Technical Field

[0001] This utility model relates to the field of automotive interior manufacturing technology, specifically a tooling fixture for the production of automotive interior headliners. Background Technology

[0002] With the increasing number of cars, the car interior has become an important part of the car body. The car roof has the characteristics of decoration, sound absorption, and heat insulation. The car roof has become an important factor for people to choose a car. Therefore, the requirements for car interior parts are getting higher and higher. During the production process, the car roof needs to be clamped and fixed.

[0003] A positioning fixture for automobile roof production, disclosed in publication CN 212794060 U, includes a main body comprising a frame, a placement plate, and a roof body. The placement plate is fixedly connected to the middle of the frame, and the roof body is fixedly connected above the placement plate. A clamping mechanism, including clamping blocks, is provided on the outer surface of the roof body. Clamping blocks are held on both the upper and lower ends of the roof body, and a first connecting rod is fixedly connected to the end of each clamping block away from the roof body. The ends of four sets of first connecting rods away from the roof body are connected to the outer walls of the front and rear sides of the frame via pivots, and a pressing plate is fixedly connected to the other end of each first connecting rod. A first sliding groove is formed on the inner wall of each of the four pressing plates. This invention allows for the rapid fixing of the roof body, is simple and convenient to operate, saves workers' time, and improves the practicality and convenience of the device.

[0004] However, the above-mentioned positioning fixture still has some shortcomings in use. Once the car roof is fixed, the overall height and position are also fixed, and the height cannot be adjusted according to the actual production and processing needs. Furthermore, when it is necessary to process both sides of the car roof, it is necessary to manually disassemble the car roof, adjust its position, and then re-fix it, which is time-consuming, labor-intensive, and inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tooling fixture for the production of automotive interior headliners. It solves the problems that once the automotive headliner is fixed, its overall height and position are also fixed, making it impossible to adjust the height according to actual production and processing needs. Furthermore, when processing both sides of the automotive headliner is required, it is necessary to manually disassemble the headliner, adjust its position, and then re-fix it, which is time-consuming, labor-intensive, and inconvenient to use.

[0006] This utility model provides the following technical solution: a tooling fixture for the production of automotive interior headliners, including a worktable, two support frames fixedly connected to the upper surface of the worktable, a screw rod rotatably connected between the inner top wall and bottom wall of the two support frames, a threaded sleeve on the surface of the two screw rods, a first motor fixedly connected to the opposite side of the two threaded sleeves, and a connecting plate fixedly connected to the output end of the two first motors, the two connecting plates being L-shaped;

[0007] Each of the two connecting plates has a set of fixing plates fixedly connected to its opposite sides. Each fixing plate has a threaded groove on its surface, and a lead screw is threaded into the inside of each threaded groove. A pressure plate is rotatably installed at the bottom end of each lead screw.

[0008] Preferred technical solution 1: Each of the support frames has a sliding groove on both inner side walls, and a slider is slidably connected inside each sliding groove. Each slider is fixedly connected to the corresponding screw sleeve.

[0009] Preferred technical solution 2: A set of limiting holes is provided on the upper surface of each of the fixed plates, and a limiting rod is slidably sleeved inside each of the limiting holes. The bottom end of each limiting rod is fixedly connected to the corresponding pressure plate.

[0010] Preferred technical solution 3: A bracket is fixedly connected to the lower surface of the workbench, a second motor is fixedly connected to the upper surface of the bracket, a double-row sprocket is fixedly connected to the output end of the second motor, the bottom ends of the two screws extend to the bottom of the workbench and are fixedly sleeved with driven sprockets, and a chain is connected between the two driven sprockets and the double-row sprockets.

[0011] Preferred technical solution four: A rubber pad is fixedly adhered to the surface of each connecting plate and the surface of each pressure plate, and each rubber pad is provided with anti-slip texture.

[0012] Preferred technical solution five: Support legs are fixedly connected to the four corners of the lower surface of the workbench, and an anti-slip pad is fixedly connected to the bottom of each support leg.

[0013] Compared with the prior art, this utility model provides a tooling fixture for the production of automotive interior headliners, which has the following advantages: In use, the automotive headliner is placed on two connecting plates, and then multiple screws are rotated to drive multiple pressure plates downward. The pressure plates cooperate with the connecting plates to press and fix the automotive headliner, allowing for processing. At the same time, the rotation of a second motor drives a double-row sprocket to rotate, which in turn drives two driven sprockets and two screws to rotate through chain transmission, thereby driving the screw sleeve to rise and moving the automotive headliner upward, allowing for height adjustment. This facilitates processing for different situations. In addition, the rotation of two first motors can drive the two connecting plates and the automotive headliner to rotate, allowing their upper and lower surfaces to be interchanged. This facilitates processing different surfaces of the automotive headliner without the need to disassemble, adjust, and re-fix the headliner, saving time and effort, and making the process convenient and quick.

[0018] Please see Figure 1-3 ,

[0019] Example 1: A tooling fixture for the production of automotive interior headliners includes a workbench 1. Two support frames 2 are fixedly connected to the upper surface of the workbench 1. Screws 3 are rotatably connected between the inner top and bottom walls of the two support frames 2. Screw sleeves 4 are threaded onto the surfaces of the two screws 3. First motors 5 are fixedly connected to the opposite sides of the two screw sleeves 4. Connecting plates 6 are fixedly connected to the output ends of the two first motors 5. Both connecting plates 6 are L-shaped.

[0020] A set of fixing plates 7 are fixedly connected to the opposite sides of the two connecting plates 6. Each fixing plate 7 has a threaded groove 8 on its surface. Each threaded groove 8 has a threaded screw 9 threaded inside. Each screw 9 has a pressure plate 10 rotatably installed at its bottom end.

[0021] Example 2: The difference between this example and Example 1 is that each support frame 2 has a sliding groove 11 on both inner side walls, and a slider 12 is slidably connected inside each sliding groove 11. Each slider 12 is fixedly connected to the corresponding screw sleeve 4, and the lifting and lowering of the screw sleeve 4 is restricted by the slider 12 and the sliding groove 11.

[0022] Example 3: The difference between this example and Example 1 is that each fixed plate 7 has a set of limiting holes 13 on its upper surface, and each limiting hole 13 has a limiting rod 14 slidably fitted inside it. The bottom end of each limiting rod 14 is fixedly connected to the corresponding pressure plate 10, so as to press the car roof tightly through the pressure plate 10.

[0023] Example 4: The difference between this example and Example 1 is that a bracket 15 is fixedly connected to the lower surface of the workbench 1, a second motor 16 is fixedly connected to the upper surface of the bracket 15, a double-row sprocket 17 is fixedly connected to the output end of the second motor 16, the bottom ends of the two screws 3 extend to the bottom of the workbench 1 and are fixedly sleeved with driven sprockets 18, and the two driven sprockets 18 are connected to the double-row sprockets 17 by a chain 19. The rotation of the second motor 16 can drive the two screws 3 to rotate, thereby raising and lowering the car roof.

[0024] Example 5: The difference between this example and Example 1 is that rubber pads are fixedly adhered to the surface of each connecting plate 6 and the surface of each pressure plate 10. Each rubber pad has anti-slip textures on its surface to protect the car roof and prevent damage caused by excessive force.

[0025] Example 6: The difference between this example and Example 1 is that the four corners of the lower surface of the workbench 1 are fixedly connected with support legs 20, and the bottom of each support leg 20 is fixedly connected with an anti-slip pad, making the whole structure more stable.

[0026] In summary, this tooling fixture for producing automotive interior headliners features two screws 3 with opposite screw directions. During use, the headliner is placed on two connecting plates 6, and then multiple screws 9 are rotated to move multiple pressure plates 10 downwards. The pressure plates 10, in conjunction with the connecting plates 6, press and fix the headliner, allowing for processing. Simultaneously, the rotation of the second motor 16 drives the double-row sprocket 17, which in turn drives the two driven sprockets 18 and the two screws 3 via the chain 19, causing the screw sleeve 4 to rise and thus moving the headliner upwards. This allows for height adjustment, facilitating processing for different situations. Furthermore, the rotation of the two first motors 5 rotates the two connecting plates 6 and the headliner, allowing for the interchange of their upper and lower surfaces. This facilitates processing different surfaces of the headliner without disassembling, adjusting, and re-fixing it, saving time and effort, and providing convenience and speed.
