Description

Technical Field

[0001] This utility model relates to the field of laser diameter measurement and correction technology, and more specifically to a laser diameter measurement and correction device for seamless steel pipes. Background Technology

[0002] The laser diameter measurement and correction device for seamless steel pipes is mainly used to accurately measure the outer diameter of steel pipes and correct production deviations in real time. It uses a laser sensor to perform a non-contact scan of the steel pipe, quickly acquiring diameter data. After comparing this data with the standard value, the deviation signal is transmitted to the control system, driving the correction mechanism to adjust rolling parameters. This ensures the outer diameter of the steel pipe meets accuracy requirements, reduces defective products, and is suitable for online inspection and dynamic adjustment in the rolling of seamless steel pipes.

[0003] In actual production, encountering products with multiple specifications necessitates frequent equipment changes to meet measurement requirements. This not only increases operational complexity and time costs but can also lead to low production efficiency, failing to cover the production needs of various specifications and limiting the flexibility of the production line. Enterprises struggle to quickly adjust production plans and product types according to market changes, reducing their responsiveness to evolving market demands and hindering their competitiveness. Furthermore, sensors cannot uniformly cover all angles of the steel pipe, limiting detection to fixed points. This makes it easy to miss areas such as localized depressions or uneven thickness caused by sagging due to weight, leading to the failure to detect critical defects in a timely manner and increasing product quality risks.

[0027] Reference Figure 3 , Figure 5 The lifting assembly 3 includes a chassis 301, a sleeve rod 302, a second internal gear 303, a lifting rod 304, a slot 305, and a pin 306. The chassis 301 is fixedly installed inside the upper part of the outer casing 101. One end of the sleeve rod 302 is movably connected to the chassis 301. The second internal gear 303 is fixedly installed on the outer wall of the sleeve rod 302 and meshes with a first internal gear 204. One end of the lifting rod 304 is movably connected to the other end of the sleeve rod 302. A fixing assembly 4 is fixedly installed on the other end of the lifting rod 304. Slots 305 are provided on the outer walls of both the lifting rod 304 and the sleeve rod 302. The pin 306 fixes the lifting rod 304 and the sleeve rod 302 through the slots 305. The device has a rotating component 2 and a lifting component 3. When the diameter measuring angle needs to be adjusted, the output end of the drive motor 203 drives the first internal gear 204 to rotate. The rotation of the first internal gear 204 drives the second internal gear 303, which meshes with it, to rotate. The rotation of the second internal gear 303 drives the upper component to rotate, thereby achieving the angle adjustment. When the diameter measuring height needs to be adjusted, the operator pulls out the pin 306 and pulls the lifting rod 304 up or down according to the height requirement. After reaching the required height, the pin 306 is reinserted into the slot 305 to fix the lifting rod 304 and the sleeve rod 302, which improves the adaptability of the device to a certain extent.

[0029] Reference Figure 4 , Figure 6 The telescopic diameter measuring assembly 5 includes a multi-stage electric actuator 501, a fixed disk 502, a transmission rod 503, a slider 504, a fixed plate 505, and a laser measuring device 506. The multi-stage electric actuator 501 is fixedly mounted on the front wall of the disk 403. The fixed disk 502 is fixedly mounted on the output end of the multi-stage electric actuator 501. One end of the transmission rod 503 is movably connected to the outer wall of the fixed disk 502. The slider 504 is movably connected to a groove 404 formed in the front wall of the disk 403.

The other end of 3 is movably connected, and the laser measuring device 506 is fixedly installed above the slider 504. It is equipped with a telescopic diameter measuring component 5, which is conducive to the output end of the multi-stage electric actuator 501 driving the fixed plate 502 to telescopically move. The telescopic movement of the fixed plate 502 drives the transmission rod 503 to horizontally expand and tighten. The expansion and tightening movement of the transmission rod 503 drives the fixed plate 505 and the slider 504 to translate along the slide groove 404. The translational movement of the slider 504 drives the laser measuring device 506 to translate, thus facilitating the device to measure the diameter of steel pipes facing different types of paper towels.

[0030] The working principle of this utility model:

[0031] First, the operator places the device horizontally on the ground. Then, they adjust the device according to the height and angle of the steel pipe. When the measuring angle needs adjustment, the output of the drive motor 203 rotates the first internal gear 204. This rotation drives the meshing second internal gear 303, which in turn rotates the upper components, thus adjusting the angle. When the measuring height needs adjustment, the operator removes the pin 306 and pulls the lifting rod 304 up or down according to the desired height. Once the required height is reached, the pin 306 is reinserted into the slot 305, securing the lifting rod 304 and the sleeve rod 302. This improves the device's adaptability to some extent.

[0032] Secondly, after adjustment, the output end of the multi-stage electric actuator 501 drives the fixed plate 502 to extend and retract. The extension and retraction of the fixed plate 502 drives the transmission rod 503 to extend and retract horizontally. The extension and retraction of the transmission rod 503 drives the fixed plate 505 and the slider 504 to move along the slide groove 404. The movement of the slider 504 drives the laser measuring device 506 to move horizontally, thus facilitating the device to measure the diameter of steel pipes of different diameters. After the diameter measurement is completed, the light emitted by the laser measuring device 506 is compared with the light received at the end of the steel pipe. If the number of emitted and received light beams is the same, the signal is defined as a standard signal. If there is a difference between the emitted and received light beams, the signal is defined as a non-standard signal and sent to the controller 105. After receiving the non-standard signal, the controller 105 controls the alarm 402 to sound an alarm, thereby reminding the staff to perform a calibration of the steel pipe until the diameter measurement shows a standard signal.
