Description

Technical Field

[0001] The utility model relates to precision processing equipment and a tool used therefor, in particular to a deep hole reamer. Background Art

[0002] Reamer is one of the commonly used hole processing tools, used for further processing inside the hole. In some cases, when the reamer is used for deep hole processing, since the external coolant cannot enter the deep hole in time, a large amount of heat is generated between the tool and the workpiece, affecting the deep hole reamer processing quality. At the same time, the reamer life is shortened due to the influence of high temperature.

[0003] Therefore, it is necessary to provide a deep hole reamer to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a deep hole reamer.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A deep hole reamer includes a shank connected to a cutter body extension column, a reamer cutter body is provided at the end of the cutter body extension column, a deep hole coolant inflow hole is opened on the shank, the deep hole coolant inflow hole simultaneously passes through the cutter body extension column and is connected to a branch channel for dispersive coolant inflow of the reamer cutter body;

[0007] The dispersed coolant inflow branch channel includes a vertical connecting branch channel, and the vertical connecting branch channel is connected to the outward dispersed flow branch channel to form a deep hole reamer structure with high-efficiency deep hole cooling.

[0008] Furthermore, there are a number of outward diverging branch channels, which are connected to the side wall of the reamer body in an outward expanding manner with the vertical connecting branch channel as the center reference.

[0009] Furthermore, a plug is provided on the vertical connecting branch channel.

[0010] Furthermore, a tapered cone is provided at the connection between the extension column of the tool body and the tool handle.
