The power side or end of the rolling mill or the roller refers to the side of the roller connected with the power shaft at the shaft end, and the opposite side or end is an operation side or end; the up and down directions are directed to a state where the roll is horizontally placed, and the following description will be given by taking this state as an example only. The rolling mill can be placed in a vertical mode of the roller to perform rolling.
As shown in figures 1 and 2, the automatic assembling device for the roll system of the rolling mill comprises a rolling mill frame 10 and an integrated roll system 20 which form a slip fit, a driving mechanism drives the integrated roll system 20 to move into the rolling mill frame 10 and is connected with a transmission shaft 30 at the end part of a roll, a first positioning pin 41 is arranged on an upright column of the rolling mill frame 10, and the first positioning pin 41 is inserted into positioning holes which are arranged on the integrated roll system 20 and the rolling mill frame 10 and are aligned with each other. The assembly of the integral roll system 20 can be completed in an operation room, firstly, the integral roll system 20 is conveyed to the operation side of the rolling stand 10 by the conveying mechanism, then the driving mechanism drives the integral roll system 20 to slide to the rolling center position of the rolling stand 10, the first positioning pin 41 acts to lock the integral roll system 20 and the rolling stand 10, and the whole process is full-automatic, simple and convenient, and high in reliability.
In order to ensure the sliding stability of the integral roller system 20 on the rolling stand 10, as shown in fig. 4, a sliding rail 11 is provided on the base of the rolling stand 10, the length direction of the sliding rail 11 is consistent with the axial direction of the rollers of the integral roller system 20, the inner side wall of the sliding rail 11 is an inclined surface inclined upwards, a convex strip is provided at the lower end of the integral roller system 20, and the inclined surfaces at the two sides of the convex strip and the inner wall of the sliding rail 11 are provided with inclined surfaces which are mutually attached to form the sliding of the sliding rail 11 in the length direction and the. The slide rail 11 is in contact-type movable fit with the raised line inclined plane, which not only can play a role of guiding the integral roller system 20, but also can effectively prevent the integral roller system 20 from generating a side-tipping accident in the moving process.
Further, the distance between the columns 12 at the feeding side and the discharging side of the rolling stand 10 corresponds to the position of the chock at both ends of the roller of the integral roller system 20, and a chamfer is arranged between the inner side wall and the outer side wall of the column 12 at the near side of the roller. The chamfer angle is arranged to play a role in guiding and supporting the integral roller system 20, so that the integral roller system 20 can be conveniently moved into the rolling mill stand 10; in order to provide a reliable moving gap, the distance between the outer side faces of the uprights of the operating side of the integrated roll system 20 is slightly smaller than the distance between the inner side faces of the uprights 12 of the operating side of the roll stand 10, and after normal assembly is completed, the gap between the outer side faces of the uprights of the integrated roll system 20 and the inner side faces of the uprights 12 of the same-end roll stand 10 is reserved for facilitating roll replacement.
Referring to fig. 3, after the flat head of the integrated roll system 20 is sleeved with the flat head hole at the shaft end of the transmission shaft 30, the transmission shaft 30 needs to move to the rolling center on the foundation a together with the integrated roll system 20 and the rolling stand 10, the bearing seat of the transmission shaft 30 is placed on the bracket 50, and when the positioning hole arranged at one side of the bracket 50 adjacent to the rolling stand 10 is aligned with the positioning hole at the corresponding position on the rolling stand 10, the bracket 50 and the rolling stand 10 are inserted by the second positioning pin 51, and the second positioning pin 51 acts to determine the position of each other.
Preferably, the first positioning pin 41 is a piston rod of the first positioning cylinder 411, and the second positioning pin 51 is a piston rod of the second positioning cylinder 511. The arrangement facilitates the installation and the disassembly of the rolling mill.
The position of the plane part of the flat head of the roller of the integrated roller system 20 is random in the transferring process, that is, the position of the plane part of the flat head of the integrated roller system 20 of the roller cannot be maintained in the horizontal direction, in order to ensure that the position of the plane part of the flat head is matched with the transmission shaft when the integrated roller system is matched with the flat head hole of the transmission shaft 30 in a plug-in mode, the flat head end of the integrated roller system 20 is provided with a flat head positioning mechanism 60, and a pressure plate of the flat head positioning mechanism 60 restrains the plane section of the flat head of the roller to be positioned in the horizontal plane, and the horizontal plane is upward or downward.
