Description
Technical field
The utility model relates to the cutter of high precision inner-pore processing, relates in particular to a kind of special reamer that meets cylinder bore high-precision requirement.
Background technology
At present, known hole forming method is drilling, and the machining accuracy of drilling is lower, generally can only reach IT11-IT13, surface roughness is generally Ra12.5 ~ 1.6 μ m, reamer is to process on the basis of former bottom outlet when reaming, therefore cannot improve positional precision and the linearity of axially bored line.
Drill bit is when processing hard material simultaneously, and it is not enough that edge strength is often disliked; It is long that chisel edge is disliked, and the anterior angle of chisel edge is very large negative value, thereby will produce very large axial force; The main cutting edge of drill bit is very long, is unfavorable for minute bits and a chip breaking; The front clearance of margin of drill place front cutting edge is null value, causes the friction between minor flank and hole wall to strengthen, and cutting temperature rises, and the wearing and tearing of drill bit outer rim corner are larger, and machined surface roughness worsens.
Utility model content
For the problem of above-mentioned existence, overcome that existing drilling machining accuracy is not high, surface roughness is poor and cannot improve the positional precision of axially bored line and the deficiency of linearity, the utility model provides a kind of cylinder bore special reamer.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of cylinder bore special reamer, described reamer comprises reamer cutter head, floating cutter arbor and centrum handle of a knife, described reamer cutter head and floating cutter arbor are threaded connection, described reamer cutter head top is provided with blade structure, described blade structure inner side is provided with the cylinder land of 0.4-0.6mm, the both sides of described reamer cutter head are provided with rectification blade, described rectification blade is that leading portion is cylindrical, the blade of back segment back taper, and the center of described reamer cutter head is provided with Cooling Holes.
The steel part that the most applicable processing of cylinder land of blade structure inner side is hardened, the steering capability of cutter is fine, and has very high cutter life; Reamer correction portion maximum diameter retains one section of cylindrical edge simultaneously, and part is after this done in an inverted cone, to reduce the unlikely surface scratch of friction on sword and positive ream surface.
As a kind of improvement of the present utility model, the number of teeth of described reamer cutter head is the pitch structure of six tooth deciles; This structure has improved machining accuracy and cutter life, is also convenient to reamer simultaneously and makes and measure, and the teeth groove of six tooth reamers, for chip removal provides enough spaces, prevents that iron filings from blocking in hole, affects working life of reamer.
As a kind of improvement of the present utility model, described floating cutter arbor and centrum handle of a knife directly adopt floating connection, by cone pin, are located by connecting; Revise to the full extent the precision of lathe, guaranteed positional precision and the linearity of good axially bored line.Split type reamer had both improved the range of work, was convenient to again change reamer, greatly reduced processing cost.
As a kind of improvement of the present utility model, described blade structure is selected the blade of E252 or YW1 model; Its red hardness of the blade of this model is better, can bear certain impact load, is the good alloy of versatility, is suitable for the processing of the low machinability steel materials such as heat resisting steel potassium steel stainless steel, is also suitable for the processing of ordinary steel and cast iron.
As a kind of improvement of the present utility model, the middle part of described floating cutter arbor and centrum handle of a knife is provided with cooling bath and is communicated with the Cooling Holes on reamer cutter head; Cooling fluid can flow to the surface of reamer and workpiece smoothly from this Cooling Holes, be cooled in time and iron filings are gone out from a undressed side blow, and the friction when reducing Tool in Cutting and between workpiece, affects machining accuracy.The sufficient supplies of cooling fluid can effectively be controlled heat in metal cutting again, improves the service life of reamer.
The utility model has the advantage of: its machining accuracy of cutter of the present utility model can reach IT6 ~ IT7, machined surface roughness can reach Ra1.6 ~ 0.4 μ m, and its floating structure can revise the precision of lathe, guarantee positional precision and the linearity of good axially bored line.
