Problems solved by technology

[0005] To this end, the present invention provides a composite material hole machining staggered edge drill reamer, the chips generated by the secondary cutting edge and the arc edge on the metal processing surface are diverted to the chip guide groove through the chip splitting groove, and the chips of the main cutting edge go to the chip guide groove. The chip guide groove guides the flow to the chip discharge groove, the roller fits the metal surface in the hole, the roller rolls the metal surface in the hole, presses the protruding part of the surface into the concave part, and processes the hole into a smooth surface to solve the problem. The problem of poor mirror processing effect

Abstract

The invention belongs to the technical field of industrial tools, and particularly relates to a staggered edge drill reamer for composite hole machining. The staggered edge drill reamer comprises a drill rod, a tail handle and an adjusting device. According to the technical scheme, the adjusting device is arranged at the right end of the drill rod, and comprises a shell I, and a parallel bearing is fixedly mounted on the left side of the shell I; a shell II is fixedly installed on the left side of the parallel bearing, and a spacing ring is fixedly installed on the right side of the shell I; and the tail handle is fixedly installed on the right side of the spacing ring, and a mandrel is fixedly arranged on the left side of the tail handle, and installed on the inner walls of the shell I and the shell II. The invention has the beneficial effects that chips generated on a metal processing surface through ab auxiliary cutting edge and an arc edge are guided to a chip guide groove througha chip dividing groove, and the chips of a main cutting edge are guided to a chip groove through the chip guide groove; a roller is attached to the metal surface in the hole, and the metal surface inthe hole is rolled through the roller, so that the protrusion part of the surface is pressed into the concave part; and the smooth surface is machined in the hole, and the super mirror machining and polishing effects are achieved.

Description

technical field [0001] The invention relates to the technical field of industrial cutting tools, in particular to a drilling and reaming tool with staggered edges for machining holes made of composite materials. Background technique [0002] The drill reamer has one or more cutter teeth, which are used to remove the thin metal layer on the machined surface of the hole. The hole processed by the reamer can obtain accurate size and shape. The reamer is used to ream the drilled workpiece The hole after cutting or reaming is mainly to improve the machining accuracy of the hole and reduce the roughness of its surface. It is a tool for finishing and semi-finishing the hole. The machining allowance is generally small, and it is used to process the cylinder. Reamers for shaped holes are more commonly used. [0003] The existing technology has the following disadvantages: the existing tools can only be used for fine cutting of non-ferrous metals and non-metals, and are prone to defe...
