Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for seat assembly, specifically an auxiliary tooling for assembling rear seats of automobiles. Background Technology

[0002] Car seats provide comfortable posture support for drivers and passengers. During car travel, the human body needs to maintain a stable posture. The seat cushion and backrest are designed to conform to ergonomic principles, support the body weight, and reduce muscle fatigue. For example, the seat cushion can support the buttocks and thighs, allowing for smooth blood circulation in the legs; the backrest can conform to the curve of the back, providing appropriate support for the waist and back, and preventing lower back pain caused by prolonged sitting.

[0003] Auxiliary tooling is needed during the installation of rear seats into seat bases in automobiles. Chinese utility model patent CN219005953U discloses an auxiliary tooling for automobile seat assembly, including a workbench. A first hydraulic telescopic rod is fixedly installed on one side of the bottom of the workbench. In this solution, the worker first adjusts the height of the workbench by activating the first hydraulic telescopic rod via a control terminal, according to their own height, thus facilitating height adjustment and making it suitable for workers of different heights. In this solution, the worker activates a second hydraulic telescopic rod via a control terminal, which pushes a second clamping plate to move and clamp the automobile seat frame. When it is necessary to rotate the automobile seat, the worker activates a drive motor, which drives a rotating shaft to rotate. The rotating shaft drives the base plate to rotate, thereby rotating the automobile seat frame. This facilitates the rotation of the base plate, allowing the automobile seat frame to rotate without the worker having to move, thus improving assembly efficiency.

[0004] The utility model proposes a second hydraulic telescopic rod to move the second clamping plate and clamp the car seat frame. However, existing auxiliary tooling clamps the side of the car seat frame by squeezing, which cannot achieve centered clamping and does not clamp the front, back, or left and right sides of the car seat frame, making assembly inconvenient. At the same time, its fixing stability is poor, which reduces the assembly quality. Therefore, an auxiliary tooling for assembling the rear seat of a car is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an auxiliary tooling for assembling rear seats of automobiles. It has the advantages of simultaneously clamping the front, back, and left and right sides of the car seat frame and centering the frame. This solves the problems of existing auxiliary tooling, which cannot achieve centering clamping and does not clamp the front, back, and left and right sides of the car seat frame, making assembly inconvenient. In addition, its fixing stability is poor, which reduces the assembly quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary tooling for assembling a car rear seat includes a tooling frame and an auxiliary platform. The auxiliary platform has a fixing mechanism on its inner side for clamping the front, back, left and right sides and centering the car seat frame.

[0008] The fixing mechanism includes cylinders fixedly connected to the left and right sides of the auxiliary platform. The output shaft of the cylinder is fixedly connected to a push plate. A clamping frame is fixedly connected to the outer side of the push plate. Electric push rods are fixedly connected to the front and back of the clamping frame. A push block is fixedly connected to the output shaft of the electric push rod. Two hinge frames are fixedly connected to the inner side of the clamping frame. A clamping arm is hinged to the inner side of the hinge frame. The front end of the push block is hinged to the outer side of the clamping arm. A buffer assembly for shock absorption during assembly is provided on the inner side of the tooling frame.

[0009] Furthermore, the buffer assembly includes a sliding rod fixedly connected to the inside of the tooling frame, a lower pressure plate slidably connected to the outer surface of the sliding rod, a damper and an airbag fixedly connected to the inner bottom wall of the tooling frame, and the bottom of the auxiliary platform fixedly connected to the top of the lower pressure plate.

[0010] Furthermore, the top of the damper is fixedly connected to the bottom of the lower pressure plate, and the number of sliding rods is four.

[0011] Furthermore, air tubes for inflation are fixedly connected to the left and right sides of the airbag, and one-way valves are installed on the outside of the air tubes.

[0012] Furthermore, a limit rod and a worktable are fixedly connected to the inner side of the auxiliary platform, and the push plate is slidably connected to the limit rod.

[0013] Furthermore, the workbench is circular in shape, and a magnetic chuck for positioning the seat base is fixedly connected to the top of the workbench.

[0014] Furthermore, both the tooling frame and the auxiliary platform are steel structures, and the auxiliary platform is square in shape.

[0015] Furthermore, the bottom of the tooling frame is fixedly connected with a protective edging, which is made of aluminum alloy.

[0016] Compared with the prior art, this utility model provides an auxiliary tooling for assembling rear seats in automobiles, which has the following beneficial effects:

[0017] 1. The auxiliary tooling for assembling the rear seats of this car has a fixing mechanism consisting of two cylinders. The cylinders can simultaneously push two clamping frames close to the car seat frame via a push plate to clamp and fix the left and right sides of the car seat frame, achieving centered clamping and facilitating assembly by the workers. At the same time, the electric push rod can push the clamping arm via a push block, causing the clamping arm to rotate inside the hinge frame, thereby clamping and fixing the front and rear ends of the car seat frame, thus strengthening the fixing stability and ensuring assembly quality.

[0018] 2. The auxiliary tooling for assembling the rear seats of this car has a buffer component, which realizes the function of buffering and shock absorption for the auxiliary platform. When the auxiliary platform is impacted during the assembly of the car seat frame, the lower pressure plate will slide on the outer surface of the sliding rod, thereby squeezing the damper and airbag. At this time, the damper and airbag can use their own elastic buffering effect to reduce the vibration and impact during the assembly process, making the installation of parts more accurate and improving the assembly quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3An auxiliary tooling for assembling a car rear seat in this embodiment includes a tooling frame 1 and an auxiliary platform 2. The auxiliary platform 2 is provided with a fixing mechanism for clamping the front, back, left and right sides and centering the car seat frame. The fixing mechanism includes cylinders 3 fixedly connected to the left and right sides of the auxiliary platform 2. The output shaft of the cylinders 3 is fixedly connected to a push plate 4. A clamping frame 5 is fixedly connected to the outer side of the push plate 4. Electric push rods 6 are fixedly connected to the front and back of the clamping frame 5. A push block 7 is fixedly connected to the output shaft of the electric push rod 6. Two hinge frames 8 are fixedly connected to the inner side of the clamping frame 5. A clamping arm 9 is hinged to the inner side of the hinge frame 8. The front end of the push block 7 is hinged to the outer side of the clamping arm 9. The tooling frame 1 is equipped with a buffer assembly for shock absorption during assembly. The two cylinders 3 can simultaneously push the two clamping frames 5 close to the car seat frame through the push plate 4 to clamp and fix the left and right sides of the car seat frame, achieving centered clamping, which is convenient for workers to assemble. At the same time, the electric push rod 6 can push the clamping arm 9 through the push block 7, so that the clamping arm 9 rotates inside the hinge frame 8, thereby clamping and fixing the front and rear ends of the car seat frame, thereby strengthening the fixing stability and ensuring the assembly quality.

[0025] It should be noted that this application can ensure that the piston rods of the two cylinders 3 extend and retract simultaneously by using a synchronization controller or synchronization valve, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of pneumatic control, so they will not be described in detail in the specific embodiments.

[0026] In this embodiment, the buffer assembly includes a sliding rod 13 fixedly connected to the inner side of the tooling frame 1. A lower pressure plate 14 is slidably connected to the outer surface of the sliding rod 13. A damper 15 and an airbag 16 are fixedly connected to the inner bottom wall of the tooling frame 1. The bottom of the auxiliary platform 2 is fixedly connected to the top of the lower pressure plate 14. When the auxiliary platform 2 is impacted during the assembly of the car seat frame, the lower pressure plate 14 will slide on the outer surface of the sliding rod 13, thereby squeezing the damper 15 and the airbag 16. At this time, the damper 15 and the airbag 16 can use their own elastic buffering effect to reduce vibration and impact during the assembly process, making the installation of parts more accurate and improving the assembly quality.

[0027] It should be noted that the top of the damper 15 is fixedly connected to the bottom of the lower pressure plate 14, and there are four sliding rods 13. The sliding rods 13 serve to limit the lower pressure plate 14 and prevent it from moving randomly.

[0028] It should be noted that air tubes 17 for inflation are fixedly connected to the left and right sides of the airbag 16. One-way valves are installed on the outside of the air tubes 17. The air tubes 17 allow staff to inflate the airbag 16 regularly, and the one-way valves can seal the air passage to prevent air leakage.

[0029] Specifically, the inner side of the auxiliary platform 2 is fixedly connected to the limit rod 10 and the worktable 11, and the push plate 4 is slidably connected to the limit rod 10. The limit rod 10 can enhance the stability of the push plate 4 when it moves.

[0030] In this embodiment, the workbench 11 is circular in shape, and a magnetic chuck 12 for positioning the seat base is fixedly connected to the top of the workbench 11. The workbench 11 and the magnetic chuck 12 achieve the effect of positioning the assembly position of the car seat frame.

[0031] Specifically, both the tooling frame 1 and the auxiliary platform 2 are steel structures. The auxiliary platform 2 is square in shape. The steel structure of the tooling frame 1 and the auxiliary platform 2 makes them more durable and has a longer service life.

[0032] It should be noted that the bottom of the tooling frame 1 is fixedly connected with a protective edging 18. The edging 18 is made of aluminum alloy and serves to protect the bottom and edges of the tooling frame 1.

[0033] The working principle of the above embodiments is as follows:

[0034] During use, the operator first places the car seat frame on top of the workbench 11, where it is magnetically positioned by the magnetic suction cup 12 to prevent it from tipping over. Then, the two cylinders 3 are activated, which simultaneously push the two clamping frames 5 close to the car seat frame via the push plate 4 to clamp and fix the left and right sides of the car seat frame, achieving centered clamping for easy assembly. Subsequently, the electric push rod 6 is activated, which pushes the clamping arm 9 via the push block 7, causing the clamping arm 9 to rotate inside the hinge frame 8, thereby clamping and fixing the front and rear ends of the car seat frame, thus enhancing the stability of the fixation. In addition, when the auxiliary table 2 is impacted during the assembly of the car seat frame, the lower pressure plate 14 will slide on the outer surface of the sliding rod 13, thereby squeezing the damper 15 and the airbag 16. At this time, the damper 15 and the airbag 16 can use their own elastic buffering effect to reduce vibration and impact during the assembly process, making the installation of parts more precise.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
