Description

Technical Field

[0001] The invention relates to the technical field of automobile assembly, in particular to an automobile shock absorber assembly assembly device and an assembly method. Background Art

[0002] The shock absorber is used to suppress the shock when the spring rebounds after absorbing shock. The shock absorber is composed of a spring and a shock-absorbing main rod. The shock absorber is not used to support the weight of the equipment, but to suppress the shock when the spring rebounds after absorbing shock and absorb the impact energy. The spring plays a role in alleviating the impact;

[0003] During the assembly process of traditional shock absorbers, after the spring is placed, the threaded part on the shock absorber main rod will be covered. At this time, when installing the nut, the personnel need to manually compress the spring to expose the thread and then install the nut. This method is easy to cause fatigue and difficult to operate. There is now a targeted improved device, such as a published patent, patent number: CN202210842834.1, patent name: An assembly device for producing automobile shock absorbers. In this patent, the cooperation of multiple motors replaces the traditional method of manual assembly, but if this patent is to be put into practice In actual use, the process of installing the nut on the "socket wrench" alone requires the coordination of multiple motors, that is, the timing must be grasped each time it is used to ensure that there are no errors in the process of loading the nut into the "socket wrench". Therefore, if this solution wants to meet the long-term assembly goals of the assembly line and ensure that the nut is placed in the "socket wrench" without any difference and quality, it is necessary to add additional program design to ensure that multiple motors achieve good coordination timing, which increases unnecessary costs. Therefore, the actual use of this project is still inconvenient, and there is room for improvement in comprehensively improving the assembly efficiency of the shock absorber assembly.

[0017] The present invention also provides the following automobile shock absorber assembly assembly method, comprising the following steps:

[0018] S1: Preliminary preparation: Place the assembly to be assembled in the insertion cylinder on the housing, and add a large number of nuts to the nut plate in advance. When used for the first time, initially put a nut into the groove on the upper plate, and then start the reset cylinder to make the insertion cylinder slide along the inner wall of the housing. After the displacement is completed, stop driving the reset cylinder and maintain this position;

[0019] S2: Start assembly: First start the motor to drive the feeding plate to perform a displacement with a U-shaped feature. At the same time, in the process of the feeding plate moving up, the nut is gradually pushed out from the groove, so that the nut is efficiently stuck in the socket wrench. Then start the cylinder group to drive the motor, the extrusion assembly and the socket wrench to move down, and the spring in the assembly is extruded and installed. 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 refilling: When the loading plate is vertically moved downward to reset, the nut plate will produce a self-deflection, so that the nut in a nut sleeve will fall from the loading port, pass through the telescopic tube and fall into the groove on the loading plate, completing the automatic refilling process of the nut;

[0021] S4: Reset inspection: When all assemblies on the production line are assembled, the reset cylinder can be driven to move the matching cylinder away from the insertion cylinder, so that the nut plate can be rotated in any direction. The personnel can easily perform additional inspections on the nuts on the nut plate as needed, which is convenient for periodic material replenishment or convenient maintenance of the socket wrench area, comprehensively improving the practical efficiency of the device.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention achieves a displacement with a U-shaped characteristic by cooperating with structures such as a fixed axis, a displacement groove and a displacement frame, so that the nut can be efficiently inserted into the socket wrench. Compared with the traditional method, this method is more efficient in installing the nut and only requires one drive. At the same time, after the nut is inserted into the socket wrench, the loading plate is directly disengaged instead of first moving down and then disengaging. This can further avoid the influence of the friction of the groove on the disengagement of the nut, thereby further ensuring the assembly efficiency.

[0024] Second, the present invention firstly provides a groove so that when the nut is transferred by the feeding plate, it will not be misplaced due to the friction between the two caused by the lateral movement, thereby avoiding the situation that the structure is stuck when it is subsequently inserted into the socket wrench;

[0025] Secondly, through the cooperation of the magnet, the shaft and the rod structure, when the loading plate is immediately moved up to clamp the nut into the socket wrench, it can contact the socket wrench faster and be clamped more thoroughly, thereby further ensuring the installation efficiency of the nut loading and further improving the assembly efficiency of the assembly from the perspective of ensuring the loading quality.

[0026] 3. Through the coordination of the triangular tooth plate, ratchet plate and gear and other structures, the nut plate will produce a deflection, so that the next nut falls into the groove on the feeding plate, thereby realizing automatic material replenishment, preparing for the assembly of the next assembly, and further improving the assembly efficiency.

[0027] Fourth, the present invention cooperates with the transmission shaft, the matching groove and the matching cylinder, so that after the assembly of multiple assemblies is completed, the personnel can easily perform supplementary inspections on the nuts on the nut plate as needed, without the need to rotate in a fixed direction and overcome certain structural resistance, which is convenient for personnel to perform periodic feeding;

[0028] Furthermore, since there are no components such as nut plates in the area where the socket wrench is located, it is convenient to inspect and repair the socket wrench area, thereby comprehensively improving the practical efficiency of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The feeding component includes a main shaft 14, a disk 15 is fixedly connected to the shaft wall of the main shaft 14, a displacement groove 16 is provided on the side wall of the disk 15, and the displacement groove 16 includes a connecting groove and an arc groove, a fan-shaped plate 17 is fixedly connected to the shaft wall of the main shaft 14, a limiting rod group 18 is slidably connected to the inner wall of the body 3, a displacement frame 19 is slidably connected to the rod wall of the limiting rod group 18, a fixed shaft 20 is slidably connected to the groove wall of the displacement groove 16, a displacement opening for displacement of the fixed shaft 20 is provided on the surface of the displacement frame 19, an 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;

[0050] The unloading component includes a telescopic cylinder 21, the inner wall of the body 3 is rotatably connected with a rotating shaft 1 22, the inner wall of the rotating shaft 1 22 is provided with a polygonal groove, the inner wall of the rotating shaft 1 22 is sleeved with a rotating shaft 23, the shaft wall of the rotating shaft 23 is fixedly connected with a polygonal block 24 corresponding to the polygonal groove, the top surface of the body 3 is fixedly connected with a fixed disk 25, the shaft wall of the rotating shaft 23 is rotatably connected to the inner wall of the fixed disk 25, the end of the rotating shaft 23 is fixedly connected to the surface of the nut disk 9, the surface of the fixed disk 25 is provided with a loading port, the telescopic cylinder 21 is fixedly connected to the loading port on the bottom surface of the fixed disk 25, and the nut disk 9 includes five nut sleeves;

[0051] 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. The surface of the inserted tube 8 is fixedly connected with a reset cylinder 42, and the end of the reset cylinder 42 is fixedly connected to the surface of the matching tube 13.

[0052] More specifically, in this embodiment: when the assembly 2 is to be assembled at the beginning of use, the assembly 2 to be assembled is placed in the insertion tube 8 on the housing 1, and a large number of nuts are pre-filled in the nut plate 9, and a nut is initially placed in the groove on the upper plate 10, and then the reset cylinder 42 is started, so that the insertion tube 8 slides along the inner wall of the housing 1, and at this time, the component above it is driven to approach the socket wrench 6. After the approach is completed, the drive of the reset cylinder 42 is stopped, and this position is maintained, and then an assembly is started. During assembly, two buttons can be set on the housing 1. The first button is used to control the motor 41, and the second button is used to control the cylinder group 4 and the motor 5. At this time, the motor 41 is started first, and the driving of a single motor 41 in the structure is described as an example, driving the main shaft 14 to rotate one circle. The rotation of the main shaft 14 can make the disk 15 rotate, so that the displacement groove 16 can move in a circular motion. At this time, the fixed shaft 20 slides along the groove wall of the displacement groove 16. At the same time, the rotation of the main shaft 14 will also make the fan-shaped plate 17 rotate. When the main shaft 14 initially rotates, the fixed shaft 20 first slides to the displacement groove along with the movement of the displacement groove 16. 16, at this time, the fixed shaft 20 is displaced in the direction close to the assembly 2. During this displacement process, the arc edge of the sector plate 17 contacts the inner wall of the displacement frame 19, that is, the rotation process of the sector plate 17 is that its arc edge slides along the inner wall of the displacement frame 19, that is, at this time, the vertical position of the displacement frame 19 remains unchanged, and 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 can carry the nut to the direction of the socket wrench 6. When the fixed shaft 20 slides out of the connecting groove to the arc groove, at this time, as the disc 15 continues to rotate, at this time the horizontal position of the fixed shaft 20 remains unchanged, and at this time the arc edge of the sector plate 17 is separated from the inner wall of the displacement frame 19, and at this time 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, and the fixed shaft 20, the displacement plate 11, and the loading plate 10 can be moved vertically upward by the vertical movement of the displacement frame 19. In this process, the fixed shaft 20 slides along the arc groove on the displacement groove 16 and will not be separated from the displacement groove 16. By moving the loading plate 10 vertically upward, the carried nut can be stuck in the socket wrench 6;

[0053] At this time, the main shaft 14 completes a 180° rotation, and 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 sector 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 is separated from the inner wall of the displacement frame 19, and its rotation pushes the displacement frame 19 to move vertically downward, and at this time, the fixed shaft 20 slides from the connecting groove into the arc groove again, so that as the main shaft 14 rotates one circle, the loading plate 10 can be driven to perform a displacement with a U-shaped characteristic;

[0054] After the nut is inserted into the socket wrench 6, the cylinder group 4 is started to drive the motor 5, the extrusion assembly 7 and the socket wrench 6 to move downward. By moving the extrusion assembly 7 downward, the spring in the assembly 2 is extruded and installed. 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 a prior art and the detailed process will not be repeated.

[0055] In this way, the U-shaped displacement of the loading plate 10 allows the nut to be efficiently inserted into the socket wrench 6. That is, compared with the traditional method, this method is more efficient in installing the nut and only requires one drive. At the same time, after the nut is inserted into the socket wrench 6, the loading plate 10 is directly disengaged instead of moving down first and then disengaging. This can further avoid the influence of the friction of the groove on the disengagement of the nut, thereby further ensuring the assembly efficiency.

[0056] Embodiment 2, based on the above embodiment:

[0057] See also Figures 3 to 14 The auxiliary components include two magnets 26, which are slidably connected to the inner wall of the body 3. The surface of the displacement plate 11 is provided with sockets corresponding to the two magnets 26. The inner wall of the displacement plate 11 is slidably connected with a rod 27, and both ends of the rod 27 are fixedly connected with magnets 28 that repel the two magnets 26 respectively. The rod wall of the rod 27 is fixedly connected with a shaft 29, and the shaft 29 extends into the loading plate 10. The shaft wall of the shaft 29 is fixedly connected to the inner wall of the push plate 12.

[0058] More specifically, in this embodiment: during the U-shaped displacement of the above-mentioned feeding plate 10, when it first approaches the direction of the socket wrench 6, the displacement of the displacement plate 11 at this time will cause the two magnets 1 26 to be inserted into the socket. During the insertion of the magnet 1 26 into the socket, the repulsive force between the magnet 1 26 and the magnet 2 28 will cause the rod 27 connected to the magnet 2 28 to gradually move upward along with the displacement of the displacement plate 11. By the upward movement of the rod 27 in the displacement plate 11, the shaft 29 can be moved upward, so that when the push plate 12 follows the displacement plate 11 to move closer to the socket wrench 6, the push plate 12 gradually moves upward. By the upward movement of the push plate 12, the nut can be gradually pushed out from the groove. When the nut is displaced to just below the socket wrench 6, the nut is completely pushed out.

[0059] Through this process, firstly, by opening the groove, the nut will not be misplaced due to the friction between the two caused by the lateral movement when being transferred by the loading plate 10, thereby avoiding the structural jamming when it is subsequently inserted into the socket wrench 6. At the same time, when the loading plate 10 is moved upward to insert the nut into the socket wrench 6, it can contact the socket wrench 6 faster and be inserted more thoroughly, thereby further ensuring the installation efficiency of the nut feeding, and further improving the assembly efficiency of the assembly 2 from the perspective of ensuring the feeding quality. In this process, since the nut is in a state of being supported and moved upward by the loading plate 10, this process does not require a groove and the two will not be misplaced.

[0060] Embodiment 3, based on the above embodiment:

[0061] See also Figures 3 to 15 The switching component includes: 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 are meshed with the teeth of the gear 32, the ends of the two triangular toothed plates 31 are hinged with hinged rods 33, and the ends of the two hinged rods 33 are respectively hinged to the surfaces of the two displacement frames 19;

[0062] A ratchet plate 34 is fixedly connected to the shaft wall of the rotating shaft 1 22 , a spring 35 is fixedly connected to the inner wall of the body 3 , an end of the spring 35 is fixedly connected to a clamping plate 36 , and an end of the clamping plate 36 is rotatably connected to the inner wall of the body 3 .

[0063] More specifically, in this embodiment: when the displacement frame 19 moves vertically upward, the triangular tooth plate 31 is pulled to slide on the surface of the fixed plate 30 through the transmission of the hinge rod 33. At this time, the inclined surface of the triangular teeth of the triangular tooth plate 31 presses against the gear 32. Therefore, the displacement of the triangular tooth plate 31 will only cause the triangular teeth thereon to be continuously squeezed, and will not drive the gear 32 to rotate. The card plate 36 and the ratchet plate 34 under this process structure also further ensure this purpose by ensuring the single rotation direction of the rotating shaft 22. 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 is used to connect the gear 32 to the fixed plate 30. The displacement of the triangular tooth plate 31 will drive the gear 32 to rotate, and the rotation of the gear 32 will drive the shaft 1 22 to rotate. In 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 shaft 1 22, the polygonal groove and the polygonal block 24 cooperate to make the shaft 2 23 rotate synchronously. Through the rotation of the shaft 2 23, the nut plate 9 can be self-deflected. During the deflection of the nut plate 9, the nut in a nut sleeve thereon will fall from the loading port, pass through the telescopic cylinder 21 and fall into the groove on the loading plate 10, completing the automatic replenishment of the nut.

[0064] It is worth noting that when the loading plate 10 is loading, the telescopic cylinder 21 is compressed, and 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 movement 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 loading plate 10, that is, the nut will not fall anywhere else. In the second half of the downward movement path, the loading plate 10 is separated from the lower end of the telescopic cylinder 21, so that the setting of the telescopic cylinder 21 ensures the accuracy of loading.

[0065] By adopting the above method, after each pair of nut is installed on an assembly 2, the nut plate 9 will be deflected once, so that the next nut falls into the groove on the loading plate 10, thereby realizing automatic material replenishment, preparing for the assembly of the next assembly 2, and further improving the assembly efficiency.

[0066] Embodiment 4, based on the above embodiment:

[0067] See also Figures 2 to 15The mating parts include: a connecting sleeve 37, which is rotatably connected to the shaft wall of the rotating shaft 23, and two transmission shafts 38 are fixedly connected to the surface of the connecting sleeve 37. Both sides of the mating cylinder 13 are provided with through openings for the displacement of the two transmission shafts 38. Two baffles 39 are fixedly connected to the surface of the outer shell 1, and the opposite sides of the two baffles 39 are fixedly connected with mating grooves 40. The mating grooves 40 include straight grooves and oblique grooves. The shaft walls of the two transmission shafts 38 are slidably connected to the groove walls of the two mating grooves 40 respectively.

[0068] More specifically, in this embodiment: when all the assemblies 2 on the assembly line are assembled, the reset cylinder 42 can be driven to displace the matching cylinder 13 in the direction away from the insertion cylinder 8. At this time, the two transmission shafts 38 slide along the straight grooves on the two matching grooves 40 respectively. When the matching cylinder 13 moves to the end, the transmission shaft 38 is displaced to slide along the oblique groove on the matching groove 40, that is, the two transmission shafts 38 move vertically upward, thereby causing the connecting sleeve 37 to move vertically upward, and then causing the second rotating shaft 23 to move vertically upward. The vertical upward movement can make the polygonal block 24 disengage from the polygonal groove, that is, the second shaft 23 loses the limit position consistent with the first shaft 22. In this state, the nut plate 9 can be rotated in any direction, that is, after the device is used, the personnel can easily carry out additional inspections on the nuts on the nut plate 9 as needed, without the need to rotate in a fixed direction and overcome certain structural resistance. This makes it convenient for personnel to carry out periodic material replenishment, or because there is no nut plate 9 and other components in the socket wrench 6 area, it is convenient to repair the socket wrench 6 area, thereby comprehensively improving the practical efficiency of the device.

[0069] See also Figures 1 to 16 The present invention provides an automobile shock absorber assembly assembly method as follows:

[0070] The assembly 2 to be assembled is placed in the insertion tube 8 on the housing 1, and a large number of nuts are added to the nut plate 9 in advance, and a nut is initially placed in the groove on the upper material plate 10, and then the reset cylinder 42 is started to make the insertion tube 8 slide along the inner wall of the housing 1, at this time, the component above it is driven to approach the socket wrench 6, and the drive of the reset cylinder 42 is stopped after the approach is completed, and this position is maintained, and then an assembly is started. During assembly, two buttons can be set on the housing 1, one for controlling the motor 41, and the other for controlling the cylinder group 4. and the motor 5. At this time, the motor 41 is started first to drive the main shaft 14 to rotate one circle, thereby driving the loading plate 10 to perform a displacement with a U-shaped characteristic, so that the nut is efficiently clamped into the socket wrench 6. Then, the cylinder group 4 is started to drive the motor 5, the extrusion assembly 7 and the socket wrench 6 to move downward. Through the downward movement of the extrusion assembly 7, the spring in the assembly 2 is extruded and installed. 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;

[0071] When the loading plate 10 first approaches the direction of the socket wrench 6, the push plate 12 follows the displacement plate 11 to move closer to the socket wrench 6 and gradually moves upward. By moving the push plate 12 upward, the nut can be gradually pushed out from the groove. When the nut is displaced to just below the socket wrench 6, the nut is completely pushed out. When the loading plate 10 moves downward vertically to reset, the nut plate 9 will produce a self-deflection, so that a nut in a nut sleeve will fall from the loading port, pass through the telescopic cylinder 21 and fall into the groove on the loading plate 10, completing the automatic replenishment process of the nut.

[0072] When all the assemblies 2 on the production line are assembled, the reset cylinder 42 can be driven to displace the matching cylinder 13 in the direction away from the insertion cylinder 8, so that after the device is used up, the second shaft 23 loses the limit consistent with the first shaft 22, so that the nut plate 9 can be rotated in any direction. Therefore, after the device is used up, the personnel can easily perform additional inspections on the nuts on the nut plate 9 as needed, without the need to rotate in a fixed direction and overcome certain structural resistance. This makes it convenient for personnel to perform periodic material replenishment, or because there is no nut plate 9 lamp component in the socket wrench 6 area, it is convenient to inspect the socket wrench 6 area, thereby comprehensively improving the practical efficiency of the device.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
