Abstract

The invention provides a deep hole machining boring bar which comprises a cylinder, a boring cutter mechanism is movably arranged on the cylinder, the boring cutter mechanism comprises a sliding sleeve and a turning tool, the sliding sleeve is movably arranged on the cylinder in a sleeving mode and slides in the length direction of the cylinder, and the turning tool is arranged on the sliding sleeve; the boring cutter mechanism further comprises a lead screw rotationally arranged in the cylinder in the length direction of the cylinder, the central axis of the lead screw coincides with the central axis of the cylinder, the lead screw rotates with the central axis of the cylinder as the center, the lead screw is sleeved with a threaded sleeve in a threaded mode, and a sliding groove is formed in the cylinder in the length direction of the cylinder in a penetrating mode. The threaded sleeve is connected with the sliding sleeve through a connecting plate, and the connecting plate slides in the sliding groove. The cylinder rotates to drive the sliding sleeve and the lead screw to rotate, and the sliding sleeve can be driven to slide in the length direction of the cylinder, so that the turning tool arranged on the sliding sleeve can be attached to the inner side wall of the cylinder arranged outside the cylinder in a sleeving mode to conduct rotary boring and can also conduct movable boring in the length direction of the cylinder, the machining quality is good, and the machining efficiency is high.

Description

technical field [0001] The invention relates to the technical field of boring bars, in particular to a boring bar for deep hole machining. Background technique [0002] A boring machine is mainly a machine tool that uses a boring tool to bore holes on a workpiece. Usually, the rotation of the boring tool is the main motion, and the movement of the boring tool or the workpiece is the feed motion. Its machining accuracy and surface quality are higher than those of a drilling machine. The boring machine is the main equipment for processing large box parts. [0003] High-precision boring is an important hole finishing method. For deep holes inside large components, such as cylinder bores, etc., in the existing processing methods, ultra-long overhang tools are often used for boring processing, and the boring bar is in the overhang. It is very easy to cause insufficient rigidity of the boring bar, cause vibration, and lead to the decline of machining accuracy, which greatly rest...
