Problems solved by technology
Boring pins are often used to process such holes. However, due to the harsh processing environment and high processing difficulty, the traditional boring pin processing process is often manually measured and corrected, and it is processed intermittently, which makes the processing accuracy and efficiency extremely low.

The invention discloses a boring pin machining device for a long and straight segmented inner hole. The boring pin machining device comprises a middle support installed in a fixed segment; a boring rod penetrates through a first machining section, the middle support and a second machining section; a first boring cutter holder is arranged on the boring rod and is positioned on the first machining section; a first boring cutter is arranged on the first boring cutter holder; a first adjusting mechanism is mounted on the first boring cutter holder and used for adjusting the radial position of the first boring cutter; a second boring cutter holder is arranged on the boring rod and is positioned on the second machining section; a second boring cutter is arranged on the second boring cutter holder; a second adjusting mechanism is mounted on the second boring cutter holder and used for adjusting the radial position of the second boring cutter; and a third adjusting mechanism is arranged on the middle support and is used for adjusting the radial position of the boring rod. The high-precision automatic boring machining of the long and straight segmented inner hole can be realized.
Description
technical field [0001] The invention relates to the field of boring pin machining for long straight segmented inner holes. Background technique [0002] Large-scale long straight segmented bores widely exist in industrial practice, such as ship segmented stern tubes. Boring pins are often used to process such holes. However, due to the harsh machining environment and high processing difficulty, the traditional boring pin machining process is often manually measured and corrected, and is processed intermittently, resulting in extremely low machining accuracy and efficiency. How to realize the automatic measurement and automatic correction of the machining process, improve the working environment, and improve the machining efficiency and precision has become a difficult problem to be solved in the field of large-scale long straight segmented inner hole machining. Contents of the invention [0003] The object of the present invention is to provide a boring pin processing dev...
