[0030] Embodiment 1:

[0031] This embodiment provides a grinding device, which can be applied to a grinding machine for grinding bearings. Referring to Figures 1 - 5 , it includes a mounting base 1, a grinding mechanism 2, and a driving mechanism 3. The grinding mechanism 2 is mounted on the mounting base 1. The grinding mechanism 2 includes at least two grinding assemblies 21. Different grinding heads are respectively mounted on the multiple grinding assemblies 21, and the grinding assemblies 21 are all movably connected to the mounting base 1. The driving mechanism 3 is arranged on the mounting base 1 and is used to drive the grinding assemblies 21 to rotate relative to the mounting base 1, changing the positions of the grinding assemblies 21 on the mounting base 1. When the grinding assemblies 21 rotate, their positions relative to the workpiece to be ground also change accordingly, so that one of the multiple grinding assemblies 21 can be switched to the processing position. During grinding, according to the actual processing requirements, the grinding assembly 21 equipped with a grinding head that meets the processing requirements can be rotated to the processing position, thereby realizing the grinding of different parts of the bearing.

[0032] Furthermore, the drive mechanism 3 and the grinding mechanism 2 are connected via a connecting disc 4, which is rotatably mounted on the mounting base 1. Multiple grinding assemblies 21 are connected to the connecting disc 4. Driven by the drive mechanism 3, the connecting disc 4 rotates, driving the grinding assemblies 21 to rotate relative to the mounting base 1, thereby changing the positions of the grinding assemblies 21. Furthermore, the grinding assemblies 21 are evenly spaced along the circumference of the connecting disc 4. This not only ensures that the multiple grinding assemblies 21 can be rotated to the processing positions in sequence, but also optimizes the layout of the multiple grinding assemblies 21 on the connecting disc 4, improving the aesthetics while preventing interference between the grinding assemblies 21.

[0033] In this embodiment, in order to facilitate the replacement and maintenance of the grinding assembly 21 , the grinding assembly 21 can be detachably connected to the connecting plate 4 .

[0034] Reference Figure 3 In this embodiment, the driving mechanism 3 includes a worm wheel 33 and a worm 32 that are in transmission cooperation, and a motor 31 for driving the worm 32 to rotate. The worm 32 is engaged with the worm wheel 33, and the connecting disk 4 is fixed on the worm wheel 33. Both the worm wheel 33 and the worm 32 can be rotatably installed in the mounting seat 1. The mounting seat 1 has an accommodating space for installing the worm wheel 33 and the worm 32. When the driving mechanism 3 is working, the motor 31 drives the worm 32 to rotate, and the worm 32 drives the worm wheel 33 to rotate, thereby driving the connecting disk 4 connected to the worm wheel 33 to rotate, thereby realizing the position change of multiple grinding components 21 installed on the connecting disk 4.

[0035] In this embodiment, a circular groove 11 is provided on the mounting seat 1, and the central axis of the circular groove 11 coincides with the rotation axis of the connecting disk 4, and a locking component 5 is provided between the mounting seat 1 and the connecting disk 4. One end of the locking component 5 is slidably connected in the circular groove 11, and the other end is connected to the connecting disk 4, that is, when the connecting disk 4 rotates, it can drive the locking component 5 to slide in the circular groove 11. The provision of the circular groove 11 can provide a guiding effect for the rotation of the connecting disk 4, thereby ensuring the accuracy of the rotation of the connecting disk 4 on the mounting seat 1.

[0036] Furthermore, the locking component 5 is provided with an outward-protruding snap-fitting portion 51 at one end close to the mounting seat 1, and the inner edge of the circular groove 11 is provided with an outward-protruding blocking portion 12 extending along the circular groove 11. When the locking component 5 slides in the circular groove 11, the blocking portion 12 can interfere with the snap-fitting portion 51 to prevent the locking component 5 from disengaging from the circular groove 11, thereby ensuring that the connecting disk 4 can always be connected to the mounting seat 1, thereby improving the connection stability between the mounting seat 1 and the connecting disk 4.

[0037] Further, a plurality of locking members 5 are provided and arranged at intervals in the circumferential direction of the connecting plate 4. The plurality of locking members 5 can disperse the stress received by the connecting plate 4 during the grinding process.

[0038] In this embodiment, positioning holes corresponding to the locking members 5 are provided on the connecting plate 4. The locking members 5 are inserted through the positioning holes and plugged on the connecting plate 4. Refer to Figure 5 , the locking member 5 is a locking oil cylinder. A pressing member 52 capable of abutting and closely fitting with the surface of the connecting plate 4 is provided at the movable end of the locking oil cylinder. When the locking oil cylinder works, it can drive the pressing member 52 to be in close contact with or separated from the surface of the connecting plate 4. When the pressing member 52 is in close contact with the surface of the connecting plate 4, the locking oil cylinder provides a locking force, and the connecting plate 4 is locked on the mounting seat 1, which can prevent the connecting plate 4 from loosening or displacing during the grinding process and ensure the stability of the grinding assembly 21 during grinding. When the pressing member 52 is separated from the connecting plate 4, the locking member 5 will not interfere with the rotation of the connecting plate 4 on the mounting plate.
