[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0022] Please refer to the attached Figure 1 To Attachment Fig.12 The invention describes a multifunctional fixture of an online monitoring platform for a welding pool.

[0023] On a welding production line, it is often necessary to use sensors to monitor the molten pool. In the prior art, multiple fixtures are set up for use, and each fixture fixes a camera module, so as to facilitate multi-angle and multi-directional monitoring of different targets. Although the overall monitoring effect of the fixture in the prior art is improved compared with the traditional monitoring components, there are still certain problems. For example, the above-mentioned fixture cannot adjust the monitoring angle in real time during use. Each time the welding molten pool is monitored, the monitoring angle needs to be adjusted in advance. Secondly, it is impossible to synchronously adjust the monitoring angles of multiple fixtures during monitoring.

[0024] The monitoring component includes a laser tracking sensor 2, a molten pool monitoring sensor 3, and a workpiece temperature detection sensor 4, and the laser tracking sensor 2, the molten pool monitoring sensor 3, and the workpiece temperature detection sensor 4 are arranged on the mounting seat 16 at equal intervals along the circumferential array direction.

[0025] Therefore, the multifunctional fixture of the welding molten pool online monitoring platform includes a protective cover 1, a mounting seat 16 is provided in the protective cover 1, a monitoring component is provided on the mounting seat 16, and the monitoring component can rotate relative to the mounting seat 16. An independent monitoring structure is provided in the protective cover 1, and the independent monitoring structure independently adjusts the monitoring angle of any sensor in the monitoring component. A synchronous monitoring structure is provided in the protective cover 1, and the synchronous monitoring structure synchronously adjusts the monitoring angles of all sensors in the monitoring component. Furthermore, when welding to different areas, the angles to be monitored are often different. Therefore, the independent monitoring structure is used to separately adjust the monitoring angles of the laser tracking sensor 2, the molten pool monitoring sensor 3 and the workpiece temperature detection sensor 4, and the synchronous monitoring structure is convenient for simultaneously driving the laser tracking sensor 2, the molten pool monitoring sensor 3 and the workpiece temperature detection sensor 4 to adjust the monitoring angles.

[0026] Furthermore, a universal rotating seat 506 is connected to the monitoring component, and the monitoring component is rotatably connected to the mounting seat 16 via the universal rotating seat 506 .

[0027] The independent monitoring structure includes an angle adjustment component 10 arranged in the protective cover 1, the angle adjustment component 10 adjusts the monitoring angle of any sensor in the monitoring component, and a limit component 11 is provided on the angle adjustment component 10 to fix the adjusted position after the monitoring angle adjustment of any sensor in the monitoring component is completed. Specifically, the angle adjustment component 10 includes a plurality of electromagnets 1001 connected to the protective cover 1, and the monitoring components are connected to strong magnets 1002. When the electromagnets 1001 are energized, the monitoring components can adjust the angle through the strong magnets 1002. Each sensor in the monitoring component is connected to a connecting plate 1005, and an electric telescopic rod 1003 is connected to the connecting plate 1005. The telescopic end of the electric telescopic rod 1003 is connected to a magnetic shielding cover 1004, and the magnetic shielding cover 1004 is sleeved on the strong magnet 1002. When the magnetic shielding cover 1004 is covered on the strong magnet 1002, the strong magnet 1002 and the electromagnet 1001 cancel the magnetic The strong magnet 1002 is magnetically connected to the electromagnet 1001 when the magnetic shielding cover 1004 is removed from the strong magnet 1002. When one of the electromagnets 1001 is energized, the electromagnet 1001 is magnetic. Since each sensor in the monitoring component is equipped with a strong magnet 1002, the strong magnet 1002 can be attracted by the magnetic force of the electromagnet 1001 and can drive the monitoring component to adjust its angle. Since a plurality of electromagnets 1001 are provided and are evenly spaced in a circular array, the monitoring component can be adjusted at multiple angles within a range of 360 degrees, and has better adaptability. After the adjustment is completed, the electric telescopic rod 1003 and the magnetic shielding cover 1004 can be moved downward so that the magnetic shielding cover 1004 covers the strong magnet 1002, thereby avoiding the situation in which the remaining strong magnets 1002 are attracted by the electromagnet 1001 and the angle changes when the monitoring angle of the next monitoring component is adjusted.

[0028] It should be noted that, in order to ensure the magnetic shielding effect of the magnetic shielding cover 1004 , the material of the magnetic shielding cover 1004 can be selected from conductive rubber, metal mesh or organic conductive material.

[0029] Preferably, the electric telescopic rod 1003 is an electric telescopic rod 1003 , and in other embodiments of the present invention, it can also be other models.

[0030] In order to ensure that the monitoring component will not move after the angle adjustment is completed, and to ensure the stability of its monitoring, the limiting component 11 includes a plurality of connecting rods 1101 connected to the magnetic shielding cover 1004, and the end of the connecting rod 1101 away from the magnetic shielding cover 1004 is connected to a universal ball, and the universal ball is rotatably connected to a connecting seat 1102, and the end of the connecting seat 1102 away from the universal ball is connected to a first airbag 1103, and the first airbag 1103 is connected in the mounting seat 16 to limit the universal rotating seat 506, and the first airbag 1103 is connected to a connecting tube, and the other end of the connecting tube is connected to a second airbag 1104, and the second airbag 1104 is connected to the magnetic shielding cover 1004. The airbag 1104 is connected to the mounting seat 16, and a slide plate 12 is slidably connected to the second airbag 1104. A plurality of compression springs 13 are connected to the slide plate 12. The end of the compression spring 13 away from the slide plate 12 is connected to the inner wall of the second airbag 1104. Specifically, when the monitoring component is in normal use, the first airbag 1103 is filled with gas. At this time, the first airbag 1103 can limit the universal rotating seat 506, thereby preventing the universal rotating seat 506 from rotating, that is, the monitoring component cannot rotate at this time. When the monitoring angle of a single monitoring component needs to be adjusted, the electric telescopic rod 1003 pushes the magnetic shielding cover 1004 to move upward. , so that the magnetic shielding cover 1004 no longer generates magnetic shielding for the strong magnet 1002, and then the magnetic shielding cover 1004 drives the connecting rod 1101 to move vertically upward, so that the connecting seat 1102 squeezes the first airbag 1103. At this time, the gas in the first airbag 1103 is compressed into the second airbag 1104, and because the gas in the first airbag 1103 is emptied, the first airbag 1103 can no longer limit the rotation position of the universal rotating seat 506. At this time, the angle of the monitoring component is convenient to adjust. Similarly, it can be known that after the adjustment is completed, the angle of the monitoring component is adjusted, and the magnetic shielding cover 1004 moves downward to the strong magnet 1002. Magnetic shielding, at this time, the gas in the second airbag 1104 enters the first airbag 1103 again, so that the first airbag 1103 limits the universal rotating seat 506 again, that is, the monitoring component cannot rotate at this time, and in order to facilitate the gas in the second airbag 1104 to rebound into the first airbag 1103, a slide plate 12 is slidably connected inside the second airbag 1104, and a plurality of compression springs 13 are connected to the other side of the slide plate 12, and the other end of the compression spring 13 is connected to the inner wall of the second airbag 1104. The arranged compression spring 13 can increase the thrust of the slide plate 12, so as to facilitate the gas in the second airbag 1104 to re-enter the first airbag 1103.

[0031] When it is necessary to adjust the monitoring angles of the laser tracking sensor 2, the molten pool monitoring sensor 3 and the workpiece temperature detection sensor 4 at the same time, the synchronous monitoring structure includes a lateral adjustment component 14 arranged on the protective cover 1, and the lateral adjustment component 14 adjusts the monitoring angles of all sensors in the monitoring component laterally. The lateral adjustment component 14 is provided with a vertical adjustment component 15, and the vertical adjustment component 15 adjusts the monitoring angles of all sensors in the monitoring component vertically.

[0032] Specifically, the lateral adjustment assembly 14 includes a fixing plate 1401 disposed on the protective cover 1, and two mutually symmetrical fixing seats 1402 are connected to the fixing plate 1401, and a worm 1403 is rotatably connected between the two fixing seats 1402, and the fixing seat 1402 at the first direction end is connected to a first servo motor 1404 that drives the worm 1403 to rotate, and a worm wheel 1405 is meshingly connected to the worm 1403, and a rotating shaft 1406 is connected to the worm wheel 1405, and a connecting frame 1407 is connected to the rotating shaft 1406, and the connecting frame 1407 is connected to the mounting plate 14 08, one end of the mounting plate 1408 away from the connecting frame 1407 is connected to the protective cover 1, and starting the first servo motor 1404 can drive the worm 1403 to rotate, and then the worm 1403 can drive the worm wheel 1405 to rotate, and then the rotating shaft 1406 connected to the worm wheel 1405 can drive the connecting frame 1407 and the mounting plate 1408 to adjust the lateral angle. Since the mounting plate 1408 is connected to the protective cover 1, the laser tracking sensor 2, the molten pool monitoring sensor 3 and the workpiece temperature detection sensor 4 can synchronously adjust the lateral angle.

[0033] Specifically, the vertical adjustment component 15 includes a second servo motor 1501 disposed on a fixed seat 1402 at the second direction end, a short-circuited shaft is connected to the driving end of the second servo motor 1501, the short-circuited shaft is rotatably connected to the fixed seat 1402, a transmission rod 1502 is connected to the short-circuited shaft, the other end of the transmission rod 1502 is connected to a fixed frame 1503, a rotating shaft 1406 is rotatably connected to the fixed frame 1503, and the second servo motor 1501 can be started to drive the transmission rod 1502 to rotate, and the fixed frame 1503 can be driven during the rotation of the transmission rod 1502. Rotate, at this time the fixed frame 1503 can drive the rotating shaft 1406 to rotate, and then the rotating shaft 1406 can drive the mounting plate 1408 to adjust the angle again, through the coordinated use of the lateral adjustment component 14 and the vertical adjustment component 15, the lateral adjustment component 14 and the vertical adjustment component 15 need to be adjusted in sequence to enable the laser tracking sensor 2, the molten pool monitoring sensor 3 and the workpiece temperature detection sensor 4 to adjust the angle in two axial directions, so that the laser tracking sensor 2, the molten pool monitoring sensor 3 and the workpiece temperature detection sensor 4 can monitor more comprehensively.

[0034] In order to facilitate the installation of laser tracking sensors 2, molten pool monitoring sensors 3 and workpiece temperature detection sensors 4 of different shapes, a clamping assembly 5 for fixing the sensors in the monitoring assembly is provided in the mounting seat 16, and the clamping assembly 5 includes a mounting frame 501, and the mounting frame 501 is connected to a universal rotating seat 506, and a transmission ring 502 is rotatably connected in the mounting frame 501, and a plurality of guide grooves 503 are arranged in a circular array with the center of the mounting frame 501 as the midline at equal intervals, and a guide rod 504 is slidably connected in the guide groove 503. The universal rotating seat 506 provided first facilitates the mounting frame 501 and the monitoring assembly fixed in the mounting frame 501 to be adjusted at multiple angles, and rotating the transmission ring 502 can drive the guide groove 503 to rotate, and the guide rod 504 sliding in the guide groove 503 during the rotation process can drive the transmission block 505 to move toward the center of the mounting frame 501 to clamp and fix the monitoring assembly, and in order to further improve the stability of the fixation of the monitoring assembly, the guide rod 5 04 is connected with a transmission block 505, one end of which is detachably connected with a positioning member 8, and a positioning bolt 9 is threadedly connected to the transmission block 505, one end of which extends into the positioning member 8, and one side of the positioning member 8 is connected with an anti-slip sleeve, and the replacement of the positioning member 8 is convenient for the contact area with the monitoring component, and the fixing effect of the monitoring component is further improved. Please refer to the figure, after the fixing is completed, a force block 6 is connected to one side of the transmission ring 502, so that one end of the force block 6 extends to the installation frame 50 1, and a connecting groove for the force block 6 to slide is opened on one side of the installation frame 501, and an elastic limiting clamp 7 is connected to one side of the installation frame 501. Rotating the force block 6 can drive the transmission ring 502 to rotate. When the force block 6 is clamped into the elastic limiting clamp 7, the position of the transmission ring 502 can be fixed. Since the elastic limiting clamp 7 is set to an elastic material, such as elastic rubber, and an anti-slip pattern is set in the elastic limiting clamp 7, the force block 6 can be fixed and easy to open.

[0035] Working principle: When the monitoring component needs to be clamped and fixed: The rotating transmission ring 502 can drive the guide groove 503 to rotate. During the rotation of the guide groove 503, the guide rod 504 sliding inside the guide groove 503 can drive the transmission block 505 to move toward the center of the installation frame 501 to clamp and fix the monitoring component. When the monitoring angle of the monitoring component needs to be adjusted: When a certain electromagnet 1001 is energized, the electromagnet 1001 is magnetic at this time. Since the monitoring components are all equipped with strong magnets 1002, the strong magnets 1002 can be attracted by the magnetic force of the electromagnets 1001 and can drive the monitoring components to adjust their angles. Since there are multiple electromagnets 1001 and they are evenly spaced in a circular array, the monitoring components can be adjusted at multiple angles within a range of 360 degrees, and the adaptability is better. After the adjustment is completed and the angle of the monitoring component is adjusted, the magnetic shielding cover 1004 moves downward to magnetically shield the strong magnet 1002. At this time, the gas in the second airbag 1104 enters the first airbag 1103 again, so that the first airbag 1103 again limits the universal rotating seat 506, that is, the monitoring component cannot rotate at this time; When you need to adjust the angles of multiple monitoring components at the same time: Starting the first servo motor 1404 can drive the worm 1403 to rotate, and then the worm 1403 can drive the worm wheel 1405 to rotate, and then the shaft 1406 connected to the worm wheel 1405 can drive the connecting frame 1407 and the mounting plate 1408 to adjust the horizontal angle. Since the mounting plate 1408 is connected to the protective cover 1, the laser tracking sensor 2, the molten pool monitoring sensor 3 and the workpiece temperature detection sensor 4 can synchronously adjust the horizontal angle. Starting the second servo motor 1501 can drive the transmission rod 1502 to rotate, and the transmission During the rotation of rod 1502, fixed frame 1503 can be driven to rotate, and fixed frame 1503 can drive rotating shaft 1406 to rotate, and then rotating shaft 1406 can drive mounting plate 1408 to adjust the angle again. By using lateral adjustment component 14 and vertical adjustment component 15 in coordination, laser tracking sensor 2, molten pool monitoring sensor 3 and workpiece temperature detection sensor 4 can be adjusted in angle in two axes, so that laser tracking sensor 2, molten pool monitoring sensor 3 and workpiece temperature detection sensor 4 can monitor more comprehensively.
