Detailed description：
As shown in attached drawing 1- attached drawing 3, the present invention is a kind of engine crankshaft centre bore chamfer machining cutter, and described starts
Machine crankshaft centre bore chamfer machining cutter includes cutter cutter hub 1, and 1 one end of cutter cutter hub is connect with driving motor 2, cutter cutter hub 1
The other end is arranged chamfering tool 3 and deburrer 4, and cutter cutter hub 1 includes cutter hub front end face 5, before deburrer 4 and cutter hub
The structure that the size at a distance from cutter hub front end face 5 of chamfering tool 3 is set greater than apart from size of end face 5, chamfering tool 3
Chamfering tool blade 6 is set as the structure with the angle at an acute angle of crankshaft axis 7, the deburrer blade 8 of deburrer 4
It is set as the structure with the angle at an acute angle of crankshaft axis 7.Above structure is passing through drilling device in engine crankshaft ontology
After processing crankshaft end-face centre bore 13 on 16, effective chamfering 14 can be also processed in crankshaft end-face centre bore 13, then again will
Engine crankshaft ontology 16 is fixed, and control cutter cutter hub 1 is mobile in place, and controls driving motor 2 with 1 turn of cutter cutter hub
Dynamic, when cutter cutter hub 1 rotates, chamfering tool 3 can act on effective 14 surface of chamfering, process to effective 14 surface of chamfering,
To remove the burr of effective chamfering surface comprehensively, and when the effect of chamfering tool 3, deburrer 4 also be can rotate, in crankshaft end
Face centre bore outer end position processes deburring chamfering, and when processing deburring chamfering, will occur during grinding crankshaft end-face,
And the burr inwardly dug into chamfer site is struck off, to effectively realize deburring, ensures effective chamfering cleaning in this way
Degree meets the requirements, so that error is eliminated to crankshaft body accurate positioning when conical centre fitting holds out against crankshaft end-face centre bore, thus
It improves subsequent polishing and homework precision is processed in dynamic balancing.Engine crankshaft centre bore chamfer machining cutter of the invention, structure letter
It is single, it is at low cost, deburring effectively can be carried out to the effective chamfering and deburring chamfering processed in crankshaft end-face centre bore, improved
The especially effective chamfering surface finish of deburring chamfering, so as to crankshaft sheet when conical centre fitting holds out against crankshaft end-face centre bore
Error is eliminated in body accurate positioning, to improve subsequent polishing and dynamic balancing processing homework precision, improves this constitution of engine crankshaft
Amount.
Described 1 other end of the cutter cutter hub setting Cutting tool installation manner groove I 9 and Cutting tool installation manner groove II 10, in Cutting tool installation manner groove I 9
Chamfering tool 3 is installed, deburrer 4 is installed in Cutting tool installation manner groove II 10, deburrer blade 8 and crankshaft axis 7 it

The structure of burr chamfering 15,14 outer edge of effective chamfering is in conjunction with 15 inside edge of deburring chamfering.Above structure,
The cooperation of angle cutter and deburrer, it is disposable efficiently to complete deburring operation, burr is reduced to crankshaft body subsequent job
Positioning negative effect.
Effective chamfering 14 arranged that deburring chamfering 15 was along crankshaft end-face centre bore 13 1 along crankshaft end-face centre bore 13 1 weeks
Week arrangement, the included angle value between effective 14 surface of chamfering and crankshaft axis 7 be set smaller than 15 surface of deburring chamfering with
The structure of included angle value between crankshaft axis 7, when engine crankshaft ontology 16 carries out polishing and dynamic balance treatment, positioning
The conical centre outer surface of engine crankshaft ontology 16 is configured to the structure contacted with effective 14 surface of chamfering.Said mechanism,
Conical centre can be installed in crankshaft end-face center of gravity hole, and with effective chamfer contact, realize crankshaft body positioning, crankshaft body can
With rotation, to be ground, buff spindle neck, polishing connecting rod neck, and dynamic balancing measurement is carried out to crankshaft body.
The driving motor 2 is connect with the control unit 18 that can control 2 start and stop of driving motor and rotational speed regulation, driving
Motor 2 is configured to the structure rotated with cutter cutter hub 1.Above structure, control unit can control driving motor rotation
And rotational speed regulation, to meet the different demands of different crankshaft body operations.
Chamfering tool positioning bolt 19, Cutting tool installation manner are screwed in the threaded hole I of I 9 lateral location of Cutting tool installation manner groove
Deburrer positioning bolt 20 is screwed in the threaded hole II of II 10 lateral location of slot.Above structure is positioned by chamfering tool
Bolt 19 realizes reliable location to chamfering tool, avoids the chamfering tool stress when carrying out subsequent job to crankshaft body and moves
Dynamic play, and reliable location is carried out to deburrer by deburrer positioning bolt 20, avoid to crankshaft body into
Stress when row subsequent job and move play.
Engine crankshaft centre bore chamfer machining cutter of the present invention is passing through drilling device in engine crankshaft sheet
After processing crankshaft end-face centre bore on body, effective chamfering can be also processed in crankshaft end-face centre bore, then again by crankshaft sheet
Body is fixed, and control cutter cutter hub is mobile in place, and is controlled driving motor band cutter cutter hub and rotated, when cutter cutter hub rotates,
Chamfering tool can act on effective chamfering surface, process to effective chamfering surface, to remove effective chamfering surface comprehensively
Burr, and chamfering tool act on when, deburrer also can rotate, and process unhairing at crankshaft end-face centre bore outer end position
When piercing chamfering, and processing deburring chamfering, will occur during grinding crankshaft end-face, and inwardly digs the hair into chamfer site
It lunges row to strike off, to effectively realize deburring, ensures that effective chamfering cleannes meet the requirements in this way, so that conical centre fitting top
To crankshaft body accurate positioning when tight crankshaft end-face centre bore, error is eliminated, is made to improve subsequent polishing and dynamic balancing processing
Industry precision.Engine crankshaft centre bore chamfer machining cutter of the present invention, structure is simple, at low cost, can be effectively to song
The effective chamfering and deburring chamfering processed in axial end centre bore carry out deburring, so that improving deburring chamfering especially has
Chamfering surface finish is imitated, burr will not influence conical centre positioning crankshaft, so that conical centre fitting holds out against crankshaft end-face centre bore
