Embodiment Construction

[0010] The invention discloses a tool for boring and reaming, which comprises a tapered shank, a tool bar, a sleeve reamer and a boring tool; the front end of the tool bar is provided with a boring tool installation hole, and the boring tool is installed on the On the hole, a part protrudes from the boring tool installation hole; the sleeve reamer is detachably socketed on the cutter bar; the sleeve reamer is in clearance fit with the cutter bar, and an adjusting screw is also included; The adjusting screw is a hexagon socket head cap screw. A fastening screw is also included; the fastening screw is an inner hexagonal screw.

[0011] The above-mentioned embodiments only express several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvemen...

Abstract

A tool for boring and reaming comprises a taper shank, a tool bar, a shell reamer and a boring tool. A boring tool installation hole is formed in the front end of the tool bar. The boring tool is installed on the boring tool installation hole, and a part of the boring tool extends out of the boring tool installation hole. The tool bar is detachably sleeved with the shell reamer. The shell reamer is in clearance fit with the tool bar. The tool further comprises an adjusting screw which is an internal hexagonal screw. According to the tool, on the basis of the pore size of a hole to be machined, the extending length of the boring tool can be flexibly adjusted, the shell reamer can be replaced with another one to adapt to changes of the pore size of the hole to be machined, and the purpose that fewer taper shanks and boring bars are arranged to adapt to the large pore size change range is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing metal cutting, in particular to a tool for boring and reaming that can be adjusted according to the diameter of the machining hole. Background technique [0002] As a commonly used hole processing tool, reamer is widely used in machinery manufacturing and industrial production. Existing reamers have one or more cutter teeth for removing the thin metal layer on the machined surface of the hole. Holes are reamed to exact size and shape. The reamer is used to ream the hole that has been drilled (or reamed) 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. [0003] However, when reaming, if the axis of the previously drilled hole is deviated, the reaming will also be deviated along the drilled hole, which greatly reduces t...
