Every thing has its classification. The classification is just to give everyone a better choice. When choosing, it can be used for customers and businesses to make a better choice. Mechanical parts are one of them. Then the classification of mechanical parts is What kinds of classifications are there? Let me explain to you the editor of precision parts processing.
A mechanical part is composed of several surfaces. To study the relative relationship of the surface of the part, a datum must be determined. The datum is the point, line, and surface on which the position of other points, lines, and surfaces are determined on the part. According to the different functions of benchmarks, benchmarks can be divided into design benchmarks and process benchmarks.
1. Design basis
The datum used to determine the position of other points, lines and surfaces on the part drawing is called the design datum. As shown in Figure 32-2 [cc2], the design reference of each outer circle and inner hole is the axis line of the part, end face A is the design reference of end faces B and C, and the axis of the inner hole is the outer diameter Benchmark to jump.
2. Process benchmark
The datum used in the process of processing and assembling the part is called the process datum. Process benchmarks are divided into assembly benchmarks, measurement benchmarks and positioning benchmarks according to different uses.
The above is the classification of mechanical parts. From the above text, we can understand that there are several classifications, and its benchmark is divided into two benchmarks, these two things It has different functions.
