AI Technical Summary
Technical Problem
Existing boring tools are difficult to eliminate lathe machining errors during installation, resulting in low machining accuracy.
Method used
An adjustable boring bar was designed, which allows for quick adjustment of the boring bar's descent range via an indicator bar and pointer. Combined with a bolt and nut fixing structure, stability is increased, and a laser indicator light enhances the observation effect.
Benefits of technology
It enables rapid adjustment of the boring bar's installation and lowering range, improving the boring bar's installation stability and observation effect, reducing machining errors, and improving machining accuracy.

Abstract
The utility model belongs to the technical field of machining, and particularly relates to an adjustable boring cutter which comprises a cutter bar, and the side wall of the cutter bar is fixedly connected with a pair of fixing plates. A pair of first bolts is in threaded connection with the interior of the fixing plate; a fixing rod is arranged in the fixing plate in a sliding fit mode. The side wall of the fixing rod is in threaded connection with a second bolt. A boring cutter body is arranged in the fixing rod in a sliding fit mode. The second bolt is in contact with the boring cutter body; a sliding groove is formed in the surface of the cutter bar. A pointer is slidably connected into the sliding groove. A plurality of indicating strips are fixedly connected to the outer wall of the cutter bar; the pointer and the indicating strip are correspondingly arranged; and the fixed rod can be quickly fixed by adding an indicating strip and a pointer, so that quick adjustment can be performed through the indicating strip corresponding to the pointer when the descending amplitude of the boring cutter body is adjusted through the sliding groove, and therefore, the inspection effect during adjustment is improved, and the descending amplitude of the boring cutter body is quickly adjusted.
