The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; A kind of roll groover of the present invention; Comprise lathe tool depth-feed mechanism and main motor 1, main reducing gear 2 that is connected with said main motor 1 and the gear-box 3 that is connected with said main reducing gear 2, said gear-box 3 is provided with first output shaft 4 and second output shaft, and said first output shaft 4 connects machine tool chief axis; Said second output shaft connects lathe feed rod 12; Said lathe feed rod 12 is connected with said gear-box second output shaft through differential mechanism 8, and said differential mechanism 8 is provided with driving shaft and left and right output shaft 5,9, and said left output shaft 5 is connected with said gear-box second output shaft; Said right output shaft 9 is connected with said lathe feed rod 12, and said driving shaft connects servomotor 11 through decelerator 10; Be equipped with in the said gear-box 3 driving gear that is connected with said first output shaft 4, with the idler gear 29 of said driving gear engagement and with said idler gear 29 engagements or the shifting slide gear 6 of throwing off; Said shifting slide gear 6 is installed on said second output shaft, and the fixed gear 7 with said shifting slide gear 6 engagements or disengagement also is installed in the said gear-box 3.
For making feed accurate; Said lathe tool depth-feed mechanism comprises the upper slide rest 23 that is connected with lathe tool 22, the mother lead screw 17 and the leading screw 16 that with said mother lead screw 17 be connected affixed with said upper slide rest 23, and said leading screw 16 is through be with 19 to be connected with radial feed servomotor 18 synchronously.Radial feed servomotor 18 is by computer control, and feed is accurate.
Operation principle of the present invention:
One, turning:
After accomplishing being installed of workpiece 25, shifting slide gear 6 and idler gear 29 are thrown off and fixed gear 7 engagements.Shake planker radial feed crank 21, make lathe tool 22 contact workpieces 25, shake planker radial feed crank 21 again, confirm the lathe tool amount through dial 20.Start main motor 1, main motor 1 is through first output shaft, 4 rotations of main reducing gear 2 driven gear casees 3, and first output shaft 4 drives workpiece 25 rotations that are installed on the workpiece chuck 26 through main spindle box 28; Start servomotor 11 and drive decelerator 10; Drive the right output shaft 9 of differential mechanism through differential mechanism 8, the right output shaft 9 of differential mechanism drives feed rod 12 rotations, and feed rod 12 drives the geared sleeve rotation in the planker gear-box 13; Geared sleeve drives bevel-gear sett; 14 rotations of bevel gear driven gear axle, gear shaft 14 and tooth bar 15 engagements that are fixed on the lathe bed 27, gear shaft 14 rotations drive planker 24 and on lathe bed 27, move axially.Carry out the turning of workpiece 25 cylindricals, go out cutter after, close servomotor 11.Tool setting again, feeding start servomotor 11 and make its counter-rotating, carry out reverse turning.So the processing of cylindrical is accomplished in circulation.
Two, the helicla flute on the processing roll:
(1) first spiral fluted processing:
According to roll spiral fluted spiral angle, the inclination angle of adjustment lathe tool 22, groove number, the cutting number of times of each groove, the lathe tool amount of feeding of input workpiece to be machined 25 on the display screen of lathe.Shifting slide gear 6 and fixed gear 7 are thrown off and idler gear 29 engagements.Shake planker radial feed crank 21, make lathe tool 22 contact workpieces 25.Start lathe, 18 rotations of radial feed servomotor drive is with 19 synchronously, is with 19 to drive leading screw 16 rotations synchronously, moves to radially zero-bit after leading screw 16 drives mother lead screw 17, upper slide rest 23, lathe tool 22.Main motor 1 starts, and main motor 1 is through first output shaft, 4 rotations of main reducing gear 2 driven gear casees 3, and first output shaft 4 drives workpiece 25 rotations that are installed on the workpiece chuck 26 through main spindle box 28; Gear-box 3 also drives differential left output shaft 5 simultaneously; Drive the right output shaft 9 of differential mechanism, feed rod 12 rotations through differential mechanism 8, feed rod 12 drives the rotation of planker gear-box 13 inner gear housings, and geared sleeve drives bevel-gear sett; 14 rotations of bevel gear driven gear axle; Gear shaft 14 and tooth bar 15 engagements that are fixed on the lathe bed 27, gear shaft 14 rotations drive planker 24 and on lathe bed 27, axially move, and planker 24 moves right to axial zero-bit.At this moment after lathe was had a break, beginning feed, planker 24 moved axially left, workpiece 25 rotations, carried out first spiral fluted feed for the first time cutting.Radial feed servomotor 18,1 counter-rotating of main motor after cutting finishes drive workpiece, lathe tool recurrence zero-bit, and after at this moment lathe was had a break, beginning feed, planker 24 moved axially left, workpiece 25 rotates, and carried out first spiral fluted feed for the second time cutting.So circulation is until accomplishing the cutting of first spiral fluted.After the cutting of first spiral fluted finishes, main motor counter-rotating, the servomotor counter-rotating drives lathe tool, workpiece recurrence zero-bit.
(2) calibration of workpiece:
During calibration, main motor 1 is motionless, and servomotor 11 drives decelerators 10, drives the right output shafts 9 of differential mechanisms, feed rod 12 rotations through differential mechanism 8, and feed rod 12 rotations drive the plankers 24 distance, delta L that moves right.When beginning second spiral fluted cutting, the distance, delta L because planker 24 has moved right has in advance just departed from distance of first helicla flute when lathe tool 22 touches workpiece 25, so just realized calibration.Need to prove that during calibration, differential left output shaft 5 does not change.
(3) second spiral fluted processing:
Beginning feed, planker 24 move axially left, workpiece 25 rotations, carry out second spiral fluted feed for the first time cutting.Radial feed servomotor 18,1 counter-rotating of main motor after cutting finishes; Drive workpiece, lathe tool are returned to the position that second helicla flute cuts beginning for the first time; At this moment after lathe is had a break; Beginning feed, planker 24 move axially left, workpiece 25 rotations, carry out second spiral fluted feed for the second time cutting.So circulation is until accomplishing the cutting of second spiral fluted.
(4) accomplish all spiral fluted processing on the roll:
The above-mentioned process of repetitive cycling (two), (three) can accomplish all spiral fluted processing on the roll.
