What Is Mechanical Assembly?

Mechanical assembly refers to the realization of the connection of mechanical parts or components in accordance with the technical requirements of the design, and the combination of mechanical parts or components into a machine. Mechanical assembly is an important part of machine manufacturing and repair, especially for mechanical repair, because the provision of assembled parts is conducive to the situation of mechanical manufacturing, and makes assembly work special. The quality of the assembly work plays a very important role on the efficiency of the machine, the duration of the repair, the labor and cost of the work.

Mechanical assembly

The process of mating and connecting parts or components according to specified technical requirements to make them into semi-finished products or finished products is called

Assembly technology has been developed with increasing requirements for product quality and increasing production batch sizes. In the early stage of the development of the machinery manufacturing industry, assembly operations such as filing, grinding, scraping, hammering and tightening screws were used to make parts fit and join together. At the end of the 18th century, product batches increased and processing quality improved.

Common assembly processes are: cleaning, balancing,

According to product assembly requirements and

In order to ensure effective assembly work, the machine is usually divided into several

According to whether the assembly object moves during the assembly process, it is divided into two types: fixed assembly and mobile assembly.

First, the basic principles of the assembly process

1. Guarantee product assembly quality to extend product life;

2. Arrange the assembly sequence and process reasonably to minimize

In order to ensure the assembly quality of mechanical products, certain environmental conditions are sometimes required at the assembly site, such as the assembly of high-precision bearings or high-precision machine tools (such as coordinate boring machines,

The general development direction of mechanical assembly is:

Improve the structural design of the product according to the production batch to improve the assembly processability of the product;

Using high-power ultrasonic cleaning technology and equipment to effectively clean large parts to improve the cleanliness of the product;

Promote and improve the bonding technology, and develop new technologies that combine processing and assembly, such as bare wire threading (screws are screwed directly into the light holes), non-hole wire threading (without machining holes, and the screw is directly screwed into the connector);

Promote and apply advanced technologies such as optics and lasers to improve product quality and stability in testing and calibration; Increase the degree of mechanization and automation of assembly work.
