ル幅を測定する装置に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for measuring a roll width of a roll having a function of arbitrarily adjusting the roll width of a horizontal roll in a universal mill applied to rolling of H-section steel or the like. is there.

実開平３−３１００１号公報にて提案している。2. Description of the Related Art A so-called variable width horizontal roll in which the width of a horizontal roll is adjusted in accordance with each dimension when rolling H-beams of different types has been proposed. Also, as shown in FIG. 6, a device for automatically adjusting the roll width of the horizontal roll online is proposed in Japanese Utility Model Laid-Open No. 3-31001.

2 is a width adjusting sleeve, 3 is a movable roll side inner screw, 4 is a width adjusting sleeve side outer screw, 5 is an arbor, 6 is a high pressure oil introduction hole for releasing the roll gripping force, 7 is a chock, 8 is a clutch mechanism, 9 Is a stopper, 10 is a fixing lever, 11 is a thrust receiver, 12 is a fixing bolt, and 13 is a fixing roll.

幅調整が実現する。In such a structure, when adjusting the roll width, first, oil is fed from the high-pressure oil introduction hole 6 to reduce the force of grasping the shrink fit between the movable roll 1 and the arbor 5, and then adjust the width with the arbor 5. When the width adjusting sleeve 2 is connected to the chock 7 side by the fixing lever 10 and fixed, the movable roll 1 is moved in the axial direction by applying a rotating force to the arbor 5 by removing the fixing bolt 12 with which the sleeve 2 is integrated. The required width adjustment is realized.

によって測定していた。By the way, the dimension after the width adjustment in such a variable width horizontal roll is obtained by detecting the number of rotations of the width adjusting sleeve side external screw 4 and converting the screw pitch to obtain the moving amount of the movable roll 1. The outer width dimension of the movable roll 1 and the fixed roll 13 actually moved was measured by a method, such as a method in which an operator actually enters the mill and measures as shown in FIG.

作業能率の面で問題がある。However, the conversion from the rotational speed of the width adjusting sleeve-side outer screw 4 leaves a problem in the measurement accuracy due to the backlash and pitch error of the screw. In addition, in actual dimension measurement in the mill, the mill must be stopped every time, and there is a problem in terms of safety and work efficiency.
