Description

Technical Field

[0001] The present invention relates to a welding tooling, specifically a positioning and anti-deviation welding tooling for the splicing of steel structures, belonging to the technical field of welding tooling. Background Art

[0002] Steel structures have the advantages of high strength, good toughness, good seismic performance, fast construction speed, modular production, etc., and are very suitable for the development needs of modern engineering structures towards high-rise, large-span and heavy-load. The engineering applications are increasing day by day. And with the widespread construction of super high-rise buildings, large-span buildings and bridges, heavy-load industrial plants and special structures, steel structures are widely used.

[0003] However, in the on-site installation of steel structures, it is necessary to carry out on-site assembly and welding according to the actual steel structure dimensions on site. Since common steel structures such as mouth-shaped, day-shaped, and eye-shaped have a long length, the middle part of the steel beam profile is prone to deformation and bending. There is a large gap between the bent part and the steel structure during welding, resulting in inability to weld. The conventional operation is to use multiple screw clamps to clamp and fix the corresponding steel beam profiles, so that the bent part fits against the steel structure. However, when using this kind of welding anti-deviation tooling, the bent part of the steel beam profile needs to be found manually, and then multiple clamps are required for fixation, which is prone to deviation and requires a long working time. Moreover, multiple clamps block the welding area, which means that during welding, the operator needs to disassemble multiple clamps near the welding equipment position, which is relatively dangerous.

[0016] The present invention provides a steel structure joint positioning and anti-deviation welding tool, which has the following beneficial effects:

[0017] 1. The anti-bias welding tooling at the joint of the steel structure is used. The steel structure profile 2 is arranged between multiple pressing frames and side pressure plates, and the top and bottom are supported by the upper pressure plate and the bottom plate. The steel structure profile 2 is supported and limited by the side pressure structure. The steel structure profile 1 falls to the top of the bottom plate. The steel structure profile 1 changes from a state supported by multiple rotating shafts to a state of falling to the top of the bottom plate, which increases the friction force on the steel structure profile 1 and reduces the possibility of shaking during the welding process of the steel structure profile 1 and the two steel structure profiles 2. The contact position of the steel structure profile 1 and the steel structure profile 2 is subjected to the force applied by the hydraulic cylinder 5 in real time to avoid deformation of the contact position of the steel structure profile 1 and the steel structure profile 2, thereby ensuring the stability of the steel structure profile 1 and the steel structure profile 2 in the process of welding to form the steel structure. The one ends of the steel structure profile 1 and the steel structure profile 2 are respectively limited by the blocking frame and the blocking plate to ensure the accurate positioning of the steel structure profile 1 and the steel structure profile 2 and the quality of the steel structure forming.

[0018] 2. The anti-bias welding tooling at the joint of the steel structure is positioned. The support frame, clamping frame, clamping plate 1, clamping plate 2 and hydraulic cylinder 3 rise, and the second steel structure profile to be clamped and fixed is lifted to the processing position. The welding positioning tooling composed of the support structure, clamping structure and side pressure structure cooperates with the control panel and welding equipment to meet the one-time processing and forming of the "R"-shaped steel structure, reducing the cost investment required for welding processing of more complex steel structures such as "R"-shaped, "M"-shaped and "I"-shaped.

[0019] 3. The anti-bias welding tooling is positioned at the joint of the steel structure. When the dual-axis motor is working, the two reciprocating screws rotate inside the fixed guide rail, the two sliding blocks move to both sides inside the fixed guide rail, and the hydraulic cylinder 2 fixedly connected to the top of the sliding block moves. Finally, the two hydraulic cylinders move to both sides of the top of the supporting structure, leaving a channel for the steel structure to leave the top of the supporting structure.

[0020] 4. The anti-bias welding tooling is positioned at the joint of the steel structure, and the working hydraulic cylinder five drives the side pressure plate to reset. Since the pressing frame has been moved up to the top of the steel structure profile two at this time, the resetting of the side pressure plate will not affect the steel structure profile two, and the side pressure plate will pull the trapezoidal plate through the pressing frame, and the curved surface of the trapezoidal plate moves toward the roller part to lift the roller part, and the roller part lifts the U-shaped frame. When the side pressure plate is reset, the U-shaped frame and the rotating shaft connected to the rotation inside the U-shaped frame are lifted up, and multiple rotating shafts that can rotate lift the steel structure to reduce the movement resistance of the steel structure. The linkage between the side pressure structure and the supporting structure reduces the resistance of the steel structure to move away from the top of the supporting structure, which facilitates the movement of the steel structure away from the processing and forming position, reduces the time and difficulty of the steel structure leaving the processing position where complex equipment is set, and reduces the physical and time cost investment of the staff.

DETAILED DESCRIPTION

[0036] The side pressure structure 3 includes a hydraulic cylinder 5 33 and a side pressure plate 31. The top of the side pressure plate 31 is fixedly connected to a hydraulic cylinder 6 38. The top of the hydraulic cylinder 6 38 is fixedly connected to a fixed long plate 39. The top of the fixed long plate 39 is fixedly connected to a plurality of bent rods 310. One end of the bent rod 310 is fixedly connected to a pressing frame 311. The pressing frame 311 is internally rotatably connected to a plurality of drag reduction shafts 312. The top of the side pressure plate 31 is fixedly connected to a plurality of spring-type telescopic rods 34. An upper pressure plate 36 is installed between the plurality of spring-type telescopic rods 34. The top of the upper pressure plate 36 close to the fixed long plate 39 is fixedly connected to a plurality of transmission short plates 37.

[0037] The supporting structure 1 includes a base plate 11 and a U-shaped frame 16. A movement cavity 18 is opened on both sides of the top of the base plate 11. A fixed bent plate 111 is arranged inside the movement cavity 18. One end of the fixed bent plate 111 is fixedly connected to the side pressure plate 31, and the other end of the fixed bent plate 111 is fixedly connected to a trapezoidal plate 110. A roller is arranged on the top of the trapezoidal plate 110. A damper 19 is arranged inside the movement cavity 18. One end of the damper 19 and the roller are fixedly connected to the U-shaped frame 16. A plurality of rotating shafts 17 are rotatably connected inside the U-shaped frame 16. Fixed beams 4 are fixedly connected to both sides of the top of the base plate 11.

[0038] Specifically,.

[0039] A blocking frame 14 is arranged on one side of the top of the bottom plate 11 close to the clamping structure 2, and the blocking frame 14 is arranged on the top of the U-shaped frame 16. Storage cavities 12 are opened on both sides of the top of the bottom plate 11, and the two ends of the blocking frame 14 extend to the inside of the two storage cavities 12 respectively. The blocking frame 14 can only move up and down under the guidance of the storage cavity 12, and a hydraulic cylinder 13 is arranged inside one of the storage cavities 12. The hydraulic cylinder 13 is fixedly connected between the blocking frame 14 and the bottom plate 11 to support the blocking frame 14. In the initial use of the welding positioning tooling composed of the supporting structure 1, the clamping structure 2, the side pressure structure 3 and other structures, the hydraulic cylinder 13 is in a working state to lift up the blocking frame 14, and blocking plates 15 are fixedly connected on both sides of the blocking frame 14. At this time, the blocking frame 14 and the two blocking plates 15 are in the upper initial position.

[0040] Then the staff pushes the first steel structure profile 5 from the top of the bottom plate 11 away from the clamping structure 2 to the top of the support structure 1. A U-shaped frame 16 is arranged inside the bottom plate 11, and a plurality of rotating shafts 17 are connected to the inside of the U-shaped frame 16. Figure 4 As shown, the outer top of the rotating shaft 17 is set at the top of the U-shaped frame 16, so the steel structure profile 15 is supported by multiple U-shaped frames 16, reducing the resistance of the steel structure profile 15 to the clamping structure 2. Since the blocking frame 14 is set on one side of the top of the U-shaped frame 16 at this time, the steel structure profile 15 is finally blocked by the blocking frame 14. When the steel structure profile 15 is restricted from moving by the blocking frame 14, the steel structure profile 15 stops pushing and is placed in the position to be processed. Then, the steel structure profile 16 is erected and one side is pressed against the side pressure plate 31, as shown in FIG. Figure 1 As shown, the side pressure plate 31 is pushed toward the clamping structure 2, and when the second steel structure profile 6 is blocked by the blocking plate 15, the pushing of the second steel structure profile 6 is stopped.

[0041] Then, the staff controls the hydraulic cylinder six 38 in the side pressure structure 3 to work through the control panel 9, and the hydraulic cylinder six 38 drives the fixed long plate 39 to move downward. After the fixed long plate 39 moves downward and no longer supports the multiple transmission short plates 37 fixedly connected to the upper pressure plate 36, the bottom of the upper pressure plate 36 loses its supporting force, and the multiple fixed short plates 35 fixedly connected to one side of the upper pressure plate 36 are fixedly installed with two spring-type telescopic rods 34. At this time, the spring-type telescopic rod 34 fixedly connected to the side pressure plate 31 rebounds and drives the fixed short plates 35 and the upper pressure plate 36 fixed by the fixed short plates 35 to move downward, so that the bottom of the upper pressure plate 36 is against the steel structure profile two 6. Figure 1 As shown, at this time, the top of the steel structure profile 26 is limited by the upper pressure plate 36, and the multiple bent rods 310 fixedly connected to the fixed long plate 39 are all set to a U shape, so the pressing frame 311 fixedly connected to the bent rod 310 moves to the side of the upper pressure plate 36 away from the side pressure plate 31 without affecting the short-distance movement of the upper pressure plate 36. The steel structure profile 26 is arranged between the multiple pressing frames 311 and the side pressure plate 31, and the top and bottom are supported by the upper pressure plate 36 and the bottom plate 11. The steel structure profile 26 is supported and limited by the side pressure structure 3.

[0042] According to the above method, another steel structure profile 2 6 is installed together with another side pressure structure 3, and the Figure 1 As shown, two steel structure profiles 2 6 are installed on both sides of steel structure profile 1 5.

[0043] The staff controls the operation of the hydraulic cylinder five 33 in the two side pressure structures 3 through the control panel 9. The mounting seat fixedly connected to the bottom of the outer wall of the hydraulic cylinder five 33 is fixedly connected to the bottom plate 11, so the hydraulic cylinder five 33 extends when working to push the transmission frame 32 fixedly connected at one end to move, and the transmission frame 32 is fixedly connected to the side pressure plate 31, so the side pressure plate 31 moves synchronously, and the two side pressure plates 31 push the two steel structure profiles two 6 to move synchronously toward the middle steel structure profile one 5, thereby achieving the effect of aligning the steel structure profile two 6 with the steel structure profile one 5. Finally, the two steel structure profiles 2 6 clamp the middle steel structure profile 1 5. During this process, the steel structure profile 1 5 is pushed to the middle position of the top of the bottom plate 11, and the movement of the side pressure plate 31 drives the fixedly connected fixed bent plate 111 to move. The L-shaped fixed bent plate 111 will push the trapezoidal plate 110 fixedly connected at one end to move during the movement inside the movement cavity 18. After the trapezoidal plate 110 moves, the roller member contacts a side surface of the trapezoidal plate 110 set as an arc surface. Finally, the bottom of the roller member loses the support of the trapezoidal plate 110, and the bottom of the U-shaped frame 16 to which the roller member is fixed loses support. The U-shaped frame 16 and the rotating shaft 17 rotatably connected inside the U-shaped frame 16 fall into the bottom plate 11. The steel structure profile 15 supported by multiple rotating shafts 17 moves downward synchronously, so that the steel structure profile 15 falls to the top of the bottom plate 11. The steel structure profile 15 changes from a state of being supported by multiple rotating shafts 17 to a state of falling to the top of the bottom plate 11, thereby increasing the friction force on the steel structure profile 15 and reducing the possibility of shaking during the welding process of the steel structure profile 15 and the two steel structure profiles 26. In addition, the contact position of the steel structure profile 15 and the steel structure profile 26 is subjected to the force applied by the hydraulic cylinder 5 33 in real time, thereby avoiding deformation of the contact position of the steel structure profile 15 and the steel structure profile 26, ensuring the stability of the steel structure profile 15 and the steel structure profile 26 in the process of welding to form the steel structure, and ensuring the quality of the steel structure forming.

[0044] Finally, the two steel structure profiles 2 6 pushed by the two hydraulic cylinders 5 33 and the two side pressure plates 31 clamp the steel structure profile 1 5 that falls on the top of the bottom plate 11, and one end of the steel structure profile 1 5 and the steel structure profile 2 6 are respectively limited by the blocking frame 14 and the blocking plate 15 to ensure the accurate positioning of the steel structure profile 1 5 and the steel structure profile 2 6; fixed beams 4 are fixedly connected to both sides of the top of the support structure 1, and a mounting guide rail 8 is installed between the two fixed beams 4, and the mounting guide rail 8 is used to install the welding robot 7, such as Figure 2 As shown, the welding robot 7, the mounting guide rail 8 and other structures constitute the welding equipment, and the welding equipment is controlled by the control panel 9 to perform corresponding work according to the CNC program stored inside. The welding equipment performs welding processing on the gap at the connection between the steel structure profile 1 5 and the steel structure profile 2 6, and welds the steel structure profile 1 5 and the two steel structure profiles 2 6 together.

[0045] Then the staff member holds the second steel structure profile 15, passes the steel structure profile 15 between the two steel structure profiles 26, and inserts one end of the steel structure profile 15 between the clamping frame 27 and the clamping plate 129 in the clamping structure 2. A positioning block 28 is fixedly connected inside the clamping frame 27. Fig. 9 As shown, when one end of the steel structure profile 15 is blocked by the positioning block 28, since the positioning block 28 is set on the top of the blocking frame 14, the end of the second steel structure profile 15 is aligned with the end of the first steel structure profile 15 at the bottom, and then the control panel 9 controls the clamping structure 2 electrically connected to the control panel 9 to work, and the hydraulic cylinder 3 212 in the clamping structure 2 works, and the clamping plate 210 fixedly connected to the bottom of the hydraulic cylinder 3 212 is pushed downward, and the downward clamping plate 210 presses against the second steel structure profile 15 entering between the clamping plate 1 29 and the clamping frame 27, and clamps and fixes the second steel structure profile 15. Then the staff controls the electrically connected hydraulic cylinder 25 to work through the control panel 9. The working hydraulic cylinder 25 lifts the support frame 26 fixed on the top, and the support frame 26, the clamping frame 27, the clamping plate 1 29, the clamping plate 210 and the hydraulic cylinder 3 212 rise, and lift the clamped and fixed second steel structure profile 1 5 to the processing position. Then the control panel 9 controls the welding equipment to work according to the internally stored CNC program, and the welding equipment welds the second steel structure profile 1 5 and the two steel structure profiles 2 6 together.

[0046] When the welding equipment is finished, the welding equipment is reset. At this time, the control panel 9 controls the electrically connected clamping structure 2 to work, and the hydraulic cylinder 214 in the clamping structure 2 works. The extension end of the hydraulic cylinder 214 fixedly connected to the support frame 26 is fixedly connected to the fixed cross plate 215. The support block 213 fixedly connected to the fixed cross plate 215 is arranged at the bottom of the clamping plate 29. The working hydraulic cylinder 214 pulls the support block 213 to move through the fixed cross plate 215, so that the support block 213 leaves the bottom of the clamping plate 29, and the clamping plate 29 is hinged to the support frame 26 through a hinge. As the support block 213 is removed from the bottom, the clamping plate 29 rotates and falls under the influence of gravity. At this time, the second steel structure profile 5 will not affect the up and down movement of the clamping plate 29. Then, the hydraulic cylinder 25 continues to work to push the support frame 26 to rise. After the support frame 26, the clamping frame 27 and the clamping plate 29 rise to the top of the second steel structure profile 5, the control panel 9 controls the electrically connected hydraulic cylinder 4 214 to work and push the support block 213 to reset. The support block 213 lifts the clamping plate 29 to restore it to a state parallel to the bottom surface of the clamping frame 27. Fig.10 shown.

[0047] Subsequently, the staff will continue to operate the third steel structure profile - 5 in the same way as the second steel structure profile - 5 above, so that the first steel structure profile - 5, the second steel structure profile - 5, the third steel structure profile - 5 and the two steel structure profiles - 6 can form a steel structure in the shape of a Chinese character 'Ri'. In this application, the welding positioning tooling composed of the support structure 1, the clamping structure 2 and the side pressing structure 3 cooperates with the control panel 9 and the welding equipment, which can meet the one - time processing and forming of the steel structure in the shape of a Chinese character 'Ri', and reduce the cost input required for the welding processing of relatively complex steel structures such as those in the shapes of a Chinese character 'Ri', 'Mu', and 'Gong'. During this process, the hydraulic cylinder six 38 in the side pressing structure 3 is controlled to work through the control panel 9. The hydraulic cylinder six 38 pushes the fixed long plate 39 to move upward. The fixed long plate 39 drives the pressing frame 311 fixed by multiple bent rods 310 to move upward. The pressing frame 311 moves upward and leaves one side of the steel structure profile - 6, avoiding the influence of the pressing frame 311 on the welding processing and forming of the steel structure. When the fixed long plate 39 moves upward and contacts the transmission short plate 37, the fixed long plate 39 pushes the transmission short plate 37 and the upper pressing plate 36 fixedly connected to the transmission short plate 37 to move upward. The upper pressing plate 36 leaves the top of the steel structure profile - 6, reducing the resistance of the steel structure leaving the top of the support structure 1.

[0048] When the processing of the steel structure is completed, the clamping structure 2 is controlled by the control panel 9 to work again, the double-axis motor 22 in the clamping structure 2 works, and the two output ends of the double-axis motor 22 are fixedly connected with the reciprocating screw 24, one end of the reciprocating screw 24 is rotatably connected to the fixed guide rail 21, when the double-axis motor 22 is working, the two reciprocating screws 24 rotate inside the fixed guide rail 21, and the sliding block 23 installed on the outside of the reciprocating screw 24 through the nut pair is driven by the rotating reciprocating screw 24, and the sliding block 23 that cannot rotate inside the fixed guide rail 21 is driven to reciprocate inside the fixed guide rail 21, and the two sliding blocks 23 move to both sides of the inside of the fixed guide rail 21, and the hydraulic cylinder 25 fixedly connected to the top of the sliding block 23 moves, and finally the two hydraulic cylinders 25 move to both sides of the top of the support structure 1, leaving a channel for the steel structure to leave the top of the support structure 1. The hydraulic cylinder 13 works to pull the blocking frame 14 downward, and the blocking frame 14 drives the blocking plate 15 downward, and the blocking frame 14 and the blocking plate 15 enter the storage cavity 12, so that one side of the steel structure profile 1 5 and the steel structure profile 2 6 loses the blocking. After that, the electrically connected side pressure structure 3 is controlled to work through the control panel 9, and the working hydraulic cylinder 5 33 drives the side pressure plate 31 to reset. Since the pressing frame 311 has moved up to the top of the steel structure profile 2 6 at this time, the reset of the side pressure plate 31 will not affect the steel structure profile 2 6, and the side pressure plate 31 will pull the trapezoidal plate 110 through the pressing frame 311, and the trapezoidal plate 110 moves toward the roller part on the curved surface to lift the roller part, and the roller part lifts the U-shaped frame 16. When the side pressure plate 31 is reset, the U-shaped frame 16 and the rotating shaft 17 rotatably connected inside the U-shaped frame 16 are lifted up, and multiple rotating shafts 17 that can rotate lift the steel structure to reduce the movement resistance of the steel structure. The linkage between the side pressure structure 3 and the supporting structure 1 reduces the resistance of the steel structure moving away from the top of the supporting structure 1, facilitates the movement of the steel structure away from the processing and forming position, reduces the time and difficulty of the steel structure leaving the processing position where complex equipment is set, and reduces the physical strength and time cost investment of the staff.

[0049] In the process of the hydraulic cylinder five 33 driving the side pressure plate 31 to reset, the hydraulic cylinder six 38 can be controlled to drive the fixed long plate 39 to move downward, and the fixed long plate 39 drives the bending rod 310 and the pressing frame 311 to move downward, and then the hydraulic cylinder five 33 can be controlled to work. At this time, the pressing frame 311 applies the force of the hydraulic cylinder five 33 to the steel structure profile two 6. By controlling the work of the hydraulic cylinder five 33, a certain force is applied to the steel structure profile two 6 to detect the quality of the welding process between the steel structure profile two 6 and the steel structure profile one 5. When the inspection is completed, the side pressure plate 31 is suspended, and the hydraulic cylinder six 38 works again to push the fixed long plate 39, the bending rod 310 and the pressing frame 311 to move upward, so that the pressing frame 311 moves to the top of the steel structure profile two 6, and the side pressure plate 31 then works to drive the side pressure plate 31 to reset.

[0050] In addition, the distance between the two hydraulic cylinders 25 can be adjusted to adapt to different steel structure profiles 5, ensuring the stability of the steel structure profile 5 being clamped and transported.

[0051] In addition, such as Figure 5 and Figure 6 As shown, the roller member includes a wheel frame 112, and the wheel frame 112 is fixedly connected to the U-shaped frame 16. The rollers 113 rotatably connected on both sides of the wheel frame 112 are in contact with the trapezoidal plate 110, reducing the resistance of the trapezoidal plate 110 to lift the roller member, and a space is left between the two rollers 113 so that the rollers 113 cannot contact the bottom plate 11, ensuring that the rotating shaft 17 completely enters the bottom plate 11 after the U-shaped frame 16 moves downward.

[0052] In addition, such as Figure 8 As shown, the pressing frame 311 is slidably connected to the upper pressing plate 36 to reduce the force applied by the pressing frame 311 to the upper pressing plate 36 and reduce the possibility of bending and deformation of the bending rod 310. In addition, multiple drag reduction shafts 312 are rotatably connected inside the pressing frame 311 to reduce the friction resistance of the pressing frame 311 moving up and down.

[0053] In addition, such as Figure 5 As shown, the bottom end of the damper 19 is fixedly connected to the bottom plate 11, and the top end of the damper 19 is fixedly connected to the U-shaped frame 16. The damper 19 limits the up and down movement of the U-shaped frame 16 to avoid the possibility of the U-shaped frame 16 being skewed.

[0054] In addition, such as Fig.10 As shown, a limiting round rod 211 is fixedly connected to the top of the clamping plate 210 , and multiple limiting round rods 211 all penetrate the clamping frame 27 . The multiple limiting round rods 211 limit the up and down movement of the clamping plate 210 , thereby increasing the working stability of the clamping plate 210 .
