Description

Technical Field

[0001] This utility model belongs to the technical field of anti-displacement structures for steel structure welding, specifically an anti-displacement structure for steel structure welding. Background Technology

[0002] In the steel structure welding process, especially in the assembly and welding of large or irregularly shaped components, ensuring that the workpiece remains accurately positioned and does not shift under the heat effect of welding is a key challenge to guarantee welding quality and dimensional accuracy. Traditional fixing methods usually use bolts, pressure plates or simple clamps.

[0003] However, these traditional fixing methods are time-consuming and laborious when adjusting the position of the clamps or tightening the bolts, and it is difficult to quickly adapt to workpieces with different welding angles, which affects production efficiency and causes the workpieces to easily slip or twist, resulting in misaligned welds and out-of-tolerance dimensions. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional fixing methods are time-consuming and laborious when adjusting the position of the clamps or tightening the bolts, and it is difficult to quickly adapt to workpieces with different welding angles. This utility model proposes an anti-displacement structure for steel structure welding.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a steel structure welding anti-deviation structure, including an electromagnetic clutch, the top of which is provided with two sets of fixing mechanisms; Both sets of fixing mechanisms include a support platform. The bottom end of the support platform is rotatably mounted on the top end of the electromagnetic clutch. An electric cylinder is fixedly mounted on the top end of the support platform. A connecting plate is fixedly mounted on the top end of the electric cylinder. A pressure cap is threaded into the inner cavity of the connecting plate. A welding table is fixedly connected to the top end of the support platform. A baffle is movably mounted on the top end of the welding table. An electric push rod is fixedly mounted on one side of the baffle. The bottom end of the electric push rod is fixedly mounted on the top end of the welding table.

[0006] Preferably, a first slider is fixedly installed at the bottom end of the electromagnetic clutch, and a first slide rail is slidably connected to the inner cavity of the first slider.

[0007] Preferably, the surface of the electromagnetic clutch is connected to a pulley via a belt drive, and a second slider is rotatably connected to the bottom end of the pulley.

[0008] Preferably, a connecting block is fixedly connected to one side of the first slider, and a lead screw is threadedly connected to the inner cavity of the connecting block.

[0009] Preferably, one end of the lead screw is rotatably connected to a fixing block, and two sets of guide rods are fixedly installed on the inner side of the fixing block.

[0010] Preferably, one end of each of the two sets of guide rods is fixedly connected to a screw hole block, the inner cavity of the screw hole block is threaded to a lead screw, and a first motor is fixedly installed at the smooth end of the lead screw.

[0011] Preferably, a second motor is fixedly installed in the inner cavity of the pulley, a second slide rail is slidably connected in the inner cavity of the second slider, and a worktable is fixedly installed at the bottom end of the second slide rail.

[0012] Preferably, the sliding mechanism includes a third slide rail, the bottom end of which is fixedly connected to the top end of the support platform, and a third slider is slidably connected to the top end of the third slide rail. A guide rail clamp is fixedly installed in the inner cavity of the third slider.

[0013] Compared with existing technologies, this utility model, by setting a fixing mechanism on the electromagnetic clutch, can achieve horizontal rotation adjustment of the workpiece during welding, which improves the adaptability and adjustment efficiency of the device to different welding positions and workpiece contours. The electric cylinder drives the threaded pressure cap to provide controllable vertical clamping force, which can resist the upward arching or separation caused by welding heat deformation. At the same time, the electric push rod drives the baffle to provide adjustable horizontal clamping force, which restricts the movement and displacement of the workpiece in the horizontal plane, forming a two-way constraint to ensure that the workpiece is stable and does not deviate during the welding process. The electric cylinder is connected to a sliding mechanism, which can move horizontally to adjust the fixing position of workpieces of different sizes. This solves the problems of traditional fixing methods, which are time-consuming and laborious when adjusting the position of the clamp or tightening the bolts, and are difficult to quickly adapt to workpieces with different welding angles.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail; This application discloses an anti-displacement structure for welding steel structures. (Refer to...) Figure 1 and Figure 2 A steel structure welding anti-deviation structure includes an electromagnetic clutch 1. The top of the electromagnetic clutch 1 is provided with two sets of fixing mechanisms 2. Each set of fixing mechanisms 2 includes a support platform 201. The bottom end of the support platform 201 is rotatably mounted on the top of the electromagnetic clutch 1. A sliding mechanism 202 is mounted on the top of the support platform 201. An electric cylinder 203 is mounted on the sliding mechanism 202. A connecting plate 204 is fixedly mounted on the top of the electric cylinder 203. A pressure cap 205 is threadedly connected to the inner cavity of the connecting plate 204. A welding table 206 is fixedly connected to the top of the support platform 201. A baffle 207 is movably mounted on the top of the welding table 206. One side of the baffle 207 is fixed... An electric actuator 208 is installed, with its bottom end fixedly mounted on the top of the welding table 206. The electromagnetic clutch 1 can drive the support table 201 to achieve horizontal rotation from 0° to 360° to adapt to different welding angle requirements. The sliding mechanism 202 is used to adjust the position of the electric cylinder 203. The electric cylinder 203 on the sliding mechanism 202 is used to drive the pressure cap 205 to press the workpiece and prevent the workpiece from moving randomly. The pressure cap 205 with threaded connection can realize the adjustability of the workpiece pressing height. The welding table 206 serves as a workpiece bearing platform, and the electric actuator 208 on it provides linear driving force to the baffle 207 to squeeze and fix the steel part, achieving lateral limit.

[0019] Reference Figure 1 and Figure 3The bottom end of the electromagnetic clutch 1 is fixedly installed with a first slider 3, and the inner cavity of the first slider 3 is slidably connected to a first slide rail 4; the electromagnetic clutch 1 is installed on the first slider 3 and can move horizontally along the first slide rail 4 with the first slider 3.

[0020] Reference Figure 1 and Figure 5 The surface of the electromagnetic clutch 1 is connected to a pulley 5 via a belt drive. The bottom end of the pulley 5 is rotatably connected to a second slider 6. The pulley 5 drives the electromagnetic clutch 1 to rotate via the belt, so that the fixed mechanism 2 can be rotated and adjusted. The second slider 6 is connected to the pulley 5, so that the pulley 5 can slide horizontally at the corresponding position with the second slider 6.

[0021] Reference Figure 1 , Figure 3 and Figure 5 A connecting block 7 is fixedly connected to one side of the first slider 3, and a lead screw 8 is threadedly connected to the inner cavity of the connecting block 7. The connecting block 7 is connected to the first slider 3, and together with the lead screw 8, a lead screw drive can be formed to drive the first slider 3 to make horizontal displacement without manual pushing, saving time and effort.

[0022] Reference Figure 1 One end of the lead screw 8 is rotatably connected to a fixing block 9, and two sets of guide rods 10 are fixedly installed on the inner side of the fixing block 9. The purpose of setting the fixing block 9 and the two sets of guide rods 10 is mainly to cooperate with the lead screw 8 to form a lead screw drive, which is well known to those skilled in the art, so it will not be described in detail here.

[0023] Reference Figure 1 and Figure 3 Two sets of guide rods 10 are fixedly connected to one end of a screw hole block 11. The inner cavity of the screw hole block 11 is threaded to the lead screw 8. The bare end of the lead screw 8 is fixedly installed with a first motor 12. The screw hole block 11 allows the lead screw 8 to rotate within it. Since one end of the lead screw 8 is rotatably connected to one side of the fixed block 9, it cannot move forward. Due to the guidance of the guide rod 10 on the connecting block 7, the first motor 12 drives the lead screw 8 to rotate, forcing the connecting block 7 to move horizontally. Subsequently, the first slider 3 connected to the connecting block 7 moves together.

[0024] Reference Figure 1 and Figure 2 The inner cavity of the pulley 5 is fixedly installed with a second motor 13, and the inner cavity of the second slider 6 is slidably connected with a second slide rail 14. The bottom end of the second slide rail 14 is fixedly installed with a worktable 15. The second motor 13 can drive the pulley 5 to rotate, thereby driving the fixed mechanism 2 on the electromagnetic clutch 1 to rotate, so that the angle adjustment can be achieved without manual intervention.

[0025] Reference Figure 2 and Figure 5The sliding mechanism 202 includes a third slide rail 2021, the bottom end of which is fixedly connected to the top end of the support platform 201. A third slider 2022 is slidably connected to the surface of the third slide rail 2021. A guide rail clamp 2023 is provided in the inner cavity of the third slider 2022. The third slide rail 2021 provides support for the horizontal movement of the third slider 2022. The guide rail clamp 2023 is used to lock the position of the third slider 2022 on the third slide rail 2021 to ensure that the electric cylinder 203 remains fixed after positioning.

[0026] Working principle: When welding steel structures, the connecting plate 204 is first moved horizontally to directly above the workpiece by manipulating the sliding mechanism 202, causing the pressure cap 205 to move horizontally. Then, the electric cylinder 203 is activated to push the connecting plate 204 and the pressure cap 205 downwards in the vertical direction, so that the bottom working surface of the pressure cap 205, after thread adjustment, tightly presses against the upper surface of the workpiece, achieving longitudinal fixation of the workpiece. At the same time, the electric actuator 208 is activated simultaneously to drive the baffle 207 to move laterally along the surface of the welding table 206, so that the baffle 207 laterally squeezes the edge of the workpiece, completing the bidirectional displacement constraint of the workpiece. During the welding process, the electromagnetic clutch 1 is energized to release its self-locking state. At this time, the fixing mechanism 2 can be manually or driven by a motor to rotate 360 ​​degrees around the support platform 201. After the angle adjustment is completed, the power supply of the electromagnetic clutch 1 is turned off to complete the self-locking. Welding can then be carried out. This design allows the workpiece on the welding table 206 to match the welding angle requirements, thereby reducing the workpiece displacement caused by welding thermal deformation. After welding is completed, the lateral pressure of the electric push rod 208, the vertical pressure of the electric cylinder 203, and the rotation lock of the electromagnetic clutch 1 are released in sequence, and each mechanism is reset.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
