Technical Field

[0001] This utility model relates to the field of leather patching technology for driver's side airbag door cover, and more specifically, to a structure for applying leather patch to the driver's side airbag door cover of a car. Background Technology

[0002] In existing technologies, during the production of the driver's side airbag cover assembly, the leather patch application process is fixed to a fixture, which cannot be adjusted in angle or height. This means that when manually applying the leather patch, some areas requiring adhesion to corners cannot be worked at the same angle, necessitating adjustments to the fixture's angle for a better application. This situation causes workers to expend considerable time and energy, reducing work efficiency and easily leading to fatigue.

[0003] Therefore, this application proposes a structure for attaching a leather patch to the driver's side airbag door cover of a car, in order to solve the aforementioned problems. Utility Model Content

[0004] To address the aforementioned issues, this application provides a structure for attaching a leather patch to the driver's side airbag door cover of a car.

[0033] Example:

[0034] The following is in conjunction with the appendix Figure 1 -5 provides further details regarding this application.

[0035] This application discloses a structure for attaching a leather patch to the driver's side airbag door cover of a car, including:

[0036] Base plate 1, structural frame 2 is vertically installed on base plate 1, and foot valves 3 are symmetrically installed on base plate 1;

[0037] A pneumatic tooling is fixedly installed on the structural frame 2. The pneumatic tooling includes a cylinder 4, a housing 5, a floating clamping block 6, a fixed clamping block 7, and a rocker arm 8. The cylinder 4 is located at the bottom of the housing and the piston extends into the interior of the housing. A movable block 10 is slidably installed inside the housing, and the end of the movable block 10 is detachably connected to the piston of the cylinder 4.

[0038] The first end of the movable block 10 penetrates the outer shell and extends outward through the floating clamping block 6, and is then fixedly connected to the fixed clamping block 7. The floating clamping block 6 is located between the fixed clamping block 7 and the outer shell. The rocker arm 8 is initially clamped between the fixed clamping block 7 and the floating clamping block 6.

[0039] The other end of the rocker arm 8 is connected to the outer casing 2 11. The bottom of the outer casing 2 11 is connected to the cylinder 2 9, and the piston part extends into the outer casing 2 11. Inside the outer casing 2 11, tapered roller bearings 12 are symmetrically arranged above and below with the piston of the cylinder 2 9 as the center. A rotating shaft 13 is rotatably arranged inside the outer casing 2 11. The rotating shaft 13 engages with the tapered roller bearings 12, and its bottom is connected to the piston of the cylinder 2 9, while its top passes through the outer casing 2 11. The rotating shaft 13 is used to install the corresponding model of workpiece clamping equipment.

[0040] Cylinder 4 and cylinder 9 are pneumatically connected to the foot pedal valve 3, which is symmetrically arranged.

[0041] See Figure 3 The outer casing 5 is also equipped with an oil-free bushing 14, which encloses the movable block 10. A fastening nut 15 is rotatably installed at the bottom of the movable block 10, and the threaded end of the fastening nut 15 is connected to the piston thread of the cylinder 9. A rotation limit block 16 is also provided at the front end of the outer casing 5, which engages with the movable block 10 to limit the rotation of the movable block 10. The oil-free bushing 14, the fastening nut 15 and the rotation limit block 16 can improve the stability and reliability of the movable block 10, making it more stable during operation.

[0042] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A buffer washer 17 is also provided between the floating clamp 6 and the outer shell 5; the use of the buffer washer 17 can reduce the impact force between the floating clamp 6 and the fixed clamp 7, thereby protecting the tooling and the leather sheet and preventing them from being damaged during operation.

[0043] See Figure 4 The rocker arm 8 has a hollow internal structure. A pneumatic connector is connected to the rocker arm 8 in the direction of the cylinder 4. The part of the rocker arm 8 located between the fixed clamping block 7 and the floating clamping block 6 is the rocker arm shaft 18. The rocker arm shaft 18 is also a hollow structure with a rotary pneumatic connector at its head. The end of the rocker arm shaft 18 is connected to the pneumatic connector on the rocker arm, and a coupling 19 is provided outside the connection. The configuration of the hollow rocker arm 8, the pneumatic connector, and the rotary pneumatic connector enables pneumatic clamping and flexible rotation of the leather piece, making the installation process more convenient.

[0044] See Figure 1 It also includes a mechanism frame, on which a placement plate 20 is set directly below the pneumatic tooling, and a hot air gun holder 21 is set on the placement plate 20; above the pneumatic tooling, the mechanism frame is also equipped with an operation signboard 22 and a fluorescent light 23; the configuration of the placement plate 20, the hot air gun holder 21, the operation signboard 22 and the fluorescent light 23 improves the practicality and ease of operation of the tooling, making the work more efficient.

[0045] See Figure 4 and Figure 5 A clamping pin 24 is provided between the rotating shaft 13 and the piston of the cylinder 2 9, with the conical surface of the clamping pin 24 facing the rotating shaft 13. The use of the clamping pin 24 can ensure the stable rotation and precise positioning of the rotating shaft 13, thereby ensuring the installation quality of the leather piece.

[0046] The implementation principle of the structure for attaching a leather patch to the driver's side airbag door cover in this application embodiment is as follows:

[0047] The working principle of cylinder 4: When the foot pedal valve 3, which controls cylinder 4, is pressed, the fixed clamp 7, rocker arm shaft 18, and adjusting bolt move forward together when cylinder 4 extends, while the floating clamp 6 remains stationary. At this time, the rocker arm shaft 18 connected to the rocker arm has sufficient space to rotate. Conversely, when the cylinder retracts, the fixed clamp 7, rocker arm shaft 18, and adjusting bolt move backward. The fixed clamp 7 drives the floating clamp 6 to apply pressure to the buffer washer 17. At this time, the rocker arm shaft 18 connected to the rocker arm is tightly clamped by the floating clamp 6 and cannot rotate.

[0048] Working principle of cylinder 2, part 9: When the foot pedal valve 3, which controls cylinder 2, is pressed down, the clamping pin 24 moves upward when the cylinder extends, forcing the clamping shaft 13 and the roller bearing to move upward together, thus making full contact with the pressure block and preventing the shaft 13 from rotating. When the cylinder retracts, the clamping pin 24 moves towards the cylinder, causing the force on the clamping shaft 13 to disappear, at which point the product can rotate.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
