Technical field
The utility model relates to a kind of process tool, specifically in a kind of axial feed stroke and carry out boring and ream again simultaneously, and window that can guide position in hole to cutter guiding drill reamer.
Background technology
At present, process IT8 level hole on to the material such as mild steel, non-ferrous metal time, normally first use drill bit punching, re-use reamer and carry out fine finishining.Sometimes,, because bore position is inclined to one side, before carrying out fine finishining, reamer also need to use expansion cutter to carry out semifinishing.Owing to needing to use different cutters in process, but also increased tool change time, at the bottom of causing working (machining) efficiency, the cost of charp tool increases.
Utility model content
According to being difficult for fine finishining and this technical problem of the time-consuming consumptive material of fine finishining after the boring of above-mentioned proposition, and provide a kind of window guiding drill reamer.The utility model mainly utilizes at the cutting tip of drill bit and sets up reamer sword and guiding sword, thereby plays cutter position location and be convenient to accurately machined effect in hole.
The technological means that the utility model adopts is as follows:
A kind of window guiding drill reamer, comprises shank and the cutting portion with the coaxial setting of described shank, it is characterized in that:
Described cutting portion comprises roughing main cutting portion, fine finishining assisted machining portion and support guide portion;
Described roughing main cutting portion comprises two spiral drill edge grooves and the land that is connected respectively edge, two described drill edge groove neighborings, described land comprises Qing Bei district and margin of drill, and the brill core place that two described drill edge grooves and described land meet at described cutting portion front end mutually forms cutting chisel edge and two drill bit main cutting edges;
In described land Qing Bei district, be provided with described fine finishining assisted machining portion and described support guide portion, described fine finishining assisted machining portion comprises spiral helicine reamer cutting edge groove and reamer land, and described reamer cutting edge groove and described reamer land form reamer main cutting edge at described cutting portion front end;
Described support guide portion comprises spiral helicine guiding flute groove and guiding land, and described guiding flute groove and described guiding land form guiding sword at described cutting portion front end.
Two drill edge grooves of above-mentioned cutting portion are main chip area, and each two of reamer cutting edge groove and guiding flute groove are auxiliary chip area; On the land being connected with drill edge groove, contain and be useful on rough machined margin of drill, reamer land is for fine finishining, guiding land is used for supporting cutter, the size of cutting portion is determined to be in operating process, drill bit main cutting edge, reamer main cutting edge and guiding sword are worked simultaneously, wherein, drill edge groove is associated with reamer cutting edge groove and guiding flute groove.
As preferably, the drill head apical angle of described cutting portion front end is 135 °-140 °.Described drill head apical angle shows as two drill bit main cutting edge place straight lines and is connected the rear angle forming with chisel edge.
As preferably, described roughing main cutting portion, described fine finishining assisted machining portion are identical with the lead angle θ of described support guide portion, and lead angle θ is 30 °-40 °.
As preferably, described reamer main cutting edge tool cutting edge angle γ is 40 °-50 °.
As preferably, described drill edge groove is 90 °-100 ° with described reamer cutting edge groove position phase α scope, and described drill edge groove is 120 °-130 ° with described guiding flute groove position phase β scope.
As preferably, along described cutting portion axial direction, described reamer main cutting edge end is apart from the distance L at described drill bit main cutting edge edge
2for 0.5-1.0mm, described guiding sword end is apart from the distance L at described drill bit main cutting edge edge
1for 1.2-1.6mm.
As preferably, described reamer land edge and described guiding land edge are in same round I, and the diameter of place, described margin of drill edge circle II is than the little 0.1-0.15mm of the diameter of described round I.
Compare compared with prior art, the method that the utility model has adopted drill bit main cutting edge, reamer main cutting edge, guiding sword to combine, drill bit is the same with common drill bit in the time of cutting, and cutting chisel edge first contacts and is cut material surface, and drill bit main cutting edge cuts material subsequently; Reamer main cutting edge is after drill bit main cutting edge, when drill bit main cutting edge enters after Kong Zhongyue 0.5-1.0mm, reamer main cutting edge enters in processed hole thereupon, because reamer main cutting edge diameter is greater than drill bit main cutting edge diameter, therefore now the chipping allowance of reamer main cutting edge in hole is less, and what carry out is Surface Finishing operation.Because roughing is different from accurately machined chipping allowance, roughing excision remainder punching is larger, and because roughing and fine finishining are to process in hole simultaneously, therefore drill bit main cutting edge produces considerable influence to reamer main cutting edge fine finishining meeting; About 1.5mm left and right after reamer main cutting edge enters hole, guiding sword enters processed hole, and cutter is played and supported and firm effect, thus the impact of reduction drill bit main cutting edge on reamer main cutting edge.
In addition, 4 lands altogether, i.e. 2 hinge sword lands and 2 guiding lands, simultaneously in hole, except hole wall having been played to good support and firmly having acted on, be equivalent to hole wall to carry out extruding polishing simultaneously, can obtain the diameter apertures of higher surface smoothness and IT8 level.
The utlity model has the advantages such as simple in structure, practical, hole processing is realized to Roughing and fine machining integrated, reduce the cost of charp tool, working (machining) efficiency is high.The utility model can extensively be promoted at hole manufacture field for the foregoing reasons.
