During use, the base 1 is fixedly installed on the machine tool bed, the rotating shaft passes through the middle of the upper half ring 4 and the lower half ring 3, and the centers of the three vibration absorption adjusters 5 on the vibration absorption assembly are quickly aligned through the horizontal adjustment assembly, the lateral adjustment assembly, and the lifting assembly, and then the center of the rotating shaft is finally aligned by finely adjusting the vibration absorption adjuster 5.

[0039] By setting up a horizontal adjustment component, a lateral adjustment component, a lifting component and a vibration absorption component, it can be installed conveniently and quickly, quickly align the center of the rotating shaft, with a low learning curve and is relatively easy for novices to master.

[0040] As Figure 1 shown, the lifting component includes a mounting plate 11 which is slidably mounted on the top of the arc-shaped plate 7. A hydraulic cylinder 2 is fixedly mounted on the top of the mounting plate 11, and the top end of the hydraulic cylinder 2 is fixedly connected to the lower half-ring 3. During use, start the hydraulic cylinder 2 to make the output shaft extend. The start of the hydraulic cylinder 2 drives the lower half-ring 3 to rise, and the rise of the lower half-ring 3 drives the upper half-ring 4 to rise, so that the entire vibration absorption component rises.

[0041] By setting up the lifting component, it is convenient to lift the vibration absorption component.

[0042] As Figure 1 shown, two rollers 8 are rotatably mounted in the arc-shaped groove. The arc-shaped plate 7 is in contact with the two rollers 8. An arc-shaped rack 10 is fixedly mounted at the bottom of the arc-shaped plate 7. A first gear 9 is rotatably mounted in the mounting groove, and the first gear 9 meshes with the arc-shaped rack 10. During use, rotate the first gear 9. The rotation of the first gear 9 drives the arc-shaped rack 10 to rotate, and the rotation of the arc-shaped rack 10 drives the arc-shaped plate 7 to rotate until the arc-shaped plate 7 is horizontal.

[0043] By setting two rollers 8, an arc-shaped rack 10 and a first gear 9, it is convenient to adjust the arc-shaped plate 7 to be horizontal.

[0044] As Figure 4 shown, a worm gear 15 is fixedly mounted on the lead screw 14. A worm 16 is rotatably mounted in the mounting groove. The worm 16 meshes with the worm gear 15. The top end of the worm 16 extends outside the arc-shaped plate 7, and a handle is fixedly mounted at the top end of the worm 16. During use, turn the handle from above to make the worm 16 rotate. The rotation of the worm 16 drives the worm gear 15 to rotate, and the rotation of the worm gear 15 drives the lead screw 14 to rotate.

[0045] By setting the worm gear 15 and the worm 16, it is convenient to rotate the lead screw 14.

[0046] As Figure 5 and Figure 6As shown, the vibration absorber regulator 5 includes a fixed pipe 17 which penetrates through the lower half ring 3 or the upper half ring 4 and is fixedly connected to the lower half ring 3 or the upper half ring 4. A rotating pipe 18 is rotatably installed in the fixed pipe 17. A shock-absorbing pipe 19 is threadedly installed in the rotating pipe 18. A thimble 20 is slidably installed in the shock-absorbing pipe 19. A dial indicator 21 is provided at the top end of the shock-absorbing pipe 19. A friction ring 22 is fixedly installed at the bottom end of the shock-absorbing pipe 19. The bottom end of the thimble 20 penetrates through the friction ring 22. During use, hold the shock-absorbing pipe 19 with one hand and hold the rotating pipe 18 with the other hand and rotate it. The rotation of the rotating pipe 18 drives the shock-absorbing pipe 19 to descend. The descent of the rotating pipe 19 drives the thimble 20 to descend. The thimble 20 contacts the rotating shaft. The eccentric rotating shaft causes the thimble 20 to rise. The rise of the thimble 20 drives the dial indicator 21 to display a reading. By adjusting according to the reading differences of the three dial indicators 21 until the readings of the three dial indicators 21 are the same, then continue to rotate the rotating pipe 18 to make the friction ring 22 contact the rotating shaft and press the rotating shaft to align it.

[0047] By providing the vibration absorber regulator 5, it is convenient to align the center of the rotating shaft.

[0048] As Figure 5 shown, a first spring 23 is installed on the thimble 20. The dial indicator 21 contacts the top end of the thimble 20. During use, when the processing is completed, the first spring 23 drives the thimble 20 to descend to the initial position and also makes the dial indicator 21 return to zero.

[0049] By providing the straight rack 12 and the second gear 6, it is convenient for the dial indicator 21 to return to zero.

[0050] As Figure 5 shown, two chutes are provided at the top end of the shock-absorbing pipe 19. Straight racks 12 are slidably installed in the two chutes. The two straight racks 12 are fixedly connected to the dial indicator 21. Second gears 6 are rotatably installed in the two chutes. The two second gears 6 are meshed with the corresponding straight racks 12. During use, rotate the second gear 6. The rotation of the second gear 6 drives the straight rack 12 to rise. The rise of the straight rack 12 drives the dial indicator 21 to rise. The rise of the dial indicator 21 separates from the thimble 20, making the dial indicator 21 return to zero.

[0051] By providing the straight rack 12 and the second gear 6, it is convenient to zero the dial indicator.

[0052] As Figure 7 shown, the friction ring 22 is provided with a plurality of counterbores. Screws are installed in the plurality of counterbores. The friction ring 22 is fixedly connected to the shock-absorbing pipe 19 through the screws. During use, after unscrewing the screws, the damaged friction ring 22 can be replaced.

[0053] By setting a friction ring 22 fixed with screws, it is convenient to replace the friction ring 22, and at the same time, a suitable friction ring 22 can be rotated according to the size of the rotating shaft.

[0054] As Figure 4 and Figure 8 shown, a limiting tube 24 is slidably mounted on the worm 16. The limiting tube 24 is fixedly mounted on the top of the arc-shaped plate 7. A clamping tube 25 is fixedly mounted on one side of the limiting tube 24. A T-shaped rod 26 is provided on one side of the limiting tube 24. The T-shaped rod 26 penetrates through the limiting tube 24 and the clamping tube 25 and is slidably connected to the limiting tube 24 and the clamping tube 25. A second spring 27 is mounted on the T-shaped rod 26. During use, pull the T-shaped rod 26 to move the T-shaped rod 26. The movement of the T-shaped rod 26 compresses the second spring 27 and disengages from the worm 16. At this time, the worm 16 can be rotated. When the rotation is completed and the hand is released, under the action of the second spring 27, the T-shaped rod 26 presses on the worm 16 to prevent the worm 16 from rotating.

[0055] By setting the limiting tube 24, the clamping tube 25, the T-shaped rod 26 and the second spring 27, it is convenient to fix the worm 16.

[0056] As Figure 8 and Figure 9 shown, a bayonet slot is formed on one side of the clamping tube 25. A pin rod 28 is fixedly mounted on one side of the T-shaped rod 26. The pin rod 28 is adapted to the bayonet slot. During use, pull the T-shaped rod 26 and rotate it by a certain angle so that the pin rod 28 is stuck outside the bayonet slot. When the worm moves to the end, rotate it again, align the pin rod 28 with the buckle slot and release the hand.

[0057] By setting the bayonet slot and the pin rod 28, it is convenient to fix the T-shaped rod 26.

[0058] The working principle of the adjusting mechanism of the vibration absorption device for motor stator production provided by the present invention is as follows:

[0059] First, the base 1 is fixed inside the lathe bed (below the guide rail), the hydraulic cylinder 2 is connected to the hydraulic pump, and the first gear 9 is connected to the motor through a reduction box;

[0060] Start the motor to rotate the first gear 9. The rotation of the first gear 9 drives the arc-shaped rack 10 to rotate. The rotation of the arc-shaped rack 10 drives the arc-shaped plate 7 to rotate until the arc-shaped plate 7 is horizontal; the horizontal adjustment is completed;

[0061] Start the hydraulic pump to raise the output shaft of the hydraulic cylinder 2. The start of the hydraulic cylinder 2 drives the lower half ring 3 and the upper half ring 4 to rise until the center of the ring formed by the two half rings is basically horizontally aligned with the main shaft;

[0062] Pull the T-shaped rod 26 and rotate it by a certain angle so that the pin rod 28 is stuck outside the bayonet slot. Then, rotate the handle from above to make the worm 16 rotate. The rotation of the worm 16 drives the worm wheel 15 to rotate. The rotation of the worm wheel 15 drives the lead screw 14 to rotate. The rotation of the lead screw 14 drives the slider 13 to move. The movement of the slider 13 drives the mounting plate 11 to move until the center of the ring is basically coincident with the center of the main shaft. Then, rotate the T-shaped rod 26 again, align the pin rod 28 with the buckle slot and release the hand;

[0063] Rotate the second gear 6. The rotation of the second gear 6 drives the straight rack 12 to rise. The rise of the straight rack 12 drives the dial indicator 21 to rise. The rise of the dial indicator 21 disengages from the thimble 20, making the dial indicator 21 return to zero. Finally, lock the straight rack 12 with screws;

[0064] Hold the shock-absorbing tube 19 with one hand and hold the rotating tube 18 with the other hand and rotate it. The rotation of the rotating tube 18 drives the shock-absorbing tube 19 to descend. The descent of the shock-absorbing tube 19 drives the thimble 20 to descend. The thimble 20 contacts the rotating shaft. The eccentric rotating shaft makes the thimble 20 rise. The rise of the thimble 20 drives the dial indicator 21 to display a reading. By comparing the reading differences of the three dial indicators 21, adjust the rotating tube 18 until the readings of the three dial indicators 21 are the same. Then, continue to rotate the rotating tube 18 synchronously (the same number of turns) so that the friction ring 22 contacts the rotating shaft and presses the rotating shaft to align it. Finally, lock the rotating tube 18 with screws;

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
