Summary of the invention
The present invention is directed to the problems referred to above, a kind of screw mandrel bindiny mechanism of large-tonnage turning rolls is provided, this mechanism links into an integrated entity two rhizoid bars, can cut down finished cost, and guarantees the accuracy of alignment of roller.
According to technical scheme of the present invention: a kind of screw mandrel bindiny mechanism of large-tonnage turning rolls, the left screw mandrel and the right screw mandrel that comprise coaxial arrangement, described left screw mandrel and described right screw mandrel are connected by shaft joint, described shaft joint comprises first ladder axle and second ladder axle by the securing member connection of axial subdivision, the connection axle head of described left screw mandrel and described right screw mandrel is respectively arranged with annular groove, be provided with the bulge loop that matches with described annular groove in the axis hole of described shaft joint, described annular groove is connected by key with described bulge loop.
Described annular groove is connected by flat key with described bulge loop.
The junction of described first ladder axle and described second ladder axle is respectively arranged with axial semicylindrical opening, be respectively arranged with corresponding two semi-convex rings in two described axial semicylindrical openings, have keyway on described two semi-convex rings of described first ladder axle.
The junction of described first ladder axle and described second ladder axle is provided with flange, has screwed hole on the flange of described first ladder axle, has through hole on the flange of described second ladder axle, and connects by soket head cap screw.
Technique effect of the present invention is: the present invention connects two rhizoid bars by shaft joint, transmits moment of torsion by key, and the axial force that the step by the shaft joint internal projecting ring comes the balance screw mandrel to produce has reduced the difficulty of processing of screw mandrel, has also improved the screw mandrel precision simultaneously; Two rhizoid bars by a Motor Drive one had both improved the roller accuracy of alignment, had improved operating efficiency again, had also reduced cost simultaneously; The present invention is simple in structure, keeps in repair easy to assembly.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1～Fig. 5, comprise turning rolls base 1, left screw mandrel 2, left wheel 3, right roller 4, right screw mandrel 5, motor 6, flat key 7, first ladder axle 8, semi-convex ring 9, annular groove 10, soket head cap screw 11, second ladder axle 12, keyway 13, semicylindrical opening 14, screwed hole 15, through hole 16 etc.
As shown in Figure 1, be a kind of large-tonnage turning rolls, left wheel 3 and right roller 4 are installed on turning rolls base 1.Left screw mandrel 2 and right screw mandrel 5 are installed in the turning rolls base 1, and left screw mandrel 2 is opposite with right screw mandrel 5 rotation directions, the screw that has been threaded respectively, and two screws are fixedlyed connected with left wheel 3 and right roller 4 respectively.Left side screw mandrel 2 and right screw mandrel 5 coaxial arrangement are connected by shaft joint, and the outer end of right screw mandrel 5 links to each other with motor 6.Rotating by motor 6 drives left screw mandrel 2 and 5 rotatings of right screw mandrel, and and then the centre-to-centre spacing that drives left wheel 3 and right roller 4 increase or reduce, thereby adjust the centre-to-centre spacing of two rollers.
As Fig. 2, shown in Figure 3, above-mentioned shaft joint comprises first ladder axle 8 and second ladder axle 12 by the securing member connection of axial subdivision, the connection axle head of left side screw mandrel 2 and right screw mandrel 5 is respectively arranged with annular groove 10, be provided with the bulge loop that matches with annular groove 10 in the axis hole of shaft joint, annular groove 10 is connected by key with bulge loop.Preferably be connected between annular groove 10 and the bulge loop by flat key 7.
As Fig. 4, shown in Figure 5, the junction of first ladder axle 8 and second ladder axle 12 is respectively arranged with axial semicylindrical opening 14, be respectively arranged with in two axial semicylindrical openings 14 on two semi-convex rings 9 of corresponding two semi-convex ring 9, the first ladder axles 8 and have keyway 13.Form step between semicylindrical opening 14 and the semi-convex ring 9.
The junction of first ladder axle 8 and second ladder axle 12 is provided with flange, has on the flange of first ladder axle 8 on the flange of screwed hole 15, the second ladder axles 12 and has through hole 16, and connect by soket head cap screw 11, referring to Fig. 3.
Assembling process of the present invention is as follows: earlier left screw mandrel 2 and 5 alignment of right screw mandrel are set level, then flat key 7 is contained in respectively in the keyway of two rhizoid bars, first ladder axle 8 is contained on the two rhizoid bars blocks, then with second ladder axle 12 by last, it is tightened fixing by soket head cap screw 11 at last.
