Description

Technical Field

[0001] This invention relates to the field of welding auxiliary equipment technology, and in particular to a compact pulsed composite magnetic field generator that can adapt to the welding torch posture. Background Technology

[0002] Pulsed composite magnetic field assisted welding technology is an important means to improve the microstructure and properties of welded joints and enhance welding quality. By applying a controllable pulsed composite magnetic field to the weld pool area, it is possible to effectively refine grains, reduce welding defects, and improve the mechanical properties of the weld.

[0003] Currently, most magnetic field generators for welding adopt a fixed structure, requiring manual adjustment in advance based on the welding position and welding torch posture. They cannot adaptively adjust the magnetic field direction and area of ​​action in real time according to changes in the welding torch posture during welding. This results in unstable effects of the magnetic field on the molten pool, making it difficult to meet the requirements of complex curved surface welding, all-position welding, and other similar conditions. Furthermore, existing magnetic field generators generally suffer from large size, cumbersome installation and disassembly, and poor compatibility with welding torches. This not only increases the overall complexity of the welding equipment but also affects the operational flexibility of the welding torch and reduces welding efficiency. Summary of the Invention

This invention solves the problems of existing magnetic field generators that cannot adaptively adjust with the welding torch posture, are cumbersome to install and disassemble, are large in size, and have poor adaptability. It achieves real-time synchronization between the magnetic field posture and the welding torch posture, ensures the stable effect of the magnetic field on the weld pool, and improves the ease of installation and operational flexibility of the equipment.

[0006] In a preferred embodiment, the quick-connect module includes a snap-fit ​​groove, a split-type clamp, an insulating and heat-insulating washer, a clamping ring, a rotating clamping rod, and a clamping bolt. The snap-fit ​​groove is located on the outer side of the top of the welding torch body; the split-type clamp is annularly snapped into the outer side of the snap-fit ​​groove; the insulating and heat-insulating washer is fitted onto the inner side of the split-type clamp; the clamping ring is fitted onto the outer side of the insulating and heat-insulating washer; the rotating clamping rod is rotatably connected to the outer side of one end of the clamping ring; and the clamping bolt is threadedly connected to the outer side of the end of the rotating clamping rod, the clamping bolt being used to lock and limit the opening end of the clamping ring.

The fixing frame is fixedly connected to the outer side of one end of the clamping ring; the connecting rod is fixedly connected to the lower surface of the fixing frame; the base plate is slidably connected to the outer side of the connecting rod; the first through hole is opened in the middle inner side of the fixing frame, and the welding gun head passes through the inner side of the first through hole; the second through hole is opened in the middle inner side of the base plate, and the welding gun head passes through the inner side of the second through hole.

[0008] In a preferred embodiment, the magnetic field generator includes a mounting base, a rotating connecting frame, a rotating connecting plate, a rotating fixing frame, an annular fixing ring, and a magnetic coil assembly.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1 - Figure 6 This embodiment provides a compact pulsed composite magnetic field generator that can adapt to the welding torch posture, including a welding torch body 1, and also includes a quick-connect module, a magnetic head connector, a magnetic field generator, an adaptive adjustment component, and a protective component.

[0017] The quick-connect module is located on the outer end of the welding gun head 101, enabling rapid installation and disassembly of the entire magnetic field generator and the welding gun head 101. For example... Figure 2 As shown, the quick-connect module includes a snap-fit ​​slot 2, a split clamp 201, an insulating and heat-insulating washer 202, a clamping ring 203, a rotating clamping rod 204, and a clamping bolt 205. The snap-fit ​​groove 2 is located on the outer side of the top of the welding gun head 101 and is an annular groove structure. The split clamp 201 consists of two semi-annular clamps, which are snapped onto the outer side of the snap-fit ​​groove 2 to achieve axial positioning. The insulating and heat-insulating gasket 202 is made of high-temperature resistant insulating material and is fitted inside the split clamp 201 to isolate the high temperature and electromagnetic interference of the welding gun head 101. The clamping ring 203 is fitted outside the insulating and heat-insulating gasket 202 and is an open annular structure. The rotating clamping rod 204 is rotatably connected to the outer side of one end of the clamping ring 203, and the clamping bolt 205 is threaded to the outer side of the end of the rotating clamping rod 204. By rotating the clamping bolt 205, the opening of the clamping ring 203 can be reduced, thereby tightly pressing the split clamp 201 and the insulating and heat-insulating gasket 202 into the snap-fit ​​groove 2 of the welding gun head 101 to achieve quick locking and fixing.

[0018] It should be noted that: in this embodiment, the insulating and heat-insulating gasket 202 is preferably made of ceramic fiber composite material with a thickness of 3mm, which can withstand high temperature; in practical applications, for low-temperature welding scenarios, mica sheets or aluminum silicate fiber paper with a thickness of 1.5mm can also be selected to reduce costs and improve installation flexibility.

[0019] Meanwhile, the magnetic head connector is located on one side of the quick-connect module and is used to connect the quick-connect module and the magnetic field generator. For example... Figure 3 As shown, the magnetic head connector includes a fixed frame 3, a connecting rod 301, a base plate 302, a first through hole 303, and a second through hole 304. The fixed frame 3 is fixedly connected to the outer side of one end of the clamping ring 203 and has a disc-shaped structure. Multiple connecting rods 301 are evenly fixedly connected to the lower surface of the fixed frame 3. The base plate 302 is slidably connected to the outer side of the connecting rods 301 and can slide up and down along the connecting rods 301. The first through hole 303 is opened in the middle inner side of the fixed frame 3, and the second through hole 304 is opened in the middle inner side of the base plate 302. The welding gun head 101 passes through the inner sides of the first through hole 303 and the second through hole 304 in sequence to ensure that the magnetic head connector and the welding gun head 101 are coaxially arranged.

[0020] A magnetic field generator is located on one side of the magnetic head connector and is used to generate a pulsed composite magnetic field on the outer side of the welding gun head 101. For example... Figure 4 As shown, the magnetic field generating component includes a mounting base 4, a rotating connecting frame 401, a rotating connecting plate 402, a rotating fixing frame 403, an annular fixing ring 404, and a magnetic coil assembly 405. The mounting base 4 is threaded to the inner side of the second through hole 304, and its vertical position on the base plate 302 can be adjusted by the thread. The rotating connecting frame 401 is fixedly connected to the lower surface of the mounting base 4 and has a U-shaped structure. The rotating connecting plate 402 is rotatably connected to the inner side of the end of the rotating connecting frame 401 and can rotate around the pin of the rotating connecting frame 401. The rotating fixing frame 403 is fixedly connected to the inner side of the top of the rotating connecting plate 402 and has an L-shaped structure. The annular fixing ring 404 is fixedly connected to the outer side of the end of the rotating fixing frame 403 and is coaxially arranged with the welding gun head 101. The magnetic coil assembly 405 is annularly mounted on the inner side of the annular fixing ring 404 and consists of multiple independently controlled electromagnetic coils, which can generate pulsed composite magnetic fields of different directions and intensities.

[0021] It should be noted that the magnetic coil group 405 consists of 6 independent enameled copper wire coils, each with 350 turns, a wire diameter of 0.8mm, an operating voltage of DC24V, and a rated current of 2A. The pulse frequency adjustment range is 5-150Hz, and the duty cycle adjustment range is 10%-90%. By changing the energizing sequence and current phase of different coils, various composite magnetic field forms such as longitudinal magnetic field, transverse magnetic field, or rotating magnetic field can be generated.

[0022] Furthermore, an adaptive adjustment component is disposed between the magnetic field generator and the magnetic head connector, used to adaptively adjust the spatial attitude of the magnetic field generator according to the welding attitude of the welding torch head 101. For example... Figure 3 As shown, the adaptive adjustment component includes a rotating block 5, a first telescopic rod 501, a rotating connector 502, and a second telescopic rod 503. The rotating block 5 is rotatably connected to the inner side of the end of the base plate 302 and can rotate around the pin of the base plate 302; the first telescopic rod 501 is installed on the inner side of the rotating block 5 and is an electric telescopic rod; the rotating connector 502 is fixedly connected to the outer side of one end of the rotating fixing frame 403, and the outer side of the end of the first telescopic rod 501 is rotatably connected to the inner side of the end of the rotating connector 502; the second telescopic rod 503 is installed on one side of the fixing frame 3 and is an electric telescopic rod, with its other outer side fixedly connected to one side of the base plate 302. The extension and retraction of the second telescopic rod 503 can drive the base plate 302 to slide up and down along the connecting rod 301, thereby adjusting the vertical position of the magnetic field generator; the extension and retraction of the first telescopic rod 501 can drive the rotating fixing frame 403 to rotate around the rotating connecting frame 401, thereby adjusting the tilt angle of the magnetic coil group 405 and realizing real-time synchronization between the magnetic field attitude and the attitude of the welding gun head 101.

[0023] It should be noted that: the first telescopic rod 501 and the second telescopic rod 503 are miniature electric push rods with a stroke of 50mm, a repeatability of ±0.1mm, and a response time of ≤0.2s; for automated welding scenarios requiring rapid response, they can be replaced with servo electric cylinders with the same stroke, improving the positioning accuracy to ±0.02mm. The attitude sensor 406 of this device can be a six-axis MEMS gyroscope MPU6050 with a sampling frequency of 100Hz and an angle measurement accuracy of ±0.5°; the sensor can be directly installed on the top of the fixed frame 3 and connected to the control system through a shielded cable to avoid welding electromagnetic interference; for welding robot applications, the attitude data of the robot controller can be directly read without the need for additional sensor installation.

[0024] Finally, protective components are installed on the outside of the magnetic field generator to protect internal components and dissipate heat. For example... Figure 4 As shown, the protective components include a cooling device 6, a cooling fan 601, and a splash guard 602. The cooling device 6 is installed on one side of the base plate 302 and is an air-cooled cooling device; the cooling fan 601 is fixedly connected to one side of the cooling device 6 and can blow air towards the magnetic coil assembly 405 for heat dissipation; there are two splash guards 602, which are rotatably connected to the outer ends of the base plate 302 respectively. They are made of high-temperature resistant transparent material and can prevent welding spatter from damaging the magnetic coil assembly 405 and other internal components, while not affecting the operator's observation of the welding process.

[0025] Working principle: When using this device, a quick installation operation is first performed: the two semi-rings of the split clamp 201 are respectively snapped into the pre-set annular snap-fit ​​grooves 2 of the welding gun head 101. The depth and width of the snap-fit ​​grooves 2 are precisely matched with the split clamp 201 to effectively prevent axial movement. Then, an insulating and heat-insulating washer 202 made of ceramic fiber composite material is fitted inside the split clamp 201. This washer can withstand temperatures above 800℃ and has excellent electromagnetic shielding performance, which can isolate the high temperature and electromagnetic interference generated by the welding gun head 101 during operation and protect the subsequent electrical components from damage. Next, the clamping ring 203 is fitted on the outside of the insulating and heat-insulating washer 202. The clamping rod 204 is rotated to align with the other end of the clamping ring 203. Finally, the clamping bolt 205 is tightened. The contraction force of the clamping ring 203 tightly fixes the split clamp 201 and the insulating and heat-insulating washer 202 to the welding gun head 101. The entire installation process can be completed in only 30 seconds without any special tools.

[0026] During the welding process, when the welding torch 101 is performing welding operations, the attitude sensor 406 installed on the welding equipment collects data such as the spatial angle, position, and movement speed of the welding torch 101 in real time and transmits these signals to the control system. The algorithm built into the control system calculates the optimal position and angle required by the magnetic coil group 405 in real time based on the preset magnetic field-attitude correspondence, and sends control commands to the first telescopic rod 501 and the second telescopic rod 503. The extension and retraction of the second telescopic rod 503 causes the base plate 302 to slide up and down along the three evenly distributed connecting rods 301, thereby precisely adjusting the vertical distance between the magnetic coil group 405 and the weld pool, ensuring that the magnetic field strength is always within the optimal range. The extension and retraction of the first telescopic rod 501 causes the rotating fixed frame 403 to rotate around the pin of the rotating connecting frame 401 through the rotating connector 502. At the same time, the rotating block 5 will automatically rotate with the angle change of the first telescopic rod 501, thereby realizing the continuous adjustment of the tilt angle of the magnetic coil group 405, so that the central axis of the magnetic coil group 405 is always parallel to the axis of the welding gun head 101, ensuring that the pulsed composite magnetic field can act evenly and stably on the weld pool area.

[0027] Meanwhile, under the control of the control system, multiple independent electromagnetic coils in the magnetic coil assembly 405 are energized with pulsed currents of different phases according to preset frequencies and duty cycles, generating a superimposed pulsed composite magnetic field. This magnetic field can electromagnetically stir the liquid metal in the weld pool, refine the grain structure, reduce welding defects such as porosity and cracks, and significantly improve the mechanical properties of the weld. The cooling device 6 continuously delivers cooling airflow to the magnetic coil assembly 405 through the cooling fan 601, carrying away the heat generated by the coils during operation and preventing damage to the coils due to overheating; the rotatable anti-spatter baffle 602 can adjust its angle according to the welding position, effectively blocking high-temperature spatter generated during welding and protecting the magnetic coil assembly 405 and other precision components from damage. After welding is completed, simply loosen the clamping bolts 205 to quickly remove the entire magnetic field generator from the welding gun head 101 for easy maintenance and replacement of the equipment.

[0028] This invention, by setting an adaptive adjustment component, utilizes the coordinated extension and retraction of the first telescopic rod 501 and the second telescopic rod 503, along with rotating components such as the rotating connecting frame 401 and the rotating connecting plate 402, to adjust the spatial angle and position of the magnetic field generator in real time according to the welding posture of the welding gun head 101. This ensures that the pulsed composite magnetic field generated by the magnetic coil group 405 always acts precisely on the weld pool area, guaranteeing the stability of the magnetic field-assisted welding effect. It is suitable for various welding conditions such as complex curved surfaces and all positions. The split clamp 201 is snapped into the snap-fit ​​groove 2 of the welding gun head 101, and a quick locking and fixing is achieved in conjunction with the rotating clamping rod 204 and the clamping bolt 205. The device is easy to install and disassemble, requiring no modification to the welding torch head 101. It is compatible with various models of welding torch heads 101. Simultaneously, the insulating and heat-insulating gasket 202 effectively isolates the high temperature and electromagnetic interference of the welding torch head 101, ensuring safe operation. The overall structure of this invention is compact. The magnetic coil assembly 405 adopts a ring-integrated design, combined with lightweight connectors and adjusters, significantly reducing the size and weight of the equipment without affecting the operational flexibility of the welding torch. Protective components are also included. The cooling device 6 and the cooling fan 601 dissipate heat from the magnetic coil assembly 405. The anti-splash baffle 602 prevents welding spatter from damaging internal components, extending the service life of the equipment.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
