Description
Technical field
The utility model is related to a kind of machining tool, more particularly to a kind of machining tool of use Boring machine processing ultra-deep blind hole.
Background technology
Process ultra-deep blind hole when, sometimes using boring machine, deep hole boring machine award oily device and cooling system is only applicable to through hole
Processing, coolant pressure is also small.And when carrying out blind hole processing, chip need to be discharged from blind hole oral area, because chip removal mode occurs
Change, original head of a bed chip removal mode can not meet the requirement of processing.Also there is processing ultra-deep blind hole lathe process, but exist
Processing efficiency is low, required Boring Bar high cost, and the problem of drill bit and serious blade abrasion.
The content of the invention
The utility model provides a kind of ultra-deep blind hole processing tool, solves the problem with Boring machine processing ultra-deep blind hole.
The utility model solves above technical problem by the following technical programs：
A kind of ultra-deep blind hole processing tool, including scroll chuck and sealing are taken over a business, between scroll chuck and sealing are taken over a business
Workpiece to be machined is connected with, the right flank apical grafting taken over a business in sealing awards oily device sleeve pipe, and guiding is socketed with oily device sleeve pipe is awarded
Set, knife bar is provided with fairlead, deep-hole boring head is connected with the left end of knife bar, boring has been positioned apart from deep-hole boring head
Head support sliver, boring head support sliver be abutted against with the inner chamber of fairlead together with, chip-removal hole is provided with knife bar, knife bar with
Feed liquor circular passage is provided between fairlead.
The internal diameter of fairlead is identical with the aperture drilled on workpiece to be machined.
If being machined with the part of such a ultra-deep blind hole from lathe, after the aperture of first drilling certain depth, then endoporus car is used
Knife turning increases endoporus, turning reaming again is then bored again, so sublevel is progressively processed repeatedly, 2 meters of processing 300 mm diameter depth
Blind hole, need 80 hours or so, and drill bit, turning insert consumption is serious, when turning is to blind via bottom, because knife bar overhang
Long, common Boring Bar can not meet requirement, and 10 nonstandard Boring Bar need to be more than from damping coefficient, and cost is greatly increased.
The utility model, with support and anti-vibration functions, is not only processed because drill bit and boring head are per se with support sliver
Efficiency high, the blind hole of 2 meters of processing 300 mm diameter depth, is only needed 30 hours, low cost, processing efficiency improves 1 times than lathe
It is many.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model before processing；
Fig. 2 is the structural representation of the utility model work in-process.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of ultra-deep blind hole processing tool, including scroll chuck 1 and sealing take over a business 3, and 3 are taken over a business in scroll chuck 1 and sealing
Between be connected with workpiece to be machined 2, sealing take over a business 3 right flank apical grafting award oily device sleeve pipe 4, in oily device sleeve pipe 4 is awarded cover
Fairlead 5 is connected to, knife bar 6 is provided with fairlead 5, deep-hole boring head 8 is connected with the left end of knife bar 6, on deep-hole boring head 8
Boring head support sliver 7 is positioned apart from, boring head support sliver 7 is set together with being abutted against with the inner chamber of fairlead 5 in knife bar 6
Chip-removal hole 9 is equipped with, feed liquor circular passage 10 is provided between knife bar 6 and fairlead 5.
The internal diameter of fairlead 5 is identical with the aperture drilled on workpiece to be machined 2.The clamping of workpiece to be machined 2 is in the equipment head of a bed
Scroll chuck 1 on, the sealing that afterbody is installed with awarding on oily device sleeve pipe 4 is taken over a business 3 and held out against, and before the special feed of deep-hole boring head 8, leans on
Be positioned apart from deep-hole boring head 8 boring head support sliver 7 be positioned in fairlead 5, the size of fairlead 5 with will drilling zero
Part hole size is consistent.After deep hole drill is pierced in part, drill bit is existed by the boring head support sliver 7 at the rear portion of deep-hole boring head 8 all the time
It is supported in the endoporus that anterior drill bit is got out, the hard alloy after boring head supports sliver 7 by quenching is made, except to depth drill
Outside head is oriented to, vibrationproof vibration-damping function is also acted as, chip removal uses interior chip removal method, and high-pressure coolant is from knife bar 6 and fairlead 5
Between be provided between feed liquor circular passage 10 and enter cutting zone, and chip is discharged from the chip-removal hole 9 in knife bar 6.
