The problem that can be solved by designing some special machines is called non-standard mechanical design. Enterprises sometimes encounter special problems in certain stages of production practice, which become bottlenecks in improving labor productivity.

If these bottleneck problems can be solved by designing some special machines, it is undoubtedly a blessing for enterprises. The source of this gospel is a branch of mechanical design - non-standard mechanical design.

Non standard mechanical design generally requires personnel who understand mechanical, electronic, electrical, and other related fields.

Non standard mechanical design:



1、 Characteristics



1. Emphasize the principles of standardization, modularity, and simplicity in design.



2. All products are designed using 3D design software such as Auto CAD and Pro/E, which can generate physical quantities such as volume, weight, and center of gravity of parts and components, providing reliable basis for related design and subsequent processing.



3. All two-dimensional structural diagrams are automatically generated by computers based on three-dimensional digital models, ensuring the accuracy of views and dimensions, and ensuring the harmonious unity of drawing quality and work efficiency.



4. When the design is completed, product renderings in BMP, JPG, and other formats can be output.

2、 Non standard mechanical design advice



1. The things designed by beginners are definitely not perfect enough. You should consult with experienced engineers more, who will generally provide guidance and improve yourself. Those with a strong sense of responsibility may be worried and unable to sleep, as everyone has come from this step. As long as you put in the effort, there will be no problem. Even if there are mistakes, they are inevitable, and it depends on how you make up for them.



2. The mechanical industry is not developing rapidly like the electronics industry, for the simple reason that there are few available principles, and its development is also driven by the electrical industry, which effectively combines machinery with electrical, pneumatic, and hydraulic systems.



3. The things designed must be easy to maintain, so small that there is no place to put the wrench. If it is not feasible, internal hexagonal bolts can be used. Convenient for processing, the design should consider processing issues, such as avoiding drilling holes on curved surfaces as much as possible. If drilling is necessary, it should be done through the center or by first processing the platform before drilling.



4. After the initial design draft is completed, it is necessary to optimize whether there are simpler ways or more advanced components to replace it. For example, if you want to make an electric flatcar, there are DC and AC drives. AC is not very safe, and there are power lines for transmission. DC has high costs and requires rectification devices, but batteries can also be used.



Transporting flatcars requires a very low speed of 60m/min and a high motor speed, usually requiring the use of a gearbox for speed control. However, online research shows that brushless DC motors can achieve a speed of 40r/min, eliminating the need for a gearbox, reducing investment, minimizing fault points, and lowering maintenance costs. This is innovation.
