Abstract
The utility model discloses a diamond reamer for machining multi-step holes. The diamond reamer comprises a reamer handle. At least two cutting portions with rotation radius increasing gradually are arranged at the front end of the reamer handle from front to back. The cutting portions and the reamer handle are arranged coaxially. Two cutting heads are symmetrically arranged at the front end of each cutting portion. Each cutting portion is provided with eight sections. The cutting heads on a third section, a fourth section and a fifth section of the cutting portion from front to back are of an integral structure, and the cutting heads on a sixth section and a seventh section of the cutting portion from front to back are of an integral structure. The diamond reamer is novel in design, simple in structure, easy to machine and manufacture, convenient and quick to assemble and disassemble, capable of molding the multi-step holes once, high in machining efficiency, high in accuracy and low in rejection rate.
Description
Technical field
The utility model belongs to machining manufacturing technology field, relates in particular to a kind of diamond reamer of processing the multi-ladder hole.
Background technology
On some workpiece of processing during the shoulder hole of a plurality of steps, the processing method that adopts just is to use and many reamer is processed several times at present, and not only efficient is low, and need repeatedly clamp and process, and is easy to occur mismachining tolerance, causes percent defective too high.
The utility model content
The utility model is in order to solve weak point of the prior art, and the diamond reamer in a kind of working (machining) efficiency height, processing multi-ladder hole that precision is high is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the diamond reamer in processing multi-ladder hole, comprise handle of a knife, described handle of a knife front end is provided with the cutting tip that at least two sections radius of gyration increase one by one from front to back successively, cutting tip is arranged with two cutter heads respectively with the coaxial setting of handle of a knife, the front end of every section cutting tip.
Described cutting tip is provided with eight sections, cutting tip from front to back third and fourth, the cutter head on five sections is structure as a whole, the cutter head on from front to back the 6th, seven section of cutting tip is structure as a whole.
The material of described handle of a knife is carbide alloy, and the material of cutter head is diamond.
Adopt technique scheme, have following technique effect:
1, the cutter head on the different radius of gyration cutting tips is processed the hole in corresponding aperture respectively, and can carry out chamfering, thereby disposable with shoulder hole machine-shaping.
2, cutting tip is provided with eight sections shoulder holes that are used for eight steps of processing, because third and fourth, the cutting tip axial length of five sections and 6,7 sections is shorter, therefore with third and fourth, cutter head on five sections and the 6th, seven section is structure as a whole, so just the shoulder hole with workpiece to be machined is corresponding.Each cutter head is used for processing external diameter and the chamfering of different shoulder holes.
3, handle of a knife is the carbide alloy material, and shock resistance is good, and rigidity is strong; Cutter head is the diamond material, has high rigidity and high-wearing feature.
The utility model modern design, simple in structure, be easy to processing and manufacturing, easy to loading and unloading, quick, can be with the disposable machine-shaping of shoulder hole, the working (machining) efficiency height, the precision height, percent defective is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the diamond reamer in processing multi-ladder of the present utility model hole, comprise handle of a knife 1, handle of a knife 1 front end is provided with the cutting tip 2 that eight sections radius of gyration increase one by one from front to back successively, every section cutting tip 2 all with handle of a knife 1 coaxial setting, the front end of every section cutting tip 2 is arranged with two cutter heads 3 respectively.Eight sections cutting tips 2 from front to back third and fourth, the cutter head 3 on five sections is structure as a whole, the cutter head 3 on from front to back the 6th, seven section of eight sections cutting tips 2 is structure as a whole.The material of handle of a knife 1 is carbide alloy, and the material of cutter head 3 is diamond.
In use, the cutter head 3 on the different radius of gyration cutting tips 2 is processed the hole in corresponding aperture respectively, and can carry out chamfering, thereby disposable with shoulder hole machine-shaping, the working (machining) efficiency height, and the precision height, percent defective is low.
