Description
Technical field
The utility model belongs to deep hole machining field, particularly relates to a kind of train shaft deep hole machining and leads straight device.
Background technology
Deep hole machining be the cutter designed by meeting existing application the manufacture field dominated.Many different industries all can relate to deep hole machining, but most widely used be energy industry and aerospace.Originally some deep-hole parts feature seems and is difficult to realize, but by the nonstandard cutter solution of expert design except solving processing problems, also can guarantee high efficiency and free of errors carry out deep hole machining.
Now the demand in complicated hole is constantly increased, and in the urgent need to shortening process time, thereby promoting the development of modern Deep-Hole Drilling Technology.Recent decades, gun drilling is all a kind of high-efficiency machining method adopting hard alloy cutter, but at the bottom of hole, the bottleneck of boring highlights day by day.
Now, this manufacture field obtains used in combination usually based on standard cutter and nonstandard cutter of success, and experience incorporates in customized deep hole processing cutter by its design.This kind of cutter is furnished with the high accuracy handle of a knife of lengthening, band has support function and integrated form reamer, be combined up-to-date cutting edge flute profile and blade material and cooling fluid and chip efficiently again to control, just can obtain required high-quality processing under the highest penetrance and processing safety.
In gun drilling, the small diameter bore of below 1mm adopts carbide gun drill to process; For 15mm and above hole, general employing welds cutting drill head; And for 25mm and above hole, then adopt indexable cutter blade drill head, thus realize drilling very efficiently.Modern indexable insert tip, throw away tip technology and drill pipe system are also for deep hole machining provides the new possibility using customized cutter.
When hole depth is more than 10 times of apertures, the hole processed is general very dark.Hole depth just needs special technology when reaching 300 times of footpaths, and adopts single tube drill bit or two-tube drill bit to carry out drilling.Be machined in the lengthy procedure bottom this some holes, needing to use correct motion, tooling setup and suitable cutting edge just can complete the processing of inner chamber, groove, screw thread and die cavity.Gripper shoe technology is another key areas, also most important in gun drilling, and it also develops very fast as a part for Deep-Hole Drilling Technology now, is wherein just included in the exploitation that this field can realize more high performance high-quality cutter.
Be exactly hole very dark in the huge generator shaft in processing power station to cutter and application proprietary technology another example exigent during hole drilling.In this case, power-generating industry expert Generpro company must to process the forged steel part of 90 tons with the asymmetric mode of shaft centre line, and wherein hole depth is close to 5.5m, and diameter is more than 100mm.This type of deep hole must depart from certain angle and carry out drilling, and when exiting, position of related features must within 8mm.
Nonstandard cutter solution all can realize required closed tolerance and surface quality in the hole machined of whole relative complex.Process comprises first carries out a gun drilling, then adopts floating reamer to carry out fine finishining.Then, in the degree of depth of 1.5m, obtained the hole of 115 mm diameters by reaming and ream.Position more shallow in hole is carried out reaming, grinding and chamfering again and is shaped.Finally, form the inner chamber of two band chamferings by boring and reaming, also obtain final finished size by grinding.
In deep hole machining, because boring bar is more elongated, its twisting vibration will directly affect machining accuracy, tool life and stock-removing efficiency.If effectively control boring bar vibration, deep hole machining precision can be improved.
Because limiting by aperture size, the draw ratio in hole is comparatively large, and drilling rod is thin and grow, poor rigidity, easily produces vibrations, and boring easily wanders off, and thus support guide is very important.This point is more outstanding in drill gun lathe.
