The requirements of precision hardware structure design are multi-faceted. These requirements are designed to ensure the rationality, feasibility, economy of the design, and the quality and performance of the product. The following are some of the main demand points: 1. Functional requirements to meet the use function: First of all, the precision hardware structure design must meet the functional requirements of the product, such as connection, fixing, transmission, positioning, etc. Stable performance: The design should ensure that the product can work stably and reliably under various working conditions, including the requirements of strength, stiffness, wear resistance, corrosion resistance, etc. 2. Process requirements are easy to process: The structural design should consider the processing performance of the material, try to use the shape and size that are easy to process, and reduce the production cost. Convenient assembly: When designing, it is necessary to consider the assembly sequence and method of parts to ensure that the assembly process is simple and fast, and reduce the difficulty and cost of assembly. 3. Economic demand cost control: On the premise of meeting functional and process requirements, try to optimize the structure, reduce material consumption and processing difficulty, so as to reduce production costs. Standardization: Try to use standard parts and general parts, reduce the design and manufacture of non-standard parts, and improve production efficiency and economic benefits. 4. Safety requirements Structural safety: The safety and stability of the structure should be considered when designing to prevent safety accidents caused by structural defects. Protection design: For parts that may cause harm to the human body, corresponding protective measures should be designed, such as safety covers, protective nets, etc. 5. Accuracy Requirements Dimensional Accuracy: Precision hardware products usually have high requirements for dimensional accuracy. The dimensional tolerance and fit accuracy of each component should be clearly defined when designing. Shape Accuracy: For components that need to ensure shape accuracy, such as gears, shafts, etc., appropriate processing methods and process measures should be considered when designing. 6. Maintenance and Maintenance Ease of Maintenance: The maintenance and maintenance needs of the product should be considered when designing, so as to facilitate the replacement of wearing parts and daily maintenance. Durability: Improve the service life of the product through reasonable structural design and reduce the frequency of repair and replacement. 7. Environmental Adaptability Environmental Adaptability: The working environment and use conditions of the product should be considered when designing, such as temperature, humidity, corrosiveness, etc., to ensure that the product can work normally in various environments. 8. Design and manufacturing coordination: Design should fully consider the existing manufacturing capacity and process level to ensure that the design scheme can be successfully realized and meet production requirements.
