[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a fine grinding machine with the following advantages:

[0020] 1. This utility model, by setting a fine grinding head, allows for the rotation of a bidirectional screw via a drive component when processing bearings of different specifications. This causes the bidirectional screw to drive two support blocks to move relative to or in opposite directions, thereby adjusting the distance between the two grinding blocks and bringing them into contact with the inner wall of the bearing. Then, a servo motor can be started to drive the connecting block to rotate, which in turn drives the grinding block to rotate via the support block. The grinding block then polishes the inner wall of the bearing, making it suitable for processing bearings of different specifications and improving fine grinding efficiency.

[0028] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0029] This utility model provides a technical solution:

[0030] Please see Figures 1-3 A precision grinding machine includes a servo motor 1 and a precision grinding head 2. The precision grinding head 2 is fixedly installed at the output end of the servo motor 1. The precision grinding head 2 includes a connecting block 21 fixedly connected to the output end of the servo motor 1. Support blocks 22 are slidably connected to both sides of the connecting block 21. A detachable grinding block 23 is fixedly installed at the end of the support block 22. A bidirectional screw 24 is rotatably installed inside the connecting block 21. The two support blocks 22 are respectively sleeved on both ends of the bidirectional screw 24 and threadedly connected to the bidirectional screw 24. A driving component 25 is provided in the middle of the bidirectional screw 24. By setting the precision grinding head 2, when processing bearings of different specifications, the bidirectional screw 24 can be rotated by the drive component 25, causing the bidirectional screw 24 to drive the two support blocks 22 to move relative to or in opposite directions. This allows the spacing between the two grinding blocks 23 to be adjusted so that the grinding blocks 23 contact the inner wall of the bearing. Then, the servo motor 1 can be started to drive the connecting block 21 to rotate, causing the connecting block 21 to drive the grinding blocks 23 to rotate through the support blocks 22. The grinding blocks 23 then grind the inner wall of the bearing, making it convenient for processing bearings of different specifications and improving precision grinding efficiency.

[0031] Specifically, the driving component 25 includes a worm 251 rotatably mounted in the connecting block 21 and a worm wheel 252 fixedly connected to the bidirectional screw 24. The worm 251 meshes with the worm wheel 252. By setting the driving component 25, the worm 251 can be rotated during adjustment, causing the worm 251 to drive the worm wheel 252 to rotate, which in turn drives the bidirectional screw 24 to rotate.

[0032] Furthermore, a first groove 26 is provided on one side of the fine grinding head 2, and the end of the worm 251 is located in the first groove 26. By providing the first groove 26, the worm 251 can be prevented from being hit.

[0033] Furthermore, limit grooves 27 are provided on both the upper and lower sides of the support block 22, and limit blocks 28 are provided on both sides of the connecting block 21. The limit blocks 28 are slidably connected to the limit grooves 27. By setting the limit grooves 27 and the limit blocks 28, the support block 22 can be limited, thereby improving the stability of the support block 22 and preventing the support block 22 from detaching from the connecting block 21.

[0034] Furthermore, a scale bar 29 is provided on the side wall of the support block 22. By setting the scale bar 29, when adjusting the grinding block 23, the spacing of the grinding block 23 can be judged by observing the scale corresponding to the scale bar 29, thereby improving the adjustment accuracy of the grinding block 23.

[0035] Reference Figure 2 and Figure 3 The support block 22 has an installation groove 210 at its end. The grinding block 23 is fixedly connected to one side of the mounting block 211. The mounting block 211 is fixedly installed in the mounting groove 210 by bolts 212. The mounting block 211 has a threaded hole 213 inside that matches the bolts 212. By setting the mounting groove 210, the mounting block 211 and the bolts 212, when the grinding block 23 is worn out after long-term use, the bolts 212 can be loosened to remove the grinding block 23 from the support block 22 and the grinding block 23 can be replaced.

[0036] Furthermore, a second groove 214 is provided on the top surface of the support block 22, and the end of the bolt 212 is located in the second groove 214. By providing the second groove 214, the bolt 212 can be prevented from being hit.

[0037] In practical use, the working principle of this utility model is as follows:

[0038] First, when processing bearings of different specifications, the worm 251 can be rotated, causing the worm 251 to drive the worm wheel 252 to rotate, which in turn drives the bidirectional screw 24 to rotate. This causes the bidirectional screw 24 to drive the two support blocks 22 to move relative to or in opposite directions, thereby adjusting the distance between the two grinding blocks 23 so that the grinding blocks 23 come into contact with the inner wall of the bearing.

[0039] Then, the servo motor 1 can be started to drive the connecting block 21 to rotate, so that the connecting block 21 drives the grinding block 23 to rotate through the support block 22. The grinding block 23 grinds the inner wall of the bearing, thus making it convenient to process bearings of different specifications.

[0040] To improve the adjustment accuracy of the grinding block 23, a scale bar 29 is provided. When adjusting the grinding block 23, the spacing of the grinding block 23 can be judged by observing the scale corresponding to the scale bar 29.

[0041] When the grinding block 23 is severely worn after long-term use, the bolt 212 can be loosened to remove the grinding block 23 from the support block 22, and the grinding block 23 can be replaced.

[0042] In summary, by setting up a fine grinding head 2, this fine grinding machine can adjust the distance between two grinding blocks 23 when processing bearings of different specifications. The grinding blocks 23 grind the inner wall of the bearing, thus making it suitable for processing bearings of different specifications and improving fine grinding efficiency.

[0043] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
