Description
Technical field
The present invention relates to the efficient lathe of a kind of multi-drill boring processing, and particularly a kind of multiaxis U bores group's main spindle box and U bores group's high-speed numeric control drilling machine.
Background technology
In traditional hole is in the machining, and fluted drill, Ni Zhifu drill are simple in structure, with low cost because of it, can widely apply in radial drill, vertical drill, many spindle combinations drilling machine even electric hand drill.But along with modern mechanical processing at a high speed, the develop rapidly of efficient, Compound Machining aspect, the boring that composite and high rigidity, high strength etc. are difficult for rapidoprint has obtained the essence change because of the invention that the U brill has been arranged.Fluted drill is that rotary cutting by its relative fixed axis is with the instrument of the circular hole of drilling workpiece.Compare with fluted drill, the advantage that U bores is: 1. working (machining) efficiency be at least fluted drill 2-3 doubly; Can directly on workpiece, process 2.U bore, need not centre drill and beat bullport; 3. the cutter hub front end is equipped with removable blade, has reduced the cost that uses.Because the rotating speed of fluted drill is not very high, mainly be the operation principle that relies on rotary cutting, its cooling is required also not high, so the drillstock of fluted drill is elongated usually, and has than many parts and can be positioned at the main spindle box outside.Have at present the brill group main spindle box of forming with a plurality of fluted drills, it is not on the very high porous panel that this multiaxis fluted drill main spindle box is fit to the Working position required precision, compares its working (machining) efficiency and significantly improves with single boring, thereby save a lot of workloads.Yet,, still need adopt U to bore processing for the higher boring of Working position required precision." U brill " is owing to adopt throw away screw fixed blade, knife bar can not shorten when processing parts, therefore, its length is compared with " high speed steel twist drill " and is wanted much shorter (it does not need to stay the sharpening surplus), stability principle according to depression bar, only length shortens and makes its critical pressure Pcr be about more than 1.5 times of fluted drill, therefore the rigidity of " U brill " is more much better than " high speed steel twist drill ", just because of this point, the surface quality in the hole that " U brill " processed and the positional precision of boring are all much better than " high speed steel twist drill ", also just because of its high rigid design, do not need when holing with " centre drill " location with " U brill ", save process time, improved working (machining) efficiency, reduced production cost.Yet, drillstock (main shaft) length that U bores is compared with " high speed steel twist drill " and is wanted much shorter, also must consider the cooling problem in High-speed machining, this support section and cooling segment diameter that makes U bore is bigger, is difficult to realize that a plurality of U rotating shafts U closely arranged side by side bores the group.The patent No. is 200920298240.9 utility model patent " fluted drill and U bore the combined drilling and counterboring main spindle box ", fluted drill and U bored to meet to form together bore group, be applicable to different processing, improved working (machining) efficiency to a certain extent the diverse location required precision.In the present prior art, also do not exist and simultaneously a plurality of U are bored the U brill group who closely combines formation, for adopting U to bore the porous workpiece of processing, just can only process one by one, such processing mode still can not satisfy the high-quality job requirement of high efficiency.
