[0015] In particular, along the extension direction of the support arm, the hinge point between the third link and the support arm is located between the hinge point between the first link and the support arm and the welding fixture body.

[0016] In one feasible implementation, the first drive assembly further includes a first reduction mechanism connected between the first drive member and the first connecting rod; and / or

[0017] The second drive assembly also includes a second reduction mechanism, which is connected between the second drive member and the second link.

[0018] In one feasible implementation, both the first deceleration structure and the second deceleration mechanism are gear mechanisms.

[0019] In one feasible embodiment, the pipe welding apparatus further includes:

[0020] The base assembly, the first drive assembly, and the second drive assembly are all disposed on the base assembly;

[0021] A motion component, disposed on the base assembly, is used to drive the base assembly to move circumferentially along the pipe to be processed.

[0022] In one feasible implementation, the base assembly forms an installation space, at least a portion of the first drive assembly and at least a portion of the second drive assembly are disposed within the installation space, and the welding fixture assembly is located outside the installation space.

[0023] In one feasible implementation, the motion component includes:

[0024] Guide rails are used to arrange along the circumference of the pipe to be processed;

[0025] Guide wheels are movably mounted on guide rails;

[0026] The third drive component is located on the base assembly, and the guide wheel is connected to the third drive component. The third drive component is used to drive the guide wheel to move along the guide rail.

[0027] In one feasible implementation, the guide rail includes:

[0028] Guide plates are arranged circumferentially along the pipe to be processed, and guide wheels are movably mounted on guide rails;

[0029] A support component is provided on the side of the guide plate opposite to the base assembly. The side of the support component opposite to the guide plate is used to connect the pipe to be processed.

[0030] In one feasible embodiment, the pipe welding apparatus further includes:

[0032] The first and second directions are different from the third direction.

[0033] Compared with the prior art, this disclosure has at least the following beneficial effects: The pipe welding device provided in the embodiments of this disclosure includes a welding tool assembly, a first driving assembly and a second driving assembly, wherein the welding tool assembly is used to weld the pipe to be processed, and the first driving assembly and the second driving assembly are both connected to the welding tool assembly to drive the welding tool assembly to move, so as to facilitate the welding tool assembly to perform the bar movement action, the direction of the first driving assembly driving the welding tool assembly to move is different from the direction of the second driving assembly driving the welding tool assembly to move, and the first driving assembly and the second driving assembly can both operate independently. Based on the aforementioned configuration, the pipe welding apparatus provided in this embodiment facilitates the alteration of the welding tool assembly's electrode movement by adjusting the operating combination of the drive components.

This results in relatively low complexity of the welding tool assembly's movement, enabling it to perform relatively simple electrode movement actions. When both the first and second drive components are operating simultaneously, the welding tool assembly can move under their combined drive. The output parameters of both the first and second drive components influence the actual movement parameters of the welding tool assembly. Consequently, the actual movement of the welding tool assembly can be decomposed into movement in the first direction and movement in the second direction. This allows the pipe welding apparatus to easily change the actual direction and trajectory of the welding tool assembly by adjusting the output parameters of the first and second drive components, improving the welding tool assembly's movement flexibility and enabling it to perform relatively complex electrode movement actions. This enhances the adaptability of the pipe welding apparatus to complex electrode movement patterns, improves the processing quality when performing welding processes with complex electrode movement patterns, and ultimately increases the pass rate of pipe welding operations while reducing operating costs.

[0048] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0049] like Figures 1 to 5As shown, an embodiment of this disclosure provides a pipe welding apparatus, comprising: a welding fixture assembly 100 for welding a pipe to be processed; a first drive assembly 200 connected to the welding fixture assembly 100 for driving the welding fixture assembly 100 to move along a first direction; and a second drive assembly 300 connected to the welding fixture assembly 100 for driving the welding fixture assembly 100 to move along a second direction, the second direction being different from the first direction; wherein the first drive assembly 200 and the second drive assembly 300 can operate independently.

[0050] The pipe welding apparatus provided in this embodiment includes a welding tool assembly 100, a first drive assembly 200, and a second drive assembly 300. The welding tool assembly 100 is used to weld the pipe to be processed. The first drive assembly 200 and the second drive assembly 300 are both connected to the welding tool assembly 100 to drive the welding tool assembly 100 to move, so that the welding tool assembly 100 can perform bar manipulation. The direction of movement of the welding tool assembly 100 driven by the first drive assembly 200 is different from the direction of movement of the welding tool assembly 100 driven by the second drive assembly 300. The first drive assembly 200 and the second drive assembly 300 can both operate independently.

[0051] Based on the aforementioned configuration, the pipe welding apparatus provided in this embodiment facilitates changing the electrode movement pattern of the welding tool assembly 100 by adjusting the operating combination of the drive components. Specifically, when the first drive component 200 or the second drive component 300 is operating, the welding tool assembly 100 can move accordingly along the first or second direction. This results in a relatively low complexity in the movement of the welding tool assembly 100, enabling it to perform relatively simple electrode movement actions. When the first drive component 200 and the second drive component 300 operate simultaneously, the welding tool assembly 100 can move under the combined drive of the first drive component 200 and the second drive component 300. The output parameters of the first drive component 200 and the second drive component 300... The output parameters can all affect the actual motion parameters of the welding fixture assembly 100. Accordingly, the actual motion of the welding fixture assembly 100 can be decomposed into motion in the first direction and motion in the second direction. Thus, the pipeline welding device can easily change the actual motion direction and trajectory of the welding fixture assembly 100 by adjusting the output parameters of the first drive assembly 200 and the second drive assembly 300, thereby improving the motion flexibility of the welding fixture assembly 100. This facilitates the welding fixture assembly 100 in performing relatively complex electrode manipulation actions, enhances the adaptability of the pipeline welding device to complex electrode manipulation, improves the processing quality of the pipeline welding device when performing welding processes with complex electrode manipulation, and helps to improve the pass rate of pipeline welding operations and reduce operating costs.

[0052] It should be noted that traditional automatic welding equipment typically uses linear electric modules or electric cylinders to drive the welding torch for welding pipes. As a result, automatic welding equipment can often only perform welding processes with linear or linear reciprocating welding techniques. However, for welding processes with relatively complex welding techniques such as arc, crescent, and figure-eight shapes, the welding torch movement and the overall movement of the automatic welding equipment often need to be coordinated. Consequently, when welding pipes with relatively complex welding techniques, the automatic welding equipment needs to move at a high frequency relative to the pipe to be processed, which seriously reduces the stability of the automatic welding equipment and leads to poor welding quality.

[0053] Compared to traditional automated welding equipment, the pipe welding apparatus provided in this disclosure can easily change the electrode manipulation pattern of the welding fixture assembly 100 by adjusting the operating combination of the drive components, thus expanding the actual movement directions that the welding fixture assembly 100 can perform. For example, when the first drive component 200 and the second drive component 300 are operating simultaneously, the pipe welding apparatus can easily change the actual movement direction and trajectory of the welding fixture assembly 100 by adjusting the output parameters of the first drive component 200 and the second drive component 300. This improves the movement flexibility of the welding fixture assembly 100, facilitates the execution of relatively complex electrode manipulation movements, enhances the adaptability of the pipe welding apparatus to complex electrode manipulation patterns, and reduces the overall movement requirements of the pipe welding apparatus when performing welding processes with relatively complex electrode manipulation patterns. This is beneficial for improving the stability and reliability of the pipe welding apparatus when performing welding processes with complex electrode manipulation patterns, and improving the processing quality of the pipe welding apparatus when performing welding processes with complex electrode manipulation patterns.

[0054] It is understandable that when the first drive component 200 and the second drive component 300 operate simultaneously, the power output by the first drive component 200 and the second drive component 300 will both act on the welding fixture assembly 100. Thus, the actual motion parameters of the welding fixture assembly 100 are jointly determined by the output parameters of the first drive component 200 and the second drive component 300. Accordingly, the actual motion of the welding fixture assembly 100 has motion components in the first direction and motion components in the second direction. In practical applications, it is convenient to change the motion direction of the welding fixture assembly 100 and parameters such as displacement and motion speed in the corresponding motion direction by adjusting the output parameters of the first drive component 200 and the second drive component 300. This reduces the limitations of the welding fixture assembly 100 in terms of motion direction and motion trajectory, and facilitates the welding fixture assembly 100 in performing the welding motion required by the welding motion mode.

[0055] It is understood that the actual motion parameters of the welding fixture assembly 100 may include, but are not limited to, motion direction and motion speed. It is easy to understand that the actual motion of the welding fixture assembly 100 is completed under the drive of the first drive assembly 200 and / or the second drive assembly 300. Therefore, the aforementioned motion parameters can be adjusted by changing the output parameters of the first drive assembly 200 and / or the second drive assembly 300. The output parameters of the first drive assembly 200 and the second drive assembly 300 can be set in combination with the specific motion pattern in practical applications, and no further restrictions are imposed here.

[0056] For example, when the electrode movement pattern is known, the electrode movement to be completed by the welding fixture assembly 100 can be determined, so that the aforementioned electrode movement can be decomposed into movement components in a first direction and a second direction, and the output parameters of the first drive assembly 200 and the second drive assembly 300 can be determined based on the aforementioned movement components. In practical applications, the operation of the first drive assembly 200 and the second drive assembly 300 can be controlled by determining the obtained output parameters so that the welding fixture assembly 100 performs the corresponding electrode movement.

[0057] It is understood that the movement of the welding fixture assembly 100 along the first direction can be linear or rotational; the movement of the welding fixture assembly 100 along the second direction can also be linear or rotational; the specific movement form of the welding fixture assembly 100 along the first or second direction can be set according to actual needs, and no further restrictions are imposed here.

[0058] It is understood that the welding tool assembly 100 may include, but is not limited to, welding tools such as welding guns and welding clamps. In practical applications, the specific type of the welding tool assembly 100 can be set according to actual needs, and no further restrictions are imposed here.

[0059] like Figures 2 to 4 As shown, in some examples, the welding fixture assembly 100 includes: a support arm 110, the output ends of the first drive assembly 200 and the second drive assembly 300 are both hinged to the support arm 110; and a welding fixture body 120, disposed on the support arm 110, for welding the pipe to be processed; wherein, along the extending direction of the support arm 110, the output ends of the first drive assembly 200, the output ends of the second drive assembly 300 and the welding fixture body 120 are arranged at intervals.

[0060] In this technical solution, the welding fixture assembly 100 may include a support arm 110 and a welding fixture body 120. The output ends of the first drive assembly 200 and the second drive assembly 300 are both hinged to the support arm 110. This allows the power output from the first drive assembly 200 and the second drive assembly 300 to act on the support arm 110, driving its movement. Furthermore, the hinged connection between the support arm 110 and the first and second drive assemblies 200 and 300 avoids excessively rigid movement constraints on the support arm 110, thereby improving its flexibility and facilitating movement even when the first and / or second drive assemblies 200 and 300 are in operation. The welding fixture body 120, used for welding the pipe to be processed, is mounted on the support arm 110, allowing it to move synchronously with the support arm 110 to perform the welding electrode manipulation. Meanwhile, along the extension direction of the support arm 110, the output end of the first drive assembly 200, the output end of the second drive assembly 300, and the welding fixture body 120 can be arranged at intervals. This reduces the possibility of mutual interference between the output ends of the first drive assembly 200, the second drive assembly 300, and the welding fixture body 120 when the support arm 110 is in motion. This helps to improve the motion stability and reliability of the welding fixture assembly 100 and provides further assurance for improving welding quality.

[0061] It is understandable that the welding tool body 120 can be, but is not limited to, welding tools such as welding guns and welding clamps. In practical applications, the specific type of welding tool assembly 100 can be set according to actual needs, and no further restrictions are imposed here.

[0062] like Figure 4 As shown, in some examples, the first drive assembly 200 includes a first drive member 210 and a first connecting rod 220, one end of which is connected to the first drive member 210 and the other end is hinged to the support arm 110; the second drive assembly 300 includes a second drive member 310, a second connecting rod 320 and a third connecting rod 330, the second drive member 310 is connected to one end of the second connecting rod 320, the other end of the second connecting rod 320 is hinged to one end of the third connecting rod 330, the other end of the third connecting rod 330 is hinged to the support arm 110, and the end of the second connecting rod 320 connected to the second drive member 310 is hinged to the end of the first connecting rod 220 connected to the first drive member 210; wherein, along the extension direction of the support arm 110, the hinge point between the third connecting rod 330 and the support arm 110 is located between the hinge point between the first connecting rod 220 and the support arm 110 and the welding fixture body 120.

[0063] In this technical solution, the first drive assembly 200 may include a first drive member 210 and a first connecting rod 220. Correspondingly, the second drive assembly 300 may include a second drive member 310 and a second connecting rod 320. Based on the aforementioned configuration, each connecting rod and support arm 110 can be connected to form a quadrilateral linkage mechanism. The first drive member 210 and the second drive member 310 can provide power for the movement of the aforementioned quadrilateral linkage mechanism. Thus, based on the aforementioned configuration, when the first drive member 210 operates alone, the first connecting rod 220 can serve as the active member in the aforementioned quadrilateral linkage mechanism, and the second connecting rod 320 can serve as the frame of the aforementioned quadrilateral linkage mechanism. The first drive member 210 can drive the welding fixture body 120 along the aforementioned quadrilateral linkage mechanism. The first drive member 310 rotates in the first direction. When the second drive member 310 operates alone, the second link 320 can act as the active member in the aforementioned quadrilateral linkage mechanism, and the first link 220 can act as the frame of the aforementioned quadrilateral linkage mechanism. The second drive member 310 can drive the welding fixture body 120 to rotate in the second direction through the aforementioned quadrilateral linkage mechanism. When the first drive member 210 and the second drive member 310 operate simultaneously, both the first link 220 and the second link 320 can act as the active members of the aforementioned quadrilateral linkage mechanism. The direction and trajectory of the welding fixture body 120 will be affected by the output parameters of the first drive member 210 and the second drive member 310, so that the welding fixture body 120 can perform relatively complex electrode manipulation actions.

[0064] Meanwhile, based on the aforementioned configuration, a relatively close transmission relationship can be formed between the first drive component 200 and the second drive component 300. That is, the power output by each drive component can be transmitted to the welding fixture body 120 through the aforementioned quadrilateral linkage mechanism. This avoids configuring independent transmission mechanisms for each drive component, thereby improving the structural integration of the pipeline welding device and thus helping to improve the miniaturization and lightweighting of the pipeline welding device.

[0065] In some feasible examples, the length of the first link 220 can be set to be the same as the length of the third link 330, and the length of the second link 320 can be set to be the same as the distance from the end of the first link 220 connected to the support arm 110 to the end of the third link 330 connected to the support arm 110. Thus, the aforementioned links and support arms 110 can be connected to form a parallelogram linkage mechanism, which is beneficial to further improve the motion stability and reliability of the welding fixture body 120.

[0066] It is understood that the aforementioned first driving component 210 and the aforementioned second driving component 310 can be, but are not limited to, electric motors.

[0067] like Figure 5As shown, in some examples, the first drive assembly 200 further includes a first reduction mechanism 230 connected between the first drive member 210 and the first link 220; and / or the second drive assembly 300 further includes a second reduction mechanism 340 connected between the second drive member 310 and the second link 320.

[0068] In this technical solution, the first drive assembly 200 may further include a first deceleration mechanism 230, which is disposed between the first drive member 210 and the first connecting rod 220. Thus, the power output by the first drive member 210 can be further transmitted to the first connecting rod 220 through the first deceleration mechanism 230, which is beneficial to further improve the motion stability of the first connecting rod 220, thereby improving the motion stability and reliability of the welding fixture body 120.

[0069] In this technical solution, the second drive assembly 300 may further include a second deceleration mechanism 340, which is disposed between the second drive member 310 and the second connecting rod 320. Thus, the power output by the second drive member 310 can be further transmitted to the second connecting rod 320 through the second deceleration mechanism 340, which is beneficial to further improve the motion stability of the second connecting rod 320, thereby improving the motion stability and reliability of the welding fixture body 120.

[0070] It is understood that the pipe welding device may include the aforementioned first deceleration mechanism 230 and second deceleration mechanism 340 to make the movement of the welding tool assembly 100 more reliable and stable.

[0071] like Figure 5 As shown, in some examples, both the first reduction structure and the second reduction mechanism 340 are gear mechanisms.

[0072] In this technical solution, both the first deceleration structure and the second deceleration mechanism 340 can be gear mechanisms. That is, the first drive assembly 200 may include a gear mechanism connected between the first connecting rod 220 and the first drive member 210, and / or the second drive assembly 300 may include a gear mechanism connected between the second connecting rod 320 and the second drive member 310. It is understood that gear mechanisms can have good stability when transmitting power, which is conducive to further ensuring the stable and reliable movement of the welding fixture assembly 100, thereby providing further assurance for improving welding quality.

[0073] For example, such as Figure 5As shown, the first connecting rod 220, which connects to one end of the first driving member 210, and the second connecting rod 320, which connects to one end of the second driving member 310, can both have connecting shafts. The connecting shafts of the first connecting rod 220 and the second connecting rod 320 are arranged coaxially. For example, the connecting shaft of the first connecting rod 220 can pass through the second connecting rod 320 to further improve the structural compactness of the pipe welding device. Correspondingly, the first reduction mechanism 230 may include a first gear and a second gear. The connecting shaft of the first connecting rod 220 can be fitted with the first gear, and the output end of the first driving member 210 can be provided with the second gear, which meshes with each other. The second reduction mechanism 340 may include a third gear and a fourth gear. The connecting shaft of the second connecting rod 320 can be fitted with the third gear, and the output end of the second driving member 310 can be provided with the fourth gear, which meshes with each other.

[0074] It is understandable that, considering the smooth rotation of the first link 220 and the second link 320, a bearing can be provided between the first link 220 and the second link 320, and the outer peripheral wall of the second link 320 can also be fitted with a bearing.

[0075] like Figures 1 to 5 As shown, in some examples, the pipe welding apparatus further includes: a base assembly 400, a first drive assembly 200 and a second drive assembly 300 both disposed on the base assembly 400; and a motion assembly 500 disposed on the base assembly 400 for driving the base assembly 400 to move circumferentially along the pipe to be processed.

[0076] In this technical solution, the pipe welding device may further include a base assembly 400 and a motion assembly 500. The first drive assembly 200 and the second drive assembly 300 are both mounted on the base assembly 400, thus providing support for both components and improving their stability during use. The motion assembly 500 is mounted on the base assembly 400. In practical applications, the motion assembly 500 drives the base assembly 400 to move circumferentially along the pipe to be processed. This facilitates adjusting the position of the pipe welding device relative to the pipe, allowing for welding at different circumferential positions on the pipe. This further enhances the automation level and ease of use of the pipe welding device, reduces manual intervention in the welding process, and saves on welding costs.

[0077] like Figure 5As shown, in some examples, the base assembly 400 forms an installation space 401, at least a portion of the first drive assembly 200 and at least a portion of the second drive assembly 300 are disposed within the installation space 401, and the welding fixture assembly 100 is located outside the installation space 401.

[0078] In this technical solution, the base assembly 400 can form an installation space 401, in which at least a portion of the first drive assembly 200 and at least a portion of the second drive assembly 300 are disposed. Thus, the base assembly 400 can further provide structural protection for the first drive assembly 200 and the second drive assembly 300, reducing the probability of damage to the first drive assembly 200 and the second drive assembly 300, which is beneficial for extending the service life of the pipe welding device and reducing the maintenance cost of the pipe welding device. Simultaneously, the welding tool assembly 100 can be located outside the installation space 401 to facilitate welding of the pipe to be processed by the welding device, reducing the impact of movement between the base assembly 400 and the welding tool assembly 100, and ensuring the flexibility of movement of the welding tool assembly 100.

[0079] For example, such as Figure 5 As shown, the first drive member 210 and the first reduction mechanism 230 of the first drive assembly 200 can be disposed in the installation space 401, and the second drive member 310 and the second reduction mechanism 340 of the second drive assembly 300 can also be disposed in the installation space 401. Correspondingly, the outer ring of the bearing sleeved on the connecting shaft of the second connecting rod 320 can be fixedly disposed inside the base assembly 400.

[0080] like Figures 1 to 4 As shown, in some examples, the motion component 500 includes: a guide rail 510 for circumferential arrangement along the pipe to be processed; a guide wheel 520 movably disposed on the guide rail 510; and a third drive member 530 disposed on the base assembly 400, the guide wheel 520 being connected to the third drive member 530, the third drive member 530 being used to drive the guide wheel 520 to move along the guide rail 510.

[0081] In this technical solution, the motion component 500 may further include a guide rail 510, a guide wheel 520, and a third drive component 530. The guide rail 510 is arranged circumferentially along the pipe to be processed in practical applications. The guide wheel 520 is movably mounted on the guide rail 510 and connected to the third drive component 530, allowing the guide wheel 520 to receive power output from the third drive component 530 and move along the guide rail 510 under the drive of the third drive component 530. Correspondingly, under the drive of the guide wheel 520, the third drive component 530, the base assembly 400, and other components mounted on the base assembly 400 can also move synchronously along the guide rail 510, thereby enabling the base assembly 400 to move circumferentially along the pipe to be processed. This allows for welding processing at different positions circumferentially along the pipe. Furthermore, based on the aforementioned arrangement, the probability of the moving parts of the pipe welding device directly contacting the pipe to be processed can be reduced, which is beneficial for improving the motion stability of the pipe welding device and reducing the risk of damaging the surface of the pipe during welding, providing further reliable assurance for improving processing quality.

[0082] It is understandable that the guide rail 510 can be an arc-shaped structure. In practical applications, the guide rail 510 can be fixedly set on the periphery of the pipe to be processed, and the guide rail 510 can maintain a high degree of circumferential consistency with the pipe to be processed. Thus, during the movement of the base assembly 400 along the guide rail 510, a corresponding displacement along the circumferential direction of the pipe to be processed can be generated.

[0083] For example, such as Figures 1 to 4 As shown, the aforementioned guide wheels 520 can be four in number. These four guide wheels 520 can be symmetrically arranged on both sides of the guide rail 510 along its axial direction, thereby further improving the stability and reliability of the motion component 500 and providing a reliable guarantee for the smooth and stable movement of the base component 400 along the circumferential direction of the pipe to be processed. It is understood that the number of guide wheels 520 is not limited to four; other numbers are also possible. In practical applications, the number can be set according to specific requirements, and no further limitations are imposed here.

[0084] like Figure 1 As shown, in some examples, the guide rail 510 includes: a guide plate 511 for circumferential arrangement along the pipe to be processed, and a guide wheel 520 movably disposed on the guide rail 510; and a support member 512 disposed on the side of the guide plate 511 opposite to the base assembly 400, the side of the support member 512 opposite to the guide plate 511 for connecting the pipe to be processed.

[0085] In this technical solution, the guide rail 510 may include a guide plate 511 and a support member 512. The support member 512 is disposed on the side of the guide plate 511 away from the base assembly 400 and is used to connect the pipe to be processed. The guide wheel 520 is movably disposed on the guide plate 511, and the guide plate 511 is arranged circumferentially along the pipe to be processed. Based on the aforementioned arrangement, the guide plate 511 can be supported by the support member 512 in practical applications. As a result, during the movement of the guide wheel 520 along the guide plate 511, the probability of the guide wheel 520 directly contacting the periphery of the pipe to be processed can be reduced, further reducing the risk of damaging the surface of the pipe to be processed during welding, and providing a further reliable guarantee for improving the processing quality.

[0086] like Figure 1 , Figure 3 and Figure 4 As shown, in some examples, the pipe welding apparatus further includes a third drive assembly 600 connected to the welding fixture assembly 100. When the guide rail 510 is arranged circumferentially along the pipe to be processed, the third drive assembly 600 is used to drive the welding fixture assembly 100 to move in a third direction so that the welding fixture assembly 100 approaches or moves away from the pipe to be processed; wherein the first direction and the second direction are different from the third direction.

[0087] In this technical solution, the pipe welding apparatus may further include a third drive assembly 600 connected to the welding fixture assembly 100. When the guide rail 510 is arranged circumferentially along the pipe to be processed, the third drive assembly 600 is used to drive the welding fixture assembly 100 to move along a third direction, so that the welding fixture assembly 100 moves closer to or away from the pipe to be processed. Based on the aforementioned arrangement, the movement flexibility of the welding fixture assembly 100 can be further improved, which is beneficial to improving the adaptability of the pipe welding apparatus to pipes of different shapes and enhancing the welding process execution capability of the pipe welding apparatus.

[0088] For example, the first direction and the second direction can be two different directions in the same plane, and the third direction can be a direction that passes through the plane where the first direction and the second direction are located. In this way, when the first direction, the second direction and the third direction are different, the motion freedom of the welding fixture assembly 100 can be further improved, which is beneficial to enhance the adaptability of the welding fixture assembly 100 to different welding rod forms.
