Background Art

[0002] In the field of machine tools, most of the main parts of planer-type milling and boring machines with a rear column form are fixed. The tailstock of the rear column is manually adjusted concentric with the spindle. During the processing, one end of the long tool shank is clamped on the spindle, and the other end is supported on the slide rest end to make a high-speed rotational movement. The multi-section hole processing of deep cavity parts is realized through the feed of the workbench. The traditional processing method is to rotate the workbench 180° after boring one side of the hole and then bore the hole on the other side. Due to the influence of the rotation accuracy of the rotating workbench and the vertical accuracy of the machine tool bed, etc., the coaxial accuracy of the holes processed in batches will be reduced after the superposition of various accuracy deviations, and the production efficiency is low.

The length direction of the rear column 20 is parallel to the length direction of the column 12. In this embodiment, the rear column 20 is integrally formed by welding steel parts. The rear column 20 stands on the foundation base surface through a floor anchor and is flush with the bottom surface of the machine tool bed.

[0030] The slide 30 is movably installed on the rear column 20. The slide 30 and the main shaft 11 are at the same horizontal height.

[0031] The tool component 40 includes a tool bar 41 and a plurality of tools 42. One end of the tool bar 41 is installed on the main shaft 11.

The plurality of tools 42 are distributed on the tool bar 41 along the axial direction of the tool bar 41 and are located in the multi-stage hollow inner cavity hole. In this embodiment, the length direction of the rear column 20 is perpendicular to the axis direction of the tool bar 41.

[0032] The Z-axis drive assembly 50 drives the column 12 to move along the axial direction of the tool bar 41, and the main shaft 11 drives the tool bar 41 to rotate, so that the tool 42 can perform multi-segment hole machining on the workpiece.

In this embodiment, the movement of the slide block 30 on the rear column 20 is controlled by a servo system, eliminating the need for manual centering, greatly reducing the labor cost and time cost, and improving the production efficiency.

[0034] The wear-resistant sleeve 70 is embedded inside the slide block 30, and the tool bar 41 passes through the wear-resistant sleeve 70 and extends out. The wear-resistant sleeve 70 has excellent wear resistance, and the wear-resistant sleeve 70 has a self-lubricating function, ensuring the reliability of the long-term operation of the equipment. In this embodiment, an oil injection hole is provided on the wear-resistant sleeve 70 to meet the needs of long-term machining.

[0035] This application also provides a multi-segment hole machining structure for a planer-type milling and boring machine, including a workbench 80 and the above-mentioned multi-segment hole machining tooling for a planer-type milling and boring machine. A workpiece is installed on the workbench 80, and the workpiece is provided with a multi-segment hollow inner cavity hole. One end of the tool bar 41 is installed on the main shaft 11, and the other end of the tool bar 41 passes through the multi-segment hollow inner cavity hole and the slide block 30 and extends out. A plurality of tools 42 are distributed along the axial direction of the tool bar 41 and are located inside the multi-segment hollow inner cavity hole. The Z-axis drive assembly 50 drives the column 12 to move along the axial direction of the tool bar 41, and the main shaft 11 drives the tool bar 41 to rotate, so that the tool 42 can perform multi-segment hole machining on the workpiece, thereby improving the coaxial accuracy of the holes.
