Description

Technical Field

[0001] This invention relates to the field of shock absorber assembly technology, specifically to an auxiliary assembly device for automotive shock absorbers. Background Technology

[0002] The shock absorber is a core component of the automotive suspension system and belongs to the category of vibration damping devices. Its main function is to attenuate vibrations caused by road impacts, thereby improving ride comfort and handling safety. It converts mechanical energy into heat energy through hydraulic or gas damping. During the suspension compression stroke, it reduces resistance to buffer impacts, and during the extension stroke, it increases resistance to suppress rebound and ensure wheel grip. The process of precisely assembling and installing the various components of the shock absorber according to the design drawings ensures its core function, thereby achieving the goal of attenuating road impacts and improving ride comfort and safety. Automotive shock absorbers are composed of multiple components. After the main components of the automotive shock absorber are assembled, some parts are semi-automated by a combination of manual labor and equipment. When assembling the pressure cap of the shock absorber, the spring seat and the pressure cap of the shock absorber are connected. Then, a certain pressure is applied by external pressing equipment to complete the pressing of the spring seat and the pressure cap of the shock absorber. Patent CN118321873A discloses a processing device for the pressure cap of an automotive shock absorber spring seat, relating to the field of automotive shock absorber processing technology. This processing device includes a processing turntable, a clamping mechanism, a rotating mechanism, mounting openings, a swivel assembly, a lifting assembly, and a bearing mechanism. Multiple sets of mounting openings are integrally formed on the surface of the processing turntable and arranged in a circular array. The clamping mechanism is located inside the mounting openings and is used to clamp and fix the pressure cap. The rotating mechanism is located between the processing turntable and the clamping mechanism. This processing device, in conjunction with equipment that transports the spring seat and pressure cap into the mounting openings, can automatically complete the pre-assembly of the pressure cap and the spring seat, and clamp and fix the spring seat, ensuring the stability of subsequent assembly operations between the pressure cap and the spring seat, and meeting the clamping requirements of spring seats of different specifications.

[0003] The above-mentioned device has certain shortcomings in its use: during assembly, the shock absorbers need to be manually picked up and placed into the clamping mechanism one by one, and then connected with the pressure cap after being fixed. The assembly is completed by pressing equipment. Since both the shock absorber and the pressure cap have a certain weight, the manual labor intensity will be increased after frequent picking, connecting and assembling. In addition, due to the difference in the specifications of the shock absorbers, there may be deviations when the spring seat and the pressure cap are connected, resulting in the problem of insecure pressing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This automotive shock absorber auxiliary assembly device, when assembling the shock absorber and pressure cap, first transports them step by step, eliminating the need for manual handling. This reduces the labor intensity of workers and improves assembly efficiency. After the shock absorber and pressure cap are gradually transported to the position of the push-press assembly, the transport assembly waits for a preset time. Then, the fixed assembly descends, driving the push-press assembly to push the pressure cap to the position of the shock absorber and apply a certain pressure to complete the assembly. The entire assembly process involves the synchronous transport of the shock absorber and pressure cap, and the docking assembly is completed by the push-press assembly. This device has good work efficiency when assembling components, improving the problems of high labor intensity, long working hours leading to docking deviations, and insecure pressing caused by manual assembly. It also significantly improves the assembly progress of the shock absorber.

[0016] 2. This automotive shock absorber auxiliary assembly device, through the setting of fixing components, fixes the shock absorber to the position of the conveyor frame one before assembly, so that when the pushing and pressing component pushes the pressure cap onto the shock absorber for pressure assembly, the position of the shock absorber can remain unchanged, improving the docking, pressing accuracy and strength, and playing a good auxiliary role in the assembly of the shock absorber.

[0017] 3. This automotive shock absorber auxiliary assembly device, through the setting of the feeding component, when continuously assembling the shock absorber and pressure cap, when the front push frame one is conveying the shock absorber, it will simultaneously drive the actuating seat to rotate the lever and connecting rod, so that after the blocking plate opens on the feeding frame, the automotive shock absorber and pressure cap roll down from the discharge chute one and discharge chute two to the conveying frame one and conveying frame two respectively, completing the process of feeding one by one, eliminating the need for manual handling and transfer, and achieving the working effect of automatic feeding.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figures 1-12This invention provides an auxiliary assembly device for automotive shock absorbers, including an assembly table 1. A U-shaped seat 4 is fixedly installed in the middle of the top wall of the assembly table 1. A fixing component 5 is fixedly installed on the top wall of the U-shaped seat 4 to abut and fix the automotive shock absorber to be assembled to prevent slippage. A pushing and pressing component 6 is fixedly installed on the rear wall of the fixing component 5 to press and assemble the pressure cap and the shock absorber. A conveyor frame 8 for accommodating automotive shock absorbers is installed on the top wall of the assembly table 1. A conveyor frame 10 for accommodating pressure caps is fixedly installed on the top wall of the assembly table 1 and behind the conveyor frame 8. Conveying components 9 for step-by-step conveying of automotive shock absorbers and pressure caps are installed on the front and rear parts of the top wall of the assembly table 1, corresponding to the positions of the conveyor frame 8 and the conveyor frame 10. A feeding component 3 for intermittently discharging automotive shock absorbers and pressure caps is installed on the left side of the top wall of the assembly table 1, corresponding to the positions of the conveyor frame 8 and the conveyor frame 10. The feeding component 3 is fixedly connected to the conveying component 9.

[0027] In this implementation plan, the car shock absorbers and pressure caps are conveyed one by one in a step-by-step manner: through the setting of the conveying component 9, the car shock absorbers and pressure caps that fall on the first conveyor frame 8 and the second conveyor frame 10 are conveyed step by step, changing the manual handling method of transmission, which can reduce the workload and optimize the assembly progress during assembly. Intermittent feeding: When the conveying component 9 is working, it drives the feeding component 3 to start working synchronously. Whenever the conveying component 9 completes one conveying process, the feeding component 3 is linked to complete the replenishment of material, and a set of car shock absorbers and pressure caps are added to the conveying frame 1 8 and the conveying frame 2 10. Shock absorber fixing and assembly: After a set of automotive shock absorbers and pressure caps are transported to the position of the push-press assembly 6, the fixing assembly 5 first abuts and fixes the external position of the automotive shock absorber to prevent positional movement during assembly, thereby improving the docking accuracy and pressing strength of the automotive shock absorber and pressure cap. After the abutment and fixing are completed, the push-press assembly 6 pushes the pressure cap out of the conveyor frame 10 and begins to dock and press with the automotive shock absorber. After applying a certain force to the pressure cap, the assembly work is completed.

[0028] Specifically, the conveying assembly 9 includes two pusher frames 91 movably mounted on the front and rear walls of the conveying frame 8. The pusher frame 91 at the front is fixedly connected to the feeding assembly 3. Pusher frames 913 are movably mounted on both the front and rear walls of the conveying frame 10. A circular groove 911 is opened in the middle of the conveying frame 10. A connecting rod 912 is installed between the two pusher frames 913 and at the position corresponding to the circular groove 911. The connecting rod 912 is located in the inner wall of the circular groove 911 and is slidably connected. The same connecting frame 910 is fixedly installed between adjacent pusher frames 91 and pusher frames 913, so that the conveying frame 8, the conveying frame 10, the pusher frame 91, and the pusher frame 913 are in a completely smooth and continuous state.

[0029] In this implementation scheme, pusher frame 91 mainly transports the car shock absorbers on the outer wall of conveyor frame 8 one by one in a step-by-step manner, and pusher frame 913 mainly transports the pressure caps on the outer wall of conveyor frame 10 synchronously. Their transport speeds are exactly the same. Through the setting of connecting frame 910, conveyor frame 8, conveyor frame 10, pusher frame 91 and pusher frame 913 are in a completely smooth and connected state, and the pressure caps can be smoothly pushed from conveyor frame 10 to conveyor frame 8 to complete docking and assembly.

[0030] Specifically, brackets 98 are fixedly installed on the top wall of the assembly platform 1, corresponding to both sides of conveyor frame 1 8 and conveyor frame 2 10. A drive motor 94 is fixedly installed on the outer wall of the left bracket 98. The power shaft of the drive motor 94 passes through the corresponding bracket 98 through a bearing and is fixedly installed with a transmission gear 95. A rotating shaft 96 is rotatably installed on the inner side of several brackets 98. A disc 93 is fixedly installed on one end of several rotating shafts 96. An eccentric wheel 92 is fixedly installed at the center of the disc 93 through a connecting shaft. Several eccentric wheels 92 are fixedly connected to the corresponding push frame 1 91 or push frame 2 913 through a connecting shaft. A transmission gear 2 97 that meshes with the transmission gear 1 95 is fixedly installed on the outer wall of the left rotating shaft 96. A synchronous pulley 99 is fixedly installed on the other end of several rotating shafts 96 through a bearing passing through the corresponding bracket 98. The same synchronous belt is installed on the outer wall of two synchronous pulleys 99 on the same side.

[0031] In this embodiment, the drive motor 94 is mounted on the outer wall of the bracket 98 and controls the meshing and rotation of the transmission gear 1 95 and the transmission gear 2 97, thereby driving the rotating shaft 96, the disc 93 and the eccentric wheel 92 to start rotating. The transmission ratio of the transmission gear 1 95 and the transmission gear 2 97 is 3:1. Therefore, during assembly, the drive motor 94 pauses for a predetermined time every 3 revolutions. After 3 revolutions, the eccentric wheel 92 completes one revolution, driving the push frame 1 91 and the push frame 2 913 to complete the single delivery of the car shock absorber and the pressure cap. After a set of car shock absorbers and pressure caps stays in the push pressing assembly 6 for a certain period of time, the assembly work is completed.

[0032] Specifically, the feeding assembly 3 includes a feeding rack 31 fixedly installed on the top wall of the assembly table 1 by a stand. The front of the top wall of the feeding rack 31 is provided with a discharge trough 32 that matches the position of the conveyor frame 8 and is used to feed out the car shock absorber. The rear of the top wall of the feeding rack 31 is provided with a discharge trough 33 that matches the position of the conveyor frame 10 and is used to feed out the pressure cap.

[0033] In this embodiment, the discharge trough 32 and discharge trough 33 on the feeding rack 31 are used to transport the car shock absorber and the pressure cap respectively.

[0034] Specifically, a baffle plate 34 is rotatably mounted on the inner wall of the feeding rack 31 via a connecting rod 35. A lever 36 is fixedly mounted on the front end of the connecting rod 35 through a bearing and passing through the feeding rack 31. A tension spring 37 is mounted on the front wall of the feeding rack 31, and the movable end of the tension spring 37 is fixedly connected to the side wall of the lever 36.

[0035] In this embodiment, the baffle plate 34 mainly blocks the car shock absorbers and pressure caps placed on the discharge chute 1 32 and discharge chute 2 33 to prevent them from rolling off the feeder 31. It also limits the position of the lever 36, the connecting rod 35 and the baffle plate 34 together with the tension of the tension spring 37. The tension of the tension spring 37 is greater than the pressure exerted by the car shock absorbers and pressure caps on the baffle plate 34.

[0036] Specifically, a toggle seat 38 is fixedly installed on the outer wall of the front push frame 91 near the lever 36, and the toggle seat 38 is in contact with the bottom of the outer wall of the lever 36.

[0037] In this implementation plan, when the pusher frame 91 is in motion, it simultaneously drives the actuating seat 38 and the lever 36 to come into contact. Then, the lever 36 pulls the tension spring 37 open, and the lever 36 drives the connecting rod 35 and the blocking plate 34 to rotate and open, so that the car shock absorber and pressure cap fall onto the conveyor frame 8 and the conveyor frame 10 to complete the automatic feeding process.

[0038] Specifically, the fixing component 5 includes a lifting push rod 51 fixedly installed on the top wall of the U-shaped seat 4. The movable end of the lifting push rod 51 slides through the U-shaped seat 4 and is fixedly installed with a lifting seat 52. The outer wall of the lifting seat 52 is slidably connected to the inner wall of the U-shaped seat 4. Limiting grooves 53 are opened on the front wall of the U-shaped seat 4. Limiting blocks 54 fixed to the lifting seat 52 are slidably installed on the inner wall of the two limiting grooves 53. The limiting blocks 54 located at the rear are fixedly connected to the pushing and pressing component 6.

[0039] In this embodiment, the lifting push rod 51 pushes the lifting seat 52 down and slides on the inner wall of the U-shaped seat 4, and is limited by the sliding limit block 54 in the inner wall of the limit groove 53 to limit the movement path of the lifting seat 52 and prevent position deviation.

[0040] Specifically, the top wall of the lifting seat 52 is evenly provided with several mounting slots 512, and the inner wall of each mounting slot 512 is fixedly installed with abutment frame 55. The inner top wall of each abutment frame 55 is fixedly installed with abutment spring 57. The bottom end of each abutment spring 57 is fixedly installed with a sliding seat 58 that is slidably connected to the inner wall of the abutment frame 55. The outer wall of each abutment frame 55 is provided with a positioning slot 56. The inner wall of each positioning slot 56 is slidably installed with a positioning block 59 that is fixed to the corresponding sliding seat 58. The bottom wall of the sliding seat 58 located at the front is fixedly installed with a blocking seat 510, and the bottom walls of the remaining sliding seats 58 are fixedly installed with an arc-shaped locking seat 511.

[0041] In this embodiment, the lowering of the lifting seat 52 causes the abutment frame 55, abutment spring 57, sliding seat 58, blocking seat 510 and arc-shaped locking seat 511 to descend, which prioritizes fixing the outer wall and end of the car shock absorber, preventing the car shock absorber from moving or deflecting during assembly and pressure application, thus improving the assembly and docking accuracy and installation strength.

[0042] Specifically, the push-press assembly 6 includes an L-shaped lower pressing seat 61 fixedly installed on the outer wall of the rear limiting block 54, a through groove 66 opened on the rear wall of the U-shaped seat 4, a push rod 62 slidably installed on the inner wall of the through groove 66, a pressing seat 64 fixedly installed at the front end of the push rod 62, a telescopic spring 65 installed between the pressing seat 64 and the U-shaped seat 4 and sleeved on the outer wall of the push rod 62, and an inclined surface 63 opened on the outer wall of the push rod 62.

[0043] In this embodiment, when the lifting seat 52 descends, it will drive the limiting block 54 and the L-shaped lower pressure seat 61 to fall, and then contact the inclined surface 63 on the push rod 62. The push rod 62 moves into the through groove 66 and pushes the pressing seat 64 to extend the telescopic spring 65, so that the pressing seat 64 pushes the pressure cap on the second conveyor frame 10 to the first conveyor frame 8 to complete the docking with the car shock absorber, and completes the assembly work after applying a certain pressure.

[0044] Specifically, a control console 2 is installed on the left side of the assembly platform 1, and an exhaust rack 7 for conveying assembled automotive shock absorbers is installed on the top wall of the assembly platform 1 and on the right side of the conveyor rack 8.

[0045] In this embodiment, the console 2 is mainly used to control the operation of the electronic control components of the entire device. After the car shock absorber is assembled, it is transported to the outside through the discharge rack 7.

[0046] The working principle of this device is as follows: During operation, the lifting push rod 51 and drive motor 94 are electrically connected to the control console 2 via an external power supply. The car shock absorber and pressure cap to be assembled are placed on the discharge trough 32 and discharge trough 33 on the top of the feeding rack 31, respectively. The components are blocked by the baffle plate 34. The drive motor 94 is started to control the meshing and rotation of the transmission gear 1 95 and the transmission gear 2 97. The transmission ratio of the transmission gear 1 95 and the transmission gear 2 97 is 3:1. As the transmission gear 2 97 drives the rotating shaft 96 to rotate, the left synchronous wheel 99 is synchronously controlled to rotate. Under the transmission of the synchronous belt, the right synchronous wheel 99 is driven to rotate, so that the synchronous wheels 99 on both sides and the rotating shaft 96 simultaneously drive the disc 93 and the eccentric wheel 92 to start rotating at a uniform speed. The eccentric wheel 92 at the front drives the corresponding pusher frame 91 to start step feeding. The rear conveying assembly 9 drives the pusher frame 913 to move along the outer wall of the conveyor frame 10. When the rear pusher frame 913 drives the connecting rod 912 to move inside the circular groove 911, the other pusher frame 913 drives the rear pusher frame 91 to move at the same speed through the connection of the connecting frame 910. Driven by the conveying assembly 9, the pusher frame 91 moves along the outer wall of the conveyor frame 8, and the pusher frame 913 moves along the outer wall of the conveyor frame 10. When the front push frame 91 moves along the rotation path of the eccentric wheel 92, it will drive the actuating seat 38 to move. When the actuating seat 38 moves, it will drive the lever 36 and the connecting rod 35 to rotate. The lever 36 drives the tension spring 37 to stretch and at the same time drives the baffle plate 34 to rotate and open outward inside the feeding frame 31, so that the car shock absorbers and pressure caps placed in the discharge trough 32 and discharge trough 33 respectively fall and are discharged onto the conveying frame 8 and the conveying frame 10. The push frame 91 will transport the car shock absorbers that fall on the outer wall of the conveying frame 8 step by step, and the push frame 913 will transport the pressure caps that fall on the outer wall of the conveying frame 10 at the same speed. After the car shock absorber and pressure cap are synchronously conveyed to the bottom of the U-shaped seat 4, since the transmission ratio of transmission gear 1 95 and transmission gear 2 97 is 3:1, the drive motor 94 is precisely controlled to rotate a certain number of revolutions. The drive motor 94 stops working for a certain period of time after every 3 revolutions (to reserve assembly time, the specific time can be set through the control console 2 after assembly testing). At the same time, after every 3 revolutions of transmission gear 1 95, it drives transmission gear 2 97 to rotate a full revolution, which causes the rotating shaft 96 to drive the disc 93 and the eccentric wheel 92 to rotate a full revolution, thereby enabling the push frame 1 91 and push frame 2 913 to complete the step-by-step single conveying of the car shock absorber and pressure cap. After the car shock absorber and pressure cap are delivered directly below the U-shaped seat 4, the lifting push rod 51 pushes the lifting seat 52 to descend inside the U-shaped seat 4. This causes the lifting seat 52 to move the limiting block 54 downward along the inner wall of the limiting groove 53. Simultaneously, the abutment frame 55 installed inside the mounting groove 512 on the top wall of the lifting seat 52 is pushed down. The abutment frame 55 drives the abutment spring 57, sliding seat 58, blocking seat 510, and arc-shaped locking seat 511 to descend. The outer wall of the blocking seat 510 abuts the front end of the car shock absorber. Next, the outer wall position of the car shock absorber is locked and limited by the arc-shaped locking seat 511. As the lifting seat 52 continues to descend, the blocking seat 510 and the arc-shaped locking seat 511 drive the corresponding sliding seat 58 into the interior of the abutment frame 55 to compress the abutment spring 57. At the same time, the sliding seat 58 drives the positioning block 59 to slide in the inner wall of the corresponding positioning groove 56. Under the elastic action of the abutment spring 57, the outer and end positions of the car shock absorber are locked and limited to prevent movement and displacement during assembly. After the limiting block 54 descends, it drives the L-shaped lower pressure seat 61 to move down gradually. As the L-shaped lower pressure seat 61 moves down, it contacts the inclined surface 63 opened at the top of the push rod 62 and gradually pushes the push rod 62 and the pressing seat 64 through the push frame 2 913 to push the pressure cap conveyed on the conveyor frame 2 10. At this time, the telescopic spring 65 is in a stretched state. After passing through the connecting frame 910, it docks and presses with the end of the car shock absorber. The push rod 62 pushes the pressing seat 64 to apply force to the pressure cap and the end of the car shock absorber, completing the auxiliary assembly of the car shock absorber. After assembly is completed, the retraction of the movable end of the lifting push rod 51 causes the lifting seat 52 to rise. Through the limit block 54, the L-shaped lower pressure seat 61 is disengaged from the inclined surface 63. At this time, the extension spring 65 retracts, causing the pressing seat 64 and the push rod 62 to return to their original positions. At the same time, the blocking seat 510 and the arc-shaped locking seat 511 disengage from the car shock absorber. Then the conveying component 9 starts to work again to convey the unassembled and assembled car shock absorbers. The assembled car shock absorber is discharged to the outside after passing through the discharge rack 7. When assisting in the assembly of pressure caps and automotive shock absorbers, this device feeds the pressure cap components and automotive shock absorbers one by one in a step-by-step conveying manner. During the feeding process, the feeding component 3 moves synchronously and automatically unloads the materials, so that the pressure caps and automotive shock absorbers fall onto the first conveyor frame 8 and the second conveyor frame 10, respectively. After being conveyed to the bottom of the fixed component 5, they stay for a predetermined time and are then assembled by the pushing and pressing component 6.
