Description

A kind of cut off adds inner chamfer to be integrally formed cutter

Technical field

The utility model relates to cutting tool for CNC machine technical fields, and especially a kind of cutting plus inner chamfer are integrally formed knife Tool.

Background technique

Numerically-controlled machine tool is a kind of high-precision, efficient automated machine tool, and cutter is a kind of important portion in numerically-controlled machine tool Part.Conventional tool used in numerical control processing includes knife handle and cutter head, and cutter head is set to one end of knife handle and is wholely set with knife handle, Blade is provided on cutter head, and big multicutter is for independent process, such as cutoff tool, billmpse tool, boring cutter etc., In When processing pipe part, including the processes such as cutting, Che Ping, chamfering, it needs to process automatically by numerical control programming and cooperates tool changing frame Withdrawing tool changing again, while the processing that subsequent processing is carried out to knife is calibrated again.The time of operation needs in this way is longer, and machinery comes The work that reverses can all wear lathe, service life of equipment be influenced, if can save the process of tool changing, it will greatly improve Production efficiency.

Summary of the invention

The utility model purpose of design is: needing frequent tool changing in view of the processing of existing numerically-controlled machine tool, influences processing efficiency Problem, we, which design, proposes that a kind of cutting adds inner chamfer to be integrally formed cutter, and grooving cutter and chamfering tool are combined into one, are not required to Tool changing meets the needs of to numerically-controlled machine tool highly-efficient processing, also improves processing efficiency and yield.

To achieve the above objectives, the present invention adopts the following technical solutions:

A kind of cut off adds inner chamfer to be integrally formed cutter, knife handle and cutter head including integrally connected.

Linkage section between the cutter head and the knife handle open up it is fluted, and with the knife handle side be equipped with transition chamfering, The linkage section and the cutter head are also equipped with chamfering, and the cutter head, linkage section and knife upper end face and lower end surface flush, described Cutter head upper surface is the rake face of cutoff tool, and the facade of cutter head is the flank of cutoff tool, the cutter head and the connection Section lower end offers ramp down angle, makes the facade of cutter head in isosceles trapezoid, and point of a knife remains with a fillet, and the cutter head facade is in The trapezoidal bottom edge of waist is the cutting edge of cutoff tool, and waist is the cutting edge of chamfer cutter.

Further, the ramp down overturning angle angular range is 30-60 °.

Further, at an angle, this angular range is 75- for the upper surface of the facade of the cutter head and the cutter head 85°。

The cutting for implementing the utility model adds inner chamfer to be integrally formed cutter, has the advantages that

The cutting, which adds inner chamfer to be integrally formed cutter integrated design, cutoff tool and chamfer cutter, does not need heavy programming Code and part coordinate is repeated to calibrate, for one for cutting off, the two is used for chamfering, greatly accelerates the processing of numerically-controlled machine tool Efficiency and yield is improved, is conducive to promote and apply.

Detailed description of the invention

Wherein, 1- knife handle, 11- transition chamfering, 2- linkage section, 21- groove, 22- ramp down angle, 3- cutter head, 31- point of a knife, 32- The cutting edge of chamfer cutter, the cutting edge of 33- cutoff tool.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

As shown in Figs 1-4, the utility model proposes a kind of cutting add inner chamfer to be integrally formed cutter, including integrally connected Knife handle 1 and cutter head 3.

Linkage section 2 between the cutter head 3 and the knife handle 1 opens up fluted 21, and is equipped with transition with 1 side of knife handle Chamfering 11, the linkage section 2 are also equipped with chamfering, the cutter head 3, linkage section 2 and 1 upper surface of knife handle and lower end with the cutter head 3 Face flushes, and 3 upper surface of cutter head is the rake face of cutoff tool, and the facade of cutter head 3 is the flank of cutoff tool, described Cutter head 3 and 2 lower end of linkage section offer ramp down angle 22, make the facade of cutter head 3 in isosceles trapezoid, and point of a knife 31 remains with a circle Angle, the bottom edge of the be in isosceles trapezoid of facade of the cutter head 3 are the cutting edge 33 of cutoff tool, and waist is the cutting edge 32 of chamfer cutter.

Further embodiment is that the range of tilt angles at the ramp down angle 22 is 45 °.

Further embodiment is, the upper surface of the facade of the cutter head 3 and the cutter head 3 at an angle, this angle Spending range is 80 °.
