AI Technical Summary
During the sealing process of the shock absorber, the inner wall of the cylindrical workpiece is easily deformed by the external extrusion, which can cause the oil seal to twist, the lip to shift, and the skeleton to shift, thus damaging the sealing structure and posing a risk of leakage and premature failure.
The sealing machine employs a low-tension vibration damper. By setting two sets of separating components within the sealing mechanism to form a ring structure, the separating rod is placed between the workpiece sealing area and the oil seal. In conjunction with the servo drive structure, it avoids direct compression of the oil seal by the inner wall of the workpiece. Furthermore, through multiple radial contractions and lifts, it ensures the smooth progress of the sealing process.
It effectively protects the sealing integrity of the oil seal, avoids oil seal deformation and damage to the sealing structure, improves sealing processing efficiency, and ensures the sealing performance and service life of the shock absorber.

Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of vibration damper processing equipment, specifically relating to a low-tension vibration damper sealing machine. Background Technology
[0002] Riveting machines are key equipment for closing, sealing, and forming the ends of cylindrical workpieces. They are widely used in the sealing processing of thin-walled long cylindrical workpieces such as shock absorbers, pipe fittings, and bushings. Traditional riveting equipment mainly uses the high-speed rotation of the riveting head to apply continuous extrusion to the ends of cylindrical workpieces, causing the metal to undergo plastic deformation to achieve the forming purpose.
[0003] The core operation of the shock absorber port sealing process is as follows: the excess material at the end of the cylindrical workpiece that exceeds the oil seal installation position is circumferentially bent and flanged so that the bent part of the cylinder is horizontally pressed against the upper end face of the oil seal. The oil seal is fixed by the clamping force of the metal flange, and the compression sealing structure is fixed to ensure the sealing of the hydraulic oil inside the shock absorber and prevent oil leakage failure during use.
[0004] In the actual sealing process, the cylindrical workpiece and the oil seal are in a tightly fitted assembly state, with no extra clearance for the oil seal. The bending area at the end of the cylindrical workpiece needs to undergo a large-scale plastic deformation, gradually bending and flipping from a vertical cylindrical wall to a horizontal pressing structure. At the same time, the riveting and extrusion mechanism only acts on the outer side of the cylindrical workpiece, and cannot constrain or limit the deformation trajectory and inner contour of the inner wall of the cylindrical workpiece.
[0005] During the deformation process of the port being gradually bent and folded, the inner wall of the cylindrical workpiece undergoes angular deflection and displacement synchronously with the outer extrusion. The inner wall edge will directly contact and continuously extrude the outer edge area of the upper surface of the oil seal. Due to the uneven force and local stress concentration during the deformation process, it is very easy to cause the oil seal edge to be squeezed and deformed, the lip to be twisted, and the skeleton to be offset, thereby damaging the original sealing structure of the oil seal and creating quality hazards such as leakage and early failure of the shock absorber. Summary of the Invention

Detailed Implementation
[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0033] Example 1
[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 10As shown, a low-tension vibration damper sealing machine includes a sealing machine body 1, a second lead screw drive assembly 3 disposed on its top, and a first servo drive assembly 4 fixedly installed on the slider of the second lead screw drive assembly 3. The first lead screw drive assembly 2 is fixedly installed on the upper surface of the sealing machine body 1, and the first lead screw drive assembly 2 is located below the first servo drive assembly 4. The output end of the first servo drive assembly 4 is fixedly connected to a sealing mechanism 5. The sealing mechanism 5 includes a turntable 51, a separator block 52, and a rolling head 53. The top of the separator block 52 is fixedly connected to the output end of the first servo drive assembly 4. The turntable 51 is fixedly connected to the separator block 52. The rolling head 53 is fixedly installed on the inner side of the turntable 51. Two sets of separator assemblies are provided on the inner side of the turntable 51. The two sets of separator assemblies are spliced to form a ring structure, and a gap is left between the two sets of separator assemblies. Each set of separator assemblies includes multiple separator rods 54, and the multiple separator rods 54 are evenly distributed. The rolling head 53 is used for sealing, and the separator rods 54 are used to pad between the sealing part and the oil seal when sealing.
[0035] It should be noted that, as the operating platform, the sealing machine body 1 has the damper to be sealed vertically mounted on the slider of the first lead screw drive assembly 2 during operation. A clamp is installed on the slider of the first lead screw drive assembly 2 to fix the damper as needed. After the damper is deployed, the second lead screw drive assembly 3 drives the first servo drive assembly 4 downwards, pushing the sealing mechanism 5 to the sealing area of the damper. The second lead screw drive assembly 3 then stops operating, and the first servo drive assembly 4 drives the sealing mechanism 5 to rotate at a constant speed. The rolling head 53 applies continuous pressure to the end of the cylindrical workpiece, causing plastic deformation of the metal to achieve the forming purpose. During the rotation of the sealing mechanism 5, the second lead screw drive assembly 3 continues to slowly push the first servo drive assembly 4 downwards, thereby ensuring that the rolling head 53 and the cylindrical workpiece remain in contact. The workpiece port remains in contact, enabling low-tension, non-destructive sealing of the shock absorber. While the roller head 53 continuously presses the cylindrical workpiece port, the separator rod 54, forming an annular structure, adheres to the edge of the upper surface of the oil seal. The edge of the separator rod 54 contacts the inner wall of the cylindrical workpiece port. During the continuous pressing of the cylindrical workpiece port by the roller head 53, the separator rod 54 acts as a pad for the pressing part. The specific number of separator rods 54 is an odd number, such as 5, so that the bent part of the cylindrical workpiece port is located at the edge of the upper surface of the separator rod 54, completely higher than the upper surface of the oil seal. At this time, when the cylindrical workpiece port is pressed, the bent part will not compress the internal oil seal, thereby avoiding the problems of oil seal edge extrusion deformation, lip twisting, and skeleton displacement, and thus there is no damage to the original sealing structure of the oil seal.
[0036] Example 2
[0037] like Figure 3 , Figure 7 , Figure 8 and Figure 11 As shown, a guide rod 55 is integrally formed on the inner side of the separator rod 54, and a driven rod 511 is integrally formed on the upper surface of the guide rod 55. The driven rod 511 is perpendicular to the guide rod 55. A first retraction mechanism 56 is slidably connected to the guide rod 55 corresponding to a set of separator components. The first retraction mechanism 56 includes a positioning cylinder 561. A bearing plate 563 is integrally formed on the bottom of the positioning cylinder 561. The bearing plate 563 is arranged radially along the positioning cylinder 561. Multiple bearing plates 563 are arranged at equal intervals, and the bearing plate 563 is connected to the guide rod 54. The guide rod 55 is slidably connected, and the first gear 565 is sleeved on the outer wall of the positioning cylinder 561. The first gear 565 is located above the bearing plate 563. The driven rod 511 is slidably connected to the first gear 565. A first arc-shaped hole 566 is opened at the junction of the first gear 565 and the driven rod 511. A movable block 58 is slidably connected to the inner side of the turntable 51. A second servo drive assembly 564 is fixedly installed inside the movable block 58. The gear at the output end of the second servo drive assembly 564 meshes with the first gear 565.
[0038] It should be noted that the shape of the separator rod 54 in both sets of separator components is exactly the same. One set of separator components is controlled by the first retraction mechanism 56, which is used to adjust the position of the separator rod 54. During operation, the second servo drive component 564 engages with the first gear 565 via a gear. During the rotation of the first gear 565, the driven rod 511 is forced to move radially using the first arc-shaped hole 566. The direction of movement of the driven rod 511 varies depending on the rotation direction of the first gear 565. Figure 8 As shown, when the first gear 565 rotates counterclockwise, the driven rod 511 moves towards the center of the cylindrical workpiece. When the first gear 565 rotates clockwise, the driven rod 511 moves towards the cylindrical wall of the cylindrical workpiece. During the movement of the driven rod 511, it drives the partition rod 54 through the guide rod 55. When the driven rod 511 moves towards the inner wall of the cylindrical workpiece, the partition rod 54 will eventually fit against the inner wall of the cylindrical workpiece. When the driven rod 511 moves towards the center of the cylindrical workpiece, the partition rod 54 will move away from the inner wall of the cylindrical workpiece, ensuring that the diameter of the partition rod 54 at the port of the cylindrical workpiece is within acceptable limits. After shrinking, it can detach from the oil seal. The bearing plate 563 at the bottom of the positioning cylinder 561 is slidably connected to the guide rod 55 to determine the direction of movement of the guide rod 55, so as to ensure that the two sets of separation components can be spliced into a complete ring structure without misalignment. The positioning cylinder 561 is used to determine the position of the first gear 565, and at the same time, it also seals one end of the first arc-shaped hole 566 to prevent the driven rod 511 from detaching from the first arc-shaped hole 566. Furthermore, the axis of the positioning cylinder 561 coincides with the axis of the turntable 51, ensuring that the separation rod 54 can be completely fitted with the inner wall of the cylindrical workpiece.
[0039] Example 3
[0040] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 11 As shown, since the two sets of separating components are on the same horizontal plane and the length of each separating rod 54 is fixed, if all the separating rods 54 move toward the center of the cylindrical workpiece at the same time, they will obstruct each other, thus preventing the separating rods 54 from leaving the inner wall of the cylindrical workpiece. In order to prevent the two sets of separating components from obstructing each other and to allow the two sets of separating components to move toward the center of the cylindrical workpiece in stages, this application further provides the following technical solution.
[0041] Another set of partition components has a guide rod 55 slidably connected to a second retraction mechanism 57. The second retraction mechanism 57 includes a support frame 571, which is slidably connected to the guide rod 55. The support frame 571 is sleeved on the top of the combination of the positioning cylinder 561 and the bearing plate 563. The bottom of the support frame 571 has equally spaced receiving grooves 576. The top of the inner side of the support frame 571 is rotatably mounted with a second gear 574. The second gear 574 is slidably connected to the driven rod 511. A second arc-shaped hole 575 is opened at the junction of the second gear 574 and the driven rod 511. The inner side of the turntable 51 is slidably connected to a movable block 58. A third servo drive assembly 573 is fixedly installed inside the movable block 58. The gear at the output end of the third servo drive assembly 573 meshes with the second gear 574.
[0042] It should be noted that after the first shrinking mechanism 56 adjusts the position of one set of separating components, the second shrinking mechanism 57 adjusts another set of separating components. The second shrinking mechanism 57 operates on the same principle as the first shrinking mechanism 56. During its operation, the third servo drive component 573 engages with the second gear 574 through gear meshing. During the rotation of the second gear 574, it pushes the driven rod 511 through the second arc-shaped hole 575. Depending on the rotation direction of the second gear 574, the movement direction of the driven rod 511 is also different. When the second gear 574 rotates clockwise, the driven rod 511 drives the separating rod 54 to move towards the cylindrical wall of the cylindrical workpiece through the guide rod 55. When the second gear 574 rotates counterclockwise, the driven rod 511 drives the separating rod 54 to move towards the center of the cylindrical workpiece through the guide rod 55. The sliding fit between the support frame 571 and the guide rod 55 can determine the movement direction of the separating rod 54 corresponding to the second shrinking mechanism 57. The receiving groove 576 at the bottom of the support frame 571 is used to receive the guide rod 55 corresponding to the first shrinking mechanism 56.
[0043] Furthermore, such as Figure 4 and Figure 5As shown, during the continuous pressing of the cylindrical workpiece port by the roller head 53, the partition rod 54 plays a role in changing the bending part of the cylindrical workpiece, making the bending part higher than the upper surface of the oil seal. The roller head 53 can only continuously press the edge of the cylindrical workpiece port, and cannot press the part of the bent cylindrical workpiece port facing the center of the damper onto the upper surface of the oil seal. In order to process the cylindrical workpiece port close to the center of the damper, this application further provides the following technical solution.
[0044] A linear telescopic component is fixedly installed inside the partition block 52. The top of the movable block 58 is connected to the linear telescopic component inside the partition block 52. An anti-detachment protrusion 59 is integrally formed on the edge of the movable block 58. A guide groove 510 is provided at the junction of the inner side of the turntable 51 and the anti-detachment protrusion 59. A linear telescopic component is fixedly installed inside the movable block 58. A partition frame 572 is fixedly connected to the output end of the linear telescopic component. The bottom of the partition frame 572 is fixedly connected to the top of the support frame 571. The rotating rod of the second servo drive component 564 passes through the second gear 574. A third arc-shaped hole 577 is provided at the junction of the second gear 574 and the rotating shaft of the second servo drive component 564. A support plate 562 is integrally formed on the outer wall of the positioning cylinder 561. The gear at the output end of the third servo drive component 573 is rotatably mounted on the upper surface of the support plate 562.
[0045] It should be noted that the support plate 562 is used to determine the position of the third servo drive component 573 and to separate the second gear 574 and the first gear 565. Furthermore, the presence of the third arc-shaped hole 577 ensures that the rotation of the second gear 574 is not obstructed by the rotating rod of the second servo drive component 564. Both the linear telescopic component inside the separator block 52 and the linear telescopic component inside the movable block 58 are electric cylinders. The electric cylinder inside the separator block 52 is used to drive the movable block 58 to move up and down, thereby controlling the height of the two sets of separator components. The first retraction mechanism 56 and the second retraction mechanism 57 respectively... After the corresponding separating components are adjusted, the electric cylinder drives the movable block 58 to move upward, taking the two sets of separating components away from the oil seal. The operation of the first shrinkage mechanism 56 and the second shrinkage mechanism 57 allows the separating rod 54 to smoothly detach from the oil seal after the workpiece port diameter shrinks. The anti-detachment protrusion 59 set at the edge of the movable block 58 slides in cooperation with the guide groove 510 on the inner side wall of the turntable 51 to determine the movement path of the movable block 58. The top of the positioning cylinder 561 is fixedly connected to the movable block 58. After both sets of separating components have left the oil seal, the electric cylinder inside the movable block 58 drives the separating frame 572 upward, taking the second shrinkage mechanism away from the oil seal. Mechanism 57 and its corresponding separator 54 move upward away from the first retraction mechanism 56 and its corresponding separator 54. Then, the third servo drive assembly 573 engages with the second gear 574 through gear meshing, pushing a set of separator components toward the inner wall of the cylindrical workpiece again. However, this time the second gear 574 only rotates a small angle, only needing to ensure that the separator 54 moves to the vicinity of the port of the cylindrical workpiece at this time. Subsequently, the electric cylinder in the separator block 52 pushes the movable block 58 downward. During this process, the separator 54 corresponding to the second retraction mechanism 57 will press down on the entire port of the cylindrical workpiece, pressing the port of the cylindrical workpiece toward the oil seal. When the end of the cylindrical workpiece bends downward toward the oil seal, the second servo drive component 564 operates, pushing the partition rod 54 corresponding to the first shrinking mechanism 56 toward the barrel wall of the cylindrical workpiece, squeezing the end of the cylindrical workpiece, and achieving excessive deformation by expanding the inward shrinkage angle of the end. Then, the first shrinking mechanism 56 drives the partition rod 54 away from the end of the cylindrical workpiece, allowing the end of the cylindrical workpiece to spring back in advance. Finally, the partition rod 54 corresponding to the second shrinking mechanism 57 presses the entire end of the cylindrical workpiece into contact with the oil seal, thereby avoiding the situation where the end of the cylindrical workpiece springs back and causes the seal to fail.
[0046] Working principle of the invention:
[0047] The vibration damper to be sealed is placed vertically on the slider of the first lead screw drive assembly 2 and fixed by a clamp. The first lead screw drive assembly 2 transports the vibration damper to the bottom of the sealing mechanism 5. Then, the second lead screw drive assembly 3 drives the first servo drive assembly 4 and the entire sealing mechanism 5 to move downward to the area of the vibration damper to be sealed. Then, the first servo drive assembly 4 drives the sealing mechanism 5 to rotate at a uniform speed. During this process, the second lead screw drive assembly 3 drives the first servo drive assembly 4 to move downward slowly, so that the rolling head 53 continuously squeezes the port of the cylindrical workpiece of the vibration damper, causing the metal to undergo plastic deformation and achieve the initial sealing of the port.
[0048] When the roller head 53 presses the cylindrical workpiece, the two sets of partition components on the inner side of the turntable 51 are spliced into a complete ring. The partition rod 54 is placed between the workpiece sealing part and the oil seal. The partition rod 54 fits against the edge of the upper surface of the oil seal and contacts the inner wall of the workpiece port, raising the bent part of the workpiece port above the upper surface of the oil seal. This avoids the cylindrical workpiece pressing the oil seal during the roller bending process, prevents the oil seal edge from deforming, the lip from twisting, and the skeleton from shifting, and protects the original sealing structure of the oil seal.
[0049] After the initial bending of the end of the cylindrical workpiece, the second servo drive assembly 564 drives the first gear 565 to rotate via gear meshing. This drives the driven rod 511, guide rod 55, and separator rod 54 to move radially through the first arc-shaped hole 566, causing one set of separator components to leave the inner wall of the cylindrical workpiece. Subsequently, the third servo drive assembly 573 meshes with and drives the second gear 574, which then carries the other set of separator components away from the inner wall of the cylindrical workpiece through the second arc-shaped hole 575. Then, the piston rod of the electric cylinder inside the separator block 52 retracts, driving the movable block 58 upward, thereby completely removing both sets of separator components from the upper surface of the oil seal.
[0050] The electric cylinder inside the movable block 58 drives the separating frame 572 upward, pulling the second shrinking mechanism 57 and its corresponding separating rod 54 upward away from the first shrinking mechanism 56 and its corresponding separating rod 54. Then, the third servo drive assembly 573 slightly drives the second gear 574, causing the separating rod 54 to move above the shrunken workpiece port. The electric cylinder inside the separating block 52 then pushes the movable block 58 downward. During this process, the separating rod 54 corresponding to the second shrinking mechanism 57 presses down on the entire port of the cylindrical workpiece, pressing the port of the cylindrical workpiece towards the oil seal. When the port of the cylindrical workpiece bends downward towards the oil seal, the second... The servo drive assembly 564 operates, pushing the separator rod 54 corresponding to the first shrinking mechanism 56 to squeeze the port of the cylindrical workpiece. Excessive deformation is achieved by expanding the inward shrinkage angle of the port. Then, the first shrinking mechanism 56 drives the separator rod 54 away from the port of the cylindrical workpiece, allowing the port of the cylindrical workpiece to spring back in advance. Finally, the separator rod 54 corresponding to the second shrinking mechanism 57 presses the entire port of the cylindrical workpiece into contact with the oil seal. As the turntable 51 continues to rotate, the separator rod 54 corresponding to the second shrinking mechanism 57 can press the port of the cylindrical workpiece into contact with the surface of the oil seal, thus completing the low-tension non-destructive sealing operation of the vibration damper.
[0051] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
