Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This application provides a curing and shaping fixture for a cylindrical carbon fiber preform, solving two problems associated with traditional shaping methods. Firstly, traditional fixtures suffer from poor clamping stability. During the curing process, the preform is easily displaced and deformed by external forces or its own weight, resulting in low dimensional accuracy and poor shape compliance, thus affecting product quality. Secondly, traditional fixtures have poor versatility; different models of preforms require different fixtures. Furthermore, the fixture's clamping components are poorly designed, failing to fit tightly against the cylindrical preform, resulting in uneven clamping force distribution and difficulty in meeting high-precision shaping requirements.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example 1: This embodiment of the present invention discloses a curing and shaping tooling for a cylindrical carbon fiber preform, according to the attached... Figure 1-5 As shown, it includes a base 1, a tooling bracket 2, a clamping platform 3, an arc-shaped clamping plate 4, and an adjustment unit 5;

[0035] Base 1 is used to support the tooling;

[0036] The tooling bracket 2 is set on the base 1 and is used to initially limit the cylindrical preform mold 6; the tooling bracket 2 enables the cylindrical preform mold 6 to quickly be placed within the set position range, laying the foundation for subsequent precise clamping operations and improving shaping efficiency.

[0037] The clamping table 3 is slidably connected above the tooling bracket 2; the clamping table 3 can be flexibly changed in position to facilitate quick clamping and limiting or releasing the cylindrical preform mold 6.

[0038] The arc-shaped clamping plate 4 is set on the clamping platform 3, and the cylindrical preform mold 6 is clamped between the two sets of arc-shaped clamping plates 4. The arc-shaped design of the arc-shaped clamping plate 4 can fit closely with the outer contour of the cylindrical preform mold 6, provide uniform clamping force, ensure the shape stability and quality of the preform during the hardening and shaping process, and provide lateral support for the preform.

[0039] Adjustment unit 5 is mounted on base 1 and used to adjust the position of clamping platform 3. Through the cooperation of guide rail 51, slider 52, motor 53, bidirectional screw 54, and transverse arm 55, adjustment unit 5 can precisely adjust the position of clamping platform 3, achieving accurate clamping and positioning of the cylindrical preform mold 6, thus improving shaping accuracy and quality.

[0040] Adjustment unit 5 includes:

[0041] The guide rail seat 51 is fixedly connected to the base 1; the guide rail seat 51 provides a stable sliding track for the slider 52, ensuring that the slider 52 can move smoothly in a predetermined direction.

[0042] The slider 52 is slidably connected to the guide rail seat 51. The slider 52 is threaded and driven by the bidirectional screw 54. It can slide along the guide rail seat 51 under the drive of the motor 53, thereby driving the transverse arm 55 and the clamping table 3 to move, so as to achieve precise clamping and positioning of the cylindrical preform mold 6.

[0043] The motor 53 is fixedly connected to the guide rail seat 51; the rotation direction of the bidirectional screw 54 is controlled by the forward and reverse rotation of the motor 53, thereby realizing the left and right movement of the slider 52, which is easy to operate.

[0044] The bidirectional screw 54 is fixedly connected to the output end of the motor 53 and threadedly connected to the slider 52; the bidirectional screw 54 converts the rotational motion of the motor 53 into the linear motion of the slider 52, and has the advantages of high transmission accuracy, good stability and strong load-bearing capacity.

[0045] The horizontal arm 55 is fixedly connected to the slider 52 and is engaged with the clamping table 3. As an intermediate component connecting the slider 52 and the clamping table 3, the horizontal arm 55 transmits the movement of the slider 52 to the clamping table 3, thereby achieving precise control of the clamping table 3.

[0046] An installation tube 31 is fixedly connected to the clamping platform 3, and a positioning pin 551 is fixedly connected to the transverse arm 55. The positioning pin 551 is snapped into the installation tube 31. The snap-fit ​​connection between the positioning pin 551 and the installation tube 31 enables quick connection and positioning between the clamping platform 3 and the transverse arm 55. A locking pin 32 is threaded between the positioning pin 551 and the installation tube 31. The locking pin 32 further secures the positioning pin 551 to the installation tube 31, improving the efficiency of installation and disassembly, while also ensuring the reliability and stability of the connection. This ensures that the clamping platform 3 will not shift or loosen during clamping, avoiding any impact on the shaping effect. It also facilitates the replacement of various models of clamping platforms 3 and arc-shaped clamping plates 4 according to actual needs, thereby adapting to various models of cylindrical precast molds 6.

[0047] A limiting sleeve 21 for limiting the cylindrical preform mold 6 is fixedly connected to the tooling bracket 2. The limiting sleeve 21 realizes the initial and rapid limiting of the cylindrical preform mold 6.

[0048] A rubber pad 41 is fixedly connected to the arc-shaped clamping plate 4, and multiple sets of structural holes 42 for weight reduction are opened on the arc-shaped clamping plate 4. The rubber pad 41 can play a buffering and protective role when clamping the cylindrical preform mold 6, preventing the arc-shaped clamping plate 4 from directly contacting the surface of the preform and causing damage. At the same time, the rubber pad 41 has a certain degree of elasticity, which can increase the friction with the surface of the preform, making the clamping more secure and reliable, and avoiding deformation or displacement of the preform due to unstable clamping during the shaping process.

[0049] The operation steps for the hardening and shaping tooling of the cylindrical carbon fiber preform are as follows:

[0050] Place base 1 in a suitable working position and fix it in place.

[0051] The cylindrical preform mold 6 is placed on the tooling bracket 2 and engaged with the limiting sleeve 21.

[0052] Start the motor 53, which drives the bidirectional screw 54 to rotate, thereby causing the slider 52, which is threaded to it, to slide along the guide rail seat 51.

[0053] As the slider 52 slides, the horizontal arm 55 fixedly connected to it moves accordingly, thereby driving the clamping table 3, which is engaged with the horizontal arm 55, to move closer to the cylindrical preform mold 6.

[0054] When the arc-shaped clamping plate 4 on the clamping table 3 contacts the cylindrical preform mold 6, the rotation of the motor 53 is adjusted to further push the slider 52 to move until the arc-shaped clamping plate 4 clamps the cylindrical preform mold 6. At the same time, the rubber pad 41 is in close contact with the surface of the preform to ensure that the clamping is firm and reliable.

[0055] When it is necessary to replace the cylindrical precast mold 6, the connection between the positioning post 551 and the installation tube 31 can be unlocked by locking pin 32. Then, select a suitable model of arc-shaped clamping plate 4, replace the clamping table 3 and the arc-shaped clamping plate 4 and lock them to achieve the limitation of various models of cylindrical precast mold 6.

[0056] During the hardening and shaping process, maintain the clamping state to ensure the shape of the cylindrical preform mold 6 is stable. After it is completely hardened and shaped, reverse the operation of motor 53 to make slider 52 drive clamping table 3 to move away from cylindrical preform mold 6, release the clamping of the preform by arc-shaped clamping plate 4, and take out the shaped cylindrical carbon fiber preform.
