Description

Technical Field

[0001] The present invention relates to the technical field of shock absorber production equipment, and in particular to an assembly device for producing automobile shock absorbers. Background Art

[0002] Automotive shock absorbers are core components of the vehicle's suspension system. They primarily suppress the rapid rebound motion of the shock absorber spring after absorbing road impact energy and compressing it. They also attenuate road shock, directly optimizing the vehicle's handling stability, ride comfort, and driving safety. The top rubber, a key cushioning element, is installed at the junction of the shock absorber's top and the vehicle body. It is typically composed of a metal frame and vulcanized rubber.

[0003] During the assembly of the shock absorber, the top glue must be installed when the shock absorber spring is in a pre-compressed state. In the traditional assembly station, this step is mainly completed by a claw-type spring compressor. During this process, the operator needs to synchronously and gradually compress both sides of the shock absorber spring until its length is shortened enough to expose the thread at the top of the piston rod. The staff then fixes the top glue on the piston rod of the shock absorber. After completing the installation of the top glue, the industrial robot transports the assembled shock absorber to the next processing location.

[0004] During the process of compressing the shock absorber spring, if the compressor is not tightened synchronously, or the claws of the compressor are not completely embedded in the shock absorber spring coil, the shock absorber spring will separate from the compressor during the compression process, causing the shock absorber spring to disengage. The shock absorber spring after disengagement will pop out quickly due to its own elastic potential energy, causing the shock absorber spring to collide with other surrounding equipment or even staff, posing a threat to the safety of the staff.

[0007] It is further explained that when the extrusion blocks are in contact with the shock-absorbing spring, the projections of the four extrusion blocks on the horizontal plane are evenly distributed in the circumferential direction.

[0008] It is further explained that a groove is provided on the lower side of the extrusion block, and the groove on the lower side of the extrusion block is composed of two inclined arc surfaces, and the distance between the two inclined arc surfaces gradually decreases from bottom to top.

[0010] Further description: the connecting block is rotatably connected to a first threaded rod, and the first threaded rod is threadedly connected to the second pulley.

[0011] It is further explained that the diameter of the damping rod gradually decreases from top to bottom, the aperture of the through hole on the movable rod is larger than the maximum diameter of the corresponding damping rod, and the heights of all the damping rods in the same first liquid storage shell are different.

[0012] Further description, it also includes several fixing components, the number of the fixing components is the same as the number of the extrusion blocks, the fixing components are used to change the position of the corresponding extrusion blocks, the fixing components are arranged on the corresponding connecting blocks, the fixing components include a fixing block, a mounting block and a second threaded rod, the fixing block is slidably connected to the adjacent connecting block, the mounting block is slidably connected to the fixing block, the second threaded rod is rotatably connected to the mounting block, the second threaded rod passes through the fixing block and is threadedly connected to it, and the mounting block is provided with a blind hole for the adjacent extrusion block to move.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the present invention connects adjacent fixing ropes and shock-absorbing springs respectively through symmetrically distributed lock buckles. When the shock-absorbing spring is disengaged, the shock-absorbing spring is fixed by the symmetrically distributed fixing ropes, thereby reducing the release speed of the elastic potential energy of the shock-absorbing spring, thereby reducing the threat posed by the shock-absorbing spring to the personal safety of the staff after the shock-absorbing spring is disengaged.

[0017] The damping rod blocks the adjacent through holes on the adjacent moving rods, thereby increasing the resistance to the upward movement of the moving rod, reducing the upward movement speed of the moving rod, and then reducing the upward movement speed of the shock-absorbing spring, slowing down the release speed of the elastic potential energy of the shock-absorbing spring, and limiting the displacement range of the shock-absorbing spring, thereby reducing the harm caused by the shock-absorbing spring when it is tripped.

[0018] After the extrusion block contacts the shock-absorbing spring, it is rotated relative to the adjacent connecting disk under the force of the shock-absorbing spring, thereby rotating the extrusion block from a horizontal state to an inclined state, increasing the contact area between the extrusion block and the shock-absorbing spring, thereby increasing the force-bearing area of ​​the shock-absorbing spring, improving the stability of the shock-absorbing spring during the compression process, and reducing the probability of tripping.

DETAILED DESCRIPTION

[0021] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 This embodiment discloses an assembly device for automobile shock absorber production, which aims to improve existing automobile shock absorber assembly equipment.

[0023] like Figures 1-6As shown, the assembly equipment for automobile shock absorbers includes a fixing frame 1, the fixing frame 1 is fixedly connected to a mounting seat 2, and the mounting seat 2 is provided with a fixing module for fixing the shock absorber, and the fixing module is an existing device. A moving block 3 is slidably connected to the fixing frame 1, and a moving module for driving the moving block 3 to move is provided on the fixing frame 1. The moving module is an existing device, and the figure shows an electric push rod as an example. A connecting module is provided on the moving block 3, and the connecting module of the fixing frame 1 is used to drive the connecting block 4 to move. The connecting module is an existing device, and the figure shows an electric shaft as an example, and the electric shaft is provided with two threads symmetrically distributed on the left and right. The moving block 3 is provided with two connecting blocks symmetrically distributed on the left and right through the connecting module thereon, and the two connecting blocks 4 are respectively threadedly connected to different threaded portions on the electric shaft, and the connecting block 4 is provided with two extrusion blocks symmetrically distributed front and back. Pressure block 5. In this embodiment, the extrusion block 5 is fixedly connected to the adjacent connecting block 4. The specific position of the extrusion block 5 is specifically selected by the staff. A rubber layer is provided on the lower side of the extrusion block 5 to increase the friction between the extrusion block 5 and the shock-absorbing spring. The extrusion block 5 is used to extrude the shock-absorbing spring. The connecting block 4 is provided with a fixing rope 6. The fixing rope 6 is used to reduce the release speed of the elastic potential energy of the shock-absorbing spring when the shock-absorbing spring is tripped. The fixing rope 6 is located between two adjacent extrusion blocks 5. The fixing rope 6 is fixedly connected with a lock buckle 7. The lock buckle 7 is used to fix the fixing rope 6 to the shock-absorbing spring. A transfer robot 8 is provided on one side of the fixed frame 1. The transfer robot 8 is an existing device and its working process will not be described in detail. The transfer robot 8 is used to transport the assembled shock absorber. A connecting component is provided on the connecting block 4. The connecting component is used to change the tension of adjacent fixing ropes 6.

[0024] like Figure 2 As shown, when the extrusion blocks 5 are in contact with the shock-absorbing spring, the projections of the four extrusion blocks 5 on the horizontal plane are evenly distributed in the circumferential direction, ensuring that the shock-absorbing spring can be subjected to evenly distributed extrusion force.

[0025] like Figure 7 As shown, a groove is provided on the lower side of the extrusion block 5. The groove on the lower side of the extrusion block 5 is composed of two inclined arc surfaces, and the distance between the two inclined arc surfaces gradually decreases from bottom to top, which is used to increase the contact area between the extrusion block 5 and the shock-absorbing spring and improve the stability of the shock-absorbing spring when it is compressed.

[0026] like Figure 3-Figure 6As shown, the connecting assembly includes a first pulley 9, a second pulley 10, a first liquid storage shell 12, a moving rod 13 and a plurality of damping rods 14. The first pulley 9 is rotatably connected to the upper side of the connecting block 4, and the second pulley 10 is slidably connected to the connecting block 4. The fixing rope 6 passes around the first pulley 9 and the second pulley 10 to change the force direction of the fixing rope 6 away from one end of the lock buckle 7, so that the end moves vertically. The first liquid storage shell 12 is fixed to the lower side of the connecting block 4. Hydraulic oil is stored in the first liquid storage shell 12. The moving rod 13 is sealingly and slidingly connected to the first liquid storage shell 12, the moving rod 13 is fixedly connected to the fixed rope 6, and the fixed rope 6 drives the moving rod 13 to move vertically. Several damping rods 14 are fixedly connected to the first liquid storage shell 12. The specific number of damping rods 14 can be selected by the staff and is not further defined in this article. Several through holes are provided on the moving rod 13, and the number of through holes on the moving rod 13 is the same as the number of damping rods 14. The damping rods 14 are used to reduce the flow area of ​​adjacent through holes on the moving rod 13.

[0027] like Figure 4 and Figure 5 As shown, the connecting block 4 is rotatably connected to a first threaded rod 11 , and the first threaded rod 11 is threadedly connected to the second pulley 10 . The height of the second pulley 10 can be changed by rotating the first threaded rod 11 .

[0028] like Figure 6 As shown, the diameter of the damping rod 14 gradually decreases from top to bottom, the aperture of the through hole on the moving rod 13 is larger than the maximum diameter of the corresponding damping rod 14, and the heights of all the damping rods 14 in the same first liquid storage shell 12 are different, so that when the moving rod 13 moves upward, the through hole on the moving rod 13 is gradually blocked by the adjacent damping rod 14.

[0029] When it is necessary to use this device to install the shock absorber top glue, the staff first fixes the shock absorber on the fixing module of the mounting seat 2, then places the shock absorber spring on the shock absorber, and controls the two connecting blocks 4 to move closer to each other through the connecting module, and the two connecting blocks 4 drive all the parts on them to move synchronously.

[0030] When the two connecting blocks 4 are approaching each other, the staff starts the moving module, and the moving module drives the moving block 3 to move slowly downward, and the moving block 3 drives the two connecting blocks 4 to move downward synchronously until the four extrusion blocks 5 are moved to the position in contact with the shock-absorbing spring (the two inclined surfaces on the extrusion block 5 are in contact with the shock-absorbing spring, and the shock-absorbing spring is stuck in the groove of the four extrusion blocks 5). The staff shuts down the connecting module and the moving module, and then fixes the two lock buckles 7 on the left and right sides of the shock-absorbing spring respectively. After the fixation is completed (at this time, the two fixed ropes 6 are in a relaxed state), the staff rotates the two first threaded rods 11, and the first threaded rods 11 drive the adjacent second pulley 10 to move, adjust the position of the second pulley 10, and thus change the tension of the fixed rope 6.

[0031] After the positions of the two second pulleys 10 are adjusted (the two fixed ropes 6 are in a tensioned state), stop rotating the two first threaded rods 11, and start the moving module again, so that the two connecting blocks 4 drive all the parts thereon to move downward synchronously, and in this process, the four extrusion blocks 5 jointly squeeze the shock-absorbing spring to compress it. When the height of the upper side of the shock-absorbing spring is lower than the upper end of the shock absorber piston rod, the staff shuts down the moving module and then fixes the top glue on the piston rod. After the fixation is completed, the staff controls the moving module to drive the four extrusion blocks 5 to move upward. In the process of the extrusion block 5 moving upward, the shock-absorbing spring gradually stretches under the action of its own elastic force until the upper side of the shock-absorbing spring contacts the lower side of the top glue, and the shock-absorbing spring stops stretching. At this time, the moving module continues to drive the four extrusion blocks 5 to move upward until the extrusion block 5 is separated from the shock-absorbing spring.

[0032] After the four extrusion blocks 5 are separated from the shock-absorbing spring, the staff shuts down the moving module, then removes the two locks 7 from the shock-absorbing spring, and starts the connecting module to move the two connecting blocks 4 away from each other. After the distance between the two connecting blocks 4 reaches the maximum, the staff shuts down the connecting module, and controls the moving module again to drive the moving block 3 to move upward to the initial position, and then starts the transfer robot 8, which transfers the assembled shock absorber to the next processing stage.

[0033] During the above-mentioned compression process of the shock-absorbing spring, when the shock-absorbing spring is not accurately inserted into the grooves of the four extrusion blocks 5 (such as due to improper positioning of the extrusion blocks 5, etc.), or the shock-absorbing spring is subjected to uneven force during the compression process, the shock-absorbing spring may be separated from the four extrusion blocks 5 (i.e., "tripped"). After tripping, the elastic potential energy stored in the shock-absorbing spring is instantly released, thereby posing a threat to the personal safety of the staff. The present invention solves the above-mentioned problem through the following measures.

[0034] When the shock-absorbing spring is tripped, the elastic potential energy stored in it is released instantly, causing the shock-absorbing spring to move upward. At this time, the two lock buckles 7 are still connected to the shock-absorbing spring, so that the shock-absorbing spring drives the two lock buckles 7 to move synchronously during the upward movement. The lock buckles 7 drive the adjacent moving rods 13 to move synchronously through the adjacent fixed ropes 6, causing the moving rods 13 to move vertically upward (the moving rods 13 move upward along the adjacent first liquid storage shells 12, causing the hydraulic oil in the first liquid storage shells 12 to flow through the through holes on the adjacent moving rods 13). During the upward movement of the moving rods 13, the damping rod 14 enters the adjacent moving rods 13, the adjacent through holes on the adjacent moving rods 13 are blocked, and the flow area of ​​the through holes is reduced to increase the resistance to the upward movement of the moving rod 13 (as the upward movement distance of the moving rod 13 increases, the damping rod 14 located in the through hole of the moving rod 13 also increases accordingly, so that the resistance to the upward movement of the moving rod 13 increases synchronously), thereby reducing the upward movement speed of the moving rod 13, and then reducing the upward movement speed of the shock-absorbing spring, slowing down the release speed of the elastic potential energy of the shock-absorbing spring, and limiting the displacement range of the shock-absorbing spring, thereby reducing the harm caused by the shock-absorbing spring when it is tripped.

[0035] After the shock-absorbing spring stops moving, the staff will inspect and repair the device to prepare for subsequent normal use.

[0036] Example 2 Based on Example 1, this example continues to optimize the existing automobile shock absorber assembly equipment.

[0037] like Figure 3-Figure 5 and Figure 7 As shown, it also includes several fixing components, the number of which is the same as the number of extrusion blocks 5, and the fixing components are used to change the position of the corresponding extrusion blocks 5. The fixing components are arranged on the corresponding connecting blocks 4, and the fixing components include a fixing block 15, a mounting block 16 and a second threaded rod 17. The fixing block 15 is slidably connected to the adjacent connecting block 4, the mounting block 16 is slidably connected to the fixing block 15, the mounting block 16 slides along the fixing block 15, and the second threaded rod 17 is rotatably connected to the mounting block 16. The second threaded rod 17 passes through the fixing block 15 and is threadedly connected thereto. The adjacent mounting block 16 is driven left and right by the second threaded rod 17 during the rotation process, and the mounting block 16 is provided with a blind hole for movement of the adjacent extrusion block 5.

[0038] like Figure 7As shown, it also includes a plurality of connecting plates 18, the number of which is the same as the number of extrusion blocks 5, and the connecting plates 18 are slidably connected to the blind holes of the adjacent mounting blocks 16. In the initial state, the connecting plates 18 can no longer move in the direction away from the adjacent second threaded rod 17, and the connecting plates 18 are rotatably connected to the adjacent extrusion blocks 5, so that when the extrusion blocks 5 contact with the shock-absorbing spring, they can rotate as the pitch angle of the shock-absorbing spring changes, thereby ensuring the contact relationship between the extrusion blocks 5 and the shock-absorbing spring, and a connecting spring is provided between the connecting plates 18 and the adjacent mounting blocks 16, and the connecting spring is used to drive the connecting plates 18 to reset, and at the same time, the extrusion blocks 5 can be subjected to the extrusion force of the shock-absorbing spring and move laterally during the compression of the shock-absorbing spring.

[0039] like Figure 3-Figure 5 As shown, the connecting block 4 is provided with two symmetrically distributed front-to-back sliding grooves, and two guide rods 19 symmetrically distributed front-to-back are fixedly connected in the sliding grooves of the connecting block 4. The fixed block 15 slides in the adjacent sliding grooves on the adjacent connecting block 4. In the initial state, the fixed block 15 is located in the middle of the adjacent sliding grooves on the adjacent connecting block 4. The guide rod 19 passes through the adjacent fixed block 15 and is slidably connected thereto. The moving direction of the adjacent fixed block 15 is limited by the guide rod 19 so that the fixed block 15 can only move up and down. The connecting block 4 is fixed with two second liquid storage shells 20 symmetrically distributed front-to-back. Hydraulic oil is stored in the second liquid storage shell 20. A fixed rod 21 is sealed and slidably connected in the second liquid storage shell 20. The upper part of the fixed rod 21 is connected to the second liquid storage shell 2 0 sealed sliding connection, the lower part is not sealed and slidably connected with the second liquid storage shell 20. In the initial state, the length of the portion of the fixing rod 21 located outside the adjacent second liquid storage shell 20 is half of its total length. The fixing rod 21 is slidably connected to the adjacent connecting block 4. The fixing rod 21 is fixedly connected to the adjacent fixing block 15. The adjacent fixing blocks 15 are driven by the fixing rod 21 to move synchronously. The two second liquid storage shells 20 on the same connecting block 4 are fixedly connected and connected by a connecting pipe 22, so that the hydraulic oil between the two second liquid storage shells 20 on the same connecting block 4 can flow through the adjacent connecting pipe 22, so that when one of the two fixing rods 21 on the same connecting block 4 moves downward, the other fixing rod 21 moves upward.

[0040] like Figure 5 As shown, there is friction between the fixing rod 21 and the adjacent second liquid storage shell 20, so that the fixing rod 21 can be maintained in the initial position, while reducing the height difference between the two extrusion blocks 5 on the same connecting block 4 when they contact the shock-absorbing spring, ensuring that the four extrusion blocks 5 can apply uniform extrusion force to the shock-absorbing spring.

[0041] When the device is needed to compress the shock-absorbing spring, the staff first moves the two connecting blocks 4 to the working position (when the distance between the two connecting blocks 4 is the smallest) according to the above operation, and then adjusts the initial position of the four extrusion blocks 5 according to the specifications of the shock-absorbing spring. The movement process of the extrusion block 5 on the left front side is described as an example. The specific process is as follows: The second threaded rod 17 is rotated, and the mounting block 16 is driven to move by the second threaded rod 17 during the rotation process, and the mounting block 16 drives the extrusion block 5 thereon to move synchronously. After the extrusion block 5 moves to the working position, the staff stops rotating the second threaded rod 17, and then changes the position of the fixed block 15 according to the pitch angle of the shock-absorbing spring (the downward movement of the fixed block 15 is described as an example). During the downward movement, the fixed block 15 drives the extrusion block 5 to move synchronously through the mounting block 16. When the extrusion block 5 moves downward to contact the shock-absorbing spring, as the extrusion block 5 continues to move downward, the extrusion block 5 is rotated relative to the connecting plate 18 by the force of the shock-absorbing spring, so that the extrusion block 5 rotates from a horizontal state to an inclined state, thereby increasing the contact area between the extrusion block 5 and the shock-absorbing spring, thereby increasing the force-bearing area of ​​the shock-absorbing spring, improving the stability of the shock-absorbing spring during compression, and reducing the risk of tripping.

[0042] After the left front extrusion block 5 rotates to the tilted state, the left connecting block 4 continues to move downward, so that the left front extrusion block 5 is moved upward relative to the connecting block 4 by the force of the shock-absorbing spring, thereby driving the left front mounting block 16 to move upward synchronously, and the left front mounting block 16 drives the adjacent fixing rod 21 to move upward relative to the adjacent second liquid storage shell 20, and the hydraulic oil in the adjacent second liquid storage shell 20 is squeezed by the left front fixing rod 21 during the upward movement, so that the hydraulic oil in the left front second liquid storage shell 20 flows into the left rear second liquid storage shell 20 through the adjacent connecting pipe 22, thereby causing the left rear fixing rod 21 to move downward under the pressure of the hydraulic oil, and the left rear fixing rod 21 drives the adjacent mounting block 16 to move downward synchronously through the transmission of the adjacent fixing block 15, and the left rear mounting block 16 drives the adjacent extrusion blocks 5 to move downward synchronously, so that the two extrusion blocks 5 on the left have a height difference, so that the positions of the two extrusion blocks 5 adapt to the rotation direction of the shock-absorbing spring, further improving the stability of the shock-absorbing spring during the compression process.

[0043] Until the extrusion block 5 on the left rear side contacts the shock-absorbing spring, the connecting block 4 on the left squeezes the shock-absorbing spring through the two extrusion blocks 5 on the left. In the process of the shock-absorbing spring being compressed, its pitch angle gradually decreases, so that the height difference between the contact positions of the two extrusion blocks 5 on the left and the shock-absorbing spring also decreases. In this process, the two extrusion blocks 5 on the left produce relative movement again (the extrusion block 5 on the left front side moves downward relative to the extrusion block 5 on the left rear side), and at the same time, the angle between the two extrusion blocks 5 on the left and the horizontal plane also decreases, thereby maintaining the stability of the contact area between the two extrusion blocks 5 on the left and the shock-absorbing spring, and improving the uniformity of the force on the shock-absorbing spring.

[0044] During the compression of the shock-absorbing spring, the pitch angle of the shock-absorbing spring decreases and the outer diameter of the shock-absorbing spring gradually increases, so that the two extrusion blocks 5 on the left are driven by the extrusion force of the shock-absorbing spring to drive the adjacent connecting plates 18 to move relative to the adjacent mounting blocks 16. Even if the extrusion blocks 5 slide along the blind holes of the adjacent mounting blocks 16, the lateral restraining force between the extrusion blocks 5 and the shock-absorbing spring is reduced, ensuring that the shock-absorbing spring can be compressed smoothly.

[0045] The movement process of the two extrusion blocks 5 on the right side can refer to the movement process of the two extrusion blocks 5 on the left side mentioned above, and will not be repeated. When the height of the upper side of the shock absorber spring is lower than the height of the upper end of the shock absorber piston rod, the staff will install the top glue on the shock absorber according to the above operation, and separate the four extrusion blocks 5 from the shock absorber spring according to the above operation. After separation, the assembled shock absorber is transferred to the next processing flow by the transfer robot 8, and the moving block 3 is reset upward to the initial position. In this process, since the shock absorbers are produced in large quantities, there is no need to additionally change the relative position of the extrusion block 5 and the adjacent fixed block 15. After the assembly of the shock absorbers of the same batch is completed, when other shock absorbers need to be assembled, the staff can adjust the positions of the four extrusion blocks 5 according to the above operation.

[0046] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed in the present application based on the technical solution and its improved ideas, which should be covered by the scope of protection of the present application.
