Description
Technical field
The utility model relates to deep-hole machining tool, especially a kind of two-stage sword reamer.
Background technology
Compressor impeller is the vital part in booster, and its endoporus quality quality, directly has influence on booster extent of vibration and life-span.The endoporus of compressor impeller belongs to Fine and Deep Hole, more difficult processing, easily causes the degree of consistency of product poor.
Adopt common single-stage sword reamer processing Fine and Deep Hole, precision is difficult to reach requirement, if work in-process uses bottoming reamer instead, then need to recalibrate, complicated operation affects working (machining) efficiency.
Bottoming reamer is because its material is carbide alloy in addition, and cost is also higher.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of with cutting and the cutter of extruded hole function, solve the process issues of Fine and Deep Hole, can guarantee that compressor impeller endoporus ten thousand uniformity are within the scope of 0.005mm, working (machining) efficiency is also improved while improve machining accuracy, and can be cost-saving.The technical solution adopted in the utility model is:
With cutting and the cutter of extruded hole function, comprising cutter head and being connected to the handle of a knife of cutter head tail end, cutter head and handle of a knife coaxial;
The anterior cylindrical of cutter head is processed with after going to guiding cutting edge, main cutting edge successively, essence is cut and sword is combined in extruding; Guiding cutting edge and main cutting edge connect together; Main cutting edge and essence are cut and are extruded to combine between sword and be provided with First Transition groove; Essence cuts the external diameter 0.002mm ~ 0.01mm larger than the external diameter of main cutting edge combining sword with extruding.
Further, the tail end end face of cutter head has one section of linkage section, the front end surface of handle of a knife is provided with connecting hole, cutter head linkage section is with handle of a knife connecting hole interference fit and weld.
Further, essence cutting is combined sword with extruding and is comprised smart cutting edge and extruded segment, is provided with the second lead-over groove between smart cutting edge and extruded segment.
Further, the chamfering of cutter head guiding cutting edge is 3 ~ 5 degree.
Preferably, the material of handle of a knife is steel alloy.
The utility model has the advantage of: this cutter, without the need to twice school cutter, reduces the repeatable accuracy requirement to equipment, decreases equipment investment, reduce process time simultaneously, reduce production cost.Handle of a knife adopts lower-cost material, can save cutter holistic cost.
Accompanying drawing explanation
Fig. 1 is structure of the present utility model composition schematic diagram.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
Band that the utility model proposes cuts and the cutter of extruded hole function, as shown in Figure 1, comprises cutter head 1 and is connected to the handle of a knife 2 of cutter head 1 tail end, cutter head 1 and handle of a knife 2 coaxial; The material of handle of a knife 2 is common steel alloy and through quenching, can cost saving, and processability is good, not fragile.Cutter head 1 adopts carbide alloy as in the prior art, provides enough cutting hardness.
The anterior cylindrical of cutter head 1 is processed with after going to guiding cutting edge 101, main cutting edge 102 successively, essence is cut and sword 103 is combined in extruding; Wherein the chamfering of guiding cutting edge 101 is 3 ~ 5 degree, is the cutting targeting part of cutter; Main cutting edge 102 and essence are cut and are extruded to combine between sword 103 and be provided with First Transition groove 104.
Guiding cutting edge 101 and main cutting edge 102 connect together, can as rough edge, and essence is below cut and combined sword 103 as retrofit blade with extruding.
Essence cutting is combined sword 103 with extruding and is comprised smart cutting edge 1031 and extruded segment 1032, is provided with the second lead-over groove 1033 between smart cutting edge 1031 and extruded segment 1032.
Essence cuts the external diameter 0.002mm ~ 0.01mm larger than the external diameter of main cutting edge 102 combining sword 103 with extruding; In deep hole machining process, first be that guiding cutting edge 101 carries out guiding and cuts, then main cutting edge 102 slightly cuts with scissors, and last essence is cut and combined sword 103 and carry out retrofit with extruding, as long as whole process just can continually complete after once school cutter, improve working (machining) efficiency.
The tail end end face of cutter head 1 has one section of linkage section 105, the front end surface of handle of a knife 2 is provided with connecting hole 201, welded by the interference fit of cutter head 1 linkage section 105 and handle of a knife 2 connecting hole 201, realize the connection of cutter head 1 and handle of a knife 2.
