Description

Technical Field

[0001] This invention relates to the field of axial flow fan housing processing technology, specifically to a laser welding post-processing grinding machine for industrial axial flow fan housings. Background Technology

[0002] Axial flow fans have a wide range of applications. They are fans that direct airflow in the same direction as the fan's axis, such as electric fans and air conditioner outdoor unit fans. They are called "axial flow" because the gas flows parallel to the fan's axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure. An axial flow fan is fixed in position and moves air. It mainly consists of a fan impeller and a casing. While its structure is simple, it requires very high precision. The casing is cylindrical, and ring-shaped flanges are often created at both ends using spinning or welding to enhance its strength and also to mount protective covers. In addition, the exterior of the casing has supports for mounting the casing, and the interior needs mounting brackets for the motor and fan blades.

[0003] In the production of axial flow fans, steel plates are rolled and welded, and then flanges and other structures are welded to the corresponding positions on the cylinder. During welding, fixtures are typically used to hold the flanges and cylinder in place, and the fixture position needs to be adjusted to assist welding. When welding axial flow fan casings of different sizes, fixtures usually need to be changed. Furthermore, the laser welding process for axial flow fan casings generates extremely fine fumes that affect the working environment. These fumes, with particle diameters mostly between 0.1 and 1 μm, are easily suspended in the air and, if not promptly removed, may adhere to the workpiece surface or the laser lens. Some components of the fumes (such as Cr...) 6+ Manganese compounds are toxic, and long-term inhalation can harm the respiratory tract. During the welding process, the high-energy laser causes the metal to vaporize rapidly. When the steam is ejected at high speed, it will generate a recoil force on the molten pool. If the molten pool is small and solidifies quickly, in order to adapt to the recoil force of the high-power laser energy, some liquid metal may be "blown away" from the molten pool, forming spatter and welding slag, which will adhere to the inner wall of the cylinder and are difficult to clean. If the surface is not treated before welding, it will affect the welding process and the quality, thereby affecting the production quality and efficiency. Based on this, a laser welding post-processing grinding machine for industrial axial flow fan housing is proposed. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the device is in use, the cylinder is placed on the outside of the hydraulic support frame two and sleeved on the outside of the hydraulic telescopic column three and the high-temperature resistant rubber roller. Then, the hydraulic active mechanism outputs hydraulic power to cause the pressure inside the sealed support cylinder to rise. The hydraulic power evenly lifts the hydraulic telescopic column three, causing the high-temperature resistant rubber roller to contact the inner wall of the cylinder. Then, the hydraulic support frame two is moved to the top of the rolling mechanism through the second ball screw mechanism, and the electric telescopic rod one is activated to push out the mounting plate, causing the alignment column and the electromagnet column to move, thereby causing the flange to move in the cylinder. On the outside of the cylinder, the hydraulic power output device then uses hydraulic power to simultaneously lower the hydraulic telescopic rods one and two to maintain a coaxial horizontal line, so that the outer wall of the cylinder contacts the outside of the high-temperature resistant rubber ring. The side cylinder limit seat is placed on the outside of the cylinder and flange. Then, the ball screw moving mechanism moves the welding adjustment frame to weld the connection between the cylinder and the flange. During the connection process, the airflow treatment mechanism is activated to extract the airflow from the inside of the cylinder and the inside of the mounting groove through the hollow tube, reducing the emission of smoke and dust. The overall operation is convenient and reduces the pollution of the operation. It can also adapt to the welding operation of cylinder shells of various sizes. 2. During operation, the height of the adjustable telescopic tube is pre-adjusted so that the steel brush filament bundle is in a state of compression contact with the inside of the cylinder. Then, the grinding motor is started and rotated, which drives the gear groove to rotate through the drive gear, thereby causing the hollow tube to rotate. This causes the adjustable telescopic tube and the hollow column to rotate. Finally, the steel brush filament bundle is used to grind the edge position that needs to be welded. 3. When the airflow treatment mechanism starts to adsorb the airflow, the powerful fan starts to draw out the airflow inside the axial flow mounting pipe and the guide pipe. The airflow is introduced through the corrugated hose and the air collection hood. The airflow in the corrugated hose is introduced through the support cylinder and the hollow pipe. The hollow pipe is connected through the adjustable telescopic pipe. The airflow enters the interior of the hollow column through the air inlet. During the grinding process, the debris and particles generated are drawn out through the hollow column, reducing the overflow. The airflow in the air collection hood is introduced through the mounting groove, reducing the dispersion of smoke and dust. The filter component adsorbs and filters the airflow, thereby reducing the overflow of particles and smoke and dust, and increasing the environmental protection effect of the equipment.

Detailed Implementation

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.

[0034] Please see Figures 1-12This invention provides a technical solution: a grinding machine for post-laser welding processing of industrial axial flow fan housings, comprising a worktable 1, a first ball screw mechanism 2 fixedly mounted on the top of the worktable 1, a hydraulic support frame 3 mounted on the transmission part of the first ball screw mechanism 2, a second ball screw mechanism 6 fixedly mounted on the top of the worktable 1, a hydraulic support frame 7 mounted on the transmission part of the second ball screw mechanism 6, a ball screw moving mechanism 4 mounted on the top of the worktable 1, and a hydraulic active mechanism fixedly mounted on the top of the worktable 1. 5. The output end of the hydraulic active mechanism 5 is connected to the output end of the hydraulic support frame 7. The top of the workbench 1 is provided with an installation groove 102. A rolling mechanism 8 is installed inside the installation groove 102. The top of the workbench 1 is provided with several adjustment holes 103. Two sets of side cylinder limit seats 104 are installed on the top of the adjustment holes 103 by bolts. The bottom of the workbench 1 is fixedly installed with a bottom support 101. An airflow treatment mechanism 9 is installed on the top of the bottom support 101. A hydraulic power output device 11 is fixedly installed on the top of the workbench 1.

[0035] The hydraulic support frame 3 includes two hydraulic telescopic rods 301. The moving part of the first ball screw mechanism 2 is fixedly installed on both hydraulic telescopic rods 301. The output end of the two hydraulic telescopic rods 301 is fixedly installed with a support cylinder 302. The outer side of the support cylinder 302 is interference-fitted with a support bearing frame 310. The outer wall of the support bearing frame 310 is welded with an electrically controlled telescopic rod 303. The output end of the electrically controlled telescopic rod 303 is fixedly installed with a mounting plate 305. The opposite side of the mounting plate 305 is fixedly installed with a support bearing 304. The support bearing 304 is movably sleeved on the outer side of the support cylinder 302. The mounting plate 305 has several alignment holes 309 inside. The inner side of the alignment holes 309 is movably inserted with a fixing bolt 307. The outer side of the fixing bolt 307 is threaded with an alignment post 306. One end of the alignment post 306 is fixedly installed with an electromagnet post 308. The inner side of the support cylinder 302 is sleeved with an inner grinding frame 13.

[0036] The hydraulic support frame 2 7 includes two hydraulic telescopic rods 2 701. Both hydraulic telescopic rods 2 701 are fixedly installed on the moving part of the second ball screw mechanism 6. The telescopic ends of the two hydraulic telescopic rods 2 701 are fixedly installed with sealing support cylinders 702. Several hydraulic telescopic columns 3 703 are fixedly installed on the outside of the sealing support cylinders 702. High-temperature resistant rubber rollers 704 are rolled on the outside of the hydraulic telescopic columns 3 703 through the bracket.

[0037] The rolling mechanism 8 includes a servo motor 801, the output end of which is connected to a rotating shaft 802. Several high-power electromagnets 804 are fixedly sleeved on the outside of the rotating shaft 802, and high-temperature resistant rubber rings 803 are fixedly sleeved on the outside of the high-power electromagnets 804.

[0038] The inner grinding frame 13 includes a hollow tube 1308, which is rolled and assembled inside the support cylinder 302 via several bearings. Several adjustable telescopic tubes 1301 are connected to the outside of the hollow tube 1308. A hollow column 1302 is connected to the top of the adjustable telescopic tube 1301. Several air inlets 1303 are opened inside the hollow column 1302. Several steel brush filament bundles 1304 are fixedly installed at the top of the hollow column 1302. Several gear grooves 1307 are opened on the outside of the hollow tube 1308. A drive gear 1306 meshes on the outside of the gear grooves 1307. A grinding motor 1305 is driven and connected to one end of the drive gear 1306.

[0039] The working principle of the above technical solution is as follows: In use, the cylinder is placed outside the hydraulic support frame 7 and sleeved on the outside of the hydraulic telescopic column 703 and the high-temperature resistant rubber roller 704. Then, the hydraulic active mechanism 5 outputs hydraulic power to pressurize the inside of the sealed support cylinder 702. The hydraulic power evenly lifts the hydraulic telescopic column 703, causing the high-temperature resistant rubber roller 704 to contact the inner wall of the cylinder. Then, the second ball screw mechanism 6 moves the hydraulic support frame 7 to the top of the rolling mechanism 8. Then, the first ball screw mechanism 2 causes the hydraulic support frame 3 to move into the inside of the cylinder. Due to the pre-adjustment of the adjustable telescopic tube 1301, the cylinder is fully functional. The height is adjusted so that the steel brush filament bundle 1304 is in a state of compressed contact with the inside of the cylinder. Then, the grinding motor 1305 is started and rotated, which drives the gear groove 1307 to rotate through the drive gear 1306, thereby causing the hollow tube 1308 to rotate. This causes the adjustable telescopic tube 1301 and the hollow column 1302 to rotate. Finally, the steel brush filament bundle 1304 grinds the edge position to be welded. Then, the annular flange to be welded is placed outside the electromagnet column 308, and the electromagnet column 308 is inserted into the circular hole on the annular flange surface. The electrically controlled telescopic rod 303 is activated to push out the mounting plate 305 and make the alignment column 302... 6. The electromagnet column 308 moves, thereby causing the flange to move to the outside of the cylinder. Then, the hydraulic power output device 11 uses hydraulic power to synchronously lower the hydraulic telescopic rod 701 and the hydraulic telescopic rod 301 to maintain a coaxial horizontal line, so that the outer wall of the cylinder contacts the outer side of the high-temperature resistant rubber ring 803. The side cylinder limit seat 104 is placed on the outside of the cylinder and the flange. Then, the ball screw moving mechanism 4 moves the welding adjustment frame 12 to weld the connection between the cylinder and the flange. As the welding is carried out, the servo motor 801 rotates, driving the rotating shaft 802 to rotate, thereby causing the high-strength electromagnet 804 and the high-temperature resistant rubber ring 803 to move. 03. A rotational effect is applied to the cylinder, which rotates under the rolling support of the high-temperature resistant rubber roller 704, assisting in the rotational welding. During the welding process, the airflow treatment mechanism 9 is activated to extract the airflow from the inside of the cylinder and the inside of the mounting groove 102 through the hollow tube 1308, reducing the dispersion of smoke and dust. The overall operation is convenient, and it can grind the welding process and remove the spatter that appears on the inner wall after welding. The debris and particles generated during the grinding process are discharged through the airflow guide of the hollow tube 1308 and the airflow treatment mechanism 9. The overall operation is convenient, reduces the pollution of the operation, and can adapt to the welding operation of cylinder shells of various sizes.

[0040] In another implementation scheme, such as Figures 1-5As shown, the ball screw moving mechanism 4 includes two support mounting brackets 401. A second ball screw mechanism 402 is mounted on the top of the two support mounting brackets 401. The moving part of the second ball screw mechanism 402 is connected to a ball moving seat 403. An electric telescopic rod 404 is fixedly mounted on the bottom of the ball moving seat 403. A welded adjusting bracket 12 is fixedly mounted on the output end of the electric telescopic rod 404 through a bolt seat.

[0041] The support mounting bracket 401 provides rotational support for the ball screw mechanism 402. When the ball screw mechanism 402 rotates, it moves the ball moving seat 403 through the threaded transmission force, thereby adjusting the position of the electric telescopic rod 404 and the welding adjustment bracket 12. This facilitates adjustment of the moving position according to the position of the welding cylinder and flange. Furthermore, the hydraulic support bracket 3, the hydraulic support bracket 7, the rolling mechanism 8, and the ball screw moving mechanism 4 are all on the same horizontal plane, thus ensuring that the cylinder is restricted to a single moving stroke, thereby enabling unidirectional moving welding, reducing misalignment in multidimensional movement, and facilitating welding.

[0042] In another implementation scheme, such as Figures 1-5 As shown, the welding adjustment frame 12 includes two double-arc frames 1201. The arc dimensions of the two double-arc frames 1201 are distributed with one large and one small. Both double-arc frames 1201 are fixedly installed at the output end of the electric telescopic rod 404. The interior of each double-arc frame 1201 is provided with an arc-shaped sliding groove 1202. A slider 1203 is slidably installed on the inner side of the arc-shaped sliding groove 1202. A welding head 1204 is threaded on the inner side of the slider 1203. The outer side of the welding head 1204 is provided with a thread. Clamping nuts 1205 are threaded on the outer sides of both ends of the welding head 1204. The clamping nuts 1205 are movably clamped on the outer side of the double-arc frame 1201.

[0043] The arc positions of the double-arc frame 1201 and the arc-shaped slide 1202 facilitate the circumferential adjustment movement trajectory of the welding head 1204. Furthermore, the arc dimensions of the two double-arc frames 1201 are different sizes, which expands the adjustment position of the welding head 1204 within a certain range. When position adjustment is required, simply loosen the clamping nut 1205 to release its clamping fixation on the double-arc frame 1201, causing the slider 1203 to slide within the arc-shaped slide 1202 to adjust the position of the welding head 1204. Then, tighten the clamping nut... Tightening the nut 1205 limits the slider 1203 and the welding head 1204. The purpose of this design is to expand the welding head 1204 relative to the cylinder welding position. When the double arc frame 1201 is installed at the bottom of the ball moving seat 403 through the bolt seat, it has a certain effect of changing the installation position around the circumference. It can adjust the relative installation welding position of the welding head 1204 relative to the cylinder. Since the cylinder rotates during the welding process, the welding head 1204 can maintain a stable welding position in subsequent welding after adjusting its position once.

[0044] In another implementation scheme, such as Figures 1-10 As shown, the support bearing 304 is loosely assembled on the outside of the support cylinder 302. The mounting plate 305 is evenly welded around the outer wall of the support bearing 304. The alignment holes 309 are evenly distributed linearly inside the mounting plate 305. The specifications and dimensions of the fixing bolt 307 are compatible with the specifications and dimensions of the alignment holes 309.

[0045] The purpose of loosely assembling the support bearing 304 on the support cylinder 302 is to allow the support bearing 304 and the mounting plate 305 to move on the outside of the support cylinder 302 when the electrically controlled telescopic rod 303 extends or retracts. The mounting plate 305 is welded to the outer wall of the bearing wall of the support bearing 304. Therefore, the mounting plate 305 can move laterally with the support bearing 304 and also rotate circumferentially following the welding process between the flange and the cylinder. One end of the electrically controlled telescopic rod 303 is mounted via the support bearing bracket 310. On the outer side of the support cylinder 302, because the support bearing bracket 310 and the outer side of the support cylinder 302 are interference-fitted, when the electrically controlled telescopic rod 303 extends or retracts, the fixing force of the support bearing bracket 310 is greater than that of the support bearing 304. This allows the support bearing 304 and the mounting plate 305 to be pushed and adjusted in position on the outer side of the support cylinder 302. The mounting part of the electrically controlled telescopic rod 303 is welded to the outer wall of the bearing wall of the support bearing bracket 310, thus allowing the electrically controlled telescopic rod 303 and the mounting plate 305 to rotate with it. The flange rotates through the circumferential position provided by the support bearing 304 and the support bearing bracket 310. During welding, the flange is fitted onto the outside of the electromagnet column 308 and onto the outside of the cylinder. At this time, the electric telescopic rod 303 pushes the alignment column 306, the electromagnet column 308, and the flange to the appropriate welding position. As welding progresses, the flange and the cylinder form a fixed point, while the rolling mechanism 8 continues to apply rotational force to the cylinder to adjust the welding position. At this time, the flange will inevitably rotate with the cylinder, thereby controlling the electromagnetic... The iron column 308, the alignment column 306, the mounting plate 305, and the electrically controlled telescopic rod 303 will rotate synchronously. Therefore, the support bearing 304 and the support bearing bracket 310 need to rotate with it to stabilize the position. The insertion limit of the fixing bolt 307 into the alignment hole 309 facilitates the installation of the alignment column 306 and allows for the replacement of new alignment columns 306 of different lengths. This can change the pushing position of the flange, assist the structure in operation, and increase the overall convenience.

[0046] In another implementation scheme, such as Figures 1-9As shown, the sealing support cylinder 702 has a hollow structure, and the hydraulic telescopic columns 703 are evenly distributed in a circular linear pattern on the outside of the sealing support cylinder 702. The interior of the hydraulic telescopic columns 703 is connected to the interior of the sealing support cylinder 702. The input end of the sealing support cylinder 702 is connected to the output end of the hydraulic active mechanism 5 through a pipe.

[0047] The hollow interior of the sealing support cylinder 702 facilitates the input of hydraulic oil. When the hydraulic active mechanism 5 inputs hydraulic oil into the interior of the sealing support cylinder 702 through the oil supply pipe, the hydraulic oil is delivered at equal pressure to the interior of the hydraulic telescopic column 703 through the chamber of the sealing support cylinder 702. The hydraulic telescopic column 703 synchronously lifts and expands, causing the high-temperature resistant rubber roller 704 to press against the inner wall of the cylinder, thereby causing the cylinder to be located outside the sealing support cylinder 702. This ensures that the sealing support cylinder 702 and the cylinder maintain a concentric rotational position. Furthermore, both the sealing support cylinder 702 and the support cylinder 302 maintain a synchronous position through the synchronous power output of the hydraulic power output device 11. This facilitates the coaxiality of the structure for auxiliary welding operations, increases the relative stability of the structure, and facilitates synchronization.

[0048] In another implementation scheme, such as Figures 1-12 As shown, the adjustment holes 103 are linearly and evenly distributed on the top of the worktable 1, and are also linearly and symmetrically distributed on both sides of the mounting groove 102. The servo motor 801 is embedded in the worktable 1 through the groove. The end of the rotating shaft 802 away from the servo motor 801 is rotatably fixed to the inner wall of the mounting groove 102 through a bearing seat. A second brush 809 is fixedly installed on one side of the powerful electromagnet 804, and one end of the second brush 809 is electrically slidingly in contact with a second slip ring 805. The second slip ring 805 is movably sleeved on the outside of the rotating shaft 802. A fixed support rod 806 is fixedly installed on one side of the second slip ring 805. The fixed support rod 806 is fixedly installed on the inner wall of the mounting groove 102. The first slip ring 808 is fixedly installed on the other side of the powerful electromagnet 804. A fixed brush 807 is electrically slidingly contacted on the outside of the first slip ring 808. The fixed brush 807 is fixedly installed on the inner wall of the mounting groove 102. The rotating shaft 802 is linearly and evenly distributed on the outside of the rotating shaft 802.

[0049] The position of the adjusting hole 103 facilitates the adjustment of the position of the side cylinder limiting seat 104. The side cylinder limiting seat 104 limits both ends of the cylinder and the flange, preventing cylinder displacement during welding and acting as an auxiliary limiting safety measure. The high-temperature resistant rubber roller 704 rotates in the same axial direction as the rolling mechanism 8 and the cylinder. The high-temperature resistant rubber roller 704 limits the lateral movement of the cylinder. Therefore, the limiting function of the side cylinder limiting seat 104 ensures that the cylinder is welded in a limited position. When the servo motor 801 rotates, it drives the rotating shaft 802 to rotate. The powerful electromagnet 804 generates electromagnetic force that applies an adsorption effect to the outer wall of the cylinder through the high-temperature resistant rubber ring 803, applying a rotational force to the cylinder. The power source for the powerful electromagnet 804 is an external power supply to the slip ring 805, which conducts electricity through the brushes of the brush 809. The slip ring 805 is fixed to the inner side of the mounting groove 102 by the fixed support rod 806. The second electromagnet 809 is fixed to the powerful electromagnet 804, thus enabling current conduction at one end. The current at the other end of the powerful electromagnet 804 is transmitted through a fixed slip ring 808 as the powerful electromagnet 804 rotates, and then through the outer side of the slip ring 808 to contact the brush of the fixed brush 807 to form a current loop. The fixed brush 807 is fixed inside the mounting groove 102, while the slip ring 808 is fixed outside the powerful electromagnet 804. Thus, a current loop can be achieved during rotation, thereby activating the electromagnetic effect of the powerful electromagnet 804. This application can also achieve this operation using a conventional permanent magnet, but the purpose of using a powerful electromagnet 804 is to address the issue that when welding machine housings of different sizes, the weight of the cylinders varies. If a magnetically fixed permanent magnet is used, the resistance may be greater for cylinders exceeding the weight, thus affecting the circumferential welding effect. Therefore, the electromagnetic effect of the powerful electromagnet 804 facilitates the perfect rotational conduction of the machine housing cylinder within a certain weight range, thereby assisting the operation.

[0050] In another implementation scheme, such as Figures 1-5 As shown, the hydraulic active mechanism 5 includes an electrically controlled telescopic column 501, which is fixedly installed on the top of the workbench 1. A dynamic sealing piston 504 is fixedly installed at the output end of the electrically controlled telescopic column 501. A sealing cylinder 502 is movably sleeved on the outside of the dynamic sealing piston 504. One end of the sealing cylinder 502 is connected to an oil supply line 503. The end of the oil supply line 503 away from the sealing cylinder 502 is connected to the inside of the sealing support cylinder 702. Hydraulic oil is provided inside the sealing cylinder 502, the oil supply line 503, the sealing support cylinder 702, and the hydraulic telescopic column 703.

[0051] When the electrically controlled telescopic column 501 applies hydraulic power to the sealing support cylinder 702, the electrically controlled telescopic column 501 starts and drives the power sealing piston 504 to move inside the sealing cylinder 502, thereby pushing the hydraulic oil through the oil supply line 503 to the inside of the sealing support cylinder 702. Then, the pressure of the sealing support cylinder 702 causes the hydraulic telescopic column 703 to rise to the inner wall of the housing cylinder. Thus, the extension and retraction of one electrically controlled telescopic column 501 realizes the synchronous extension and retraction of the hydraulic telescopic column 703, thereby assisting the operation, reducing the use of additional power, and increasing the effect of synchronous expansion.

[0052] In another implementation scheme, such as Figures 1-11 As shown, the adjustable telescopic tube 1301 is evenly distributed in a circular linear pattern on the outside of the hollow tube 1308. The air inlet 1303 and the steel brush filament bundle 1304 are evenly distributed in a linear, staggered pattern on the outside of the hollow column 1302. The grinding motor 1305 is fixedly installed on the outside of the support cylinder 302 via a bracket. The airflow handling mechanism 9 includes an air collection hood 902, which is fixedly installed on the bottom of the workbench 1. The position of the air collection hood 902 corresponds to the position of the mounting groove 102. A corrugated hose 901 is connected through one side of the air collection hood 902. The end of the corrugated hose 901 away from the air collection hood 902 is connected to the support cylinder 302. The internal components are interconnected. The bottom end of the air collection hood 902 is connected to a guide pipe 903. The guide pipe 903 is filled with a filter assembly 905. The guide pipe 903 is fixedly installed on the top of the base bracket 101. The other end of the guide pipe 903 is connected to an axial flow mounting pipe 904 through a flange and bolts. A retaining ring 907 is fixedly sleeved inside one end of the axial flow mounting pipe 904. One side of the retaining ring 907 contacts one side of the filter assembly 905. A powerful fan 906 is installed inside the axial flow mounting pipe 904 through a fan mounting bracket. The filter assembly 905 includes a polyester fiber mesh, HEPA-grade glass fiber filter cotton, and activated carbon fiber felt.

[0053] When the airflow handling mechanism 9 starts to adsorb airflow, the powerful fan 906 starts to draw out the airflow inside the axial flow mounting pipe 904 and the guide pipe 903. The airflow is introduced through the corrugated hose 901 and the air collection hood 902. The airflow in the corrugated hose 901 is introduced through the support cylinder 302 and the hollow pipe 1308. The hollow pipe 1308 is connected through the adjustable telescopic pipe 1301. The airflow enters the interior of the hollow column 1302 through the air inlet 1303, and then flows through the hollow column 1302, the adjustable telescopic pipe 1301, and the hollow pipe 1302. The hollow tube 1308, the support cylinder 302, and the corrugated hose 901 form an airflow circuit. The hollow tube 1308 is rolled inside the support cylinder 302 via multiple bearings, allowing debris and particles generated during grinding to be drawn out through the hollow tube 1302, reducing spillage. The airflow in the air collection hood 902 is introduced through the mounting groove 102, reducing the dispersion of smoke and dust. The airflow is then introduced into the guide pipe 903 through the corrugated hose 901 and the air collection hood 902, and finally filtered by the filter assembly 905. First, 10μm particles are filtered through a polyester fiber mesh, then 0.3μm particles are filtered through a HEPA-grade glass fiber filter, and finally, activated carbon fiber felt is used for adsorption, thereby reducing the leakage of particles and dust and increasing the environmental protection effect of the equipment. The baffle ring 907 is installed on one side of the guide pipe 903 through the axial flow mounting pipe 904 via a flange and bolts. The axial flow mounting pipe 904 itself is also an axial flow fan type. After installation, the axial flow mounting pipe 904 limits the filter assembly 905 to the guide pipe 903 through the baffle ring 907. The guide pipe 903 is fixedly welded to the outside of the base bracket 101, while the axial flow mounting pipe 904 is movable. In order to replace the filter assembly 905, the axial flow mounting pipe 904 is removed by unscrewing the bolts, thereby releasing the retaining ring 907 from limiting the filter assembly 905. This allows for the periodic replacement and maintenance of the filter assembly 905, increasing overall convenience. Furthermore, the flange structure at the output end of the axial flow mounting pipe 904 can be connected to an external exhaust pipe to discharge the extracted airflow, reducing the impact on the working environment.

[0054] In another implementation scheme, such as Figures 1-5 As shown, the output end of the hydraulic power output device 11 is connected to the hydraulic power output pipe 1101, and the output end of the hydraulic power output pipe 1101 is connected to the input ends of the hydraulic telescopic rod 301 and the hydraulic telescopic rod 701 respectively through pipelines.

[0055] The hydraulic power output device 11 serves as a hydraulic power output source. Through the symmetrical and equal-length transmission of the hydraulic power output pipe 1101, it causes the hydraulic telescopic rod 1 301 and the hydraulic telescopic rod 2 701 at the common output end to output synchronously. This ensures that the hydraulic telescopic rod 1 301 and the hydraulic telescopic rod 2 701 extend and retract synchronously, thereby ensuring that the sealing support cylinder 702 and the support cylinder 1 302 remain in a coaxial position, reducing the offset during operation, increasing the overall structural stability, and facilitating coaxial operation.

[0056] In another implementation scheme, such as Figures 1-5 As shown, a smart control console 10 is fixedly installed on the top of the workbench 1, and two vision sensors are fixedly installed at the bottom of the ball moving seat 403. The intelligent control console 10 is equipped with a welding control system.

[0057] The intelligent control console 10 serves as an intelligent control component. The welding execution unit comprises various hardware structures as per the application, including an intelligent sensing module employing two vision sensors: a 3D structured light camera with a resolution of 2048×1536+ and an infrared thermal imager, to acquire weld contours in real time. Internally, it features a 15.6-inch industrial-grade touchscreen with a resolution of 1920×1080+, and an embedded controller powered by an Intel Core i7 processor, supporting multi-threaded real-time computation. It integrates I / O interfaces and a PLC module to achieve equipment linkage control. The core functional modules of the welding control system include offline programming and path planning, supporting the import of CAD models to automatically generate welding trajectories, or recording and automatically optimizing manual operation paths through a teaching mode. Real-time adaptive control is provided for weld tracking based on visual detection. Quality monitoring and traceability include real-time display of welding curves, current, voltage, and temperature changes over time, automatic marking of abnormal points, and a visual operation panel for human-machine interaction, including "Automatic Mode," "Manual Mode," "Parameter Settings," and "Fault Diagnosis." The system includes modules that support one-click start of batch welding tasks or manual intervention to adjust parameters. The signal input terminal of the intelligent control console 10 transmits signals to the output terminals of two vision sensors via wires. The control output terminal of the intelligent control console 10 is connected to the control input terminals of the first ball screw mechanism 2, the first electrically controlled telescopic rod 303, the second ball screw mechanism 402, the third electrically controlled telescopic column 501, the second ball screw mechanism 6, the servo motor 801, the powerful electromagnet 804, the powerful fan 906, the welding head 1204, and the grinding motor 1305 via wires. The control of the powerful electromagnet 804 is relatively special. The current return is achieved through the slip ring 805 and the fixed brush 807 to realize the power supply control of the current loop, thereby facilitating the control start and adjustment of the current and voltage.
