Description

Technical Field

[0001] The present application relates to the technical field of hydraulic bushing forming equipment, and specifically to a bending equipment 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 realizes damping and stiffness adjustment through liquid flow, and improves the vibration damping performance and comfort of the system; 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, and is connected by a narrow flow channel (inertia channel); When a hydraulic bushing is subjected to an external force, the liquid flows between the two liquid chambers to form 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; During the production process of the hydraulic bushing, 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, it is necessary to use bending equipment to lock the hydraulic bushing with the outer shell; 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 equipment for vehicle hydraulic bushings to solve the above problems.

[0003] 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

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] Embodiment 1:

[0023] This embodiment mainly describes the specific structure of a hydraulic bushing for a vehicle (hereinafter referred to as the bushing), and the structure and working principle of a bending device for bending the bushing, specifically: Figures 3 - 4 The bushing 5 that needs to be bent in this application is shown. The bushing 5 is a hydraulic bushing, which is a front lower arm bushing of a passenger car designed with a hydraulic structure. The product has a high damping characteristic and can greatly attenuate the low-frequency and large-amplitude vibration of the whole vehicle; The bushing 5 includes an inner core 55, which is the innermost ring structure of the bushing 5 and has a through hole 551, which is used as a positioning hole in the subsequent bending process; The outer ring of the inner core 55 is integrally vulcanized with a rubber 52, and a skeleton 54 is provided inside the rubber 52, and the skeleton 54 is used to support the rubber 52 to maintain the strength of the rubber 52; At the same time, an outer spring 53 is arranged on the outer ring of the rubber 52, and a flow channel 521 that can be filled with liquid is formed between the outer spring 53 and the rubber 52, so that when the outer spring 53 and the rubber 52 are assembled, the flow channel 521 is filled with liquid to form a bushing assembly; When the bushing 5 is assembled, in order to protect the bushing 5, a jacket 51 is provided on the outer ring of the bushing 5, and a locking claw 522 is provided on the bushing 5. The locking claw 522 is used to lock the bushing 5 and the jacket 51 to prevent the lateral force of the vehicle during driving from causing the bushing 5 to be separated because there is no outer shell, thereby ensuring driving safety; It can be understood that the bending process refers to the operation process of clamping the sleeve 5 with the outer sleeve 51 through the locking claw 522. In the initial state, the locking claw 522 is parallel to the axis of the sleeve 5. After bending, the locking claw 522 is turned outward and clamped on the outer sleeve 51 (refer to Figure 4 In the present application, six groups of locking claws 522 are arranged along the circumferential direction, and the six groups of locking claws 522 are bent in sequence to hold and fix the outer sleeve 51; To perform the above bending operation, Figures 1 - 2Shown is a bending device for the bushing 5. The bending device includes a clamping mechanism 2, which is used to clamp and fix the combination of the bushing 5 and the outer sleeve 51 when bending the locking claw 522; 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, and this slideway is used to guide the movement of the lifting seat 21 so that the lifting seat 21 reciprocates vertically more stably; As Figures 5 - 6 shown, a connecting shaft 29 is installed on the lifting seat 21 by bearings. It should be noted that a servo system (not shown in the figure) is provided inside the lifting seat 21, and the output end of this 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; 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) matching 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 circle 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; To position the upper end of the bushing 5, a shaft seat 24 is fixedly installed on the base 1. The lower end of the shaft seat 24 is fixedly or rotatably provided with an upper jacking shaft 241, and the upper jacking shaft 241 is adapted to be inserted into the upper end of the through hole 551 to limit the bushing 5; As Figures 1 - 2 shown, a calibrator 27 is provided on the shaft seat 24. The calibrator 27 can adopt an optoelectronic sensor to calibrate the position where the bushing 5 needs to be bent; To bend the locking claw 522, as Figures 9 - 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; Combined with Figures 1 - 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 into the position where the bushing 5 is clamped through the window 11; At the same time, a side plate 25 is fixedly installed at the lower end of the shaft seat 24, and the output end of the cylinder 42 is hinged with a rotating seat 43. The two sides of the rotating seat 43 are provided with pin shafts 26, and the pin shafts 26 are installed on the side plate 25 by bearings. Thus, when the cylinder 42 expands and contracts, the rotating seat 43 can rotate on the side plate 25; Continue to refer to Figures 9 - 10, a bending seat 44 is fixedly installed on the rotating seat 43, a pressing head 45 is fixedly installed on the bending seat 44, and the pressing head 45 is adapted to the locking claw 522, and can perform a bending action on the single locking claw 522; To prevent the bushing 5 from always remaining in the locked state during bending, as Figures 5 - 6 shown, a coupling 28 is sleeved outside the connecting shaft 29, a locking rod 23 is fixedly installed on the coupling 28, and the locking rod 23 is adapted to rotate with the coupling 28; At the same time, a stopper 22 is fixedly installed on the base 1, and 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 in the locked state during bending; 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; In this embodiment, the rotation of the coupling 28 can be manually controlled or controlled by a servo motor, and no further limitation is made here; More preferably, a PLC control system is also provided in this application to facilitate the coordinated operation of each electrical component; 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, an anti-fooling pin is provided in the tooling seat 210 to ensure the correct placement position of the bushing 5; At this time, the lower jacking shaft 211 abuts against the lower end of the through hole 551. Subsequently, the bending device is started, the jacking seat 21 is lifted, 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 the locked state during bending (ensuring safety and controlling the defective rate). After the bushing 5 is locked, after the bending device self-inspects that all positions are correct, the cylinder 42 starts to drive the pressing head 45 to move. The pressing head 45 always fits on the surface to be bent and performs a point arc movement. Calculate the piston travel distance of the cylinder 42 to make the pressing head 45 perform an arc movement of 90 degrees (the piston stroke limit of the cylinder can be adjusted to meet different angle bends); After bending, the 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, and so on 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 taken out manually, and the next bushing 5 is loaded to complete the next cycle.

[0024] Embodiment Two:

[0025] During the clamping and relaxation of the bushing 5, due to positioning and clamping through the lower jackshaft 211 and the upper jackshaft 241, during the bending process, the bushing 5 will adhere to the lower jackshaft 211, resulting in difficulty in stripping the bushing 5; To solve the above problems, as Figure 1 and Figures 6 - 7 shown, a lifting mechanism 3 is provided on the lifting 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 lifting seat 21, and the first rack 33 can move vertically synchronously with the lifting seat 21; At the same time, two sets of bearing seats 31 are fixedly installed on the base 1, a rotating shaft 32 is installed between the two sets of bearing seats 31, a first gear 34 is fixedly installed on the rotating shaft 32, and 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 further drive the rotating shaft 32 to rotate; As Figures 6 - 7 shown, a stripping mechanism 6 is provided on one side of the rotating shaft 32. The stripping mechanism 6 is used to strip the bushing 5 from the clamped state after bending. The stripping 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; At the same time, 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; 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 larger than the outer diameter of the tooling seat 210. Therefore, the tooling seat 210 can pass through the support ring 35 without obstruction, 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 provided on the flange 511, and the positioning hole 512 can be used as a positioning reference during the bending process; As Figure 7As shown, 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 provided at the upper end of the limit post 36, and an arc-shaped baffle 37 is connected to the internal thread. When locked, the arc-shaped baffle 37 can wrap around the outer ring 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; In summary, 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; Subsequently, install the arc-shaped baffle 37 and rotate the arc-shaped baffle 37 to the outer ring of the bushing 5 and lock it to protect the outer ring of the bushing 5; 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; When the tooling seat 210 contacts the bushing 5, the bushing 5 separates from the upper surface of the support ring 35 and moves up synchronously with the tooling seat 210 and performs a clamping action; It should be noted that the upper end length of the second rack 68 is limited. Thus, when the bushing 5 separates 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; And at this time, since the arc-shaped baffle 37 is located at a certain distance above the upper surface of the support ring 35, the rising distance of the bushing 5 does not cause the upper surface of the flange 511 to exceed the lower end of the arc-shaped baffle 37. Therefore, the arc-shaped baffle 37 can still be used to protect the bushing 5; After the bushing 5 is bent, the lifting seat 21 retracts. Thus, according to the reverse actions described above, the support ring 35 starts to rise and supports the bushing 5 again. Subsequently, the bushing 5 can be removed from the support ring 35.

[0026] During the disassembly process of the bushing 5, due to the pressure during bending, the bushing 5 adheres to the lower jackshaft 211 and is difficult to strip. To solve this problem, as Figures 7 - 8 shown, a fixing plate 61 is fixedly installed on the base 1. A fixing ring 62 is installed at the upper end of the fixing plate 61. A locking shaft 611 is slidably inserted through the fixing ring 62. The locking shaft 611 is fixedly installed at the lower end of the toothed plate 65. Thus, when the toothed plate 65 moves, it can drive the locking shaft 611 to move synchronously; Meanwhile, 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 circle of the locking shaft 611. Thus, when the toothed plate 65 moves, the first spring 66 can be stretched or compressed. In this embodiment, a boss (not marked in the figure) is arranged on the locking shaft 611 to prevent the locking shaft 611 from slipping out of the fixed ring 62 during sliding. Thus, when the second gear 67 rotates, the toothed plate 65 can be driven to slide vertically through the engaged second rack 68, and the first spring 66 can be stretched or compressed. Continue to refer to Figures 7 - 8 , a chute 651 is formed in the toothed plate 65. An independent tooth 69 is slidably arranged in the chute 651. And 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. To sum up, when the bending of the bushing 5 needs to be completed, the lifting seat 21 retracts, and the second gear 67 rotates. Thus, as the second gear 67 rotates, the toothed plate 65 is driven to move vertically upward, and the first spring 66 is stretched. 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. 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 move backward. Thus, through the continuous rotation of the second gear 67 as described above, intermittent engagement with the independent tooth 69 can be achieved to drive the toothed plate 65 to vibrate intermittently, and then drive the support ring 35 to vibrate intermittently, thereby continuously vibrating the bottom of the flange 511 to assist the bushing 5 to be disengaged from the lower jacking shaft 211.

[0027] The above are only the preferred embodiments of the present application and are not used 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.
