Briefly describe the functions and characteristics of box parts

The basic part of a machine or component is a box body, which can assemble parts into a whole, such as shafts, sleeves, gears and other parts, and each part can be in the correct position, work in coordination with each other to transmit power, etc., so, The processing quality of the box will directly affect the accuracy, performance and life of the machine or component. Common box body parts include: machine tool headstock, machine tool feed box, gearbox body, reduction box body, engine block and machine base, etc. According to the different structural forms of the box parts, it can be divided into two categories: integral box and separate box. The former is integral casting and integral processing, which is difficult to process, but has high assembly accuracy; the latter can be manufactured separately, which is convenient for processing and assembly, but increases the assembly workload. Although the structure of the box body is diverse, they still have the main characteristics in common: complex shape, thin and uneven wall, cavity shape inside, many processing parts, processing difficulty, existing hole series and high precision requirements Flat, there are also many fastening holes with lower accuracy requirements. Therefore, the mechanical processing labor for box parts in general medium-sized machine tool manufacturers accounts for about 15%-20% of the entire product processing volume.
