Description

Technical Field

[0001] The invention belongs to the technical field of planetary carrier assembly, in particular to a planetary carrier assembly device. Background Art

[0002] The planetary carrier assembly device is a special equipment used to assemble the core components of planetary gear transmission systems. Through high-precision positioning, intelligent press-fitting and online detection technology, it ensures the assembly quality of key components such as planetary gears and pins. It has the advantages of high degree of automation, high assembly accuracy (coaxiality ≤ 0.02mm) and controllable quality. It is widely used in automotive gearboxes, industrial reducers and other fields.

[0003] Before assembling the planetary carrier assembly, it is necessary to remove metal chips, oil stains and other contaminants on the surface of the parts. Otherwise, the residual metal chips and oil stains will destroy the precision fit, causing the assembly accuracy to drop by more than 50%, resulting in eccentric wear and abnormal vibration of the planetary gears. In addition, the contaminants will change the friction characteristics, causing the pressing force to fluctuate by more than 30%, seriously affecting the assembly quality. For example, the public patent: CN202210822873.5 Planetary carrier copper sleeve assembly method records that the planetary carrier assembly needs to be cleaned before assembly, and it is cleaned by ultrasonic cleaning equipment. In this process, the cleaned parts need to be transferred to the pressing station manually or by a robot.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figures 1 to 7 As shown, a planet carrier assembly assembly device according to an embodiment of the present invention includes a workbench 1 and an assembly table 2 arranged on the workbench 1;

[0033] A cleaning station 3 is provided on one side of the assembly station 2. The interior of the cleaning station 3 is divided into a first chamber 34 and a second chamber 35 by a partition 4. An ultrasonic generator is provided inside the second chamber 35.

[0034] Clean water is stored in both the first chamber 34 and the second chamber 35 , and the first chamber 34 and the second chamber 35 are prevented from communicating with each other by the partition 4 .

[0035] A cleaning frame 9 is provided on the partition 4 and is located in the first chamber 34. A carrier 18 for placing the planetary carrier assembly is slidably mounted inside the cleaning frame 9. The outer wall of the carrier 18 is in contact with the inner wall of the cleaning frame 9. A lifting assembly is provided on the cleaning frame 9 for controlling the carrier 18 to be raised or lowered on the inner wall of the cleaning frame 9.

[0036] First, place the planetary carrier assembly to be cleaned on the carrier platform 18, and then lower the carrier platform 18 to the inside of the second chamber 35 through the provided lifting assembly. At this time, start the ultrasonic generator to clean the planetary carrier assembly, and the assembly table 2 is located on one side of the cleaning table 3. After the planetary carrier assembly is cleaned, it can be taken out directly for assembly, which improves the assembly efficiency and reduces the secondary contamination of the planetary carrier assembly during transportation.

[0037] A blocking ring plate 31 is slidably mounted inside the cleaning frame 9. The outer wall of the blocking ring plate 31 fits in contact with the interior of the cleaning frame 9. A first drainage hole 30 is formed on the cleaning frame 9, and a second drainage hole 32 is formed on the blocking ring plate 31. By moving the blocking ring plate 31, the first drainage hole 30 and the second drainage hole 32 are aligned, allowing the clean water inside the first chamber 34 to enter the interior of the cleaning frame 9.

[0038] A protrusion 33 is elastically mounted on the blocking ring plate 31 , one end of the protrusion 33 extends into the interior of the cleaning frame 9 , and the top and bottom ends of the protrusion 33 are both inclined.

[0039] After the carrier platform 18 drives the planetary carrier assembly to be ultrasonically cleaned in the second chamber 35 through the lifting component, the carrier platform 18 is lifted to the inside of the cleaning frame 9. At this time, the carrier platform 18 will block the bottom of the cleaning frame 9, and when the carrier platform 18 slides upward inside the cleaning frame 9, it will push the protrusion 33 and drive the blocking ring plate 31 to slide upward inside the cleaning frame 9, so that the first drainage hole 30 corresponds to the second drainage hole 32. At this time, the clean water in the first chamber 34 will pass through the first drainage hole 30 and the second drainage hole 32 into the interior of the cleaning frame 9 until the liquid level is higher than the planetary carrier assembly, completing the clean water immersion cleaning, and can rinse impurities attached to the surface after ultrasonic cleaning, further improving the cleaning effect of the planetary carrier assembly.

[0040] A receiving ring 10 is provided on the cleaning frame 9 , and a water outlet pipe 11 is provided on the receiving ring 10 . The other end of the water outlet pipe 11 passes through the partition 4 and extends to the interior of the second chamber 35 .

[0041] After cleaning is completed, the lifting assembly is used to control the supporting platform 18 to slide inside the cleaning frame 9 again. As the supporting platform 18 continues to slide up, the inclined surface set at the bottom of the protrusion 33 will be pressed, and the protrusion 33 will be pushed into the inside of the blocking ring plate 31. Under the action of gravity, it slides downward inside the cleaning frame 9, so that the first drainage hole 30 and the second drainage hole 32 are misaligned, closing the channel for the clean water inside the first chamber 34 to enter the cleaning frame 9. During the sliding process of the supporting platform 18, the water inside the cleaning frame 9 will be pushed out and received by the set receiving ring 10. At the same time, the sewage will be re-sent into the inside of the second chamber 35 through the set outlet pipe 11, completing the cycle, so that the water in the first chamber 34 is always kept clean.

[0042] As a preferred embodiment of the present invention, the lifting assembly includes a winding rod 13, a connecting rope 15 and a drive motor 16. The winding rod 13 is rotatably installed on the receiving ring 10. One end of the connecting rope 15 is wrapped around the winding rod 13, and the other end is connected to the supporting platform 18. The drive motor 16 is fixedly installed at the bottom end of the receiving ring 10, and the output shaft of the drive motor 16 is fixedly connected to the winding rod 13.

[0043] A gear ring 12 is rotatably installed inside the receiving ring 10, and a transmission gear 14 that meshes with the gear ring 12 is fixedly installed at the bottom end of the winding rod 13. There are multiple winding rods 13 and transmission gears 14, which are arranged in a ring array inside the receiving ring 10 and are all meshed with the gear ring 12.

[0044] One of the winding rods 13 can be connected to the drive motor 16. With the cooperation of the gear ring 12, multiple transmission gears 14 can rotate at the same time, and drive multiple winding rods 13 to reel or unreel at the same time. When multiple winding rods 13 reel the connecting rope 15 at the same time, they can drive the supporting platform 18 to slide up inside the cleaning frame 9. When multiple winding rods 13 rotate to unreel the connecting rope 15, with the assistance of the weight of the planetary frame assembly, the supporting platform 18 can slide downward inside the cleaning frame 9.

[0045] As a preferred embodiment of the present invention, a swivel 21 is rotatably installed on the supporting platform 18, and the end of the connecting rope 15 away from the winding rod 13 is fixedly connected to the control ring 17. A connecting rod 20 is rotatably installed on the bottom of the control ring 17, and the other end of the connecting rod 20 is fixedly connected to the swivel 21. There are multiple connecting rods 20, and the multiple connecting rods 20 are arranged in a ring at equal intervals.

[0046] When the drive motor 16 is started and the control winding rod 13 is controlled to rotate, the control ring 17 will be pulled to move. Under the action of multiple connecting rods 20, the control ring 17 will drive the supporting platform 18 to move. In addition, through the cooperation of the control ring 17, multiple connecting rods 20 and the supporting platform 18, the planetary carrier assembly can also be limited, effectively avoiding the deviation of the planetary carrier assembly during cleaning.

[0047] A rotating ring 26 with a cavity is rotatably installed inside the control ring 17, and a plurality of blades 27 are fixedly installed on the top of the rotating ring 26. A circulating pump 5 is provided on the washing table 3. The input end of the circulating pump 5 extends to the inside of the second chamber 35 through the water inlet pipe 7, and the output end of the circulating pump 5 extends to the inside of the control ring 17 through the drain pipe 8. One end of the drain pipe 8 is inclined toward the blades 27, and a filter screen 6 is provided inside the second chamber 35.

[0048] A water leakage hole 28 is opened at the top of the rotating ring 26 . The connecting rod 20 is hollow, and one end of the connecting rod 20 extends to the inside of the rotating ring 26 . The connecting rod 20 is opened with a plurality of water spray holes.

[0049] The impurities in the water in the second chamber 35 can be filtered by the filter 6. When the circulation pump 5 is started, the water in the second chamber 35 is pumped out through the water inlet pipe 7 and sent to the inside of the control ring 17 through the drain pipe 8. Since the drain pipe 8 is tilted toward one end of the blade 27, the water discharged from the drain pipe 8 will impact the multiple blades 27 in sequence. At this time, the multiple blades 27 will drive the rotating ring 26 to rotate inside the control ring 17 under the impact of the water flow. At the same time, the multiple connecting rods 20 are fixedly connected to the rotating ring 26. Therefore, when the water flow flushes the blades 27, the rotating ring 26 When the rotating ring 26 rotates, it can drive the multiple connecting rods 20 to rotate along the axis of the rotating ring 26. The water flow that impacts the blades 27 can enter the inner cavity of the rotating ring 26 through the leakage hole 28 opened at the top of the rotating ring 26, and then enter the interior of the connecting rods 20. Finally, under the action of water pressure, the water is discharged from the water spray hole toward the planetary carrier assembly. When the planetary carrier assembly is ultrasonically cleaned in the second chamber 35, the dirt around the planetary carrier assembly can be washed away. In addition, the rotating ring 26 can drive the multiple connecting rods 20 to spray around the planetary carrier assembly, thereby reducing blind spots in the spraying and improving the cleaning effect of the planetary carrier assembly.

[0050] As a preferred embodiment of the present invention, a positioning block 25 is fixedly installed on the inner wall of the control ring 17, a floating net 19 is slidably installed on the supporting platform 18, a winding roller 22 is rotatably installed on the supporting platform 18, a pull rope 29 is fixedly connected to the top of the floating net 19, and the other end of the pull rope 29 passes through the positioning block 25 and is fixedly connected to the winding roller 22, a rotating gear 23 is fixedly installed on the winding roller 22, and an intermittent tooth plate 24 engaged with the rotating gear 23 is fixedly installed on the rotating ring 21, and a plurality of pull ropes 29, winding rollers 22, rotating gears 23 and intermittent tooth plates 24 are provided.

[0051] The plurality of intermittent tooth plates 24 are engaged with or not engaged with the plurality of rotating gears 23 at the same time. Therefore, when the circulation pump 5 is started and water is sent into the interior of the control ring 17, the discharged water flow will impact the plurality of blades 27 in sequence, driving the rotating ring 26 to rotate inside the control ring 17, and at the same time making the plurality of connecting rods 20 drive the rotating ring 21 to rotate on the bearing platform 18, and at the same time driving the intermittent tooth plates 24 to rotate on the bearing platform 18, and the plurality of intermittent tooth plates 24 are engaged with the plurality of rotating gears 23 at the same time, driving the plurality of winding rollers 22 to wind up the pull rope 29 at the same time, and the floating net 19 and the plurality of rollers 22 on the floating net 19 can be wound. The planetary carrier assembly on the moving net 19 is pulled up. After being pulled up, the blind area where the planetary carrier assembly fits with the bottom surface of the supporting platform 18 can be cleaned by ultrasonic waves. At the same time, multiple connecting rods 20 can also spray the planetary carrier assembly in all aspects. In the process of the planetary carrier assembly floating up and down underwater, the water flow will pass through the pores of the planetary carrier assembly from bottom to top, and wash away the dirt to be washed. When the multiple intermittent tooth plates 24 are no longer engaged with the rotating gear 23, the planetary carrier assembly drives the floating net 19 to slide downward under the action of gravity. By repeating the above steps, the cleaning effect of the planetary carrier assembly can be further improved.

[0052] Working principle: By starting the drive motor 16, the transmission gear 14 controls the winding rod 13 to rotate under the action of the gear ring 12, and the carrier 18 carrying the planetary carrier assembly is lowered to the inside of the second chamber 35 for ultrasonic cleaning, and then the carrier 18 is lifted to the inside of the cleaning frame 9. At this time, the carrier 18 will block the bottom of the cleaning frame 9, and at the same time push the protrusion 33 and drive the blocking ring plate 31 to slide upward inside the cleaning frame 9, so that the first drainage hole 30 corresponds to the second drainage hole 32. At this time, the clean water in the first chamber 34 will pass through the first drainage hole 30 and the second drainage hole 32 into the inside of the cleaning frame 9 until the liquid level is higher than the planetary carrier assembly, completing the clean water immersion cleaning, and can rinse impurities attached to the surface after ultrasonic cleaning, further improving the cleaning effect of the planetary carrier assembly.

[0053] Then the circulation pump 5 is started, and the water in the second chamber 35 is pumped out through the water inlet pipe 7, and is sent into the interior of the control ring 17 through the drain pipe 8, impacting the multiple blades 27 in sequence, driving the rotating ring 26 to rotate inside the control ring 17. The water flow that impacts the blades 27 can enter the inner cavity of the rotating ring 26 through the leakage hole 28 opened at the top of the rotating ring 26, and enter the interior of the connecting rod 20. The multiple connecting rods 20 surround the planetary carrier assembly for spraying, and wash away the dirt lingering around the planetary carrier assembly, reducing the blind angle of the spraying, and improving the cleaning effect of the planetary carrier assembly.

[0054] At the same time, when the water flow impacts the multiple blades 27 in sequence, driving the rotating ring 26 to rotate inside the control ring 17, the multiple connecting rods 20 drive the rotating ring 21 to rotate on the carrier 18, and the intermittent gear plate 24 also rotates on the carrier 18. When the multiple intermittent gear plates 24 are engaged with the multiple rotating gears 23 at the same time, the multiple winding rollers 22 are driven to reel in the pull rope 29 at the same time. At this time, the floating net 19 and the planetary carrier assembly on the floating net 19 can be pulled up. After being pulled up, the planetary carrier assembly and the carrier 18 are connected. The blind area where the bottom surface is fitted can be cleaned by ultrasonic waves. At the same time, multiple connecting rods 20 can also spray the planetary carrier assembly in all aspects. In the process of the planetary carrier assembly floating up and down underwater, the water flow will pass through the pores of the planetary carrier assembly from bottom to top, and wash away the dirt to be washed. When the multiple intermittent tooth plates 24 are not engaged with the rotating gear 23, the planetary carrier assembly drives the floating net 19 to slide downward under the action of gravity. By repeating the above steps, the cleaning effect of the planetary carrier assembly can be further improved.
