Detailed Description of the Embodiment

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0028] A concentricity measuring table for precision mechanical parts, including an operation table 1, a connecting block and a fixing block 3 are fixedly connected to the top of the operation table 1, a moving block 2 is arranged between the connecting block and the fixing block 3, connecting frames 4 are fixedly connected to the tops of the moving block 2 and the fixing block 3, connecting disks 13 are rotatably connected to the outer surfaces of the two connecting frames 4 close to each other, a concentricity gauge 10 is arranged above the operation table 1, and further includes:

[0029] A flipping assembly, which is located inside one of the connecting frames 4 and is used to drive the connected connecting disk 13 to rotate;

[0030] A clamping assembly, which is located on the outer surfaces of the two connecting disks 13 and is used to clamp both ends of the precision mechanical parts;

[0031] A moving assembly, which is located above the operation table 1 and is used to drive the moving block 2 to move, so as to be applicable to precision mechanical parts of different lengths, and place the parts between the two connecting disks 13.

[0032] Further, the flipping assembly includes a second motor 8, a first gear 11 and a second gear 12. The first gear 11 and the second gear 12 are rotatably connected inside the connecting frame 4. The second gear 12 is located above the first gear 11 and is meshed with the first gear 11. The outer surface of the connecting frame 4 is fixedly installed with the second motor 8. The output end of the second motor 8 is fixedly connected to the first gear 11. The second gear 12 is fixedly connected to the connecting disk 13. The output end of the second motor 8 drives the first gear 11 to rotate. Since the first gear 11 is meshed with the second gear 12, the second gear 12 will also rotate accordingly. Since the second gear 12 is fixedly connected to the connecting disk 13, the connecting disk 13 will rotate with the rotation of the second gear 12, thereby driving the clamped part to flip.

[0033] Further, the clamping assembly includes a clamping block 18, a movable column 19, a fixing ring 20 and a movable groove 22. A fixing ring 20 is fixedly connected to the outer surface of the connecting disc 13. A plurality of annularly and equidistantly distributed movable grooves 22 are formed in the outer surface of the fixing ring 20. A movable column 19 is slidably connected to the inside of each of the plurality of movable grooves 22. A plurality of annularly and equidistantly distributed clamping blocks 18 are slidably connected to the inside of the fixing ring 20. The plurality of clamping blocks 18 are fixedly sleeved with the corresponding movable columns 19. The movable column 19 inside the rotating ring 16 slides in the movable groove 22 of the fixing ring 20, thereby pushing the clamping block 18 to move until the clamping block 18 clamps the part.

[0034] Further, a rotating ring 16 is rotatably connected to the outer surface of the fixing ring 20. The inside of the rotating ring 16 is movably connected to the corresponding movable column 19. Rotate the rotating ring 16.

[0035] Further, a plurality of equidistantly distributed limiting holes 21 are formed in the outer surface of the fixing ring 20. A limiting rod 17 is inserted into the outer surface of the rotating ring 16. The limiting rod 17 is inserted into the corresponding limiting hole 21. By inserting the limiting rod 17 into the limiting hole 21 on the outer surface of the rotating ring 16, the rotating ring 16 is fixed to the fixing ring 20, thereby fixing the position of the clamping block 18.

[0036] Further, the moving assembly includes a threaded rod 5, a limiting column 6 and a first motor 7. A threaded rod 5 is rotatably connected between the connecting block and the fixing block 3. A first motor 7 is fixedly installed on the outer surface of the connecting block. The output end of the first motor 7 is fixedly connected to the threaded rod 5. The threaded rod 5 is sleeved with the moving block 2. Two limiting columns 6 are fixedly connected between the connecting block and the fixing block 3. The threaded rod 5 is located between the two limiting columns 6. The moving block 2 is sleeved with the two limiting columns 6. The output end of the first motor 7 drives the threaded rod 5 to rotate between the connecting block and the fixing block 3. When the threaded rod 5 rotates, the moving block 2 moves along the directions of the threaded rod 5 and the limiting column 6.

[0037] Further, a guide rail 9 is fixedly connected to the top of the operating table 1. A slider 14 is slidably connected to the outer surface of the guide rail 9. The top of the slider 14 is fixedly connected to a mounting frame 15. The mounting frame 15 is rotatably connected to the concentricity gauge 10. Fine adjustment is performed through the combination of the guide rail 9 and the slider 14 to ensure the stability and accuracy during the measurement process.

[0038] Working principle: When the staff needs to use the concentricity measuring table for precision mechanical parts and needs to measure the concentricity of precision mechanical parts, first place the parts between the two connecting plates 13, start the first motor 7, and the output end of the first motor 7 drives the threaded rod 5 to rotate between the connecting block and the fixed block 3. When the threaded rod 5 rotates, the moving block 2 will move along the directions of the threaded rod 5 and the limiting column 6. This moving process enables the distance between the two connecting frames 4 to be adjustable, so as to meet the measurement requirements of parts with different lengths. Rotate the rotating ring 16 so that the movable column 19 inside it slides in the movable groove 22 of the fixed ring 20, and then push the clamping block 18 to move until the clamping block 18 clamps the parts. Insert the limiting rod 17 into the limiting hole 21 on the outer surface of the rotating ring 16 to fix the rotating ring 16 on the fixed ring 20, thereby fixing the position of the clamping block 18 and realizing the stable clamping of the parts. After the clamping component fixes the parts, start the second motor 8, and the output end of the second motor 8 drives the first gear 11 to rotate. Since the first gear 11 is meshed and connected with the second gear 12, the second gear 12 will also rotate accordingly. Since the second gear 12 is fixedly connected with the connecting plate 13, the connecting plate 13 will rotate with the rotation of the second gear 12, and then drive the clamped parts to flip. This flipping process helps to measure the concentricity of the parts in all directions and improve the measurement accuracy. During the process of the parts being stably clamped and adjusted to the appropriate position and then rotated, start the concentricity meter 10 for measurement. The concentricity meter 10 accurately measures the concentricity of the parts through the principle of laser interferometer or other high-precision measurement techniques inside it.

[0039] The concentricity meter 10 is usually rotatably connected to the mounting frame 15 and can be finely adjusted through the combination of the guide rail 9 and the slider 14 to ensure the stability and accuracy during the measurement process. The measurement results will be displayed on the display screen of the concentricity meter 10 in real time for the operator to view and record.

[0040] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
