Description

Technical Field

[0001] The present invention relates to the technical field of process design, and in particular to a typical three-dimensional tooling library and a tooling design method based on a digital process platform. Background Art

[0002] In the manufacturing field, process technology is a key link supporting products from research and development to assembly, among which tooling design is an important part of process technology. The design cycle and quality directly determine production efficiency, product quality and delivery cycle. It plays an important role in ensuring product quality, improving production efficiency and safe and civilized production. It is an important indicator of the level of process technology.

[0003] When products enter the small batch and multi-variety mode, their manufacturing cycle is tight, and the types and quantity of tooling are constantly increasing. In the existing process technology manufacturing field, for example, motor manufacturing process technology includes material heat treatment, machining, welding, casting, assembly, wiring, testing and other manufacturing process specialties, which are distributed in various processes of the motor product production cycle, such as coil manufacturing, core lamination, stator assembly, rotor assembly, motor assembly process, etc. The process technology of each process supports its assembly and manufacturing capabilities, and the quality of tooling design and manufacturing has a great impact on the quality and efficiency of product manufacturing.

[0004] The traditional tooling design method has the following shortcomings: 1) There is a low degree of commonality and modularization of new product tooling, and the design and manufacturing cycle is long, which cannot effectively meet the on-time delivery of products; 2) The typical structure of tooling design has not been effectively shared, the tooling borrowing rate and the possibility of modification are low, some tooling parts are repeatedly designed and manufactured, and the tooling costs remain high; 3) Some tools are stored at the production site for a long time, and the utilization rate of tooling parts is low; 4) Improvements during on-site use are not reflected in the subsequent tooling design, and it is impossible to achieve continuous optimization and improvement of the tooling structure to improve the use effect of the tooling. Summary of the invention

[0005] In order to solve the above-mentioned problems in traditional tooling design, the present invention provides a new typical three-dimensional tooling library and tooling design method based on a digital process platform.

[0006] The present invention is achieved by adopting the following technical solutions: The typical three-dimensional tooling library based on the digital process platform includes the hierarchical construction of typical structural tooling, the review and evaluation of typical structural tooling, the storage of typical structural tooling, the retrieval and call of the typical structural tooling library, and the maintenance and update of the typical structural tooling library; Typical structural tooling is constructed in layers: Typical structural tooling is selected and extracted from the tooling of key processes in the product manufacturing process based on the process professional framework. When constructing typical structural tooling in layers, it is constructed in layers step by step according to the typical tooling library, manufacturing unit, professional category, process, and related typical structural tooling types. In the specific implementation, the planned typical structural tooling library framework is as follows: Level 1: Typical tooling library; Level 2: Manufacturing units such as basic process, motor process, electrical process, test process, etc. Level 3: 27 majors including cold stamping, machining, winding manufacturing, and assembly; Level 4: Processes such as shipping packaging, finishing, motor testing, final assembly, stator assembly, rotor assembly, varnishing, wire embedding, coil, commutator, lamination, welding, machining, converter testing, assembly, wiring, etc. 44 processes; Level 5: Related typical structural tooling; The tooling library framework is built according to the levels of manufacturing units, specialties, and processes, and a standard system for evaluating the entry of typical structural tooling into the library is formulated. Typical tooling is sorted out and refined according to requirements and standards, and finally confirmed by process experts. The two-dimensional drawings, three-dimensional drawings, and key parameter lists of typical tooling that meet the requirements are entered into the system. Subsequent tooling design refers to typical structural tooling to achieve simplification, standardization, and serialization of tooling design; Evaluation of typical structural tooling, including functional description, typical description and evaluation standard description. Functional description includes tooling function, usage method, technical parameters, interface size. Typical description includes tooling innovation, serialized modular design, reliability, verification status, and pain points and difficulties solved. Evaluation standard description includes innovation, serialized modularization, reliability, improvement and optimization. Invite process technology experts, on-site crafts, senior technicians, quality inspectors and other judges to review the typicality of tooling with reference to the evaluation standards. For typical structure tooling, a typical structure tooling library framework is established. According to the principle of stratification, the typical tooling warehousing details are formulated, and then opinions are collected, the typical tooling warehousing details are revised and issued. The typical structure tooling warehousing review instructions are compiled and reviewed for warehousing. If the review is unqualified, the typical structure tooling warehousing review instructions are recompiled until the warehousing review is qualified. If the review is qualified, the typical structure 2D / 3D drawing is drawn for warehousing. Among them, when adding or improving the typical structure, the typical structure tooling warehousing review instructions are also required to be recompiled and reviewed for warehousing. Retrieve and call the typical structure tooling library, enter the key size parameters of typical tooling into the list, and continuously enrich the typical tooling library. When designing tooling, the tooling can be quickly retrieved through the key size parameter list of typical structure tooling, and typical structure tooling that meets the conditions can be found. The 3D model can be directly borrowed or used for modification, so as to realize rapid tooling design and simplification, standardization and serialization of tooling design; The typical structure tooling library is maintained and updated. In terms of tooling design, when designing new tooling, if it is found that the used modules are not in the existing tooling library, the module design must be added. At the same time, when adding new modules to the tooling module library, the corresponding tooling designer must classify and design the modules and revise the corresponding tooling structure library. If there are similar modules with modified sizes, the modified series of tooling can be directly put into the library. In terms of tooling changes, the process designers put forward the reasons for the changes of typical tooling, organize experts to review the typical tooling, and determine the feasibility of the changes of typical tooling. For typical tooling that has passed the change application, the typical tooling library management personnel maintain the typical tooling in the library. In terms of tooling management, the typical tooling in the typical tooling library is regularly evaluated for its usage, the adoption rate of typical tooling is statistically analyzed, and typical tooling with no use value is managed out of the library.

[0007] Furthermore, the key dimension parameters of typical structural tooling described in the typical structural tooling library retrieval call include tooling number, tooling name, tooling application scope, key dimensions, and interface dimensions.

[0008] Furthermore, the tooling number is named as GZ+process specialty classification number+specific process specialty number+typical tooling sub-library number+typical tooling number+typical tooling series number. The naming and numbering of typical tooling is based on the number of the typical tooling sub-library, and at the same time, a three-digit sequence number is added according to the different tooling structures and usage characteristics. On this basis, in order to distinguish between typical tooling and series of chemical tools designed with reference to the typical tooling, the typical tooling series number is a three-digit series number sequence number added after the typical tooling number, such as 000 is the typical tooling number, 001, 002... are typical tooling designed with reference to the typical tooling number.

[0009] The tool design method based on the digital process platform includes the following steps: 1) determining the type of tool to be designed; 2) consulting a typical three-dimensional tool library according to the determined type of tool; 3) searching for key size parameters to determine whether the tool can be borrowed; if it can be borrowed, directly borrow it and verify the tool status (it is well known to those skilled in the art that the tool status refers to whether the tool interface is worn, whether the tool is intact and can be directly borrowed, etc.); if it cannot be borrowed, determining whether there is a possibility of modification; if it can be modified, calling the tool from the typical three-dimensional tool library, modifying the parameters and dimensions of the tool, thereby completing the modified tool design; if it cannot be modified, designing the tool completely, thereby completing the completely new tool design; Furthermore, in step 3), when the modified tooling or the new tooling design is completed, it is necessary to analyze and statistically analyze the interface dimensions of the designed modified tooling or the new tooling and unify them, and update the typical three-dimensional tooling library to facilitate subsequent tooling design.

[0010] The beneficial effects produced by the present invention are as follows: 1) Using digital process technology as a platform, modularization and serialization as the idea, design, manufacture and verify tooling, complete the establishment of a modular universal design model library for tooling, establish a three-dimensional model library of typical structural tooling for professional key processes in the resource library, and mark and explain the key characteristics and functions of each part of the model. When designing new product tooling, refer to typical tooling to achieve modular, standardized and universal design, provide tooling design applications for new product applications, standardize tooling design drawings, improve tooling design efficiency, and avoid repeated design of tooling parts. The improvement content of the subsequent tooling application process will be promptly fed back to the typical structural tooling three-dimensional model library to improve the tooling versatility and selection combination design mode, realize the possibility of increasing the tooling borrowing rate and restructuring, and realize the process of tooling from design to maintenance throughout the entire life cycle; 2) The tooling design method aims to streamline the tooling design, tooling manufacturing, tooling use, tooling management, and continuous improvement throughout its entire life cycle, from design to management and maintenance. It aims to reduce the number of tools, shorten the manufacturing cycle, and reduce tooling storage from the source of tooling design, thereby improving tooling design efficiency and tooling technical management level, enhancing the versatility of tools, and providing support for the realization of intelligent manufacturing.

It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] The construction of a typical three-dimensional tooling library based on a digital process platform includes the hierarchical construction of typical structural tooling, the review and evaluation of typical structural tooling, the storage of typical structural tooling, the retrieval and call of the typical structural tooling library, and the maintenance and update of the typical structural tooling library, such as Figure 1 As shown; Typical structural tooling is constructed in layers: Typical structural tooling is selected and extracted from the tooling of key processes in the product manufacturing process based on the process professional framework. When constructing the typical structural tooling in layers, it is constructed in layers step by step according to the typical tooling library, manufacturing unit, professional category, process, and related typical structural tooling types. In the specific implementation, the planned typical structural tooling library framework is as follows: Figure 2 As shown: Level 1: Typical tooling library; Level 2: Manufacturing units such as basic process, motor process, electrical process, test process, etc. Level 3: 27 majors including cold stamping, machining, winding manufacturing, and assembly; Level 4: Processes such as shipping packaging, finishing, motor testing, final assembly, stator assembly, rotor assembly, varnishing, wire embedding, coil, commutator, lamination, welding, machining, converter testing, assembly, wiring, etc. 44 processes; Level 5: Related typical structural tooling; Build a tooling library framework according to the levels of manufacturing units, specialties, and processes, and formulate a typical structural tooling library evaluation standard system such as Figure 3 As shown in the figure, typical tooling is sorted out and refined according to requirements and standards, and finally confirmed by process experts. The two-dimensional drawings, three-dimensional drawings and key parameter lists of typical tooling that meet the requirements are entered into the system. The subsequent tooling design refers to the typical structural tooling to achieve simplification, standardization and serialization of tooling design. Typical structural tooling review and evaluation, such as Figure 3 As shown, it includes functional description, typical description and evaluation standard description. Functional description includes tooling function, usage method, technical parameters, interface size. Typical description includes tooling innovation, serialized modular design, reliability, verification status, and pain points and difficulties solved. Evaluation standard description includes innovation, serialized modularization, reliability, improvement and optimization. Invite process technology experts, on-site crafts, senior technicians, quality inspectors and other judges to review the typicality of tooling with reference to the evaluation standards. For typical structure tooling, a typical structure tooling library framework is established. According to the principle of stratification, the typical tooling warehousing details are formulated, and then opinions are collected, the typical tooling warehousing details are revised and issued, and the typical structure tooling warehousing review instructions are compiled and reviewed for warehousing. If the review is unqualified, the typical structure tooling warehousing review instructions are recompiled until the warehousing review is qualified. If the review is qualified, a typical structure 2D / 3D drawing is drawn for warehousing. Among them, when adding or improving the typical structure, it is also necessary to re-compile the typical structure tooling warehousing review instructions and conduct a warehousing review, such as Figure 4 As shown; Retrieve and call the typical structure tooling library, enter the key size parameters of typical tooling into the list, and continuously enrich the typical tooling library. When designing tooling, the tooling can be quickly retrieved through the key size parameter list of typical structure tooling, and typical structure tooling that meets the conditions can be found. The 3D model can be directly borrowed or used for modification, so as to realize rapid tooling design and simplification, standardization and serialization of tooling design; The typical structure tooling library is maintained and updated. In terms of tooling design, when designing new tooling, if it is found that the tooling module used is not in the existing tooling library, the module design must be added. At the same time, when adding a new module to the tooling module library, the corresponding tooling designer must classify and design the modules and revise the corresponding tooling structure library. If there are similar modules with modified dimensions, the modified series of tooling will be directly put into the library; in terms of tooling changes, the process designers will propose reasons for changing the typical tooling, organize experts to review the typical tooling, and determine the feasibility of the typical tooling changes. For typical tooling that has passed the change application, the typical tooling library manager will maintain the typical tooling in the library; in terms of tooling management, the typical tooling in the typical tooling library will be regularly evaluated for its usage, the adoption rate of typical tooling will be counted, and typical tooling with no use value will be managed out of the library.

[0019] In specific implementation, the key dimension parameters of typical structural tooling described in the typical structural tooling library search call include tooling number, tooling name, tooling application scope, key dimensions, and interface dimensions, such as Figure 5 shown.

[0020] When implementing it, Figure 6 As shown, the tool number is named GZ + process specialty classification number + specific process specialty number + typical tool sub-library number + typical tool number + typical tool series number. The naming and numbering of typical tools are based on the number of the typical tool sub-category library in which they are located, and at the same time, the three-digit sequence number is added according to the different tool structure and usage characteristics. On this basis, in order to distinguish the typical tool from the series of chemical tools designed with reference to the typical tool, the typical tool series number is to add a three-digit series number sequence number after the typical tool number, such as 000 is the typical tool number, 001, 002... are the typical tools designed with reference to the typical tool number.

[0021] like Figure 7 As shown in the figure, the tool design method based on the digital process platform includes the following steps: 1) determining the type of tool to be designed; 2) consulting a typical three-dimensional tool library according to the determined type of tool; 3) searching for key size parameters to determine whether the tool can be borrowed. If it can be borrowed, directly borrow it and verify the tool status. If it cannot be borrowed, determine whether there is a possibility of modification. If it can be modified, call the tool from the typical three-dimensional tool library, modify the parameters and size of the tool, and thus complete the modified tool design. If it cannot be modified, design the tool anew, and thus complete the new tool design. In the specific implementation, in step 3), when the modified tooling or the new tooling design is completed, it is necessary to analyze and statistically analyze the interface dimensions of the designed modified tooling or the new tooling and unify them, and update the typical three-dimensional tooling library to facilitate subsequent tooling design, retrieval and calling.

[0022] The above is only a specific implementation of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
