[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] After automotive interior parts are pressed and molded, the scraps need to be cut off using a water jet cutting fixture. In related technologies, the water jet cutting fixture includes a fixture base frame, the fixture surface of which has the same shape and size as the bottom surface of the automotive interior parts, serving as a support surface to hold the automotive interior parts products.

[0004] However, most waterjet cutting fixtures for automotive interior parts are currently made of full-surface casting or fiberglass, with ZL104 aluminum alloy being a common material. These fixtures are not only large and heavy, resulting in high manufacturing costs, but also have long production cycles, which increases production costs. Utility Model Content

[0005] The purpose of this utility model is to provide a waterjet cutting fixture for automotive interior parts, which improves the efficiency of fixture manufacturing and reduces production costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A waterjet cutting fixture for automotive interior parts includes a fixture body and a fixture base frame. The fixture body includes multiple support components for supporting the interior parts to be cut. Each support component includes a lower support plate and an upper support plate.

[0030] 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.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] like Figure 1-4 As shown, an embodiment of this utility model provides a waterjet cutting fixture for automotive interior parts, including a fixture base frame 4 and a fixture body 3. The fixture body 3 includes multiple support components 5, which are used to support the interior parts to be cut. Each support component 5 includes a lower support plate 52 and an upper support plate 51. The multiple lower support plates 52 are spaced apart along a first direction and fixed to the fixture base frame 4, while the multiple upper support plates 51 are spaced apart along a second direction. The upper support plates 51 and the lower support plates 52 intersect and are fixedly connected. The first and second directions are perpendicular to each other. Specifically, the fixture base frame 4 is rectangular.

[0035] The interior trim piece to be cut is placed on the support assembly 5, which supports the piece. The effective surface of the trim piece is aligned with the support assembly 5, and then the excess material is removed using high-pressure water jet cutting technology. By forming a strip-shaped support structure with multiple lower support plates 52 and multiple upper support plates 51, the traditional integral casting or full-form fiberglass surface is decomposed into independent strip-shaped support plate units. The support structure is formed by standardized module splicing, eliminating the need for complex mold casting or integral molding processes, shortening the production cycle, improving fixture manufacturing efficiency, reducing material usage, and lowering production costs.

[0036] Optionally, the upper support plate 51 and the lower support plate 52 are made of stainless steel plates with a thickness of 3mm.

[0037] Furthermore, such as Figure 3 As shown, the lower support plate 52 has multiple upper notches, and the upper support plate 51 has multiple lower notches. The multiple lower notches and the multiple upper notches are arranged in a one-to-one correspondence and are inserted into each other.

[0038] The upper notch of the lower support plate 52 is inserted into the lower notch of the upper support plate 51 one-to-one. After alignment, manual welding is performed. The interlocking structure formed by the notch insertion increases the contact area between the upper support plate 51 and the lower support plate 52, improving stability and effectively reducing structural deformation during use. If a single support plate is partially damaged, the detachable feature of the notch insertion allows for individual replacement of the damaged part without the need to replace the entire fixture, achieving low-cost maintenance.

[0039] Furthermore, the lower support plate 52 and / or the upper support plate 51 are provided with serial number identifiers 53.

[0040] Since each fixture has dozens of fixture support plates, and the number of support plates is large and difficult to distinguish, in order to facilitate assembly and welding, each fixture support plate is marked with a serial number 53, and the serial numbers 53 are arranged in ascending order.

[0041] Furthermore, the waterjet cutting fixture for automotive interior parts also includes a crash barrier 6, which has a receiving space. Multiple support components 5 are disposed within the receiving space, and a lower support plate 52 and an upper support plate 51 are respectively connected to the inner walls of the crash barrier 6 in a first direction and a second direction. Specifically, the crash barrier 6 is a rectangular frame.

[0042] The anti-collision component 6 surrounds the support component 5, and the anti-collision component 6 protects the support component 5. During the handling or debugging of the fixture, the anti-collision component 6 can buffer external collisions, reduce the risk of damage to the support component 5, and extend the service life of the fixture.

[0043] The anti-collision component 6 is connected to the lower support plate 52 and the upper support plate 51 through the inner walls of the first and second directions respectively, forming a three-dimensional limiting structure. This structure can limit the displacement of the support component 5 during the cutting process, avoid surface deviation caused by the impact of high-pressure water flow, and thus improve the cutting accuracy.

[0044] Furthermore, such as Figure 4 As shown, the waterjet cutting fixture for automotive interior parts also includes a positioning component 7. The positioning component 7 includes a connecting plate 71 and a positioning post 72. The connecting plate 71 is fixedly connected to the lower support plate 52. The connecting plate 71 has a strip-shaped hole extending in the second direction. The positioning post 72 is fixed in the strip-shaped hole and is used to pass through the positioning hole of the interior part to be cut.

[0045] The strip-shaped hole extending along the second direction on the connecting plate 71 allows the positioning post 72 to be adjusted within a certain range, adapting to the needs of positioning holes at different positions on the interior trim to be cut. This eliminates the need for custom-designed positioning structures for each product, improving the versatility of the fixture. The positioning post 72 passes through the positioning hole on the interior trim to be cut, enabling rapid and precise positioning of the trim on the support component 5. This effectively fixes the trim, preventing cutting deviations caused by displacement of the trim during high-pressure water cutting, ensuring that the cut product meets design dimensional requirements, and improving product quality.

[0046] Furthermore, multiple positioning components 7 are provided, and multiple positioning posts 72 of the multiple positioning components 7 are used to pass through multiple positioning holes of the interior trim to be cut in a one-to-one correspondence.

[0047] like Figure 1 and Figure 2As shown, the interior trim to be cut includes Product 1 and Product 2. Product 1 and Product 2 are respectively provided with multiple positioning holes, which correspond one-to-one with multiple positioning posts 72. Multi-point limiting can improve the stability of the interior trim to be cut and effectively reduce the shaking or displacement of the interior trim to be cut during the cutting process.

[0048] Specifically, there are a total of 8 positioning holes on Product 1 and Product 2, located at the front and rear of the product respectively, with 2 holes on each side.

[0049] Understandably, products 1 and 2 are mounted on fixture body 3. In order to improve production efficiency, the waterjet chamber is equipped with two waterjet cutting heads on the left and right, which can waterjet cut the two products on the left and right at the same time. Thus, the arrangement of products 1 and 2 is consistent with the distribution of the waterjet cutting heads in the waterjet chamber.

[0050] Similarly, a positioning plate 9 is fixedly connected to the bottom frame 4 of the fixture, and the positioning plate 9 is provided with a positioning through hole.

[0051] The positioning plate 9 has a high-precision positioning through hole, and a positioning part adapted to the positioning through hole is set on the workbench of the waterjet chamber to ensure the positioning accuracy between the fixture body 3 and the fixture bottom frame 4.

[0052] Furthermore, the waterjet cutting fixture for automotive interior parts also includes a pad 8, which is located between the fixture base frame 4 and the fixture body 3. Specifically, the pad 8 is a stainless steel hollow square tube.

[0053] Because the working arm of the waterjet cutting room robot has a specific range of length, the height from the worktable to the upper surface of the fixture body 3 has specific requirements. By setting a pad 8 between the fixture base frame 4 and the fixture body 3, the fixture body 3 can be appropriately raised to meet the height requirements of the worktable. Specifically, the height from the worktable to the upper surface of the fixture body 3 shall not be less than 200mm.

[0054] Furthermore, the height of the pad 8 is 40mm-100mm. The size of the stainless steel hollow square tube is set according to actual needs. By replacing the stainless steel hollow square tube with different specifications and sizes, it can adapt to the height requirements of the workbench for different interior parts to be cut.

[0055] Furthermore, the jig base frame 4 is fixedly connected with multiple lifting rings 10, which are used to lift the jig base frame 4.

[0056] When it is necessary to move or adjust the jig, the jig can be lifted to the target area using the lifting hook and lifting ring 10, which is convenient to operate. For example... Figure 2 As shown, a lifting ring 10 is provided at each of the four corners of the jig's bottom frame 4, which can improve the stability of the jig during lifting.

[0057] Optionally, the lifting ring 10 is made of stainless steel and has a diameter of 40mm.

[0058] 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.
