Specific embodiment

This utility model is described in further detail with reference to preferred embodiment of the present utility model, but this practicality New embodiment not limited to this.

The explanation of nouns of lathe cutter related angle is as follows：

1st, anterior diastema angle

It is down anterior diastema angle to the tilted angle of knife from knife nose, because there is under anterior diastema angle, work surface and point of a knife formation One space, makes shear action concentrate on knife nose.If this angle is too little, cutter will be rubbed on the surface, and produce matsurface, angle Too big, cutter is susceptible to tremble, and makes the knife nose fragmentation cannot light system.Load onto the lathe tool mill anterior diastema angle with hilt in inclination When, hilt angle of inclination need to be considered.The anterior diastema angle is clearance angle γ for 7 ° in embodiment 1.

2nd, side clearance angle

Knife side autotomy chamfered edge to the tilted angle of knife be side clearance angle.Side clearance angle makes work object plane and knife side shape Make shear action concentrate on cutting edge into a space and improve stock-removing efficiency.Side clearance angle described in embodiment 1 is equal to clearance angle γ For 7 °.

3rd, back bevel angles

It is back bevel angles from knife top surface from knife nose to the inclined angle of handle of a knife.This angle is mainly in guiding chip removal and the row of reduction Bits resistance.In embodiment 1 back bevel angles be angle of inclination between the second cutting edge 2 and chip area 5 be 12 °, the termination of chip area Radius is 12 millimeters.

4th, nose radius

The edge of a knife arc radius of blade peak.The big intensity of nose radius is big, for big cutting depth, but easily produces Dither, it is 3 millimeters that the nose radius in embodiment 1 is cylindrical point of a knife R.

5th, bias

Incline from knife top surface chamfered edge of autotomying to another side, this inclined plane and horizontal plane angulation are bias.This angle It is the angle for making chip depart from working substance, makes chip removal easily and obtain effective turning.

6th, knife-ended angle

The knife-edge leading end angle vertical with handle of a knife.The holding knife-edge leading end that act as of this angle has a gap to keep away with workpiece 13 Exempt from blade to rub or abrade machined surface with workpiece 13.

7th, cutting edge angle

The knife-edge leading end angle vertical with handle of a knife, which act as changing the thickness for cutting layer.Cutting edge angle can also change car simultaneously Knife Impact direction, reduces feed resistance, increases cutter life, therefore when general rough turn, preferably using the lathe tool that cutting edge angle is larger, with Feed resistance is reduced, increases cutting speed.

Embodiment 1：

With reference to shown in accompanying drawing 1-5, a kind of multi-functional lathe tool, the lathe tool are in irregular pentagon, and including cylindrical point of a knife 4th, and the cylindrical point of a knife 4 connection the first cutting edge 1 and the first cutting edge 1 being sequentially connected, the second cutting edge 2 and the 3rd Cutting edge 3, is provided with a chip area 5 on the lathe tool, the length direction of the chip area 5 is flat with second cutting edge 2 Row is arranged and port is connected with the 3rd cutting edge 3, and first cutting edge 1, the second cutting edge 2 and the 3rd cutting edge 3 are equal It is correspondingly arranged on identical clearance angle γ 10 and clearance angle γ 10 is 7 °.

Preferably, the cylindrical point of a knife 4 is that circular arc is arranged and R is 3 millimeters.

Preferably, 5 port arc radius of the chip area are 10-12 millimeters.

Preferably, the first angle α 7 between first cutting edge 1 and adjacent free margins is 35 ° -75 °.

Preferably, the second angle β 8 between first cutting edge 1 and the second cutting edge 2 is 5 ° -30 °.

Preferably, the 3rd angle δ 9 between second cutting edge 2 and the 3rd cutting edge 3 is 5 ° -30 °.

Preferably, the lathe tool also include for install the lathe tool screw hole 6 and the screw hole 6 be counter sink and Aperture d11 is 5-8 millimeters.

Preferably, the lathe tool material be carbon tool steel, alloy tool steel, high-speed steel, hard alloy, in diamond Any one.

Further, the joint face between second cutting edge and chip area is obliquely installed, and its object is to using This utility model can carry out automatic curled to metal fillings when carrying out endoporus turning, and in metal fillings after crimping 360 ° -720 ° Automatically rupture in the presence of itself internal stress, drop, prevent from causing the unexpected of 13 surface of workpiece to scratch because of the delay of metal fillings.

Operation principle is installation method：

The present embodiment is illustrated by taking turning as an example.

Installation steps：Screw hole of the present utility model is directed at the installing hole on knife rest 12 by the first step, it is ensured that this practicality is new What type was complete is connected in the Cutting tool installation manner groove of knife rest 12, and here is worth illustratively, as this utility model is multiplex Way lathe tool, is provided with the groove for clamping cutter corner on knife rest 12, prevent when carrying out big cutting output and processing, due to stress it is many Cause greatly cutter that slight deflection occurs, affect machining accuracy, increase mismachining tolerance.Carried out with matching screw after Cutting tool installation manner is good Fastening, fastening tool determine force square for 50NM-60 NM using torque wrench is determined；Second step, by the knife for processing excircles Sword circular arc R is carried out to knife with workpiece 13, determines cutting output；3rd step, manual feed are cut.

The present embodiment direction of feed be according to carried out shown in Fig. 1 from right to left progressively feed cutting, carrying out cylindrical turning Under state, the corresponding anterior diastema angle of the present embodiment corresponds to clearance angle γ for 7 °；It is clearance angle γ that side clearance angle is anterior diastema angle For 7 °；Back bevel angles is 12 °；Bias correspond to α for 40 °；Knife-ended angle corresponds to the second angle β for 15 °；Nose radius is corresponded to R is 3 millimeters；Under above-mentioned angle case by taking turning as an example, workpiece material be No. 45 carbon steel, lathe rotating speed be 1200 turns/ Point, cutting output be 1 millimeter, enter speed for 0.2 mm/second when, workpiece surface roughness can reach Ra1, when speed is entered be During 0.1 mm/second, workpiece surface roughness can reach Ra0.6, and its cutting quality is substantially due to regular turning tool level.

Embodiment 2:

Use to further illustrate multipurpose of the present utility model, on the basis of in conjunction with the embodiments 1 structure, incite somebody to action this , used as during chamfering turning, its corresponding working condition and installation method are as follows for utility model：
