Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a magnetic measuring tool for a U-shaped seat of a continuous casting machine support frame. Background Art

[0002] When measuring the U-shaped seat of the continuous casting machine support frame, a sample shaft is required for measurement. For example, the prior art, such as the patent document with the publication number CN 209027456 U and the name of a slab continuous casting machine fan-shaped support measurement and reading tool, records that the device includes a through shaft, a cylindrical seat, and a positioning shaft head. The through shaft, the cylindrical seat, and the positioning shaft head are processed as a whole. The positioning shaft head is located at both ends of the through state, and the cylindrical seat is located on the outside of both ends of the positioning shaft head. The through shaft, the cylindrical seat, and the positioning shaft head are designed as concentric arcs. The advantage is that the detection position accuracy can be improved by 0.01mm, and the original method has about 8-10 data collection points for a single dummy shaft. Using the slab continuous casting machine fan-shaped support measurement and reading tool of this design, the single dummy shaft data collection point can be reduced to 2 times. When the tool is measuring the U-shaped seat in an inclined state, it cannot be in close contact with the bottom surface of the U-shaped seat due to the influence of gravity.

[0003] When the currently used dummy axis is used to measure a U-shaped seat in a non-horizontal state, the sample axis cannot be in close contact with the bottom surface of the U-shaped seat due to the effect of gravity, and the measurement personnel need to use tools such as gaskets to fix its position, which will cause a decrease in measurement accuracy.
