding rods 11, which are grouped in pairs. The multiple grinding rods 11 slide through the interior of the sliding blocks 10. The grinding rods 11 can only slide up and down inside the sliding blocks 10. Each group... The grinding rods 11 have different roughness on their sidewalls. Two compression springs 12 are fixedly connected to the inner sidewall of each sliding groove 8. The ends of the two compression springs 12 that are close to each other are fixedly connected to the sidewall of the adjacent sliding block 10. A positioning assembly is provided at the bottom of the moving disk 7. The bearing outer ring to be processed is placed on the top of the positioning disk 2. The two grinding rods 11 inside the sliding groove 8 are moved to opposite sides, so that the two grinding rods 11 inside the sliding groove 8 are located on the inner and outer sides of the bearing outer ring, respectively. The movement is achieved through the output end of the hydraulic rod 6. The disk 7 moves downward, causing the positioning component to fit against the inner wall of the bearing outer ring, thus positioning the bearing outer ring. The sliding block 10 is moved by the compression spring 12, causing the side wall of the grinding rod 11 to fit against the inner and outer walls of the bearing outer ring. The positioning disk 2 is rotated by the drive component, and the bearing outer ring rotates together with the positioning disk 2. The grinding rod 11 grinds the inner and outer walls of the bearing outer ring. By moving the moving disk 7 with the hydraulic rod 6, the grinding rod 11 grinding the bearing outer ring is adjusted, so that multiple sets of grinding rods 11 grind the side wall of the bearing outer ring in sequence.

[0029] like Figures 1-4As shown, in this embodiment, the positioning component includes a positioning cone 13 and a rotating rod 14. The positioning cone 13 is cone-shaped, and the rotating rod 14 is fixedly installed on the top wall of the positioning cone 13. The top end of the rotating rod 14 is rotatably installed at the center of the moving disk 7. The side wall of the positioning cone 13 is provided with multiple receiving grooves 15, which are respectively aligned with multiple sliding grooves 8. Through the cone-shaped positioning cone 13, when the positioning cone 13 moves downward with the moving disk 7, the side wall of the positioning cone 13 can fit against the inner side wall of the outer ring of the bearing. The positioning cone 13 is rotatably installed inside the rotating rod 14, so that the positioning cone 13 can rotate synchronously with the drive component, which facilitates the rotation of the outer ring of the bearing. The receiving grooves 15 facilitate the movement of the grinding rod 11 inside the positioning cone 13.

[0030] The specific working method is as follows: Place the outer ring of the bearing to be processed on the top of the positioning disk 2. Move the two grinding rods 11 inside the sliding groove 8 to the opposite side, so that the two grinding rods 11 inside the sliding groove 8 are located on the inner and outer sides of the outer ring of the bearing, respectively. Move the moving disk 7 downward through the output end of the hydraulic rod 6, so that the positioning component is in contact with the inner side wall of the outer ring of the bearing, thereby positioning the outer ring of the bearing. Push the sliding block 10 to move through the compression spring 12, so that the side wall of the grinding rod 11 is in contact with the inner and outer side walls of the outer ring of the bearing. Drive the positioning disk 2 to rotate through the drive component, and the outer ring of the bearing rotates together with the positioning disk 2. The grinding rod 11 grinds the inner and outer walls of the bearing outer ring. By moving the moving disk 7 with the hydraulic rod 6, the grinding rod 11 grinding the bearing outer ring is adjusted so that multiple sets of grinding rods 11 grind the side wall of the bearing outer ring in sequence. Through the conical positioning cone 13, when the positioning cone 13 moves downward with the moving disk 7, the side wall of the positioning cone 13 can fit against the inner side wall of the bearing outer ring. The positioning cone 13 is rotatably installed inside the rotating rod 14 so that the positioning cone 13 can rotate synchronously with the drive assembly, which facilitates the rotation of the bearing outer ring. The receiving groove 15 facilitates the movement of the grinding rod 11 inside the positioning cone 13.
