Installation structure of supporting bearing seat of steel plate shearing machine

The invention discloses an installation structure of a supporting bearing seat of a steel plate shearing machine. The installation structure of the supporting bearing seat of the steel plate shearing machine comprises a machine frame and the bearing seat, the machine frame is provided with a mounting groove and the bearing seat is arranged inside the mounting groove. The installation structure of the supporting bearing seat of the steel plate shearing machine is characterized in that a vertical plane is arranged on the lower portion of a side edge of the bearing seat, which is in the axial length direction of the bearing seat, a positioning key is further arranged inside the mounting groove and is located at the position of the outer side of the vertical plane, two sides of the positioning key, which are in the axial direction of the positioning key, and a mounting groove wall and the vertical plane are adhered to form tight-fit modes, and the positioning key is further provided with bolts which penetrate the positioning groove and the machine frame downwards to achieve fixation. The installation structure of the supporting bearing seat of the steel plate shearing machine has the advantages of being capable of ensuring the stability of the installation of the supporting bearing seat of the steel plate shearing machine and facilitating the dismantling of the supporting bearing seat of the steel plate shearing machine, and can ensure smooth production and improve the convenience of an overhaul.
