Description

Technical Field

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

[0002] With increasingly fierce market competition, the manufacturing market is demanding greater product diversification. Different customers have personalized requirements for product functionality, appearance, and performance, which necessitates welding equipment that can adapt to various welding processes and workpieces of different shapes and sizes. The traditional X-type welding torch's single operating mode is only suitable for welding tasks of specific shapes and positions, making it difficult to flexibly adjust to complex and varied workpiece structures and welding process requirements.

[0003] Traditional X-type welding torches employ a single-arm fixed structure. In actual welding operations, for complex-shaped workpieces, such as components with multi-layered structures, internal cavities, and irregular contours, the single-arm fixed X-type welding torch struggles to reach all welding positions within its limited movement angle and range. Furthermore, during welding operations, the single-arm fixed X-type welding torch can only complete the welding of one weld point at a time. It then requires mechanical movement or manual adjustment of the position before the next weld point can be welded. For large workpieces, which have numerous welding points, although the welding time for each weld point is short, the frequent position switching significantly increases the overall welding time, leading to low production efficiency and increased production costs and production cycles.

[0004] There is an urgent need for an X-type welding gun with multiple processing angles and ranges, capable of quickly switching welding points. Utility Model Content

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

[0006] One embodiment of this utility model provides a double-arm X-shaped 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 movable component is used to adjust the working angle 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 portion and a second electrode portion, which move closer to or further away from each other 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 part and the second electrode part to move closer to each other. When the first electrode part and the second electrode part contact the welding points on the top and bottom surfaces of the workpiece, they abut against the welding points.

[0015] Second 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 return to their initial positions and wait 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.

[0016] 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 two working modes, increasing the processing angle and processing range of the welding gun and achieving the effect of quickly switching welding points. On the other hand, the design of integrating various components through 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.

[0017] In one embodiment, the movable component includes a rotating component and a transmission component. The transmission component connects the driving component and the electrode component. The first electrode portion and the second electrode portion are connected through the rotating component, so that under the action of the driving component, the transmission component drives the electrode component to rotate around the rotating component.

[0018] Specifically, the rotating component can be a pin. In actual operation, the drive component can drive the first electrode or the second electrode to rotate around the pin according to the processing requirements through the transmission component.

[0019] In one embodiment, both the first electrode portion and the second electrode portion include an electrode arm, the end of each electrode arm is provided with an electrode rod, and the top of each electrode rod is provided with an electrode cap.

[0020] In one embodiment, the active component includes a first connecting plate and a second connecting plate, and the electrode arms are connected between the first connecting plate and the second connecting plate and extend from between the first connecting plate and the second connecting plate.

[0021] It should be noted that in actual use, the transmission component drives the rotating component to rotate under the drive component, and the rotating component drives the electrode assembly to rotate synchronously. That is, in the first mode, the electrode rods on the two electrode arms move closer to each other, specifically the electrode caps of the two electrode rods move closer to each other until the electrode caps of the two electrode rods abut against the two welding points on the top surface of the workpiece and the ground. The second mode is the same.

[0022] In this solution, through the cooperation of the rotating and transmission components in the movable assembly, and the cooperation of the electrode arm, electrode rod, and electrode cap in the electrode assembly, the electrode arm can be rotatably connected between the first and second connecting plates in the movable assembly. The rotation of the electrode arm is controlled by the rotating component, so that the electrode rod drives the electrode cap to move synchronously, thereby realizing the adjustment of the processing angle of the electrode cap.

[0023] In one embodiment, the gun body assembly includes a side housing and an end housing, the drive assembly is mounted on the side housing, and the movable assembly is mounted within the space enclosed by the side housing and the end 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] It should be noted that the drive components may specifically include a servo motor and a transformer. The servo motor has external power lines and encoder lines, and the transformer has external power lines and adaptive feedback lines.

[0034] 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.

[0051] It should be noted that, in actual use, the working modes in which the driving component 2 drives the moving component 3, and the moving component 3 in turn drives the electrode component 4, include the following two:

[0052] First mode: Gun body assembly 1 moves to the corresponding processing position, drive assembly 2 starts working, drive moving assembly 3 synchronously drives the first electrode part 41 and the second electrode part 42 to move closer to each other, and the first electrode part 41 and the second electrode part 42 abut against the weld points when they contact the weld points on the top and bottom surfaces of the workpiece.
