Description

Technical Field

[0001] This utility model relates to the field of composite material production tooling technology, specifically to a layup tooling. Background Technology

[0002] Many composite material products are closed cylindrical structures, including both round and flat cylinders. These products typically have a core mold that conforms to the shape of the cylinder's inner wall. There are two ways to lay up these core molds: placing them with their axis perpendicular to the worktable. This method is only suitable for core molds with a small length-to-diameter ratio. Core molds with a large length-to-diameter ratio have a high center of gravity; for example, core molds with a length-to-diameter ratio greater than 3 are prone to tipping over during construction, posing a danger. Placing the core mold's axis parallel to the worktable is suitable for core molds with a large length-to-diameter ratio and a low center of gravity. However, this method is inconvenient for non-cylindrical products during layup and flipping, while cylindrical products are easy to flip but prone to rolling off the worktable, causing a hazard.

[0003] In summary, there is an urgent need for a layup tooling to solve, or at least partially solve, the problems existing in the prior art. Utility Model Content

[0008] Preferably, the support assembly further includes a limiting element, which includes a chain and a limiting screw. The limiting screw is detachably connected to the support block, and the chain includes a first end for connecting with the limiting screw and a second end for connecting with the core mold.

[0009] Preferably, the bracket is slidable and positioned along the length of the base frame.

[0010] Furthermore, a slide rail is provided on the base frame, and a slide groove is provided at the bottom of the bracket.

Detailed Implementation

[0018] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] Example: See Figures 1-9This embodiment provides a layup fixture, including a base frame 1 and two brackets 2, which are arranged opposite to each other above the base frame 1; it also includes two support components 3 for matching with the core mold, which are fixedly connected to the top of the two brackets 2 respectively; an operating space 4 is formed between the two brackets 2.

[0021] It should be noted that the core molds include circular core molds 8, flat core molds 7, and some other irregularly shaped core molds. For core molds with a large length-to-diameter ratio, it is not possible to lay them up vertically. Therefore, the conventional layup method for such core molds is to place them on a flat worktable. When laying up on a flat worktable, the bottom of the core mold also needs to be laid up, and since the bottom of the core mold is supported on the platform, it is necessary to flip the core mold back and forth. This is inconvenient and affects the efficiency of the layup.

[0022] Research revealed that by supporting the core mold from both ends, leaving the bottom of the core mold open, layering can be performed on the core mold without flipping it. Through this structural design, two supporting components 3 support both ends of the core mold, suspending the areas where layering is required. For areas above the core mold, layering can be performed directly; for areas at the bottom, layering can be performed from bottom to top through the operating space 4. This allows for layering of the core mold without flipping it, reducing labor intensity and improving operational efficiency.

[0023] The most commonly used layup material is a woven carbon fiber fabric laid on a core mold, with resin brushed onto the carbon fiber fabric to completely impregnate it. Multiple layers of carbon fiber can be laid in sequence, with a layer of resin brushed on each layer of carbon fiber.

[0024] As one of the preferred embodiments of this application, the support component 3 includes a support block 31, and a U-shaped groove 311 is provided on the support block 31 along the length direction of the base frame 1. Multiple U-shaped grooves 311 are provided, and the multiple U-shaped grooves 311 are arranged at intervals along the width direction of the base frame 1.

[0025] It should be noted that for both flat and irregularly shaped core molds 7, two handles 71 are provided at each end of the core mold. Both handles 71 are arranged along the axis of the core mold, and the distance between the two handles 71 is set to be equal to the distance between two corresponding U-shaped grooves 311. Furthermore, the diameter of the handles 71 is less than or equal to the width of the U-shaped groove 311, allowing the two handles 71 to be inserted into the U-shaped groove 311 from top to bottom. When installing the flat or irregularly shaped core mold 7 onto the support assembly 3, the flat core mold 7 is lifted upwards by holding the handles 71 from both ends, allowing the handles 71 to be inserted into the U-shaped groove 311 from top to bottom. The flat core mold 7 is supported by the U-shaped groove 311 and the handles 71. It should be noted that the center of gravity of the flat core mold is located between the two handles 71 to prevent the flat core mold 7 from rotating due to instability after installation.

[0026] Specifically, in this embodiment, each support block 31 is provided with two U-shaped grooves 311 to correspond to the two handles 71 on the flat core mold 7. Of course, in some other embodiments, three or more U-shaped grooves 311 may be provided. It is worth noting that the length of the handle 71 is longer than the length of the U-shaped groove 311, so that after the flat core mold 7 is installed, the handle 71 can extend from the end of the U-shaped groove 311. This extended part is convenient for the operator to grip, so as to facilitate the movement or handling of the flat core mold 7.

[0027] After the above improvements, the device can now accommodate non-rotating flat core molds 7 and irregularly shaped core molds for layup. However, for circular core molds 8, if they can be rotated and flipped, layup operations can be performed more conveniently. Based on this, the following further improvements are made.

[0028] In another preferred embodiment of this application, the supporting component 3 further includes two rollers 32. A clearance groove 312 is provided on the supporting block 31 along the width direction of the base frame 1. Both rollers 32 are rotatably arranged in the clearance groove 312, and the rolling shafts of the rollers 32 are embedded in U-shaped grooves 311. The two rollers 32 are spaced apart along the width direction of the base frame 1. The axes of the rollers 32 are arranged along the length direction of the base frame 1. That is, the U-shaped groove 311 serves both as a limiting handle 71 and as a means of installing and positioning the rollers 32.

[0029] It should be noted that, for the circular mandrel 8, two circular end plates 81 are coaxially mounted at both ends of the circular mandrel 8, supporting the circular end plates between two rollers 32. This structural arrangement allows the circular mandrel 8 to roll around its own axis, facilitating rotation and flipping. This allows the surface to be laid to the top during layering, making layering easier and improving the quality of the layering process. Furthermore, laying layers from above allows for direct observation of defects, reducing the production of defective products. When the circular mandrel 8 needs to be rotated, the operator manually rotates the end plates to rotate the mandrel 8, making the operation relatively convenient.

[0030] Preferably, the support assembly 3 further includes a stop block 33 and a fastener 34. The stop block 33 is detachably connected to the support block 31 by the fastener 34, and the stop block 33 is arranged at the end of the support block 31 away from the other support block 31. The stop block 33 protrudes from the top of the support block 31 along the height direction of the support block 31. Specifically, the fastener 34 is a screw, and the stop block 33 has a threaded hole and a through hole. The screw passes through the through hole on the stop block 33 and is threadedly connected to the threaded hole on the support block 31.

[0031] By setting a stop 33 on the support block 31, the circular core mold 8 is axially limited to prevent the circular core mold 8 from moving along its own axis during rotation, which would cause the circular core mold 8 to fall off the support assembly 3 and be damaged.

[0032] Preferably, the support assembly 3 further includes a limiting member 35, which includes a chain 351 and a limiting screw 352. The limiting screw 352 is detachably connected to the support block 31. The chain 351 includes a first end for connecting with the limiting screw 352 and a second end for connecting with the core mold.

[0033] It should be noted that the circular core mold 8 may pass over the roller 32 during rotation, which would cause it to fall off the support assembly 3. Therefore, the circular core mold 8 needs to be limited along the width of the base frame 1 to ensure that it remains between the two rollers 32 during operation. To achieve this, a limiting rod 82 is fixedly connected to the end of the circular end plate 81 furthest from the core mold, and the limiting rod 82 is coaxially arranged with the circular end plate 81.

[0034] Specifically, two limit screws 352 are arranged, and two threaded holes are arranged on the support block 31 corresponding to the limit screws 352. The two threaded holes are located on both sides of the stop block 33. The first end of the chain 351 is two free ends, and the second end of the chain 351 is the middle end of the chain 351. The two free ends of the chain 351 are provided with rings, which are threaded through the limit screws 352. The middle end of the chain 351 is wrapped around the limit rod 82. The chain 351 limits the limit rod 82, thereby limiting the circular end plate 81 and the circular core mold 8, preventing the circular core mold from falling off the support assembly 3 after passing the roller 32.

[0035] Preferably, the bracket 2 is slidable and positioned along the length of the base frame 1 to accommodate core molds of different lengths. Specifically, a slide rail 11 is provided on the base frame 1, and a slide groove is provided at the bottom of the bracket 2. The slide rail 11 and the slide groove are slidably engaged, and the bracket 2 is slidably connected to the slide rail 11. A first positioning hole 12 is provided on the slide rail 11, which is arranged along the height direction. Multiple first positioning holes 12 are provided and spaced apart along the length of the slide rail 11. A second positioning hole 21 is provided on the bracket 2, which is arranged through the bracket 2 along the height direction. The device also includes a positioning pin 5, which is arranged along the height direction, passing sequentially through the second positioning hole 21 and the first positioning hole 12 corresponding to the second positioning hole 21.

[0036] It can be seen that when it is necessary to adjust the distance between the two brackets 2, the bracket 2 is unlocked by pulling the positioning pin 5 upward. The bracket 2 can slide back and forth along the length of the base frame 1. The bracket 2 is adjusted to the required position and the second positioning hole 21 on the bracket 2 is aligned with the corresponding first positioning hole 12 on the slide rail 11. Then, the positioning pin 5 is inserted from top to bottom into the second positioning hole 21 and the first positioning hole 12 corresponding to the second positioning hole 21. At this time, the bracket 2 is relocked, and the position adjustment of the bracket 2 is completed.

[0037] Furthermore, two slide rails 11 are arranged, and the first positioning holes 12 on each slide rail 11 are arranged at equal intervals; the second positioning holes 21 are arranged in two sets corresponding to the two slide rails 11, and each set of second positioning holes 21 includes three second positioning holes 21. The three second positioning holes 21 are arranged at non-equal intervals along the length direction of the base frame 1, and the distance between the two second positioning holes 21 at both ends of the three second positioning holes 21 is less than the distance between two adjacent first positioning holes 12 on the slide rail 11.

[0038] It should be noted that when there is only one second positioning hole 21 on the bracket 2 corresponding to the slide rail 11, the smallest unit of movement of the bracket 2 is the distance between two adjacent second positioning holes 21, and there is no way to make fine adjustments. Through the above structural design, the distance between two adjacent second positioning holes 21 is smaller than the distance between two adjacent first positioning holes 12, and the distance between the two second positioning holes 21 at both ends is also smaller than the distance between two adjacent first positioning holes 12. Fine adjustments can be achieved by inserting the positioning pin 5 into different second positioning holes 21.

[0039] Preferably, the system also includes support wheels 6, which are fixedly connected to the bottom of the base frame 1. Multiple support wheels 6 are provided, spaced apart at intervals on the bottom of the base frame 1. Specifically, six support wheels 6 are arranged: four at the four corners of the base frame 1 and the other two supporting the middle of the base frame 1. The support wheels 6 provide support for the base frame 1, facilitating its movement.

[0040] Preferably, the support wheel 6 is a swivel wheel with a brake, and the support wheel 6 is detachably connected to the bottom of the base frame 1 by screws. Of course, in some other embodiments, the support wheel 6 can also be fixedly connected to the base frame 1 by welding.

[0041] The support wheel 6 is a swivel wheel, which makes it easy to move the device in the required direction; the support wheel 6 is equipped with a brake to position the base frame 1 and prevent the device from moving uncontrollably during use; the detachable design allows the support wheel 6 to be removed and replaced in time when it is damaged, which is convenient for inspection and maintenance.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
