Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for measuring the accuracy of the arc-shaped curved surface of a Naginata gauge used in continuous casting equipment.

As shown in FIG. 1, in a curved continuous casting equipment, a Naginata gauge 1 is used in contact with a centering reference surface 4 of a mold 2 and a slab guide roll 3 provided directly below the mold 2. It is a hollow-shaped measuring gauge having an arcuate curved surface 5 on one side of the blade.

Before using the gauge 1, it is necessary to measure the accuracy of the strain gauge 1 depending on the frequency of use, the state of accuracy maintenance, etc. Conventionally, as shown in FIG. Fix the prototype 7 and set the naginata gauge 1
The accuracy was measured by bringing the curved surface portion 5 of the sample into contact with the curved surface portion 7A of the prototype 7.

However, since the Naginata gauge 1, which measures accuracy by contacting it with the prototype 7 on the surface plate 6, is quite heavy, the friction caused by the surface contact with the surface plate is large, and the measurement is performed while simultaneously sliding the contact surface. This required an extremely large amount of labor and lacked workability.

The present invention aims to eliminate the above-mentioned drawbacks, and one embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 3 to 5, reference numerals 8 and 8 indicate prototype holding stands on which the prototype 7 is sandwiched so as to be fixed therethrough with fastening bolts 9.

Reference numeral 10 denotes guide columns erected at multiple locations on the upper part of the prototype holding table 8, and the guide columns 10 on the outside in the longitudinal direction are longer than the guide columns on the inside.

Note that 11 is a pusher screwed into the guide column 10.

Next, the operation of the present invention will be explained.

Place the Naginata gauge 1 on the curved surface IA of the prototype 7, bring the curved surface 5 of the Naginata gauge 1 into contact with the curved surface 7A, and measure the accuracy by sliding it along the arc in the direction of the arrow in the figure. .

Here, a gap is provided between the guide columns 10 and 10 arranged opposite each other to facilitate the sliding of the naginata gauge 1, and depending on the thickness of the naginata gauge 1, the guide columns 10 and 10
The sliding gap can be adjusted as desired by adjusting the gap formed between the two and the sliding gap with the push metal fitting 11.

Next, when the accuracy measurement of the curved surface portion 5 is completed, the Naginata gauge 1 is taken out, and the prototype 7 is stored with it attached to the prototype holder 8.

FIG. 5 shows another embodiment in which the roll 12 is attached to the guide column 10. The rolls 12, 12 installed opposite each other are attached, and the accuracy is measured by sliding the Naginaku gauge 1 against the prototype 7. Then, the sliding operation becomes easier and measurement can be performed more accurately.

As described above, according to the accuracy measuring device of the Naginata gauge for continuous casting equipment of the present invention, the frictional resistance between the Naginata gauge and the guide column can be reduced without sliding the Naginata gauge against the prototype on the surface plate as in the conventional method. The frictional resistance between the curved surface of the gauge and the curved surface of the prototype due to the Naginata Gauge's own weight causes sliding, which greatly improves work efficiency, and work can be done not only on the surface plate but also on any horizontal surface. In addition, the prototype holding stand can be placed vertically or horizontally.

Furthermore, while the prototype is being stored, it can be stored in a state where it is clamped to the prototype holding stand, so there are many remarkable effects, such as being able to store it with high precision without causing distortion.
