Abstract
The utility model relates to a reamer belonging to the technical field of machining tools, in particular to a drilling reamer for processing a deep hole. The drilling reamer comprises a reamer handle and a blade positioned at the tail end of the reamer handle, wherein the blade comprises a spiral groove, a blade belt and a drill tip, the blade belt is positioned at the top end of the side surface of the spiral groove, the drill tip is positioned at the tail end of the blade belt, the spiral groove consists of a main spiral groove and an auxiliary spiral groove which are in transitional connection by the blade belt; due to the structure, the drilling reamer can cut into a workpiece conveniently, and the eccentricity is prevented, so that the cutting force is stabilized and optimized in the radial direction, the vibration in the reaming process can be avoided, and the precision and the glossiness of a reaming hole can be ensured.
Description
Technical field
The utility model relates to a kind of reamer, and especially a kind of deep hole machining drilling reamer belongs to the machining tool technical field.
Background technology
Deep hole machining is normally processed than the hole greater than 10 with the diameter in hole the length in hole.Deep hole processing cutter of the prior art, knife bar often are subjected to the restriction in aperture, and diameter is little, and length is big, cause poor rigidity, and intensity is low, easily produce vibration, ripple and tapering during cutting, thereby influence the linearity and the surface roughness of deep hole.And the great majority in these holes are had relatively high expectations to machining accuracy and surface quality, and part machined material self is difficult-to-machine material in addition, therefore bring very big puzzlement for deep hole machining.
Therefore, how to design a kind of novel deep hole processing cutter, become the technical barrier that those skilled in the art need to be resolved hurrily to overcome above-mentioned defective.
The utility model content
The utility model aims to provide a kind of deep hole machining drilling reamer, it has overcome above-mentioned deficiency by special structure design, be beneficial to the incision workpiece and prevent the radially stable optimization of off-centre, cutting force, avoided the vibrations in ream processing, guarantee fraising precision and fineness.Its technical scheme that adopts is as follows:
This deep hole machining drilling reamer mainly comprises: handle of a knife and the blade that is positioned at the handle of a knife end, and wherein, described blade includes helicla flute, land and apex point, and described land is positioned at top, described spiral fluted side, and described apex point is positioned at the end of described land; Described helicla flute is made of main helicla flute and secondary helicla flute, adopts described land transition to connect between described main helicla flute and the secondary helicla flute.
Preferably, described secondary helicla flute is the front top rake angle helicla flute, and it forms secondary land.
Compared with prior art, the utlity model has following advantage:
This product is beneficial to the incision workpiece, prevents off-centre; Secondary spiral fluted participates in cutting, makes the radially stable optimization of cutting force, has avoided the vibrations in ream processing, guarantees fraising precision and fineness.

The A-A cutaway view of Fig. 2: Fig. 1;
Fig. 3: the enlarged drawing of the apex point 5 among Fig. 1.
Symbol description: 2, main helicla flute; 3, secondary helicla flute; 4, land; 5, apex point.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example:
An embodiment of the present utility model is shown in Fig. 1-2, this deep hole machining drilling reamer mainly comprises: handle of a knife and the blade that is positioned at the handle of a knife end, and wherein, blade includes helicla flute, land 4 and apex point 5, land 4 is positioned at top, spiral fluted side, and apex point 5 is positioned at the end of land 4; Wherein helicla flute is made of main helicla flute 2 and secondary helicla flute 3, adopts land 4 transition to connect between main helicla flute 2 and the secondary helicla flute 3.
Preferably, secondary helicla flute 3 is the front top rake angle helicla flute, and it forms secondary land.
Adopt said structure, form special apex point shape, be more conducive to cut workpiece, prevent off-centre as Fig. 3; And secondary spiral fluted participates in cutting, makes the radially stable optimization of cutting force, has avoided the vibrations in ream processing, guarantees fraising precision and fineness.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
