[0031] See also Figures 1 to 8 The present invention provides a technical solution: a gear maintenance device for mechanical design and manufacturing, comprising a shell 1, a cleaning chamber 2 and an equipment chamber 3 are provided inside the shell 1, a controller 4 is provided on the side of the shell 1, and the maintenance device comprises a multiple cleaning mechanism, a lubrication protection mechanism and a positioning and rotating mechanism. The multiple cleaning mechanism uses a steel wire rope 14 to loosen the stubborn oil stains attached to the corners of a gear part 17, so that the cleaning brush 9 and the spray head 11 can be used to brush and clean the gear part 17 without dead angles. The lubrication protection mechanism uses the action of the steel wire rope 14 to clean the gear part 17 to spray lubricating oil on the steel wire rope 14. The positioning and rotating mechanism can position the gear part 17 in the middle of the steel wire rope 14, so that the steel wire rope 14 can accurately fit the outer side of the gear part 17, and can also drive the gear part 17 to rotate.

[0032] As an embodiment of the present invention, Figure 3 and Figure 4 as well as Figure 5As shown, the multiple cleaning mechanism includes a first servo motor 5 arranged at the upper end of the shell 1, the first servo motor 5 drives the first bidirectional screw 6 to rotate, the outer side of the first bidirectional screw 6 is threadedly connected to the first movable frame 7 and the second movable frame 8, the first movable frame 7 is fixedly connected to a cleaning brush 9 on the side close to the center of the shell 1, a spray head 11 is arranged above the cleaning brush 9, the right side of the spray head 11 is fixedly connected to a water supply pipe 10, the water supply pipe 10 is clamped on the first movable frame 7, the second movable frame 8 is fixedly connected to a fixed plate 12 on the side close to the center of the shell 1, and two sets of sliders are slidably connected to the fixed plate 12 13, a steel wire rope 14 is fixedly connected between the two sets of sliders 13, and the steel wire rope 14 is attached to the outside of the two sets of pulleys 15. The pulleys 15 are fixedly installed on the fixed plate 12, and a return spring 16 is arranged between the fixed plate 12 and the slider 13. The controller 4 controls the first servo motor 5 to start, and the first servo motor 5 drives the first bidirectional screw rod 6 to rotate, so that the first bidirectional screw rod 6 drives the first movable frame 7 and the second movable frame 8 to move toward each other, so that the cleaning brush 9 on the first movable frame 7 and the steel wire rope 14 on the second movable frame 8 contact the outside of the gear part 17, and the water supply pipe 10 provides the sprinkler head 11 with The water source allows the spray head 11 to flush the gear part 17, thereby combining with the cleaning brush 9 to achieve brushing. Then, when the gear part 17 rotates, the gear part 17 drives the wire rope 14 to swing along the outer sawtooth, and the wire rope 14 drives the slider 13 to slide through the pulley 15, so that the wire rope 14 can be stretched and adjusted. Then, the restoring force of the reset spring 16 drives the wire rope 14 to restore its position through the slider 13, so that the wire rope 14 is always closely attached to the outer side of the gear part 17, which is conducive to using the wire rope 14 to loosen the stubborn oil attached to the corner of the sawtooth of the gear part 17, which is convenient for cleaning the brush 9. The subsequent brushing with the spray head 11 can greatly improve the cleaning effect of the gear part 17. By adjusting the position of the wire rope 14 and the cleaning brush 9, it is convenient to clean and maintain the gear parts 17 of different diameters. The reset spring 16 is set to not only help the adjusted wire rope 14 to quickly return to the position that fits the outside of the gear part 17, but also ensure that the wire rope 14 does not need to have elastic properties, thereby broadening its optional material range. This design not only stabilizes the performance of the wire rope 14 in loosening oil stains, but also effectively extends its service life, thereby realizing an economical and efficient cleaning solution.

[0033] As an embodiment of the present invention, Figure 3 and Figure 4 as well as Figure 6As shown, the lubrication protection mechanism includes a telescopic oil bag 18 sleeved on the steel wire rope 14, and the two ends of the telescopic oil bag 18 are respectively fixedly connected to the fixed plate 12 and the slider 13, and the side of the telescopic oil bag 18 is fixedly connected to one end of the oil delivery pipe 19, and the other end of the oil delivery pipe 19 passes through the shell 1 and the fixed plate 12 and is fixedly connected to the bottom end of the oil storage tank 20. The side of the telescopic oil bag 18 is fixedly connected to an oil outlet pipe 21, and the oil outlet pipe 21 is provided with an oil spray head 22. The oil delivery pipe 19 and the oil outlet pipe 21 are both provided with a one-way valve 23, and the one-way valve 23 is fixedly installed on the fixed plate 12. When the sawtooth on the outer side of the gear member 17 drives the steel wire rope 14 to swing, the steel wire rope 14 drives the slider 13 to squeeze the telescopic oil bag 18, so that the telescopic oil bag 18 shrinks, thereby the inside of the telescopic oil bag 18 The lubrication is delivered to the oil spray head 22 through the oil outlet pipe 21, and then the oil spray head 22 sprays the gear part 17. Then the restoring force of the reset spring 16 drives the telescopic oil bag 18 to extend through the slider 13, so that the telescopic oil bag 18 sucks the lubricating oil in the oil storage tank 20 into the telescopic oil bag 18 through the oil delivery pipe 19, thereby replenishing the lubricating oil, and preventing the lubricating oil from flowing back through the one-way valve 23, which is beneficial to the process of using the wire rope 14 to clean the gear part 17, and intermittently spraying the lubricating oil for the gear part 17, which is convenient for reducing the friction between the wire rope 14 and the gear part 17, reducing the wear of the gear part 17 and extending the service life of the wire rope 14, and the last turn of the wire rope 14 can evenly apply lubricating oil to the gear part 17, which is convenient for the subsequent use of the gear part 17.

[0034] As an embodiment of the present invention, Figure 2 and Figure 7 as well as Figure 8As shown, the positioning and rotating mechanism includes a center disk 24 rotatably connected to the cleaning chamber 2, a clamping strip 25 is fixedly installed at the front end of the center disk 24, and a large gear 26 is fixedly connected to the rear end of the center disk 24 through the rotating drum, and the large gear 26 is arranged in the equipment chamber 3. A driving motor 27 is fixedly installed at the rear end of the equipment chamber 3, and a small gear 28 is fixedly installed on the output shaft of the driving motor 27, and the small gear 28 is meshed with the large gear 26. A second servo motor 29 is fixedly installed at the rear end of the large gear 26. The output shaft of the servo motor 29 passes through the center disk 24 and the large gear 26 and is fixedly connected with a second bidirectional screw rod 30. The outer side of the second bidirectional screw rod 30 is threadedly connected with two groups of symmetrical movable blocks 31. The outer side of the movable block 31 is provided with a card slot 32. The card slot 32 is provided with a card strip 25. The card strip 25 is adapted to the card slot 32. The outer side of the movable block 31 is hinged with one end of a connecting rod 33. The other end of the connecting rod 33 is hinged with a card head 34. The three groups of card heads 34 are commonly clamped with a gear member 17. When in use, first pass The controller 4 controls the second servo motor 29 to start. Because the card strip 25 is provided in the card slot 32 on the movable block 31, the rotation direction of the movable block 31 is restricted. Therefore, the second servo motor 29 drives the two groups of movable blocks 31 to move toward each other. Then, because the two groups of movable blocks 31 are hinged with the card head 34 through the connecting rod 33, the three groups of card heads 34 move outward, so that the three groups of card heads 34 fix the gear part 17, and the gear part 17 can always be located between the two groups of pulleys 15, which is convenient for the steel wire rope 14 to stick to the steel wire rope 14. Finally, the controller 4 controls the drive motor 27 to start, and the drive motor 27 drives the gear part 17 at the front end of the center disk 24 to slow down and rotate through the small gear 28 and the large gear 26, which is beneficial to centering the gear parts 17 of different diameters, so that the gear part 17 can be stably fixed to the front end of the center disk 24, which is convenient for the gear part 17 to rotate with the center disk 24, and the gear part 17 can be placed in the middle section of the wire rope 14, reserving space for the movement of the pulley 15, so as to facilitate the fitting of the wire rope 14.

[0035] Working principle: When in use, first start the second servo motor 29 through the controller 4. Since the card strip 25 is provided in the card slot 32 on the movable block 31, the rotation direction of the movable block 31 is limited, so that the second servo motor 29 can drive the two groups of movable blocks 31 to move toward each other. Then, since the two groups of movable blocks 31 are hinged with the card head 34 through the connecting rod 33, the three groups of card heads 34 will move outward and tightly fix the gear part 17. This design limits the vertical position of the gear part 17, ensuring that the gear part 17 is always located between the two groups of pulleys 15, so that the wire rope 14 can fit it. Then the controller 4 plays a role again and starts the drive motor 27. The drive motor 27 drives the gear part 17 at the front end of the center disk 24 to rotate in a decelerated manner through the transmission of the small gear 28 and the large gear 26.

[0036] The controller 4 controls the first servo motor 5 to start, and the first servo motor 5 drives the first bidirectional screw rod 6 to rotate, so that the first bidirectional screw rod 6 drives the first movable frame 7 and the second movable frame 8 to move toward each other, so that the cleaning brush 9 on the first movable frame 7 and the steel wire rope 14 on the second movable frame 8 contact the outer side of the gear part 17, and the water supply pipe 10 provides a water source for the sprinkler head 11, so that the sprinkler head 11 can flush the gear part 17, thereby combining with the cleaning brush 9 to achieve brushing, and then when the gear part 17 rotates, the gear part 17 drives the steel wire rope 14 to swing along the outer sawtooth, and the steel wire rope 14 drives the slider 13 to slide through the pulley 15, so that the steel wire rope 14 can be stretched and adjusted, and then the restoring force of the reset spring 16 drives the steel wire rope 14 to restore its position through the slider 13, so that the steel wire rope 14 is always close to the outer side of the gear part 17;

[0037] When the serrations on the outside of the gear part 17 drive the wire rope 14 to swing, the wire rope 14 drives the slider 13 to squeeze the telescopic oil bag 18, causing the telescopic oil bag 18 to shrink, so that the lubrication inside the telescopic oil bag 18 is delivered to the oil spray head 22 through the oil outlet pipe 21, and then the oil spray head 22 sprays the gear part 17, and then the restoring force of the return spring 16 drives the telescopic oil bag 18 to extend through the slider 13, so that the telescopic oil bag 18 sucks the lubricating oil in the oil storage tank 20 into the telescopic oil bag 18 through the oil delivery pipe 19, thereby replenishing the lubricating oil, and preventing the lubricating oil from flowing back through the one-way valve 23.
