Process flow refers to the arrangement of various processes in the production of industrial products, from raw materials to finished products. Also called "processing flow" or "production flow". Referred to as "process". The following is a product assembly process flow chart that I compiled for everyone as a reference. Welcome to read! Product Assembly Process Flow Chart
Assembly Process
Components and product assembly systems. It can indicate the hierarchical relationship between components and product assembly units.
The assembly of products is not just a simple connection of qualified parts, joints, components, and parts. It is ensured through adjustments, repairs, corrections, and repeated inspections according to the technical requirements of the assembly. Technical requirements for assembly. Common assembly work mainly includes:
1) Cleaning
Cleaning work is of great significance to ensure product assembly quality and extend product service life, especially for precision fittings and seals. is important. The purpose of cleaning is to remove oil stains and impurities on the surface of parts. Commonly used cleaning fluids include kerosene, gasoline, alkali and chemical cleaning fluids. Methods include scrubbing, dipping, spray cleaning, ultrasonic cleaning, etc. The type of cleaning fluid and cleaning method should be selected based on the material of the parts to be cleaned, the batch size, and the nature of oil stains and impurities.
2) Connection
There are two ways to connect. One is detachable connection, such as threaded connection, chain connection and pin connection; the other is non-detachable connection, such as welding, Riveting and interference connections, etc.
3) Correction, adjustment and matching
The assembly accuracy of products, especially those with high assembly accuracy requirements or single-piece and small-batch production, completely relies on the interaction between parts. It is difficult, uneconomical, and even impossible to obtain guarantees. The mutual positions of the relevant parts in the product require some alignment and leveling work. Commonly used tools include: square ruler, square ruler, level, optical collimator, etc. In addition to adjusting the mutual positions of the relevant parts, the adjustment work also includes the clearance between the kinematic pair and the mating pair, such as bearing clearance, guide rail clearance, gear meshing clearance, etc. Common matching operations include drilling, reaming, scraping, grinding, etc. Correction, adjustment and coordination are carried out in combination.
4) Balance
For products or components with high rotational speed and high motion balance requirements, balancing work must be performed during assembly. Static balancing or dynamic balancing can be performed as needed. Methods for adjusting the balance include adding mass, removing mass, changing the position of the balance weight, etc.
5) Testing and acceptance
