Description
Technical field
The utility model relates to a kind of cutter, is specifically related to a kind of processing five-way cutter.
Background technology
Current bicycle bottom bracket adopts process tool to be first use boring cutter boring five-way hole on Boring machine, re-use tapping knife tapping on tooth machining unit, such processing mode efficiency is low, and need Boring machine and these two equipment of tapping, human input is also many, causes cost higher, and in process, five-way needs secondary to locate, can improve error, Product processing quality not easily ensures.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of processing five-way cutter, and can locate the processing of five-way by clamped one time, enhance productivity, guarantee machining accuracy, reduces costs.
The utility model in order to the technical scheme solving its technical problem and adopt is: a kind of processing five-way cutter, comprise knife bar, one end of described knife bar can be installed in CNC machine, the other end of described knife bar detachably fixes at least one bore hole blade, the middle part axially spaced-apart of described knife bar is removably fixed with first and second milling threading tool sheet, the blade of first and second milling threading tool sheet described is less than the distance of blade to knife bar axial line of described bore hole blade to the distance of knife bar axial line, and the distance between first and second milling threading tool sheet described is greater than the axial length of five-way.
As further improvement of the utility model, described bore hole blade is two, is symmetricly set on the both sides of the knife bar other end.
As further improvement of the utility model, described first milling threading tool sheet is between described bore hole blade and the second milling threading tool sheet.
As further improvement of the utility model, first and second milling threading tool sheet described is positioned at the both sides of described knife bar axial line.
As further improvement of the utility model, the middle part of described knife bar becomes cylindric, and the other end of described knife bar is horn-like towards what open away from knife bar one extreme direction, the other end of described knife bar and the middle part smooth connection of described knife bar.
The beneficial effects of the utility model are: by first, two milling threading tool sheets and bore hole blade are arranged on same knife bar simultaneously, utilize High Precision CNC airport, first bore hole is carried out to bicycle bottom bracket, without the need to five-way is carried out secondary location after bore hole completes, just can carry out the processing of milling tooth, by first, two milling threading tool sheets mill out the tooth line at five-way two ends respectively, whole process take five-way as benchmark, clamped one time location machines five-way, bore hole and milling tooth operation are merged, avoid accumulated error, enhance productivity, ensure processing precision of products, reach full non-defective unit requirement, reduce cost simultaneously.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation processing five-way cutter of the utility model.
Detailed description of the invention
Embodiment: a kind of processing five-way cutter, comprise knife bar 1, one end of described knife bar can be installed in CNC machine, the other end of described knife bar detachably fixes at least one bore hole blade 2, the middle part axially spaced-apart of described knife bar is removably fixed with first and second milling threading tool sheet 3,4, the blade of first and second milling threading tool sheet described is less than the distance of blade to knife bar axial line of described bore hole blade to the distance of knife bar axial line, and the distance between first and second milling threading tool sheet described is greater than the axial length of five-way.
Add man-hour, first one end of knife bar is installed in CNC machine, and will the five-way Set and Positioning of processing be needed good, then knife bar is declined, by the bore hole blade of the other end of knife bar, size unnecessary before milling tooth in five-way is removed, complete the work of bore hole, because the blade of first and second milling threading tool sheet to be less than the distance of blade to knife bar axial line of bore hole blade to the distance of knife bar axial line in bore hole process, therefore first and second milling threading tool sheet can not encounter five-way; After bore hole completes, continuation decline knife bar makes bore hole blade reach the outside of five-way, move knife bar to suitable position simultaneously, the position making the first milling threading tool sheet be in five-way one end to need milling tooth, then rotate forward and carry out first time milling tooth, because the distance between first and second milling threading tool sheet is greater than the axial length of five-way, therefore, when the first milling threading tool sheet milling tooth, the outside that the second milling threading tool sheet is positioned at five-way can not contact with five-way; First time milling tooth completes follow-up decline knife bar makes the first milling threading tool reach the outside of five-way, and the position making the second milling threading tool sheet be in the five-way other end to need milling tooth, then rotate backward and carry out second time milling tooth, after second time milling tooth completes, whole process just all completes, finally knife bar is risen, five-way is pulled down from fixture.Whole process only needs clamped one time to locate, and just can be completed the operation of bore hole and milling tooth, substantially increase production efficiency, ensured the machining accuracy of product simultaneously by CNC airport by the process of a knife bar lifting.
Described bore hole blade is two, is symmetricly set on the both sides of the knife bar other end.By two bore hole blades, improve bore hole efficiency, and make bore hole more even.
Described first milling threading tool sheet is between described bore hole blade and the second milling threading tool sheet.Certainly the position of first and second milling threading tool sheet can be replaced mutually, on processing not impact.
First and second milling threading tool sheet described is positioned at the both sides of described knife bar axial line.Screw thread due to five-way two ends is contrary, therefore milling can be facilitated to remove contrary screw thread the both sides that first and second milling threading tool sheet is arranged on the both sides of knife bar axial line.
The middle part of described knife bar becomes cylindric, and the other end of described knife bar is horn-like towards what open away from knife bar one extreme direction, the other end of described knife bar and the middle part smooth connection of described knife bar.
