Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of detection, and specifically relates to a large-diameter ring piece inner diameter ovality detection device. BACKGROUND

[0002] With the development of domestic heavy industry, the application of large-diameter ring pieces is gradually increased in the fields of nuclear power, military industry, petrochemical industry, energy, and shipbuilding, and such ring pieces are usually integrally hot formed by forging or ring rolling, and have the characteristics of no longitudinal weld, large diameter, large wall thickness, large height, and high dimensional accuracy. In the manufacturing process of large-diameter ring pieces, whether it is the forging or ring rolling process, or the heat treatment or machining process, the size of the ring piece needs to be measured to determine the ovality of the ring piece at different height positions, thereby providing data support for the size control of the subsequent process.

[0003] The commonly used size measurement methods include a tape measure, a micrometer, a marking platform, a laser tracker, a total station, and a numerical control vertical lathe dotting. When the diameter of the ring piece exceeds 6 meters, or even reaches 16 meters, and the height is 2 meters to 5 meters, the tape measure, the micrometer, and the marking platform cannot realize the measurement of the ovality of the ring piece at different height positions. Although the laser tracker and the total station can obtain ideal data, they have the disadvantages of complex operation, the need for post-processing software, high equipment cost, and the ability to only measure at room temperature, and thus cannot realize the rapid measurement of the ring piece and have a heavy economic burden on small and medium-sized enterprises. The numerical control vertical lathe dotting can also obtain ideal data, but has the disadvantages of occupying equipment time and being able to only measure at room temperature, and thus cannot meet the requirements of batch industrial production.

[0048] In the embodiment, the rotating gear 20-2 is further provided with a rotating angle detection device 29; the rotating angle detection device 29 is in communication connection with the first processor 25, and the first processor 25 obtains the rotating angle detected by the rotating angle detection device 29 and sends the obtained rotating angle to the remote controller 28 for display through the wireless communication module 26.

[0050] The first motor 6, the second motor 12, the third motor 23 and the fourth motor 20-4 are all servo motors, and the wireless communication module is a Bluetooth wireless communication module.

[0051] In this embodiment, the definition of the bottom plate as longitudinally arranged is only exemplary, and the bottom plate can be arranged according to actual needs as long as the bottom plate is perpendicular to the transverse plate (i.e., the first rolling screw pair and the second rolling screw pair form a 90-degree angle).

[0052] In use, the embodiment includes the following steps:

[0053] S1: Place the device in the large-diameter ring to be measured.

[0054] It should be noted that, for the sake of convenience, the height of the column should be greater than the axial height of the ring to be measured;

[0055] S2: Detect whether the device is horizontal by the horizontal detector on the base, and if not, keep the base horizontal by adjusting the support bolts at the four corners of the base.

[0056] S3: Align the first distance measuring device with the lowest height to be measured of the ring.

[0057] Specifically, after the base is kept horizontal, the third motor is controlled to work by the remote controller, the third motor drives the first driven gear to move up and down along the rack, thereby driving the first distance measuring device on the rotary driving component to move up and down, so that the first distance measuring device is aligned with the lowest height to be measured of the ring.

[0058] S4: Adjust the base and the cross beam to make the device column be at the center axis position of the ring to be measured.

[0059] Specifically, the fourth motor is controlled by the remote controller, the second driving wheel is driven by the fourth motor, the second driving wheel drives the rotating gear to rotate, and the first distance measuring device rotates around the column body. The rotating angle can be determined by the angle detection device. For example, when the angle detection device detects that the rotating angle is 0 degrees, the two measuring devices are located at 0 degrees and 180 degrees, respectively, and the two first measuring devices are longitudinal detection, that is, parallel to the base. When the angle detection device detects that the rotating angle is 90 degrees, the two first distance measuring devices are located at 90 degrees and 270 degrees, respectively, and the two first distance measuring devices are transverse detection. When transverse detection is compared, whether the distance values measured by the two first distance measuring devices displayed on the remote controller are the same, if not, the first rolling screw pair is adjusted by the first motor to adjust the horizontal direction, so that the two first distance measuring devices detect the same distance value. The same principle and operation are used to compare the distance values in longitudinal detection.

[0060] S5: According to actual needs, the height of the first distance measuring device is adjusted.

[0061] Specifically, after the longitudinal and transverse adjustments are completed, the third motor is controlled to work by the remote controller, the third motor works, the crawling support moves upward along the column body, and the slewing driving part moves upward, the height measuring device detects the distance from the crawling support to the base, and sends the detected distance to the first processor. The first processor sends the detected distance to the remote controller for display through the communication module. Assuming that the displayed distance value is H1, the actual measured height value is H 实际 =H1+H0, wherein H0 is a fixed height correction value, and the height correction value is the height difference between the height of the height measuring device and the height of the first distance measuring device.

[0062] S6: The distance from the inner wall of the ring member is collected by the first distance detection device.

[0063] Specifically, according to the height value detected by the height measuring device displayed by the remote controller, the crawling support is controlled to stop, so that the distance from the inner wall of the ring member is collected by the first distance detection device. In order to facilitate the description, it is recorded as L1 and L2, and the detected angle is sent to the first processor by the wireless communication module. The first processor sends the detected angle to the remote controller for display. The distance is recorded. It should be noted that the actual diameter value D=L1+L2+L0, wherein L0 is a diameter correction value, that is, the straight line distance of the two first distance detection devices, which is a fixed value measured in advance.

[0064] Then, the fourth motor of the rotary driving component is controlled to work through the remote controller, the fourth motor of the rotary driving component works, so that the rotating gear rotates around the column body, thereby driving the two first distance measuring devices to rotate, and the rotating angle detection device is used to detect the rotating angle, and the detected angle is sent to the first processor, and the first processor sends the detected angle to the remote controller through the wireless communication module for display, when the rotating angle reaches the required angle, such as 30 degrees, 60 degrees, 90 degrees and the like, the rotation is stopped, and the distances measured by the two first distance measuring devices are recorded as L3 and L4, and the like. The diameter ovality of the ring at the height is calculated through multiple measurements.

[0065] It should be noted that other heights are also measured in sequence.

[0066] The preferred embodiments of the utility model are described above only, and are not used to limit the utility model, for the maintenance personnel in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
