Detailed implementation manners

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] Embodiment, as Figures 1 - 2 shown, the embodiment of the present invention provides a steel structure welding and processing device, including a workbench 1, two auxiliary fixing mechanisms 3 installed at the front and rear ends of the workbench 1 for fixing and aligning the steel structure body 6, and a linkage welding mechanism 4 installed at the upper end of the workbench 1 for assisting in squeezing and aligning and welding the two steel structure bodies 6. At the midpoint on one side of the upper end surface of the workbench 1, an extrusion mechanism 5 for pushing and squeezing the midpoint of the outer wall of the steel structure body 6 is fixedly provided. A limiting block is fixedly provided at a position symmetrical to the extrusion mechanism 5 at the midpoint on the other side of the upper end surface of the workbench 1. A guide rail groove 8 is opened on one side of the upper end surface of the workbench 1, and a driving component 7 is installed inside the guide rail groove 8. The driving component 7 is used to drive the linkage welding mechanism 4 to perform reciprocating displacement in the front and rear directions. The driving component 7 includes a driving rod and a servo motor. The driving rod is a threaded driving rod and is fixed to the output end of the servo motor.

[0017] Specifically, after placing the two steel structure bodies 6 on the upper end of the workbench 1 and aligning and splicing them, the two auxiliary fixing mechanisms 3 at the front and rear ends are adjusted to move so as to clamp and fix the heads and tails of the two spliced steel structure bodies 6, thereby achieving the auxiliary fixing effect at the heads and tails; and the limiting block provided on the workbench 1 and the extrusion mechanism 5 symmetrically arranged with the limiting block are located at the middle position of the steel structure body 6, so that the midpoint of the spliced steel structure body 6 can be squeezed, thereby forming a three-point auxiliary fixing effect and ensuring the stability of the steel structure body 6 during welding and processing; at the same time, the driving component 7 is used to drive the linkage welding mechanism 4 to perform automatic front and rear displacement, without manual operation, which is more convenient to use and the linkage welding mechanism 4 has a fast alignment function, and the welding positioning is more accurate.

[0018] Refer to Figures 1 - 4, the auxiliary fixing mechanism 3 includes a second fixing block 303 fixed to the upper end of the workbench 1 and a first movable block 306 slidably arranged on the upper end of the workbench 1 opposite to the second fixing block 303. A linkage plate 302 is fixedly arranged on the rear end face of the second fixing block 303, and a first fixing block 301 is fixedly arranged at the other end of the linkage plate 302. A second guide rod 308 is fixedly arranged on the upper end face of the first movable block 306, and a second movable block 307 is slidably sleeved on the upper end of the second guide rod 308. A first guide rod 305 is installed on the opposite sides of the second fixing block 303 and the first movable block 306, and the first movable block 306 slidably penetrates through the first guide rod 305. A connecting plate 304 is fixedly arranged on one side of the upper end face of the second fixing block 303. A moving rod 309 is fixedly arranged on one side of the lower end face of the second movable block 307. One end of the moving rod 309 is threadedly penetrated with an adjusting screw rod, and the other end of the adjusting screw rod is rotatably arranged at one end of the connecting plate 304 through a bearing; Specifically, that is, during use, the rotation of the adjusting screw rod drives the moving rod 309 threadedly connected thereto to move. During the process of being pulled, the moving rod 309 will drive the second movable block 307 to make an oblique displacement until it continuously approaches the corner at the upper end of the steel structure body 6 and fits completely, thus achieving the auxiliary fixing effect. Since the second movable block 307 is sleeved on the second guide rod 308 and the lower end of the second guide rod 308 is fixed to the first movable block 306, and the first movable block 306 is also slidably sleeved on the first guide rod 305 and can slide horizontally. At this time, when the second movable block 307 needs to make an oblique displacement, it will lift along the second guide rod 308 and pull the first movable block 306 to move horizontally on the first guide rod 305, thereby realizing the oblique displacement of the second guide rod 308 and the horizontal displacement of the first movable block 306, and finally realizing the extrusion fixation of the outer wall of the steel structure body 6.

[0019] Refer to Figures 3 - 4 , a housing 3010 is fixedly installed on the outside of the adjusting screw rod at one end of the connecting plate 304. A second bevel gear 3013 is fixedly sleeved on the outside of the adjusting screw rod inside the housing 3010. A micro motor 3012 is fixedly arranged on the bottom end face inside the housing 3010, and a first bevel gear 3011 meshing with the second bevel gear 3013 is installed at the output end of the micro motor 3012; Specifically, that is, the start of the micro motor 3012 can drive the first bevel gear 3011 at the output end to rotate. Since the first bevel gear 3011 meshes with the second bevel gear 3013, the second bevel gear 3013 rotates accordingly at this time. After the second bevel gear 3013 rotates, it drives the adjusting screw rod connected thereto to rotate, thereby realizing the pulling effect of the moving rod 309 threadedly sleeved with the adjusting screw rod.

[0020] Refer to Figures 3 - 4, both the first fixed block 301 and the second movable block 307 are L-shaped. The distance between the first fixed block 301 and the second fixed block 303 matches the thickness of the steel structure body 6. At the front and rear ends of the upper end surface of the workbench 1, away from the guide rail groove 8, sliding grooves 2 are provided. The lower end of the first movable block 306 is slidably embedded in the sliding groove 2; Specifically, the lower end of the first movable block 306 is embedded into the inside of the sliding groove 2 for sliding, providing an auxiliary guiding function and a limiting effect. The L-shaped structures of the first fixed block 301 and the second movable block 307 can better match the corners of the steel structure body 6 to complete the semi-encircling limiting effect.

[0021] Refer to Figures 5 - 7 , the linkage welding mechanism 4 includes a linkage seat 401 threadedly sleeved on the outside of the threaded drive rod. The lower end of the linkage seat 401 is embedded in the guide rail groove 8. A second mounting block 4010 is fixedly provided on one side of the linkage seat 401. A second roller 409 is rotatably connected to the lower end of the second mounting block 4010. A moving seat 403 is fixedly provided on the side of the second mounting block 4010 away from the linkage seat 401. A screw rod 4011 is rotatably installed inside the moving seat 403 through a bearing seat, and a third bevel gear 4012 is fixedly provided at one end of the screw rod 4011. An adjusting rod 402 is rotatably provided on the upper end surface of the moving seat 403 through a bearing, and a fourth bevel gear 4013 meshing with the third bevel gear 4012 is provided at the lower end of the adjusting rod 402. A push plate 404 is threadedly sleeved on the outside of the screw rod 4011. A first mounting block 406 is fixedly provided on one side of the push plate 404, and a first roller 405 is rotatably provided at the lower end of the first mounting block 406. A first steering plate 407 is rotatably installed on the upper end surface of the push plate 404. A second steering plate 408 is rotatably installed on one side of the upper end surface of the moving seat 403; Specifically, during use, the rotation of the threaded drive rod drives the linkage seat 401 threadedly connected to the outside to displace in the front and rear directions. Since the lower end of the linkage seat 401 is embedded in the guide rail groove 8, the rotation of the linkage seat 401 can be avoided. When the linkage seat 401 displaces back and forth, the entire linkage welding mechanism 4 installed together with the linkage seat 401 also moves back and forth together; After the two steel structure bodies 6 are installed and fixed, the second roller 409 located at the lower end of the second installation block 4010 fits against the outer wall of the left steel structure body 6. While the first roller 405 located at the lower end of the first installation block 406 is being adjusted by turning the adjustment rod 402, the fourth bevel gear 4013 at the lower end drives the third bevel gear 4012 to rotate. Subsequently, the screw 4011 rotates following the third bevel gear 4012. When the screw 4011 rotates, the push plate 404 sleeved on the outer thread moves horizontally. That is, at this time, the first installation block 406 connected to the push plate 404 is pulled and moves horizontally, thereby driving the first roller 405 to continuously approach and fit against the outer wall of the steel structure body 6 spliced on the right side. And because both rollers are rotatably installed, they roll and translate while fitting against the outer wall of the steel structure during the movement.

[0022] Referring to Figures 5 - 7 , one end of the first steering plate 407 is rotatably connected to one end of the second steering plate 408. At the lower end position of the connection point between the first steering plate 407 and the second steering plate 408, a welding machine 4014 is fixedly arranged, and a welding rod is installed at the lower end of the welding machine 4014. The first roller 405 and the second roller 409 are respectively located on the outer walls of both sides of the two steel structure bodies 6, and the welding machine 4014 is located at the splicing seam of the two steel structure bodies 6; Specifically, when the push plate 404 moves horizontally, since one end of the first steering plate 407 is rotatably arranged on the moving seat 403 and the other end is rotatably connected to the second steering plate 408, and one end of the second steering plate 408 is rotatably installed on the push plate 404. That is, when the push plate 404 moves horizontally, the included angle between the first steering plate 407 and the second steering plate 408 changes, and the connection point between the two moves continuously. And because the welding machine 4014 is arranged at the lower end of the connection point, the welding machine 4014 continuously moves towards the splicing seam of the two steel structures. Finally, when the first roller 405 fits against the outer wall of the right steel structure, the position of the welding machine 4014 changes and stops at the position of the splicing seam. At this time, the welding machine 4014 completes the horizontal welding work from front to back under the effect of the front and back pushing of the welding rod at the lower end and the driving assembly 7.

[0023] Referring to Figures 5 - 7 , the horizontal length of the moving seat 403 is less than the horizontal length after the two steel structure bodies 6 are spliced and less than the minimum horizontal length of the inner diameter of the auxiliary fixing mechanism 3; Specifically, ensure that the entire linkage welding mechanism 4 can pass smoothly during the front and back displacement process, and ensure the integrity of the welding of the entire splicing seam.

[0024] Referring to Figures 1 - 2, the extrusion mechanism 5 includes a fixing plate 501 fixed to the upper end of the workbench 1. One side of the fixing plate 501 is threadedly penetrated with a threaded rod 503. One end of the threaded rod 503 is rotatably connected to an extrusion plate 505. A guiding groove 504 is formed on the upper end surface of the workbench 1 on one side of the fixing plate 501. The lower end of the extrusion plate 505 is slidably embedded in the guiding groove 504. A twisting block 502 is fixedly arranged at the end of the threaded rod 503 away from the extrusion plate 505; Specifically, during use, by rotating the twisting block 502 to drive the threaded rod 503 to rotate, the threaded rod 503 continuously moves to the left during rotation and pushes the extrusion plate 505 connected to the left to extrude the outer wall of the steel structure body 6, thereby achieving an auxiliary fixing effect. Since the extrusion plate 505 is rotatably connected to the threaded rod 503 and its lower end is restricted in the guiding groove 504, the extrusion plate 505 can be prevented from rotating and causing inability to displace.

[0025] Working principle: During use, first place one of the steel structure bodies on the upper end of the workbench and make one side outer wall thereof closely adhere to the limiting block. At the same time, the front and rear ends of the steel structure body are embedded inside the first fixing block and the second fixing block of the auxiliary fixing mechanism arranged on the upper end of the workbench. Then place another steel structure body on one side of the steel structure body to splice it with the steel structure body. Subsequently, start the micro-motors built in the two auxiliary fixing mechanisms. The micro-motors drive the first bevel gears at the output ends to drive the second bevel gears and the adjusting screws to rotate. The adjusting screws are threadedly connected to the moving rods and the moving rods are connected to the second movable blocks, thereby pulling the second movable blocks to move. At the same time, since the second movable blocks and the first movable blocks are linked by the second guiding rods, the two movable blocks move together, thereby realizing the auxiliary positioning and extrusion fixation of the steel structure body, making the steel structure body and the steel structure body closely fit and splice; at the same time, the outer wall of the steel structure body is extruded and pushed by the extrusion mechanism. Since the extrusion mechanism is located at the midpoint position, the three-point auxiliary extrusion fixation effect of head-middle-tail is achieved; Subsequently, adjust the linkage welding mechanism at the upper end so that it is located at the splicing seam of the two steel structure bodies. By turning the adjusting rod, drive the third bevel gear at the output end to drive the fourth bevel gear to rotate. Subsequently, the screw rotates to promote the movement of the push plate sleeved with the outer thread. During the movement of the push plate, it will continuously drive the first roller at the lower end of the first mounting block to approach and fit against the outer wall of the second steel structure body. There is a second roller attached to the outer wall of the first steel structure body, enabling it to move forward and backward more smoothly. And under the continuous displacement of the push plate, the first turning plate and the second turning plate at the upper end rotate, and the connection point between the first turning plate and the second turning plate continuously approaches the splicing seam. When the first roller approaches and fits against the outer wall of the second steel structure body, the connection point between the first turning plate and the second turning plate is just located at the splicing seam. At this time, the welding machine at the lower end of the connection point starts to work and performs longitudinal displacement under the action of the driving mechanism, finally completing the welding work at the splicing seam of the two steel structure bodies.
