专利汇可以提供Gauge device for alignment of rolls of a rolling mill专利检索,专利查询,专利分析的服务。并且Device includes a gauge head mounted on a tube positionable in a horizontal plane along the centerline of a rolling pass of a rolling mill including two pairs of opposed rolls disposed around a common point in the center of the roll pass. Gauge head is disposed in the mill pass and is made up of four electrical probes each having a spring-loaded contact tip projecting a uniform distance from the centerline of the tube. The contact tips are spaced 90* apart around the periphery of the tube and each is engageable by the rolling surface of one of the four rolls forming the roll pass when the roll is moved toward the centerline of the roll pass to a predetermined distance away from the centerline of the roll pass for rolling a particular size workpiece. Each of the contact tips is connected through its respective probe to an indicator light in an electrical circuit which causes the respective indicator light to light up when the contact tip is touched by the rolling surface of the roll during alignment of the mill.,下面是Gauge device for alignment of rolls of a rolling mill专利的具体信息内容。

1. In a metal rolling mill having a pass formed by two pairs of opposed rolls in a mill housing, said rolls being positioned about a common point in said pass, the improvement therewith of gauge means for guiding alignment of said rolls relative to each other to adjust said pass to roll various sizes of workpieces, said gauge means comprising an elongated tube, means for supporting said tube in a horizontal plane along the pass centerline of the mill, four probes mounted on the portion of said tube in the center of said pass, said probes being spaced substantially 90* apart around said tube, a captive contact tip on the outer end of each of said probes each adapted to be contacted by one of said rolls, spring means in each of said probes constantly urging said contact tips outwardly, said probes being so dimensioned that the contact tips are each the same predetermined distance from the center of the tube, each of said probes being connected with an indicator and said indicators being connected with an electrical energy source whereby the indicator connected with a probe is actuated when the contact tip of the probe is touched by a roll being adjusted toward the centerline of the pass.
2. Apparatus as defined by claim 1 in which said means for supporting said tube includes a pair of upright support plates mounted on said mill housing one adjacent the entry end and one adjacent the exit end thereof, one of said plates having a cone affixed to the upper portion thereof extending normal thereto inwardly of the mill dimensioned to fit into and support one end of said tube, said cone being aligned with the centerline of said pass, the other of said plates having a gun sight post in its upper end fitting into a slot in the end of said tube opposite said one end, said other of said plates being adjustably mounted on said mill housing whereby proper positioning of said tube along the centerline of said pass is achieved by adjusting said last-named plate by visually aligning said cone and said gun sight post before said tube is placed in position.
3. Apparatus as defined by claim 1 in which each of said probes is surrounded by an electrical insulator around the portion thereof passing through the wall of said tube.
4. Apparatus as defined by claim 1 in which each of said indicators is an electric light, said lights being connected in parallel and cOnnected to said electrical energy source.
5. Apparatus as defined by claim 4 in which said lights are each a different color so as to readily indicate which probe contact tip is touched by its respective roll.
6. Apparatus as defined by claim 1 in which said probes are protected by a guard shield surrounding said portion of said tube, said guard shield having radial holes therethrough for passage of said contact tips therethrough.
