It is marked in figure are as follows: 1, digital control lathe chuck；2, lathe inner cone quill spindle；3, lathe center frame；4, special roller
Set；5, rubbing down motor；6, transition connector sleeve；7, Tool-rest of Numerical Control Lathe；8, white fused alumina polish-grinding grinding wheel；9, rubbing down motor seat board.
Specific embodiment
Below with reference to specific embodiment, the utility model will be further described.
As shown in Figure 1, a kind of tailstock of heavy-duty lathe quill spindle internal taper hole grinds prosthetic device, including digital control lathe chuck
1, one end is mounted on the lathe inner cone quill spindle 2 on digital control lathe chuck 1, and the other end of lathe inner cone quill spindle 2 passes through
Special roller set 4 is mounted on lathe center frame 3, and special roller covers 4 one and is fixed on lathe center frame 3, and other end has
Groove is fixed with bearing in the groove, guarantees that the groove is capable of clamping bearing outer ring two sides again while holding bearing top circle
End face, the inner conical surface of corresponding lathe inner cone quill spindle 2 is on Tool-rest of Numerical Control Lathe 7 by being equipped on rubbing down motor seat board 9
Rubbing down motor 5 is equipped with white fused alumina polish-grinding grinding wheel 8 by transition connector sleeve 6 on the output shaft of rubbing down motor 5.
Bearing in 3 groove of lathe center frame is consistent with the rotating coaxial degree of the output shaft of rubbing down motor 5 between the two, hangs down
Straight degree≤0.02mm.
White fused alumina polish-grinding grinding wheel 8 has and wears into angle identical with inner cone hole of main shaft.
KJ61100E/8M numerical control lathe requires accurately technological parameter during implementing rubbing down: the speed of mainshaft is chosen to be
16r/min, feed speed are chosen to be 200mm/min;Bite is strict controlled in 0.005mm；CKJ61100E/8M numerical control lathe is pressed
It is programmed according to inner cone pore size and completes internal taper hole reconditioning processing.
Mainly for the local hard spot and high salient point in internal taper hole, reconditioning effect to be achieved is to guarantee internal taper hole for reconditioning
With concentricity requirement≤0.02mm of outer circular journal bearing position；And then guarantee that all technology acuracy grades for meeting intensely processed products are wanted
It asks.
Tailstock of heavy-duty lathe quill spindle reconditioning technology mainly uses unique main shaft installation way, i.e. chuck adds centre frame
Installation way, the design that central frame roller is capable of clamping bearing outer ring both sides of the face using that can hold bearing top circle again simultaneously；It beats
Table centering position is using bearing position at front and back two as technological datum；The rotating coaxial degree of main shaft itself, verticality when ensuring to repair≤
0.02mm；Using the polishing motor of 2.2Kw, technological parameter requires 2 poles, power 2.2Kw, 2840 ~ 2900r/min of revolving speed；Design
Unique polishing transmission connection device, one end clamp electric machine main shaft, and the other end clamps white fused alumina polish-grinding grinding wheel (white fused alumina grinding wheel thing
First to wear into angle identical with inner cone hole of main shaft), the two is all made of clearance fit, and equipped M10 jackscrew is fixed.
CKJ61100E/8M numerical control lathe requires accurately technological parameter during implementing rubbing down: the speed of mainshaft is chosen to be 16r/min,
Feed speed is chosen to be 200mm/min;Bite is strict controlled in 0.005mm；CKJ61100E/8M numerical control lathe is according to internal taper hole
Internal taper hole reconditioning processing is completed in size programming.Reconditioning mainly in internal taper hole local hard spot and high salient point, reconditioning to be reached
To effect be guarantee internal taper hole and outer circular journal bearing position concentricity requirement≤0.02mm；And then guarantee to meet intensely processed products
All technology acuracy class requirements.
Embodiment: device model: C61250E*8/32 lathe, the equipment are finishing equipment, incidentally process some DN700-
The pipe die of DN1000 slightly adds blank, and workpiece shapes are irregular, lays particular stress on, and uneven penetration of a cutting tool is serious when processing, quill spindle internal taper hole
Hard spot is more, and irregular grinding leads to oval phenomenon occur for a long time, in order to restore the original service precision of spare part as early as possible.Using
Above-mentioned prosthetic device, first with general grinding wheel to 1:7, (80/ major part ￠ 103 of microcephaly ￠) internal taper hole goes hard spot to handle, then
White fused alumina grinding wheel is worn into 1:7 taper by auxiliary mould again.Whole internal cone hole machine is programmed on numerical control CKJ61100 vehicle
Grinding.Until inner hole grinding circularity, inner hole are up to standard with outer circular journal bearing position concentricity within i.e. inside and outside concentricity 0.02.Finally
Precise measurement wears into type internal taper hole, and with this having a size of top outside standard match grinding, contact area reaches 95% or more, on original equipment
Examination processing 2-3 branch finishing product is that important judgment basis tries the quill spindle of grinding-shaping with the quality assurance degree of product
Comprehensive assessment is carried out with effect, is able to satisfy product processing technique requirement completely.
