Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Examples: referring to fig. 1-4, an embodiment of the invention provides an automatic assembling line for an automobile seat framework, which comprises a skid conveyer belt 1, wherein the top of the skid conveyer belt 1 is slidably connected with a movable plate 2, the inside of the movable plate 2 is rotatably connected with a first rotating shaft 11, the top of the first rotating shaft 11 is fixedly connected with a bottom plate 3, the bottom of the outer wall of the first rotating shaft 11 is fixedly connected with a special-shaped block 9, the inside of the special-shaped block 9 is provided with a first annular array sliding groove 12, one side of the bottom of the movable plate 2 is rotatably connected with a second rotating shaft 16, the top of the outer wall of the second rotating shaft 16 is fixedly connected with a second special-shaped block 10, one side of the bottom of the special-shaped block 10 is fixedly connected with a fixing rod 19, one side of the top of the fixing rod 19 is fixedly connected with a first upright post 18, the outer wall of the first upright post 18 is slidably connected inside the sliding groove 12, the bottom of the outer wall of the second rotating shaft 16 is fixedly connected with a gear 15, one side of the inside of the gear 15 is fixedly connected with a limiting post 17, the inside of the skid conveyer belt 1 is fixedly connected with a cross rod 7, a limiting groove 13 is formed inside the cross rod 7, the outer wall of the limiting post 17 is slidably connected inside the limiting post 13, a plurality of racks 14 are fixedly connected inside the cross rod 7, and the outer walls of racks 14 are meshed with the outer walls of the gear 15.

The skid conveyor belt 1 is the driving force of the system, and the parallel movement of the seat frame is realized by pulling the movable plate 2. A floor 3 is fastened under the moving plate 2, and the entire moving unit is advanced together while carrying the car seat frame. This synchronous movement mechanism allows for a smooth transition of the seat frame between the different workstations, performing various assembly and processing steps.

The hydraulic rod 4 is used for adjusting the height of the automobile seat framework, and the height adjusting function is particularly important in the assembly work of the bottom of the seat framework, wherein the height is suitable for different assembly requirements through lifting. This not only increases the flexibility of assembly, but also ensures ergonomic comfort for the worker during assembly.

During the movement of the moving plate 2, the gear 15 at the bottom rotates. The outer wall of the gear 15 is provided with a limit post 17 which slides in a limit groove 13 on the inner wall of the cross bar 7. This design prevents any rotation of the gears during movement, ensuring stability of the overall transmission system. When the gearwheel 15 reaches the position of the rack 14, the crossbar 7 releases the restriction on the gearwheel, which is free to roll on the rack. After the gear rolls on the rack, the limit post 17 slides into the limit groove 13 again, so that the mechanism is locked again, and the synchronization and safety of the system are maintained.

In addition, the rotation of the gear 15 drives the special-shaped block two 10 to rotate through the rotation shaft two 16. The fixed rod 19 at the bottom of the special-shaped block II 10 also rotates along with the special-shaped block II, so that the upright post I18 slides into the chute I12 in the special-shaped block I9. The pushing of the column I18 rotates the profiled block I9 by 90 degrees, which is transmitted to the bottom plate 3 on top of the moving plate 2 through the rotation shaft I11, and the bottom plate 3 is correspondingly rotated by 90 degrees. The steering mechanism provides adjustment in the direction for the automobile seat framework, meets assembly requirements in different directions, and improves flexibility and efficiency of a production line. The design of the whole system considers the precise control and mechanical efficiency, and ensures the continuity and reliability in the production process.

Referring to fig. 5-6, the lifting assembly includes a hydraulic rod 4 and a buffer seat 5, the bottom of the hydraulic rod 4 is fixedly connected to the top of the bottom plate 3, the bottom of the buffer seat 5 is fixedly connected to the output end of the hydraulic rod 4, the top of the buffer seat 5 is fixedly connected to a plurality of dampers I8, the output end of the dampers I8 is fixedly connected to a fixing plate I6, the bottom of the fixing plate I6 is fixedly connected to a plurality of fixing blocks 25, the top of the buffer seat 5 is fixedly connected to a fixing plate II 24, one side of the outer wall of the fixing block 25 is rotatably connected to a plurality of transmission rods I30, one side of the transmission rods I30 is rotatably connected to a sliding block II 37, the top of the buffer seat 5 is fixedly connected to a plurality of sliding rails 20, the bottom of the sliding block II 37 is slidably connected to the outer wall of the sliding rails 20, one side of the outer wall of the sliding block II 37 is fixedly connected to a sliding rod 26, the outer wall of the sliding rod 26 is slidably connected to the inside the fixing plate II 24, one side of the outer wall of the fixing block 25 is rotatably connected to a rotating block I28, one side of the outer wall of the rotating block II 28 is fixedly connected to a damper II 21, one side of the outer wall of the sliding block II 37 is rotatably connected to a second 29, the output end of the damper II 21 is fixedly connected to one side of the outer wall of the rotating block 29, one side of the outer wall of the sliding rod is fixedly connected to one side of the outer wall 27, one side of the other side of the outer wall 27 is fixedly connected to one side of the other side of the outer wall 27, and one side of the other side of the outer wall is fixedly connected to one side of the outer side 27.

In the assembly process of the automobile seat framework, a fine force management and damping mechanism is of great importance so as to ensure the assembly quality and prolong the service life of the finished product. The first fixing plate 6 for fixing the automobile seat frame is a key component in the mechanism and is connected with the buffer seat 5 through the first damper 8. This configuration allows the first fixing plate 6 to be effectively damped and cushioned when subjected to force, thereby protecting the seat frame from excessive impact and stress, enhancing durability and safety of the product.

When the first fixing plate 6 is subjected to a force, the force is transmitted to the second slider 37 via the first transmission rod 30. The transmission rod I30 is designed to uniformly transmit force, and the damper II 21 connected with the transmission rod I further performs vibration reduction treatment on the transmission process, so that the power transmitted by the fixing plate I6 is effectively absorbed and dispersed. This design not only protects the integrity of the mechanical structure, but also optimizes the operational smoothness of the assembly line.

After the force is transferred to the second slider 37, the second slider is urged to slide on the slide rail 20. The slide rail 20 provides a stable sliding path for the second slider 37, allowing it to move smoothly while receiving force. Such sliding not only helps to further distribute the forces, but also protects the structural safety of the seat frame by reducing localized stress concentrations.

During the sliding of the second slider 37, the spring 27 connected thereto is compressed. This compression provides additional cushioning capacity for the overall force dispersion process. The compression and release of the spring 27 not only provides the necessary reaction force to assist the return of the second slider 37 to the original position, but also plays an important role in damping and further relieves the impact force during the transfer process. The integrated buffering and damping mechanism ensures the accuracy and safety in the assembly process, reduces the abrasion and tearing in the production process, and prolongs the whole service life of the product.

Referring to fig. 7-8, a rack 22 is fixedly connected to the top of the first fixing plate 6, a clamping jaw 23 is rotatably connected to the inside of the rack 22, air cylinders 36 are fixedly connected to two sides of the top of the first fixing plate 6, push-pull plates 31 are slidably connected to two sides of the inside of the rack 22, one side of the outer wall of each push-pull plate 31 is fixedly connected to the output end of each air cylinder 36, a plurality of second sliding grooves 32 are formed in the inside of each push-pull plate 31, a plurality of first sliding blocks 34 are slidably connected to the inside of each fixing plate 6, a second upright post 33 is fixedly connected to one side of the top of each first sliding block 34, the outer wall of each second upright post 33 is slidably connected to the inside of each second sliding groove 32, a transmission rod second 35 is rotatably connected to one side of each transmission rod second 35, and one side of each transmission rod is rotatably connected to one side of the inside of the clamping jaw 23.

In an automated automotive seat frame assembly line, it is critical to use highly precise mechanical systems to ensure stability and assembly quality of the seat frame. The process begins with the placement of the car seat frame on the carrier 22. The shelf 22 provides an initial attachment point for the seat frame to ensure accurate placement during assembly.

The cylinder 36 functions to drive the push-pull plate 31 to move along a prescribed path. The design of the push-pull plate 31 enables a smooth rectilinear movement which directly affects the other mechanical components connected thereto. With the movement of the push-pull plate 31, the second chute 32 connected with the push-pull plate correspondingly moves. The second chute 32 is a critical component, and its inner wall is designed so that the second column 33 can slide along a predetermined trajectory inside it.

The movement of the second post 33 is critical to the overall assembly process, as it directly pushes the first slider 34. The first slider 34 slides along the set track to the outside, which is achieved by precise mechanical force transmission. With the movement of the first slider 34, the second transmission rod 35 is activated, which rod drives the jaw 23 into rotation via its mechanical connection.

The rotation of the clamping jaws 23 is the final action in this automatic assembly process, the function of which is to grip tightly the outer wall of the car seat frame, ensuring that the seat frame is stationary in the subsequent assembly steps. The design of the clamping jaw 23 allows it to exert a uniform pressure on the seat frame, thereby avoiding damage to the seat frame, while ensuring accurate positioning thereof during assembly. The automatic clamping mechanism not only improves the assembly efficiency, but also improves the consistency and quality of products, so that the whole production line can operate more smoothly and efficiently.

Although embodiments of the present 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 therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
