Description

Technical Field

[0002] In modern manufacturing, the boring process of drive axle housing is a key process that directly affects the driving performance and safety of the vehicle. Traditional boring processes mainly rely on manual operation or simple mechanized equipment. Although these methods can meet basic needs, they have great limitations in terms of accuracy, efficiency and stability. With the improvement of industrial automation level, CNC machine tools and special boring devices have gradually become the mainstream choice, greatly improving production quality and efficiency. However, even in a highly automated environment, how to ensure the stability of the tool and the precise positioning of the workpiece during the boring process is still an urgent problem to be solved.

[0003] During the boring process of the drive axle housing, the tool is prone to vibration and deviation when running at high speed, resulting in a decrease in processing accuracy. Since the tool itself rotates at too high a speed and when boring parts, the tool contacts the inner wall of the axle housing and is subjected to a large impact force, it is very easy to cause the tool to vibrate during operation, thereby affecting the processing quality of the workpiece surface. In more serious cases, during the boring process, the tool itself will be aggravated in wear, causing the tool to break and be damaged during processing, thereby affecting the service life of the tool.

[0004] In view of the above-mentioned related technologies, it is necessary to propose a boring device for a drive axle housing to solve at least one of the above-mentioned technical problems. Summary of the invention
