Description

Technical Field

[0001] This application relates to the technical field of steel structures, and in particular to a steel structure welding auxiliary device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of components such as beams, steel columns, and steel trusses made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. In order to improve the stability of welding between components, a magnetic welding positioner has been designed.

[0003] Regarding the aforementioned technologies, the inventors believe that traditional steel structure welding processes struggle to flexibly adjust welding positions and angles. As steel structure applications expand, higher demands are placed on welding quality and efficiency. Existing welding auxiliary devices often fail to meet the needs of omnidirectional welding when dealing with complex steel structures. For example, in the construction of steel structures for large buildings, traditional devices struggle to quickly adjust welding positions, leading to low welding efficiency and delays. Furthermore, traditional devices lack stability when fixing workpieces, making them prone to displacement during welding, which affects welding quality. Therefore, to address these issues, this application provides a steel structure welding auxiliary device. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a steel structure welding auxiliary device.

[0005] This application provides a steel structure welding auxiliary device, including a base and a clamping assembly. The surface of the base is provided with a horizontal groove, and a lead screw is rotatably connected inside the horizontal groove. An adjusting block is threadedly connected to the outside of the lead screw. A processing table is fixedly connected to the top of the adjusting block. A servo motor is fixedly connected to the outside of the base. The output end of the servo motor extends into the horizontal groove and is fixedly connected to the lead screw through a coupling.

[0006] An L-shaped plate is fixedly connected to the surface of the base, and an electric telescopic rod is fixedly connected to the top of the L-shaped plate. A drive motor is mounted on the output end of the electric telescopic rod via a support, and a disc is fixedly connected to the output end of the drive motor via a coupling. A welding machine is installed on the edge of the disc.

[0007] Preferably, the clamping assembly includes a vertical groove formed on the surface of the processing table, a bidirectional screw is rotatably connected inside the vertical groove, and two sliders are symmetrically threaded to the outside of the bidirectional screw, with a clamping plate fixedly connected to the top of each of the two sliders.

[0008] Preferably, one section of the bidirectional screw extends to the outside of the base and is equipped with a rotating handle.

[0009] Preferably, support pads are installed at all four corners of the bottom of the base.

[0010] Preferably, the bottom of the processing table is in close contact with the upper surface of the base, and the bottom of the clamping plate is in close contact with the upper surface of the processing table.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By creating horizontal grooves on the base surface and installing lead screws and adjusting blocks within these grooves, the processing table can be horizontally adjusted along the lead screws. Simultaneously, the electric telescopic rod at the top of the L-shaped plate drives the drive motor and welding machine to move vertically, while the disc connected to the output end of the drive motor enables the welding machine to rotate in a circular motion. This multi-dimensional adjustment design allows the welding machine to precisely reach various welding points on the steel structure, meeting welding requirements at different angles and positions, and greatly improving the flexibility and precision of welding.

[0013] 2. The clamping assembly has vertical slots on the surface of the machining table. When the bidirectional screw inside the slot rotates, the two sliders threaded to it move relative to each other, thereby driving the clamping plate at the top to clamp the workpiece. This design can accommodate steel structure workpieces of different sizes. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 - Figure 4This application will be described in further detail.

[0020] Example 1:

[0021] A steel structure welding auxiliary device, referring to Figure 1 - Figure 4 The system includes a base 1 and a clamping assembly. The surface of the base 1 has a horizontal groove 2. A lead screw 3 is rotatably connected inside the horizontal groove 2. An adjusting block 4 is threadedly connected to the outside of the lead screw 3. A processing table 5 is fixedly connected to the top of the adjusting block 4. The bottom of the processing table 5 is tightly fitted to the upper surface of the base 1. A servo motor 17 is fixedly connected to the outside of the base 1. The output end of the servo motor 17 extends into the horizontal groove 2 and is fixedly connected to the lead screw 3 through a coupling. An L-shaped plate 6 is fixedly connected to the surface of the base 1. An electric telescopic rod 7 is fixedly connected to the top of the L-shaped plate 6. A drive motor 16 is mounted on the output end of the electric telescopic rod 7 through a support. A disc 8 is fixedly connected to the output end of the drive motor 16 through a coupling. A welding machine 9 is installed at the edge of the disc 8.

[0022] Specifically, when the servo motor 17, which is fixedly connected to the outside of the base 1, is started, the output end of the servo motor 17 drives the lead screw 3 to rotate through the coupling. According to the principle of thread transmission, the rotation of the lead screw 3 is converted into the linear movement of the adjusting block 4 in the transverse groove 2. Since the processing table 5 is fixed on the top of the adjusting block 4, the processing table 5 will also move horizontally. This design can accurately adjust the horizontal position of the steel structure workpiece placed on the processing table 5, ensuring that the welding machine 9 can be aligned with the welding points at different horizontal positions to achieve precise welding. Compared with manual adjustment, the intervention of the servo motor 17 makes the adjustment process more efficient and precise. The processing can be accurately controlled by controlling the rotation angle and speed of the servo motor 17. The moving distance and speed of platform 5, after the electric telescopic rod 7 is started, the telescopic rod will move along its own axis to extend and retract. Since the output end of the electric telescopic rod 7 is connected to the drive motor 16 through the support, and the drive motor 16 is connected to the disc 8 and the welding machine 9, the extension and retraction of the electric telescopic rod 7 will drive the drive motor 16, the disc 8 and the welding machine 9 to rise and fall synchronously in the vertical direction. In this way, the distance between the welding machine 9 and the steel structure workpiece in the vertical direction can be flexibly adjusted to meet the welding needs of different height positions. Whether welding the weld at a higher position or welding the position close to the base, it can be easily achieved. After the drive motor 16 is started, its output shaft begins to rotate in a circle. This rotation is transmitted to the disc 8 via a coupling, causing the disc 8 to move in a circular motion around its own center. The welding machine 9 is installed at the bottom edge of the disc 8, so it moves along a circular trajectory centered on the center of the disc 8 as the disc 8 rotates. This design gives the welding machine 9 the ability to perform circumferential welding operations around the steel structure workpiece, which can meet the welding requirements of different angles and greatly improve the flexibility of welding position adjustment. It can better complete some steel structure welding tasks with complex shapes or special angle requirements. In addition, it is necessary to plan the routing of the welding machine power cord so that it is arranged along the rotation trajectory of the disc, and use a fixing device to fix the cable to the disc or a nearby structure to ensure that the cable can follow the movement smoothly when the disc rotates without getting tangled.

[0023] Reference Figure 1 and Figure 3 The clamping assembly includes a vertical groove 10 formed on the surface of the processing table 5. A bidirectional screw 11 is rotatably connected inside the vertical groove 10. One section of the bidirectional screw 11 extends to the outside of the base 1 and is equipped with a rotating handle 14. Two sliders 12 are symmetrically threaded to the outside of the bidirectional screw 11. A clamping plate 13 is fixedly connected to the top of each slider 12. The bottom of the clamping plate 13 is in close contact with the upper surface of the processing table 5.

[0024] Specifically, the operator rotates the rotating handle 14 located outside the base 1, which drives the bidirectional screw 11 to rotate synchronously. The two threads of the bidirectional screw 11 have opposite directions of rotation, and the two sliders 12 are symmetrically connected to the two threads of the bidirectional screw 11 respectively. According to the principle of thread transmission, when the bidirectional screw 11 rotates, the two sliders 12 will move relative to each other along the vertical groove 10. The clamping plates 13 are fixed at the top of the two sliders 12, so the two clamping plates 13 will also move relative to each other, gradually approaching and clamping the steel structure workpiece placed on the processing table 5. This design can quickly clamp steel structure workpieces of different sizes. By rotating the rotating handle 14, the distance between the clamping plates 13 can be easily adjusted to adapt to workpieces of different specifications.

[0025] Reference Figure 2 Support pads 15 are installed at the four corners of the bottom of the base 1.

[0026] Specifically, the support pad 15 has a certain degree of elasticity and a large frictional force. When the device is placed on the working surface, the support pad 15 first adapts to the uneven working surface through elastic deformation, so that the base 1 can be placed stably. During the operation of the device, vibrations generated by welding, external pushing forces, etc., may cause the device to shift. The large frictional force between the support pad 15 and the working surface can effectively resist these external forces and prevent the device from shifting.

[0027] The implementation principle of a steel structure welding auxiliary device according to an embodiment of this application is as follows: the electric telescopic rod 7 is preferably of type LX600, the drive motor 16 is preferably of type YE2132M-4, and the servo motor 17 is preferably of type HBS57. The electric telescopic rod 7, drive motor 16, and servo motor 17 are all electrically connected to an external power supply via a switch. When the steel structure welding auxiliary device is working, the servo motor 17 is started by the switch, and its output end drives the lead screw 3 to rotate through a coupling. The threaded transmission causes the adjusting block 4 to move linearly within the transverse groove 2, thereby driving the top processing table 5 to move horizontally and precisely adjust the steel structure placed on the processing table 5. The horizontal position of the workpiece is ensured to align the welding machine 9 with different horizontal welding points. Additionally, the routing of the welding machine's power cable needs to be carefully planned, arranging it along the rotation trajectory of the disc. The cable should be secured to the disc or a nearby structure using a fixing device to ensure smooth movement without tangling as the disc rotates. Compared to manual adjustment, the servo motor 17 can more efficiently and precisely control the movement of the processing table 5 by controlling the rotation angle and speed. Simultaneously, the electric telescopic rod 7 is activated by a switch, extending and retracting axially. Since its output end is connected to the drive motor 16, it drives the connected disc 8 and welding machine 9 vertically. The direction of the lifting mechanism allows for flexible adjustment of the vertical distance between the welding machine 9 and the workpiece, meeting welding requirements at different heights. The drive motor 16 is activated by a switch, and its output shaft rotates circumferentially, transmitting the rotation to the disc 8 via a coupling. This causes the disc 8 to rotate around its own center, and the welding machine 9, mounted on the bottom edge of the disc 8, moves accordingly along a circular trajectory, satisfying welding requirements at different angles and improving the flexibility of welding position adjustment. When clamping the workpiece, the operator rotates the external rotating handle 14 of the base 1, causing the bidirectional screw 11 inside the vertical groove 10 to rotate. Because the two screws rotate in opposite directions, the two symmetrically connected sliders 12 move relative to each other along the vertical groove 10, causing the top clamping plate 13 to... Gradually approach and clamp the steel structure workpieces of different sizes placed on the processing table 5. In addition, the support pads 15 installed at the four corners of the bottom of the base 1 adapt to the uneven working surface by their own elastic deformation, so that the device is placed stably. Its large friction force effectively resists welding vibration, external pushing and other external forces, prevents the device from shifting, and provides a stable foundation for efficient and accurate welding operations. The threads on both sides of the double screw 11 are opened in opposite directions and the pitch is equal. The thread opening angle of the screw 3 and the double screw 11 is 20 degrees. The thread self-locking condition must meet the following formula calculation: self-locking condition = friction coefficient × tan (helix angle) ≥ 1.
