[0023] The following is combined with Figure 1-Figure 2 The present application is further described with reference to the following specific examples:

[0024] First of all, it should be noted that in the description of this application, if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and other directional words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this application; in addition, if the terms "first", "second", "third" and other numerical quantifiers appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limited connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0025] like Figures 1 to 2 As shown, a pipe end size detection system includes: a manipulator 2, a servo motor 3 is fixed at the end of the manipulator 2, a detection device 4 is fixed on the output shaft of the servo motor 3, the detection device 4 includes a rotating frame, the rotating frame includes a first rod 41 and a second rod 42 and a third rod 43 perpendicular to the first rod 41, the second rod 42 and the third rod 43 are arranged parallel and spaced apart, the first rod 41 is fixedly connected to the output shaft of the servo motor 3, and the first rod 41 is perpendicular to the output shaft of the servo motor 3; a first displacement laser sensor 44 is fixed on the second rod 42, and two second displacement laser sensors 45 are fixed on the third rod 43.

[0026] In the present application, the manipulator 2 moves the servo motor 3 and the detection device 4 thereon to the appropriate position of the steel pipe end to be inspected, starts the servo motor 3, and the servo motor 3 drives the rotating frame to rotate. When the rotating frame rotates, a first displacement laser sensor 44 fixed on the second rod 42 and two second displacement laser sensors 45 fixed on the third rod 43 will perform circular motion around the steel pipe end with the rotating frame. In this process, the first displacement laser sensor 44 and the second displacement laser sensor 45 will emit a laser beam and receive reflected light. By measuring the round-trip time or phase change of the laser, the distance from the sensor to each point on the surface of the steel pipe is accurately measured. Since the sensor continuously collects data during the circular motion, combined with the angle information of the rotation, the radial dimension data of the steel pipe end at different positions can be calculated, and then the inner and outer diameters, ovality and other dimensional parameters of the steel pipe end are calculated based on these data. The ovality is obtained by comparing and analyzing the data of multiple measurement points at different circumferential positions, and the wall thickness and other related dimensional information are calculated by the measurement data at a specific position.

[0027] Two second displacement laser sensors 45 are fixed on the third rod 43 , and this design can ensure parallelism during the rotation process.

[0028] The coordination of manipulator 2 and servo motor 3 enables precise positioning and automatic rotational testing of detection device 4, eliminating the need for extensive manual intervention and improving detection efficiency and consistency. The use of a laser displacement sensor, with its high measurement accuracy, enables precise acquisition of various dimensional data on steel pipe ends, effectively reducing measurement errors and ensuring accurate product quality control.

[0029] Specifically, a laser profiler 46 is fixed on the first rod 41 , and the laser profiler 46 is located between the second rod 42 and the third rod 43 .

[0030] The laser profiler 46 ensures that the distance of the measuring tool entering the steel pipe is maintained at an optimal distance of about 4680 mm from the laser profiler.

[0031] Specifically, the third rod 43 is longer than the second rod 42 , and the second rod 42 and the third rod 43 are arranged in parallel. The third rod 43 is located at an end of the second rod 42 away from the servo motor 3 .

[0032] The two second laser displacement sensors on the third rod 43 ensure that the detection tooling remains parallel to the length direction of the steel pipe. The first laser displacement sensor on the second rod 42 and the second laser displacement sensor on the third rod 43 ensure that the pipe wall remains vertical during the entire measurement process. The lasers emitted by the first laser displacement sensor and the second laser displacement sensor are vertically projected onto the pipe wall.

[0033] Specifically, the first displacement laser sensor 44 corresponds to the middle of the two second displacement laser sensors 45 .

[0034] Specifically, it also includes carrying devices 5 distributed on both sides of the robot arm 2. Each carrying device 5 includes two mounting seats 51. A carrying roller 52 is rotatably provided on the mounting seat 51.

[0035] Since the carrying devices 5 are distributed on both sides of the manipulator 2 and each carrying device 5 can hold two steel pipes, the two steel pipes can be tested in turn. When the steel pipe on the carrying device 5 on one side is being tested, the steel pipe on the carrying device 5 on the other side can be prepared for loading or unloading. After the test is completed, the manipulator 2 can quickly switch to the steel pipe on the carrying device 5 on the other side for testing, which greatly reduces the waiting time during the testing process and significantly improves the overall testing efficiency. It is especially suitable for the rapid testing scenario of batch steel pipes.

[0036] Furthermore, a driving motor connected to the carrying roller 52 is fixed on the mounting seat 51 , and the driving motor is used to drive the carrying roller 52 to rotate.

[0037] Specifically, it also includes a fixed bracket 6 , on which a plurality of photoelectric sensors 61 are fixed. The photoelectric sensors 61 are used to detect whether there is a tube to be detected on the carrying device 5 .

[0038] The photoelectric sensor 61 can quickly and accurately detect whether there is a tube to be inspected on the carrier device 5. By emitting and receiving light signals, once the light signal is blocked or reflected by the tube body and changes, the sensor can immediately sense it and transmit the signal to the control system, thereby accurately determining the presence or absence of the tube body, providing a reliable basis for the automated control of the subsequent inspection process.

[0039] Specifically, it also includes a base 7 , on which a calibration tool 71 is fixed.

[0040] Before inspecting the workpiece to be inspected, the calibration fixture 71 is checked and calibrated to check whether the moving path of the manipulator 2 is accurate.

[0041] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, ordinary technicians in this field should understand that technicians in the relevant technical field can still modify or replace the present application with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
