Description

Technical Field

[0001] The present invention belongs to the technical field of roller position adjustment, and in particular relates to a roller position adjustment indicating device and method. Background Art

[0002] During the steel rolling process, it is often necessary to adjust the position of the roll according to the needs of the production line. The working principle of the roll position adjustment device is as follows: the motor is connected to the worm, and the power is transmitted to the worm wheel, which drives the worm wheel to rotate. The inner side of the worm wheel is a trapezoidal thread pair. The worm wheel can only rotate and cannot move, and the lead screw inside the worm wheel can only move along the axis and cannot rotate, so that the lead screw matched with the trapezoidal thread inside the worm wheel drives the front vertical roller to move back and forth, and the position adjustment indicator device is connected to the motor through a gear set. As the motor rotates, the indicator device will also rotate to display the moving distance of the roll position.

[0003] The current roll position adjustment device has the following problems: when the vertical roll needs to be adjusted, the motor rotates. Because the transmission uses a worm gear and trapezoidal thread pair, these mechanical transmissions have a large transmission gap. This causes the motor to rotate, and the indicator device to rotate accordingly, but the roll does not move due to the transmission gap. The operator observes that the indicator device has rotated and mistakenly believes that the vertical roll has moved. As a result, the operator observes that the indicated displacement distance is greater than the actual roll displacement distance, reducing the roll position adjustment accuracy and affecting the product quality of the production line.

The worm wheel 5 is rotatably connected to the rolling mill support 2, and the worm wheel 5 is cooperatively connected to the worm 6. A trapezoidal thread is provided on the inner side of the worm wheel 5; the base 3 is fixedly connected to the rolling mill support 2.

[0045] The roller 1 is rotatably connected to the movable bracket 15 . The movable bracket 15 is fixed with a lead screw 7 that matches the trapezoidal thread. The lead screw 7 is cooperatively connected with the trapezoidal thread inside the worm gear 5 .

[0046] The side wall of the indicator plate 11 is provided with scale markings;

[0047] The base 3 is provided with an indicator mark corresponding to the scale mark.

[0048] The shift rod 16 is fixedly connected to the connecting rod 9 by bolts;
