Description

Technical Field

[0001] This utility model belongs to the technical field of resistance spot welding, specifically relating to a double-arm C-type welding torch. Background Technology

[0002] With the increasing market competition, the demand for product diversification in the manufacturing market is becoming more and more significant. Different customers have personalized requirements for product functions, appearance and performance, which requires welding equipment to be able to adapt to various welding processes and weldments of different shapes and sizes.

[0003] Traditional C-arm welding torches employ a single-arm fixed structure, with their movement trajectory primarily revolving around a fixed pivot point. Their range of motion is limited to a relatively small space around the welding point. In actual welding operations, for complex-shaped workpieces, a single-arm C-arm welding torch struggles to reach all welding positions within its limited angle and range of motion. Furthermore, a single-arm fixed C-arm welding torch can only complete one welding point at a time, requiring mechanical movement or manual adjustment before moving to the next point. For large workpieces with numerous welding points, although the welding time for each point is short, the frequent position changes significantly increase the overall welding time, leading to low production efficiency and increased production costs and cycles.

[0004] There is an urgent need for an X-type welding gun with a wider processing range and the ability to quickly switch welding points. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a double-arm C-type welding torch to solve the problems of limited processing range and inability to quickly switch welding points in the prior art.

[0006] One embodiment of this utility model provides a double-arm C-type welding torch, comprising:

[0007] The gun body assembly integrates the drive assembly, moving assembly, and electrode assembly, and moves the electrode assembly to the corresponding processing position;

[0008] Driver components are used to drive active components;

[0009] The active component is used to adjust the processing position of the electrode assembly under the drive of the drive component;

[0010] Electrode assembly, used to complete workpiece welding;

[0011] Both the drive assembly and the movable assembly are mounted on the gun body assembly, and the electrode assembly is mounted on the movable assembly;

[0012] The electrode assembly includes a first electrode and a second electrode. The first electrode moves along the horizontal direction where the second electrode is located under the drive of the drive assembly, and the second electrode moves along the horizontal direction where the first electrode is located under the drive of the drive assembly.

[0013] It should be noted that in actual use, the working modes of driving the moving component through the driving component, and then the moving component driving the electrode component, include the following two:

[0014] First mode: The gun body assembly moves to the corresponding processing position, the drive assembly starts to work, and the drive moving assembly synchronously drives the first electrode and the second electrode to move closer to each other. When the first electrode and the second electrode contact the welding points on both sides of the processed part, they abut against the welding points.

[0015] Second mode: The gun body assembly moves to the corresponding processing position, the drive assembly starts to work, and the drive moving assembly drives the first electrode and the second electrode to move independently. When the first electrode and the second electrode come into contact with the welding points on both sides of the workpiece, they abut against the welding points respectively.

[0016] Third mode: The drive component starts working, and the drive active component synchronously moves the first electrode and the second electrode away from each other. The first electrode and the second electrode are reset to their initial positions, waiting for the gun body assembly to move, so that when the first electrode and the second electrode reach the next welding point, they can be processed again.

[0017] In this solution, the electrode assembly is positioned by the gun body assembly, and the working angle of the electrode is adjusted by the cooperation of the drive assembly and the movable assembly. On the one hand, the welding gun can quickly adapt to different processing positions and quickly switch welding points in three working modes, which increases the processing range of the welding gun and achieves the effect of rapid switching of welding points. On the other hand, the design of integrating various components by the gun body assembly and mounting the electrode assembly on the movable assembly makes it easy for technicians to quickly disassemble the relevant components and facilitate daily maintenance and replacement of parts.

[0018] In one embodiment, the movable component includes a transmission component, a connector, and a double-ended rotating component. The transmission component passes through the middle of the double-ended rotating component and is fixed to the gun body assembly. The double-ended rotating component is configured to rotate about the transmission component as the center. One end of the double-ended rotating component is connected to the drive assembly, and the other end is connected to the second electrode through the connector. The drive assembly drives the second electrode to move through the double-ended rotating component and the connector.

[0019] In one embodiment, the first electrode includes a first electrode rod and a first electrode cap, the end of the first electrode rod is connected to the connector, and the second electrode includes an electrode arm, the end of the electrode arm is provided with a second electrode rod, and the end of the second electrode rod is provided with a second electrode cap.

[0020] In one embodiment, the drive assembly is connected to one end of the double-ended rotating member, and the electrode arm is connected to the other end of the double-ended rotating member via the connector.

[0021] It should be noted that in actual use, the double-ended rotating component, driven by the drive assembly, drives the rotating connector to move, and the connector drives the electrode assembly to move synchronously. Taking the first mode as an example, when the drive assembly pushes one end of the double-ended rotating component, the other end of the double-ended rotating component is driven in the opposite direction. At this time, the electrode arm is driven to move by the other end, thereby realizing the driving effect of the transmission component on the connector. The connector connected to the first electrode rod is directly pushed by the drive assembly, completing the mutual approach of the first electrode cap and the second electrode cap. In the first mode, the electrode rods on the two electrodes approach each other, specifically, the electrode caps of the two electrode rods approach each other, until the electrode caps of the two electrode rods abut against the two welding points on the top surface and the ground of the workpiece. The second and third modes are similar.

[0022] In this solution, through the cooperation of the transmission component and the connecting component in the moving component, and the cooperation of the electrode arm, electrode rod and electrode cap in the electrode assembly, the electrode arm can drive the second electrode rod and the second electrode cap to move synchronously under the drive of the double-ended rotating component and the connecting component, so as to control the first electrode cap and the second electrode cap to move closer to each other, further away from each other or move independently, thereby realizing the adjustment of the processing range of the electrode cap.

[0023] In one embodiment, the gun body assembly includes a side housing and an end housing, with both the drive assembly and the movable assembly mounted on the side housing.

[0024] In one embodiment, both the side housing and the end housing are provided with mounting members. The side housing is connected to the drive assembly through the mounting members, and the end housing is connected to the side housing through the mounting members.

[0025] In this solution, by setting mounting parts on the side housing and end housing, and connecting the drive assembly and moving assembly with the mounting parts, the installation of each assembly can be made more stable, and the installation and disassembly of each assembly can be facilitated, which greatly improves the assembly and maintenance efficiency of the welding torch.

[0026] In one embodiment, an electrode mounting groove is provided on the end housing, and all electrode arms are mounted in the electrode mounting groove.

[0027] In this solution, by opening an electrode mounting groove on the end housing and installing the electrode arm in the electrode mounting groove, the electrode arm can be limited and fixed, ensuring the installation stability of the electrode assembly and allowing the electrode assembly to maintain the correct position and posture during operation.

[0028] In one embodiment, the side housing is provided with extended heat dissipation holes.

[0029] In this solution, by opening extended heat dissipation holes on the side housing, the heat dissipation area of ​​the side housing can be increased, the heat dissipation efficiency can be improved, the heat generated by the welding torch during operation can be dissipated in time, the performance degradation caused by overheating can be prevented, and the stable operation of the welding torch can be ensured.

[0030] In one embodiment, the electrode assembly is externally connected to a cooling water pipe.

[0031] In this solution, by connecting the cooling water pipe to the electrode assembly, the electrode assembly can be cooled in a targeted manner, removing the large amount of heat generated during the welding process, thus preventing the electrode assembly from being damaged by high temperature and extending its service life.

[0032] In one embodiment, the drive component is externally connected to a power supply line, an adaptive feedback line, and an encoder line.

[0033] In this solution, by connecting the power supply line, adaptive feedback line, and encoder line to the drive component, the power supply line can provide a continuous and stable power supply to the drive component, ensuring its normal operation; the adaptive feedback line can provide real-time feedback on the welding torch's working status, facilitating the adjustment of the welding torch's working parameters; and the encoder line can precisely control the operation of the drive component, improving the accuracy and stability of the drive component's operation.

Taking the first mode as an example, when the driving component 2 pushes one end of the double-ended rotating part 311, the other end of the double-ended rotating part 311 is driven in the opposite direction. At this time, the electrode arm 421 is driven to move by the other end, thereby realizing the driving effect of the transmission component 31 on the connecting part 32.
