After the ring is clamped, the motor is started, and the motor drives the connecting rod to rotate through the rotating disk. During the rotation of the rotating disk, the arc block is driven to rotate through the sliding base. The ring is ground by the rotation of the grinding blocks connected to the outer surfaces of the two sets of arc blocks, thereby reducing the processing time and operation steps and improving production efficiency.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the above-mentioned device supports the inner ring of the grinding ring to grind the outer ring of the ferrule, lacks the function of grinding the inner and outer rings at the same time, and needs to arrange the processes of processing the inner and outer rings separately, which increases the complexity of production and is not conducive to efficient processing. The overall idea is as follows: it includes a device body 11, the lower end of the device body 11 is fixedly connected to a motor 12, the outer surface of the motor 12 is sleeved with a rotating disk 13, the rotating disk 13 is rotatably connected to the inside of the device body 11, the upper end of the rotating disk 13 is fixedly connected to a connecting rod 14, the outer surface of the connecting rod 14 is sleeved with two first gears 15, the two first gears 15 are provided with a slide groove 16, the rotating disk 13 is rotatably connected to the inside, and the adjustment mechanism includes two rotating Rod 17, the two rotating rods 17 are rotatably connected inside the rotating disk 13, the outer surfaces of the two rotating disks 13 are sleeved with second gears 18, the two second gears 18 are respectively meshed with the two first gears 15, and the inside of the device body 11 is slidably connected with two groups of sliding bases 19, the two groups of sliding bases 19 are respectively sleeved inside the two groups of slide grooves 16, and the upper ends of the two groups of sliding bases 19 are fixedly connected with arc blocks 21, and the two rotating rods 17 can be screwed respectively. The rotating rod 17 drives the two second gears 18 to rotate, and the first gear 15 is driven to rotate through the meshing of the second gear 18. During the rotation of the first gear 15, the sliding base 19 is driven to slide through the slide groove 16 to adjust the placement position of the arc block 21 to adapt to rings of different sizes, thereby realizing flexible production and improving applicability.

[0027] The outer surfaces of the two groups of arc blocks 21 are both sleeved with grinding blocks 22. After the ring is clamped, the motor 12 is started. The motor 12 drives the connecting rod 14 to rotate through the rotating disk 13. During the rotation of the rotating disk 13, the arc block 21 is driven to rotate through the sliding base 19. The ring is ground by the rotation of the grinding blocks 22 sleeved on the outer surfaces of the two groups of arc blocks 21, which reduces the processing time and operation steps and improves production efficiency.

[0028] A circular ring 23 is slidably connected to the outer surface of the device body 11, and a cylinder 24 is fixedly connected to the lower end of the circular ring 23. A clamping block 25 is rotatably connected inside the circular ring 23. A limiting block 26 is fixedly connected to the outer surface of the limiting block 26. The clamping block 25 is slidably connected to the outer surface of the limiting block 26. The hemispherical hydrodynamic bearing ring that needs to be ground is placed on the device body 11, and the cylinder 24 is started. The cylinder 24 pushes the circular ring 23 downward to slide. During the sliding process of the circular ring 23, the clamping block 25 is driven to press down and clamp the part to ensure the stability of the placement of the ring during grinding. After the processing is completed, the cylinder 24 drives the clamping block 25 to slide upward. During the sliding process of the clamping block 25, it is squeezed outward by the limiting block 26 to rotate, thereby increasing the picking space to facilitate the picking and unloading of materials.

[0029] In view of the problems existing in the prior art, the utility model provides a hemispherical hydrodynamic bearing part grinding tool. After the ring is clamped, the motor 12 is started. The motor 12 drives the connecting rod 14 to rotate through the rotating disk 13. During the rotation of the rotating disk 13, the sliding base 19 drives the arc block 21 to rotate. The grinding block 22 connected to the outer surface of the two groups of arc blocks 21 rotates to grind the ring, thereby reducing the processing time and operation steps and improving production efficiency.

[0030] Working principle:

[0031] The first step is to place the hemispherical hydrodynamic bearing ring that needs to be ground on the device body 11, start the cylinder 24, and the cylinder 24 pushes the ring 23 downward to slide. During the sliding process of the ring 23, the clamping block 25 is driven to press down and clamp the part to ensure the stability of the ring placement during grinding. After the processing is completed, the cylinder 24 drives the clamping block 25 to slide upward. During the sliding process of the clamping block 25, it is squeezed outward and rotated by the limit block 26 to increase the picking space, so as to achieve the purpose of facilitating the picking and unloading.

[0032] In the second step, after the ring is clamped, the motor 12 is started. The motor 12 drives the connecting rod 14 to rotate through the rotating disk 13. During the rotation of the rotating disk 13, the arc block 21 is driven to rotate through the sliding base 19. The ring is ground by rotating the grinding blocks 22 connected to the outer shells of the two groups of arc blocks 21, thereby reducing the processing time and operation steps and improving the production efficiency. Before the grinding process, the two rotating rods 17 can be screwed separately. The rotating rods 17 drive the two second gears 18 to rotate, and the first gear 15 is driven to rotate through the meshing of the second gears 18. During the rotation of the first gear 15, the sliding base 19 is driven to slide through the slide groove 16 to adjust the placement of the arc block 21 to adapt to rings of different sizes, thereby realizing flexible production and improving applicability.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
