Description

Technical Field

[0001] The present application relates to the technical field of hydraulic bushing forming equipment, and particularly to a bending device for vehicle hydraulic bushings. Background Art

[0002] A hydraulic bushing is a vibration control component that combines an elastomer and a liquid, and is widely used in fields such as automobiles and construction machinery. It adjusts damping and stiffness through liquid flow, improving the vibration damping performance and comfort of the system;

[0003] A hydraulic bushing usually consists of a metal inner tube, a rubber main spring, a skeleton, a nylon limit block, a metal outer tube, and internal liquid (such as ethylene glycol). The rubber main spring divides the cavity filled with liquid into two liquid chambers, which are connected by a narrow flow channel (inertia channel);

[0004] When a hydraulic bushing is subjected to an external force, the liquid flows between the two liquid chambers, forming a resonance system. The flow of the liquid generates a damping force, which can effectively absorb and consume vibration energy. The resonance frequency of the hydraulic bushing can be changed by adjusting the size of the liquid cavity, the shape of the flow channel, or the filling amount of the liquid to meet different vibration frequency requirements. The hydraulic bushing can reach a very high damping force at a specific frequency, providing excellent vibration control effects;

[0005] During the production process of hydraulic bushings, in order to lock the hydraulic bushing with the outer shell and prevent the lateral force during vehicle driving from causing the hydraulic bushing to break away from the outer shell and ensure driving safety, a bending device is needed to lock the hydraulic bushing with the outer shell;

[0006] However, in the prior art, 60-degree tooling friction-guided bending is usually adopted. This design easily deforms the middle skeleton of the hydraulic bushing. At the same time, the above-mentioned bending method requires two processes, first guiding and then bending, with too high manufacturing costs and too low production capacity. Moreover, friction bending easily damages the rubber covering the surface of the hydraulic bushing, resulting in rusting after installation. Therefore, it is necessary to provide a bending device for vehicle hydraulic bushings to solve the above problems.

[0007] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0044] Embodiment 1:

[0045] This embodiment mainly elaborates on the specific structure of a vehicle hydraulic bushing (hereinafter referred to as the bushing), as well as the structure and working principle of a bending device for bending the bushing. Specifically:

[0046] Figure 3 - Figure 4 Shown is the bushing 5 to be bent in the present application. This bushing 5 is a hydraulic bushing, which is a front lower control arm bushing of a certain passenger car designed with a hydraulic structure. This product has high damping characteristics and can greatly attenuate the low-frequency large-amplitude vibrations of the whole vehicle;

[0047] This bushing 5 includes an inner core 55. This inner core 55 is the innermost ring structure of this bushing 5 and has a through hole 551, which is used as a positioning hole during subsequent bending processing;

[0048] A rubber 52 is integrally vulcanized on the outer ring of the inner core 55. At the same time, a skeleton 54 is also arranged inside the rubber 52. This skeleton 54 is used to support the rubber 52 to maintain the strength of the rubber 52;

[0049] At the same time, an outer spring 53 is arranged on the outer ring of the rubber 52. A liquid-filled flow channel 521 is formed between the outer spring 53 and the rubber 52. Thus, when the outer spring 53 and the rubber 52 are assembled, liquid is filled in the flow channel 521, and then a bushing assembly is formed;

[0050] After the bushing 5 is assembled, in order to protect the bushing 5, an outer sleeve 51 is provided on the outer circumference of the bushing 5. At the same time, a locking claw 522 is provided on the bushing 5. The locking claw 522 is used to lock the bushing 5 and the outer sleeve 51, preventing the lateral force during the vehicle's driving from causing the bushing 5 to break away due to no outer shell and ensuring driving safety;

[0051] It can be understood that the bending process refers to the operation process of clamping the bushing 5 and the outer sleeve 51 tightly through the locking claw 522. In the initial state, the locking claw 522 is parallel to the axis of the bushing 5. After bending, the locking claw 522 turns outwards and clamps on the outer sleeve 51 (refer to the state of Figure 4 ). In this application, six groups of locking claws 522 are arranged along the circumferential direction. The six groups of locking claws 522 are bent in sequence to tightly fix the outer sleeve 51;

[0052] In order to perform the above bending operation, as Figure 1 - Figure 2 shown, the bending equipment of the bushing 5 is shown. The bending equipment includes a clamping mechanism 2. The clamping mechanism 2 is used to clamp and fix the combination of the bushing 5 and the outer sleeve 51 when bending the locking claw 522;

[0053] The clamping mechanism 2 includes a base 1 and a lifting seat 21 that can slide vertically on the base 1. The lifting seat 21 can be driven by an electric cylinder. It can be understood that a slideway (not shown in the figure) matching the lifting seat 21 is provided on the base 1. The slideway is used to guide the movement of the lifting seat 21 so that the lifting seat 21 moves vertically back and forth more stably;

[0054] As Figure 5 - Figure 6 shown, a connecting shaft 29 is installed on the lifting seat 21 by a bearing. It should be noted that a servo system (not shown in the figure) is provided inside the lifting seat 21. The output end of the servo system is connected to the connecting shaft 29. Thus, through the servo system, the rotation angle of the connecting shaft 29 can be accurately controlled;

[0055] At the same time, a tooling seat 210 is fixedly installed at the upper end of the connecting shaft 29. A counterbore (not marked in the figure) adapted to the inner core 55 of the bushing 5 is provided inside the tooling seat 210, and a lower jacking shaft 211 is provided inside the counterbore. Thus, when positioning the lower end of the bushing 5, the outer circumference of the inner core 55 is restricted through the counterbore, and the lower jacking shaft 211 is jacked into the lower end of the through hole 551;

[0056] In order to position the upper end of the bushing 5, a shaft seat 24 is fixedly installed on the base 1. The upper jacking shaft 241 is fixedly or rotatably provided at the lower end of the shaft seat 24. The upper jacking shaft 241 is adapted to be inserted into the upper end of the through hole 551 and limit the bushing 5;

[0057] As Figure 1 - Figure 2As shown, a calibrator 27 is provided on the shaft seat 24. The calibrator 27 can be an optoelectronic sensor to calibrate the position where the bushing 5 needs to be bent;

[0058] To bend the locking claw 522, as Figure 9 - Figure 10 shown, a bending mechanism 4 is provided on the base 1. The bending mechanism 4 includes a cylinder seat 41 fixedly installed on the base 1, and a cylinder 42 is hinged on the cylinder seat 41;

[0059] Combined with Figure 1 - Figure 2 , the clamping mechanism 2 and the bending mechanism 4 are respectively arranged on both sides of the base 1. At the same time, a window 11 is provided on the base 1, so that the cylinder 42 can extend through the window 11 to the position where the bushing 5 is clamped;

[0060] At the same time, a side vertical plate 25 is fixedly installed at the lower end of the shaft seat 24, and a rotating seat 43 is hinged to the output end of the cylinder 42. Pin shafts 26 are arranged on both sides of the rotating seat 43, and the pin shafts 26 are installed on the side vertical plate 25 by bearings. Thus, when the cylinder 42 expands and contracts, the rotating seat 43 can rotate on the side vertical plate 25;

[0061] Continue to refer to Figure 9 - Figure 10 , a bending seat 44 is fixedly installed on the rotating seat 43, and a pressing head 45 is fixedly installed on the bending seat 44. The pressing head 45 is adapted to the locking claw 522 and can perform a bending action on a single locking claw 522;

[0062] To prevent the bushing 5 from always remaining locked when being bent, as Figure 5 - Figure 6 shown, a coupling 28 is sleeved outside the connecting shaft 29, and a locking rod 23 is fixedly installed on the coupling 28. The locking rod 23 is adapted to rotate with the coupling 28;

[0063] At the same time, a stopper 22 is fixedly installed on the base 1. The stopper 22 has a locking table 221 adapted to the locking rod 23. Thus, when the bushing 5 is bent, the locking rod 23 can rotate into the locking table 221, and then the lower end of the locking rod 23 abuts against the upper end of the locking table 221 to prevent the bushing 5 from moving in the vertical direction, and further keep the bushing 5 locked when being bent;

[0064] More preferably, an inclined surface 222 is provided on the stopper 22 to facilitate the locking rod 23 to enter and exit the locking table 221 conveniently;

[0065] In this embodiment, the rotation of the coupling 28 can be manually controlled or controlled by a servo motor, which is not limited here;

[0066] More preferably, a PLC control system is also provided in this application to facilitate the coordinated operation control of each electrical component;

[0067] In summary, after the bushing 5 is filled with liquid, the bushing 5 is placed in the tooling seat 210. At this time, according to the characteristics of the bushing 5, a foolproof pin is provided in the tooling seat 210 to ensure the correct placement position of the bushing 5;

[0068] At this time, the lower jacking shaft 211 abuts against the lower end of the through hole 551. Subsequently, the bending equipment is started, the jacking seat 21 is lifted, and the bushing 5 is locked by the lower jacking shaft 211 and the upper jacking shaft 241. At the same time, the locking rod 23 enters the locking table 221 of the stopper 22 to ensure that the bushing 5 always remains in a locked state during bending (to ensure safety and control the defective rate). After the bushing 5 is locked, after the bending equipment self-inspects that all positions are correct, the air cylinder 42 starts to drive the pressure head 45 to move. The pressure head 45 always fits on the surface to be bent and performs a point arc movement. Calculate the piston travel distance of the air cylinder 42 to make the pressure head 45 perform an arc movement of 90 degrees (the piston stroke limit of the air cylinder can be adjusted to meet different angle bends);

[0069] After bending, the air cylinder 42 returns to its original position, and the servo motor drives the tooling seat 210 to rotate, rotates to the next position to be bent and locks it. This is repeated until all six locking claws 522 to be bent are completed. Subsequently, the locking rod 23 is loosened, the jacking seat 21 descends, the product is disengaged from the locked state, the bushing 5 is manually taken out, and the next bushing 5 is loaded to complete the next cycle.

[0070] Embodiment 2:

[0071] During the clamping and relaxation process of the bushing 5, since positioning and clamping are performed through the lower jacking shaft 211 and the upper jacking shaft 241, during the bending process, the bushing 5 will adhere to the lower jacking shaft 211, resulting in difficult material removal of the bushing 5;

[0072] To solve the above problems, as Figure 1 and Figure 6 - Figure 7 shown, a lifting mechanism 3 is provided on the jacking seat 21. The lifting mechanism 3 is used to lift and position the bushing 5 during the clamping process of the bushing 5. The lifting mechanism 3 includes a first rack 33 fixedly installed on the top of the jacking seat 21, and the first rack 33 can move vertically synchronously with the jacking seat 21;

[0073] At the same time, two groups of bearing seats 31 are fixedly installed on the base 1, a rotating shaft 32 is installed between the two groups of bearing seats 31, and a first gear 34 is fixedly installed on the rotating shaft 32. The first gear 34 meshes with the first rack 33. Thus, when the first rack 33 moves vertically, it can drive the first gear 34 to move synchronously, and then drive the rotating shaft 32 to rotate;

[0074] As Figure 6 - Figure 7As shown in the figure, a discharging mechanism 6 is arranged on one side of the rotating shaft 32. The discharging mechanism 6 is used to remove the bushing 5 from the clamped state after bending. The discharging mechanism 6 includes a second gear 67 fixedly installed on the rotating shaft 32, and the second gear 67 is adapted to rotate synchronously with the rotating shaft 32;

[0075] Meanwhile, a vertical slide rail 63 is fixedly installed on the base 1. A slider 64 is slidably arranged on the slide rail 63. A toothed plate 65 is fixedly installed on the slider 64. A second rack 68 is arranged on the toothed plate 65, and the second rack 68 meshes with the second gear 67. Thus, when the second gear 67 rotates, it can drive the toothed plate 65 to slide in the vertical direction;

[0076] And a support ring 35 is fixedly installed at the upper end of the toothed plate 65. The support ring 35 is adapted to the outer sleeve 51 of the bushing 5, and the inner diameter of the support ring 35 is greater than the outer diameter of the tooling seat 210. Therefore, the tooling seat 210 can pass through the support ring 35 without obstruction.

[0077] Combined with Figure 4 It can be understood that the lower end of the outer sleeve 51 has a flange 511. The flange 511 can be placed on the upper end of the support ring 35. At the same time, a positioning hole 512 is arranged on the flange 511, and the positioning hole 512 can be used as a positioning reference during the bending process;

[0078] Such as Figure 7 As shown in the figure, a limit post 36 is fixedly installed at the upper end of the support ring 35. The limit post 36 cooperates with the positioning hole 512 to position the bushing 5. At the same time, an internal thread (not shown in the figure) is arranged at the upper end of the limit post 36, and an arc-shaped baffle 37 is connected in the internal thread. When the arc-shaped baffle 37 is locked, it can wrap around the outer circle of the bushing 5 to protect the bushing 5. And the arc-shaped baffle 37 is located at a certain distance above the upper surface of the support ring 35 and will not affect the fixation of the bushing 5;

[0079] To sum up, before clamping the bushing 5, place the bushing 5 on the upper end of the support ring 35 and pass the positioning hole 512 through the limit post 36. At this time, since the arc-shaped baffle 37 has not been installed yet, it does not affect the placement of the bushing 5;

[0080] Subsequently, install the arc-shaped baffle 37 and rotate the arc-shaped baffle 37 to the outer circle of the bushing 5 and lock it to protect the outer circle of the bushing 5;

[0081] Subsequently, the lifting seat 21 rises and drives the first rack 33 to rise synchronously. Through the action of the first gear 34, the second gear 67 rotates. At this time, the toothed plate 65 starts to descend synchronously to facilitate docking with the tooling seat 210;

[0082] After the tooling seat 210 contacts the bushing 5, the bushing 5 disengages from the upper surface of the support ring 35, and synchronously moves upward with the tooling seat 210 and performs a clamping action;

[0083] It should be noted that the upper end of the second rack 68 has a limited length. Thus, when the bushing 5 disengages from the upper surface of the support ring 35, the second gear 67 also reaches the upper end of the second rack 68, so that the support ring 35 will not descend an excessive distance;

[0084] And at this time, because the arc baffle 37 is located at a certain distance above the upper surface of the support ring 35, the distance that the bushing 5 rises does not cause the upper surface of the flange 511 to exceed the lower end of the arc baffle 37. Therefore, the arc baffle 37 can still be used to protect the bushing 5;

[0085] After the bending of the bushing 5 is completed, the lifting seat 21 retracts. Thus, according to the reverse actions described above, the support ring 35 starts to rise and re-supports the bushing 5, and then the bushing 5 can be removed from the support ring 35.

[0086] During the disassembly process of the bushing 5, due to the pressure during bending, the bushing 5 adheres to the lower jacking shaft 211 and it is difficult to strip the material. To solve this problem, as Figure 7 - Figure 8 shown, a fixed plate 61 is fixedly installed on the base 1. The upper end of the fixed plate 61 is provided with a fixed ring 62. A locking shaft 611 is slidably inserted through the fixed ring 62. The lower end of the locking shaft 611 is fixedly installed with a toothed plate 65. Thus, when the toothed plate 65 moves, it can drive the locking shaft 611 to move synchronously;

[0087] At the same time, a first spring 66 is arranged between the lower end of the toothed plate 65 and the fixed ring 62. The first spring 66 is sleeved on the outer ring of the locking shaft 611. Thus, when the toothed plate 65 moves, it can stretch or compress the first spring 66;

[0088] In this embodiment, a boss (not marked in the figure) is provided on the locking shaft 611 to prevent the locking shaft 611 from slipping out of the fixed ring 62 during sliding;

[0089] Thus, when the second gear 67 rotates, it can drive the toothed plate 65 to slide vertically through the engaged second rack 68 and stretch or compress the first spring 66;

[0090] Continue to refer to Figure 7 - Figure 8 , a chute 651 is formed in the toothed plate 65. An independent tooth 69 is slidably arranged in the chute 651. A second spring 610 is fixedly installed between the independent tooth 69 and the toothed plate 65. Thus, in the initial state, due to the action of the second spring 610, there is a certain distance between the independent tooth 69 and one end of the second rack 68, and this distance is the tooth pitch length of the second rack 68;

[0091] In summary, when the bending of the bushing 5 is completed, the lifting seat 21 retracts, and the second gear 67 rotates. As the second gear 67 rotates, the toothed plate 65 is driven to move vertically upward, stretching the first spring 66.

[0092] As the second gear 67 continues to rotate, the second gear 67 will cross the end on the other side of the second rack 68 and engage with the independent tooth 69. When the second rack 68 engages with the independent tooth 69, the independent tooth 69 will be driven to approach the second rack 68 and, under the action of the second spring 610, disengage from the engagement.

[0093] As the second gear 67 continues to rotate, when the second gear 67 disengages from the independent tooth 69, the independent tooth 69 will reset under the action of the second spring 610 and drive the toothed plate 65 to reset a short distance, causing the toothed plate 65 to retract.

[0094] Thus, through the continuous rotation of the second gear 67 described above, intermittent engagement with the independent tooth 69 can be achieved, driving the toothed plate 65 to vibrate intermittently, and then driving the support ring 35 to vibrate intermittently, continuously vibrating the bottom of the flange 511 to assist the bushing 5 to be disengaged from the lower jackshaft 211.

[0095] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
