Description

Technical Field

[0001] The present invention belongs to the technical field of welding equipment, and particularly relates to a welding positioning device for a climbing frame net grid. Background Art

[0002] As a key temporary support structure in high-rise building construction, the grid of a climbing frame net is usually composed of longitudinal and transverse steel pipes and diagonal bracing pipes. During the welding process, the precise positioning and stable clamping of each steel pipe are the core links to ensure the stability of the grid structure and the welding quality. In the prior art, although various welding positioning devices have been proposed, there are still significant deficiencies. For example, the patent with the publication number CN219274938U discloses a scheme for fixing steel pipes through the limiting protrusions of a frame base. Although it simplifies the process of placing steel pipes, it relies on static limiting blocks and manual pressing mechanisms, and has the following problems:

[0003] Insufficient clamping force and poor uniformity: Traditional clamps mostly use one-way pressing or fixed limiting blocks, and it is difficult to apply uniform pressure to the steel pipes around the grid with complex shapes at the same time, resulting in the displacement of steel pipes during welding, which may cause defects such as virtual welding or incomplete penetration.

[0017] A welding positioning device for a climbing frame net grid of the present invention:

[0018] 1. For this welding positioning device of the climbing frame net grid, when welding the climbing frame net body, the staff first place the steel pipes used to form the climbing frame net body on the top surface of the steel pipe positioning frame and arrange the steel pipes into the shape of the climbing frame net body. Then, start the first servo motor, which drives the rotating plate to rotate 90°. The rotation of the rotating plate makes the guide rod move along the predetermined trajectory of the arc-shaped guide groove, so that the guide rod pulls the clamping frame towards the steel pipe. The clamping frame drives the clamping positioning plate to position and clamp the steel pipes around the climbing frame net body, thereby improving the accuracy of the positions of the steel pipes around the climbing frame net body and enhancing the quality of the climbing frame net body.

[0019] 2. For this welding positioning device of the climbing frame net grid, during the clamping process of the steel pipes around the climbing frame net body, the clamping frame pulls the push-pull plate to move. Since the eccentric rod slides in the flipping notch, at the same time, the flipping notch pulls the eccentric rod and the eccentric block to rotate around the rotating rod as the axis, so that the rotating rod rotates 180°. After the rotating rod rotates, it drives the pressing connecting rod and the pressing plate to move towards the steel pipe. Finally, the pressing plate applies pressure to the steel pipe to complete the pressing operation, ensuring firm clamping and guaranteeing that the climbing frame net body will not fall during the flipping process. During the clamping process, the clamping frame pulls the V-shaped moving plate to move, making it move along the predetermined direction. The V-shaped moving plate restricts the guiding slide rod through the inclined groove, making the guiding slide rod move along the inclined groove direction. The movement of the guiding slide rod drives the clamping plate to approach the middle steel pipe of the climbing frame net body. Finally, the clamping plate completes the clamping of the middle steel pipe of the climbing frame net body.

[0020] 3. For this welding positioning device of the climbing frame net grid, the push-pull plate pushes the extrusion column and the extrusion disc into the extrusion cylinder. The extrusion column drives the extrusion disc into the extrusion cylinder to compress the air in the cylinder. The compressed gas is discharged through the jet pipe and blows towards the welding area in a directed manner. The high-pressure gas ejected can effectively remove the dust near the welding area, thus avoiding the influence of dust on the welding quality.

[0021] 4. For this welding positioning device of the climbing frame net grid, the second servo motor drives the positioning frame to flip 180°, making the other side of the climbing frame net body face upwards for welding the other side of the climbing frame net body. After welding, the first servo motor drives the rotating plate to reset, releasing the clamping of the climbing frame net body by the positioning mechanism, the pressing mechanism and the clamping mechanism, and pushing the climbing frame net body through the stripping cylinder, so that it disengages from the equipment and falls onto the conveyor. The entire process from flipping, welding, resetting to stripping is automatically completed by the equipment without manual intervention, improving the production efficiency of the climbing frame net body.

[0022] 5. When the climbing frame net body is detached, the second servo motor drives the positioning frame to continue to flip 180°. During the process of returning to the initial position, since the lifting rod slides in the lifting groove, when the lifting rod passes through the V-shaped groove in the lifting groove, the cleaning action is triggered. The lifting rod pulls the cleaning rod to move on the limit groove plate through the pull rod, and the cleaning rod drives the brush to clean the surface of the positioning frame. At the same time, because the gear meshes with the toothed plate, the gear meshing with the toothed plate makes the brush rotate, enhancing the cleaning effect, which can effectively remove welding slag and other residues. Regularly cleaning the welding slag can reduce the surface wear of the positioning frame, improve the service life of the equipment, and ensure that the clamping surface is clean without residue.

Detailed implementation manners

[0037] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

A conveyor 102 is fixedly connected to the bottom of the flipping frame 101. A fixing plate 103 is fixedly connected to the side wall of the conveyor 102. A welding robotic arm 104 is fixedly connected to the top of the fixing plate 103. It further includes:

[0039] A placing mechanism 2. The placing mechanism 2 includes a flipping shaft 201 rotatably connected to the through hole of the flipping frame 101. One end of the flipping shaft 201 is fixedly connected to a positioning frame 202. A climbing frame net body 21 is arranged on the top of the positioning frame 202. This is set so that the staff can place the steel pipes used to form the climbing frame net body 21 on the top surface of the steel pipe positioning frame 202 and arrange the steel pipes into the shape of the climbing frame net body 21. A vertical and horizontal rod positioning block 203 is fixedly connected to the top of the positioning frame 202. An inclined rod positioning block 204 is fixedly connected to the top of the positioning frame 202;

[0040] Positioning mechanism 3. The positioning mechanism 3 includes a support frame 301 fixedly connected to the bottom of the positioning frame 202. The inner wall of the support frame 301 is fixedly connected with a first servo motor 302. The output end of the first servo motor 302 is fixedly connected with a rotating plate 303. An arc-shaped guiding groove 304 is formed in the top of the rotating plate 303. A guiding rod 305 is slidably connected to the inner wall of the arc-shaped guiding groove 304. A clamping frame 306 is fixedly connected to the outer wall of the guiding rod 305. A limiting groove 31 is formed in the top of the positioning frame 202. The inner wall of the limiting groove 31 is slidably connected to the side wall of the clamping frame 306. A clamping and positioning plate 307 is fixedly connected to the top of the clamping frame 306. This is set up to start the first servo motor 302, which drives the rotating plate 303 to rotate 90°. The rotation of the rotating plate 303 makes the guiding rod 305 move along the predetermined trajectory of the arc-shaped guiding groove 304, so that the guiding rod 305 pulls the clamping frame 306 towards the steel pipe. The clamping frame 306 drives the clamping and positioning plate 307 to position and clamp the steel pipes around the climbing frame net body 21, thereby improving the accuracy of the positions of the steel pipes around the climbing frame net body 21 and enhancing the quality of the climbing frame net body 21. A diagonal rod clamping plate 308 is fixedly connected to the top of the clamping frame 306. This is set up to make the clamping frame 306 drive the diagonal rod clamping plate 308 to clamp the diagonal pipes of the climbing frame net body 21.

[0041] As Figures 6 to 8 shown, a pressing mechanism 4 is arranged on the outer wall of the vertical and horizontal rod positioning block 203. The pressing mechanism 4 includes a rotating rod 401 rotatably connected to the through hole of the vertical and horizontal rod positioning block 203. A pressing connecting rod 402 is fixedly connected to the outer wall of the rotating rod 401. A pressing plate 403 is fixedly connected to the side wall of the pressing connecting rod 402. An eccentric block 404 is fixedly connected to the right end of the rotating rod 401. An eccentric rod 405 is fixedly connected to the side wall of the eccentric block 404. A push-pull plate 41 is fixedly connected to the top of the clamping frame 306. A flipping groove 42 is formed in the side wall of the push-pull plate 41. The inner wall of the flipping groove 42 is slidably connected to the outer wall of the eccentric rod 405. This is set up to make the clamping frame 306 pull the push-pull plate 41 to move. Since the eccentric rod 405 slides in the flipping groove 42, at the same time, the flipping groove 42 pulls the eccentric rod 405 and the eccentric block 404 to rotate around the rotating rod 401 as the axis, so that the rotating rod 401 rotates 180°. After the rotating rod 401 rotates, it drives the pressing connecting rod 402 and the pressing plate 403 to move towards the steel pipe. Finally, the pressing plate 403 applies pressure to the steel pipe to complete the pressing operation.

[0042] The outer wall of the clamping frame 306 is provided with a clamping mechanism 5. The clamping mechanism 5 includes a V-shaped moving plate 501 fixedly connected to the bottom of the clamping frame 306. An inclined groove 502 is formed in the bottom of the V-shaped moving plate 501. A guiding slide rod 503 is slidably connected to the inner wall of the inclined groove 502. The top end of the guiding slide rod 503 is fixedly connected to a clamping plate 504. A clamping notch 51 is formed in the top of the positioning frame 202. A translation slide rod 505 is fixedly connected to the inner wall of the clamping notch 51. The outer wall of the translation slide rod 505 is slidably connected to the inner wall of the clamping plate 504. This is set so that the clamping frame 306 pulls the V-shaped moving plate 501 to move during the clamping process, making it move along a predetermined direction. The V-shaped moving plate 501 restricts the guiding slide rod 503 through the inclined groove 502, causing the guiding slide rod 503 to move along the direction of the inclined groove 502. The movement of the guiding slide rod 503 drives the clamping plate 504 to approach the middle steel pipe of the climbing frame net body 21. Finally, the clamping plate 504 completes the clamping of the middle steel pipe of the climbing frame net body 21.

[0043] As Figures 10 to 12 shown, a cleaning mechanism 8 is provided on the side wall of the flipping frame 101. The cleaning mechanism 8 includes a connecting frame 801 fixedly connected to the side wall of the flipping frame 101. A servo motor II 802 is fixedly connected to the inner wall of the connecting frame 801. The output end of the servo motor II 802 is fixedly connected to the end of the flipping shaft 201. A fixing block 803 is fixedly connected to the top of the positioning frame 202. A limiting groove plate 804 is fixedly connected to the top of the fixing block 803. A cleaning rod 805 is slidably connected to the inner wall of the limiting groove plate 804. A brush 806 is fixedly connected to the outer wall of the cleaning rod 805. A gear 807 is fixedly connected to the outer wall of the cleaning rod 805. A rack 808 is meshed with the side wall of the gear 807. The bottom of the rack 808 is fixedly connected to the top of the fixing block 803. This is set so that the cleaning rod 805 drives the brush 806 to clean the surface of the positioning frame 202. At the same time, because the gear 807 is meshed with the rack 808, the gear 807 and the rack 808 are meshed to make the brush 806 rotate, enhancing the cleaning effect.

[0044] A pull rod 809 is rotatably connected to the outer wall of the cleaning rod 805. One end of the pull rod 809 away from the cleaning rod 805 is rotatably connected to a lifting pull rod 81. A through hole of the outer wall of the lifting pull rod 81 is slidably connected to an L-shaped slide rod 82. The bottom end of the L-shaped slide rod 82 is fixedly connected to the side wall of the positioning frame 202. A limiting plate 83 is fixedly connected to the side wall of the flipping frame 101. A lifting groove 84 is formed in the side wall of the limiting plate 83. The inner wall of the lifting groove 84 is slidably connected to the outer wall of the lifting pull rod 81. This is set so that the cleaning action is triggered when the lifting pull rod 81 passes through the V-shaped groove in the lifting groove 84.

[0045] The bottom of the positioning frame 202 is fixedly connected to a fixed frame 701. Inside the fixed frame 701, a stripping cylinder 702 is fixedly connected. The output end of the stripping cylinder 702 is in contact with the bottom of the climbing frame net body 21.

[0046] As Figure 9 shown, before welding, if there is dust at the welding joint, it may decompose or volatilize at high temperature, generating gas that enters the weld and forms pores; some dust particles may also be wrapped in the weld to form inclusions. Dust will interfere with the fluidity and stability of the welding molten pool, resulting in an irregular or discontinuous weld shape. The dust layer will hinder heat transfer, making it difficult for the welding area to reach the ideal melting temperature and affecting the welding effect. A jetting mechanism 6 is arranged on the side wall of the push-pull plate 41. The jetting mechanism 6 includes an extrusion column 601 fixedly connected to the side wall of the push-pull plate 41. One end of the extrusion column 601 away from the push-pull plate 41 is fixedly connected to an extrusion disc 602. The side wall of the positioning frame 202 is fixedly connected to an extrusion cylinder 603. The inner wall of the extrusion cylinder 603 is slidably connected to the outer wall of the extrusion disc 602. A jetting pipe 604 is communicated with the side wall of the extrusion cylinder 603. This is set such that when the push-pull plate 41 pushes the extrusion column 601 and the extrusion disc 602 into the interior of the extrusion cylinder 603, the extrusion column 601 drives the extrusion disc 602 into the extrusion cylinder 603, compressing the air inside the cylinder. The compressed gas is discharged through the jetting pipe 604 and is directed to blow at the welding joint. The ejected high-pressure gas can effectively remove the dust near the welding area, thus avoiding the influence of dust on the welding quality.

[0047] The working principle of a welding positioning device for a climbing frame net grid: When in use, when welding the climbing frame net body 21 is required, the staff first places the steel pipes used to form the climbing frame net body 21 on the top surface of the steel pipe positioning frame 202 and arranges the steel pipes into the shape of the climbing frame net body 21. Then, start the servo motor 302, which drives the rotating plate 303 to rotate 90°. The rotation of the rotating plate 303 causes the guide rod 305 to move along the predetermined trajectory of the arc-shaped guide groove 304, so that the guide rod 305 pulls the clamping frame 306 towards the steel pipe direction. The clamping frame 306 drives the clamping positioning plate 307 to position and clamp the steel pipes around the climbing frame net body 21, thereby improving the accuracy of the positions of the steel pipes around the climbing frame net body 21 and enhancing the quality of the climbing frame net body 21.

[0048] During the clamping process of the steel pipes around the main body 21 of the climbing frame net, the clamping frame 306 pulls the push-pull plate 41 to move. Since the eccentric rod 405 slides in the flipping notch 42, at the same time, the flipping notch 42 pulls the eccentric rod 405 and the eccentric block 404 to rotate around the rotating rod 401 as the axis, so that the rotating rod 401 rotates 180°. After the rotating rod 401 rotates, it drives the pressing connecting rod 402 and the pressing plate 403 to move towards the steel pipe. Finally, the pressing plate 403 applies pressure to the steel pipe to complete the pressing operation, ensuring firm clamping and guaranteeing that the main body 21 of the climbing frame net will not fall during the flipping process. During the clamping process, the clamping frame 306 pulls the V-shaped moving plate 501 to move, making it move along a predetermined direction. The V-shaped moving plate 501 restricts the guiding slide rod 503 through the inclined slot 502, so that the guiding slide rod 503 moves along the direction of the inclined slot 502. The movement of the guiding slide rod 503 drives the clamping plate 504 to approach the middle steel pipe of the main body 21 of the climbing frame net. Finally, the clamping plate 504 completes the clamping of the middle steel pipe of the main body 21 of the climbing frame net;

[0049] The push-pull plate 41 pushes the extrusion column 601 and the extrusion disk 602 to move into the inside of the extrusion cylinder 603. The extrusion column 601 drives the extrusion disk 602 to enter the extrusion cylinder 603, compresses the air in the cylinder, and the compressed gas is discharged through the jet pipe 604 and blows towards the welding place in a targeted manner. The high-pressure gas ejected can effectively remove the dust near the welding area, thus avoiding the influence of dust on the welding quality;

[0050] The servo motor two 802 drives the positioning frame 202 to flip 180°, making the other side of the main body 21 of the climbing frame net face upwards, and welding the other side of the main body 21 of the climbing frame net. After the welding is completed, the servo motor one 302 drives the rotating plate 303 to reset, releases the clamping of the main body 21 of the climbing frame net by the positioning mechanism 3, the pressing mechanism 4 and the clamping mechanism 5, and pushes the main body 21 of the climbing frame net through the stripping cylinder 702, so that it disengages from the equipment and falls onto the conveyor 102. The whole process from flipping, welding, resetting to stripping is automatically completed by the equipment without manual intervention, improving the production efficiency of the main body 21 of the climbing frame net;

[0051] When the main body 21 of the climbing frame net is disengaged, the servo motor two 802 drives the positioning frame 202 to continue to flip 180°. During the return to the initial position, since the lifting rod 81 slides in the lifting slot 84, when the lifting rod 81 passes through the V-shaped slot in the lifting slot 84, the cleaning action is triggered. The lifting rod 81 pulls the cleaning rod 805 to move on the limit slot plate 804 through the pull rod 809. The cleaning rod 805 drives the brush 806 to clean the surface of the positioning frame 202. At the same time, since the gear 807 meshes with the toothed plate 808, and the gear 807 meshes with the toothed plate 808 to make the brush 806 rotate, enhancing the cleaning effect, which can effectively remove the welding slag and other residues. Regularly cleaning the welding slag can reduce the surface wear of the positioning frame 202, improve the service life of the equipment, and ensure that the clamping surface is clean without residue.

[0052] It should be noted that the specific model specifications of the first servo motor 302, the second servo motor 802, and the stripping cylinder 702 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field.

[0053] The principles of the first servo motor 302, the second servo motor 802, and the stripping cylinder 702 are clear to those skilled in the art and will not be described in detail here.

Those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present invention.
