The difference between components and parts
The two words components and parts are the most commonly used in factories and are also the easiest to use. Confusing concepts.
Generally speaking: a component (package) is a collection of related parts. Refers to parts that are inseparable and lose their original functions after being disassembled.
Parts refer to two or more parts connected by standard parts and can be disassembled.
It seems that I still can’t explain it clearly.
Just copy a section of the book:
Composition of machinery:
Assembly of components and components
A mechanical product is often composed of Composed of thousands to tens of thousands of parts, in order to facilitate the organization of assembly work, the product must be decomposed into several assembly units that can be assembled independently so that assembly can be carried out in accordance with the unit sequence and help shorten the assembly cycle. Assembly units are generally divided into five levels.
1. Parts Parts are the most basic units that make up machinery and participate in assembly. Most parts are pre-assembled into assemblies, assemblies and subassemblies before entering final assembly.
2. Assemblies are assembly units that are one level larger than parts. The following situations are all combined items.
(1) Two or more parts are connected together by non-detachable connection methods (such as riveting, welding, hot press assembly, etc.).
(2) A few parts need to be combined and processed after being assembled, such as the gear reduction box and box cover, diesel engine connecting rod and connecting rod cover. They are all bored after being assembled. The parts are aligned and cannot interact with each other. Change.
(3) Combine a basic part and a few parts,
3. Component A component is a combination of one or several assemblies and several parts.
4. Component A component is composed of a reference part and several components, parts and parts. Such as spindle box, tool box, etc.
5. Mechanical product It is a whole composed of all the above assembly units.
