Description
Technical field
The utility model relates to a kind of locking device of cross rolling mill roll.
Background technology
As Fig. 1 and 2, at present, the roll of cross rolling mill is operationally in order to prevent axial float, retaining mechanism is devised to the bearing block of back up roll, this retaining mechanism comprises roll 1, bearing block 2, jam plate 3 and oil cylinder 4, the two ends of roll 1 are arranged on bearing block 2, are separately installed with described jam plate 3 in the draw-in groove of the both sides of bearing block 2, and each jam plate 3 is connected with a described oil cylinder 4.By the clamping force that two oil cylinders 4 produce, to bearing block clamping, thus prevent roll axial float.
For cross rolling mill, because topping roll and bottom roll are arranged crosswise, the angle that topping roll and bottom roll intersect needs to adjust with the situation of plate shape, require that the retaining mechanism of bearing block can pin roll axial float like this, the angle of bearing block can be allowed again to acquire change, the intersecting angle of topping roll and bottom roll just can be made to acquire change.But, though above-mentioned retaining mechanism can play the effect preventing bearing block axial float, but when topping roll and bottom roll intersect, because bearing shaft is clamped by two oil cylinders, the angle of two bearing blocks cannot be allowed to acquire change, restart cross rolling mill work after needing to adjust to the intersecting angle of needs under production line halted state, in the intersecting angle process adjusting topping roll and bottom roll, this retaining mechanism reduces directly causing production efficiency.
Summary of the invention
The new object of this practicality is the locking device providing a kind of cross rolling mill roll, and locking device of the present utility model can pin roll axial float, can allow again the effect that the intersecting angle of topping roll and bottom roll acquires change.
The technical scheme solved the problems of the technologies described above is as follows:
The locking device of cross rolling mill roll, comprise jam plate, also comprise bearing cover, thrust block seat, connecting rod and roller, the two ends of bearing cover are respectively equipped with groove, described thrust block seat is arranged in the groove that bearing cover is arranged, first end and the bearing cover of thrust block seat are hinged, the second end relative with first end of thrust block seat reaches described groove outside, the end of described connecting rod and the second end of thrust block seat hinged, the side of described thrust block seat is provided with the extension extended along bearing cover length direction, roller is hinged on extension, the circumference of roller is clamped by the other end of described jam plate.
Also comprise an oil cylinder, the piston rod of this oil cylinder is fixedly connected with jam plate.
The surface of described bearing cover SCCP connection-oriented bar is provided with baffle plate, and the end that connecting rod is connected with thrust block seat is provided with the limited block extended to bearing cover, between baffle plate and limited block, be provided with spring.
The utility model defines a parallelogram by bearing cover, thrust block seat, connecting rod, the thrust sent when roll intersects is on bearing cover, parallelogram is stressed and deformation occurs, and roll carries out intersection adjustment just without the need to stopping production line online according to the situation of plate shape.By the clamping force that jam plate pair roller is formed, four angles of parallelogram when deformation still keep motionless at initial point, locking device entirety cannot move at axial direction, serve locking device and can pin roll axial float, the effect that the intersecting angle of topping roll and bottom roll acquires change can be allowed again.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Detailed description of the invention
With reference to Fig. 3 to Fig. 6, the locking device of cross rolling mill roll of the present utility model, comprises jam plate 2, bearing cover 3, thrust block seat 4,4 ＇, connecting rod 5 and roller 6.The two ends of bearing cover 3 are respectively equipped with groove 31, and stretch out at the two ends of bearing cover 3 and form support arm 33, the space between two support arms and bearing cover 3 defines described groove 31.Certainly, also directly can cut on bearing cover 3, obtain described groove 31.Described thrust block seat 4,4 ＇ is arranged in the groove 31 that bearing cover 3 is arranged, thrust block seat 4, and the first end 41 of 4 ＇ is hinged with bearing cover 3.The second end 42 relative with first end 41 of thrust block seat 4 reaches described groove 31 outside, the end of described connecting rod 5 and thrust block seat 4, the second end of 4 ＇ is hinged, like this, with bearing cover 3, thrust block seat 4,4 ＇ and connecting rod 5 define a parallelogram, due to bearing cover 3, thrust block seat 4,4 ＇ and connecting rod 5 connection are each other hinged, therefore, the thrust sent when roll 9 intersects is on bearing cover 3, and parallelogram is stressed and deformation occurs.Like this, roll 9 carries out intersection adjustment just without the need to stopping production line online according to the situation of plate shape.
The side of described thrust block seat 4,4 ＇ is provided with the extension 7 extended along bearing cover length direction, and roller 6 is hinged on extension 7, and roller 6 is by hinge on extension 7, and like this, roller 6 freely can rotate around bearing pin.The circumference of roller 6 is clamped by the other end of described jam plate 2, after roller 6 is clamped by jam plate 2, roller 6 still can turn round centered by lock shaft, but because left and right (from figure) two rollers 6 have all been subjected to axial clamping force, cause locking device entirety cannot move at axial direction.Therefore, when by bearing cover 3, thrust block seat 4, during the parallelogram generation deformation that 4 ＇ and connecting rod 5 form, under the clamping force that jam plate 2 pair roller 6 is formed, four angles of parallelogram still keep motionless at initial point, locking device entirety cannot move at axial direction, serves locking device and can pin roll axial float, can allow again the effect that the intersecting angle of topping roll and bottom roll acquires change.The surface of described bearing cover 3 SCCP connection-oriented bar 5 is provided with baffle plate 32, and the end that connecting rod 5 and thrust block seat 4,4 ＇ connect is provided with the limited block 51 extended to bearing cover 3, is provided with spring 8 between baffle plate 32 and limited block 51.When parallelogram deforms, spring 8 is compressed, and when not having contention effect power, spring 8 resets and makes parallelogram be returned to reset condition.
In addition, the utility model also comprises an oil cylinder 1, and the piston rod of this oil cylinder 1 is fixedly connected with jam plate 2.By the active force that oil cylinder 1 pair of jam plate 2 produces, the chucking power that jam plate 2 pair roller 6 is produced obtains and ensures.When roll 9 needs to change, drive jam plate 2 to move by oil cylinder 1, cancel the clamping of pair roller 6, so that breaker roll is changed.
