Description
Technical Field
[0001] The utility model relates to the technical field of automobile sealing strip assembly, in particular to a rolling tool for automobile sealing strips. Background Art
[0002] Automobile sealing strips are generally used to fill the gaps or clearances between the components of the vehicle body and have functions such as shock absorption, waterproofing, dustproofing, and sound insulation. For example, sealing strips are assembled at the body door opening or the trunk to improve the sealing effect of the vehicle. In order to ensure that the manually assembled automobile sealing strips meet the process requirements, assembly workers usually use a rolling tool to roll the manually installed automobile sealing strips, so as to ensure that the sealing strips and the body sheet metal are fully adhered, and improve the installation effect of the automobile sealing strips.
[0003] At present, the rolling tools for automobile sealing strips are generally designed with the shape of the rolling shaft rollers and the spacing between the rolling shafts according to the cross-sectional shape of the sealing strips used for the vehicle model and the thickness of the body sheet metal. In particular, for the design of the spacing between the rolling shafts, in order to ensure the stability of the rolling effect, the spacing between the rolling shafts of the rolling tool for the same part of the same vehicle model is constant. That is to say, in actual use, a single vehicle model has a dedicated rolling tool, resulting in poor interchangeability of the rolling tools between different vehicle models. Even for rolling operations at different parts of the same vehicle model, different models of rolling tools need to be equipped. In this way, the rolling tools lack versatility and greatly increase the tool usage cost. Summary of the Invention
[0004] The purpose of the utility model is to provide a rolling tool during the process of assembling automobile sealing strips for a vehicle, which can realize the adjustable spacing of the rolling channels, make it applicable to the installation of sealing strips of different vehicle models, and improve the versatility of the rolling tool.
[0005] To achieve the above purpose, the utility model adopts the following scheme:
[0006] A rolling tool for automobile sealing strips includes a first rolling assembly and a second rolling assembly. A rolling channel for clamping the automobile sealing strip is formed between the first rolling assembly and the second rolling assembly, and an adjusting assembly for adjusting the spacing of the rolling channel is further included;
[0007] The first rolling assembly includes a base and a driving rolling shaft assembly. The driving rolling shaft assembly is installed on the base. A power input end for connecting a power handle is arranged on the base, and the rotating shaft of the driving rolling shaft assembly is connected to the power handle;
[0008] The second rolling component includes a connecting seat and a driven roller assembly. The driven roller assembly is arranged parallel to the driving roller assembly. A rolling channel is formed between the driven roller assembly and the driving roller assembly. The driven roller assembly is installed on the connecting seat.
[0009] The adjusting component is arranged between the base and the connecting seat. The adjusting component includes an adjusting screw, a nut, and an elastic component for applying a pre-tightening force to the nut.
[0010] A first mounting hole for passing the adjusting screw is provided on the base. A second mounting hole for matching the first mounting hole is provided on the connecting seat. The nut is arranged at the end of the second mounting hole. The end of the adjusting screw is screwed with the nut. The elastic component is located in the second mounting hole. A pressing end surface for contacting the nut is provided on the elastic component.
[0011] Wherein, the distance between the rolling channels is adjusted by the adjusting component to adapt to the sealing strip assembly working conditions of various vehicle models. The adjusting component changes the distance between the rolling channels by rotating the adjusting screw. When the adjusting screw is rotated, the screwing depth of the adjusting screw in the nut changes. The second mounting hole restricts the movement of the nut, so that the adjusting screw drives the connecting seat to displace relative to the base, and thus the driven roller assembly displaces relative to the driving roller assembly. Rotating the adjusting screw will move the driven roller assembly along the adjusting direction, increasing or decreasing the distance between the two roller assemblies. The elastic component provides a pre-tightening force during the adjustment to ensure that the screwing between the adjusting screw and the nut is tight and stable.
[0012] Preferably, a limiting groove is provided at one end of the second mounting hole close to the second mounting hole, and a clamping groove is provided at the other end of the second mounting hole. The nut is embedded in the clamping groove, and the elastic component is arranged in the limiting groove.
[0013] Preferably, the driving roller assembly further includes a roller. The roller is sleeved at the end of the rotating shaft. The roller and the rotating shaft are connected by a fastener.
[0014] Preferably, anti-slip grooves are provided on the side wall of the roller.
[0015] Preferably, a transmission mechanism is provided between the driving roller assembly and the driven roller assembly. The rotating shaft of the driving roller assembly is connected to the rotating shaft of the driven roller assembly through the transmission mechanism.
[0016] Preferably, the rotating direction of the rotating shaft of the driven roller assembly is opposite to the rotating direction of the rotating shaft of the driving roller assembly.
[0017] Preferably, a pressing mechanism is further provided on the base. The pressing mechanism includes a bracket and a pressing wheel. The pressing wheel is arranged outside the rolling channel. The pressing wheel is installed on the base through the bracket.
[0018] Preferably, the axis of the pressing wheel is arranged perpendicular to the rotating shaft of the driving roller assembly, and the side wall of the pressing wheel is conical.
[0019] Compared with the prior art, the automotive sealing strip rolling tool provided by the present utility model has the following substantial features and improvements: The automotive sealing strip rolling tool adjusts the spacing of the rolling channel through the adjusting assembly, and can adapt to the assembly requirements of sealing strips of various vehicle models. Whether it is a sealing strip with different thicknesses or a sealing strip with a special shape, it can be efficiently processed through simple adjustment operations, greatly improving the versatility of the rolling tool. The adjusting assembly drives the relative displacement between the connecting seat and the base by changing the screwing depth of the adjusting screw and the nut, causing the driven roller assembly to generate a corresponding displacement relative to the driving roller assembly, achieving precise spacing control and ensuring the rolling effect. Moreover, during the adjustment process, the elastic component provides a preloading force, ensuring that the screwing between the adjusting screw and the nut is tight and stable. Whether during the adjustment process or during the rolling operation, the spacing of the rolling channel can remain stable, avoiding loosening or spacing changes caused by vibration or external forces, thereby ensuring the rolling quality of the sealing strip.

Detailed implementation manners
[0028] The following will describe in detail the specific implementation manners of the present utility model with reference to the drawings.
[0029] As Figures 1-7 shown, in the embodiment of the present utility model, a rolling tool for automotive sealing strips is proposed, aiming to achieve adjustable spacing between the rolling shafts of the rolling tool during the assembly of automotive sealing strips for vehicles, so as to be applicable to the installation of sealing strips of different vehicle models and improve the versatility of the rolling tool.
[0030] The rolling tool for automotive sealing strips proposed in the embodiment of the present utility model adjusts the spacing of the rolling channel through the adjusting assembly, and can adapt to the assembly requirements of sealing strips of various vehicle models. Whether it is a sealing strip with different thicknesses or a sealing strip with a special shape, it can be efficiently processed through simple adjustment operations, greatly improving the versatility of the rolling tool. The adjusting assembly changes the relative displacement between the connecting seat and the base by the screwing depth of the adjusting screw and the nut, so that the driven roller assembly generates a corresponding displacement relative to the driving roller assembly, realizing precise spacing control, ensuring the rolling effect, achieving adjustable spacing of the rolling channel, being applicable to the installation of sealing strips of different vehicle models, improving the versatility of the rolling tool, and greatly reducing the use cost of the rolling tool.
[0031] As Figure 1 Combined with Figure 2 shown, a rolling tool for automotive sealing strips includes a first rolling assembly 1 and a second rolling assembly 2. A rolling channel 3 for clamping the automotive sealing strip is formed between the first rolling assembly 1 and the second rolling assembly 2. Combined with Figure 4 shown, the rolling tool further includes an adjusting assembly 4 for adjusting the spacing of the rolling channel 3.
[0032] As Figure 3 Combined with Figure 4 shown, the first rolling assembly 1 includes a base 11 and a driving roller assembly 12. The driving roller assembly 12 is installed on the base 11. A power input end for connecting the power handle 6 is provided on the base 11. The rotating shaft 122 of the driving roller assembly 12 is connected to the power handle 6. For example, the power handle 6 can be an electric handle or a pneumatic handle according to the on-site assembly conditions of the automotive sealing strip.
[0033] As shown Figure 3 in FIG. 2, the second rolling assembly 2 includes a connecting seat 21 and a driven roller assembly 22. The driven roller assembly 22 is arranged parallel to the driving roller assembly 12. A rolling channel 3 is formed between the driven roller assembly 22 and the driving roller assembly 12, and the driven roller assembly 22 is mounted on the connecting seat 21.
[0034] As shown Figure 4 in FIG. 3, the adjusting assembly 4 is arranged between the base 11 and the connecting seat 21. The adjusting assembly 4 includes an adjusting screw 41, a nut 42, and an elastic member 43 for applying a pre-tightening force to the nut 42. A first mounting hole 13 for passing through the adjusting screw 41 is provided on the base 11. A second mounting hole 23 for matching the first mounting hole 13 is provided on the connecting seat 21. The nut 42 is arranged at the end of the second mounting hole 23. The end of the adjusting screw 41 is screwed with the nut 42. The elastic member 43 is located in the second mounting hole 23. A pressing end surface for contacting the nut 42 is provided on the elastic member 43.
[0035] Among them, the adjusting assembly 4 changes the spacing of the rolling channel 3 by rotating the adjusting screw 41. When the adjusting screw 41 is screwed and rotated, the screwing depth of the adjusting screw 41 in the nut 42 changes. The second mounting hole 23 restricts the movement of the nut 42, so that the adjusting screw 41 drives the connecting seat 21 to displace relative to the base 11, and thus the driven roller assembly 22 displaces relative to the driving roller assembly 12. The elastic member 43 provides a pre-tightening force during the adjustment process to ensure the tight and stable screwing between the adjusting screw 41 and the nut 42. For example, the elastic member 43 is selected as a compression spring, and the compression spring is coaxially sleeved on the adjusting screw 41. The cross-section of the spring wire of the compression spring is selected as circular or rectangular.
[0036] As shown Figure 4 in FIG. 4, a limiting groove 24 is provided at one end of the second mounting hole 23 close to the second mounting hole 23. A clamping groove 25 is provided at the other end of the second mounting hole 23. The nut 42 is embedded in the clamping groove 25. The elastic member 43 is arranged in the limiting groove 24. With such an arrangement, the nut 42 can be stably embedded in the clamping groove 25, avoiding its axial displacement during the adjustment process, ensuring the more stable screwing between the adjusting screw 41 and the nut 42, and further improving the accuracy of the spacing adjustment of the rolling channel 3. The elastic member 43 is arranged in the limiting groove 24 and can provide a continuous pre-tightening force during the adjustment process. This pre-tightening force not only ensures the tight screwing between the adjusting screw 41 and the nut 42, but also can absorb part of the vibration and impact, further improving the stability of the entire adjusting assembly 4.
[0037] In addition, the design of embedding the nut 42 into the card slot 25 and arranging the elastic component 43 in the limiting slot 24 is also beneficial to keeping the adjusting component 4 tightly combined during frequent adjustment processes, avoiding loosening of the adjusting screw 41.
[0038] As Figure 3 shown, a pressing mechanism 5 is further provided on the base 11. The pressing mechanism 5 includes a bracket 51 and a pressing wheel 52. The pressing wheel 52 is arranged outside the rolling channel 3. The pressing wheel 52 is installed on the base 11 through the bracket 51. The pressing wheel 52 is used to apply a pressing force to the edge of the automotive sealing strip, thereby further ensuring the installation effect of the automotive sealing strip.
[0039] Among them, the additional pressing force applied by the pressing mechanism 5 through the pressing wheel 52 can ensure that the sealing strip is fully compacted during the installation process, not only ensuring good contact between the sealing strip and the vehicle body, but also preventing problems such as air leakage and water ingress caused by loosening of the sealing strip during future use, thus greatly improving the sealing effect.
[0040] For example, the axis of the pressing wheel 52 is arranged perpendicular to the rotating shaft 122 of the active roller assembly 12, and the side wall of the pressing wheel 52 is conical. In this way, the design of the pressing wheel 52 can evenly distribute the pressing force, avoiding damage to the sealing strip caused by concentrated pressure, not only ensuring the appearance quality of the sealing strip, but also extending its service life and reducing the frequency of replacement and maintenance. The design of the conical side wall enables the pressing wheel 52 to better adapt to sealing strips of different shapes and sizes. Whether the edge of the sealing strip is straight, curved or irregular, the conical pressing wheel 52 can provide a good pressing effect, expanding the applicable range of the rolling tool.
[0041] As Figure 4 shown, the active roller assembly 12 further includes a roller 121. The roller 121 is sleeved on the end of the rotating shaft 122. The roller 121 and the rotating shaft 122 are connected by fasteners. With such a setting, the roller 121 and the rotating shaft 122 are connected by fasteners, making the disassembly and assembly process more convenient. The operator can easily perform the maintenance and replacement of the roller 121, reducing the maintenance time and labor intensity and improving the production efficiency.
[0042] For example, anti-slip grooves are provided on the side wall of the roller 121. The design of the anti-slip grooves increases the friction on the surface of the roller 121, ensuring closer contact between the sealing strip and the roller 121 during the rolling process, effectively preventing the automotive sealing strip from sliding or shifting during the rolling process, and improving the stability and accuracy of the installation.
[0043] In order to further reduce the maintenance difficulty of the rolling tool, the driven roller assembly 22 has a similar structural design to the active roller assembly 12.
[0044] A transmission mechanism is provided between the active roller assembly 12 and the driven roller assembly 22, and the rotating shaft 122 of the active roller assembly 12 is connected to the rotating shaft 122 of the driven roller assembly 22 through the transmission mechanism. With such a setting, through the connection of the transmission mechanism, the active roller assembly 12 and the driven roller assembly 22 can achieve synchronous rolling, ensuring that the force and movement of the automotive sealing strip between the two are consistent, and preventing the sealing strip from being stretched, twisted or displaced during the rolling process, further improving the installation accuracy.
[0045] For example, the rotation direction of the rotating shaft 122 of the driven roller assembly 22 is opposite to the rotation direction of the rotating shaft 122 of the active roller assembly 12. In this way, it is beneficial to improve the power output during the rolling process, increase the rolling speed of the rolling tool, and thus improve the installation efficiency of the automotive sealing strip.
[0046] As Figure 5 shown, an adjusting assembly 4 in an automotive sealing strip rolling tool proposed in an embodiment of the present invention can also be arranged externally to further reduce the maintenance difficulty of the rolling tool.
[0047] When an automotive sealing strip rolling tool proposed in an embodiment of the present invention is in use, as Figure 5 combined with Figure 6 shown, this automotive sealing strip rolling tool can select a matching power handle 6 structure according to different assembly positions. For example, Figure 5 shown, when assembling the sealing strip on the body door opening, according to the spatial layout of the assembly station, in order to further facilitate the hand-held operation of the assembly personnel, the rotating shaft 122 of the active roller assembly 12 and the output shaft of the power handle 6 are arranged coaxially. As Figure 6 shown, when assembling the sealing strip at the automotive trunk, according to the spatial layout of the assembly station, the rotating shaft 122 of the active roller assembly 12 and the output shaft of the power handle 6 are arranged in an L-shaped structure, which is beneficial to reducing the difficulty of the rolling tool at the turning point of the trunk.
[0048] An automotive sealing strip rolling tool provided in an embodiment of the present invention adjusts the spacing of the rolling channel 3 through the adjusting assembly 4 to adapt to the sealing strip assembly working conditions of various vehicle models. The adjusting assembly 4 uses a rotating adjusting screw 41 to change the spacing of the rolling channel 3. When the adjusting screw 41 is rotated, the screwing depth of the adjusting screw 41 in the nut 42 changes. The second mounting hole 23 restricts the movement of the nut 42, and then the adjusting screw 41 drives the connecting seat 21 to displace relative to the base 11, so that the driven roller assembly 22 displaces relative to the active roller assembly 12, realizing the adjustable spacing of the rolling channel 3, making it applicable to the installation of sealing strips of different vehicle models and improving the versatility of the rolling tool.
[0049] The utility model is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the utility model can also have other implementation manners. For those skilled in the art, any technical solutions formed by making any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
