Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making the creative labor
All other embodiments obtained, shall fall within the protection scope of the present invention.
As shown in Fig. 1 ~ 7, a kind of deep hole boring machine cutter hub, including main body 1, blade 7 and combined guided piece, the main body 1 one
Guide groove is evenly equipped with the wall of side, 1 other end of main body is equipped with the flat thread 9 and clamping platform 10 of double end, guide groove and main body 1
Centerline parallel, combined guided piece includes gib block 2 and guide pad 3, and gib block 2 is connected by bolt 4 with main body 1,1 side of main body
Mounting groove is additionally provided with wall, tool section 6 is installed in mounting groove, blade 7 is connected by tilting bolt 8 with tool section 6, is set in main body 1
There is water channel 5,5 one end of water channel is connected with mounting groove 12, and 5 other end of water channel is connected by interstitial hole and the center inlet opening 11 of main body 1
It is logical.
The utility model is made of 6 parts, is the bolt of 3,3 M5 of the guide pad of gib block 2,6 of main body 1,3 respectively
（For connecting gib block 2 and main body 1）, 1 M6 inclination bolt 8, tool section 6.The utility model is as follows when processing：It is first
The guide groove and water channel 5 of combined guided piece of installation are first processed on the body 1；Processing M5 among guide groove on the body 1
Internal thread；The mounting groove of processing installation tool section and the collet threaded hole with certain angle in main body；Combined guided packaged
Fit in main body, tool section is fixed in main body.
In the application, three it is combined guided it is packaged fit in main body, refine to the size of deep hole to be processed, three in main body
A combined guided piece remains a concentric circles, is clearance fit with the aperture after machining, processed product is rotating
During, three combined guided piece supports internal diameter all the time, and three combined guided piece of utilizations, 6 guide pads 3 refine at work
Size plays guiding in deep hole afterwards, ensure that the straightness after the completion of Product processing meets product design requirement.Processing
During blade produce cutting heat punching bits water channel can not drop, by increase a blade direct cooling water channel 5, can
Iron filings are washed away, most importantly the cutting heat produced on blade is taken away, reduces blade produced by working angles
Heat, extend the service life of blade.
When using the utility model, the flat thread 9 of double end is close-connected with equipment, and the flat thread of double end can
Quickly the utility model is connected with equipment, reduce the time of connection utility model.Increased stopping table 10 is to protect
It is consistent with using the straightness after equipment connection to demonstrate,prove utility model, effectively solves straight line after utility model is connected with equipment
Spend it is inconsistent caused by converted products it is unqualified.
Preferably, the angle α for tilting bolt 8 and 1 radial direction of main body is 20 ° or so.Tilt bolt 8 and be arranged on collet threaded hole
Interior, for fixing blade 7, the guide pad 3 is that YG8 hard alloy is fast.
The utility model process is as follows：
1. making main body, suitable material of main part is selected（38CrMoAL, 70 bars, often saves 250mm）And carry out blanking；
In heat treatment stages, new material of main part heat treatment hardness is controlled, is ensured in HRC48-52；Main body carries out nitrogen treatment, after processing
Nitride thickness in 0.6mm；Combined guided piece of size is manufactured according to the aperture size of deep hole；Ensure the circle bounce of main body,
Double Tops smart car shape ensures circumference bounce≤0.015mm；Solve double end flat thread processing technology and with cylindrical concentricity
It is required that；It ensure that the requirement of the angle and positional precision of milling process installation tool section screw hole.Combination is led according to assembly precision
Being fitted over to packaged in main body, after installation is complete, height is different from combined guided piece in main body, not on same circle,
When fine grinding can so be caused, discontinuity, the main body circular runout after fine grinding is bigger, just needs at this time by hand in emery wheel
Upper Cu Lve Xiu circles, hard alloy reconditioning on emery wheel are extremely difficult.Some combined guided piece is higher by very much, Dao Zhi Xiu in welding
Circle is highly difficult；The size of fine grinding cutter hub can effectively be controlled.
2. make an end-face central hole and the other end center inlet opening 11 of main body, Double Tops finished profile, double is carried out
Head square screw thread and the clamping platform of positioning, ensure circumference bounce≤0.015mm at three, recycle Five-axis NC Machining Center to make
Guide groove, water channel, at 3 M5 screw hole, the mounting groove of tool section is installed, its main portions is exactly for fastening the 20 of tool section °
M6 bottom outlets, and preset M6 screw threads, it will ensure 20 ° of angles of thread and the positional precision of guide groove.Control and lead in heat treatment stages
The heat treatment hardness of body,（Ensure in HRC48-52）.Main body after shaping carries out nitrogen treatment, and nitrogen treatment layer thickness exists
0.6mm.Main purpose is to avoid some unnecessary damages in use, ensure that the integrality of main functionality, can be with
Secondary use main body again.After the completion of main body turn blue.
3. combined guided piece of making：Blanking, the big steel plate air cuttings of 45# are 45 × 25 × 15 fritters；Rough mill guide pad；Line is cut
Cut gib block.Gib block is key position, and size is all very tight, and geometric tolerance is very more, wire cutting process be positioned to standard,
Surely, it is accurate to knife process.Welding the supporting block on gib block requires material more special, the hard alloy of YG8, welding process
Control the cushion block height of YG8 hard alloy.Plain grinding：Guide pad width with cutter hub on assemble width tolerance be 20+0.012-
0.006 tolerance is very small, and the guide pad welding slag after welding is relatively more, hardly possible cleaning, and cleaning completion rear surface is smooth, also
Ensure width tolerance, it is impossible to overproof.First have to remove bigger welding slag with file, then polished with 6# abrasive paper for metallograph, control ruler
Very little and surface smoothness.After the completion of combined guided block welding, there are the YG8 hard alloy supporting blocks of many remaining welding slags and welding
Height is not waited, it is necessary to upper surface grinding machine polishes hard alloy blocks supporting block, makes the guide pad 12+0.05-0.05 of each high
It is low equal.
4. assembling：Guide pad groove and combined guided piece of width on cutter hub are tight fits.First new combined guided piece
Put the guide pad groove in main body, then the screw-driving with M5 into, due to the assembling of tight fit, it is all to use aluminium bar to assemble each time
Knock, shake shake, then tighten screw, be repeated 3 times back and forth, there are three guide pads on each cutter hub, each piece of assembling repetition is identical
Action, assembling complete cutter hub need 1 it is small when, carry out cavetto after the completion of assembling.
5. refine aperture size to be processed needed for cutter hub, and ensure combined guided piece, stopping table and double end flat thread
Concentricity.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
Protection domain within.
