Abstract
The utility model discloses a drilling tool mainly comprises a handle portion and a cutting portion. The cutting portion is provided with a cutting multi-step edge and a chip groove. Stepped hole, chamfer arc and borehole machining tools for workpieces are integrated, machining can be achieved once, time is shortened and production efficiency is improved.
Description
Technical field
The utility model relates to cutter field, is specifically related to a kind of moulding drilling tool.
Background technology
The processing of existing workpiece shoulder hole, is all that boring, reaming, spot-facing complete conventionally, and the method just can be completed by working procedures and multicutter, and cost is high like this, length consuming time, and efficiency is very low.There are at present a lot of occasions need on workpiece, bore notch cuttype irregularly-shaped hole, and use existing hole machining tool cannot meet instructions for use, processing an irregularly-shaped hole conventionally needs several operations, needs the cutter of plurality of specifications to process just can complete, so both complex procedures, cost is also high.By the improvement of cutter structure, develop a kind of cutter and have that to overcome above technical problem imperative simultaneously.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, and a kind of aperture knife tool that has multiple function and concentrate on one is provided.
Realizing the technical solution of the utility model is: a kind of moulding boring bar tool, and described cutter is made up of shank portion and cutting tip, and described cutting tip is made up of tapering and the cutting edge of many steps.
As preferably, described cutting tip is provided with three steps.
As preferably, three described step radiuses dwindle successively, near the step radius maximum of handle of a knife, the step radius minimum at top.
As preferably, described tapering has row and cuts groove, and it is helical form that row cuts groove.
As preferably, described row cuts groove and has two, and front and back are symmetrical mutually.
As preferably, described tapering is outputed after row cuts groove and is formed cutting edge.
The utility model is applicable to process the hole processing of the high step angle of multiple required precisions, easily chip removal, outward appearance fineness can reach and be more than or equal to RA1.6, concentricity can reach 0.02, save tool changing process time, be applicable to produce in enormous quantities, the utility model has solved the too much defect of tool specification, the use function that has increased cutter, has reduced processing cost.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.
Fig. 1 is this practical moulding drilling tool cross-sectional view.
In the accompanying drawings: 1, shank portion; 2, tapering; 3, cutting edge; 4, row cuts groove.
The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment being described with reference to the drawings, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
In description of the present utility model, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, for example, can be mechanical connection or electrical connection, can be also the connection of two element internals, can be to be directly connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
Shown in Fig. 1, a kind of moulding drilling tool, described cutter is made up of shank portion 1 and cutting tip, described cutting tip is made up of the tapering 2 of many steps, cutting tip is provided with three steps, and the radius of three steps dwindles successively, near the step radius maximum of handle of a knife 1, the step radius minimum at top, groove 4 is cut by described tapering 2 rows of having, and the rear formation cutting edge 3 of groove 4 is cut by tapering 2 rows of outputing, and described row cuts groove 4 and has two, front and back are symmetrical mutually, and row cuts groove 4 for helical form.
Generally cutting portion branch High Rotation Speed under the effect of motor, add man-hour at tool operating, cutting tip moves downward in vertical direction until contact the surface of workpiece, now cutter continues to move downward to horizontal movement after certain depth according to the demand of workpiece self, common drilling tool can not disposablely get out the irregularly-shaped hole that radius changes up and down at present, need to repeatedly process getting out the drill bit that changes different size after an aperture, not only waste time and energy, need to prepare extra drill bit, also be not easy to control the degree of depth in aperture, and cutting tip of the present utility model is provided with multiple steps, and the radius of step changes successively, this has just guaranteed once just can process irregularly-shaped hole, cutter also has helicla flute 4 simultaneously, still because can form cutting edge 3 after helicla flute 4 flutings, workpiece is not processed, also because can discharge by helicla flute 4 equally adding the cut part of workpiece in man-hour, otherwise chip unnecessary in cutting process overstocks, can cause damage to workpiece itself, and just not having the problem of this respect after having opened helicla flute 4, the surface of the work after tool sharpening can be very smooth.
The utility model is applicable to process the hole processing of the high step angle of multiple required precisions, easily chip removal, outward appearance fineness can reach and be more than or equal to RA1.6, concentricity can reach 0.02, save tool changing process time, be applicable to produce in enormous quantities, the utility model has solved the too much defect of tool specification, the use function that has increased cutter, has reduced processing cost.
In the description of this description, the description of reference term " embodiment ", " example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present utility model is limited by claim and equivalent thereof.
