The adjustment contents and methods of geometric accuracy in the application of deep hole drilling machine are as follows:
1. The adjustment of sizing block and anchor bolt is mainly to adjust the geometric accuracy of the machine tool through sizing block and anchor bolt. If necessary, the accuracy requirements can be achieved by slightly changing the inlay and pre tightening roller on the guide rail.
2. Adjust the relative position between the manipulator, the spindle and the tool magazine, so that the machine tool can automatically run to the tool change position, and complete the tool exchange action step by step in a manual way, and check whether the actions such as grabbing, loading, pulling and rotating exchange are accurate and stable.
3. Adjust the relative position of the pallet and the exchange worktable. This kind of machine tool is double worktable or multi worktable. Adjust the relative position of the pallet and the exchange worktable to ensure the stable and reliable automatic exchange of the worktable.
The application scope of deep hole drilling machine mainly includes the following three aspects:
1. Parts that are not easy to be machined on general machine tools, or need to be equipped with complex special clamps on general machine tools and need a long adjustment time to be machined;
2. For the parts that need to be produced in small batch and multiple batches (generally less than 100 pieces), the mold parts with complex contour and shape, high machining accuracy requirements or complex curves and surfaces that must be solved by digital methods, and the parts that need to be remodeled for many times;
3. It is a high-value precision part that needs to be processed by many processes such as boring, milling, drilling, expanding, reaming, spot facer and tapping thread, and can be clamped once
