With the rapid improvement of overall capabilities in fiber raw materials and manufacturing equipment, they have been widely used in industries such as military, aerospace, wind power, high-speed trains, and new energy vehicles in recent years. In applications such as nuclear fuel and ultra-high-speed motors, the pursuit of higher rotor mechanical performance places increasingly higher demands on the mechanical properties, geometric accuracy, and initial defect control of composite material rotors during the molding process. Rotor curing is the final step in the molding of composite material rotors. Curing process parameters such as curing temperature, curing time, heating rate, and temperature field distribution directly affect the curing quality of composite material products; rotational accuracy and rotation time affect the uniformity of resin distribution and the distribution of rotor imbalance mass. Therefore, for the curing of various composite material products, including composite material rotors, optimization of curing equipment is necessary to meet requirements for economy and high precision.

[0023] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0024] For products with diverse types and small batches, traditional equipment and manufacturing methods inevitably require frequent modifications or even equipment replacements, resulting in excessive consumption and high costs. Therefore, the development of a high-precision rotary curing method and apparatus for composite material rotor molding is of great significance in the field of composite material manufacturing.

[0025] In a first aspect, to address the aforementioned problems, this application provides a composite material rotor rotation curing device. The device includes a heating chamber 1, with a temperature control and rotation control unit 3 located outside the heating chamber 1. Inside the heating chamber 1, there is a temperature regulating plate 16 and a multi-position array-type rotating support 2. The temperature regulating plate 16 is used to adjust the airflow and wind speed at different positions of the heating chamber 1. The top and bottom of the rotating support 2 are fixedly connected to the heating chamber 1. The front end of the rotating support 2 is provided with a connected drive component and an array-type front end mechanism 14. The drive component is located outside the front end of the rotating support 2, and the array-type front end mechanism 14 is located inside the front end of the rotating support 2. The rear end of the rotating support 2 is provided with an array-type rear end mechanism 15. The array-type front end mechanism 14 is used to drive and support the composite material rotor, and the array-type rear end mechanism 15 is used to adjust the support spacing and support accuracy of the composite material rotor. The drive component and the temperature regulating plate 16 are respectively connected to the temperature control and rotation control unit 3.

[0026] In this embodiment, a multi-station array-type rotating support 2 is designed, which can simultaneously cure and mold multiple rotors, significantly improving the manufacturing efficiency of composite material rotors. An adjustable support spacing mechanism ensures compatibility with multiple models and sizes of composite material rotors. An adjustable support precision mechanism ensures high-precision rotation, guaranteeing uniform resin flow during heating and achieving uniform rotor mass distribution control. A temperature uniformity adjustment unit controls the temperature uniformity of the heating chamber 1, enabling strict control of the composite material curing process and ensuring the composite material reaches the required degree of curing. It also effectively controls internal defects caused by temperature fluctuations during curing. This device offers advantages such as high efficiency, multiple degrees of freedom, good versatility, high precision, and strong scalability, making it particularly suitable for high-precision rotary heating and curing of complex-shaped composite material products.

[0027] In practical implementation, the temperature uniformity distribution inside the chamber is achieved through the configuration of the temperature regulating plate 16 and the temperature control unit, mainly including the hot air outlet and return air ducts and the hot air drive circulation system. A PID temperature acquisition and control system is developed to achieve programmed control of the curing temperature, curing time, and heating / cooling rates. A rotor rotation drive device with a flexible drive, an overall rigid frame, and rotating supports at both ends is designed to achieve high-precision rotor rotation heating, avoiding uneven quality caused by uneven resin distribution. Furthermore, by designing a motor operation status, measured temperature data monitoring, and data storage unit in the rotation drive structure 4, data traceability of the rotor curing process parameters is achieved.

[0028] Furthermore, the drive assembly includes a rotary drive structure 4, a bevel gear transmission unit 5, and a spur gear transmission unit 6. The array-layout front-end mechanism 14 includes a front-end rotary support mechanism 7. One end of the rotary drive structure 4 is connected to the temperature control and rotary control unit 3, and the other end of the rotary drive structure 4 is connected to the bevel gear transmission unit 5. The output end of the bevel gear transmission unit 5 is connected to the spur gear transmission unit 6, and the output end of the spur gear transmission unit 6 is connected to the front-end rotary support mechanism 7.

[0029] In specific implementation, refer to Figures 2 to 6 The rotary drive structure is the power input end of the entire transmission chain, and may include components such as a motor (e.g., a servo motor), a reducer, and a coupling, responsible for providing controllable rotational power and speed. The output shaft of the rotary drive structure directly drives the bevel gear transmission unit 5 to change the direction of power transmission. The bevel gear on the input shaft meshes with the bevel gear on the output shaft (vertical direction), converting the power from the horizontal direction to the vertical direction. The output shaft of the bevel gear transmission unit 5 drives the spur gear transmission unit 6. The core function of the spur gear transmission unit 6 is to distribute and synchronize power, ensuring that all driven parallel shafts rotate synchronously. Each output parallel shaft of the spur gear transmission unit 6 (corresponding to one workstation) is directly connected (or connected via a short shaft or coupling) to the front-end rotary support mechanism 7. The front-end rotary support mechanism 7 directly contacts and drives the composite material rotor to rotate.

[0030] Furthermore, the front end of the rotating bracket 2 is provided with multiple rows of support frames, and the front rotating support mechanism 7 is located on the support frames.

[0031] Furthermore, the rotary drive structure 4 is configured as a single-row drive or a multi-row drive.

[0032] In specific implementation, refer to Figure 3 The multi-station array-style rotating support 2 has 6 rows and 3 columns of workstations. The front end of the rotating support 2 is equipped with 6 rows of horizontal support frames to house the front rotating support mechanism 7. Correspondingly, the rotating drive structure 4 is configured with 3 columns of drive, with each rotating drive structure 4 corresponding to one column.

[0033] In one embodiment, reference is made to Figure 6 and Figure 7The array-type tail end mechanism 15 includes a tail adjustable bracket 8 and a length adjustment mechanism 12. The length adjustment mechanism 12 is set on the bottom and top of the rotating bracket 2 along the axial direction of the composite material rotor. The tail adjustable bracket 8 moves on the length adjustment mechanism 12 to adapt to composite material rotors of different lengths. The tail adjustable bracket 8 is used for adjusting the support spacing of the integral large stroke. The tail adjustable bracket 8 is set as a frame structure including multiple unit frames. Each unit frame is provided with a tail end adjustment bracket 10 corresponding to the front rotating support mechanism 7. Each tail end adjustment bracket 10 is provided with a precision adjustment component 9 and an axial limiting component 11. The axial limiting component 11 is used for adjusting the support spacing of the single station small stroke. The precision adjustment component 9 is used to adjust the radial runout and levelness of the composite material rotor.

[0034] In practice, the adjustable tail bracket 8 is fixed to the tail of the rotating bracket 2. The adjustable tail bracket 8 moves on the length adjustment mechanism 12 to adjust the axial distance between the front and rear support points. The adjustable tail bracket 8 mainly adjusts the overall large stroke to accommodate rotors of different lengths. The support spacing adjustment at each station is achieved through the tail-end adjusting bracket 10 and the axial limiting component 11. The limiting surface of the axial limiting component 11 faces the axial end face of the rotor tail to prevent axial movement of the rotor during rotation. Specifically, during rotor placement or adjustment, the axial limiting component 11 is adjusted, for example, by an adjustable stop (such as an adjusting screw with a locking nut) or a telescopic center sleeve, to maintain a small, preset gap (or slight contact pressure) between its limiting surface and the axial end face of the rotor tail. This prevents the rotor from moving along the axial direction due to the axial component of the driving force, thermal expansion, or vibration during rotation, ensuring the rotor is accurately positioned in the set position. The axial limiting component 11 does not provide primary support force; its main function is limiting.

[0035] The function of the precision adjustment device is to finely adjust the tail support point to ensure that the rotor, after being supported, achieves the required coaxiality (radial runout) and levelness (perpendicularity to the axis). For example, the precision adjustment device includes adjusting screws. By using the adjusting screws, the radial position of the tail support point (such as the bearing center) relative to the theoretical axis is finely adjusted to achieve radial runout adjustment, or the levelness of the plane where the tail support point is located or its perpendicularity to the rotor's theoretical axis is finely adjusted to achieve levelness adjustment. By setting up the precision adjustment device, residual deviations caused by manufacturing errors, installation errors, or length adjustments are eliminated, ensuring that the rotor axis is as straight as possible after being supported, and that the support surface is perpendicular to the axis (ensuring uniform mass distribution on the rotor end face and reducing dynamic imbalance), thereby achieving high-precision rotation, ensuring uniform resin distribution, and ultimately achieving rotor dynamic balance.

[0036] Furthermore, the length adjustment mechanism 12 is equipped with a fixing and locking mechanism 13, which is used to lock the position of the adjustable tail bracket 8. When the length adjustment mechanism 12 moves the adjustable tail bracket 8 to the target position, the fixing and locking mechanism 13 securely locks it onto the rotating bracket 2 to prevent displacement during the curing process.

[0037] In one embodiment, the structure of the composite material rotor includes a cylindrical structure and a variable diameter rotary structure.

[0038] In one embodiment, the heating method of the heating chamber 1 includes infrared heating and electric heating wire heating.

[0039] In one embodiment, the front rotating support mechanism 7 and / or the rear adjusting bracket 10 are made of lightweight, wear-resistant, and non-stick materials.

[0040] In one embodiment, the rotating support 2 adopts a 4×6 array layout, which can simultaneously rotate, heat and solidify 24 rotors.

[0041] Specifically, the working principle of the composite material rotor rotary curing device is as follows: Power start: The temperature control and rotation control unit 3 issues a command to start the motor in the rotation drive structure; Direction conversion: The rotational power generated by the motor is adjusted by the reducer and drives the input shaft of the bevel gear transmission unit 5. The bevel gear on the input shaft meshes with the bevel gear on the output shaft, turning the power 90 degrees and changing the horizontal drive at the bottom of the equipment to the vertical drive along the longitudinal direction of the support. Power distribution and synchronization: The output shaft of the bevel gear transmission unit 5 drives the main shaft of the spur gear transmission unit 6. The spur gear on the main shaft meshes with the driven gear. The meshing relationship of the gears ensures that: all driven shafts obtain the same speed and all driven shafts rotate in the same direction (all rotors rotate in the same direction). Rotor drive and support: The spur gear transmission unit 6 drives the front-end rotary support mechanism 7 of the corresponding workstation. The front-end rotary support mechanism 7 firmly clamps one end of the composite material rotor through its drive interface and transmits the rotational torque to the rotor. The other end of the rotor is supported by the tail-end adjustment bracket 10. The rotor is finely adjusted by the precision adjustment device (including radial runout and axial level). Combined with the spacing adjustment of the tail bracket, it is ensured that the rotor is supported with high precision and coaxially between the two support points.

[0042] Rotational curing process: Driven by the front-end rotational support mechanism 7, the rotor rotates at a constant speed within the heating chamber 1. Simultaneously, the temperature control system heats the chamber according to a set program (infrared or electric heating wire), and the hot air circulation system (via the temperature regulating plate 16, etc., see reference)... Figure 8To ensure temperature uniformity, the entire curing process (temperature, time, and rotation speed) is precisely controlled and recorded by the temperature control and rotation control unit 3.

[0043] The effects of rotation include: Uniform resin distribution: During the curing and heating stage (when the resin is in a viscous flow state), the combined action of centrifugal force and gravity promotes the uniform distribution of resin along the circumference, preventing imbalance caused by resin enrichment on one side. Reduce gravity-induced deformation: For large, thin-walled rotors, continuous rotation can counteract the sagging deformation caused by gravity. Uniform heating: Rotation allows all points on the rotor surface to be exposed to hot air more evenly, reducing temperature differences.

[0044] Secondly, embodiments of this application also provide a method for rotary curing of composite material rotors, employing the composite material rotor rotary curing apparatus as described in any embodiment of the first aspect, the method comprising: The temperature uniformity inside the heating chamber 1 is checked, and the temperature regulating plate 16 is adjusted to ensure that the temperature uniformity inside the heating chamber 1 meets the design requirements. Place the composite material rotor on the rotating support 2; Adjust the array-type tail end mechanism 15 to meet the structural dimensions and support accuracy requirements of the composite material rotor; Set the rotation and heating control program, start the temperature control and rotation control unit 3, and perform curing; After curing, cool to room temperature and remove the composite material rotor.

[0045] The following is a comparative example using a fixed support spacing structure, suitable for curing rotors of the same size. For workpieces with various structural dimensions, different support devices must be used. This results in higher costs, more complex structures, and compromised assembly and connection accuracy after replacement.

[0046] The following is an embodiment of this application, in which the axial spacing is adjustable. The support spacing of the rotating bracket 2 is adjusted according to the structural dimensions of the composite material rotor. The rotor is placed on the rotating bracket 2, and its installation accuracy is checked to meet the requirements. The rotation drive system and temperature control heating system are turned on, and the composite material rotor is rotated and heated to cure according to the set rotation speed and heating temperature. The process parameters such as rotation speed and duration, heating temperature and duration can be set according to actual needs. The specific workflow is as follows: (1) Check the temperature uniformity of the heating box 1. If necessary, adjust the opening and closing degree of the temperature regulating plate 16 to control the temperature uniformity inside the box to meet the design requirements; (2) Place the composite material rotor on the rotating bracket 2; (3) Adjust the tail adjustable bracket 8 and tail adjustment bracket at the end to meet the structural dimensions of the multi-model composite material rotor; (4) Adjust the precision adjustment component 9 of the composite material rotor to meet the design requirements; (5) Set the rotation and heating control program and start the temperature control and rotation control unit 3; (6) After curing is completed and automatically cooled to room temperature, the composite material rotor is taken out.

[0047] The embodiments provided by this invention feature a multi-station array-type rotary support 2, enabling simultaneous curing and molding of multiple rotors, significantly improving the manufacturing efficiency of composite material rotors. An adjustable support spacing mechanism ensures compatibility with various models and sizes of composite material rotors. An adjustable support precision mechanism ensures high-precision rotation, guaranteeing uniform resin flow during heating and achieving uniform rotor mass distribution control. A temperature uniformity adjustment unit controls the temperature uniformity of the heating chamber 1, enabling strict control of the composite material curing process and ensuring the required degree of curing, effectively controlling internal defects caused by temperature fluctuations during curing. This device offers advantages such as high efficiency, multiple degrees of freedom, good versatility, high precision, and strong scalability, making it particularly suitable for high-precision rotary heating and curing of complex-shaped composite material products.
