Description

Technical Field

[0001] This utility model relates to the field of trim pressing technology, and in particular to a pre-pressing device for trim assembly. Background Technology

[0002] A trim strip pre-pressing device, a specialized piece of equipment for assembling decorative parts, primarily achieves functions such as rapid gripping, precise positioning, and preliminary pressing and fixing of trim strips. This effectively ensures uniform assembly gaps and firm adhesion between the trim strip and the product body, enhancing the overall appearance and refinement of the product. Publication number CN211072509U discloses an aluminum alloy trim strip pressing device, relating to the field of trim strip pressing technology. It includes a worktable and an auxiliary frame. The upper end of the trim strip mounting plate has an mounting groove for mounting a trim strip body that is wider at the top and narrower at the bottom. The piston rod of the cylinder at the top of the reinforcing plate passes through the reinforcing plate and connects to the upper middle part of the pressure plate. The lower end of the L-shaped plate is also connected to a vertical rod. The connecting seats at both ends of the auxiliary frame are movably connected to one end of a horizontal plate. The middle part of the horizontal plate is movably connected to a support seat at the upper end of the worktable. The open slot... The bottom of the front and rear side walls of this invention is connected to several sets of elastic inclined plates for insertion into the mounting groove. These elastic inclined plates are inserted into the mounting groove, facilitating accurate pressing of the trim strip body into the groove under their action. Simultaneously, as the pressure plate presses down on the trim strip body, the auxiliary frame moves upward, and the elastic inclined plates leave the mounting groove, further facilitating the pressing of the trim strip body into the groove. This invention, by setting up elastic inclined plates and an auxiliary frame, allows for quick positioning and facilitates pressing the trim strip body into the mounting groove. However, when faced with mounting plates of different widths and shapes, it cannot quickly fix the mounting plates, causing them to easily shift or tilt during the pressing process. This affects the alignment accuracy between the trim strip body and the mounting groove, resulting in trim strip misalignment, uneven assembly gaps, trim strip damage, or mounting plate deformation, impacting production efficiency and requiring improvement. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a pre-pressing device for assembling decorative strips, including a base, a clamping seat fixedly installed on the surface of the base, an installation block placed on the surface of the clamping seat, a clamping motor fixedly installed on the surface of the clamping seat, a clamping screw fixedly installed at the output end of the clamping motor, a clamping slide rod fixedly installed inside the clamping seat, a clamping mechanism threadedly connected to the surface of the clamping screw, a moving motor fixedly installed on the surface of the base, a moving screw fixedly installed at the output end of the moving motor, a moving slide rod fixedly installed inside the base, a screw rod frame threadedly connected to the surface of the moving screw, a lifting motor fixedly installed on the surface of the screw rod frame, a lifting screw fixedly installed at the output end of the lifting motor, a lifting screw block threadedly connected to the surface of the lifting screw block, a limit plate fixedly installed on the surface of the lifting screw block, a lifting slider fixedly installed on the surface of the limit plate, a slide rod frame slidably connected to the surface of the moving slide rod, and a lifting slide rod fixedly installed inside the slide rod frame.

[0005] Preferably, the clamping mechanism includes a clamping screw block, a clamping plate, a clamping slider, and a clamping pad. The clamping plate is fixedly mounted on the surface of the clamping screw block, and the clamping slider and clamping pad are fixedly mounted on the surface of the clamping plate. Here, the clamping screw block cooperates with the clamping lead screw to achieve precise drive, ensuring that the clamping force of the clamping plate on the mounting block is controllable. The clamping slider slides along the clamping slide bar to ensure stable clamping without deviation. The clamping pad is made of elastic material, which can both enhance friction to prevent the mounting block from sliding and avoid damage to the workpiece surface caused by rigid contact. This achieves the dual effect of stable clamping and workpiece protection, and improves the positioning accuracy during pre-pressing.

[0006] Preferably, the lead screw bracket and the slide bracket are of the same length and symmetrically distributed on both sides of the limiting plate, with the limiting plate located directly above the mounting block. Here, the consistent length and symmetrical distribution of the lead screw bracket and slide bracket provide balanced support for the limiting plate, preventing tilting or wobbling due to uneven force and ensuring a stable posture during movement and lifting. Furthermore, the precise positioning of the limiting plate directly above the mounting block ensures that the pressure plate accurately applies to the trim assembly position on the mounting block during subsequent pre-pressing operations, preventing pressing misalignment and effectively improving the accuracy and consistency of pre-pressing, thus reducing the probability of defective products.

[0007] Preferably, the movable lead screw and the movable slide rod are symmetrically distributed on both sides of the base, and the interior of the lifting slider and the surface of the lifting slide rod are slidably connected. Here, the symmetrical distribution of the movable lead screw and the movable slide rod on both sides of the base allows for more balanced force distribution and a smoother movement trajectory when the lead screw frame and slide rod frame move the limiting plate, avoiding offset or jamming caused by unilateral force. The symmetrical structure improves the overall stability of the device and reduces the risk of component deformation after long-term use. The sliding cooperation between the lifting slider and the lifting slide rod provides precise guidance for the lifting movement of the limiting plate, ensuring that the limiting plate always moves in a vertical direction, avoiding tilting during lifting, further ensuring the alignment accuracy of the pressure plate and the mounting block during pre-pressing, and improving the pressing quality.

[0008] Preferably, the surface of the limiting plate is provided with a sliding groove, the surface of the sliding groove is provided with a spring groove, a spring is fixedly installed on the surface of the spring groove, a pressure plate is fixedly installed on the other end of the spring, and a rubber pad is fixedly installed on the surface of the pressure plate. Here, the sliding groove provides reasonable space for the movement of the pressure plate. When the limiting plate approaches and fits against the mounting plate, the pressure plate can flexibly adjust its position along the sliding groove to avoid hard scraping against the surface of the mounting plate. The spring has good elastic buffering performance, which can offset part of the downward impact force at the moment the limiting plate fits against the mounting plate, preventing indentations or wear on the surface of the mounting plate due to excessive pressure. The rubber pad on the surface of the pressure plate is made of a soft and wear-resistant material. When in direct contact with the mounting plate, it can increase the contact area to disperse pressure and isolate friction from hard objects through its own material properties, protecting the surface of the mounting plate and ensuring a tighter fit of the trim assembly.

[0009] Preferably, there are two spring grooves symmetrically distributed on both sides of the slide groove, and the side of the pressure plate can be slidably connected to the surface of the slide groove through the extension and contraction of the spring. Here, the symmetrically distributed spring grooves allow the spring force applied to the pressure plate to be more even, preventing the pressure plate from tilting due to force on one side, ensuring that the pressure plate and the mounting plate always maintain a stable fit when in contact, and reducing wear on the mounting plate caused by excessive local pressure. The design of the side of the pressure plate being slidably connected to the slide groove through the extension and contraction of the spring ensures that the pressure plate can move smoothly along the slide groove when under pressure, avoiding jamming and scratching the mounting plate, and also allows the pressure of the pressure plate on the mounting plate to be evenly distributed through the synchronous extension and contraction of the spring. While protecting the surface of the mounting plate, it also makes the pre-pressing of the trim strip tighter and flatter, improving the overall assembly quality.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a clamping screw, a clamping plate, a moving screw, a lifting screw, and a limiting plate, the synergistic effect of these structures allows the clamping screw to drive the clamping plate to move smoothly along the clamping slide bar, quickly clamping and fixing the mounting block, providing a stable workpiece base for pressing. The moving screw rotates under the action of the moving motor, cooperating with the moving slide bar to guide the screw frame and slide bar frame to move synchronously, driving the limiting plate to be accurately adjusted to the pressing position directly above the mounting block. The lifting screw operates under the drive of the lifting motor, causing the lifting screw block to drive the limiting plate to descend vertically along the lifting slide bar, achieving the effect of accurate positioning, uniform pressure, and efficient operation in the pre-pressing of the trim strip, improving assembly consistency and production efficiency.

[0011] 2. In this utility model, by setting up a sliding groove, a spring groove, a spring, a pressure plate, and a rubber pad, the synergistic effect of these structures is utilized. The spring groove ensures the precise transmission of its elastic force. When the limiting plate is pressed down, the spring is first compressed to avoid hard pressure damage to the mounting plate. The pressure plate slides smoothly along the sliding groove to ensure that the contact surface with the mounting plate is always flat, preventing uneven local force from causing indentations. The rubber pad is in direct contact with the mounting plate, which not only isolates the friction of hard objects through soft material to avoid surface wear, but also increases the contact friction force, making it difficult for the trim strip to shift during pressing. Ultimately, the dual goals of protecting the workpiece and improving pressing stability are achieved. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1 Please see Figure 1-4This utility model provides a technical solution: a pre-pressing device for assembling decorative strips, including a base 1 to ensure the stability of the overall structure of the device, prevent displacement of components during operation due to unstable foundation, and ensure smooth pre-pressing operation. A clamping seat 2 is fixedly installed on the surface of the base 1, and an installation block 3 is placed on the surface of the clamping seat 2. A clamping motor 4 is fixedly installed on the surface of the clamping seat 2, and a clamping screw 5 is fixedly installed at the output end of the clamping motor 4. A clamping slide rod 6 is fixedly installed inside the clamping seat 2, and a clamping mechanism is threadedly connected to the surface of the clamping screw 5. The clamping mechanism includes a clamping screw block 7, a clamping plate 8, a clamping slider 9, and a clamping pad 10. The clamping plate 8 is fixedly installed on the surface of the clamping screw block 7, and the clamping slider 9 is fixedly installed on the surface of the clamping plate 8. The clamping pad 10, along with the clamping screw block 7 and the clamping lead screw 5, achieves precise drive, ensuring that the clamping force of the clamping plate 8 on the mounting block 3 is controllable. The clamping slider 9 slides along the clamping slide bar 6, ensuring stable clamping without deviation. The clamping pad 10 is made of elastic material, which can enhance friction to prevent the mounting block 3 from sliding, and avoid damage to the workpiece surface caused by rigid contact, achieving the dual effect of stable clamping and workpiece protection, and improving the positioning accuracy during pre-pressing. A moving motor 11 is fixedly installed on the surface of the base 1, and a moving lead screw 12 is fixedly installed at the output end of the moving motor 11. A moving slide bar 13 is fixedly installed inside the base 1, and a lead screw frame 14 is threadedly connected to the surface of the moving lead screw 12. The lead screw frame 14 and the slide bar frame 20 have the same length and are aligned. The screw rods 14 and 20 are distributed on both sides of the limiting plate 18, which is located directly above the mounting block 3. Here, the screw rod 14 and 20 are of the same length and symmetrically distributed, providing balanced support for the limiting plate 18 and preventing it from tilting or wobbling due to uneven force. This ensures that the limiting plate 18 maintains a stable posture during movement and lifting. The precise positioning of the limiting plate 18 directly above the mounting block 3 ensures that the pressure plate 25 can accurately act on the trim assembly position on the mounting block 3 during subsequent pre-pressing operations, avoiding pressing offset due to alignment deviation. This effectively improves the accuracy and consistency of pre-pressing and reduces the probability of defective products. A lifting motor 15 is fixedly installed on the surface of the screw rod 14, and a lifting screw rod 16 is fixedly installed at the output end of the lifting motor 15. The surface of the lowering screw 16 is threadedly connected to a lifting screw block 17. A limit plate 18 is fixedly installed on the surface of the lifting screw block 17. A lifting slider 19 is fixedly installed on the surface of the limit plate 18. A slider frame 20 is slidably connected to the surface of the movable slider 13. A lifting slider 21 is fixedly installed inside the slider frame 20. The movable screw 12 and the movable slider 13 are symmetrically distributed on both sides of the base 1. The interior of the lifting slider 19 and the surface of the lifting slider 21 are slidably connected. Here, the movable screw 12 and the movable slider 13 are symmetrically distributed on both sides of the base 1, which allows the screw frame 14 and the slider frame 20 to have more balanced force and a smoother movement trajectory when moving the limit plate 18, avoiding deviation or jamming caused by unilateral force. The symmetrical structure can improve the overall stability of the device.To reduce the risk of component deformation after long-term use, the sliding engagement between the lifting slider 19 and the lifting rod 21 provides precise guidance for the lifting movement of the limiting plate 18, ensuring that the limiting plate 18 always moves vertically and avoiding tilting during lifting. This further ensures the alignment accuracy between the pressure plate 25 and the mounting block 3 during pre-pressing, improving the pressing quality.

[0017] Example 2 Please see Figure 5 The limiting plate 18 has a groove 22 on its surface to guide the movement of the pressure plate 25. When the limiting plate 18 approaches and fits against the mounting plate, the pressure plate 25 can flexibly adjust its position along the groove 22 to avoid hard friction with the surface of the mounting plate, while ensuring that the pressure plate 25 can fit smoothly against the mounting plate. The groove 22 has a spring groove 23 on its surface, and a spring 24 is fixedly installed on the surface of the spring groove 23. The other end of the spring 24 is fixedly installed with the pressure plate 25, and a rubber pad 26 is fixedly installed on the surface of the pressure plate 25. Here, the slide groove 22 provides reasonable space for the movement of the pressure plate 25. When the limiting plate 18 approaches and fits against the mounting plate, the pressure plate 25 can flexibly adjust its position along the slide groove 22 to avoid hard friction with the surface of the mounting plate. The spring 24 has good elastic buffering performance and can offset part of the downward impact force at the moment the limiting plate 18 fits against the mounting plate, preventing indentations or wear on the surface of the mounting plate due to excessive pressure. The rubber pad 26 on the surface of the pressure plate 25 is made of a soft and wear-resistant material and directly contacts the mounting plate. When the plates come into contact, the contact area is increased to distribute pressure, and the material properties of the plate itself isolate it from friction with hard objects, protecting the surface of the mounting plate and ensuring a tighter fit of the trim. There are two spring grooves 23 symmetrically distributed on both sides of the slide groove 22. The side of the pressure plate 25 can slide between the extension and retraction of the spring 24 and the surface of the slide groove 22. Here, the symmetrically distributed spring grooves 23 allow the spring force applied by the spring 24 to the pressure plate 25 to be more even, preventing the pressure plate 25 from tilting due to unilateral force and ensuring the tightness of the pressure plate 25. 5. When in contact with the mounting plate, it always maintains a stable fit, reducing wear on the mounting plate caused by excessive local pressure. The design of the pressure plate 25 slidingly connected to the slide groove 22 through the extension and retraction of the spring 24 ensures that the pressure plate 25 can move smoothly along the slide groove 22 when under pressure, avoiding jamming and scratching the mounting plate. At the same time, the synchronous extension and retraction of the spring 24 allows the pressure of the pressure plate 25 on the mounting plate to be evenly distributed. While protecting the surface of the mounting plate, it also makes the pre-pressing of the trim strip tighter and flatter, improving the overall assembly quality.

[0018] Working principle: When faced with mounting blocks 3 of different widths and shapes, it is necessary to quickly fix the mounting blocks 3 to prevent them from shifting or tilting during the pressing process, which would affect the alignment accuracy between the trim body and the mounting groove, and cause damage to the trim or deformation of the mounting plate. In case of damage to the trim or deformation of the mounting plate, the mounting block 3 is placed on the clamping seat 2, and the clamping motor 4 is started. The clamping motor 4 drives the clamping screw 5, causing the clamping screw block 7 to move the clamping plate 8 along the clamping slide rod 6. The clamping pad 10 clamps and fixes the mounting block 3 to prevent it from shifting or tilting during the pressing process. The moving motor 11 is then started, causing the moving screw 12 to rotate. The frame 14 and the slide bar frame 20 move along the movable slide bar 13, sending the limiting plate 18 directly above the mounting block 3. The lifting motor 15 is started, and the lifting motor 15 drives the lifting screw 16 to make the lifting screw block 17 drive the limiting plate 18 to descend vertically along the lifting slide bar 21. When the limiting plate 18 approaches the mounting block 3, the pressure plate 25 contacts the mounting block 3 first, the spring 24 buffers the pressure, the pressure plate 25 is finely adjusted along the slide groove 22, and the rubber pad 26 directly adheres to the mounting block 3. Through the coordinated action of various structures, the trim body and the mounting groove are accurately aligned, avoiding problems such as pressing offset, uneven assembly gap, damage to the trim, and deformation of the mounting block 3, thus completing the pre-pressing operation.
