Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding processing, and in particular to a steel structure prefabricated part welding device. Background Art

[0002] Prefabricated steel components are prefabricated in a factory or workshop. They are manufactured in accordance with design requirements by cutting, welding, drilling, and other processes to create structural components with specific shapes, sizes, and connection methods. These components are manufactured in a factory environment and then transported to the construction site for assembly to form a complete steel building or structure. Steel columns, beams, and trusses are all examples of prefabricated steel components. Welding is a key step in connecting cut steel components into prefabricated components. Depending on the structural characteristics and requirements of the prefabricated component, appropriate welding methods, such as manual arc welding and gas shielded welding, are selected. An example of a prefabricated steel component is an H-shaped steel column, which has a cross-section shaped like the letter "H," with the flanges and web connected by welding.

[0003] H-shaped steel columns are generally longer during production. At the same time, the flange plates of the welded H-shaped steel columns are usually located on both sides, resulting in a hollow area at the bottom. Due to its special shape, the H-shaped steel column is difficult to quickly move from the processing table after welding. Therefore, we proposed a welding device for steel structure prefabricated parts. Summary of the Invention

[0019] The present invention has the beneficial effects:

[0020] 1. The present invention drives the top H-shaped steel column to slide and unload together when the electric roller rotates, so as to prevent the H-shaped steel column from being difficult to quickly move off the processing table due to its special shape after welding. The brush rotating with the corrugated ring piece rubs and cleans the surface of the annular rubber pad when it contacts the annular rubber pad, so as to prevent excessive dust particles and debris from adhering to the surface of the annular rubber pad after long-term use, which affects the sealing performance of the contact between the annular rubber pad and the bottom surface of the web. The push spring pushes the rounded clamping plate through the extension force to clamp and fix the flange plate so that it is always aligned parallel to both sides of the web, so as to prevent the clamped flange plate from tilting significantly and being difficult to fit and dock with both sides of the web, requiring secondary adjustment.

[0021] 2. The present invention provides a discharging mechanism, and when the inner sliding circular plate moves downward in the annular cylinder, the web on the top of the annular rubber pad is tightly adsorbed and fixed, so as to prevent the flange plate and the web from being offset and tilted due to external forces and requiring secondary adjustment when the flange plate and the web are butt-welded. By providing an annular rubber pad that can be squeezed and compressed on the top of the annular cylinder, it can be in close contact with the bottom surface of the web, so as to prevent the bottom surface of the web from being uneven during production, which may cause the bottom of the web to be difficult to seal with the top of the annular cylinder at various locations when placed on the electric roller. The inner sliding circular plate is moved upward relative to the inner wall of the annular cylinder to gradually release the adsorption and fixation on the bottom surface of the web, so as to prevent the bottom surface of the web from being still tightly adsorbed by the annular cylinder after welding is completed, which may make it difficult for the electric roller to unload it by rolling. When the electric roller rotates, it drives the top H-shaped steel column to slide and unload together, so as to prevent the H-shaped steel column from being difficult to be quickly carried off the processing table after welding is completed due to its special shape.

[0022] 3. The present invention provides a cleaning component, and a circular top block is provided on the top of the inner sliding circular plate to first contact the bottom surface of the web and separate the bottom surface of the web from the corrugated ring piece by one end, so as to prevent the corrugated ring piece from being squeezed and contacted with the web for a long time when the built-in slide moves upward, affecting the elastic performance of the corrugated ring piece. The brush that rotates with the corrugated ring piece rubs and cleans the surface of the annular rubber pad when it contacts the annular rubber pad, so as to prevent excessive dust particles and debris from adhering to the surface of the annular rubber pad after long-term use, affecting the sealing performance of the contact between the annular rubber pad and the bottom surface of the web. A conical thorn block is provided at the bottom of the side connecting rod to clean the corrugated groove of the rotating corrugated ring piece, so as to prevent the gradual accumulation of excessive dust particles and debris cleaned in the corrugated groove of the corrugated ring piece, affecting the contraction performance of the corrugated ring piece. A conical thorn block is provided at the bottom of the side connecting rod, which is always aligned with the corrugated groove and the distance between the bottom of the conical thorn block and the bottom of the inner wall of the corrugated groove is short, so as to prevent the position of the corrugated groove from deviating from the conical thorn block every time the corrugated ring piece is stretched by centrifugal force and then elastically restored after losing the centrifugal force.

[0023] The invention provides a clamping mechanism by which the rounded corner surface of the rounded corner clamp is arranged to facilitate the insertion of the flange plate between the two rounded corner clamps through the rounded corner sliding surface, so that the flange plate is difficult to be inserted between the two clamps and clamped when there is no gap between the top surfaces of the two clamps in contact. The pushing spring pushes the rounded corner clamp to clamp and fix the flange plate by the extension force so that it is always aligned parallel to the two sides of the web plate, preventing the clamped flange plate from tilting significantly and being difficult to fit and dock with the two sides of the web plate, requiring secondary adjustment. The rounded corner clamp elastically connected to the pushing spring is provided in the concave clamping groove to adjust the clamping of flange plates of different thicknesses to prevent the difficulty in clamping and clamping flange plates of various sizes or slightly tilted flange plates when the fixed clamping groove is provided in the clamping plate. The built-in circular groove is provided in the concave clamping groove to facilitate the movement of the built-in sliding rod and the sliding limit of the rounded corner clamp by the built-in sliding rod, so that the rounded corner clamp elastically connected by the pushing spring is easily affected by external forces during welding and thus tilted and deviated, affecting the welding effect.

[0040] Among them, the unloading mechanism 3 includes:

[0041] A storage platform 301 is provided with a rectangular through hole 302;

[0042] The electric roller 303 is used to slide and unload the welded H-shaped steel column by rolling contact;

[0043] A rectangular through hole 302 is provided at the center of the top of the storage platform 301. The inner wall of the rectangular through hole 302 is rotatably connected to one end of the electric roller 303 via a rotating bolt.

[0044] The bottom of the storage platform 301 is fixedly connected to the driving shaft of the hydraulic push rod 4;

[0045] A large circular hole 304 is formed on the top of the storage platform 301. An annular cylinder 305 is fixedly connected to the inner wall of the large circular hole 304. An annular rubber pad 306 is fixedly connected to the top of the annular cylinder 305. An inner sliding circular plate 307 is slidably connected to the inner wall of the annular cylinder 305. A cleaning assembly 308 is fixedly connected to the top of the inner sliding circular plate 307. A linkage rod 309 is fixedly connected to the bottom of the inner sliding circular plate 307. The bottom of the linkage rod 309 is fixedly connected to the drive shaft of the drive motor 310.

[0046] There are multiple large circular holes 304, and the multiple large circular holes 304 are respectively distributed around the top of the storage table 301 near the edge. 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. Then, the flange plate to be welded is inserted into the clamping mechanism 5 to be clamped and the clamping mechanism 5 is adjusted by the large electric slide rail 2 to move it to a 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 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 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 is used to drive the unloading mechanism 3 to move down to the height where the material can be unloaded. 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. At the same time, the web 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 smooth circular plate 307 in the annular cylinder 305 slides downward relative to it. When the inner smooth 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, it is in close contact 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 is 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, 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 the bottom surface of the web, and the adsorption and fixation on the web are 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 H-shaped steel column on the top to slide and unload together.

[0047] For the second embodiment, please refer to Figures 1-8The present invention provides a welding device for prefabricated steel structures: a cleaning assembly 308 includes 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 fixedly connected to the inner sliding circular plate 307. The top is rotatably connected by a rotating bolt, and 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 at a position aligned with the corrugated concave groove of the corrugated ring piece 3082.

[0048] The clamping mechanism 5 includes a rectangular frame plate 501, the top of the rectangular frame plate 501 is fixedly connected to a servo motor 502, the driving shaft of the servo motor 502 is fixedly connected to a threaded long rod 503, the outer surface of the threaded long rod 503 is sleeved and threadedly connected to a built-in slide 504, one side of the built-in slide 504 is fixedly connected to a square clamp plate 505, one side of the square clamp plate 505 is provided with a concave card groove 506, the inner wall of the concave card groove 506 is provided with a built-in circular groove 507 on both sides, the inner wall of the built-in circular groove 507 is slidably connected to a built-in slide rod 508, one end of the built-in slide rod 508 is fixedly connected to a rounded clamp plate 509, the rounded clamp plate 509 is fixedly connected to a push spring 510 on the side close to the built-in slide rod 508, and the bottom of the rectangular frame plate 501 is fixedly connected to the servo motor 502. The top of the large electric slide rail 2 is slidably connected, and the side of the square clamping 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 slide rods 508, and multiple built-in slide rods 508 are distributed inside the push spring 510. The end of the push spring 510 away from the rounded clamping plate 509 is fixedly connected to the inner wall of the concave slot 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 relative to each other 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 component 308 on the inner smooth 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 at the top to rotate. When the inner smooth circular plate 307 rotates, it drives the corrugated ring piece 3082 at the top to rotate at high speed. At this time, the circular top block 3081 connected to the inner smooth circular plate 307 in rotation does not rotate. When the corrugated ring piece 3082 rotates at high speed, it is gradually stretched outwards towards the direction of 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 inwardly to a position away from the annular rubber pad 306. When the corrugated ring piece 3082, which has restored its 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, and by setting a conical thorn block 3085 at the bottom of the side connecting rod 3084 to always align with the corrugated groove 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 is adsorbed and fixed on the electric roller 303, the flange plate is placed between the two rounded clamping plates 509 in the concave slot 506, and then The servo motor 502 is then started to drive the threaded long rod 503 to rotate. When the threaded long rod 503 rotates, it drives the two built-in slides 504 in the rectangular frame plate 501 to move toward the flange plate. When the built-in slide 504 moves, it drives the square clamp 505 on one side to move. The movement of the square clamp 505 drives the built-in sliding rod 508, the rounded clamp 509 and the pushing spring 510 in the concave slot 506 to move together. When the rounded clamp 509 contacts the flange plate, the flange plate is gradually inserted between the two rounded clamps 509 along the rounded surface. The rounded surface on the top of the rounded clamp 509 makes it easy for the flange plate to be inserted between the two rounded clamps 509 through the rounded sliding surface. When the flange plate is inserted between the two rounded clamps 509, the pushing spring 510 pushes the rounded clamp 509 through the stretching force to clamp and fix the flange plate so that it is always aligned parallel to the two sides of the web. The rounded clamp 509 elastically connected to the pushing spring 510 is provided in the concave slot 506. To adjust and clamp flange plates of different thicknesses, when the flange plate is inserted between the two rounded corner clamps 509, the rounded corner clamps 509 are pushed to the sides. When the rounded corner clamps 509 move to the 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. By providing a built-in circular groove 507 in the concave slot 506, the built-in slide bar 508 is facilitated to move and the rounded corner clamp 509 is slidably limited by the built-in slide bar 508.

[0049] 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 it, and the clamping mechanism 5 is adjusted by the large electric slide 2 to move it to a position where it fits and docks with both sides of the web plate. 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 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 mechanism 5 is used to release the clamping of the flange plate, and then the unloading mechanism is driven by the hydraulic push rod 4 The feeding 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 slid and unloaded by rolling contact. The web to be welded is placed on the electric roller 303 on the storage platform 301, and the two sides of the web are adjusted to a position parallel to 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 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 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 provided 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 relative to 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 together with it 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. 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 arranging a 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, the H-shaped steel column slides and unloads from the storage platform 301 by rolling contact. At this time, the driving motor 310 is started to drive the linkage rod 309 to rotate.The rotation of the linkage rod 309 drives the inner smooth circular plate 307 at the top to rotate. When the inner smooth circular plate 307 rotates, it drives the corrugated ring piece 3082 at the top to rotate at high speed. At this time, the circular top block 3081 connected to the inner smooth circular plate 307 does not rotate. When the corrugated ring piece 3082 rotates at high speed, it is gradually stretched outward near the annular rubber pad 306 by the 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 reduced by the driving motor 310. The rotation speed of the small corrugated ring piece 3082 is small. When the rotation speed of the corrugated ring piece 3082 becomes small, 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, and the corrugated ring piece 3082 restored to the 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 arranging the conical thorn block 3085 at the bottom of the side connecting rod 3084, 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, which is always aligned with the corrugated groove 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, 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 slides 504 in the rectangular frame plate 501 to move toward the flange plate. When the built-in slide 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 pushing 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. By arranging the rounded clamping plate 509 elastically connected to the pushing spring 510 in the concave card groove 506, the flange plates of different thicknesses can be adjusted and clamped. 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 pushing spring 510 is compressed and drives the built-in sliding rod 508 on one side to slide in the built-in circular groove 507. By providing the built-in circular groove 507 in the concave card groove 506, the built-in sliding rod 508 is facilitated to move and the built-in sliding rod 508 is used to limit the sliding of the rounded clamping plate 509.
