Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing equipment technology, and more specifically, to a door edge pressing device. Background Technology

[0002] In the automobile manufacturing process, the edge sealing and pressing of the door is a crucial step, and its quality directly affects the overall sealing performance, appearance, and structural strength of the door.

[0003] Based on the above, the inventors have discovered that traditional door edge-sealing pressing methods often employ manual operation or simple mechanical devices. These methods are not only inefficient but also struggle to guarantee the stability and consistency of the pressing quality. Especially when processing doors of different models and specifications, traditional methods often require frequent adjustments to tools and parameters, increasing production difficulty and costs. Therefore, in view of this, the inventors have researched and improved upon existing structures to provide a door edge-sealing pressing device, aiming to achieve a more practical and valuable solution.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please see Figures 1-4 A door edge pressing device includes a base 1, a pressing platform 2 fixedly installed on the top of the base 1, a pressing frame 3 arranged directly above the pressing platform 2, a plurality of pressing blocks 4 fixedly installed at the bottom edge of the pressing frame 3, an extension arm 5 fixedly connected to the top four corners of the pressing frame 3, a support leg 6 fixedly connected to the top four corners of the base 1, a swing cylinder 7 fixedly installed on one side of the support leg 6, a swing arm 8 fixedly connected to the output end of the swing cylinder 7, a pressing block 9 fixedly connected to one end of the swing arm 8, a plurality of pad blocks 10 arranged between the bottom of the pressing block 9 and the top of one end of the corresponding extension arm 5, and a plurality of pad blocks 21 arranged between the top of the support leg 6 and the bottom of one end of the corresponding extension arm 5.

[0018] See Figure 3 The inner wall of the pressing frame 3 is welded and fixed with a cross-shaped inner support 12. During use, the welding and fixing of the cross-shaped inner support 12 further enhances the structural strength of the pressing frame 3 and ensures the stability and reliability of the pressing process.

[0019] See Figure 3 The pressing block 4 includes an upper pressing block 401 fixed to the bottom of the pressing frame 3, and a lower pressing block 402 is bolted to the bottom of the upper pressing block 401.

[0020] See Figure 3 The bottom end of the lower abutment block 402 is chamfered and located above the edge of the pressing table 2. In use, the chamfer at the bottom end of the lower abutment block 402 and its location above the edge of the pressing table 2 help to more accurately control the edge-wrapping effect of the car door and improve the overall quality of the product.

[0021] See Figure 4The pressure block 9 has an L-shaped structure, and the inner side of the long end of the pressure block 9 is pressed against the top of the pad block 10.

[0022] See Figure 3 The top of one end of the extension arm 5 is provided with a boss 13, and multiple pads 10 are stacked and pressed between the boss 13 and the pressing block 9.

[0023] See Figure 3 One end of the extension arm 5 has a boss 2 14 at its bottom, and multiple pads 2 11 are stacked and pressed between the top of the support leg 6 and the boss 2 14.

[0024] In use: Through the automated pressing process, the operator only needs to place the door to be pressed on the pressing table 2 and start the equipment. Then, the pressing frame 3 is hoisted to the top of the door to be pressed, and the pressing block 4 is adjusted to the appropriate position. At this time, the pressing frame 3 uses its own weight to press the edge of the door. Then, the swing cylinder 7 drives the swing arm 8 to drive the pressing block 9 to press down precisely, so that the pressing frame 3 applies even pressure to the edge of the door through the pressing block 4. This design not only eliminates the edge-sealing defects caused by uneven force in traditional manual operations, but also enables the equipment to quickly adapt to the pressing requirements of door edge-sealing of different thicknesses through the adjustable pad block 10 and pad block 21 system. At the same time, through the modular design of the pressing block 4 component, enterprises can complete the pressing process adjustment for new car models without replacing the entire set of equipment, which significantly reduces the production line transformation cost. The entire device realizes the automated pressing process of door edge-sealing, enabling rapid adaptation and precise pressing of different car models and different specifications of doors, reducing the frequency and difficulty of manual adjustment, thereby reducing production costs and improving production efficiency and product quality stability.
