The invention relates to a straight reamer with a positioning aid. The straight reamer comprises a body and a shank. The body is provided with an end cutting edge and a plurality of side cutting edges which are linear; flutes are provided among the side cutting edges; the shank is provided with a positioning step; the lower end of the shank is provided with a positioning though hole and a guide through hole; a positioning block is arranged inside the positioning through hole; the positioning through hole is communicated with the guide through hole; a spring cavity is arranged under the guide through hole and communicated with the same; a spring is arranged inside the spring cavity; a push rod is arranged inside the spring cavity; the shank is sleeved with a sleeve and a sleeve cover. The positioning step can be tightly pressed by the sleeve and the sleeve cover; after the push rod is pushed, the push rod pushes the positioning block into the positioning groove, and the sleeve is fixed on a rotating shaft of a machine tool finally; the reamer is avoided slipping during operating; the reamer is simple and reasonable in structure and convenient to mount and demount.
Description
technical field [0001] The invention relates to a straight reamer, in particular to a straight reamer with a positioning aid. Background technique [0002] A variety of reamers are often used in the machining industry. Most reamers are directly clamped by the fixture on the machine tool when the reamer is working. When the reamer is working, the rapid rotation will cause the reamer to slip and affect the processing effect of the reamer. . Contents of the invention [0003] The object of the present invention is to provide a straight reamer with a positioning auxiliary device which has a simple and reasonable structure and prevents slipping. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] A straight reamer with a positioning auxiliary device, comprising a cutter body and a handle, the cutter body is provided with an end face cutting edge and a plurality of side cutting edges, the side cutting edges are straight, and ...
