Description

Technical Field

[0001] The invention relates to the field of wind power generation tooling design, and in particular to a tooling parameterized rapid design platform and method for wind power generators. Background Art

[0002] In the existing wind turbine industry, tooling is mainly non-standard customization, and designers mainly use 3D and 2D software for drawing. Only parametric design is performed on the product design side, while the tooling design method is still the traditional 2D design method. Designers lack the method and experience accumulation of parametric rapid design on the tooling side, resulting in long tooling design time, low design efficiency, and the inability to reuse historical drawings. Under the existing technology, the key dimensions of some tooling are inevitably related to the R&D dimensions, but in the actual design process, the tooling drawings are not associated with the design drawings, which is easy to cause omissions in the design process, resulting in errors in the drawing of tooling dimensions. Therefore, there is a need for a parametric rapid design platform and method for tooling for wind turbines to improve tooling design efficiency and reduce design errors. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a tooling parametric rapid design platform for a wind turbine generator, including a tooling parametric design platform, wherein the tooling parametric design platform is established on UG software, and secondary development is performed based on the UG software to create an association relationship with a TC platform, wherein the tooling parametric design platform includes a tooling parametric design specification module and a tooling parametric design knowledge base, wherein the tooling parametric design specification module and the tooling parametric design knowledge base are stored in the TC platform, and the wind turbine generator tooling parametric design is realized by calling the tooling parametric design specification module and the tooling parametric design knowledge base.

[0004] Preferably, the tooling parametric design specification module includes tooling modeling specifications, tooling standard parts modeling specifications, assembly modeling specifications and two-dimensional drawing specifications. The tooling parametric design specification module controls the modeling, assembly and engineering drawing interfaces to be displayed and operated according to the standardized interfaces.

[0005] Preferably, the tooling parametric design knowledge base includes a tooling parametric template library and a typical feature library. The tooling parametric template library is set on the TC platform. The tooling parametric template library customizes unique tooling three-dimensional and two-dimensional parametric templates and control parameter tables for different tooling based on the design rules of each tooling of the wind turbine motor. During design, the tooling parametric design platform drives and calls the tooling parametric template library, and uses historical templates to quickly design the tooling. The typical feature library stores several typical feature models established according to the typical characteristics of the wind turbine motor.

[0006] Preferably, the tooling parametric design platform is secondary developed through the NX platform, and also includes a tooling parameter display module, a historical data query module and a matching degree query module. The historical data query module, the tooling parameter display module and the matching degree query module are linked to each other, and the tooling parametric templates in the tooling parametric template library are filled with specific values. The historical data query module searches for the value of the same template in the historical design process, sets the matching degree according to the similarity between the current template value and the historical template value, and sorts the historical tooling according to the matching degree.

[0007] Preferably, the tooling parametric design platform is secondary developed through the NX platform and also includes a tooling retrieval module. The tooling retrieval module sets a number of retrieval conditions according to the product characteristics of the wind turbine generator. The retrieval method is fuzzy retrieval, and the tooling model in the tooling parametric design knowledge base can be quickly queried and called through the retrieval.

[0008] Preferably, the tooling parametric design platform is secondary developed through the NX platform, and also includes a product design drawing module. The product design drawing module obtains the product model parameters and product model in the TC platform, displays them in the tooling parametric design interface, and realizes the parametric linkage of product and tooling. It also includes a tooling parameter display module. The tooling parameter display module is used to display the tooling template and fill in the specific parameters of the tooling template, and change the tooling parametric design model in real time. It also includes a product parameter display module. The product parameter display module is used to display product parameters and facilitate tooling template calling. It also includes a project query module. The project query module is a customized development function based on the wind turbine tooling design mode. All tools of the same project can be classified through project query. It also includes a tooling model reference module. The tooling model reference module is set in the NX design platform and directly calls the tooling parametric model in the TC platform for rapid design and assembly. It also includes a product model reference module. The product model reference module is set in the NX design platform and directly calls the product model in the TC platform for tooling assembly inspection. It also includes a compliance check module. The compliance check module integrates tooling design specifications and NX The Checkmate function determines whether the tooling design process meets the tooling design specification rules and checks whether tooling assembly interference occurs in the tooling product assembly.

[0009] Preferably, the tooling parametric design platform is secondary developed through the NX platform and also includes a tooling template schematic module. The interface of the tooling template schematic module is used to display the two-dimensional parameter model drawings of the tooling. The parameter codes on the drawings correspond one-to-one to the tooling parameter template models. Since there is relevant design experience in the wind turbine tooling design process, a tooling design experience reminder tool is added to the tooling template schematic interface. Relevant design experience rules can be displayed by clicking on the relevant size position. It also includes a product model schematic module. The product model schematic module is used to display the product design model, and the model values ​​correspond one-to-one to the product design parameters.

[0010] Preferably, it also includes a material library and an automatic property update tool, which includes a material library tool and an attribute tool. The material library tool assigns materials in the tooling material library to corresponding assemblies and parts through an assignment key. The attribute tool updates the weight with one click, which solves the problem that the tooling model changes but the model weight and material cannot be changed, thereby improving the efficiency and accuracy of tooling design.

[0011] Preferably, it also includes a technical requirement library tool, which selects the corresponding product type according to the tooling type and selects the technical requirements of the relevant tooling according to keyword search.

[0012] Based on the aforementioned design method for the parametric rapid design platform of tooling for wind turbine generators, the steps include: a. Tooling designers obtain design resources based on design task objectives; b. Use the tooling parametric rapid design platform to search and find out whether there are historical identical toolings. According to the search matching degree, the toolings are divided into completely identical toolings, partially identical toolings, and completely different toolings; c. If the tooling is exactly the same, directly borrow the design of the tooling; d. If some of the same tooling is used, the design can be divided into two ways. The first way is to drive the tooling with full parameters, and the tooling design can be realized by changing the parameter values; e. The second type is partial parameter tooling and partial feature design, which requires operations including but not limited to adding holes or stretching in the template to realize the tooling design; f. For completely different tooling, there is no similar template in the tooling knowledge base, so a new template needs to be created, and subsequent tooling design will be based on this template.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up a parametric rapid design platform for tooling of wind turbine generators and a corresponding design method, an association relationship between the tooling design of wind turbine generators and the corresponding product model of wind turbine generators is established, the linkage control of the key dimensions of the tooling model and the product design dimensions is realized, and the design process is optimized; at the same time, by setting up material library tools, attribute tools, and technical requirements library tools, the material library tool assigns values ​​to parts and assemblies respectively, the attribute tool quickly updates the tooling weight, and the technical requirements library tool quickly selects the technical requirements of the tooling, thereby improving the tooling design efficiency.

[0021] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiments of the present invention, such as Figure 1-4 A wind turbine generator tooling parametric rapid design platform and design method, including a wind turbine generator tooling parametric design platform, the tooling parametric design platform including a tooling parametric design specification module and a tooling parametric design knowledge base. Figure 2 As shown, the tooling parametric design platform for wind turbine generator is established on UG software, the tooling parametric design specification module and the tooling parametric knowledge base are stored in the TC platform, and secondary development is carried out based on UG software to create an association with the TC platform. Through an intuitive and easy-to-operate user interface, the tooling parametric design specification module, the tooling parametric design knowledge base and other functions can be quickly called from the TC platform to meet the needs of rapid parametric design of wind turbine generator tooling.

[0023] The tooling parametric design specification module is the specification and criterion of the design process. The tooling parametric design specification module is composed of the tooling design rules of the wind turbine generator, including tooling modeling specifications, tooling standard parts modeling specifications, assembly modeling specifications, two-dimensional drawing specifications and other parts. Through customized development, relevant knowledge is integrated into the specific operation of the tooling parametric design platform, such as customized three-dimensional modeling interface, two-dimensional drawing specifications, etc., so as to control the modeling, assembly, and engineering drawing interfaces to display and operate according to the standardized interfaces.

[0024] The tooling parametric design knowledge base includes a tooling parametric template library and a typical feature library. The tooling parametric template library is secondary developed based on the local parametric design function of the NX software. First, based on the design rules of each tooling of the wind power generator on the NX platform, unique tooling three-dimensional and two-dimensional parametric templates and control parameter tables are customized for different toolings, wherein the control parameter table is used to store the values ​​in the parametric template. The two-dimensional parametric template has an associated relationship with the three-dimensional parametric template. As the three-dimensional template changes, the two-dimensional template will change accordingly. The control parameter table is saved in the TC platform. During the specific design, the tooling parametric design platform drives and quickly calls the historical templates in the tooling parametric template library. By borrowing the historical templates for rapid tooling design, the newly designed tooling can be directly expanded and saved in the tooling parametric template library. By constantly borrowing and expanding the tooling parametric template library, the reuse rate of tooling design will be continuously improved, thereby greatly improving the efficiency of tooling parametric design.

[0025] The typical feature library sorts out the relevant typical features of the wind turbine according to the tooling characteristics of the wind turbine, establishes a typical feature model according to the typical features of the wind turbine, and saves the typical features in the typical feature library. During use, the wind turbine model in the typical feature library is directly dragged to the tooling, and scaled and rotated as needed to meet the actual tooling requirements.

[0026] Since wind turbine tooling has several special features, and these special features do not have specific position rules, conventional parameter drive cannot meet its modeling conditions. Therefore, the typical feature library can be used to quickly establish typical features to quickly build the model. Wind turbine tooling is often large in structure and heavy in weight. When assembling with the motor, it is often accompanied by weight requirements. In order for the tooling to meet the requirements, it is often necessary to establish some features for removal. By establishing the typical feature library, weight can be reduced quickly, greatly improving the efficiency of tooling design.

[0027] like Figure 4 As shown, the tooling parametric design platform is developed through the secondary development of the NX platform, and also includes tooling retrieval module, product design drawing module, tooling parameter display module, product parameter display module, project query module, historical data query module, matching query module, tooling model reference module, product model reference module, compliance check module, tooling template schematic module, product model schematic module and other modules. The specific functions of each module of the tooling parametric design platform are as follows: The tooling search module sets four search conditions according to the product characteristics of the wind turbine generator, and the search method is fuzzy search, in which the product type, process and model are set as drop-down menu selection according to the characteristics of the wind turbine generator tooling for tooling designers to choose. Through the search, tooling design models in the tooling parametric design knowledge base can be quickly queried and called; The product design drawing module can obtain the model parameters and product model of the product model in the TC platform, and display them in the tooling parametric design interface for the parametric linkage design of the product and tooling; The tooling parameter display module is used to display the tooling template and fill in the specific parameters of the tooling template, and change the tooling parameterized design model in real time; The product parameter display module is used to display product parameters to facilitate tooling template calling; The project query module is a customized development function based on the wind power generator tooling design mode. All tooling of the same project can be classified through project query.

[0028] The historical data query module, the tooling parameter display module and the matching degree query module are used in conjunction. First, the tooling parameter template in the tooling parameter template library is filled with specific values. Then, the historical data query button can be clicked to find out from the historical data query module whether the same template has designed the same or similar values ​​in the historical design process. The matching degree is set according to the similarity between the current template value and the historical template value, and the historical tooling is sorted according to the matching degree. When designing tooling, the historical tooling with a high matching degree can be directly borrowed or referenced to realize the rapid design of tooling; The tooling model reference module can directly call the tooling parametric model in the TC platform and place it in the NX design platform for rapid design and assembly; The product model reference module can directly call the product model in the TC platform and place it in the NX design platform for tooling assembly inspection; The compliance check module integrates the tooling design specification and NX Checkmate functions, through which it can check whether the tooling design process meets the tooling design specification rules and check whether tooling assembly interference occurs in the assembly of tooling products; The interface of the tooling template schematic diagram module is used to display the two-dimensional parameter model drawings of the tooling. The parameter codes on the drawings correspond one-to-one to the tooling parameter template models. Since there is relevant design experience in the design process of wind turbine tooling, a tooling design experience reminder tool is added to the tooling template schematic diagram interface. The relevant design experience rules can be displayed by clicking the relevant size position; The product model schematic diagram module is used to display the product design model, and the model values ​​correspond to the product design parameters one by one.

[0029] It also includes a material library and property automatic update tool and a technical requirements library tool. The material library and property automatic update tool include a material library tool, a property tool, such as Figure 5 As shown, the material library tool assigns the materials in the tooling material library to the corresponding assemblies and parts through the assignment key, which greatly saves design time.

[0030] The property tool updates the weight with one click, which solves the problem that the weight and material of the tooling model cannot be changed when the tooling model is changed, and improves the efficiency and accuracy of tooling design.

[0031] like Figure 6 As shown, the technical requirement library tool can select the corresponding product type through the tooling type, such as double-fed and semi-direct drive types. The technical requirements of the relevant tooling can be directly selected according to the keyword search. The technical requirements are saved to the background with expansion function, and the content of the technical requirement library can be modified in accordance with the specifications, thereby ensuring the accuracy of the specifications and improving the efficiency of tooling design.

[0032] Combined with the design characteristics of wind turbine tooling, the basic process of wind turbine tooling design is improved. Based on the above principles and design platform, the corresponding tooling parametric design method is formed, such as Figure 1 As shown, the specific process is as follows: a. Tooling designers obtain design resources based on design task objectives; b. Use the tooling parametric rapid design platform to search and find out whether there are historical identical toolings. According to the search matching degree, the toolings are divided into completely identical toolings, partially identical toolings, and completely different toolings; c. If the tooling is exactly the same, directly borrow the design of the tooling; d. If some of the same tooling is used, the design can be divided into two ways. The first way is to drive the tooling with full parameters, and the tooling design can be realized by changing the parameter values; e. The second type is partial parameter tooling and partial feature design, which requires operations including but not limited to adding holes or stretching in the template to realize the tooling design; f. For completely different tooling, there is no similar template in the tooling knowledge base, so a new template needs to be created, and subsequent tooling design will be based on this template.

[0033] like Figure 3 As shown in the figure, the design is realized by establishing the association between the product and the tooling model. The specific functions are built on the tooling parametric rapid design platform. The specific process is as follows: The product model is archived in the TC platform. By clicking the Get Design Drawing Parameter Information button on the interface of the tooling parametric design platform, the product model parameters and product template schematic diagram in the TC platform are called, and the product model parameters and product template schematic diagram are respectively displayed on the interface of the tooling parametric design platform.

[0034] When designing tooling, by observing the product model, the relationship between tooling and product dimensions can be found. The key dimensions of the tooling directly reference the key parameters of the product, thereby realizing the linkage between the tooling drawings and the product drawings. Through this operation, subsequent changes in the product model will directly drive changes in the tooling model, improving the accuracy of tooling model design.

[0035] Then, you can click the product model reference key and the tooling model reference key to call the product model and tooling model to the NX assembly interface for assembly. After completing the assembly, click the compliance check to pass the compliance check. Determine the rationality of the linkage between tooling and products to prevent unreasonable tooling design. Check whether the tooling design is reasonable. If it is reasonable, complete the design. If it is unreasonable, change the parameters again until the design requirements are met.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
