Description
Technical field
The utility model relates to a kind of mill rolls counterpart, particularly a kind of mill rolls adapting device for locating.
Background technology
At present, in cold-rolling mill production process due to the wearing and tearing of operation roll of mill, often to change working roll, but due to working roll and spindle in mating connection by flat spindle nose and flat axle sleeve, so when roll change, the parking spot of working roll and axle sleeve is extremely important, but generally, parking spot is uncertain during roll change, caused working roll after replacing, to need again centering location, operation and trouble thereof, affected production efficiency.
Summary of the invention
In order to address the above problem, the positioner while the utility model proposes a kind of mill rolls roll change.
Mill rolls positioner described in the utility model, comprise frame, frame inside is provided with roll bearing seat of rolling mill, along the axial rings of roll bearing seat of rolling mill, establish some locating pieces, the extension line of these some locating piece axis all intersects with the longitudinal center line of roll bearing seat of rolling mill, being fixed in frame of described locating piece extension type, and machine roll bearing seat is provided with the locating hole matching with locating piece.
Preferably, described locating piece comprises hydraulic cylinder and pillar, and hydraulic cylinder is fixedly installed in frame by support, and the piston rod in hydraulic cylinder is connected with locating hole coupling by pillar.
Preferably, described locating piece has two.
Preferably, described locating piece has three.
Mill rolls positioner described in the utility model, in roll bearing seat of rolling mill axial rings, establish some locating pieces, in the time of need to locating, several locating pieces are locating mill rolls from multiple directions of extension type simultaneously, and roll can stable and accurately be stopped, can not change position in any case, the utility model is simple in structure, and convenient operation has shortened roll changing time after effective location, improved operating efficiency, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-frame in figure; 2-roll bearing seat of rolling mill; 3-locating hole; 4-pillar; 5-hydraulic cylinder; 6-piston rod.
The specific embodiment
Embodiment 1
Mill rolls positioner described in the utility model, frame 1 inside is provided with roll bearing seat of rolling mill 2, along the axial rings of roll bearing seat of rolling mill 2, establish two locating pieces, the extension line of two locating piece axis all intersects with the longitudinal center line of roll bearing seat of rolling mill 2, described locating piece comprises hydraulic cylinder 5 and pillar 4, hydraulic cylinder 5 bodies are fixedly installed in frame 1 by support, and the piston rod 6 in hydraulic cylinder 5 bodies is connected with the locating hole 3 on bearing block by pillar 4.
Because locating piece described in the utility model has two, ring is located at roll bearing seat of rolling mill 2 both sides, on roll bearing seat of rolling mill 2, be provided with matchingly two locating holes 3, when milling train stops, in the process slowly stopping in mill rolls, by hydraulic cylinder 5, promote piston rod 6 and move, further drive pillar 4 to be inserted in the locating hole 3 on roll bearing seat of rolling mill 2, guaranteed that roll is stable and stopped accurately.
Embodiment 2
The present embodiment is substantially the same manner as Example 1, difference is that the locating piece described in the present embodiment has three, three locating pieces of the present embodiment setting encircle equably and are located at around roll bearing seat of rolling mill 2, and the present embodiment is selected three locating pieces, has more stable locating effect.
