[0002] Boring tables are widely used in various machining fields, especially in boring machining occasions with extremely high precision requirements. The design and function of this table make it a powerful assistant in many industrial manufacturing fields. Taking the automotive manufacturing industry as an example, boring tables play a key role in machining automobile engine blocks. Due to the complexity of the internal structure of the engine block, high-precision boring processing is required to ensure the precise fit of each component. Boring tables can meet this requirement and ensure the machining quality of the engine block through its stable support and precise movement control. In addition to the automotive manufacturing industry, boring tables also play a key role in the machining of heavy mechanical parts such as machine tool spindle boxes. The inner hole and end surface machining of these parts require extremely high precision and stability, and boring tables are the ideal choice to meet these requirements. Through precise boring processing, it can ensure that the internal structure of parts such as the spindle box meets the design requirements, thereby ensuring the overall performance and stability of the machine tool.

[0003] The existing boring bar worktable has a fixed length and the boring bar cannot be extended, which limits the processing range of the worktable. When it is necessary to bore deep into the workpiece, the boring bar is not long enough to effectively process, which requires frequent replacement of boring bars of different lengths, which undoubtedly increases the complexity and time cost of the operation. Secondly, the non-extendable boring bar also affects the accuracy and stability of the processing. In some precision processing, the position and stability of the boring bar are extremely high. However, due to the fixed length of the boring bar, it cannot meet the processing requirements of different workpieces, resulting in reduced processing accuracy or unstable workpiece quality.
