Description

Technical Field

[0001] This utility model relates to the field of automotive sealing strip technology, specifically a guide groove following degree shaping tool. Background Technology

[0002] Automotive sealing strips are elastic sealing materials installed in the gaps between various parts of a car body. They are mainly used to fill gaps in areas such as doors, windows, sunroofs, engine compartments, and trunks, providing sound insulation, waterproofing, dustproofing, shock absorption, and heat insulation. They are indispensable functional components in automobile manufacturing, directly affecting driving comfort, vehicle durability, and safety. The rolling tools for automotive sealing strips are generally specially designed based on the cross-sectional shape of the sealing strip used in the car model and the thickness of the body sheet metal. The shape of the rolling rollers and the distance between the rollers are specifically designed. To ensure the stability of the rolling effect, the spacing of the rolling rollers is constant for the same part of the same car model. However, in actual use, this leads to poor interchangeability of rolling tools between different car models. Even for different parts of the same car model, different models of rolling tools are required, significantly increasing tool usage costs.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202422393159.6, application date 2024-09-30) provides an automotive sealing strip rolling tool, including a first rolling assembly, a second rolling assembly, and an adjusting assembly. The active roller assembly of the first rolling assembly is mounted on a base, and the base is provided with a power input end for connecting a power handle. The second rolling assembly includes a connecting seat and a driven roller assembly, forming a rolling channel between the driven roller assembly and the active roller assembly. The adjusting assembly is disposed between the base and the connecting seat and includes an adjusting screw, a nut, and an elastic component for applying preload to the nut. The base is provided with a first mounting hole, and the connecting seat is provided with a second mounting hole. The nut is disposed at the end of the second mounting hole, and the elastic component is located inside the second mounting hole. This automotive sealing strip rolling tool achieves adjustable spacing of the rolling channel, is suitable for the installation of sealing strips of different vehicle models, and improves the versatility of the rolling tool.

[0004] When installing automotive sealing strips, corner molds are generally used for pre-bending. However, this requires an additional mold or the replacement of aluminum strips with better conformability, which not only increases costs but also affects the punching process. In addition, the overall rigidity of the sealing strip decreases, which also affects the product itself. During use, the above-mentioned devices cannot ensure that the sealing strip fits tightly against the large-radius sheet metal, resulting in uneven stress on the sealing strip. Over long-term use, this will accelerate the aging of the sealing strip, shorten its service life, and increase maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a guide groove following degree shaping tool to solve the problem mentioned in the background art that the sealing strip cannot be tightly attached to the large arc sheet metal, resulting in uneven force on the sealing strip. In the long-term use, this will accelerate the aging of the sealing strip, shorten its service life, and increase maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide groove following-degree shaping fixture, comprising a base, wherein a limiting groove is formed inside the base, and a pneumatic component is fixedly connected to the lower right end of the base, and a movable frame is fixedly connected to the output end of the pneumatic component, while the movable frame is slidably disposed on the upper end of the base; a limiting strip is fixedly connected to the lower surface of the movable frame near one end of the base, and the limiting strip is symmetrically distributed about the center of the movable frame, and the limiting strip is slidably disposed on the surface of the limiting groove, while a high-strength spring steel is slidably connected to the inner wall of the movable frame; a fixing block is provided on the surface of the high-strength spring steel near one end of the movable frame through a locking component, and the fixing block is slidably disposed inside the movable frame.

[0007] Preferably, the engaging assembly includes a sliding groove formed inside the fixing block, and one end of a fixing spring is fixedly connected to the surface of the sliding groove.

[0008] Preferably, the other end of the fixing spring is fixedly connected to a connecting block, and the surface of the connecting block is inclined near the end of the movable frame.

[0009] Preferably, the connecting blocks are symmetrically distributed about the center of the fixed block, and the left end of the high-strength spring steel away from the movable frame is arc-shaped.

[0010] Preferably, the movable frame has a connecting groove inside, and the fixing block is slidably connected to the surface of the connecting groove.

[0011] Preferably, a baffle is fixedly connected to the outside of the movable frame, and a limit rod is fixedly connected to one end of the baffle near the movable frame, and a sliding block is slidably connected to the limit rod.

[0012] Preferably, the sliding block is slidably disposed inside the baffle, and a buffer spring is fixedly connected to one end of the sliding block surface away from the baffle, and the other end of the buffer spring is fixedly connected to the moving frame. At the same time, a force-bearing plate is fixedly connected to the end of the sliding block, and the force-bearing plate is slidably disposed on the surface of the connecting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the guide groove following-degree shaping fixture adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The guide groove following degree shaping tooling, through the setting of arc-shaped high-strength spring steel and pneumatic components, enables the sealing strip to perfectly fit the large arc sheet metal designed by the OEM, fundamentally eliminating assembly cracks caused by non-fitting, improving the overall appearance quality and sealing performance of the vehicle, while maintaining the overall rigidity of the sealing strip, and ensuring that other performance indicators such as surface difference are stable and qualified.

[0015] Furthermore, when the device is working, it can make the sealing strip locally bend while maintaining its rigidity, and then use the glossy finish to assemble the sealing strip to achieve the ideal curvature, which is low in cost and high in efficiency.

[0016] (2) The guide groove following degree shaping fixture, through the setting of sliding blocks and force plates, makes it convenient for workers to replace the arc-shaped high-strength spring steel, greatly reducing the downtime of production line changeover and debugging, and improving the overall efficiency of the equipment. At the same time, it can ensure the stability of the shaping action and the uniformity of product quality.

[0017] Furthermore, it can ensure the stability of the shaping process and the uniformity of product quality, reduce the number of defective products caused by product quality problems, and reduce production costs.

[0018] (3) The guide groove following degree shaping fixture, through the set limit groove and limit bar, can ensure the stable operation of the pneumatic components, effectively avoid the instability of operation caused by deviation, and make each shaping action highly consistent, which not only ensures the dimensional accuracy and shape accuracy of the parts, but also improves the product yield.

[0027] 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.

[0028] Example 1: By using the limiting groove 2, limiting strip 5, and base 1, the stability of the device during operation is improved, ensuring high consistency in each shaping action. Figures 1-3 As shown: It includes a base 1, with a limiting groove 2 inside the base 1, and a pneumatic component 3 is fixedly connected to the lower right end of the base 1. A movable frame 4 is fixedly connected to the output end of the pneumatic component 3. The movable frame 4 is slidably disposed on the upper end of the base 1. A limiting strip 5 is fixedly connected to the lower surface of the movable frame 4 near the end of the base 1. The limiting strip 5 is symmetrically distributed about the center of the movable frame 4 and is slidably disposed on the surface of the limiting groove 2. A high-strength spring steel 6 is slidably connected to the inner wall of the movable frame 4. A fixing block 7 is disposed on the surface of the high-strength spring steel 6 near the end of the movable frame 4 through a locking component. The fixing block 7 is slidably disposed inside the movable frame 4.

[0029] The worker places the sealing strip to be shaped on the upper surface of base 1, aligning the area to be shaped with the pressing position on the surface of high-strength spring steel 6 (e.g., Figure 1 and Figure 2 As shown), after the workers have installed the sheet metal and sealing strip, they start the pneumatic assembly 3. The pneumatic assembly 3 pushes the moving frame 4 to slide horizontally along the base 1, and the limiting strip 5 slides in the limiting groove 2, constraining the movement trajectory of the moving frame 4 to be a straight line, ensuring the processing accuracy of the device. The high-strength spring steel 6 is pressed vertically against the sealing strip (as shown) under the push of the moving frame 4. Figure 3 As shown in the figure, the sealing strip can perfectly fit the large-radius sheet metal designed by the OEM, fundamentally eliminating assembly cracks caused by non-fitting, improving the overall appearance quality and sealing performance of the vehicle, while maintaining the overall rigidity of the sealing strip, and ensuring that other performance indicators such as surface difference are stable and qualified.

[0030] In Example 2, unlike Example 1, the fixed spring 9, sliding groove 8, and connecting block 10 enable the sealing strip to perfectly fit the large-radius sheet metal designed by the OEM, fundamentally eliminating assembly cracks caused by misfitting. Figures 4-5 As shown: The engaging assembly includes a sliding groove 8 opened inside the fixed block 7, and one end of a fixed spring 9 is fixedly connected to the surface of the sliding groove 8. The other end of the fixed spring 9 is fixedly connected to a connecting block 10, and the surface of the connecting block 10 is inclined at the end near the moving frame 4. The connecting blocks 10 are symmetrically distributed about the center of the fixed block 7, and the left side of the high-strength spring steel 6 away from the moving frame 4 is arc-shaped.

[0031] When the worker installs the high-strength spring steel 6, the worker pushes the fixing block 7 on the surface of the high-strength spring steel 6 to slide it onto the surface of the connecting groove 11 opened inside the moving frame 4 (as shown). Figure 3 As shown), when the connecting block 10 on the outer side of the fixed block 7 contacts the movable frame 4, because the surface of the connecting block 10 is inclined, the movable frame 4 pushes the connecting block 10 to slide on the surface of the sliding groove 8 opened inside the fixed block 7, and at the same time causes the fixing spring 9 on the surface of the connecting block 10 to retract towards the inner wall of the fixed block 7 (as shown). Figure 4 As shown, when the high-strength spring steel 6 is tightly fitted with the movable frame 4, the fixed spring 9 pushes the connecting block 10 to slide onto the surface of the connecting groove 11, making the connecting block 10 and the connecting groove 11 tightly fitted, thereby achieving the connection between the high-strength spring steel 6 and the movable frame 4. The high-strength spring steel 6 can fundamentally eliminate assembly cracks caused by non-fitting, improve the overall appearance quality and sealing of the vehicle, while maintaining the overall rigidity of the sealing strip, and also ensuring that other performance indicators such as surface difference are stable and qualified.

[0032] In Example 3, unlike Example 2, the use of a limiting rod 13, a sliding block 14, and a buffer spring 16 facilitates the replacement of the arc-shaped high-strength spring steel 6 by workers, greatly reducing downtime for production line changeovers and adjustments. Figures 6-7 As shown: The movable frame 4 has a connecting groove 11 inside, and a fixing block 7 is slidably connected to the surface of the connecting groove 11. A baffle 12 is fixedly connected to the outside of the movable frame 4, and a limit rod 13 is fixedly connected to one end of the surface of the baffle 12 near the movable frame 4. A sliding block 14 is slidably connected to the limit rod 13. The sliding block 14 is slidably disposed inside the baffle 12, and a buffer spring 16 is fixedly connected to one end of the surface of the sliding block 14 away from the baffle 12. The other end of the buffer spring 16 is fixedly connected to the movable frame 4. At the same time, a force plate 15 is fixedly connected to the end of the sliding block 14. The force plate 15 is slidably disposed on the surface of the connecting groove 11.

[0033] When the worker is maintaining the high-strength spring steel 6, the worker presses the sliding block 14 on the outside of the movable frame 4, causing the sliding block 14 to rotate inside the baffle 12 (e.g., Figure 6 As shown), and the buffer spring 16 on the surface of the sliding block 14 retracts outward from the moving frame 4. As the sliding block 14 moves, the force plate 15 at the end contacts the connecting block 10 (as shown). Figure 7 As shown in the figure, the connecting block 10 is pushed to slide into the inner wall of the fixed block 7. When the connecting block 10 is completely inside the fixed block 7, the worker pulls the high-strength spring steel 6. The high-strength spring steel 6 drives the fixed block 7 to slide on the surface of the connecting groove 11, thereby separating the high-strength spring steel 6 from the moving frame 4. This greatly reduces the downtime of production line changeover and debugging, and improves the overall efficiency of the equipment. At the same time, it can ensure the stability of the shaping action and the uniformity of product quality.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
