Problems solved by technology

The reamer is used to ream the drilled (or reamed) hole on the workpiece, mainly to improve the machining accuracy of the hole and reduce its surface roughness. It is a tool for finishing and semi-finishing the hole , the machining allowance is generally very small, the existing reamer will wear after a period of processing, and the diameter of the reamer itself becomes smaller, so that the processed hole does not meet the design requirements

Abstract

The invention discloses a welded adjustable reamer. The welded adjustable reamer comprises a reamer bar, a reamer bit and a water cooling hole, wherein the reamer bit is arranged on the front end of the reamer bar; the water cooling hole is coaxially arranged in the middle of the reamer bar; the reamer bit also comprises cutting edges and chip grooves; the cutting edges are arranged around the reamer bit at equal intervals; each chip groove is arranged between every two adjacent cutting edges. Through the structure, the welded adjustable reamer provided by the invention has the advantages that the reliability performance is high, the structure is compact, the radius of the reamer is compensable, the water-cooling temperature reduction is realized, the reamer machining speed is high, the service life is long and adaptability is good, meanwhile, the welded adjustable reamer has broad market prospect in the machining market.

Description

Technical field [0001] The invention relates to the field of reamers, in particular to a welding adjustable reamer. Background technique [0002] The reamer is a rotary tool with one or more teeth to cut the thin metal layer on the processed surface of the hole. The hole processed by the reamer can obtain precise size and shape. The reamer is used to ream the drilled (or reamed) hole on the workpiece, mainly to improve the machining accuracy of the hole and reduce the roughness of its surface. It is a tool for the finishing and semi-finishing of the hole , The machining allowance is generally very small, the existing reamer will wear out after a period of processing, and the diameter of the reamer itself becomes smaller, so that the processed hole does not meet the design requirements. Summary of the invention [0003] The main technical problem solved by the present invention is to provide a welding adjustable reamer. By setting adjustable screws and taper holes, the diameter o...
