[0002] Prefabricated steel parts are steel structure components that are prefabricated in factories or workshops. Prefabricated steel parts are made into structural components with specific shapes, sizes and connection methods by cutting, welding, drilling and other processing technologies according to design requirements. These components are produced in a factory environment and then transported to the construction site for assembly to form a complete steel structure building or structure. Steel columns, steel beams, steel trusses, etc. are all prefabricated steel parts. Welding is the key step to connect the cut steel parts into prefabricated parts. According to the structural characteristics and requirements of the prefabricated parts, choose the appropriate welding method, such as manual arc welding, gas shielded welding, etc. H-shaped steel column is a kind of prefabricated steel structure.

The bottom of the driving motor 310 is fixedly connected to the top of the base 1. When in use, the web in the H-shaped steel column is placed on the unloading mechanism 3 and its two sides are aligned parallel to the clamping mechanism 5. Then, the web is fixed by adsorption through the unloading mechanism 3, and then the flange plate to be welded is inserted into the clamping mechanism 5 for clamping and clamping, and the clamping mechanism 5 is adjusted by the large electric slide rail 2 to move to the position where it fits and docks with both sides of the web. At this time, the angle between the welder 7 and the web and the flange plate is adjusted by the arc-shaped mechanical arm 8. The web and flange plates are butted together and the arc-shaped mechanical arm 8 is driven by the small electric slide rail 6 to drive the welder 7 to move horizontally to weld the angle between the web and the flange plate. After the web and flange plates are welded, the clamping mechanism 5 is used to release the clamping of the flange plate, and then the hydraulic push rod 4 drives the unloading mechanism 3 to move down to the height where the unloading can be carried out. After the unloading mechanism 3 releases the adsorption and fixation of the H-shaped steel column, the welded H-shaped steel column is slid and unloaded by rolling contact. The web to be welded is placed on the electric roller 303 on the storage table 301, and the two sides of the web are adjusted to a position parallel to the clamping mechanism 5. The bottom of the annular cylinder 305 is squeezed and contacted with the annular rubber pad 306 on the top of the annular cylinder 305, and then the storage platform 301 is pushed upward by the hydraulic push rod 4. When the storage platform 301 moves upward, the inner sliding circular plate 307 in the annular cylinder 305 slides downward relative to it. When the inner sliding circular plate 307 moves downward in the annular cylinder 305, it tightly absorbs and fixes the web on the top of the annular rubber pad 306. By arranging an annular rubber pad 306 that can be squeezed and compressed on the top of the annular cylinder 305 to make a close fit with the bottom surface of the web, when the H-shaped steel column is welded, the storage platform 301 is driven downward by the hydraulic push rod 4.

When the inner smooth circular plate 307 moves upward, it drives the cleaning component 308 on the top to move upward in the annular cylinder 305. When the inner smooth circular plate 307 moves upward in the annular cylinder 305, it gradually reduces the suction force on the bottom surface of the web until the cleaning component 308 moves up to the top surface with the inner smooth circular plate 307 and contacts with the bottom surface of the web, thereby releasing the adsorption and fixation on the web. The inner smooth circular plate 307 moves upward relative to the inner wall of the annular cylinder 305 to gradually release the adsorption and fixation on the bottom surface of the web. After the web loses the adsorption and fixation, the electric roller 303 is started to rotate. When the electric roller 303 rotates, it drives the H-shaped steel column on the top to slide and unload together.

[0013] For the second embodiment, please refer to Figure 1-Figure 8The present invention provides a welding device for steel structure prefabricated parts: a cleaning assembly 308 comprises a circular top block 3081, a corrugated ring piece 3082 is sleeved and rotatably connected to the outer surface of the circular top block 3081, a brush 3083 is fixedly connected to the outer surface of the corrugated ring piece 3082, a side connecting rod 3084 is fixedly connected to the outer surface of the circular top block 3081, a conical thorn block 3085 is fixedly connected to the bottom of the side connecting rod 3084, and the bottom of the circular top block 3081 is connected to the inner sliding circular plate 307. The top is rotatably connected by a rotating bolt, the side of the corrugated ring piece 3082 close to the circular top block 3081 is fixedly connected to the top of the inner sliding circular plate 307, a plurality of side connecting rods 3084 are provided, and the plurality of side connecting rods 3084 are distributed on the outer surface of the circular top block 3081 above the corrugated ring piece 3082, a plurality of conical thorn blocks 3085 are provided, and the plurality of conical thorn blocks 3085 are distributed at the bottom of the side connecting rods 3084 and the position where the corrugated concave seam of the corrugated ring piece 3082 is aligned; The clamping mechanism 5 includes a rectangular frame plate 501, a servo motor 502 is fixedly connected to the top of the rectangular frame plate 501, a threaded long rod 503 is fixedly connected to the driving shaft of the servo motor 502, a built-in slide plate 504 is sleeved and threadedly connected to the outer surface of the threaded long rod 503, a square clamp plate 505 is fixedly connected to one side of the built-in slide plate 504, a concave card groove 506 is provided on one side of the square clamp plate 505, both sides of the inner wall of the concave card groove 506 are provided with built-in circular grooves 507, a built-in sliding rod 508 is slidably connected to the inner wall of the built-in circular groove 507, one end of the built-in sliding rod 508 is fixedly connected to a rounded clamp plate 509, a push spring 510 is fixedly connected to the side of the rounded clamp plate 509 close to the built-in sliding rod 508, and the bottom of the rectangular frame plate 501 is fixedly connected to the outer surface of the threaded long rod 503. The top of the large electric slide rail 2 is slidably connected, and the side of the square clamp plate 505 away from the built-in slide plate 504 is fixedly connected to the side of the small electric slide rail 6. The end of the threaded long rod 503 away from the servo motor 502 is rotatably connected to the inner wall of the rectangular frame plate 501 through a rotating bolt. There are multiple built-in sliding rods 508, and the multiple built-in sliding rods 508 are distributed on the inner side of the push spring 510. The end of the push spring 510 away from the rounded clamp plate 509 is fixedly connected to the inner wall of the concave groove 506. When in use, when the inner sliding circular plate 307 drives the top circular top block 3081 and the corrugated ring piece 3082 to move upward relatively in the annular cylinder 305, the circular top block 3081 contacts the bottom surface of the web first. By setting the circular top block 3081 on the top of the inner sliding circular plate 307 81 first contacts the bottom surface of the web and separates the bottom surface of the web from the corrugated ring piece 3082 by one end. After the H-shaped steel column slides and unloads from the storage platform 301 by rolling contact, the cleaning assembly 308 on the inner sliding circular plate 307 is still at the same horizontal position as the annular rubber pad 306. At this time, the driving motor 310 is started to drive the linkage rod 309 to rotate. The linkage rod 309 rotates to drive the inner sliding circular plate 307 on the top to rotate. When the inner sliding circular plate 307 rotates, it drives the corrugated ring piece 3082 on the top to rotate at a high speed. At this time, the circular top block 3081 that is rotatably connected to the inner sliding circular plate 307 does not rotate. When the corrugated ring piece 3082 rotates at a high speed, it is gradually stretched outward toward the direction close to the annular rubber pad 306 under the action of centrifugal force. When the corrugated ring piece 3082 extends, the brush 3083 on the outer surface is driven to gradually approach the annular rubber pad 306 until it contacts the annular rubber pad 306. As the corrugated ring piece 3082 rotates, the brush 3083 rubs and cleans the surface of the annular rubber pad 306 when it contacts the annular rubber pad 306. After the brush 3083 has cleaned the surface of the annular rubber pad 306, the driving motor 310 reduces the rotation speed of the corrugated ring piece 3082. When the rotation speed of the corrugated ring piece 3082 decreases, the elastic restoring force drives the brush 3083 on the outer surface to gradually shrink inward to a position away from the annular rubber pad 306. When the corrugated ring piece 3082 that has returned to a corrugated shape rotates, the conical thorn block 3085 at the bottom of the side connecting rod 3084 is always located in the corrugated groove of the corrugated ring piece 3082.By setting a conical thorn block 3085 at the bottom of the side connecting rod 3084 to clean the debris from the corrugated groove of the rotating corrugated ring piece 3082, by setting a conical thorn block 3085 that is always aligned with the corrugated groove at the bottom of the side connecting rod 3084 and the distance between the bottom of the conical thorn block 3085 and the bottom of the inner wall of the corrugated groove is short, after the web plate is adsorbed and fixed on the electric roller 303, the flange plate is placed between the two rounded clamping plates 509 in the concave groove 506, and then After that, the servo motor 502 is started to drive the threaded long rod 503 to rotate. When the threaded long rod 503 rotates, it drives the two built-in slide plates 504 in the rectangular frame plate 501 to move toward the flange plate. When the built-in slide plate 504 moves, it drives the square clamp plate 505 on one side to move. The movement of the square clamp plate 505 drives the built-in sliding rod 508, the rounded clamp plate 509 and the pushing spring 510 in the concave slot 506 to move together. When the rounded clamp plate 509 contacts the flange plate, the flange plate is gradually inserted between the two rounded clamp plates 509 along the rounded surface. The rounded surface at the top of the rounded clamp plate 509 is arranged to facilitate the flange plate to be inserted between the two rounded clamp plates 509 through the rounded sliding surface. When the flange plate is inserted between the two rounded clamp plates 509, the pushing spring 510 pushes the rounded clamp plate 509 through the extension force to clamp and fix the flange plate so that it is always aligned parallel to the two sides of the web plate. The rounded clamp plate 509 elastically connected to the pushing spring 510 is arranged in the concave slot 506 To adjust and clamp flange plates of different thicknesses, when the flange plate is inserted between the two rounded clamping plates 509, the rounded clamping plates 509 are pushed to both sides. When the rounded clamping plates 509 move to both sides, the push spring 510 is compressed and the built-in slide bar 508 on one side is driven to slide in the built-in circular groove 507. The built-in circular groove 507 is provided in the concave card groove 506 to facilitate the movement of the built-in slide bar 508 and the rounded clamping plate 509 is slidably limited by the built-in slide bar 508.

[0014] When the present invention is operated and used, the web in the H-shaped steel column is placed on the unloading mechanism 3 and its two sides are aligned parallel to the clamping mechanism 5, and then the web is fixed by adsorption through the unloading mechanism 3, and then the flange plate to be welded is inserted into the clamping mechanism 5 for clamping and clamping, and the clamping mechanism 5 is adjusted by the large electric slide rail 2 to move to the position where it fits and docks with the two sides of the web. At this time, the arc-shaped mechanical arm 8 is used to adjust the welding device 7 to dock with the angle between the web and the flange plate, and the arc-shaped mechanical arm 8 is driven by the small electric slide rail 6 to drive the welding device 7 to move horizontally to weld the angle between the web and the flange plate. After the welding of the web and the flange plate is completed, the clamping and clamping of the flange plate is released by the clamping mechanism 5, and then the unloading is driven by the hydraulic push rod 4. The material mechanism 3 moves down to a height where the material can be unloaded. After the adsorption and fixation of the H-shaped steel column is released by the unloading mechanism 3, the welded H-shaped steel column is slidably unloaded by rolling contact. The web to be welded is placed on the electric roller 303 on the storage table 301, and the two sides of the web are adjusted to a position parallel to and aligned with the clamping mechanism 5. At the same time, the bottom of the web is squeezed and contacted with the annular rubber pad 306 on the top of the annular cylinder 305, and then the storage table 301 is pushed upward by the hydraulic push rod 4. When the storage table 301 moves upward, the inner sliding circular plate 307 in the annular cylinder 305 slides downward relative to it. When the inner sliding circular plate 307 moves downward in the annular cylinder 305, it tightly adsorbs and fixes the web on the top of the annular rubber pad 306. An annular rubber pad 306 that can be squeezed and compressed is arranged on the top of the cylinder 305 to make a close fit with the bottom surface of the web. When the H-shaped steel column is welded, the storage platform 301 is driven downward by the hydraulic push rod 4. At this time, the inner smooth circular plate 307 moves upward relatively in the annular cylinder 305. When the inner smooth circular plate 307 moves upward, it drives the cleaning component 308 on the top to move upward in the annular cylinder 305. When the inner smooth circular plate 307 moves upward in the annular cylinder 305, the suction force on the bottom surface of the web is gradually reduced until the cleaning component 308 releases the adsorption and fixation on the web when it moves up to the top surface and contacts the bottom surface of the web as the inner smooth circular plate 307 moves upward. The adsorption and fixation on the bottom surface of the web is gradually released by the upward relative movement of the inner smooth circular plate 307 on the inner wall of the annular cylinder 305. After the web loses its adsorption and fixation, the electric roller 303 is started to rotate. When the electric roller 303 rotates, it drives the top H-shaped steel column to slide and unload together. When the inner sliding circular plate 307 drives the top circular top block 3081 and the corrugated ring piece 3082 to move upward relatively in the annular cylinder 305, the circular top block 3081 contacts the bottom surface of the web first. By setting the circular top block 3081 on the top of the inner sliding circular plate 307 to contact the bottom surface of the web first and separate the bottom surface of the web from the corrugated ring piece 3082 by one end, after the H-shaped steel column slides and unloads from the storage table 301 by rolling contact, the cleaning component 308 on the inner sliding circular plate 307 is still at the same horizontal position as the annular rubber pad 306. At this time, the driving motor 310 is started to drive the linkage rod 309 to rotate.The linkage rod 309 rotates to drive the inner smooth circular plate 307 on the top to rotate. When the inner smooth circular plate 307 rotates, it drives the corrugated ring piece 3082 on the top to rotate at a high speed. At this time, the circular top block 3081 that is rotatably connected to the inner smooth circular plate 307 does not rotate. When the corrugated ring piece 3082 rotates at a high speed, it is gradually stretched outwardly close to the annular rubber pad 306 under the action of centrifugal force. When the corrugated ring piece 3082 stretches, it drives the brush 3083 on the outer surface to gradually approach the annular rubber pad 306 until it contacts the annular rubber pad 306. As the corrugated ring piece 3082 rotates, the brush 3083 rubs and cleans the surface of the annular rubber pad 306 when it contacts the annular rubber pad 306. After the brush 3083 has cleaned the surface of the annular rubber pad 306, it is driven by the driving motor 310 to reduce The rotation speed of the small corrugated ring piece 3082 is reduced. When the rotation speed of the corrugated ring piece 3082 becomes smaller, the brush 3083 on the outer surface is driven by the elastic restoring force to gradually shrink toward the inner corrugation to a position away from the annular rubber pad 306. When the corrugated ring piece 3082 that has restored to a corrugated shape rotates, the conical thorn block 3085 at the bottom of the side connecting rod 3084 is always located in the corrugated groove of the corrugated ring piece 3082. The corrugated groove of the rotating corrugated ring piece 3082 is cleaned of debris by arranging the conical thorn block 3085 at the bottom of the side connecting rod 3084. The conical thorn block 3085 that is always aligned with the corrugated groove is arranged at the bottom of the side connecting rod 3084, and the distance between the bottom of the conical thorn block 3085 and the bottom of the inner wall of the corrugated groove is short, so that the web is adsorbed and fixed on the electric roller 30 3, the flange plate is placed between the two rounded clamping plates 509 in the concave slot 506, and then the servo motor 502 is started to drive the threaded long rod 503 to rotate. When the threaded long rod 503 rotates, it drives the two built-in slide plates 504 in the rectangular frame plate 501 to move toward the flange plate. When the built-in slide plate 504 moves, it drives the square clamping plate 505 on one side to move. The movement of the square clamping plate 505 drives the built-in sliding rod 508, the rounded clamping plate 509 and the push spring 510 in the concave slot 506 to move together. When the rounded clamping plate 509 contacts the flange plate, the flange plate is gradually inserted between the two rounded clamping plates 509 along the rounded surface. The rounded surface on the top of the rounded clamping plate 509 is arranged to facilitate the flange plate to be inserted between the two rounded clamping plates 509 through the rounded sliding surface. When the flange plate is inserted between the two rounded clamping plates 509, the push spring 510 pushes the rounded clamping plate 509 through the extension force to clamp and fix the flange plate so that it is always aligned parallel to the two sides of the web plate. The rounded clamping plate 509 elastically connected to the push spring 510 is arranged in the concave groove 506 to adjust and clamp flange plates of different thicknesses. When the flange plate is inserted between the two rounded clamping plates 509, the rounded clamping plate 509 is pushed to both sides. When the rounded clamping plate 509 moves to both sides, the push spring 510 is compressed and drives the built-in slide bar 508 on one side to slide in the built-in circular groove 507. The built-in circular groove 507 is provided in the concave groove 506 to facilitate the movement of the built-in slide bar 508 and the built-in slide bar 508 is used to slide and limit the rounded clamping plate 509.
