Fig. 2 is that figure cuts open in the left side office of looking of Fig. 1;
Fig. 3 is Fig. 2 A-A cutaway view;
Fig. 4 is a B portion enlarged diagram among Fig. 2.
As Fig. 1,2, metal (upper seat 8 of the present utility model, in the gudgeon slide block mechanism on 9 two sides, the two ends of each gudgeon 22 are cylinder, its middle part is a flange arrangement, one end cylinder of each gudgeon 22 is respectively with last, step 8,9 obverse cylindrical hole does to cooperate the location, by flange by securing member with each gudgeon 22 and bearing block 8 separately, 9 fixed be one, all be set with slide block 23 on the other end cylinder of each gudgeon 22, the profile of slide block 23 is a square body, two sides at this square body one end are provided with positioning boss, slide block 23 is arranged in the chute of slide 24, and the two sides of slide block 23 are that machinery cooperates with the chute face of corresponding slide 24, each slide 24 is positioned on the concave station rank of supporting base 13 upper and lower sides, the corresponding surface on its side and supporting base 13 concave station rank is accurate the applying, the corresponding surface of its another side and box bed 14 is fitted (not containing each slide 24 that is positioned at supporting base 13 upper surfaces) for accurate, slide 24 is located by connector 25 with supporting base 13, affixed with securing member, each slide 24 upper end is equipped with slide lid 26, can stud with removable abrasion-proof backing block between the mating surface of slide 24 and slide block 23.The utility model is in roll roller pastern divides, fixedly bung flange 11 is fixed on the outer face of top chock 8 of the non-transmission side of milling train, its inner and axial screw rod 10 of adjusting is for being threaded, axially be fixed with dive key 27 on overhanging section the diameter of adjustment screw rod 10, and the worm gear set load of paying in 28 with worm and gear connects, worm and gear pays that the aperture of worm gear is provided with the dive key groove in 28, its shell and fixedly the faying face of bung flange 11 be provided with step location, and fix as one, the end of its worm screw is equipped with adjusting handle 29, axially adjusts to be connected with on the outer face of screw rod 10 and adjusts indicating dial 30.
Roll roller of the present utility model system adopts four pull bars 12 will have totally four of upper and lower bearing block 8, the 9(of very big rigidity) be bound up, rotating tension bar 12 can be realized the symmetry adjustment of roll 5.Usually before work, carry out the radially adjustment (also claiming to depress adjustment) and the axially adjustment of roll earlier, radially adjust and to finish by rotating handwheel 4, also but starter motor 31 is finished, motor 31 has deceleration device, it links to each other with the worm screw of worm gear case 1 in the hold-down transmission device, like this when rotating handwheel 4 or starter motor 31, transmission by worm gear case 1 makes each pull bar 12 rotate, the top of each pull bar 12 and lower end are provided with positive left-hand thread, top by separately when then its rotates and lower end radially guiding mechanism make roll 5 make up and down symmetry to adjust, obtain desired work roll gap.Roll mandrel is when adjusting, rotate adjusting handle 29, pay 28 transmissions by worm and gear, drive and axially adjust screw rod 10 rotations, owing to axially adjust screw rod 10 and fixing bung flange 11 for being threaded, relative fixed bung flange 11 moves axially when then adjusting screw rod 10 rotations, thereby fix by the thrust bearing 7 of thrust bearing 7(roll 5 non-transmision ends on the non-transmission side topping roll 5, and the thrust bearing 7 of its driving end moves about), and utilize the rolling element and the relatively-movable characteristics of its inner ring of journal bearing 6, driving roll 5 moves axially, finish the axial adjustment of roll 5, its adjustment amount can be controlled by the scale of adjusting on the indicating dial 30, and axially the purpose of adjusting is to be used for aiming at hole slot, makes the pass of top and bottom rolls 5 have relative position accurately.
In the utility model work, when rolled piece is sent into the pass of roll 5 by raceway, roll 5 bears rolling load can produce certain deflection deformation (strain), because the journal bearing 6 that is contained on the roller neck itself does not have the aligning effect, then in order to guarantee that the load on the journal bearing 6 is evenly distributed, just must make, step 8,9 make trace with the distortion of roll 5 around initial point separately floats, because it is last, step 8, all be fitted with the gudgeon slide block mechanism on the two sides of 9 roller diameter direction, then go up, step 8,9 do to rotate relative to trace around slide block 23 by gudgeon 22 separately when floating, and bear the axial load of roll 5 by being fixed on slide 24 on the supporting base 13, adopt on the work faying face between each supporting base 13 and the box bed 14 roll mandrel to the machinery location, and adopt securing member fastening, make the axial force of roll 5 finally be passed on the box bed 14, guarantee that roll 5 is last, step 8,9 do not have axial float when floating.Because it is last, step 8,9 when floating, each pull bar 12 should not float as complete machine positioning supports body, then pull bar 12 tops and lower end radially the adjustment nut 15 in the guiding mechanism also should keep motionless, removing relative pull bar 12 moves up and down, so close-fitting is last, step 8, latch 20 on 9, must and adjust between the square groove bottom surface on the nut 15 and leave gap 33(such as Fig. 3), like this, on can satisfying, step 8,9 is unsteady with roll 5, can guarantee to adjust nut 15 again with last, step 8,9 do not relatively rotate, thereby finish the function of radially adjusting.Each is the spring conductor rod 19 in the guiding mechanism radially, one end cooperates with balance nut 17 machineries, the spherical surface body of the other end is close to end cap 21(such as Fig. 4), be when floating for upper and lower bearing block 8,9, guarantee the balanced equilibrant force of balancing spring 18 outputs, with the gap between contact-making surfaces such as elimination pull bar 12 and adjustment nut 15, thus the rolling rigidity of raising milling train.The middle part of each pull bar 12 all is set with dissection type supporting base 13, in the breach of supporting base 13 side between corresponding metal ( upper seat 8,9, and and remain certain interval up and down between the inner surface in the breach, and fit with the medial surface of breach is accurate, the outside of the upper and lower end face of supporting base 13 preferably all is provided with the concave station rank.Pull bar 12 by with the cooperating and step location of supporting base 13, fit by the precision of slide 24 in concave station rank outside supporting base 13 upper and lower sides and the gudgeon slide block mechanism again, and slide 24 is fitted with the precision of box bed 14, make that this maintenance when upper and lower bearing block 8,9 floats with roll 5 of pull bar is motionless, finish the support function of milling train complete machine, guarantee the precision positioning of roll roller system.
The support navigation system that the roll roller that the utility model is made of the slide 24 in pull bar 12, supporting base 13, box bed 14 and the gudgeon slide block mechanism is, when upper and lower bearing block 8,9 floats with roll 5, both guarantee the precision positioning that whole roll roller is, satisfied the free degree that upper and lower bearing block 8,9 floats with roll 5 again.
In the utility model, be provided with a resilient protection frame 32 in the lower end of worm gear case 1, it is to impact connecting axle 2 when being used for preventing the arch of rolled piece accident, to guarantee the operating accuracy and the reliability of hold-down transmission device.
Supporting base 13 of the present utility model can be finished by rolling bearing or slide bushing with cooperating also of pull bar 12.Between the medial surface of supporting base 13 and upper and lower bearing block 8,9, preferably stud with removable abrasion-proof backing block, to prolong their service life.
