(54) DEVICE FOR MEASURING DIAMETER OF RINGS FROM ELASTIC MATERIAL

(57) The invention relates to a measurement technique. The purpose of the invention is to expand the range of measurable rings and

improving the reliability of the device due to the fixation of the ring on the measuring roller. The measuring roller 1 of the device is made with a flange 10. The roller 5 of the pressing mechanism is made with a flat stop 6 at the end with the possibility of placing the stop 6 on the size of the diameter of the section of the measuring ring 13. The roller 7 has the shape of a truncated cone, the smaller base of which faces the flange 10. The flat stop 6, the sensor 2 and the roller 7 of the clamping mechanism are installed along the movement of the ring 13, respectively, one after another. When moving the ring 13, its stable position relative to sensor 2 is ensured. 3 Il.

The invention relates to mechanical engineering, in particular to instrumentation technology, and can be used to measure the diameters of sealing rings of elastic material.

The aim of the invention is to expand the range of measurable rings and increase the reliability of the device by fixing the ring on the measuring roller. FIG. 1 shows a schematic of the proposed device; in fig. 2 is a view A of FIG. 1; in fig. 3 shows a section BB in FIG. 1. A device for measuring the diameters of rings of elastic material contains a measuring roller 1, a sensor 2 determining the turning moment of a measuring ring on the measuring roller one revolution, a drive 3 of the measuring roller 1, a counter 4 revolutions of the measuring roller 1 and a pressing mechanism having a roller 5 s flat stop b at the end and the roller 7. The roller 5 is mounted on the rod 8, and the roller 7 - on the axis 9. The measuring roller 1 has a flange 10, and the roller 5 has a pin 11 l screw 12.

The flange 10 serves to limit the movement of the measuring ring 13 on the landing roller 1 in one of the axial directions, and the flat stop 6 to limit the movement of the ring in the other direction. The roller 7 has the shape of a truncated cone and is mounted on the axis 9 with the apex toward the flange 10 of the measuring roller 1. Such a roller allows the measured ring to interact with the diameter and rim of the measuring roller, which reduces the likelihood of ring slip on the roller L creates conditions for increasing the speed - no measuring roller, and therefore the performance of the device. The pin 11 is located in the groove 14 of the rod 8 and serves to orient the flat stop 6 relative to the measuring roller 1 when the roller 5 moves along the axis of the rod. The screw 12 serves to fix the roller 5 on the rod 8 after adjusting the flat stop to the dimension d of the cross section diameter of the measuring ring 13.

The device works as follows.

In the initial position, the roller 5 with the flat stop 6 and the roller 7 are retracted to the non-working position. A measuring ring 13 is placed on the measuring roller 1, on the surface of which a label 15 is preliminarily applied. The counter is set to 4 turns to zero. The roller 5 with a flat stop 6 and the roller 7 is lowered into the working position and provide with the help of the roller 7 clamp

the measured ring 13 to the roller 1 and the flange 10. The drive 3 is turned on and the roller 1 is informed of the rotational movement. In this way, the surface of the monitored ring 13 moves relative to sensor 2. At the moment

passing the mark 15 in front of the sensor 2, the latter turns on the counter 4. When turning the ring 13 one turn, the mark 15 again passes in front of the sensor 2, which turns off the counter 4.

On the display of the counter 4, the diameter of the measured ring 13 is fixed. The roller 5 with the stop 6 and the roller 7 is retracted and the ring 13 is removed from the roller 1.

The constructive implementation of the device allows it to expand its technological capabilities by measuring rings having a distorted shape, burrs and sizes of diameter greater than 1300 mm, as well as

increase reliability by ensuring sustainable movement of the ring with a tag in front of the sensor, increase the range of tested rings, improve performance and simplify equipment for

heat-setting large diameter rings, as there is no need for large-sized heat chambers.
