Abstract

A device for precisely measuring the levelness of a plate straightening machine roller belongs to the technical field of plate straightening machine maintenance equipment and is used for precisely measuring the levelness of the plate straightening machine roller. According to the technical scheme, a measuring base frame is a rectangular box body, a plurality of sliding blocks are placed in the box body of the measuring base frame, the sliding blocks are in sliding fit with the inner wall of the box body of the measuring base frame, a vertical insertion hole is formed in the middle of each sliding block, a guide column on the upper portion of a measuring arm penetrates through the insertion holes of the sliding blocks, and two inclined measuring supporting arms are welded to the lower portion of the measuring arm. The two measuring support arms are clamped on the upper surface of a measured roller, the lower end of the dial indicator is fixedly connected to the upper surface of the measuring base frame, the head of the dial indicator is opposite to the upper end face of the guide column, and the two ends of the measuring base frame are respectively connected with a support. The levelness measuring device can realize accurate measurement of levelness of the working roller and the supporting roller of the straightening machine roller, is suitable for levelness measurement of roller surfaces with different roller diameters and roller intervals, can be used in a limited space, and provides measurement data for assembly adjustment and online detection.
