[0037] Example 1:

[0038] like Figures 1 to 7 As shown, this embodiment provides a large disc drive surface calibration tool, including a telescopic component 2, a first measuring gauge 1, and a positioning component 3. Positioning components 3 are provided at both opposite ends of the telescopic component 2. The first measuring gauge 1 is fixed to the telescopic component 2, with its measuring end located inside and below the positioning end of the positioning component 3. The telescopic component 2 allows for calibration of large discs of different sizes. The positioning component 3 is pressed against the inner ring of the large disc and abuts against the mounting surface of the diamond-shaped seat. Rotating the tool causes the measuring gauge to rotate, with its bottom abutting against the drive surface used to mount the steel balls. The measuring gauge rotates circumferentially around the large disc. During rotation, the readings of the measuring gauge are used to determine whether the levelness of each position on the large disc drive surface is consistent. If the measuring gauge reading changes during calibration, it indicates that the levelness of each position on the large disc drive surface is inconsistent; if the measuring gauge reading does not change during calibration, it indicates that the levelness of each position on the large disc drive surface is consistent. This tool calibrates the flatness of the large disc drive surface, ensuring the flatness of the syringe during circumferential rotation and guaranteeing the accuracy of the needle and diamond-shaped seat.

[0039] The positioning component 3 includes a first moving steel ball positioning screw 31, a second moving steel ball positioning screw 32, and a third moving steel ball positioning screw 33. The bottom of each of the two opposite ends of the telescopic component 2 is fixed with the first moving steel ball positioning screw 31, and the end walls of each of the two opposite ends of the telescopic component 2 are fixed with the second moving steel ball positioning screw 32 and the third moving steel ball positioning screw 33. The second moving steel ball positioning screw 32 is located above the third moving steel ball positioning screw 33. The positioning end of the second moving steel ball positioning screw 32 is located outside the positioning end of the first moving steel ball positioning screw 31, and the positioning end of the third moving steel ball positioning screw 33 is located inside the positioning end of the first moving steel ball positioning screw 31. The measuring end of the first measuring gauge 1 is located inside the positioning end of the third moving steel ball positioning screw 33 and below the positioning end of the first moving steel ball positioning screw 31. The first moving steel ball positioning screw 31 abuts against the diamond-shaped mounting surface of the large disk, and the second moving steel ball positioning screw 32 and the third moving steel ball positioning screw 33 abut against the two inner rings of the large disk, ensuring the smooth rotation of this calibration tool and guaranteeing calibration accuracy.

[0040] The second moving ball positioning screw 32 has a first moving ball positioning screw 31 on both its front and rear sides. By setting two opposing first moving ball positioning screws 31 on each side of the telescopic member 2, the calibration accuracy is further improved.

[0041] The telescopic component 2 includes a first plate 21, a second plate 22, a slide 23, a guide rod 24, and a spring 25. The first plate 21 is fixed to one side of the slide 23, and the second plate 22 is slidably connected to the other side of the slide 23. The second plate 22 has a first guide groove 26 inside. The guide rod 24 is fixed to the inner wall of the first plate 21 and inserted into the first guide groove 26. The spring 25 connects the first plate 21 and the second plate 22. The cooperation between the guide rod 24 and the first guide groove 26 ensures the smooth extension and retraction of the telescopic component 2. The spring 25 pushes the first plate 21 and the second plate 22 outward, ensuring stable contact between the second moving steel ball positioning screw 32 and the third moving steel ball positioning screw 33 and the inner ring of the large disc. Furthermore, the distance between the first plate 21 and the second plate 22 can be adapted to the inner diameter of the large disc, making it widely applicable.

[0042] This includes limiting posts 4. The front and rear side walls of the slide 23 each have a slotted hole 5. Limiting posts 4 are fixed to the front and rear side walls of the second plate 22, passing through the slotted holes 5. The limiting posts 4 restrict the relative adjustment distance between the first plate 21 and the second plate 22, preventing the second plate 22 from sliding out of the slide 23.

[0043] Hooks 9 are fixed to the outer sides of the top walls of both the first plate 21 and the second plate 22. The hooks 9 allow the plate to be hung on rotating equipment, making calibration easier.

[0044] The telescopic component 2 also includes a mounting base 27. The mounting base 27 is detachably connected to the outer side of the bottom wall of both the first plate 21 and the second plate 22. A first directional ball positioning screw 31 is fixed to the first plate 21 and the second plate 22, and a second directional ball positioning screw 32 and a third directional ball positioning screw 33 are both fixed to the mounting base 27. It also includes a mounting frame 10, which is fixed to the side wall of the first plate 21, and a first measuring gauge 1 is fixed to the mounting frame 10. The detachable mounting base 27 allows for easy replacement to change the positions of the second directional ball positioning screw 32 and the third directional ball positioning screw 33 according to different operational needs, providing wide adaptability.

[0045] Example 2:

[0046] like Figures 8 to 9 As shown, the difference between this embodiment and Embodiment 1 is that:

[0047] It also includes a guide block 6 and a second measuring gauge 7. The guide block 6 is fixed to the top wall of the second plate 22, and the top wall of the slide 23 has a second guide groove 8. The second guide block 6 cooperates with the second guide groove. The second measuring gauge 7 is fixed to the top wall of the slide 23, and the measuring end of the second measuring gauge 7 faces the inner wall of the guide block 6. The cooperation between the second measuring gauge 7 and the guide block 6 is used to calibrate the roundness of the inner circle of the large disc, calibrating the roundness of the inner circle of the large disc while calibrating the transmission surface of the large disc.

[0048] In this embodiment, both the first measuring table 1 and the second measuring table 7 are dial gauges.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
