Description

Technical Field

[0001] This utility model relates to the field of automotive interior technology, specifically to a plastic part leather bonding fixture. Background Technology

[0002] The interior system is an important part of the car body, and the design workload of the interior system accounts for more than 60% of the total design workload of the car body, far exceeding that of the exterior. It is one of the most important parts of the car body. With the rapid development of the modern automotive industry and the continuous improvement of people's living standards, people's requirements for car interiors have changed from practicality and durability to aesthetics, comfort and luxury.

[0003] Utility model patent CN215396985U discloses a fixture for covering automotive interior panels, including a base plate. A first groove is formed on the surface of the base plate, and a first slider is slidably connected to the inner wall of the first groove. A movable plate is mounted on the top of the first slider, and an insertion hole is formed inside the movable plate. An insertion post is movably inserted into the inner wall of the insertion hole, and a placement plate is provided on the top of the insertion post. In this utility model, by setting a second groove and a second slider inside the crossbar, under the elastic action of a telescopic spring, the user can move a fixed block within the crossbar by using the movable block.

[0004] This utility model, by setting a scraper and pad at the bottom of the fixed block, allows the scraper to scrape the outer wall of the covered part, ensuring the fit between the leather and the covered part. Furthermore, the fixed opening of the second sliding groove ensures that the scraper's movement path is uniform, thus ensuring the covering effect of the automotive interior panel. It is convenient for mass covering processing, and has a simple structure and is easy to operate.

[0005] However, the device has no fixed equipment on the placement board. After the covering part is placed on the placement board, it needs to be continuously supported by people in order to carry out the covering process. The long-term manual support is a great test of the physical endurance of the workers. At the same time, the manual support also has stability issues, which may affect the quality of leather bonding.

[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 Figure 1-3This application proposes a plastic part leather bonding fixture, including a base 1, which is rectangular in shape and its size is determined according to actual production needs. A positioning plate 2 is horizontally mounted on the upper side of the base 1. The positioning plate 2 is provided with a positioning block 21, the shape and size of which match the cavity structure at the bottom of the plastic part for precise fixing of the plastic part.

[0025] Furthermore, a support rod 5 is vertically installed on the base 1 at the position corresponding to the positioning plate 2, and a mounting block 51 is horizontally installed on the top of the support rod 5. The bottom of the positioning plate 2 is provided with a mounting plate 22, which is fixed to the mounting block 51 by bolts, so that the positioning plate 2 can be detached and installed. Different positioning plates 2 and positioning blocks 21 can be replaced for plastic parts with different structures.

[0026] Meanwhile, multiple through holes 23 are made on the positioning block 21, extending downwards and passing through the positioning plate 2. An air pipe connector 24 is installed on the lower side of the positioning plate 2 at the position corresponding to the through holes 23. The air pipe connector 24 is connected to an external vacuum device (such as a vacuum pump) via a pipe. When the vacuum device is activated, a vacuum can be created in the space inside the positioning block 21 through the through holes 23, thereby firmly adsorbing and fixing the plastic parts placed on the positioning block 21, increasing the stability of the plastic parts.

[0027] A connecting rod 3 is horizontally mounted on the upper side of the positioning plate 2, and one end of the connecting rod 3 is fixed to the upper side of the base 1 by a support column 31. A bonding assembly 4 is horizontally mounted on the connecting rod 3. The bonding assembly 4 includes a vertically arranged slide rod 41, and a mounting bracket 42 is horizontally mounted on the bottom of the slide rod 41. A bonding roller 43 is horizontally rotatably inserted into the lower side of the mounting bracket 42. The shape and size of the bonding roller 43 are designed according to the curvature of the plastic part surface to ensure good adhesion to the plastic part surface.

[0028] A sliding block 44 is provided at the position of the sliding rod 41 corresponding to the connecting rod 3, and the sliding rod 41 can slide longitudinally within the sliding block 44. A limiting block 45 is installed at the position of the sliding rod 41 above the sliding block 44. The limiting block 45 can abut against the upper side of the sliding block 44 to prevent the sliding rod 41 from disengaging from the sliding block 44.

[0029] A spring 46 is installed between the mounting bracket 42 and the sliding block 44. The spring 46 is sleeved on the slide rod 41. When the slide rod 41 moves downward, the spring 46 is compressed, generating an elastic force. When the slide rod 41 is released, the elastic force of the spring 46 pushes the bonding roller 43 against the top of the plastic part, ensuring that the bonding roller 43 is in close contact with the surface of the plastic part, thereby pressing the leather firmly onto the plastic part.

[0030] A limiting groove 32 is laterally formed at the middle of the connecting rod 3, corresponding to the position of the sliding block 44. The portion of the sliding block 44 located inside the limiting groove 32 is provided with a limiting slider 47, which can be limited within the limiting groove 32, thereby restricting the lateral movement trajectory of the sliding block 44 and ensuring that the fitting component 4 slides smoothly on the connecting rod 3.

[0031] Fixing blocks 48 are installed at the lower left and right ends of the mounting bracket 42, corresponding to the positions of the contact rollers 43. One of the fixing blocks 48 is slidably connected to the mounting bracket 42. A tension spring 49 is installed inside the mounting bracket 42 between the two fixing blocks 48. One end of the tension spring 49 is fixed to the mounting bracket 42, and the other end is fixedly connected to the slidable fixing block 48. The function of the tension spring 49 is to provide a certain elastic support for the contact rollers 43, enabling them to better adapt to the curvature changes of the plastic part surface.

[0032] A push rod 6 is fixedly installed on the left side of the upper part of the sliding block 44, which is located on the connecting rod 3. The push rod 6 is used to manually push the bonding assembly 4 to move laterally along the connecting rod 3, thereby driving the bonding roller 43 to roll on the surface of the plastic part, pressing the leather onto the plastic part, expelling air, and ensuring the adhesion between the leather and the plastic part.

[0033] In summary, the plastic-leather bonding fixture of this invention can effectively improve the bonding quality of leather and plastic parts, is easy to operate, has precise positioning, and is widely applicable, thus possessing significant practical value and promotional significance.
