Description

Technical Field

[0001] This utility model relates to the field of automobile roof manufacturing technology, and in particular to a support mechanism and a roof waterjet cutting fixture. Background Technology

[0002] With the rapid development of the automotive industry, consumers' demands for personalized, lightweight, and environmentally friendly automotive interiors are increasing, leading to a significant increase in the complexity and precision requirements of interior components. Waterjet cutting technology, with its advantages of no thermal deformation, smooth cuts, and strong material adaptability, has been widely applied in the processing of automotive interior components (such as dashboards, door panels, and pillar trim), becoming one of the key processes for achieving complex shape cutting.

[0003] Waterjet cutting fixtures are crucial tooling for supporting products during waterjet cutting. The front and rear edges of a wet two-step roof require fabric edging, with key steps including: punching the front and rear edges of the substrate, fabric lamination, and waterjet edging. Achieving this edging requires precise fabric cutting dimensions and a stable support structure. Current waterjet cutting fixtures use steel plates to support the product during waterjet cutting. However, the support surface cannot perfectly conform to the shape of various products, limiting cutting to a single product and impacting the fixture's accuracy, stability, and versatility. Furthermore, the steel plate support prevents drainage, posing a risk of backflow. Utility Model Content

[0004] The purpose of this utility model is to provide a support mechanism and a roof waterjet cutting fixture, which has high precision, stable support and strong versatility.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On one hand, this embodiment provides a support mechanism for supporting the front and rear edges of the canopy fabric, including a connecting component and multiple support components. The support components include fixedly connected support members and support profiles. The multiple support components have support profiles of different shapes. The multiple support components can be selectively connected to the mounting plate of the canopy waterjet cutting fixture. The support members of the support components can be detachably connected to the mounting plate through the connecting component. The support profiles of the support components connected to the mounting plate are used to support the canopy and can fit against the profiles of the canopy.

[0007] Preferably, the connecting assembly includes a positioning square tube, a linear bearing, a guide shaft, and a fixed seat. The support member is a support rod, with one end of the support rod away from the support profile fixedly connected to the positioning square tube. The linear bearing is fixedly connected to the positioning square tube. The fixed seat is used for detachable connection to the mounting plate. The guide shaft is fixedly connected to the fixed seat and can be inserted into or pulled out of the inner ring of the linear bearing.

[0008] Preferably, each support component includes two support rods, which are connected in parallel and spaced apart to the support surface, and each support rod is fixedly connected to a positioning square tube.

[0009] Preferably, the connecting assembly further includes a connecting rod, which is fixedly connected between the two positioning square tubes and is arranged perpendicular to the support rod.

[0010] Preferably, the connecting assembly includes at least two connecting rods, which are arranged in parallel and are fixedly connected between the two positioning square tubes.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] On the one hand, please refer to Figures 1 to 4 This embodiment provides a support mechanism 1 for supporting the front and rear edges of the canopy fabric. It includes a connecting component 11 and multiple support components 12. Each support component 12 includes a fixedly connected support member 121 and a support profile 122. The multiple support components 12 have support profiles 122 of different shapes. The multiple support components 12 can be selectively connected to the mounting plate of the canopy waterjet cutting fixture. The support member 121 of the support component 12 can be detachably connected to the mounting plate through the connecting component 11. The support profile 122 of the support component 12 connected to the mounting plate is used to support the canopy and can fit against the profile of the canopy. The support mechanism 1, by replacing the support component 12, can meet the needs of quickly switching roof supports for different vehicle models, reducing the number and cost of special fixtures and offering strong versatility. Simultaneously, the support surface 122 conforms to the shape, eliminating support gaps in the support mechanism 1 and ensuring a perfect match between the support surface 122 and the roof's curved surface. This prevents fabric shaking or deformation due to insufficient support during waterjet cutting, improving the quality of the cut edges. The connecting component 11 allows the support component 12 to be detachably connected to the mounting plate, enabling modular replacement of the support component 12 and improving assembly efficiency. Specifically, the support surface 122 is composed of two conformal stainless steel round bars.

[0030] Further, please refer to Figure 2 and Figure 3The connecting assembly 11 includes a positioning square tube 111, a linear bearing 112, a guide shaft 113, and a fixing seat 114. The support member 121 is a support rod, with one end of the support rod away from the support profile 122 fixedly connected to the positioning square tube 111. The linear bearing 112 is fixedly connected to the positioning square tube 111. The fixing seat 114 is used for detachable connection to the mounting plate. The guide shaft 113 is fixedly connected to the fixing seat 114 and can be inserted into or removed from the inner ring of the linear bearing 112. Specifically, the support rod and the positioning square tube 111 are welded together to ensure reliable connection. The support rod, positioning square tube 111, and linear bearing 112 can be quickly inserted and removed along the guide shaft 113 as a whole. The fixing seat 114 is detachably connected to the mounting plate, making the position of the support mechanism 1 adjustable to accommodate different sizes of canopy fabric 4. This allows for quick replacement of the support assembly 12 and improves the versatility of the support mechanism 1. Specifically, the linear bearing 112 is provided with a round flange structure, which facilitates connection with the fixed seat 114.

[0031] Optionally, each support component 12 includes two support rods, which are connected in parallel and spaced apart to the support surface 122. Each support rod is fixedly connected to a positioning square tube 111. By setting two support rods, the support strength of the support component 12 is increased, and the positioning by the dual guide shafts 113 avoids the torsion of the support surface 122 that may be caused by single-point insertion and removal, thus ensuring positioning accuracy.

[0032] Optionally, the connecting assembly 11 further includes a connecting rod 115, which is fixedly connected between the two positioning square tubes 111 and is perpendicular to the support rod. This arrangement further enhances the structural strength and stability of the support mechanism 1, prevents deformation of the support mechanism 1 due to insertion and removal, and improves its service life.

[0033] Optionally, the connecting assembly 11 includes at least two connecting rods 115, which are arranged in parallel and fixedly connected between the two positioning square tubes 111. This further enhances the stability of the support mechanism 1. Specifically, the connecting rods 115 are stainless steel round bars with a diameter of 10mm, and are welded to the positioning square tubes 111.

[0034] Furthermore, the support mechanism 1 is made of stainless steel to ensure that it is not prone to rusting, deformation or damage under waterjet cutting conditions.

[0035] On the other hand, please refer to Figure 1 and Figure 4A waterjet cutting fixture for roof linings is provided, comprising: a base 2, fasteners, multiple mounting plates, and the aforementioned support mechanism 1. The multiple mounting plates extend along a first direction and are fixedly connected to the base 2 in parallel intervals along a second direction. The connecting component 11 of each support mechanism 1 can be selectively screwed onto two adjacent mounting plates. The first and second directions are perpendicular. Specifically, the fasteners are bolts; in other embodiments, the fasteners can also be screws, connecting pins, etc. The base 2 has a rectangular frame structure, which makes the roof waterjet cutting fixture lightweight and facilitates drainage. When waterjet cutting is required, the support mechanism 1 corresponding to the support surface 122 is selected according to the vehicle model; two linear bearings 112 are simultaneously aligned with the guide shafts 113 on two adjacent mounting plates, inserted to the bottom in one go, and locked; after the support mechanism 1 is installed, the roof fabric 4 to be cut is placed, and the support surface 122 provides conformal support for the roof fabric 4, and the waterjet cuts according to the program; when a different vehicle model is needed, only the entire support component 12 needs to be removed and replaced with another set. The quick insertion and removal of the support mechanism 1 improves the changeover efficiency of the production line.

[0036] Specifically, the waterjet cutting fixture for the canopy includes four support mechanisms 1. Two of the four support mechanisms 1 are used to support the front edge of the canopy fabric 4, and the other two support mechanisms 1 are used to support the rear edge of the canopy fabric 4. By supporting the front edge and the rear edge of the canopy fabric 4, full canopy support is achieved with fewer support modules, ensuring support stability.

[0037] Alternatively, please refer to Figure 1 Two support mechanisms 1 for supporting the leading edge of the canopy fabric 4 are spaced apart along the second direction and located on a first plane perpendicular to the base 2 (e.g., Figure 1 On the surface shown in S1, two support mechanisms 1 for supporting the rear edge of the canopy fabric 4 are spaced apart along the second direction and located on a second plane perpendicular to the base 2 (as shown in S1). Figure 1 As shown in S2, the first plane and the second plane are arranged parallel to each other along the first direction. The spaced arrangement of two adjacent support mechanisms 1 forms a drainage channel, allowing water or waste generated during water cutting to be discharged without splashing upwards onto the canopy fabric 4, reducing the risk of backflow and ensuring the quality and precision of the water cutting.

[0038] Furthermore, the distance between the support surfaces 122 of the two support mechanisms 1 used to support the front edge of the canopy fabric 4 is not less than 10 mm; and / or, the distance between the support surfaces 122 of the two support mechanisms 1 used to support the rear edge of the canopy fabric 4 is not less than 10 mm. Specifically, the distance between the support surfaces 122 of the two support mechanisms 1 used to support the front edge of the canopy fabric 4; and / or, the distance between the support surfaces 122 of the two support mechanisms 1 used to support the rear edge of the canopy fabric 4 is the cutting edge of the water jet of the water jet cutting device, preferably, the width of the cutting edge is 10 mm.

[0039] Optionally, scale lines are spaced apart on multiple mounting plates. Workers can adjust the positions of the multiple support mechanisms 1 and the distance between them according to the scale lines, facilitating the assembly of the ceiling waterjet cutting fixture and improving positioning accuracy.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
