Description

Technical Field

[0001] This invention relates to the field of yarn weaving tools, and in particular to an adjustable contour guide ring mechanism. Background Technology

[0002] 3D braiding is a technique that interweaves multiple sets of yarns under the guidance of a yarn carrier, attaching them to the surface of a component to form a fabric with a complex spatial structure. This technique enables the continuous arrangement of fibers in three-dimensional space, thereby enhancing the integrity and anti-delamination properties of the material. 3D braiding is primarily used in the manufacture of high-performance composite materials, such as key components in aerospace, wind power, and automotive industries.

[0003] As a key component of 3D weaving equipment, the guide ring primarily guides the direction of yarn movement. It accurately converges yarns from different directions into specific weaving areas, ensuring the yarns maintain the correct position and angle during interlacing. By rationally setting the position and shape of the guide ring, the convergence area of ​​the yarn can be effectively controlled, allowing the yarn to be evenly distributed on the component surface, thus forming a regular and stable weaving structure. Furthermore, the guide ring can also adjust the yarn tension to a certain extent, reducing friction and wear during yarn movement, increasing yarn lifespan, and ensuring the smooth progress of the weaving process.

[0004] Currently, 3D weaving equipment typically uses fixed guide rings with a fixed shape. When dealing with irregularly shaped components or components that require eccentric weaving, the fixed guide rings, due to their fixed shape, cannot be adjusted during the weaving process. This will affect the weaving angle of such components, resulting in uneven distribution of yarn on the surface of the component, affecting coverage and appearance quality, and in more serious cases, directly reducing the mechanical properties of the final product.

Multiple contouring adjustment modules 4 are arranged at intervals around the circumferential adjustment mounting ring 2.

[0023] The contouring adjustment module 4 includes a contouring adjustment drive component and a contouring adjustment structure component. The contouring adjustment drive component and the contouring adjustment structure component are connected by a drive. Each of the contouring adjustment structure components forms a guide ring space. The contouring adjustment drive component drives the contouring adjustment structure component to move in order to adjust the shape and size of the guide ring space.

[0026] In this embodiment, please refer to Figures 3-4The circumferential adjustment transmission assembly includes a circumferential adjustment gear 6 and a circumferential adjustment gear ring 7.

The circumferential adjustment guide wheels 9 and the circumferential adjustment annular guide rail 8 are in rolling engagement. The circumferential adjustment guide rail is annular in shape. Optionally, guide rail sections are provided on both the inner and outer sides of the circumferential adjustment guide rail. Multiple circumferential adjustment guide wheels 9 are distributed on the inner and outer sides of the circumferential adjustment guide rail and are in rolling engagement with the circumferential adjustment guide rail, forming a clamping rolling form, which makes the rotational engagement more stable.

[0028] In this embodiment, please refer to Figures 1-4 The outer side of the circumferential adjusting gear ring 7 is provided with multiple fixed bracket assemblies 10. Each fixed bracket assembly 10 includes a fixed bracket rod 11 and a fixed bracket plate 12. One end of the fixed bracket rod 11 is connected to the circumferential adjusting gear ring 7, and the other end of the fixed bracket rod 11 is connected to the fixed bracket plate 12. The contour guide ring mechanism of the present invention is installed and applied on a braiding machine. Therefore, the fixed bracket assembly 10 facilitates the fixed installation of the mechanism components of the present invention on the corresponding braiding machine. The entire mechanism is connected to the braiding machine through the fixed bracket assembly 10. One end of the fixed bracket rod 11 in the fixed bracket assembly 10 is connected to the outer side of the circumferential adjusting gear ring 7, wherein the outer side of the circumferential adjusting gear ring 7 is the side of the circumferential adjusting gear ring 7 away from the circumferential adjusting annular guide rail 8.

The fixed bracket plate 12 is installed and connected to the braiding machine.

[0029] In this embodiment, please refer to Figures 2-3Each of the contouring adjustment modules 4 is evenly spaced on the circumferential adjustment mounting ring 2, and each of the contouring adjustment modules 4 equally divides the circumference of the circumferential adjustment mounting ring 2. The evenly spaced arrangement of the contouring adjustment modules 4 on the circumferential adjustment mounting ring 2 makes the guide ring space formed during the adjustment process more uniform in all places, resulting in a better contouring effect.

[0030] In this embodiment, please refer to Figure 1 and Figure 5 The contouring adjustment drive assembly includes a contouring adjustment servo motor 13, a contouring adjustment transmission gear set, and a contouring adjustment moving slide block; the contouring adjustment transmission gear set includes a contouring adjustment transmission rack 14 and a contouring adjustment transmission gear 15, and the contouring adjustment moving slide block includes a contouring adjustment slider 16 and a contouring adjustment slide rail 17. The contouring adjustment servo motor 13 is mounted on the circumferential adjustment mounting ring 2, the contouring adjustment transmission gear 15 is mounted on the output end of the contouring adjustment servo motor 13, the contouring adjustment transmission rack 14 and the contouring adjustment transmission gear 15 are engaged, the contouring adjustment slider 16 is fixed on the circumferential adjustment mounting ring 2, the contouring adjustment slider 16 is slidably mounted on the contouring adjustment slide rail 17, and the contouring adjustment transmission rack 14 and the contouring adjustment slider 16 are connected. The contouring adjustment slide rail 17 extends along its length towards the center of the circumferential adjustment mounting ring 2. Both ends of the contouring adjustment slide rail 17 extend along its guiding direction. The contouring adjustment transmission rack 14 and the contouring adjustment transmission gear 15 in the contouring adjustment transmission gear assembly mesh with each other to transmit power. The sliding engagement between the contouring adjustment slider 16 in the contouring adjustment moving slide assembly and the contouring adjustment slide rail 17 provides power guidance, thereby achieving position adjustment of the contouring adjustment structural components. Optionally, the six contouring adjustment drive components can be configured to be identical.

[0031] In this embodiment, please refer to Figures 5-7 The contouring adjustment structure assembly includes a contouring adjustment connecting rod 21 and a contouring adjustment composite component. One end of the contouring adjustment connecting rod 21 is connected to the contouring adjustment slider 16, and the other end of the contouring adjustment connecting rod 21 is connected to the contouring adjustment composite component. To prevent the contouring adjustment drive assembly from causing the contouring composite component to come into contact too closely at certain extreme positions during adjustment, the contouring adjustment structure assembly can be set at different heights (either some of the contouring adjustment structure components have different heights, or all of the contouring adjustment structure components have different heights), which can improve safety to a certain extent.

[0032] In this embodiment, please refer to Figures 5-11The inner and outer sides of the contouring adjustment assembly are respectively the contouring connection surface and the contouring assembly surface; the contouring connection surface is connected to the contouring adjustment connecting rod 21, and the contouring assembly surface faces the guide ring space inside the circumferential adjustment mounting ring 2; The contouring surfaces of the plurality of contouring adjustment structure components can form a guide ring space, and the guide ring space is a closed space; The cross-section of the contoured composite surface can be a straight line, a semicircle, or a semi-arc, and the centerline of the contoured composite surface can be an inwardly concave arc, an outwardly convex arc, or a straight line. When the cross section of the contouring composite surface and the cross section of the contouring adjustment connecting rod 21 are semicircles with the same radius, the contouring adjustment composite can be a concave arc-shaped round tube 19, a convex arc-shaped round tube 18, or a straight round tube 20. The six contouring adjustment components can be partially identical, that is, they can be identical in pairs and divided into three groups. The three groups of contouring adjustment components are the concave arc-shaped round tube 19, the convex arc-shaped round tube 18, and the straight round tube 20, and the two adjacent contouring adjustment components are not the same. The six contour-adjustable composite parts can all be different.

[0033] This invention, by setting three different outer surfaces, enables the simulation of guide ring spaces that are roughly circular, elliptical, triangular, rectangular, or other irregular shapes formed during the contouring synthesis process.

[0034] In this embodiment, the control module includes a motion controller and multiple servo drivers. The motion controller and the servo drivers are electrically connected. The number of servo drivers is the same as the number of contouring adjustment servo motors 13. Each servo driver controls its corresponding contouring adjustment servo motor 13. The control module utilizes the motion controller to drive the corresponding contouring adjustment servo motor 13 via the servo drivers, thereby automatically controlling and adjusting the position of the contouring composite part according to specific needs. This achieves adjustment of the simulated contouring guide ring, resulting in higher automation, reduced labor intensity for workers, and improved production efficiency. Optionally, the mainstream EtherCAT bus communication method can also be used to control the adjustment servo motors, achieving synchronous, real-time, and high-precision characteristics. This also eliminates the labor costs associated with complex wiring circuits and saves significant processing space. EtherCAT bus communication is existing technology and will not be elaborated upon here.

Each contouring adjustment structural component within the module surrounds and forms a simulated guide ring space through contouring. The contouring adjustment drive component within each module can move the contouring adjustment structural components, thereby changing the shape and size of the simulated guide ring space. Simultaneously, the circumferential adjustment rotation drive component, in conjunction with the module, rotates the circumferential adjustment mounting ring, changing the circumferential position of each contouring adjustment module and further adjusting the guide ring space. Therefore, this invention can adjust the shape of the simulated contouring guide ring in a timely manner during yarn weaving, adapting to different weaving conditions and flexibly meeting the weaving structure requirements of specific products, thus improving product quality and production efficiency. Furthermore, this invention uses a contour-simulated guide ring structure, eliminating the need to install and disassemble physical guide rings, reducing workload and improving installation and configuration efficiency. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.
