The present invention is a device that continuously measures the outer diameter as the outer diameter of the ring increases during the annular rolling process, by rotating the gas of the measuring instrument in the counterclockwise direction by a swing bar. It makes the work more convenient by reducing the space occupancy, and forms a roller body at the rear end between the disk supports, and three rollers precision-processed there are laid down using the principle of three-point stability. The objective of this paper is to make the work more convenient by rotating the swing bar to the side when attaching and detaching the specimen, unlike the conventional sliding type measuring instrument. It is much simpler in the structural design of the rolling mill and it is possible The purpose is to mitigate the impact moment at the rollers and to protect the device and to read the measured distance signal detected at the magnet scale at the digital readout accurately.

Conventional front and rear sliding type measuring device is fixed in the state that the aircraft is not rotated, and the disc support is also moved only before and after, so when the specimen is mounted on the rolling roller, it is limited in the space use of the upper surface of the rolling mill, which creates complexity in the work. When a shock is applied to the shock force, the impact force is directly transmitted to the magnet scale, which may shorten the life of the device, and there is a problem that the numerical value of the digital lead out cannot be read accurately.

Referring to the accompanying drawings, the present invention for solving the conventional problems as described above are as follows.

In the rolling mill 3 which mounts and rolls the ring-shaped specimen 2 between the rolling rollers 1 and 1a, the magnet scale 4 is mounted on the upper surface of the rolling mill 3 on the side where the outer diameter of the specimen 2 is increased. The swing bar 5 on the base bracket 6 with a pin 6a so that the swing bar 5 can be rotated by 90 ° counterclockwise and the fixing pin 6b. 6 rollers (8) (9) (10) (8a) which are precisely processed by horizontally stacking two round bars (7) (7b) under the swing bar (5). (9a) (10a) is arranged in the roller body 12 formed in the rear end of the disk support 11, the upper roller (8) (9) (8a) (9a) is located on the top of the round bar (7) (7a) Lower rollers (10) and (10a) are located on the lower surface of the round bar (7) (7a) and the upper rear rollers (8) and (8a) are arranged to flow in the recessed part (12a) of the upper rear part of the roller body The coil springs 14 and 14 are disposed at both ends of the upper and lower roller sides 13 and 13a. As a), it was pushed forward and backward while giving elasticity between up and down rollers.

In addition, the tension spring 15 is fixed to the rear side of the swing bar 5 so as to be guided by the spring guide roller 16 at the front end of the roller body 12, and the disk support portion is moved forward from the lower part of the roller body 12 to the front ( 11) extend the disk 17 at its end downward to the disk shaft 18 so that the disk 17 touches the outer circumferential surface of the specimen 2 so that the diameter of the specimen 2 increases. 12) was advanced back and forth so that the measurement of the magnet scale 4 was displayed on a separate known digital lead out, not shown.

As described above, the present invention can rotate the swing bar 5 in a counterclockwise direction, thereby widening the work space for mounting the specimen 2 to the rolling roller 1, 1a, and allowing for convenient operation, and the disk 17. If it is easy to fold the outer surface of the test piece 2 and an impact force is generated during rolling of the test piece 2, as shown in FIG. 6, the end of the disk support 11 is rotated and the rear end of the roller body 12 is lowered. The lower rollers 10, 10a are formed on the lower surface of the round bar 7, 7a by the coil springs 14, 14a coalesced between the upper rollers 8, 8a and the lower rollers 10, 10a. Since it is dropped and returned to its original position by the elastic force of the coil springs 14 and 14a, the magnet scale 4 is able to detect a signal that does not take an over-impact moment and does not change the measurement distance.

And between the upper roller (8) (9), (8a) (9a) and the lower roller (10) (10a) and the round bar (7) (7a), respectively, the tip of the disc support interval (11) according to the principle of three-contact stability. The force to be lowered is kept parallel to the contact of the upper roller (9) (9a) and the lower roller (10) (10a), and the excessive shock transmitted to the disc support section (11) is the upper, lower roller (8) (8a) Absorbed by the side of 10, 10a, the disk 17 always moves back and forth in accordance with the increased diameter distance of the specimen 2 at a stable position, and detects the detection signal of the correct measurement distance detected by the magnet scale 4. It can be read correctly in a separate digital lead out, not shown, installed with the magnet scale 4 and wiring. Therefore, the present invention, in the continuous measurement of the outer diameter as the outer diameter of the ring increases during the annular rolling process, the swing bar (5) can be rotated to the side when the specimen (2) attached and detached, so that the space occupancy can be reduced and convenient work is possible. In addition, it minimizes vibrations and errors that occur during operation and has the effect of making stable and precise measurements.
