Description

Composite reamer

Technical Field

The utility model relates to a machining cutter field, concretely relates to compound reamer.

Background

Reamers are commonly used reaming or hole repairing tools, are used more in finish machining of holes, and mainly aim at improving machining precision and reducing surface roughness. Traditional reamer generally comprises cutter body and cutting portion, and outer cold type processing mode adopts outer cold type processing mostly, and the cutter body surface all is glossy cylinder and constitutes and lead to cutter body rigidity great, and the weak point that the processing mode of this type of reamer exists lies in: the surface smoothness of the workpiece is poor due to insufficient cooling at the cutting edge; the chip removal effect is not ideal, and the service life of the reamer is further reduced; the cutter body rigidity is great and can make the cutter body unstable and skew former guiding hole when processing thereby influence the machining precision.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the composite reamer is provided, and a central internal cooling type processing method is adopted, so that the cooling effect at the cutting edge is enhanced, and the surface roughness of a workpiece is reduced; the chip removal effect is improved, so that the service life of the reamer is prolonged; the surface of the cutter body is provided with the slow annular groove, so that the rigidity of the cutter body is reduced, and the original guide hole can be machined during machining, so that the machining precision is improved.

In order to achieve the above object, the present invention provides the following technical solutions:

the utility model provides a composite reamer, includes stalk portion, neck, head and water-cooling through-hole, the stalk portion top is equipped with connecting portion, the neck surface is equipped with the ring channel, install the blade on the head edge circumferencial direction, just the terminal surface is equipped with out water chip groove before the head, stalk portion central point is located to the water-cooling through-hole, just the water-cooling through-hole runs through to the head from the stalk portion.

Preferably, the handle and the neck are both cylindrical, the handle diameter is greater than the neck diameter, and the handle, the neck and the head are coaxially arranged.

Preferably, the number of the annular grooves is a plurality of the annular grooves, and the annular grooves are uniformly distributed on the circumferential surface of the neck.

Preferably, the number of the blades is several, and the blades are distributed in an array along the circumferential direction of the head.

Preferably, the play water chip groove specifically is a plurality of, the interval set up in between the blade, just go out the water chip groove with the water-cooling through-hole is on a plane.

The utility model has the advantages that: a composite reamer adopts a central internal cooling type processing method, can enhance the cooling effect at a cutting edge and reduce the surface roughness of a workpiece; the chip removal effect is improved, so that the service life of the reamer is prolonged; the surface of the cutter body is provided with the slow annular groove, so that the rigidity of the cutter body is reduced, and the original guide hole can be machined during machining, so that the machining precision is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 2, the composite reamer comprises a handle 1, a neck 2, a head 3 and a water-cooling through hole 8, wherein a connecting part 4 is arranged at the top end of the handle 1, an annular groove 5 is arranged on the surface of the neck 2, a blade 6 is arranged on the head 3 along the circumferential direction, a water-discharging chip groove 7 is arranged on the front end surface of the head 3, the water-cooling through hole 8 is arranged at the central position of the handle 1, and the water-cooling through hole 8 penetrates from the handle 1 to the head 3; the connecting part 4 is used for connecting with a processing machine tool.

The handle part 1 and the neck part 2 are both cylinders, the diameter of the handle part 1 is larger than that of the neck part 2, and the handle part 1, the neck part 2 and the head part 3 are coaxially arranged.

The annular grooves 5 are uniformly distributed on the circumferential surface of the neck 2; the annular groove 5 is used for reducing the rigidity of the cutter body so that the cutter body does not deviate in position during machining.

The blades 6 are specifically a plurality of blades and are distributed in an array along the circumferential direction of the head 3.

The water outlet chip grooves 7 are arranged among the blades 6 at intervals, and the water outlet chip grooves 7 and the water cooling through holes 8 are on the same plane; go out water chip groove 7 and be used for discharging the sweeps that produces during processing, water-cooling through-hole 8 can realize processing the cooling effect of cutting edge department and can wash away the sweeps in the water chip groove 7.

The utility model discloses a theory of operation does: firstly, the connecting part 4 is installed on a machining machine tool, the machine tool is started to drive the reamer to work, cooling liquid in the water cooling through hole 8 flows out simultaneously in the machining process, on one hand, the cutting edge part realizes the quick cooling effect due to the cooling liquid, on the other hand, waste chips accumulated in the water outlet chip removal groove 7 are washed away due to the flowing of the cooling liquid, so that the good chip removal effect is realized, and the service life of the cutter can be prolonged.
