With side be provided with movable block slide plate, the fixed block bottom and side be provided with fixed block slide plate, the movable block slide plate with it is described
Fixed block slide plate contacts with each other.
6. a kind of assembly method of external hydraulic cylinder work roll shifting device, it is characterised in that：For assembling claim 1 institute
The external hydraulic cylinder work roll shifting device stated, its step includes：
S1：Movable block is positioned on fixed block, after adjustment absolute altitude, the movable block is positioned over to the left lateral position on fixed block
Put；
S2：Hydraulic cylinder is passed through to the mounting hole of the fixed block right part, and the ring flange of the hydraulic cylinder is close to described
The groove of fixed block right side, rotates the hydraulic cylinder, " D " the shape vertical edge of the ring flange of the hydraulic cylinder with it is described solid
Determine the vertical edge alignment of block, the hydraulic cylinder is then fixed on the fixed block right-hand member with bolt；
S3：At the homalocephalus for the cylinder rod that the hydraulic cylinder is blocked using spanner, hydraulic cylinder cylinder head is connected to the cylinder of the hydraulic cylinder
At the screw thread of bar, the cylinder rod of the hydraulic cylinder is then arranged at fully retracted state；
S4：On the exterior circular column that pad is placed on to the hydraulic cylinder cylinder head, intermediate pads are placed on the hydraulic cylinder cylinder head left
Being risen to cardiac prominence for end, it is stand-by；
S5：In the blind hole that lower bolster is positioned over to the movable block, the cylinder rod of the hydraulic cylinder is pulled, makes the hydraulic cylinder
Cylinder head and the intermediate pads enter in blind hole, and described risen to cardiac prominence of the hydraulic cylinder cylinder head front end makes the lower bolster automatic
To the heart, untill dieback；
S6：The pad being placed on the hydraulic cylinder cylinder head external diameter is adjacent to the right side of the movable block, by end cap
Two parts are placed in the outer cylindrical body of the hydraulic cylinder cylinder head from both sides respectively, are then close to the pad, are tightened against with bolt
Note ensureing on the movable block, during installation between reserving suitably between the hydraulic cylinder cylinder head intermediate groove and the end cap
Gap, this gap is mainly adjusted by the thickness of the pad；
S7：Pipeline is respectively connected to the oil inlet and oil return mouthful of the hydraulic cylinder, work roll shifting function is realized.
7. the assembly method of external hydraulic cylinder work roll shifting device according to claim 6, it is characterised in that：Also wrap
Include following steps：
S8：In the normal operation of rolling of milling train, the slide plate between the movable block and the fixed block has abrasion, described to move
Motion block automatic aligning；
S9：When the cylinder rod holds out against the movable block again, the middle spacer and the hydraulic cylinder cylinder head are due to described right
Cardiac prominence rise and it is automatic with one heart.
