Description
Technical Field
The utility model belongs to the technical field of steel rolling production line mechanical transmission carries technique and specifically relates to a split type roll table that can realize online maintenance.
Background
In a steel rolling production line, a roller way is widely used as conveying equipment, and the surface of the roller way is easily abraded due to the influence of frequent use and other degradation factors. If the worn roller way can not be replaced timely, the surface quality problem of a rolled piece can be caused or other production faults can be caused, the roller ways which are used in large quantity at present are mostly assembly parts of an integrally formed roller sleeve and a roller shaft, the roller ways are required to be integrally replaced and offline when maintenance is needed, the operation time is long, and the production efficiency is influenced. In addition, when the roller way is maintained under the line, the bearing seat, the bearing, the coupler and the like need to be removed firstly, then the roller sleeve can be replaced, and the labor cost is wasted due to long time of the maintenance operation under the line.
Therefore, how to maintain and replace the online abrasion roller way in time and improve the production operation efficiency becomes a problem to be solved urgently in the technical field.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to carry out online maintenance treatment on the abrasion roller way improves the production efficiency and reduces the maintenance cost.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model discloses a can realize online maintenance's subdivision formula roll table, include: a roll shaft; the two semicircular sleeves are embedded and connected and are sleeved on the roll shaft to form a roll sleeve; and the movable chuck is in threaded connection with the roll shaft and is in embedded connection with two end faces of the roll sleeve to limit the separation of the two semicircular sleeves.
How to prevent that the axis of activity chuck on the roller from removing, the utility model discloses a go back threaded connection on the roller and have the nut, the nut with the outer terminal surface of activity chuck offsets.
How to restrict the rotation of roller cover on the roller, the utility model discloses a semicircle sleeve pipe with the roller is provided with spacing key.
How to limit the two semicircular sleeve sleeves to be sleeved on the roller shaft for separation, the utility model adopts the structure that the end surfaces of the two ends of the two semicircular sleeve sleeves are both provided with limiting grooves; the inner wall of the movable chuck is provided with a bulge matched with the limit groove.
How to realize the positioning connection of the two semicircular sleeves, the utility model adopts the connecting surface of the semicircular sleeves to be respectively provided with a strip-shaped groove and a lug boss; the strip-shaped groove is matched with the boss surface of the other semicircular sleeve; the boss is matched with the strip-shaped groove of the other semicircular sleeve in shape.
The utility model has the advantages that: the utility model discloses a can realize the subdivision formula roll table of online maintenance, the roller shell that can conveniently dismantle that this scheme utilization set up has realized when the roll table wearing and tearing need be changed, directly carries out the roller shell on the line and changes, need not whole roll table and dismantles the maintenance, this novel device easy dismounting effectively improves maintenance personal work efficiency, has practiced thrift manufacturing cost.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a front view of the roll shaft of the present invention;
fig. 3 is a left side view of the semicircular casing of the present invention;
FIG. 4 is a side view of the semi-circular sleeve shaft of the present invention;
FIG. 5 is a front view of the removable chuck of the present invention;
FIG. 6 is a right view of the movable chuck of the present invention
In the figure: 1. the roller comprises a roller shaft 11, a protrusion 12, threads 2, a split roller sleeve 21, a limiting groove 22, a line groove 23, a boss 3, a movable chuck 4, a nut 5 and a limiting key.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1 to 6, a novel split roller way capable of realizing online maintenance includes: the roller shaft 1 is provided with a main body of the roller shaft 1 which is a stepped shaft and is used for supporting the roller way to rotate; the roller sleeve 2 is sleeved on the roller shaft 1 and comprises two semicircular sleeves which can be embedded and connected; the movable chuck 3 is sleeved on the roller shaft 1 through a threaded connection 12 and is in embedded connection with the end part of the roller sleeve 2; the nut 4 is arranged on one side of the movable chuck 3, and is tightly connected with the roll shaft 1 and the movable chuck 3.
The roller shaft 1 is connected with the semicircular sleeve in a positioning way through the arranged limit key 5, the inner side of the movable chuck 2 is convexly provided with a bulge 11 which is embedded and connected with a limit groove 21 on the end surface of the roller sleeve 2, and a thread 12 is arranged to be matched and connected with the movable chuck 3 and the nut 4; the axial movement of the roller sleeve 2 relative to the roller shaft 1 is prevented through the arranged limit key connection.
The end surfaces of two sides of the roller sleeve 2 are respectively provided with a limiting groove 21 which is embedded and connected with the bulge 11 of the movable chuck 3, and the splitting surface of the roller sleeve 2 is provided with a strip-shaped groove 22 and a lug boss 23, so that the positioning connection of the two semicircular sleeves is realized; the two semicircular sleeves are prevented from being separated from the roller shaft 1 by the embedding of the limiting grooves 21 and the chuck bulges 11, and the embedded connection between the two semicircular sleeves is realized by the arrangement of the line grooves 22 and the bosses 23.
After the device is used online, if the roller way is worn and needs to be replaced, the nut, the movable chuck and the roller sleeve are separated only by using a simple tool online, the two semicircular sleeves are knocked by using the tool to be separated from the embedded state, the roller sleeve can be replaced, the roller way is not required to be integrally taken off, and a large amount of maintenance operation time is saved.
The novel subdivision formula roll table that can realize online maintenance of this embodiment utilizes the convenient roller shell of dismantling that sets up, has realized when the roll table wearing and tearing need be changed, directly carries out the roller shell on the line and changes, need not whole roll table and dismantles the maintenance, and this novel device easy dismounting effectively improves maintenance personal work efficiency, has practiced thrift manufacturing cost.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
