Description

Technical Field

[0001] The present invention relates to the technical field of laser outer diameter detection, and in particular to a full-automatic laser outer diameter detection device and method. Background Art

[0002] When measuring the outer diameter of a steel pipe, the traditional measurement method is to use a vernier caliper to measure the steel pipe. With the development of science and technology, the laser diameter gauge is a more efficient and convenient steel pipe diameter measurement device. It is mainly used for non-contact measurement and control of object size. In specific operations, laser scanning is used to measure the diameter of the steel pipe, and real-time online non-destructive testing of the maximum diameter, minimum diameter, average diameter, ovality and other information of the steel pipe is performed.

[0003] The Chinese patent application with publication number CN219319329U proposes a laser diameter gauge, including a housing, a groove for measuring the diameter of the object to be measured is arranged on the housing, the length direction of the groove is parallel to the moving direction of the object to be measured, and guide wheel groups are arranged on both sides of the housing, the guide wheel groups include two guide wheels, the axes of the two guide wheels are collinear and the axis direction is perpendicular to the length direction of the groove, the axes of the guide wheels are arranged horizontally, the two guide wheels are arranged on the housing in a sliding manner along the axis direction of the guide wheels, and a driving assembly for driving the two guide wheels to move closer to or away from each other is arranged on the housing. The advantage is that not only can the stability of the object to be measured when it is placed on the two guide wheels be improved by adjusting the distance between the two guide wheels, but also the stability of the object to be measured when it is placed on the two guide wheels can be further improved by adjusting the distance between the guide wheels and the housing.

[0004] The above diameter measuring device ensures the stability of the measured steel pipe when it is placed when performing the diameter measuring task. However, when the diameter measuring task is carried out, the degree of automation is low, and the measured steel pipe cannot be placed and measured or removed after measurement by itself. Correspondingly, manual removal is required, which is more labor-intensive.

[0054] A fully automatic laser outer diameter detection method, using a detection device as described above, comprises the following steps:

[0055] S1. Conveying and feeding

[0056] After the steel pipe to be tested is placed on the electric conveyor belt 2, it is placed into the receiving frame 51 by the electric conveyor belt 2. Due to the opening of the guide groove 53, the steel pipe after entering can be parked on the guide groove 53, and then the moving plate 55 is controlled to move to push the steel pipe toward the laser diameter measuring instrument body 3;

[0057] S2. Laser detection

[0058] In step S1, the steel pipe is pushed out of the material receiving frame 51 and falls onto the positioning wheel 571, where it is supported by the positioning wheel 571. Then, the laser emitting end on the laser diameter measuring instrument body 3 emits a laser and the receiving end receives the laser, thereby scanning and measuring the steel pipe.

[0059] S3. Steel pipe placement

[0060] When the outer diameter of the steel pipe is measured, the second electric push rod 587 pulls the first bracket 584 downward, causing the positioning wheel 571 on the inner side of the first bracket 584 to be lower than the positioning wheel 571 on the inner side of the second bracket 585, causing the steel pipe to tilt downward toward one end of the first bracket 584, and finally slide down under the influence of gravity to achieve the purpose of self-unloading.

[0061] In the actual operation process, firstly, the device is connected to the power supply, and the steel pipe to be measured for the outer diameter can be detected on the laser diameter gauge body 3. During the detection, the laser emitting end on the laser diameter gauge body 3 emits the laser, which is received by the receiving end. During this period, the laser can scan the steel pipe, thereby achieving the purpose of diameter measurement. This is an existing structure, so it will not be further described here. After the steel pipe is placed on the electric conveyor belt 2, it is transported to the direction of the material receiving frame 51 by the electric conveyor belt 2. The guide plate 52 can ensure that the steel pipe can accurately fall into the material receiving frame 51. When the steel pipe enters the material receiving frame 51, due to the guide groove 53 opened at the bottom of the material receiving frame 51, the steel pipe rolls after entering, and finally stays on the guide groove 53 and maintains a horizontal state with the guide groove 53, which is convenient for subsequent loading;

[0062] During feeding, the first motor 58 drives the threaded adjustment rod 57 to rotate after working, and the threaded adjustment rod 57 drives the moving plate 55 to move. After the moving plate 55 moves to fit one end of the steel pipe, the electromagnet 597 is de-energized at this time, and the electromagnet 597 does not adsorb the metal block 596. At this time, the spring 594 pulls the connecting plate 593 downward, and the connecting plate 593 drives the pressing block 592 to move downward to press one end of the steel pipe, so as to avoid the situation that most of the steel pipe moves out of the outside of the receiving frame 51 and tilts without accurate delivery, thereby improving the stability and safety of the feeding work;

[0063] The positioning wheel 571 in the device can provide support for the steel pipe. In order to accommodate steel pipes of different diameters and sizes to be stably placed, the spacing between two adjacent positioning wheels 571 can be adjusted. During the adjustment, the third electric push rod 589 pushes the strip plate 588 after working, and the strip plate 588 drives the inclined rod 573 to flip and swing. After the inclined rod 573 swings, it drives the control board 572 to move, and the control board 572 drives the positioning wheel 571 to move, thereby adjusting the spacing between adjacent positioning wheels 571, which can match the stable placement of steel pipes of different diameters, and in order to accommodate steel pipes of different diameters, The height of the material receiving frame 51 can be adjusted. When adjusting, the second motor 581 works and drives the bidirectional threaded rod 599 to rotate. The bidirectional threaded rod 599 drives the two threaded blocks 582 to move toward or away from each other. After the threaded block 582 moves, it drives the push-pull rod 583 to flip and swing. After the push-pull rod 583 swings, the lifting plate 591 is pushed and pulled up and down. It can be seen from the above connection relationship that the material receiving frame 51 can be adjusted in height at this time, so that steel pipes of various sizes can be accurately delivered, and the delivery is not unstable due to the diameter limit, which is too high or too low.

[0064] When the steel pipe stays at a position where it can be placed stably on the positioning wheel 571, in order for the steel pipe to quickly detach from the material receiving frame 51, first, the electromagnet 597 is re-energized to adsorb the metal block 596. It can be seen from the above steps that at this time, the pressing block 592 leaves the steel pipe, and then the first electric push rod 598 pulls the base 59 to move the material receiving frame 51 away from the laser diameter measuring instrument body 3, so as to ensure that the steel pipe and the material receiving frame 51 are fully and quickly separated. When the detection work is completed, the second electric push rod 587 pulls the first bracket 584 downward, causing the positioning wheel 571 inside the first bracket 584 to be lower than the positioning wheel 571 inside the second bracket 585. The steel pipe tilts downward toward one end of the first bracket 584, and finally slides down under the influence of gravity to achieve the purpose of self-unloading, thereby realizing the function of self-loading and unloading, avoiding the situation that manual operation is more labor-intensive.

[0065] Finally, in order to prevent the accumulation of dust from interfering with the receiving or transmitting end position on the laser diameter gauge body 3, the linkage plate 62 can be pushed and pulled up and down by the fourth electric push rod 68. The linkage plate 62 drives the mounting plate 65 to move, and the mounting plate 65 drives the cleaning layer 64 to move and wipe the laser receiving and transmitting ends on the laser diameter gauge body 3. After pressing the block 66 into the linkage plate 62, the rectangular plate 63 can be removed from the linkage plate 62, which is beneficial for the user to clean the cleaning layer 64 itself, effectively ensuring its dust removal performance and ensuring the accuracy of the detection work.

[0066] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
