Abstract
The invention discloses a kind of drilling dedicated tool and its application methods, belong to field of machining.Cutter body includes cutting parts, retaining part, escape groove, step positioning surface, it is used cooperatively with special washer and angle head, special washer is inserted in from cutter holding position first when replacing drilling dedicated tool, one side end face of washer is bonded with step positioning surface, then cutter and special washer are put into togerther angle head retaining part, guarantee that another side end face of washer is bonded with angle head positioning surface, locks angle head, complete the clamping of cutter.Drilling dedicated tool provided by the present invention and its application method, it may be implemented to replace dedicated tool in the case where not dismantling angle head, reduce disassembly angle head, process long using side tool instrument measurement knife and that cutter is installed on angle head, both cutter clamping efficiency had been improved, the error that angle head relocates on machine tool chief axis is reduced again, while also ensuring the accurate active length of cutter.
Description
Technical field
The present invention relates to a kind of designs of dedicated tool, clamping and application method, and in particular to a kind of drilling dedicated tool and
Its application method.
Background technique
The clamping of today's numerical control cutter has precise measurement toolsmith by dedicated survey knife instrumentation, dedicated survey knife instrument
Make length, the advantages that clamping precision is high, but not only operating process is cumbersome, the clamping time is long for this mode, and can not be in number
It is carried out on control process equipment.When bored, expanded using angle head clamping cutter, ream processing when, each tool changing all must be by angle
Degree head is unloaded from machine tool chief axis together with cutter, is sent to special field and is carried out using knife instrument is surveyed to knife, dress knife, then will
The angle head foldback for installing cutter returns numerically-controlled machine tool, and the clamping position of angle head is relocated by operator.
If considering the clamping cutter in the case where machine tool chief axis does not dismantle angle head, the manual clamping of operator is needed.
Existing NC cutting tool is largely cylinder staight shank cutter, and without using knife instrument is surveyed, operator by grasping manually
It is larger to will lead to cutter clamping error in length.For needing through angle head drilling blind hole and controlling the part of hole depth, process
Depth just cannot effectively guarantee.
Therefore, design one kind can by operator voluntarily on angle head clamping simultaneously and can guarantee that active length is being processed
Stablizing constant cutter in the process is necessary.
Summary of the invention
The present invention is directed to the above problem in the prior art, devises a kind of drilling dedicated tool, the drilling dedicated tool
Can be mounted on angle head by operator, realize cutter accurate positionin and secured clamping, while can guarantee that cutter is accurate again
Active length.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of drilling dedicated tool, including cutter body and washer, it is characterised in that: the cutter body be divided into cutting parts and
Retaining part, the diameter of the cutting parts are greater than the diameter of retaining part, are equipped with and keep away between cutting parts and retaining part
Allow slot, the height at base angle is less than the profile height of escape groove, the contact surface of the cutting parts and escape groove in the escape groove
Upper formation step end face, the washer cover the outside in escape groove and retaining part.
Further, the step end face is circular plane, and flatness is less than 0.01mm, with tool rotating shaft line
Verticality be less than 0.01mm.
Further, the diameter of the retaining part is 2mm or more smaller than the diameter of cutting parts.
Further, the length dimension tolerance of the cutting parts is less than ± 0.1mm.
Further, the internal diameter of the washer is 0.1mm ~ 0.2mm bigger than the diameter of retaining part, and the thickness of washer, which is greater than, to be kept away
Allow the width of slot, the thickness tolerance of washer is less than ± 0.1mm；The both ends of the surface of washer are circular positioning surface, flatness
< 0.01mm.
A kind of application method of drilling dedicated tool, which comprises the steps of:
Washer is inserted in from the one end at cutter holding position, is bonded one side end face of washer with step end face by step 1；
Cutter and washer are put into togerther the retaining part of angle head by step 2, guarantee that another side end face of washer and elbow position
Face paste is closed；
Step 3 locks angle head, completes cutter clamping.
The technical program has the beneficial effect that:
1, in the present invention, the cutter body of the drilling dedicated tool includes cutting parts and retaining part, the cutting parts
Diameter be greater than retaining part diameter, escape groove, the base angle of the escape groove are set between cutting parts and retaining part
Height is less than the profile height of escape groove.Therefore, for the step end face formed between cutting parts and escape groove, it is located at
Area other than inside diameter of gasket φ D is smooth flat, and there is no any fillet, chamfering or other protrusion structures.Institute
With the end face of washer can be bonded the end face of cutting parts completely, realize the accurate positionin between cutter body and washer.
2, in the present invention, since washer all covers escape groove, cutter and angle can be realized by the other end of washer
Spend the axially position between head.Therefore, it will not occur directly to contact between escape groove and the positioning surface of angle head, eliminate angle
The stuck risk in escape groove in end of circlip, is not in be difficult to the phenomenon that dismantling cutter in head.
3, in the present invention, the other end of washer need to only be abutted the positioning surface of angle head by operator, and system can be realized
The accurate positionin of hole professional knife does not need together to tear angle head connection cutter open when the cutter for the same size that needs to change the outfit
Under be sent to other places using survey knife instrument to knife.Therefore, clamping process is simple, shortens the clamping time.
