Abstract
A reaming and milling combined cutter comprises a cutter handle and a cutter head, the cutter head is radially provided with a center hole and mounted at one end of the cutter handle and comprises three milling blades and three reaming blades, and the three milling blades and the three reaming blades are in staggered arrangement and of an integral structure. The reaming and milling combined cutter is long in service life and high in machining precision, machining can be completed by one-time operation by adopting the cutter head combined with a milling cutter and a reamer, a working procedure is omitted, labor power and working time are saved, production cost is decreased substantially, and better desired effect can be achieved. Moreover, effect of reaming can be also achieved on the condition that machining allowance is large.
Description
Technical field
The utility model relates to a kind of machining tool, and particularly a kind of hinge is milled the combination cutter.
Background technology
At present, also increasingly high because design level is increasingly high to the specification requirement of processing parts, the hole of the various high-precision requirement of ubiquity processing in the mechanical part processing.Because the having relatively high expectations of aperture all is to adopt boring earlier usually, reaming again, finish ream, to reach high-precision requirement.
The effect of reamer is to be used for fraising, improves the fineness in hole, guarantees the dimensional accuracy in hole, but prerequisite be the allowance of reamer can not be too big, generally all be about 0.15mm, if big, just can not obtain expected effect.Like this, just must behind drilling operating, add a step reaming operation again, fraising again behind the allowance of assurance reamer.Numerous and diverse like this step, both wastes of manpower delay man-hour again, and production cost is increased substantially, and in the process that repeats operation, the precision of fraising is difficult for holding.
The utility model content
The purpose of the utility model provides a kind of hinge and mills the combination cutter, when this cutter allowance is big, also can reach precision.
The technical scheme that adopts is:
A kind of hinge is milled the combination cutter, comprises handle of a knife and cutter head, and cutter head radially offers centre bore, and cutter head is installed in handle of a knife one end;
Cutter head comprises three pieces of milling cutter swords and three pieces of reamer swords, and three pieces of milling cutter swords and three pieces of reamer swords are laid staggeredly on cutter head, and are an overall structure;
Become 80 ° of angles respectively between above-mentioned three pieces of milling cutter swords and three pieces of reamer swords, the relief angle of three pieces of milling cutter swords and three pieces of reamer swords is respectively 20 °;
The wide 1.0cm that is respectively of the blade of above-mentioned three pieces of milling cutter swords, the wide 0.2cm that is respectively of the blade of three pieces of reamer swords.
The advantage of the utility model is:
The utility model long service life, machining accuracy is high, the cutter head that adopts milling cutter and reamer to combine; One-stop operation just can be accomplished processing tasks, reduces one procedure, not only saves manpower but also practice thrift the working time; Reduce production cost significantly; And can better produce a desired effect, even under the bigger situation of allowance, also can reach the effect of ream.

The specific embodiment
A kind of hinge is milled the combination cutter, comprises handle of a knife 7 and cutter head, and cutter head radially offers centre bore 8, and cutter head is installed in handle of a knife one end;
Cutter head comprises that 1,2,3 and three pieces of reamer swords 4,5,6 of 4,5,6, three pieces of milling cutter swords of 1,2,3 and three pieces of reamer swords of three pieces of milling cutter swords are laid staggeredly on cutter head, and is an overall structure;
1,2,3 and three pieces of reamer swords 4,5 of above-mentioned three pieces of milling cutter swords, become 80 ° of angles between 6 respectively, the relief angle of 1,2,3 and three pieces of reamer swords 4,5,6 of three pieces of milling cutter swords is respectively 20 °;
The wide 1.0cm that is respectively of the blade of above-mentioned three pieces of milling cutter swords 1,2,3, the wide 0.2cm that is respectively of the blade of three pieces of reamer swords 4,5,6.
