[0002] Bearing raceways and shaft components with radius (R) are typically profiled using circular arc grinding wheels. The workpiece's geometry depends almost entirely on the shape of the circular arc grinding wheel, thus profiled grinding places extremely high demands on the accuracy of the circular arc grinding wheel's shape.

[0003] Grinding wheels need to be dressed and sharpened before use. Dressing gives the grinding wheel a certain geometric shape, while sharpening makes it sharp. Currently, there are two common dressing methods for grinding wheels: one is cut-in forming dressing, and the other is CNC interpolation forming dressing. For the former, a rotating frame with an arc shape is usually set up, and a hard diamond pen is placed at the geometric center of the rotating frame. By reciprocating the rotation of the rotating frame and moving the hard diamond pen horizontally, the outer side of the workpiece can be processed using a feed method, thus realizing the production of the grinding wheel. In the existing technology, the above processing is mostly done manually by controlling the rotation and movement of the rotating frame. This manual control not only increases the labor intensity but also affects the processing accuracy due to human factors. In addition, when adapting the workpiece processing position to the equipment's location, the existing equipment has certain limitations and cannot meet the needs of production and processing.

The reciprocating rotation component of the trimming component 9 can drive the hard diamond pen 92 to move in a reciprocating oscillating manner in the horizontal direction, so that the hard diamond pen 92 can act on the outer periphery of the workpiece, ensuring the smooth progress of the processing work. At the same time, the reciprocating rotation of the hard diamond pen 92 can improve the functionality of the device. In addition, the rotation drive component 10 can drive the trimming component 9 to rotate and adjust, thereby realizing convenient adjustment of the position of the trimming component 9 to ensure different production and processing processes, greatly improving the functionality of the device. In the above process: the established transverse sliding component 3 and longitudinal sliding component 5 facilitate the positioning of the device in the transverse and longitudinal directions, ensuring the smooth progress of subsequent processing. The established dressing component 9, in which the reciprocating rotation component drives the hard diamond pen 92 to move in a reciprocating oscillating manner in the horizontal direction, allowing the hard diamond pen 92 to act on the outer periphery of the workpiece, ensuring the smooth progress of processing. At the same time, the reciprocating rotation of the hard diamond pen 92 can improve the functionality of the device. In addition, the established rotation drive component 10 can drive the dressing component 9 to rotate and adjust, thereby realizing convenient adjustment of the position of the dressing component 9 to ensure different production and processing processes, greatly improving the functionality of the device. This device is reasonably designed, simple in structure, easy to process, and can replace manual labor to complete the processing and operation of the dressing component 9. On the one hand, it can reduce the labor intensity of people and ensure the smooth progress of production and processing. On the other hand, it can ensure the production and processing accuracy of the workpiece, guarantee the forming quality of the workpiece, and improve the functionality of the device, effectively meeting the needs of use.

[0015] To further improve the rationality of the device setup, the transverse sliding assembly 3 includes a transverse slide bar 31, with a transverse slider 32 positioned above the transverse slide bar 31. A transverse drive cylinder 33 is located on one side of the frame 1, controlling the operation of the transverse drive cylinder 33. Its output end can drive the transverse plate 4 to move and adjust laterally, thereby facilitating the positioning of the trimming assembly 9 and ensuring that the trimming assembly 9 is in different processing positions to adapt to different workpieces. Furthermore, the longitudinal sliding assembly 5 includes a longitudinal slide bar 51 positioned above the transverse plate 4, with a longitudinal slider 52 positioned above the longitudinal slide bar 51. A rodless cylinder 53 is positioned between the two longitudinal slide bars 51, and its output end is connected to the longitudinal plate 6. The longitudinal sliding assembly 5 allows for convenient adjustment of the longitudinal plate 6 in the longitudinal direction. The rodless cylinder 53 provides driving power and acts on the longitudinal plate 6, adjusting the longitudinal position of the longitudinal plate 6 and the trimming assembly 9 placed on it to meet different usage requirements, greatly improving the practicality of the device.

[0016] To ensure the continuous processing, the dressing assembly 9 includes an arc-shaped adjusting plate 91 housed within the rotating plate 8. The adjusting plate 91 is rotatably connected to the rotating plate 8. A hard diamond pen 92 is housed within the adjusting plate 91, rotating with it and acting on the outer side of the workpiece to complete the dressing. A reciprocating rotating assembly is located above the rotating plate 8. During operation, this assembly drives the adjusting plate 91 to reciprocate relative to the rotating plate 8, allowing the hard diamond pen 92 to move during processing. Smooth feeding can be achieved. Specifically, the reciprocating rotary assembly includes a concave frame 93 positioned above and on the outer side of the rotating plate 8, providing a convenient installation location. A rotating gear 94 is positioned above the adjusting plate 91, and a sector tooth 95 is positioned on one side of the rotating gear 94 and connected to the concave frame 93. A rotating rod 96 is positioned inside the concave frame 93, corresponding to the rotation mode of the adjusting plate 91. A connecting plate 97 is positioned below the rotating rod 96, and a drive rod 98 is positioned below the connecting plate 97. A key plate 99 is positioned above the sector tooth 95. The sector tooth 95 and the key plate 99 are connected by a rod and can rotate synchronously. The key plate 99 has a key groove 991 that matches the drive rod 98. Specifically, the rotating rod 96 receives external driving power, and its rotation drives the connecting plate 97 and the drive rod 98 to rotate together. The drive rod 98 is placed in the key groove 991. The rotation of the connecting plate 97 allows the drive rod 98 to rotate axially around the rotating rod 96, and, constrained by the key groove 991, the key plate 99 can reciprocate. The sector teeth 95 rotate along with it, and the rotation of the sector teeth 95 meshes with the rotating gear 94. The reciprocating rotation of the former then acts on the rotating gear 94, driving the rotating rod 96 to reciprocate. In this way, the adjusting plate 91 connected to the rotating rod 96 also performs a reciprocating oscillating operation. The hard diamond pen 92 is close to the outside of the workpiece and performs a reciprocating dressing action under the drive of the adjusting plate 91. This greatly improves the functionality of the device, has a high degree of automation, reduces the labor intensity of people, and meets the needs of users.

[0017] To facilitate the adjustment of the trimming assembly 9 at different processing positions to meet various processing needs, the rotation drive assembly 10 includes a rotating shaft 101 housed within a support frame 7 and connected to a rotating plate 8. The upper end of the rotating shaft 101 extends through the support frame 7. A mounting plate 102 is positioned above the support frame 7. A longitudinal drive cylinder 103 is positioned above one side of the mounting plate 102, and a limiting slide 104 is positioned below one side of the mounting plate 102. A longitudinal shift rack 105 is housed within the limiting slide 104, and one end of the rack is connected to the output end of the longitudinal drive cylinder 103. It should be further noted that the output end of the longitudinal drive cylinder 103 is connected to the geometric center of the longitudinal shift rack 105. In other words, when in a stationary state, i.e., when the rotating plate 8 is perpendicular to the support plate, the extension length of the longitudinal drive cylinder 103 is half of its extension. Thus, when its extension is controlled to continue, the rotating plate 8 can be... When rotating counterclockwise, the rotating plate 8 can also rotate clockwise when retracted. The rotation process continues until it is parallel to the support plate, which is the maximum movement position. Of course, during the rotation process, its position can be adjusted according to different usage requirements. A driven gear 106 is provided above the rotating shaft 101 and meshes with the longitudinal rack 105. A protective cover 107 with a concave design is provided on the support frame 7 located outside the driven gear 106. In other words, the protective cover 107 is provided to protect the inner equipment and prevent damage to the equipment components. In use, by controlling the extension or retraction of the longitudinal drive cylinder 103, it will drive the longitudinal rack 105 to move and mesh with the driven gear 106, thereby driving the rotating shaft 101 to rotate together with the driven gear 106. The position of the rotating plate 8 can be adjusted to meet different processing requirements.
