Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and specifically provides a steel structure installation welding auxiliary positioning device. Background Art

[0002] During the installation of steel structures, welding is the main method for connecting steel structure components. However, since steel structure components are usually large in volume, heavy in weight, and diverse in shape, accurately positioning and fixing these components during the welding process has become a technical problem. To ensure the welding quality, special fixtures and support structures are required to stabilize the components and prevent deformation during welding. In addition, the handling and positioning of large components require heavy equipment such as cranes and mobile platforms, which increases the complexity and cost of construction. To improve the welding efficiency and quality, automated welding technologies such as robotic welding systems are often used in modern construction to reduce human errors and improve production efficiency. Nevertheless, for complex or special-shaped steel structure components, experienced welders are still required to perform manual welding to ensure the quality of the welded joints and the overall performance of the structure.

[0003] The defects of existing steel structure installation welding auxiliary positioning devices are as follows:

[0004] 1. Some existing steel structure installation welding auxiliary positioning devices are insufficient in terms of accuracy and stability. Due to errors in the design or manufacturing process, the device has deviations during positioning, affecting the accuracy and consistency of welding. At the same time, during long-term use, due to wear and aging, etc., the stability gradually decreases, making it difficult to guarantee the welding quality.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] Example 1: As Figures 1-7As shown in the figure, an embodiment provided by the present invention is: a steel structure installation and welding auxiliary positioning device, including a welding machine case 3, an insulating support assembly 4, a horizontal adjustment assembly 5, a main positioning assembly 7, a welding point adjustment structure 8, a welded part fixing assembly 9, and a welding structure 10; an insulating support assembly 4 is installed at the bottom of the welding machine case 3.

This fine adjustment ability further enhances the flexibility and accuracy of welding. A welding structure 10 is installed on one side of the welding machine case 3. The installation of the welding structure 10 is the key component for performing welding operations. By precisely controlling the welding parameters and welding path, it ensures a high-quality welding effect; through the integrated and collaborative action of each component, the functionality and practicality of the steel structure installation and welding auxiliary positioning device are significantly improved, realizing the optimization and upgrading of the overall performance.

[0034] Example 2: As Figure 1 shown, an auxiliary positioning device for steel structure installation and welding proposed by the present invention, compared with Example 1, this embodiment further includes: a PLC controller 31, a leakage protector 32 and a data transmission slot 33 are installed from right to left in the rectangular groove on the lower side of the front surface of the welding machine case 3. The PLC controller 31 serves as the intelligent core of the entire device, responsible for receiving and processing data from various sensors, as well as executing preset welding programs. With its powerful computing ability, the PLC controller 31 can adjust welding parameters in real time to ensure a stable and efficient welding process; the leakage protector 32 acts as a safety guard. Once it detects a possible leakage situation during the welding process, it will immediately cut off the power supply, effectively preventing electric shock accidents and ensuring the safety of operators; the design of the data transmission slot 33 enables the device to perform data transmission with external devices, facilitating the recording and analysis of welding data and further optimizing the welding process. The reasonable layout of these electrical components not only improves the overall performance of the device but also reflects the dual attention to safety and efficiency.

[0035] In this embodiment, as Figure 1 shown, a fixed bottom plate 41 is provided on the insulating support assembly 4. The fixed bottom plate 41 is made of a high-strength insulating material and has excellent load-bearing capacity and electrical insulation performance. It is firmly installed on the insulating support assembly 4, providing a stable and safe operation platform for subsequent welding operations. An insulating backing plate 42 is fixed to the lower surface of the fixed bottom plate 41. The setting of the insulating backing plate 42 further improves the safety of the device. It effectively isolates the current and prevents the electric sparks that may be generated during the welding process from causing harm to operators or the surrounding environment, reflecting the careful consideration of safety details. A triangular support member 43 is installed on the upper surface of the fixed bottom plate 41. The design of the triangular support member 43 enhances the structural stability of the insulating support assembly 4, ensuring that the steel structure can be firmly supported during the welding process and preventing positioning deviation caused by vibration or external interference.

The detachable mounting member 53 provides flexibility, and different specifications or types of mounting members can be replaced according to the actual welding operation needs to adapt to the diverse steel structure installation requirements. The rotating adjustment screw 52 is located inside the adjustment chute 54, and the adjustment chute 54 is opened on the upper surface of the positioning workbench 6. The rotating adjustment screw 52 is matched with the adjustment chute 54 by means of threaded connection, so that the rotating disk 51 can drive the detachable mounting member 53 to make precise lateral movement on the positioning workbench 6 to meet the positioning requirements of steel structures of different sizes; and the setting of the adjustment chute 54 clearly defines the movement range of the lateral adjustment assembly 5 on the positioning workbench 6, which not only ensures the accuracy of the adjustment, but also avoids the problems of damage to the positioning device or inaccurate positioning caused by excessive movement.

[0037] In this embodiment, as Figure 4 shown, a rectangular fixing plate 71 is provided on the main positioning assembly 7. A rotating motor 72 and a vertical support plate 77 are installed on the upper surface of the rectangular fixing plate 71. The rectangular fixing plate 71 provides a stable and solid base for installing and supporting the rotating motor 72 and the vertical support plate 77. This design ensures the structural stability and operation reliability of the equipment. A main driving wheel 73 is installed on the output end of the rotating motor 72. The main driving wheel 73 is connected to the driven driving wheel 74 through a transmission belt 75. The driven driving wheel 74 is fixedly connected to one end of the bearing seat 76, and the bearing seat 76 is installed on the vertical support plate 77. When the rotating motor 72 starts, driven by the output end, the main driving wheel 73 starts to rotate, and then drives the driven driving wheel 74 to rotate through the transmission of the transmission belt 75; and the rotation of the driven driving wheel 74, due to its fixed connection relationship with the bearing seat 76, will drive the bearing seat 76 and the related components installed on the bearing seat 76 to perform rotational motion; at the same time, the vertical support plate 77, as a support structure, ensures the stable installation and operation of the bearing seat 76 and the driven driving wheel 74, and also provides the necessary supporting force for the entire main positioning assembly 7. Such a design not only realizes the angle adjustment of the steel structure during the welding process, but also greatly improves the accuracy of the adjustment and the convenience of operation by means of motor drive.

[0038] In this embodiment, as Figure 4As shown, a speed control switch 78 is nested and installed on the front surface of the vertical support plate 77. The setting of the speed control switch 78 provides users with a means of precisely regulating the rotation speed. Users can flexibly adjust the rotation speed according to the actual welding requirements and the size of the steel structure to achieve the best welding effect. The other end of the bearing seat 76 is fixedly connected to one end of the main member limiting cylinder 710. The design of the main member limiting cylinder 710 aims to ensure the stability and accuracy of the steel structure during installation. Its fixed connection with the other end of the bearing seat 76 forms a stable support structure, effectively preventing the steel structure from shifting or shaking during welding. A tightening fixing rod 79 is installed on the main member limiting cylinder 710, and an arc-shaped clamping plate 711 is installed at the bottom of the tightening fixing rod 79. The combination of the tightening fixing rod 79 and the arc-shaped clamping plate 711 further enhances the fixing effect of the steel structure. Users can tighten the tightening fixing rod 79 to make the arc-shaped clamping plate 711 tightly fit on the steel structure, thereby achieving a firm clamping of the steel structure. Such a design not only improves the welding accuracy but also ensures the safety of the welding process.

[0039] In this embodiment, as Figure 5 and Figure 7 shown, a horizontal adjustment track 81 is provided on the solder joint adjustment structure 8. The vertical adjustment track 83 is installed through the horizontal adjustment block 82. A warning light 84 is installed at the top of the vertical adjustment track 83. The installation of the warning light 84 can provide a clear visual indication during welding, ensuring the safety of the operator and avoiding accidental injuries caused by misoperation. Such a design not only improves the flexibility and efficiency of welding but also further enhances the safety of the welding process. The vertical adjustment track 83 is installed with a welding torch mounting plate 86 through the vertical adjustment block 85, and the welding torch mounting plate 86 is used to fix the welding torch 104 to ensure the stability and accuracy of the welding torch 104 during welding. Users can move left and right on the horizontal adjustment track 81 through the horizontal adjustment block 82 according to the requirements of the welding position to adjust the horizontal position of the welding torch 104. At the same time, the vertical adjustment block 85 allows users to move up and down on the vertical adjustment track 83 to further fine-tune the vertical position of the welding torch 104. Such a design enables the welding torch 104 to flexibly adapt to the welding requirements of different positions and angles, greatly improving the flexibility and efficiency of welding.

[0040] In this embodiment, as Figure 6As shown, a rotating motor 91 is provided on the welding part fixing assembly 9. A rotating shaft rod 92 is installed at the output end of the rotating motor 91, and a clamping and fixing support plate 93 is installed at the top of the rotating shaft rod 92. Driven by the rotating motor 91, the rotating shaft rod 92 can drive the clamping and fixing support plate 93 and the welding part to rotate, so as to facilitate the user to weld different parts of the welding part. Such a design not only improves the flexibility of welding, but also greatly saves the manual adjustment time during the welding process, improving the overall work efficiency. On both sides of the upper surface of the clamping and fixing support plate 93, a first clamping assembly 94 and a second clamping assembly 95 are respectively installed. The design of the first clamping assembly 94 and the second clamping assembly 95 enables the welding part to be firmly clamped on the clamping and fixing support plate 93. The materials of the clamping and fixing support plate 93, the first clamping assembly 94 and the second clamping assembly 95 are selected as high-strength wear-resistant materials, ensuring that they can still maintain sufficient strength and stability during long-term use, providing a strong guarantee for high-quality welding operations, and also ensuring the stability and durability under long-term use.

[0041] In this embodiment, as Figure 6 shown, a support rod 951 is provided on the second clamping assembly 95. A transfer box 952 is installed at the top of the support rod 951. An active adjustment screw 953 is installed on one side of the transfer box 952. The combination of the support rod 951 and the transfer box 952 not only stabilizes the overall structure, but also provides a solid support for the active adjustment screw 953, ensuring the continuity and stability of the clamping force during the welding process. One end of the active adjustment screw 953 is installed with a detachable mounting plate 955. One end of the detachable mounting plate 955 is fixedly connected with an arc-shaped fixed anti-slip plate 956. A limit fixing screw 954 is installed on the top of the transfer box 952. The design of the limit fixing screw 954 can effectively fix and adjust the position of the detachable mounting plate 955, ensuring that the arc-shaped fixed anti-slip plate 956 can closely fit the welding part, further enhancing the stability and reliability of clamping. Moreover, the rotation of the active adjustment screw 953 can push the detachable mounting plate 955 and the arc-shaped fixed anti-slip plate 956 to move along the support rod 951. In this way, the user can adjust the position of the arc-shaped fixed anti-slip plate 956 according to the size and shape of the welding part, ensuring that the welding part can be clamped tightly and stably. The design of the detachable mounting plate 955 not only facilitates the installation and disassembly of the arc-shaped fixed anti-slip plate 956, but also facilitates subsequent maintenance and replacement, extending the service life of the device. At the same time, the surface of the arc-shaped fixed anti-slip plate 956 is provided with anti-slip lines, increasing the friction force with the welding part, preventing the welding part from sliding during the welding process, and ensuring the accuracy and quality of welding.

[0042] In this embodiment, as Figure 7As shown, a transfer connector 101 is provided on one side of the welding structure 10. The transfer connector 101 is installed on one side of the welding machine case 3. The transfer connector 101 serves as a bridge between the welding structure 10 and the welding machine case 3, not only achieving a stable connection of the structure, but also facilitating the transmission of cables and signals, ensuring the smooth progress of the welding process. The other end of the transfer connector 101 is connected to the cable conduit 103. An ammeter 102 is installed on the cable conduit 103. The setting of the ammeter 102 can monitor the current change during the welding process in real time, ensuring the stability and safety of the welding operation. When the current is abnormal, the ammeter 102 can quickly issue an alarm to remind the operator to adjust in time, effectively avoiding welding quality problems caused by too large or too small current. The cable in the cable conduit 103 is fixedly connected to the welding torch 104. The design of the cable conduit 103 not only protects the cable from external interference and damage, but also ensures the neat arrangement and orderly management of the cable, reducing the entanglement and disorder of the cable and improving the work efficiency. The fixed connection between the cable and the welding torch 104 enables the welding torch 104 to stably receive current and signals during the welding process, ensuring the accuracy and consistency of the welding. This fixed connection method also facilitates the operation and control of the operator, reducing welding interruptions and mistakes caused by cable loosening or detachment, and further improving the welding efficiency and quality.
