A kind of cutting mechanism and its application method making shallow mouth in annular workpieces inner surface
The present invention relates to cutting fields to be more particularly related to a kind of cutting mechanism that shallow mouth is made in work piece inner surface.
In machining manufacturing process, annular workpieces are a kind of essential components, there is very extensive make
With.Under many operating conditions, such as the needs of reference, the setting of anti-counterfeiting code etc., the interior table in annular workpieces is needed
Carry out making the cutting of shallow mouth on face, under normal circumstances, operator still holds blade and gos deep into annular workpieces carrying out by hand
Scribing, this mode of operation and its be easy to cause the unqualified of shallow mouth, or even will cause scrapping for annular workpieces, for some high
For expensive or accurate ring tool, even more have no way of doing it.Although there are also can be deep into inside annular workpieces at present
Device, however the control precision of these equipment is opposite is short of, and the stability of clamping does not reach requirement, and universal performance is poor, control
System complex, cost are excessively high.Therefore, for this status, the more of shallow mouth are made in work piece inner surface there is an urgent need to develop a kind of
Function cutting mechanism, to meet the needs of actual use.
Pertinent literature [CN106217052A] discloses a kind of wheel rim machining tool of wheel hub, it solves how to improve wheel
The problem of machining accuracy is improved while the processing efficiency of rim outer surface, however merely by setting lathe tool and specific forming cutter
Tool carries out Roughing and fine machining to the wheel rim outer surface of wheel hub by the way of vehicle, mill Compound Machining, can not be to annular inner surface
It carries out accurately easily cutting shallow mouth operation.
Pertinent literature [CN105415058A] discloses a kind of lathe, including lathe body and rotary workbench, the dress
A kind of only lathe mechanism is set, cutting function is not had, although having frock clamp, is still fallen within more typical
The tooling type of machine tool field, overall mechanism is more heavy, cannot achieve the cutting operation that work piece inner surface makes shallow mouth.
Pertinent literature [CN206445221U] disclose it is a kind of for processing the lathe of electric motor end cap, including lathe base,
The clamp assembly for clamping electric motor end cap to be processed on lathe base, the sliding that is connected on lathe base of sliding are set
Platform, the toolbox being arranged on sliding platform, clamp assembly include chuck body and be arranged on chuck body for motor side
Lid carries out the outer support fixture that outer support clamps in fact, the device is still a kind of typical lathe mechanism, passes through tool changing device pair
Each side of end cap is processed, which is not cutting mechanism, also can not make shallow mouth to annular workpieces inner surface.
