Description

Technical Field

[0001] The invention relates to the technical field of welding platforms, in particular to a tooling platform for preventing deformation of steel structure welding. Background Art

[0002] A tooling platform is one of the basic facilities for welding operations. It is mainly used to fix and support the workpiece to be welded, ensuring stability and precision during the welding process. The tooling platform can provide stable support, ensuring that the workpiece does not move or deform during the welding process, thereby ensuring welding quality. High-quality tooling platforms are precision-machined and can provide accurate positioning and clamping functions, reducing errors during the welding process. Through the reasonable design and use of tooling platforms, welding operations can be simplified and work efficiency can be improved. It can be used for welding steel structures. Common steel structures such as frames and trusses are mostly made by welding I-section steel.

[0003] A common problem during welding of common steel components is that they are prone to deformation after welding. Preheating can be used to reduce the temperature difference during welding, thereby avoiding deformation. However, the existing welding table requires the steel components to be fixed with a clamp and does not have the technical effect of preheating, so it cannot effectively overcome the deformation problem. Summary of the Invention

[0006] Furthermore, first electric push rods are fixed to both ends of the welding tooling platform close to the outside of the first limiting frame, and a connecting frame is fixed to the extended end of the first electric push rod, and the connecting frame is fixedly connected to the bottom of the first limiting frame.

[0007] Furthermore, the preheating assembly also includes a vertical frame, and the welding tooling platform is fixed with vertical frames on both sides of the upper frame and the lower frame. Moving blocks are fixed on the outer surfaces of both sides of the upper frame and the lower frame, and the moving blocks are slidably connected to the vertical frames.

[0008] Furthermore, a bidirectional screw is rotatably installed inside the vertical frame through a bearing and a drive motor, and the moving blocks of the upper frame and the lower frame are respectively threadedly sleeved on the two end surfaces of the bidirectional screw.

[0009] Furthermore, a sliding rod is fixed to the outside of the moving block of the upper frame, and sliding sleeves are slidably connected to the two ends of the sliding rod. The bottom of the sliding sleeve is rotatably connected to a connecting rod through a rotating shaft, and the other end of the connecting rod is rotatably connected to the second limit frame on both sides of the welding tooling platform through the rotating shaft.

[0010] Furthermore, second electric push rods are fixed on both sides of the moving block, and the extended ends of the second electric push rods are in compression contact with the sliding sleeve.

[0011] Furthermore, the limiting assembly also includes an upper side plate, two upper side plates are symmetrically slidably installed on the surface of the upper plate, and two lower side plates are symmetrically slidably installed on the surface of the lower plate, and extrusion plates are fixed on the inner surfaces of the upper and lower side plates, and the extrusion plates, upper side plates and lower side plates are respectively extruded and contacted with different positions of the I-beam.

[0012] Furthermore, both sides of the upper plate and the lower plate are provided with sliding grooves, and both sides of the upper end side plate and the lower end side plate slide along the sliding grooves. A first spring is fixed inside the sliding groove in the second limit frame, and the first spring is fixedly connected to the upper end side plate.

[0013] Furthermore, a spring telescopic rod is fixed on the top of the second limit frame, and the bottom of the spring telescopic rod is fixedly connected to the upper plate. An adjusting screw is threadedly inserted into the top of the first limit frame, and the bottom of the adjusting screw is rotatably connected to the upper plate through a bearing.

[0014] Furthermore, two inclined guide plates are symmetrically fixed to the top of the upper plate of the first limit frame, and inclined plates are fixed to the outer sides of the two upper side plates and the lower side plate of the first limit frame. The top of the upper plate of the second limit frame is rotatably connected to a sleeve frame through a rotating shaft, and the sleeve frame is slidably sleeved on the guide plate. Sliding frames are fixed to the outer sides of the upper side plates and the lower side plates of the second limit frame, and the sliding frames are slidably connected to the inclined surfaces of the inclined plates.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention adjusts the positions of the upper plate, the lower plate, the upper side plate, the lower side plate and the extrusion plate to squeeze and contact the top, bottom and side of the I-beam, thereby ensuring the stability of the welding process and ensuring that two groups of I-beams can be neatly butt-jointed.

[0017] 2. In the present invention, the side plates in the second limit frame are also adjusted synchronously through the connection of the inclined plate, and the height of the upper plate of the first limit frame is adjusted by rotating the adjusting screw. The upper plate in the second limit frame is also moved and adjusted through the connection of the guide plate. In this process, because the sliding frame slides along the inclined surface of the inclined plate, the sleeve frame slides along the surface of the guide plate, and the upper plate and side plates of the first limit frame are squeezed and contacted with the surface of the I-beam. When the second limit frame approaches the first limit frame, the inclined surfaces of the guide plate and the inclined plate will make the upper plate and side plates in the second limit frame move away from the surface of the I-beam. At this time, the second limit frame does not clamp the I-beam. When the second limit frame moves away from the first limit frame, the inclined surface of the inclined plate and the guide plate will drive the upper plate and side plates to be squeezed and contacted with the surface of the I-beam again.

[0018] 3. After preheating is completed, the present invention drives the bidirectional screw to rotate by the motor, and the moving block cooperates with the thread of the screw to slide along the vertical frame to separate the upper frame and the lower frame. When the upper frame moves upward, the position of the sliding sleeve is limited by the second electric push rod, so that the sliding rod moves upward and the connecting rod can only pull the second limit frame to move away from the first limit frame. After the second limit frame moves to the vicinity of the welding end of the I-beam, the extended end of the second electric push rod is retracted, and the I-beam is pushed to move through the first limit frame at the rear end. The second limit frame can move synchronously, and the connecting rod slides along the surface of the sliding rod through the sliding sleeve to complete the docking of the two groups of I-beams.

[0019] 4. The present invention connects the first limit frame and the first electric push rod through a connecting frame, thereby facilitating the subsequent pushing of the first limit frame and the I-beam to move together to complete the docking work.

[0020] 5. Compared with the prior art, the present invention allows the welding end of the I-beam to be inserted into the preheating assembly for preheating through the guidance of the limit assembly. After the preheating is completed, the limit assembly clamps and aligns the I-beam, saving the intermediate disassembly and installation steps, improving welding efficiency, and avoiding deformation of the welding part.

When using the device, the two sections of I-beam 2 are respectively installed in the two groups of limit assemblies 3, and the welding part is inserted into the preheating assembly 4 for preheating. After reaching the preheating temperature, the upper frame 41 and the lower frame 44 of the preheating assembly 4 are separated, and the second limit frame 32 of the limit assembly 3 is moved to the vicinity of the welding part and clamped and fixed. The limit assembly 3 leads the I-beam 2 to move and dock neatly, and welding is performed along the docking part.

[0032] In this embodiment, the welding tooling platform 1 is fixed with a first electric push rod 12 at both ends close to the outside of the first limit frame 31, and a connecting frame 13 is fixed to the extended end of the first electric push rod 12. The connecting frame 13 is fixedly connected to the bottom of the first limit frame 31. The first limit frame 31 and the first electric push rod 12 are connected by the connecting frame 13, thereby facilitating the subsequent pushing of the first limit frame 31 and the I-beam 2 to move together to complete the docking work.

[0033] In this embodiment, the preheating assembly 4 also includes a vertical frame 42, and the welding tooling platform 1 is located on both sides of the upper frame 41 and the lower frame 44, and the vertical frame 42 is fixed to the outer surface of both sides of the upper frame 41 and the lower frame 44.

The bottom of the slide sleeve 48 is rotatably connected to a connecting rod 49 through a rotating shaft, and the other end of the connecting rod 49 is rotatably connected to the second limit frame 32 on both sides of the welding tooling platform 1 through a rotating shaft. A second electric push rod 410 is fixed to both sides of the moving block 46, and the extended end of the second electric push rod 410 is squeezed and contacted with the slide sleeve 48. The I-beam 2 is inserted into the first limit frame 31 and the second limit frame. Inside the frame 32, the welding end of the I-beam 2 is inserted into the combined upper frame 41 and lower frame 44, and the surface of the welding end of the I-beam 2 is preheated through the heating hole 45, that is, the existing flamethrower structure. Because the connecting rod 49 is connected to the moving block 46, the second limit frame 32 is pushed away from the preheating assembly 4. After the preheating is completed, the motor drives the bidirectional screw 43 to rotate, and the moving block 46 cooperates with the thread of the screw to slide along the vertical frame 42, separating the upper frame 41 and the lower frame 44. When the upper frame 41 moves upward, The position of the sliding sleeve 48 is limited by the second electric push rod 410, so that the sliding rod 47 moves upward and the connecting rod 49 can only pull the second limit frame 32 away from the first limit frame 31. After the second limit frame 32 moves to the vicinity of the welding end of the I-beam 2, the extended end of the second electric push rod 410 is retracted, and the I-beam 2 is pushed to move through the rear end first limit frame 31. The second limit frame 32 can move synchronously, and the connecting rod 49 slides along the surface of the sliding rod 47 through the sliding sleeve 48 to complete the docking of the two groups of I-beams 2.

[0034] In this embodiment, the limit assembly 3 also includes an upper side plate 35, two upper side plates 35 are symmetrically slidably installed on the surface of the upper plate 33, and two lower side plates 36 are symmetrically slidably installed on the surface of the lower plate 34, and an extrusion plate 37 is fixed on the inner surface of the upper side plate 35 and the lower side plate 36, and the extrusion plate 37, the upper side plate 35 and the lower side plate 36 are respectively in extrusion contact with different positions of the I-beam 2, and a sliding groove 39 is provided on both sides of the upper plate 33 and the lower plate 34, and the upper side plate 35 and the lower side plate 36 slide along the sliding groove 39, and a first spring 310 is fixed inside the sliding groove 39 in the second limit frame 32, and the first spring 310 is fixedly connected to the upper side plate 35, and the top of the second limit frame 32 is fixed There is a spring telescopic rod 311, and the bottom of the spring telescopic rod 311 is fixedly connected to the upper plate 33, the top of the first limit frame 31 is threadedly inserted with an adjusting screw 38, and the bottom of the adjusting screw 38 is rotatably connected to the upper plate 33 through a bearing, two inclined guide plates 312 are symmetrically fixed to the top of the upper plate 33 of the first limit frame 31, and the outer sides of the two upper side plates 35 and the lower side plates 36 of the first limit frame 31 are fixed with inclined plates 313, the top of the upper plate 33 of the second limit frame 32 is rotatably connected with a sleeve frame 315 through a rotating shaft, and the sleeve frame 315 is slidably sleeved on the guide plate 312, the outer sides of the upper side plates 35 and the lower side plates 36 of the second limit frame 32 are fixed with a sliding frame 314, and the sliding frame 314 slides with the inclined surface of the inclined plate 313 The first limiting frame 31 and the second limiting frame 32 have basically the same internal structure, both of which have an upper plate 33 and a lower plate 34, two upper side plates 35 and two lower side plates 36 and an extrusion plate 37. By adjusting the positions of the upper plate 33, the lower plate 34, the upper side plates 35, the lower side plates 36 and the extrusion plate 37, the top, bottom and side surfaces of the I-beam 2 are squeezed and contacted, thereby ensuring the stability of the welding process and the neat docking of the two groups of I-beams 2. The adjustment of the upper side plates 35 and the lower side plates 36 is to slide along the slide groove 39, and the adjustment of the upper plate 33 moves along the inside of the first limiting frame 31 and the second limiting frame 32, and is adjusted to a suitable clamping position according to the size of the I-beam 2. The upper side plates 35 and the lower side plates 36 in the first limiting frame 31 are When the second limit frame 32 is close to the first limit frame 31, the upper plate 33 and the side plates of the second limit frame 32 are moved away from the surface of the I-beam 2 because the sliding frame 314 slides along the inclined surface of the inclined plate 313 and the sleeve frame 315 slides along the surface of the guide plate 312.At this time, the second limiting frame 32 no longer clamps the I-beam 2. When the second limiting frame 32 moves away from the first limiting frame 31, the inclined surface of the inclined plate 313 and the guide plate 312 drive the upper plate 33 and the side plate to re-enter the surface of the I-beam 2. The cooperation between the guide plate 312 and the inclined plate 313, the sleeve frame 315 and the sliding frame 314 is a common inclined sliding structure.

[0035] When using the device, the two sections of I-beams 2 are respectively installed inside the two groups of limit assemblies 3, and the top, bottom and side surfaces of the I-beam 2 are squeezed and contacted by adjusting the positions of the upper plate 33, the lower plate 34, the upper side plate 35, the lower side plate 36 and the extrusion plate 37, thereby ensuring the stability of the welding process and the neat docking of the two groups of I-beams 2. The adjustment of the upper side plate 35 and the lower side plate 36 is to slide along the slide groove 39, and the adjustment of the upper plate 33 is to move inside the first limit frame 31 and the second limit frame 32, and to adjust to a suitable clamping position according to the size of the I-beam 2. After the adjustment is completed, the upper side plate 35 and the lower side plate 36 in the first limit frame 31 are fixed in place by bolts. The top plate 33 of the second limiting frame 32 is also moved and adjusted by rotating the adjusting screw 38 through the connection of the guide plate 312. In this process, the sliding frame 314 slides along the inclined surface of the inclined plate 313, and the sleeve frame 315 slides along the surface of the guide plate 312, pressing the top plate 33 and the side plates of the first limiting frame 31 to contact the surface of the I-beam 2. When the second limiting frame 32 is close to the first limiting frame 31, the inclined surfaces of the guide plate 312 and the inclined plate 313 will cause the top plate 33 and the side plates in the second limiting frame 32 to move away from the I-beam 2. The upper plate 33 and the side plate 31 are pressed against the upper frame 315 and the lower frame 316, and the upper plate 33 is pressed against the lower frame 317. The rod 43 rotates, and the moving block 46 cooperates with the thread of the screw to slide along the vertical frame 42, separating the upper frame 41 and the lower frame 44. When the upper frame 41 moves upward, the position of the sliding sleeve 48 is limited by the second electric push rod 410, so that the sliding rod 47 moves upward and the connecting rod 49 can only pull the second limit frame 32 away from the first limit frame 31. After the second limit frame 32 moves to the vicinity of the welding end of the I-beam 2, the extended end of the second electric push rod 410 is retracted, and the I-beam 2 is pushed to move through the rear end first limit frame 31. The second limit frame 32 can move synchronously, and the connecting rod 49 slides along the surface of the sliding rod 47 through the sliding sleeve 48 to complete the docking of the two groups of I-beams 2, and welding is performed along the docking position.
