The invention relates to the related technical field of boring cutters, in particular to an inner-hole-adjustable boring cutter. The defects that in the prior art, users cannot drill holes in trapezoidal materials conveniently, the mounting manner between a boring cutter and drilling equipment is quite complex, and consequently the overall use performance of the boring cutter is poor are overcome.The boring cutter comprises a first limiting ring, movable rods and a fixed rod. An outer boring body is welded to the tail end of the first limiting ring, an inner boring body is welded to the tailend of a second limiting ring, limiting sleeves are welded to the outer side of the top end of the first limiting ring, the movable rods are welded to the outer side of the tail end of the second limiting ring, an inner boring handle is mounted on the outer wall of an outer boring handle, the fixed rod is mounted in the outer boring handle, clamping rings are welded to the outer wall of the fixedrod and the outer wall of the outer boring handle, threaded rods communicate with the interiors of the clamping rings, baffles are welded to the upper portion of the inner wall of the outer boring body, rotating shafts are welded to the lower portion of the inner wall of the outer boring body, and blocking plates are mounted on the outer walls of the rotating shafts.
Description
technical field [0001] The invention relates to the related technical field of boring cutters, in particular to a boring cutter with an adjustable inner hole. Background technique [0002] Boring tool is a kind of boring tool, generally with round handle, and there are also square tool bars for larger workpieces. The most commonly used occasions are inner hole processing, reaming, profiling, etc., with one or two cutting parts, special A tool for roughing, semi-finishing or finishing an existing hole. Boring tools can be used on boring machines, lathes or milling machines. [0003] However, the currently used boring tool is not convenient for users to drill trapezoidal materials, and the installation method with the drilling equipment is relatively complicated, which makes the overall performance of the boring tool poor. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the currently used boring tool in the prior art is n...
