Description

Technical Field

[0001] The invention relates to the technical field of steel pipe processing, and in particular to a steel pipe processing detection device and a detection method thereof. Background Art

[0002] After the galvanizing process is completed, the outer circumference of the steel pipe needs to be tested to ensure product quality and meet technical requirements. The outer circumference test can ensure that the diameter or roundness of the steel pipe is within the allowable range. If the outer diameter of the steel pipe exceeds the specified tolerance range, it may affect its connectivity and sealing in the pipeline system, and even cause safety hazards. This process requires the use of a detection device to detect the outer circumference of the galvanized steel pipe. Its main structure includes a measuring sensor, a support and positioning device, and a data processing system. The measuring sensor usually uses laser, optical scanning or mechanical methods to accurately measure the outer diameter or roundness of the steel pipe. The support and positioning device ensures that the steel pipe is stably fixed during the measurement process to ensure measurement accuracy. The data processing system receives and analyzes the data obtained by the sensor, displays and records the measurement results in real time, and supports further data analysis and quality control;

[0003] For example, a steel pipe galvanizing detection device and detection method disclosed in application publication number CN117387484A include a bottom plate, the surface of the bottom plate is fixedly connected to a support rod, the surface of the support rod is rotatably connected to a support roller, the surface of the bottom plate is fixedly connected to a support plate, the end of the support plate away from the bottom plate is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a conveying roller, the surface of the bottom plate is fixedly connected to a fixed plate, and the surface of the fixed plate is fixedly connected to a second motor, which can detect the flatness of the galvanized steel pipe body to avoid the situation where the zinc layer on the surface of some steel pipes is not enough after the steel pipe surface is galvanized. However, the above technical solution mainly relies on two obliquely symmetrical support rollers to transport the steel pipe horizontally and linearly during use. At this time, another independent second motor is required to drive the gear ring and several detection devices to rotate on the outer circumference of the steel pipe. During its operation, the horizontal movement function of the steel pipe and the revolution function of the detection device require at least two motors to complete. At this time, the operating status and control of each motor must be strictly synchronized to ensure that the device is consistent with the horizontal movement path of each steel pipe and the rotation path of the detection device during operation. Otherwise, the deviation and instability of the steel pipe measurement results may be caused by different detection paths on the outer circumference of the pipeline. Summary of the invention

The double-roller tube rotation structure and the dual-axis moving module share a rotation drive module and a tensioning pulley transmission module when working, so that the rotation movement of the galvanized steel pipe and the translation movement of the digital micrometer are always kept synchronized, so that each galvanized steel pipe workpiece being inspected undergoes the same rotation movement trajectory and the translation trajectory of the digital micrometer, ensuring that each galvanized steel pipe workpiece undergoes the same peripheral surface detection process, so as to solve the problems raised in the above-mentioned background technology.

The Z-axis screw lifting structure 803 used here adopts a screw linear module commonly used on the market;

[0034] The X-axis screw rod transverse movement structure 801 is interconnected with one end of one of the steel rollers 201 through the pulley transmission structure 12. The X-axis screw rod transverse movement structure 801 includes a screw rod rotatably installed inside the horizontal frame 7, and a nut pair installed at the threaded part of one end of the screw rod surface. The top of the nut pair is fixedly connected to the top wall of the right-angle slide 802, and the bottom end of the nut pair is slidably connected to the bottom wall of the horizontal frame 7. The screw rod is interconnected with one end of one of the steel rollers 201 through the pulley transmission structure 12.

At this time, the X-axis screw rod transverse movement structure 801 drives the horizontal movement of the digital display micrometer 11 and the rotation movement of the steel roller 201 and the steel pipe to always remain synchronized, thereby ensuring that each steel pipe obtains the same detection path.

[0035] A right angle platform 3, the right angle platform 3 is fixed on one side of the top of the double inverted T-shaped frame 1, and a rotation drive module 4 is installed on the inner wall of one side of the right angle platform 3, and a tensioning belt pulley transmission module 5 for driving the roller-type hosting self-rotating structure 2 to work is installed at the output end of the rotation drive module 4. Through the rotation drive module 4 and the tensioning belt pulley transmission module 5, the roller-type hosting self-rotating structure 2 realizes efficient and stable operation, the rotation drive module 4 provides rotational power and control, and the tensioning belt pulley transmission module 5 ensures the transmission stability of the motion;

[0036] The pulley transmission structure 12 is arranged on one side of the double inverted T-shaped frame 1 and is used to connect the roller-type hosting self-rotating structure 2 and the dual-axis moving module 8. A PLC control panel 301 is installed on the inner wall of one side of the right-angle table 3. The output end of the PLC control panel 301 is electrically connected to the rotation drive module 4 and the input end of the dual-axis moving module 8. The output end of the digital micrometer 11 and the CCD camera 10 is electrically connected to the input end of the PLC control panel 301. The rotation drive module 4 adopts a stepper motor, and the PLC control panel 301 controls the stepper motor to work according to the set direction, speed, angle, and response time.

[0037] The tensioning pulley transmission module 5 includes a driving wheel 505 installed at the output end of the rotating driving module 4, a driven wheel 504 fixed to one end of one of the steel rollers 201, and a first bearing seat 501 and a second bearing seat 502 installed on the back side of the double inverted T-shaped frame 1. The first bearing seat 501 and the second bearing seat 502 are both rotatably installed with a tensioning wheel 503. The outer peripheral surfaces of the driving wheel 505, the driven wheel 504 and the two tensioning wheels 503 are wrapped with tracks 506 in a V-shaped track. The tensioning wheels 503 on the first bearing seat 501 and the second bearing seat 502 have the purpose of tensioning and supporting the tracks 506, so as to ensure the transmission stability of the movement;

[0038] When the rotary drive module 4 and the tensioning pulley transmission module 5 drive the roller-type hosting self-rotating structure 2 to work, the rotary power of the rotary drive module 4 is transmitted to the driven wheel 504 through the driving wheel 505 and the crawler track 506, thereby driving a steel roller 201 in the roller-type hosting self-rotating structure 2 to rotate through the driven wheel 504;

[0039] The double inverted T-shaped frame 1 is composed of two inverted T-shaped side frames 101 with the same structure and a plurality of crossbeams 102 welded between the two inverted T-shaped side frames 101. The roller-type hosting self-rotating structure 2 includes two steel rollers 201 symmetrically mounted on the front and rear sides of the double inverted T-shaped frame 1. A gap is provided between the two steel rollers 201. When one of the steel rollers 201 rotates, the two steel rollers 201 support the galvanized steel pipe together. The rotating steel roller 201 causes the galvanized steel pipe to rotate under the action of friction, thereby changing the contact point between the galvanized steel pipe and the probe of the digital micrometer 11, thereby changing the outer circumference detection point of the galvanized steel pipe. The two symmetrically structured steel rollers 201 can be used to support galvanized steel pipes of different diameters to ensure their stable self-rotation, thereby ensuring that the digital micrometer 11 can accurately detect the galvanizing thickness and uniformity of the steel pipe during the self-rotation of the steel pipe.

[0040] The staff can also install a toothed disc at the same end of the two steel rollers 201. At this time, the two steel rollers 201 rotate synchronously, so that the galvanized steel pipe is no longer driven to rotate. Then, the galvanized steel pipe is in a non-rotating state and is detected by the digital micrometer 11, that is, the detection path of the digital micrometer 11 on the galvanized steel pipe is a straight line;

[0041] A steel pipe processing detection method of this embodiment, such as the steel pipe processing detection device mentioned above, comprises the following steps:

[0042] S101: The galvanized steel pipe to be subjected to outer circumference detection is placed on the roller-type tube-mounted self-rotating structure 2, and the roller-type tube-mounted self-rotating structure 2 is used to actively support the galvanized steel pipe workpiece;

[0043] S102: using the dual-axis moving module 8 to preliminarily control the probe height of the digital micrometer 11, that is, the dual-axis moving module 8 drives the Z-axis height of the bending plate 9, the CCD camera 10, and the digital micrometer 11 until the probe of the digital micrometer 11 touches the outer peripheral surface of the galvanized steel pipe workpiece;

[0044] S103: The rotation drive module 4 is turned on through the PLC control panel 301 to work, and a part of the rotation power of the rotation drive module 4 is transmitted to the roller-type tube self-rotating structure 2 through the tensioning pulley transmission module 5. At this time, the roller-type tube self-rotating structure 2 enables the galvanized steel pipe workpiece to rotate 360 ​​degrees evenly;

[0045] S104: The roller-type tube self-rotating structure 2 and the double-axis moving module 8 are connected by the pulley transmission structure 12, and the X-axis moving structure in the double-axis moving module 8 is driven by the pulley transmission structure 12, that is, the double-axis moving module 8 drives the bending plate 9, the CCD camera 10, and the digital display micrometer 11 to perform horizontal movement of the X axis, so that the probe of the digital display micrometer 11 moves along the extension direction of the galvanized steel pipe;

[0046] S105: Use the digital micrometer 11 to detect the outer circumference of the galvanized steel pipe in a continuously rotating state. The CCD camera 10 is used to capture the numerical value changes on the screen of the digital micrometer 11 and the image of the outer circumference of the steel pipe in real time, and feed it back to the PLC control panel 301 for the staff to retrieve and use.

[0047] Embodiment 2, based on embodiment 1, Figure 6-8 It is shown that a roller side support mechanism 13 for supporting the galvanized steel pipe workpiece at its side position is provided on one side of the back of the double inverted T-shaped frame 1. The roller side support mechanism 13 includes two hollow diagonal support plates 1301 fixed to the back of the double inverted T-shaped frame 1, a square bearing seat 1302 slidably installed inside the hollow diagonal support plate 1301, a cylinder 1303 installed on the top of the hollow diagonal support plate 1301, and a side support roller 1304 rotatably installed between the two square bearing seats 1302. The cylinder 1303 is movable The bottom end of the plug rod is fixedly connected to the top end of the square bearing seat 1302. In order to keep the galvanized steel pipe in a relatively stable state during rotation, the staff controls the cylinder 1303 through the PLC control panel 301 to work, and the cylinder 1303 drives the square bearing seat 1302 and the side support roller 1304 to move down or up until the side support roller 1304 contacts the outer wall of the steel pipe to be tested, so as to support the steel pipe at the side by using the side support roller 1304 to ensure the stable rotation of the steel pipe.

[0048] When the embodiment of the present application is in use, the staff places the galvanized steel pipe to be inspected for outer circumference on the roller-type hosting self-rotating structure 2, and uses the roller-type hosting self-rotating structure 2 to actively support the galvanized steel pipe workpiece. Then the staff turns on the dual-axis moving module 8 through the PLC control panel 301 to work, and uses the dual-axis moving module 8 to preliminarily control the probe height of the digital micrometer 11, that is, the dual-axis moving module 8 drives the bending plate 9, the CCD camera 10, and the Z-axis height of the digital micrometer 11 until the probe of the digital micrometer 11 touches the outer circumference of the galvanized steel pipe workpiece, thereby completing the digital micrometer 11. After the position adjustment between the galvanized steel pipe workpiece and the digital display micrometer 11 and the galvanized steel pipe workpiece are debugged, the staff turns on the rotation drive module 4 through the PLC control panel 301 to work, and then a part of the rotation power of the rotation drive module 4 is transmitted to the roller-type hosting self-rotating structure 2 through the tensioning pulley transmission module 5. At this time, the roller-type hosting self-rotating structure 2 enables the galvanized steel pipe workpiece to rotate 360 ​​degrees evenly, so that the digital display micrometer 11 can detect the galvanizing condition of its outer peripheral surface. In this process, since the roller-type hosting self-rotating structure 2 and the dual-axis moving module 8 maintain power connection through the pulley transmission structure 12, The X-axis motion structure in the dual-axis motion module 8 is driven by the pulley transmission structure 12, that is, the dual-axis motion module 8 drives the bending plate 9, the CCD camera 10, and the digital micrometer 11 to perform horizontal motion of the X-axis, so that the probe of the digital micrometer 11 moves along the extension direction of the galvanized steel pipe, so as to use the digital micrometer 11 to detect the outer circumference of the galvanized steel pipe in a rotating state. In this process, the CCD camera 10 is used to capture the numerical value change on the screen of the digital micrometer 11 and the image of the outer circumference of the steel pipe in real time, and the PLC control panel 301 receives and processes the image from the CCD camera 10. The detection data of the surface and the digital micrometer 11 are used to control and adjust the operation of the rotation drive module 4 and the dual-axis movement module 8 through preset programs and logics, ensuring the synchronization and coordination of various components during the working process, so as to provide users with traceable detection data, thereby providing digital measurement results of the outer circumference of the steel pipe. During the measurement process, for multiple galvanized steel pipes of the same specification and model, each steel pipe undergoes the same rotation and translation detection trajectory, which ensures the consistency and comparability of the measurement data, eliminates the measurement errors caused by inconsistent motion, and thus improves the accuracy and reliability of the measurement of the outer circumference of the galvanized steel pipe.
