The utility model is achieved in that like Fig. 1 to shown in Figure 3; Its structure comprise frame, roll system and by the motor drives worm and wormwheel, drive housing screw again and move; And then promote the roll-separating mechanism that front-end bearing pedestal and roll move; The architectural feature of described roll-separating mechanism is to shown in Figure 3 like Fig. 1; With the left and right sides screw box 10,10 of left and right sides housing screw 11,11 ' match ' the rear end be equipped with respectively Y-axis to thrust rolling bearing 6,6 '; Its outside be separately installed with left and right sides annular bearing with rolling contact 7,7 '; Left and right sides housing screw 11,11 ' the lower end respectively with install before the left and right sides front-end bearing pedestal 14,14 ' contact of roll 15, left and right sides housing screw 11,11 ' the other end left and right sides worm gear 1,1 ' centre bore in axially slide, circumferentially fixing, be equipped with back roll 15 ' left and right sides rear bearing block 12,12 ' with left and right sides front-end bearing pedestal 14,14 ' between compress about being separately installed with spring 13,13 '; Its axis and left and right sides housing screw 11, the perpendicular servo-hydraulic oil cylinder 17 of 11 ' axis are installed in the frame centre position; The piston rod front end and the two-sided tooth bar 18 of servo-hydraulic oil cylinder 17 are rigidly connected, about two-sided tooth bar 18 respectively with left and right sides sector 16,16 ' engagement, left and right sides sector 16,16 ' right ends respectively with left and right sides screw box 10,10 ' for being fixedly connected.
The described roll-separating mechanism of the utility model is installed in the adjustment that can be used to align roll gap on the plate straightening roll frame.
Advantage of the utility model and good effect:
1, adopt elder generation through left and right sides motor driven in synchronism coarse adjustment roll gap, utilize the servo-hydraulic oil cylinder to carry out synchronously accurately adjustment roll gap again, the realization double precision is regulated roll gap, can regulate roll gap fast, accurately and reach required value.Both satisfied control accuracy, and can depress fast again, can make milling train, strip rolling-casting machine, plate straightening roll and the stable work of other pipe-mill.
2, adopt worm-drive and the screw box axial restraint, circumferentially rotatable that can realize self-locking, the two-sided tooth bar, the sector gear that connect through the servo-hydraulic oil cylinder can stop nut to rotate.Realize coarse adjustment and accurate adjustment respectively, though both mechanical parallel coupled, action is connected to be coordinated, not to have mutually and interfere.
3, adopt a servo-hydraulic oil cylinder to drive two-sided tooth bar and move back and forth, the left and right sides screw box that left and right sides sector gear rotates both sides simultaneously only rotates, and does not axially move; Driving left and right sides housing screw by left and right sides screw box axially moves; Realize synchronous accurate adjustment roll gap, improved reliability, simplified system; Guarantee precision, reduced cost.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the structure chart that is connected with housing screw.
Among the figure: 1,1 '-left and right sides worm gear, 2,2 '-left and right sides worm screw, 3,3 '-left and right sides shaft coupling, 4,4 '-left and right sides motor; 5,5 '-left and right sides support set, 6,6 '-Y-axis is to thrust rolling bearing, 7,7 '-left and right sides annular bearing with rolling contact, 8,8 '-left and right sides frame; 9,9 '-left and right sides flange gland, 10,10 '-left and right sides screw box, 11,11 '-left and right sides housing screw, 12,12 '-left and right sides rear bearing block; 13,13 '-about compress spring, 14,14 '-left and right sides front-end bearing pedestal, 15,15 '-the front and back roll, 16,16 '-left and right sides sector; 17-servo-hydraulic oil cylinder, the two-sided tooth bar of 18-, 19-clutch, 20-slip ring.
