Compared with the prior art, the utility model beneficial effect who has is: effectively strengthen the self guidance performance and the performance of repairing light of reamer, improve the processingquality and the life of reamer, can also adjust beating of reamer through adjustable flange, prevent that the blade of sword tooth from taking place the pump loss, guarantee the integrality of blade.

Drawings

The utility model discloses there is following figure:

FIG. 1 is a schematic view of the present invention;

fig. 2 is a side view of fig. 1.

Detailed Description

As shown in the figure, the PCD composite reamer comprises a reamer handle 1, the tail end of the reamer handle 1 is installed on an adjustable flange 2, the front end of the reamer handle 1 is connected with a reamer body 11, spiral chip removal grooves 12 which are arranged in central symmetry are formed in the circumferential surface of the reamer body 11, the inclination of the chip removal grooves 12 is 5 degrees, a reamer head 13 is arranged at the front end of the reamer body 11, inclined grooves 14 which are communicated with the chip removal grooves 12 and are positioned on the same spiral line are formed in the reamer head 13, each inclined groove 14 is provided with an installation surface and a transition surface which is connected with the front end opening of the chip removal groove 12, the technical effect of effective chip removal can be achieved through the inclined grooves 14 and the chip removal grooves 12, blades 3 are installed on the installation surface, cutter teeth 15 are arranged between every two adjacent inclined grooves 14, the front angle of each cutter tooth 15 is 5-10 degrees, the structure with the large front angle is matched with, in the present embodiment, the rake angle of the cutter teeth 15 is set to 10 °; the peripheral surface of the cutter tooth 15 is distributed with a plurality of teeth 151, each tooth is provided with a cutting edge 1511, in the embodiment, the width of the cutting edge 1511 is 0.2mm, and the back taper amount of the cutting edge 1511 is 1:1000, so that the self-guiding performance and the light-trimming effect of the reamer are effectively enhanced by the structure; the tool body 11 is provided with an annular groove 16 at the rear side of the cutting head 13, which further enhances the chip removal effect.

In the present embodiment, the chipping of the cutting edge of the cutter tooth 15 is 4 to 5 μm, and the surface roughness is not more than ra0.08. The cutting edge of the embodiment is manually passivated in a micro-scale manner by using the oilstone after accurate grinding, so that the phenomena of stress concentration, surface scratch and the like caused by micro-collapse of the cutting edge are reduced, the service life of the reamer is effectively prolonged, and the processing quality of the reamer is effectively improved.

In the present embodiment, the end of the blade 3 protrudes beyond the end of the cutter tooth 15 to achieve better machining effect.

In the present embodiment, the adjustment of the flange 2 is achieved by the following structure: the flange 2 is evenly provided with a plurality of first threaded holes 22 used for connecting fixing screws and second threaded holes 21 used for connecting adjusting threaded screws along the axial direction, and the directions of the first threaded holes 22 and the second threaded holes 21 are opposite.
