Description

Technical Field

[0001] The present invention belongs to the technical field of planet carrier assembly, and specifically relates to a planet carrier assembly device. Background Art

[0002] The planet carrier assembly device is a special equipment for assembling the core components of a planetary gear transmission system. Through high-precision positioning, intelligent press-fitting and on-line detection technologies, it ensures the assembly quality of key components such as planet gears and pin shafts, and has advantages such as high automation, high assembly precision (coaxiality ≤ 0.02 mm) and controllable quality, and is widely used in fields such as automotive transmissions and industrial speed reducers.

[0003] Before assembling the planet carrier assembly, it is necessary to remove contaminants such as metal chips and oil stains on the surface of the parts. Otherwise, the residual metal chips and oil stains will damage the precise fit, reduce the assembly precision by more than 50%, cause eccentric wear and abnormal vibration of the planet gears, and moreover, the contaminants will change the friction characteristics, resulting in a press-fitting force fluctuation exceeding 30%, seriously affecting the assembly quality. As recorded in the published patent: CN202210822873.5 Planet Carrier Copper Sleeve Assembly Method, it is necessary to clean the planet carrier assembly before assembling the planet carrier assembly, and it is cleaned by an ultrasonic cleaning device. In this process, the parts after cleaning need to be transported to the press-fitting station manually or by a manipulator, and in this process, the surface of the parts is extremely vulnerable to secondary contamination by contaminants such as dust and oil mist in the environment, thereby affecting the assembly quality.

The output end of the circulating pump extends to the inside of the control ring through a drain pipe. One end of the drain pipe is inclined towards the blades. A filter screen is arranged inside the second chamber.

[0016] A water leakage hole is opened at the top end of the rotating ring. The connecting rod is hollow. One end of the connecting rod extends to the inside of the rotating ring, and multiple water spraying holes are opened on the connecting rod.

The pull rope, the winding roller, the rotating gear, and the intermittent toothed plate are all provided in plurality.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. For an assembly device of a planet carrier assembly according to the present invention, when the drive motor is started and the drive gear controls the winding rod to rotate under the action of the toothed ring, the carrier table carrying the planet carrier assembly is lowered into the interior of the second chamber for ultrasonic cleaning. Subsequently, the carrier table is lifted into the interior of the cleaning frame. At this time, the carrier table will block the bottom of the cleaning frame, and at the same time, the blocking ring plate is pushed to slide upward in the cleaning frame, so that the first drain hole corresponds to the second drain hole. At this time, the clear water in the first chamber will enter the interior of the cleaning frame until the liquid level is higher than the planet carrier assembly, completing the cleaning by soaking in clear water.

[0020] 2. For an assembly device of a planet carrier assembly according to the present invention, when the circulation pump is started, the water in the second chamber is sent into the interior of the control ring to impact a plurality of blades in sequence, driving the rotating ring to rotate inside the control ring. The water flow impacting the blades can enter the inner cavity of the rotating ring and then into the interior of the connecting rod through the water leakage holes opened at the top of the rotating ring. A plurality of connecting rods spray around the planet carrier assembly to wash away the dirt lingering around the planet carrier assembly, reducing the spraying dead angle and improving the cleaning effect on the planet carrier assembly.

[0021] 3. For an assembly device of a planet carrier assembly according to the present invention, through the rotation of the rotating ring, a plurality of connecting rods drive the intermittent toothed plates to rotate and simultaneously mesh with a plurality of rotating gears, so that a plurality of winding rollers simultaneously wind the pull ropes to lift the planet carrier assembly on the floating net, enabling the blind area at the bottom to be cleaned by ultrasonic waves. And during the process of the planet carrier assembly floating up and down underwater, the water flow will pass through the pores of the planet carrier assembly from bottom to top to wash away the dirt that has been washed off. When the plurality of intermittent toothed plates are not meshed with the rotating gears, the planet carrier assembly drives the floating net to slide downward and reset under the action of gravity. By circulating the above steps, the cleaning effect on the planet carrier assembly can be further improved. Description of the Drawings

Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

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

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

[0034] Clear water is stored in both the first chamber 3४ and the second chamber 35, and the partition board 4 is provided to prevent the first chamber 34 and the second chamber 35 from communicating with each other

[0035] A cleaning frame 9 is provided on the partition plate 4. The cleaning frame 9 is located in the first chamber 34. A carrier table 18 for placing the planetary carrier assembly is slidably installed inside the cleaning frame 9. The outer wall of the carrier table 18 is attached to the inner wall of the cleaning frame 9. A lifting assembly is provided on the cleaning frame 9 for controlling the lifting or lowering of the carrier table 18 on the inner wall of the cleaning frame 9;

[0036] First, place the planetary carrier assembly to be cleaned on the carrier table 18, and then lower the carrier table 18 into the second chamber 35 through the provided lifting assembly. At this time, start the ultrasonic generator to clean the planetary carrier assembly. Moreover, the assembly table 2 is located on one side of the cleaning table 3. When the planetary carrier assembly is cleaned, it can be directly taken out for assembly, improving the assembly efficiency and reducing the secondary pollution suffered by the planetary carrier assembly during transportation.

[0037] A blocking ring plate 31 is slidably installed inside the cleaning frame 9. The outer wall of the blocking ring plate 31 is attached to the inside of the cleaning frame 9. A first drain hole 30 is provided on the cleaning frame 9, and a second drain hole 32 is provided on the blocking ring plate 31. By moving the blocking ring plate 31, the first drain hole 30 and the second drain hole 32 are made to correspond, so that the clean water inside the first chamber 34 enters the inside of the cleaning frame 9;

[0038] A convex block 33 is elastically installed on the blocking ring plate 31. One end of the convex block 33 extends into the cleaning frame 9. The top and bottom ends of the convex block 33 are both inclined.

[0039] After the carrier table 18 drives the planetary carrier assembly to perform ultrasonic cleaning in the second chamber 35 through the lifting assembly, then lift the carrier table 18 into the cleaning frame 9. At this time, the carrier table 18 will block the bottom of the cleaning frame 9. Moreover, when the carrier table 18 slides upward inside the cleaning frame 9, it will push the convex block 33 and drive the blocking ring plate 31 to slide upward inside the cleaning frame 9, making the first drain hole 30 and the second drain hole 32 correspond. At this time, the clean water in the first chamber 34 will enter the inside of the cleaning frame 9 through the first drain hole 30 and the second drain hole 32 until the liquid level is higher than the planetary carrier assembly, completing the soaking cleaning with clean water, and the impurities attached to the surface after ultrasonic cleaning can be rinsed, further improving the cleaning effect on the planetary carrier assembly.

[0040] A receiving ring 10 is provided on the cleaning frame 9. A water outlet pipe 11 is provided on the receiving ring 10. The other end of the water outlet pipe 11 penetrates through the partition plate 4 and extends into the second chamber 35.

[0041] After the cleaning is completed, the lifting assembly is used to control the sliding of the carrier table 18 inside the cleaning frame 9 again. As the carrier table 18 continues to slide upward, the inclined surface provided at the bottom of the bump 33 will be pressed, pushing the bump 33 into the inside of the blocking ring plate 31. Under the action of gravity, it will slide downward inside the cleaning frame 9, causing the first drain hole 30 and the second drain hole 32 to be misaligned, closing the channel for clean water in the first chamber 34 to enter the cleaning frame 9. During the upward sliding of the carrier table 18, the water inside the cleaning frame 9 will be pushed outwards and received by the provided receiving ring 10. At the same time, the sewage is re-sent into the second chamber 35 through the provided water outlet pipe 11 to complete the cycle, always keeping the water in the first chamber 34 clean.

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

[0043] A toothed ring 12 is rotatably installed inside the receiving ring 10. A transmission gear 14 meshing with the toothed 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 circular array inside the receiving ring 10 and all mesh with the toothed ring 12.

[0044] Only one of the winding rods 13 needs to be connected to the driving motor 16. With the cooperation of the toothed ring 12, multiple transmission gears 14 can be rotated simultaneously, driving multiple winding rods 13 to wind or unwind at the same time. When multiple winding rods 13 wind the connecting rope 15 at the same time, the carrier table 18 can be driven to slide upward inside the cleaning frame 9. When multiple winding rods 13 rotate to unwind the connecting rope 15, with the assistance of the weight of the planetary carrier assembly, the carrier table 18 can slide downward inside the cleaning frame 9.

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

[0046] When the driving motor 16 is started and the winding rod 13 is rotated, the control ring 17 will be pulled to move. Under the action of the multiple connecting rods 20, the control ring 17 will drive the carrier table 18 to move. And through the cooperation of the control ring 17, the multiple connecting rods 20, and the carrier table 18, the planetary carrier assembly can also be limited, effectively avoiding the offset of the planetary carrier assembly during cleaning.

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

[0048] A water leakage hole 28 is opened at the top end of the rotating ring 26. The connecting rod 20 is hollow. One end of the connecting rod 20 extends into the interior of the rotating ring 26, and a plurality of water spraying holes are opened on the connecting rod 20.

[0049] The impurities in the water in the second chamber 35 can be filtered by the arranged filter screen 6. When the circulating pump 5 is started, the water in the second chamber 35 is pumped out through the water inlet pipe 7 and sent into the interior of the control ring 17 through the drain pipe 8. Since one end of the drain pipe 8 is inclined towards the blades 27, the water flow discharged from the drain pipe 8 will sequentially impact the plurality of blades 27. At this time, under the impact of the water flow, the plurality of blades 27 will drive the rotating ring 26 to rotate inside the control ring 17. At the same time, the plurality of connecting rods 20 are fixedly connected to the rotating ring 26. Therefore, when the water flow flushes the blades 27 to make the rotating ring 26 rotate, it can drive the plurality of connecting rods 20 to rotate along the axis of the rotating ring 26. The water flow impacting the blades 27 can enter the inner cavity of the rotating ring 26 through the water leakage hole 28 opened at the top of the rotating ring 26 and enter the interior of the connecting rod 20, and finally be discharged towards the planet carrier assembly from the water spraying holes under the action of water pressure. When the planet carrier assembly is ultrasonically cleaned in the second chamber 35, the dirt surrounding the planet carrier assembly can be washed away, and the rotating ring 26 can drive the plurality of connecting rods 20 to spray around the planet carrier assembly, reducing the spraying dead angle and improving the cleaning effect on the planet carrier assembly.

[0050] As a preferred embodiment of the present invention, positioning blocks 25 are fixedly installed on the inner wall of the control ring 17. A floating net 19 is slidably installed on the bearing table 18. A winding roller 22 is rotatably installed on the bearing table 18. The top end of the floating net 19 is fixedly connected with a pull rope 29. The other end of the pull rope 29 passes through the positioning block 25 and is fixedly connected with the winding roller 22. A rotating gear 23 is fixedly installed on the winding roller 22. An intermittent toothed plate 24 meshing with the rotating gear 23 is fixedly installed on the rotating ring 21. A plurality of the pull rope 29, the winding roller 22, the rotating gear 23 and the intermittent toothed plate 24 are provided.

[0051] Multiple intermittent toothed plates 24 are simultaneously engaged or disengaged with multiple rotating gears 23. 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 sequentially impact multiple vanes 27, driving the rotating ring 26 to rotate inside the control ring 17. At the same time, multiple connecting rods 20 drive the rotating ring 21 to rotate on the bearing platform 18, and simultaneously drive the intermittent toothed plates 24 to rotate on the bearing platform 18. The multiple intermittent toothed plates 24 are simultaneously engaged with the multiple rotating gears 23, driving the multiple winding rollers 22 to simultaneously wind the pulling rope 29. At this time, the floating net 19 and the planet carrier assembly located on the floating net 19 can be lifted. After being lifted, the blind area where the planet carrier assembly fits against the bottom surface of the bearing platform 18 can be cleaned by ultrasonic waves. At the same time, the multiple connecting rods 20 can also perform all-round spraying on the planet carrier assembly. And during the process of the planet carrier assembly floating up and down underwater, the water flow will pass through the pores of the planet carrier assembly from bottom to top, washing away the dirt washed off. When the multiple intermittent toothed plates 24 are disengaged from the rotating gears 23, the planet carrier assembly, under the action of gravity, drives the floating net 19 to slide downward and reset. By cycling through the above steps, the cleaning effect on the planet carrier assembly can be further improved.

[0052] Working principle: When the driving motor 16 is started and the driving gear 14 controls the winding rod 13 to rotate under the action of the toothed ring 12, the bearing platform 18 carrying the planet carrier assembly is lowered into the interior of the second chamber 35 for ultrasonic cleaning. Subsequently, the bearing platform 18 is lifted into the interior of the cleaning frame 9. At this time, the bearing platform 18 will block the bottom of the cleaning frame 9. At the same time, it pushes the convex block 33 and drives the blocking ring plate 31 to slide upward inside the cleaning frame 9, making the first drain hole 30 correspond to the second drain hole 32. At this time, the clear water in the first chamber 34 will pass through the first drain hole 30 and the second drain hole 32 and enter the interior of the cleaning frame 9 until the liquid level is higher than the planet carrier assembly, completing the cleaning by soaking in clear water. The impurities attached to the surface after ultrasonic cleaning can be rinsed, further improving the cleaning effect on the planet carrier assembly.

[0053] Subsequently, the circulation pump 5 is started, the water in the second chamber 35 is pumped out through the water inlet pipe 7, and sent into the interior of the control ring 17 through the drain pipe 8, sequentially impacting multiple vanes 27, driving the rotating ring 26 to rotate inside the control ring 17. The water flow impacting the vanes 27 can enter the inner cavity of the rotating ring 26 and then enter the interior of the connecting rods 20 through the water leakage holes 28 opened at the top of the rotating ring 26. The multiple connecting rods 20 spray around the planet carrier assembly, washing away the dirt lingering around the planet carrier assembly, reducing the spraying dead angle, and improving the cleaning effect on the planet carrier assembly.

[0054] Meanwhile, when the water flow impacts on multiple blades 27 in sequence to drive the rotating ring 26 to rotate inside the control ring 17, multiple connecting rods 20 drive the rotating ring 21 to rotate on the bearing platform 18, and the intermittent toothed plates 24 also rotate on the bearing platform 18. When multiple intermittent toothed plates 24 are simultaneously engaged with multiple rotating gears 23, they will drive multiple winding rollers 22 to wind the pulling rope 29 at the same time. At this time, the floating net 19 and the planet carrier assembly located on the floating net 19 can be pulled up. After being pulled up, the blind area where the planet carrier assembly fits against the bottom surface of the bearing platform 18 can be cleaned by ultrasonic waves. At the same time, multiple connecting rods 20 can also spray the planet carrier assembly in all directions. And during the process of the planet carrier assembly floating up and down underwater, the water flow will pass through the pores of the planet carrier assembly from bottom to top to wash away the dirt that has been washed off. When multiple intermittent toothed plates 24 are no longer engaged with the rotating gears 23, the planet carrier assembly will drive the floating net 19 to slide downward and reset under the action of gravity. By repeating the above steps, the cleaning effect of the planet carrier assembly can be further improved.

Taking the observer's perspective as the standard, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
