Description

Technical Field

[0001] This invention relates to the field of automobile assembly technology, specifically to an automobile shock absorber assembly device and assembly method. Background Technology

[0002] Shock absorbers are used to suppress the impact of the rebound after the spring absorbs the shock. A shock absorber is composed of a spring and a shock absorber rod. The shock absorber is not used to support the weight of the equipment, but to suppress the rebound after the spring absorbs the shock and absorb the energy of the impact. The spring plays the role of buffering the impact.

[0003] In traditional shock absorber assembly, after the spring is placed, the threaded portion of the shock absorber main rod is covered. When installing the nut, manual compression of the spring is required to expose the threads before the nut can be installed. This method is tiring and difficult to operate manually. A targeted improvement device has been developed, as shown in the published patent (patent number: CN202210842834.1, patent title: An Assembly Device for Manufacturing Automotive Shock Absorbers). This patent uses multiple motors to replace the traditional manual assembly method. However, to put this patent into practical application... In practical use, even the simple process of installing a nut onto a socket wrench requires the coordination of multiple motors. This means that each use must be timed precisely to ensure the nut is correctly fed into the socket wrench. Therefore, if this solution is to meet the long-term assembly line requirements and ensure the nut is correctly and reliably placed into the socket wrench, additional programming is needed to ensure proper coordination between the multiple motors. This increases unnecessary costs, making the project inconvenient in practice and requiring further improvement in the overall assembly efficiency of the shock absorber assembly.

[0016] Optionally, a reset cylinder is fixedly connected to the surface of the insertion cylinder, and the end of the reset cylinder is fixedly connected to the surface of the mating cylinder.

[0017] This invention also provides a method for assembling an automotive shock absorber assembly, comprising the following steps:

[0018] S1: Preliminary preparation: Place the assembly to be assembled into the insertion cylinder on the housing, and pre-fill the nut plate with a large number of nuts. When using it for the first time, initially insert a nut into the groove on the loading plate, then start the reset cylinder to make the insertion cylinder slide along the inner wall of the housing. After the displacement is completed, stop the drive of the reset cylinder and maintain this position.

[0019] S2: Start assembly: First, start the motor to drive the loading plate to move in a U-shape. At the same time, as the loading plate moves up, the nut is gradually pushed out of the groove, so that the nut is efficiently locked into the socket wrench. Then, start the cylinder group to drive the motor, the extrusion assembly and the socket wrench to move down, extruding and installing the spring in the assembly. At the same time, when the socket wrench contacts the piston rod on the assembly, the rotation of the socket wrench driven by the motor can install the nut on the piston rod on the assembly.

[0020] S3: Automatic feeding: When the feeding plate moves vertically downward to reset, the nut disc will deflect once, causing a nut in a nut sleeve to fall from the feeding port, pass through the telescopic cylinder and fall into the groove on the feeding plate, completing the automatic feeding process.

[0021] S4: Reset Inspection: When all assemblies on the production line are assembled, the reset cylinder can be driven to move the mating cylinder away from the insertion cylinder, allowing the nut disc to rotate in any direction. Personnel can easily perform supplementary inspections on the nuts on the nut disc as needed, facilitating periodic material replenishment or convenient maintenance of the socket wrench area, thus comprehensively improving the practical efficiency of the device.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] I. This invention, through the cooperation of structures such as a fixed axis, a displacement groove, and a displacement frame, enables the feeding plate to perform a U-shaped displacement, thereby allowing the nut to be efficiently engaged into the socket wrench. Compared with the traditional method, this method is more efficient in installing nuts, requiring only one drive. Furthermore, after the nut is engaged into the socket wrench, the feeding plate directly disengages, rather than moving downwards first and then disengaging. This further avoids the influence of groove friction on the nut's disengagement, further ensuring assembly efficiency.

[0024] Second, the present invention firstly ensures that the nut will not be misaligned due to the friction between the two when it is transferred by the feeding plate, thus avoiding the situation where the structure gets stuck when the socket wrench is inserted laterally.

[0025] Secondly, through the cooperation of the magnet, shaft and rod, when the feeding plate moves up and inserts the nut into the socket wrench, it can make contact with the socket wrench more quickly and be inserted more thoroughly, thereby further ensuring the installation efficiency of nut feeding and improving the assembly efficiency of the assembly from the perspective of ensuring feeding quality.

[0026] Third, through the cooperation of structures such as triangular toothed plates, ratchet plates and gears, the nut disc will deflect once, so that the next nut falls into the groove on the loading plate, thereby realizing automatic material replenishment and preparing for the assembly of the next assembly, further improving assembly efficiency.

[0027] Fourth, through the cooperation of the drive shaft, mating groove and mating cylinder, etc., the present invention enables personnel to easily replenish and inspect the nuts on the nut plate as needed after multiple assemblies are assembled, without having to rotate in a fixed direction and overcome certain structural resistance, which facilitates personnel to replenish materials periodically.

[0028] Furthermore, since there are no nut discs or other components in the area where the socket wrench is located, it is convenient to inspect and maintain the socket wrench area, thus comprehensively improving the practical efficiency of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0046] Please see Figures 1 to 15 The present invention provides an assembly device for an automobile shock absorber assembly, including a housing 1 and an assembly 2, and also includes a body 3. A cylinder group 4 is fixedly connected to the inner wall of the housing 1, a motor 5 is fixedly connected to the surface of the cylinder group 4, a socket wrench 6 is fixedly connected to the output end of the motor 5, a pressing component 7 is fixedly connected to the outer wall of the motor 5, and an insertion cylinder 8 is provided inside the housing 1 for the assembly 2 to be inserted.

[0047] A nut disc 9 is provided on the top of the main body 3, and a feeding plate 10 is provided at the front of the main body 3. A displacement plate 11 is fixedly connected to the surface of the feeding plate 10. A groove is opened on the surface of the feeding plate 10, and a push plate 12 is slidably connected to the inner wall of the groove. A mating cylinder 13 is fixedly connected to the bottom surface of the main body 3. The mating cylinder 13 is slidably connected to the inner wall of the outer shell 1. It also includes two sets of feeding components, one set of unloading components, auxiliary components, switching components, mating components, and two sets of driving components. Both sets of feeding components are located inside the main body 3. The auxiliary components are drivenly connected to the two sets of feeding components, and the switching components are drivenly connected to both sets of feeding components.

[0048] The feeding component includes a main shaft 14, a disc 15 fixedly connected to the shaft wall of the main shaft 14, a displacement groove 16 opened on the side wall of the disc 15, the displacement groove 16 includes a connecting groove and an arc groove, a fan-shaped plate 17 fixedly connected to the shaft wall of the main shaft 14, a limit rod assembly 18 slidably connected to the inner wall of the body 3, a displacement frame 19 slidably connected to the rod wall of the limit rod assembly 18, a fixed shaft 20 slidably connected to the groove wall of the displacement groove 16, a displacement port for the fixed shaft 20 to move on the surface of the displacement frame 19, the end of the fixed shaft 20 is fixedly connected to the surface of the displacement plate 11, and the displacement plate 11 is slidably connected to the inner wall of the body 3.

[0049] The feeding component includes a telescopic cylinder 21, a rotating shaft 22 rotatably connected to the inner wall of the main body 3, a polygonal groove opened on the inner wall of the rotating shaft 22, a rotating shaft 23 sleeved on the inner wall of the rotating shaft 22, a polygonal block 24 corresponding to the polygonal groove fixedly connected to the shaft wall of the rotating shaft 23, a fixed plate 25 fixedly connected to the top surface of the main body 3, the shaft wall of the rotating shaft 23 rotatably connected to the inner wall of the fixed plate 25, the end of the rotating shaft 23 fixedly connected to the surface of the nut plate 9, a feeding port opened on the surface of the fixed plate 25, the telescopic cylinder 21 fixedly connected to the feeding port on the bottom surface of the fixed plate 25, and the nut plate 9 includes five nut sleeves;

[0050] The driving component includes a motor 41, which is fixedly connected to the inner wall of the main body 3. The output end of the motor 41 is fixedly connected to the end of the main shaft 14. A reset cylinder 42 is fixedly connected to the surface of the insertion cylinder 8, and the end of the reset cylinder 42 is fixedly connected to the surface of the mating cylinder 13.

[0051] More specifically, in this embodiment: when starting use and needing to assemble assembly 2, the assembly 2 to be assembled is placed in the insertion cylinder 8 on the outer casing 1, and a large number of nuts are pre-filled into the nut disc 9. An initial nut is placed into the groove on the upper feed plate 10. Then, the reset cylinder 42 is activated, causing the insertion cylinder 8 to slide along the inner wall of the outer casing 1. This moves the components above it closer to the socket wrench 6. After the components have moved closer, the drive of the reset cylinder 42 is stopped, and the cylinder remains in this position. Then, the first assembly begins. During assembly, two buttons can be installed on the outer casing 1. One button controls motor 41, and the other controls cylinder group 4 and motor 5. First, motor 41 is started. Taking the drive of a single motor 41 as an example, it drives the main shaft 14 to rotate one revolution. The rotation of the main shaft 14 causes the disk 15 to rotate, thus causing the displacement groove 16 to move in a circular motion. At this time, the fixed shaft 20 slides along the groove wall of the displacement groove 16. Simultaneously, the rotation of the main shaft 14 also causes the sector plate 17 to rotate. When the main shaft 14 initially rotates, the fixed shaft 20 first slides into the displacement groove along with the movement of the displacement groove 16. At the connecting groove on 16, the fixed shaft 20 moves towards the assembly 2. During this movement, the arc edge of the sector plate 17 contacts the inner wall of the displacement frame 19. That is, the rotation of the sector plate 17 is due to its arc edge sliding along the inner wall of the displacement frame 19. At this time, the vertical position of the displacement frame 19 remains unchanged. The displacement of the fixed shaft 20 will drive the displacement plate 11 to move synchronously. Through the transmission of the displacement plate 11, the feeding plate 10 carrying the nut can move closer to the socket wrench 6. When the fixed shaft 20 slides out of the connecting groove into the arc groove, the disc... As 15 continues to rotate, the horizontal position of the fixed shaft 20 remains unchanged. At this time, the arc edge of the sector plate 17 disengages from the inner wall of the displacement frame 19. The continued rotation of the sector plate 17 will push the displacement frame 19 to move vertically upward under the limit of the limit rod group 18. Through the vertical upward movement of the displacement frame 19, the fixed shaft 20, the displacement plate 11, and the feeding plate 10 can be moved vertically upward. During this process, the fixed shaft 20 slides along the arc groove on the displacement groove 16 and will not disengage from the displacement groove 16. Through the vertical upward movement of the feeding plate 10, the nut can be inserted into the socket wrench 6.

[0052] At this time, the main shaft 14 completes a 180° rotation. Then, as the main shaft 14 continues to rotate, the fixed shaft 20 will slide from the arc groove on the displacement groove 16 into the connecting groove again. During this process, the arc edge of the fan-shaped plate 17 slides along the inner wall of the displacement frame 19 again, that is, the vertical height of the displacement frame 19 remains unchanged until its arc edge separates from the inner wall of the displacement frame 19. Then, its rotation pushes the displacement frame 19 to move vertically downward. At this time, the fixed shaft 20 slides from the connecting groove into the arc groove again. In this way, as the main shaft 14 rotates one revolution, the feeding plate 10 can be driven to perform a displacement with a U-shaped feature.

[0053] After the nut is inserted into the socket wrench 6, the cylinder assembly 4 is activated, driving the motor 5, the pressing assembly 7, and the socket wrench 6 to move downwards. The downward movement of the pressing assembly 7 compresses and installs the spring in the assembly 2. At the same time, when the socket wrench 6 contacts the piston rod on the assembly 2, the rotation of the socket wrench 6 driven by the motor 5 can install the nut on the piston rod on the assembly 2. This process can be regarded as prior art, and the detailed process will not be described in detail.

[0054] The displacement with a U-shaped feature made by the feeding plate 10 allows the nut to be efficiently engaged into the socket wrench 6. Compared with the traditional method, this method is more efficient in installing the nut, requiring only one drive. At the same time, after the nut is engaged into the socket wrench 6, the feeding plate 10 is directly disengaged, rather than moving downwards first and then disengaging. This further avoids the influence of groove friction on the nut disengagement, further ensuring assembly efficiency.

[0055] Example 2, based on the above examples:

[0056] Please see Figures 3 to 14 The auxiliary components include two magnets 26, which are slidably connected to the inner wall of the main body 3. The surface of the displacement plate 11 has slots corresponding to the two magnets 26. A rod 27 is slidably connected to the inner wall of the displacement plate 11. Both ends of the rod 27 are fixedly connected to magnets 28 that repel the two magnets 26 respectively. A shaft 29 is fixedly connected to the rod wall of the rod 27. The shaft 29 extends into the feeding plate 10. The shaft wall of the shaft 29 is fixedly connected to the inner wall of the push plate 12.

[0057] More specifically, in this embodiment: during the process of the feeding plate 10 performing a U-shaped displacement, when it first moves closer to the socket wrench 6, the displacement of the displacement plate 11 will cause the two magnets 26 to be inserted into the socket. During the process of the magnets 26 being inserted into the socket, the repulsive force between the magnets 26 and the second magnet 28 will cause the rod 27 connected to the second magnet 28 to move upward gradually with the displacement of the displacement plate 11. By moving the rod 27 upward within the displacement plate 11, the shaft 29 can be moved upward, so that when the push plate 12 moves closer to the socket wrench 6 with the displacement plate 11, the push plate 12 moves upward gradually. By moving the push plate 12 upward, the nut can be gradually pushed out of the groove. When the nut is moved to directly below the socket wrench 6, the nut is completely pushed out.

[0058] Through this process, firstly, the groove ensures that the nut will not be misaligned due to the friction between the nut and the feed plate 10 during the transfer, thus preventing the nut from getting stuck when it is subsequently inserted into the socket wrench 6. At the same time, when the feed plate 10 moves upward and inserts the nut into the socket wrench 6, it can make contact with the socket wrench 6 more quickly, making it more thoroughly inserted. This further ensures the installation efficiency of the nut feeding process and improves the assembly efficiency of the assembly 2 from the perspective of ensuring feeding quality. Since the nut is supported upward by the feed plate 10 during this process, the groove is not required and the two will not be misaligned.

[0059] Example 3, based on the above examples:

[0060] Please see Figures 3 to 15 The switching components include: two fixed plates 30, the shaft walls of the two main shafts 14 are rotatably connected to the inner walls of the two fixed plates 30, the surfaces of the two fixed plates 30 are slidably connected with triangular toothed plates 31, the shaft wall of the rotating shaft 22 is fixedly connected with a gear 32, the teeth of the two triangular toothed plates 31 mesh with the teeth of the gear 32, the ends of the two triangular toothed plates 31 are hinged with hinge rods 33, and the ends of the two hinge rods 33 are respectively hinged to the surfaces of the two displacement frames 19;

[0061] A ratchet plate 34 is fixedly connected to the shaft wall of the rotating shaft 22, and a spring 35 is fixedly connected to the inner wall of the body 3. A retaining plate 36 is fixedly connected to the end of the spring 35, and the end of the retaining plate 36 is rotatably connected to the inner wall of the body 3.

[0062] More specifically, in this embodiment: when the displacement frame 19 moves vertically upward, the hinge rod 33 drives the triangular toothed plate 31 to slide on the surface of the fixed plate 30. At this time, the inclined surface of the triangular teeth of the triangular toothed plate 31 abuts against the gear 32. Therefore, the displacement of the triangular toothed plate 31 will only cause the triangular teeth on it to be continuously squeezed, without driving the gear 32 to rotate. In this process, the clamping plate 36 and ratchet plate 34 below the structure also further ensure this purpose by ensuring that the rotating shaft 22 rotates in a single direction. When the displacement frame 19 moves vertically downward, the straight surface of the triangular teeth contacts the gear 32. At this time, the hinge rod 33 drives the triangular toothed plate 31 to slide on the surface of the fixed plate 30. The displacement of the triangular toothed plate 31 will cause the gear 32 to rotate. The rotation of the gear 32 will cause the rotating shaft 22 to rotate. During this process, the inclined surface of the ratchet plate 34 cooperates with the clamping plate 36, that is, the clamping plate 36 is continuously compressed, deflected and reset. Through the rotation of the rotating shaft 22, through the cooperation of the polygonal groove and the polygonal block 24, the rotating shaft 23 will rotate synchronously. Through the rotation of the rotating shaft 23, the nut disc 9 will deflect. During the deflection of the nut disc 9, the nut in one of the nut sleeves will fall from the feeding port, pass through the telescopic cylinder 21 and fall into the groove on the feeding plate 10, completing the automatic replenishment of the nut.

[0063] It is worth noting that when the feed plate 10 is feeding, the telescopic cylinder 21 is compressed. When it moves away from the socket wrench 6, it moves along the end of the telescopic cylinder 21. When it moves downward, half of the downward path causes the nut to fall from the telescopic cylinder 21 into the groove. In this state, the end of the telescopic cylinder 21 is still in contact with the surface of the feed plate 10, that is, the nut will not fall to other places. In the latter half of its downward path, the feed plate 10 is separated from the lower end of the telescopic cylinder 21. Thus, the setting of the telescopic cylinder 21 can ensure the accuracy of feeding.

[0064] By adopting the above method, after each pair of assemblies 2 is fitted with a nut, the nut disc 9 will deflect once, so that the next nut falls into the groove on the feed plate 10, thereby realizing automatic material replenishment and preparing for the assembly of the next assembly 2, further improving assembly efficiency.

[0065] Example 4, based on the above examples:

[0066] Please see Figures 2 to 15 The mating components include: a connecting sleeve 37, which is rotatably connected to the shaft wall of the rotating shaft 23; two drive shafts 38 are fixedly connected to the surface of the connecting sleeve 37; both sides of the mating cylinder 13 are provided with through holes for displacement of the drive shafts 38; two baffles 39 are fixedly connected to the surface of the outer shell 1; mating grooves 40 are fixedly connected to the opposite sides of the two baffles 39; the mating grooves 40 include straight grooves and inclined grooves; and the shaft walls of the two drive shafts 38 are slidably connected to the groove walls of the two mating grooves 40 respectively.

[0067] More specifically, in this embodiment: when all assemblies 2 on the production line are assembled, the reset cylinder 42 can be driven to move the mating cylinder 13 away from the insertion cylinder 8. At this time, the two drive shafts 38 slide along the straight grooves on the two mating grooves 40 respectively. When the mating cylinder 13 moves to the end, the drive shafts 38 are displaced to slide along the inclined grooves on the mating grooves 40, so that the two drive shafts 38 move vertically upward, thereby causing the connecting sleeve 37 to move vertically, and then causing the rotating shaft 23 to move vertically. The vertical movement of the rotating shaft 23 causes it to disengage from the polygonal slot, thus losing the limit position that is consistent with the rotating shaft 22. In this state, the nut disc 9 can rotate in any direction. After the device is used up, personnel can easily perform supplementary inspections on the nuts on the nut disc 9 as needed, without having to rotate in a fixed direction and overcome certain structural resistance. This facilitates periodic material replenishment, or facilitates maintenance of the socket wrench 6 area since there are no components such as the nut disc 9. This comprehensively improves the practical efficiency of the device.

[0068] Please see Figures 1 to 16 The present invention provides a method for assembling an automotive shock absorber assembly as follows:

[0069] The assembly to be assembled, 2, is placed inside the insertion cylinder 8 on the housing 1. A large number of nuts are pre-filled into the nut disc 9. An initial nut is inserted into the groove on the upper plate 10. Then, the reset cylinder 42 is activated, causing the insertion cylinder 8 to slide along the inner wall of the housing 1. This moves the components above it closer to the socket wrench 6. Once the components are close, the reset cylinder 42 is stopped, and the cylinder remains in this position. Assembly then begins. Two buttons can be installed on the housing 1 during assembly: one to control the motor 41 and the other to control the cylinder assembly 4. And motor 5, at this time, motor 41 is started first, driving the main shaft 14 to rotate one revolution, thereby driving the feeding plate 10 to make a displacement with a U-shaped feature, so that the nut is efficiently locked into the socket wrench 6. Then, the cylinder group 4 is started, driving motor 5, extrusion assembly 7 and socket wrench 6 to move down. Through the downward movement of extrusion assembly 7, the spring in assembly 2 is extruded and installed. At the same time, when socket wrench 6 contacts the piston rod on assembly 2, the rotation of socket wrench 6 driven by motor 5 can install the nut on the piston rod on assembly 2.

[0070] When the feeding plate 10 moves closer to the socket wrench 6, the push plate 12 moves closer to the socket wrench 6 and gradually moves upwards, following the displacement plate 11. By moving the push plate 12 upwards, the nut can be gradually pushed out of the groove. When the nut moves to the bottom of the socket wrench 6, the nut is completely pushed out. When the feeding plate 10 moves vertically downwards to reset, the nut disc 9 will deflect once, causing a nut in the nut sleeve to fall from the feeding port and fall into the groove on the feeding plate 10 through the telescopic cylinder 21, completing the automatic nut replenishment process.

[0071] When all assemblies 2 on the production line are assembled, the reset cylinder 42 can be driven to move the mating cylinder 13 away from the insertion cylinder 8. This causes the rotating shaft 23 to lose its limit position consistent with the rotating shaft 22 after the device is used, allowing the nut disc 9 to rotate in any direction. After the device is used, personnel can easily replenish and inspect the nuts on the nut disc 9 as needed without having to rotate in one direction and overcome certain structural resistance. This facilitates periodic replenishment of materials, or, since there is no nut disc 9 light element in the socket wrench 6 area, it is convenient to inspect the socket wrench 6 area, thus comprehensively improving the practical efficiency of the device.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
