Description

Technical Field

[0001] This invention belongs to the field of planetary gear riveting, and in particular relates to a riveting device for planetary gear processing. Background Technology

[0002] The planetary gear carrier includes an inner ring and an outer ring. The planetary gear body is supported and connected to the inner ring by rivets. A cover plate is inserted into the top of the rivets to cover the opening at the top of the outer ring. During the assembly of the planetary gear carrier, the ends of the rivets need to be riveted to limit the position of the cover. During the riveting process, the planetary gear carrier needs to be positioned on the table, and then the positioned planetary gear carrier is moved to the riveting station. However, during the positioning of the planetary gear carrier, it is not convenient to limit the outer and inner rings of the planetary gear carrier at multiple points, and to adjust the position of the rivets on the inner ring, which is not conducive to aligning and riveting the rivets.

[0015] Compared with the prior art, the riveting device for planetary gear machining described in this invention has the following advantages:

[0016] (1) The support body, clamping port, lifting body, inner clamping component and outer clamping component described in this invention realize the central clamping of the inner ring of the planetary gear carrier during the process of bringing the planetary gear carrier into the clamping port. Combined with the cooperation of the outer clamping component, it realizes multi-point clamping of the inner and outer rings of the planetary gear carrier, which helps to ensure that the planetary gear carrier is centrally positioned in the middle of the clamping port and ensures the stability of the planetary gear carrier.

[0017] When the rivet position is not ideal, the rotating seat can be rotated, and the electric cylinder, plug-in seat, plug-in slider and traction rod will rotate synchronously. The lifting body will rotate synchronously under the drive of the traction rod, which in turn will drive the inner clamping component to rotate. The inner clamping component will drive the inner ring of the planetary gear carrier to rotate, which will then drive the rivet to move until it is adjusted to the ideal riveting position. This allows the rivet position to be adjusted as needed after the planetary gear carrier is positioned, preparing for subsequent riveting.

[0018] (2) In the process of inserting the support body into the installation port, the insertion seat is pushed to the height to be installed, and then the support body is inserted into the installation port. During the process of inserting the support body into the installation port, the insertion slider will dock with the insertion seat to realize the installation of the support body. When the inner clamping component and the outer clamping component on the support body need to be maintained, the support body can be removed from the installation port, realizing the overall replaceability of the support body, the inner clamping component and the outer clamping component.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] To better understand the following embodiments, an explanation is provided: Figure 7 This is a first structural cross-sectional view of the support body 2 in an embodiment of the present invention, showing the state in which the planetary gear carrier 41 is to be installed; Figure 8 This is a second structural cross-sectional view of the support body 2 of a riveting device for planetary gear processing according to an embodiment of the present invention, showing the planetary gear carrier 41 positioned within the clamping opening 4.

[0040] like Figures 1 to 13As shown, in one embodiment, a riveting device for planetary gear processing includes a rotary table 1, a riveting assembly, multiple support bodies 2, multiple inner clamping assemblies, multiple outer clamping assemblies, and multiple rotary drive assemblies. The riveting assembly is disposed above the rotary table 1. Multiple mounting ports 3 are provided on the top edge of the rotary table 1. Multiple support bodies 2 are respectively inserted into the multiple mounting ports 3. Each of the multiple support bodies 2 has a clamping port 4 on its top. Multiple outer clamping assemblies are respectively disposed inside the multiple clamping ports 4. The outer clamping assemblies are used to clamp the outer ring body 4102 of the planetary gear carrier 41. Each of the multiple clamping ports 4 is provided with a lifting body 5. Multiple inner clamping assemblies are respectively disposed on the multiple lifting bodies 5. The inner clamping assemblies are used to clamp the inner ring body 4101 at the bottom end of the planetary gear carrier 41. Multiple rotary drive assemblies are respectively disposed at the bottom end of the mounting ports 3. The rotary drive assemblies are used to drive the lifting bodies 5 to rotate.

[0041] When the lifting body 5 moves to the top of the clamping port 4, the planetary gear frame 41 is placed on the top of the lifting body 5. The inner clamping component first clamps the inner ring 4101 at the bottom of the planetary gear frame 41, so that the rivet 4104 on the inner positioning ring is relatively fixed to the lifting body 5. Then, as the lifting body 5 moves into the clamping port 4, the outer clamping component clamps the outer ring 4102 of the planetary gear frame 41.

[0042] A support platform 6 is provided at the bottom of the rotary table 1, and a support shaft 7 is rotatably connected to the top of the support platform 6. The top end of the support shaft 7 is fixedly connected to the bottom of the rotary table 1. It should be understood that the rotary table 1 is rotatably mounted on the support platform 6 with the support of the support shaft 7.

[0043] A first motor 8 is fixedly mounted on the bottom of the support platform 6. A first drive gear 9 is fixedly connected to the output end of the first motor 8. A first follower gear 10 is fixedly connected to the bottom end of the support shaft 7. The first follower gear 10 meshes with the first drive gear 9. It should be understood that the first motor 8 drives the first drive gear 9 to rotate, the first drive gear 9 transmits the first follower gear 10, the first follower gear 10 drives the support shaft 7 to rotate, and the support shaft 7 drives the rotary table 1 to rotate, thereby realizing the rotation of the rotary table 1.

[0044] The external clamping assembly includes three connection ports 11, a top pressure seat 12, and a limiting ring 13. The three connection ports 11 are located on the inner wall of the clamping opening 4. A positioning frame 1101 is fixedly connected to the inner wall of each connection port 11. Two support pins 14 are fixedly connected inside the positioning frame 1101. Clamping claws 15 are slidably inserted into the surfaces of the two support pins 14. A second support spring 16 is sleeved on the surface of each of the two support pins 14. The two ends of the second support spring 16 are fixedly connected to the clamping claw 15 and the positioning frame 1101, respectively. The clamping claw 15... A first inclined groove 17 is provided on the surface, and a first linkage pin 18 is slidably arranged in the first inclined groove 17. A flipping frame 19 is fixedly connected to the end of the first linkage pin 18. The flipping frame 19 is rotatably connected to the inner wall of the positioning frame 1101. A plurality of support rods 20 are fixedly connected to the top of the top of the top pressure seat 12. The top of the plurality of support rods 20 is fixedly connected to the bottom of the lifting body 5. A pressure ring 21 is rotatably connected to the bottom of the top pressure seat 12. A limiting ring 13 is rotatably connected to the inner wall of the clamping port 4, and the limiting ring 13 is located below the lifting body 5. It should be understood that during the process of the lifting body 5 lowering its height, the lifting body 5 will support the planetary gear carrier 41 into the clamping port 4. The lifting body 5 drives the top pressure seat 12 to move downward through the support rod 20. The top pressure seat 12 drives the pressure ring 21 to press against the end of the flipping frame 19. While the flipping frame 19 flips, it drives the first linkage pin 18 to push the first inclined groove 17, and then pushes the clamping claw 15 to move until the clamping claw 15 clamps the surface of the outer ring 4102 of the planetary gear carrier 41, thus completing the clamping and fixing of the outer ring 4102 of the planetary gear carrier 41, and clamping the planetary gear carrier 41 in the center inside the clamping port 4.

[0045] The limiting ring 13 is used to limit the descent height of the lifting body 5, and after limiting the lifting body 5, it can provide movable support for the lifting body 5. When the lifting body 5 rotates, the limiting ring 13 can provide support while reducing the resistance to the rotation of the lifting body 5.

[0046] The inner clamping assembly includes an annular body 22, which is fixedly connected to the top of the lifting body 5. Insertion plates 23 are slidably inserted into both sides of the inner annular surface of the annular body 22. Second linkage pins 24 are fixedly connected to the ends of the two insertion plates 23 located inside the annular body 22. Arc-shaped clamping plates 25 are fixedly connected to the ends of the two insertion plates 23 after passing through the annular body 22. An adjusting column 26 is provided inside the annular body 22, and an adjusting plate 27 is fixedly connected to the top of the adjusting column 26. Two symmetrically arranged second inclined plates are formed on the surface of the adjusting plate 27. The groove 28, two second linkage pins 24 are respectively slidably set in the two second inclined grooves 28, the adjusting column 26 passes through the lifting body 5 and extends to the bottom of the lifting body 5, the bottom end of the adjusting column 26 is fixedly connected to the lifting body 5 with a first support spring 29, the first support spring 29 is sleeved on the surface of the adjusting column 26, the two ends of the first support spring 29 are respectively fixedly connected to the bottom end of the lifting body 5 and the adjusting column 26, the bottom of the adjusting column 26 is fixedly connected with a rubber block 30, and two top pressure rods 31 are fixedly connected to the bottom surface of the inner wall of the clamping port 4. It should be understood that during the installation of the planetary gear carrier 41, the inner ring 4101 of the planetary gear carrier 41 is inserted into the outside of the two arc-shaped clamping plates 25. Under the support of the first support spring 29, the two arc-shaped clamping plates 25 will initially clamp the inner ring 4101 of the planetary gear carrier 41.

[0047] As the lifting body 5 lowers, it synchronously drives the planetary gear frame 41 on the inner clamping assembly until the rubber block 30 at the bottom of the adjusting column 26 abuts against the two top pressure rods 31. During this process, the adjusting column 26 simultaneously supports the adjusting plate 27 and the second linkage pin 24, causing the second linkage pin 24 to abut against the second inclined groove 28. This, in turn, causes the two insertion plates 23 to be pressed together, supporting the arc-shaped clamping plate 25. Two arc-shaped clamping plates 25 clamp the inner ring 4101 of the planetary gear carrier 41, thus achieving centered clamping of the inner ring 4101 of the planetary gear carrier 41 during the process of bringing the planetary gear carrier 41 into the clamping port 4. Combined with the cooperation of the outer clamping component, multi-point clamping of the inner ring 4101 and outer ring 4102 of the planetary gear carrier 41 is achieved, which helps to ensure that the planetary gear carrier is centered in the middle position of the clamping port 4 and ensures the stability of the planetary gear carrier 41.

[0048] Specifically, the bottom of the top pressure seat 12 has holes for the two top pressure rods 31 to pass through.

[0049] The rotary drive assembly includes a rotary seat 32, which is rotatably connected to the bottom surface inside the mounting port 3. An electric cylinder 33 is fixedly inserted into the rotary seat 32. A connector 34 is fixedly connected to the top of the electric cylinder 33. A connector slider 35 is inserted into the connector 34. A traction rod 36 is fixedly connected to the top of the connector slider 35. The top of the traction rod 36 passes through the support body 2 and extends into the clamping port 4. The top of the traction rod 36 is fixedly connected to the bottom of the lifting body 5. A third support spring 56 is sleeved on the surface of the traction rod 36. Connecting rings 57 are fixedly connected to both ends of the third support spring 56. The connecting rings 57 are slidably connected to the bottom of the lifting body 5 and the clamping port 4. On the bottom of the inner wall of the opening 4, the bottom of the lifting body 5 and the bottom of the inner wall of the clamping opening 4 are both provided with annular grooves for connecting the connecting ring 57; it should be understood that during the process of inserting the support body 2 into the mounting opening 3, the insertion seat 34 is pushed to the height to be installed, and then the support body 2 is inserted into the mounting opening 3. During the process of inserting the support body 2 into the mounting opening 3, the insertion slider 35 will dock with the insertion seat 34, thereby realizing the installation of the support body 2. Furthermore, when the inner clamping component and the outer clamping component on the support body 2 need to be maintained, the support body 2 can be removed from the mounting opening 3, thereby realizing the overall replaceability of the support body 2, the inner clamping component and the outer clamping component;

[0050] When the rivet 4104 is not in the ideal position, the rotating seat 32 can be rotated, and the electric cylinder 33, the plug-in seat 34, the plug-in slider 35 and the traction rod 36 will rotate synchronously. The lifting body 5 will rotate synchronously under the drive of the traction rod 36, which in turn will drive the inner clamping component to rotate. The inner clamping component will drive the inner ring 4101 of the planetary gear carrier 41 to rotate, which will drive the rivet 4104 to move until it is adjusted to the ideal riveting position. This allows the position of the rivet 4104 to be adjusted as needed after the planetary gear carrier 41 is positioned, preparing for subsequent riveting.

[0051] The rotary drive assembly also includes a second motor 37. A rotating base 32 passes through the rotary table 1 and extends below it. A second follower gear 38 is fixedly connected to the surface of the rotating base 32. The second motor 37 is fixedly connected to the bottom of the rotary table 1. A second drive gear 40 is fixedly connected to the output end of the second motor 37, and the second drive gear 40 meshes with the second follower gear 38. It should be understood that when the position of the rivet 4104 needs to be adjusted, the second motor 37 is activated. The second motor 37 drives the second drive gear 40 to rotate, which synchronously transmits the second follower gear 38. The second follower gear 38 drives the rotating base 32 to rotate, thereby indirectly driving the lifting body 5 to rotate, adjusting the position of the rivet 4104 without manual adjustment by personnel.

[0052] It should be understood that the planetary gear carrier 41 includes an inner ring 4101 and an outer ring 4102. The planetary gear body 4105 is supported and connected to the inner ring 4101 by rivets 4104. A cover plate 4103 is inserted into the top of the rivets 4104 to cover the opening at the top of the outer ring 4102. During the assembly of the planetary gear carrier 41, the ends of the rivets 4104 need to be riveted to limit the cover. During the riveting process, the planetary gear carrier 41 needs to be positioned on the table, and then the positioned planetary gear carrier 41 is moved to the riveting station. However, during the positioning process, it is not convenient to limit the outer ring 4102 and the inner ring 4101 of the planetary gear carrier 41 at multiple points, and it is not convenient to adjust the position of the rivets 4104 on the inner ring 4101, making it difficult to align and rivet the rivets 4104. This embodiment can solve the above problems. The specific method is as follows:

[0053] Installation of planetary gear carrier 41: Insert the inner ring 4101 of the planetary gear carrier into the outside of the two arc-shaped clamping plates 25. Under the support of the first support spring 29, the two arc-shaped clamping plates 25 will initially clamp the inner ring 4101 of the planetary gear carrier 41.

[0054] Positioning of the planetary gear carrier 41: During the process of the lifting body 5 lowering its height, the lifting body 5 will support the planetary gear carrier 41 into the clamping port 4. The lifting body 5 drives the top pressure seat 12 to move downward through the support rod 20. The top pressure seat 12 drives the pressure ring 21 to press against the end of the flipping frame 19. While the flipping frame 19 flips, it drives the first linkage pin 18 to push the first inclined groove 17, and then pushes the clamping claw 15 to move until the clamping claw 15 clamps the surface of the outer ring body 4102 of the planetary gear carrier 41, thus completing the clamping and fixing of the outer ring body 4102 of the planetary gear carrier 41, and centered the planetary gear carrier 41 inside the clamping port 4.

[0055] During the descent of the lifting body 5, the lifting body 5 synchronously drives the planetary gear frame 41 through the internal clamping assembly until the rubber block 30 at the bottom of the adjusting column 26 abuts against the two top pressure rods 31. As the two top pressure rods 31 abut against the rubber block 30, the adjusting column 26 simultaneously supports the adjusting plate 27 and the second linkage pin 24, causing the second linkage pin 24 to abut against the second inclined groove 28. This, in turn, causes the two insertion plates 23 to be abutted, and the insertion plates 23 support the arc-shaped clamping plate 25, thus... An arc-shaped clamping plate 25 clamps the inner ring 4101 of the planetary gear carrier 41 tightly, achieving centered clamping of the inner ring 4101 of the planetary gear carrier 41 during the process of bringing the planetary gear carrier 41 into the clamping port 4. Combined with the cooperation of the outer clamping component, multi-point clamping of the inner ring 4101 and outer ring 4102 of the planetary gear carrier 41 is achieved, which helps to ensure that the planetary gear carrier 41 is centered in the middle position of the clamping port 4 and ensures the stability of the planetary gear carrier 41.

[0056] Adjustment of the position of rivet 4104: When the position of rivet 4104 is not ideal, the rotating seat 32 can be rotated, and the electric cylinder 33, the plug seat 34, the plug slider 35 and the traction rod 36 will rotate synchronously. The lifting body 5 will rotate synchronously under the drive of the traction rod 36, which in turn will drive the inner clamping component to rotate. The inner clamping component will drive the inner ring 4101 of the planetary gear carrier 41 to rotate, which will drive the rivet 4104 to move until it is adjusted to the ideal riveting position. This realizes that after the planetary gear carrier 41 is positioned, the position of rivet 4104 can be adjusted as needed to prepare for subsequent riveting.

[0057] like Figure 10 As shown, in one embodiment, the pressure ring 21 has an annular inclined surface 2101 along its edge, and the annular inclined surface 2101 of the pressure ring 21 contacts the top surface of the ends of the plurality of flipping frames 19. It should be understood that by providing the annular inclined surface 2101, an overlapping surface is provided between the pressure ring 21 and the flipping frame 19.

[0058] like Figure 1 , Figure 5 , Figure 6 and Figure 12 As shown, in one embodiment, a plug groove 42 is provided on the inner wall of the mounting port 3, a first plug body 43 is fixedly connected to both sides of the support body 2, a second plug body 44 is fixedly connected to the end of the support body 2, the first plug body 43 and the second plug body 44 are slidably inserted into the plug groove 42, an anti-detachment ring 45 is slidably sleeved on the outside of the rotating table 1, a limit groove 46 is provided at the end of the support table 6 away from the second plug body 44, the limit groove 46 is mounted on the anti-detachment ring 45, and a lifting adjustment device is provided at the bottom of the anti-detachment ring 45;

[0059] The lifting adjustment device includes three first cylinders 47, which are fixedly installed at the bottom of the support platform 6. The piston rods of the three first cylinders 47 pass through the support platform 6 and are fixedly connected to an annular slide rail 48. The anti-detachment ring 45 is slidably connected to the surface of the annular slide rail 48. It should be understood that by setting the first connector 43 and the second connector 44 to connect with the connector slot 42, the support body 2 is connected and joined in the mounting port 3, and the support body 2 is supported. During the riveting process, longitudinal support can be provided. After the support body 2 is installed, the three first cylinders 47 are activated. The three first cylinders 47 will push the annular slide rail 48 to rise. The annular slide rail 48 will drive the anti-detachment ring 45 to rise. The anti-detachment ring 45 will connect into the limiting groove 46 of the support body 2, thereby realizing the limiting of multiple support bodies 2. In the process of limiting the support body 2, the rotation of the rotary table 1 will drive the support body 2 to move. The anti-detachment ring 45 can move on the annular slide rail 48 to prevent obstruction of the rotation of the rotary table 1 and provide support for the edge of the rotary table 1.

[0060] like Figure 1 and Figure 2 As shown, in one embodiment, the riveting assembly includes a mounting bracket 49 located on the rear side of the rotary table 1. A second cylinder 50 is fixedly mounted on the top of the mounting bracket 49.

A plurality of riveting heads 52 are fixedly connected to the bottom of the riveting seat 51. Limiting rods 53 are fixedly connected to both ends of the top of the riveting seat 51. The limiting rods 53 pass through the mounting bracket 49 and extend to the top of the mounting bracket 49.

[0061] Specifically, the planetary gear carrier 41 includes an outer ring body 4102 and an inner ring body 4101. The inner ring body 4101 is rotatably connected to the bottom end inside the outer ring body 4102. Four rivets 4104 are fixedly connected to the top of the inner ring body 4101. Planetary gear bodies 4105 are fixedly sleeved on the surface of the rivets 4104. The multiple planetary gear bodies 4105 mesh with the teeth on the inner wall of the outer ring body 4102. A cover plate 4103 is inserted into the top of the multiple rivets 4104. The cover plate 4103 is in contact with the opening at the top of the outer ring body 4102.

[0062] Specifically, a monitoring frame 54 is fixedly connected to the top of the support platform 6. A CCD camera 55 is fixedly installed at the top of the monitoring frame 54. The CCD camera 55 is used to identify the position of the rivet 4104 on the planetary gear frame 41. When the position of the rivet 4104 is not appropriate, the peripheral controller 39 can determine the position of the rivet 4104 based on the image information captured by the CCD camera 55. When the position of the rivet 4104 is not appropriate, the rotary drive assembly is activated to drive the lifting body 5 to rotate. The lifting body 5 drives the inner ring 4101 to rotate through the inner clamping assembly, thereby driving the rivet 4104 to move. When the position of the rivet 4104 in the image information captured by the CCD camera 55 is appropriate, the controller 39 controls the rotary drive assembly to stop driving, preparing for the precise riveting of multiple riveting heads 52.

[0063] Specifically, a battery module 58 is installed at the bottom of the rotary table 1, which is used to supply power to the electric cylinder 33.
