Description
Technical Field
[0001] The invention relates to the technical field of continuous casting machine roller processing, in particular to a continuous casting machine roller bearing seat disassembly and assembly equipment and a disassembly and assembly method thereof. Background Art
[0002] Each segment of the slab continuous casting machine has 30 sets of rollers, and each roller has two bearing seats with built-in bearings, with 24 segments per machine. The daily disassembly and assembly of the segment rollers is very heavy, and in the past, it has always been disassembled and assembled manually by knocking or pulling, which often affects the maintenance of the segment and is costly.
[0003] In the prior art, for example, the Chinese patent with application number 201120156237.0 discloses a disassembly and assembly device for a roller bearing seat of a fan-shaped segment, which relates to a rapid disassembly and assembly facility for a roller bearing seat of a fan-shaped segment of a slab continuous casting machine in the metallurgical industry. The technical scheme is: it includes an oil cylinder, a pull plate, a special pull sleeve, a roller clamp, and a stand. A pull plate is provided at the outer end of the oil cylinder rod, and a special pull sleeve is connected to the pull plate at one end and connected to the bearing seat at the other end, and matched therewith. A roller clamp is provided on the stand. The pull plate and the bearing seat are connected with a special pull sleeve, and the bearing seat can be disassembled and assembled by operating the hydraulic cylinder. This scheme realizes smooth hydraulic operation, avoids damage to the bearing by hammering, optimizes the fan-shaped segment preparation process, realizes batch continuous operation, improves the preparation quality, shortens the maintenance time, and reduces the labor intensity of workers. It has the characteristics of simple structure and convenient operation.
[0004] When the above solution is used, the roller can roll freely, and the roller is rolled between the disassembly and assembly power source, and the positioning is not accurate. If the roller is tilted, it will affect the stamping accuracy of the roller and the bearing seat, and may damage the workpiece; the roller rolls to the disassembly and assembly position and is stuck in position to prevent left and right movement. However, the roller is not centered and self-limited. During installation, the depth of the bearing seats on both sides entering the roller is inconsistent, which affects the subsequent installation and stable work. During disassembly, when one side of the bearing seat is removed, the stress state of the roller is destroyed, and the bearing seat on the other side is not easy to remove; in addition, the removed bearing seat is not easy to recycle, and there is a safety hazard of directly falling, thereby damaging the equipment.

[0030] A1. Evenly place the roller body with the bearing seat to be installed with the bearing in the arc-shaped placement grooves of multiple brackets, push the disassembly and assembly work frame to make it move intermittently on the top of the workbench, and stop when it is directly above the roller body with the bearing seat to be installed with the bearing;
[0031] A2. Insert the partial section of the bearing seat containing the bearing into the corresponding outer ring grooves on the top loading heads on both sides, then control the output ends of the hydraulic cylinders on both sides to extend synchronously, send the bearing seat containing the bearing to both ends of the roller body and pre-press it, so that the bearing seat containing the bearing is hung on the roller body. At this time, the roller body is centered and straightened;
[0032] A3. Control the output ends of the hydraulic cylinders on both sides to retract synchronously, separate the bearing seat containing the bearing from the top loading head, and control the pneumatic mechanism to extend the output ends of multiple cylinders synchronously, changing the inclination angle of the action plate until the force groove on its inner side or the pull rod installed on it can abut against the outer wall of the bearing seat containing the bearing, so that the thrust of the top loading head can act on the bearing seat containing the bearing, and at the same time, the force point does not contact the roller body;

[0036] B1. Evenly place the roller body of the bearing seat to be disassembled with the bearing in the arc-shaped placement grooves of multiple brackets, push the disassembly and assembly work frame to make it move intermittently on the top of the workbench, and stop just above the roller body of the bearing seat to be disassembled with the bearing.

[0044] 2. By setting the adjustment part, the working inclination angle of the action plate can be changed, and the action end of the pull rod can be adjusted on both sides of the bearing seat containing the bearing, so that it can be docked on both sides of the bearing seat containing the bearing, and it can be pushed or pulled to realize the installation and disassembly process of the bearing seat containing the bearing on the roller body.
