[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] This application provides an auxiliary tool, please refer to Figure 1 , Figure 2 and Figure 6 The auxiliary tool includes a base 1 and an upper plate 2, the base 1 is used to accommodate the welding equipment 3, the base 1 is provided with a first conductive part 11, the upper plate 2 is provided with a plug-in channel 21 for the welding equipment 3 to pass through, and the upper plate 2 is provided with a second conductive part 22, wherein the upper plate 2 can move relative to the base 1, when the deflection angle of the welding equipment 3 relative to the base 1 is not greater than a threshold value, the first conductive part 11 and the second conductive part 22 are arranged at intervals; when the deflection angle of the welding equipment 3 relative to the base 1 is greater than a threshold value, the welding equipment 3 drives the upper plate 2 to move relative to the base 1, so that the first conductive part 11 and the second conductive part 22 abut against each other, and are electrically conductive to trigger a prompt.

[0037] It is understandable that when the welding device 3 deflects relative to the base 1, the welding device 3 will drive the upper plate 2 to move relative to the base 1, so that the first conductive part 11 and the second conductive part 22 move relative to each other. The larger the deflection angle of the welding device 3, the larger the moving distance of the second conductive part 22. When the deflection angle is not greater than the threshold, the first conductive part 11 and the second conductive part 22 are still arranged at intervals. At this time, the first conductive part 11 and the second conductive part 22 are not electrically connected, and the prompt will not be triggered; when the deflection angle is greater than the threshold, the second conductive part 22 moves to the first conductive part 11 and abuts against the first conductive part 11. At this time, the first conductive part 11 and the second conductive part 22 are electrically connected and a prompt will be triggered, so that the operator can promptly know that the deflection angle of the welding device 3 is too large at this time, and the operator can promptly adjust the deflection angle of the welding device 3 to within the threshold, thereby ensuring the welding quality.

[0038] Compared to visually judging whether the deflection angle of the welding equipment 3 is too large, the present application can determine whether the deflection angle of the welding equipment 3 is greater than a threshold by observing whether a prompt is triggered, thereby improving the accuracy of judging the deflection angle of the welding equipment 3, and can control the deflection angle of the welding equipment 3 within a reasonable range, thereby ensuring the welding quality.

[0039] In some examples, when the deflection angle is not greater than a threshold value, the upper plate 2 and the base 1 may be spaced apart or may abut against each other, and the second conductive portion 22 may be spaced apart from the base 1 .

[0040] In some examples, the auxiliary tool may include an alarm component, which is electrically connected to at least one of the first conductive portion 11 and the second conductive portion 22. When the first conductive portion 11 and the second conductive portion 22 abut against each other, the alarm component will be triggered and an alarm prompt will be issued. The auxiliary tool may also include a circuit connection detection element for detecting whether the first conductive portion 11 and the second conductive portion 22 are electrically connected. When the circuit connection detection element detects that the first conductive portion 11 and the second conductive portion 22 are electrically connected, a prompt will be issued.

[0041] In some examples, the prompt can be set as needed, such as a sound prompt or a light prompt.

[0042] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 The first conductive part 11 includes a first end face 111 facing the upper plate 2, the upper plate 2 includes a second end face 23 attached to the first end face 111, the second end face 23 includes a second conductive part 22 capable of conducting electricity and an insulating part 24, the insulating part 24 and the second conductive part 22 are nested, when the deflection angle of the welding device 3 relative to the base 1 is not greater than a threshold value, the first end face 111 is attached to the insulating part 24, and the base 1 and the second conductive part 22 are spaced apart; when the deflection angle of the welding device 3 relative to the base 1 is greater than a threshold value, the welding device 3 drives the upper plate 2 to move relative to the base 1 so that the second conductive part 22 abuts against the first end face 111.

[0043] It is understandable that when the welding device 3 deflects relative to the base 1, the welding device 3 will drive the upper plate 2 to move relative to the base 1, so that the first end face 111 and the second end face 23 move relative to each other. The larger the deflection angle, the greater the distance the upper plate 2 moves driven by the welding device 3. When the deflection angle is not greater than the threshold, the first end face 111 is in contact with the insulating part 24 that cannot conduct electricity, and the prompt will not be triggered at this time; when the deflection angle is greater than the threshold, the first end face 111 will be in contact with the second conductive part 22, and a prompt will be triggered at this time, so that the operator can promptly know that the deflection angle of the welding device 3 is too large at this time, so that the operator can promptly adjust the deflection angle of the welding device 3 to within the threshold.

[0044] In some examples, the entire base 1 may be electrically conductive.

[0045] In some examples, when the second conductive portion 22 and the first end face 111 are in contact, since both the second conductive portion 22 and the first end face 111 are conductive, the second conductive portion 22 and the first end face 111 form a loop, and an alarm is provided in the loop so that the alarm is triggered and a prompt is issued.

[0046] In some examples, the second conductive portion 22 and the insulating portion 24 may be annular structures. Of course, the second conductive portion 22 and the second end portion may also be any other suitable structures, such as a rectangular structure.

[0047] In some examples, the second conductive portion 22 may be sleeved outside the insulating portion 24 , and the area of ​​the second end surface 23 is larger than the area of ​​the first end surface 111 , so that when the deflection angle is not greater than a threshold, the insulating portion 24 abuts against the first end surface 111 .

[0048] In some examples, the insulating portion 24 may be sleeved outside the second conductive portion 22 , and the second end surface 23 may overlap with the first end surface 111 . When the deflection angle is not greater than a threshold, the insulating portion 24 abuts against the first end surface 111 .

[0049] In some embodiments, the auxiliary tool includes an elastic connector, and the upper plate 2 is connected to the base 1 via the elastic connector.

[0050] It can be understood that by connecting the upper plate 2 and the base 1 through an elastic connecting member, the upper plate 2 can be moved relative to the base 1, and the fit between the first end face 111 and the second end face 23 can be ensured, ensuring that when the deflection angle of the welding equipment 3 is greater than the threshold, the second conductive part 22 will abut against the first end face 111.

[0051] It can be understood that the elastic connecting member can make the second end face 23 at least partially always keep in contact with the first end face 111, so that when the deflection angle is greater than the threshold, the second conductive part 22 at least partially abuts against the first end face 111, ensuring that the alarm can be successfully triggered when the deflection angle is greater than the threshold.

[0052] In some embodiments, reference Figure 1 and Figure 2 The upper plate 2 is provided with a plurality of first connection holes 25, and the base 1 is provided with a plurality of second connection holes 12. The plurality of first connection holes 25 and the plurality of second connection holes 12 are arranged opposite to each other one by one, and the elastic connecting member is passed through the first connection holes 25 and the second connection holes 12 to connect the upper plate 2 and the base 1.

[0053] It can be understood that the elastic connector is inserted into the first connection hole 25 and the second connection hole 12 so that the elastic connector can connect the upper plate 2 and the base 1 together. When the welding device 3 deflects, the elastic connector can be deformed, and the upper plate 2 can move under the drive of the welding device 3. At the same time, since the elastic connector also applies a pulling force to the upper plate 2, the fit between the upper plate 2 and the base 1 can be ensured.

[0054] In some examples, the plurality of first connection holes 25 includes at least two first connection holes 25 , and the plurality of second connection holes 12 includes at least two second connection holes 12 .

[0055] In some examples, the number of elastic connectors may be one or more. When there is one elastic connector, the elastic connector is sequentially inserted into all the first connection holes 25 and the second connection holes 12 to achieve elastic connection between the upper plate 2 and the base 1; when there are multiple elastic connectors, one of the elastic connectors may be inserted into one of the first connection holes 25 and the corresponding second connection hole 12. It should be noted that the above is only an example of the number and connection method of the elastic connectors, and does not limit the number and connection method of the elastic connectors.

[0056] Exemplarily, the elastic connecting member is, for example, a soft rubber strip or a rubber strip or any other suitable elastic connecting member.

[0057] In some embodiments, reference Figure 2 and Figure 6 A rotating cavity 13 is formed in the base 1 , and the plug-in channel 21 is connected to the rotating cavity 13 . The rotating cavity 13 is used to accommodate the electrode cap 31 of the welding device 3 and allows the electrode cap 31 to rotate in the rotating cavity 13 .

[0058] It is understandable that when the welding device 3 deflects, the electrode cap 31 can rotate in the rotating cavity 13, which can avoid the situation where the electrode cap 31 cannot rotate freely and affects the use of the welding device 3. In other words, the welding device 3 can be deflected and adjusted within the range of the deflection angle not greater than the threshold, ensuring the rotational freedom of the welding device 3, so that the welding device 3 can adapt to different welding requirements.

[0059] In some examples, the inner wall surface of the rotating cavity 13 is a spherical surface matching the electrode cap 31 , so that the electrode cap 31 can be rotated in the cavity 13 to be tilted at multiple angles.

[0060] In some embodiments, reference Figure 2 and Figure 4 The base 1 includes a side wall 14 and a fastener 15. The side wall 14 is used to be arranged around the welding device 3 and can be deformed toward the welding device 3. The fastener 15 is sleeved on the side wall 14 and allows the side wall 14 to deform to fix the side wall 14 and the welding device 3.

[0061] It can be understood that the external force is applied to the side wall 14 of the base 1 by the fastener 15, so that the side wall 14 is deformed toward the welding device 3 and abuts against the welding device 3. The fastener 15 can keep the side wall 14 connected to the welding device 3 to achieve a fixed connection between the side wall 14 and the welding device 3, so that the auxiliary tool can be stably connected to the welding device 3.

[0062] In some examples, the fastener 15 may be an elastic fastener, and when the elastic fastener is sleeved on the side wall 14, the elastic fastener applies an elastic force to the side wall 14, so that the side wall 14 is deformed toward the welding device 3. At the same time, since the elastic fastener itself has the characteristic of elastic deformation, the installation and removal of the fastener 15 are more convenient.

[0063] In some examples, the fastener 15 may also be a non-elastic fastener, such as a rope.

[0064] In some embodiments, reference Figure 2 , Figure 4 and Figure 6 A groove 16 is formed on the side wall 14 of the base 1 , and the fastener 15 is snapped into the groove 16 . The fastener 15 is suitable for deforming the side wall 14 of the base 1 toward the welding device 3 and snapping into the slot 32 of the welding device 3 .

[0065] It is understandable that the groove 16 can limit the fastener 15, so that the fastener 15 is stably sleeved on the side wall 14. The slot 32 can limit the deformed side wall 14, so that the connection between the side wall 14 and the welding device 3 is more stable.

[0066] In some embodiments, the inner diameter of the insertion channel 21 is equal to the diameter of the welding device 3, so that when the welding device 3 is inserted into the insertion channel 21, there is no gap between the welding device 3 and the insertion channel 21. Once the welding device 3 is deflected, it will drive the upper plate 2 to move, thereby avoiding the occurrence of a void between the welding device 3 and the upper plate 2.

[0067] In some embodiments, the outer wall surface of the welding device 3 abuts against the inner wall surface of the plug-in channel 21, so that when the welding device 3 rotates, it will drive the upper plate 2 to move in real time, ensuring that when the deflection angle of the welding device 3 is greater than the threshold, the upper plate 2 will move to the position where the second conductive part 22 abuts against the first conductive part 11.

[0068] In some examples, the outer wall surface of the welding device 3 abuts against the inner wall surface of the plug-in channel 21, which may mean that a protrusion may be formed on the outer wall surface of the welding device 3, and the protrusion extends toward the inner wall surface of the plug-in channel 21 and abuts against the inner wall surface of the plug-in channel 21; the outer wall surface of the welding device 3 abuts against the inner wall surface of the plug-in channel 21, which may also mean that the outer wall surface of the welding device 3 is directly in contact with the inner wall surface of the plug-in channel 21.

[0069] In some embodiments, when the second conductive portion 22 abuts against the first conductive portion 11 , the angle between the central axis of the welding device 3 and the central axis of the base 1 is greater than 5°.

[0070] It can be understood that when the second conductive part 22 and the first conductive part 11 abut against each other, a prompt will be triggered, and the angle between the central axis of the welding equipment 3 and the central axis of the base 1 can be controlled within 5°, that is, the verticality of the welding equipment 3 and the workpiece can be controlled within the range of 85°-95°, which can ensure that spatter or weld distortion will not be caused by the welding posture.

[0071] In some embodiments, the end surface of the base 1 away from the upper plate 2 is a plane, and the end surface of the base 1 away from the upper plate 2 is used to fit with the workpiece to be processed.

[0072] It can be understood that when the end face of the base 1 away from the upper plate 2 is in contact with the workpiece, the base 1 can be perpendicular to the workpiece. The deflection angle between the welding equipment 3 and the base 1 can be used to obtain the verticality between the welding equipment 3 and the workpiece. The deflection angle of the welding equipment 3 can be controlled based on the base 1 to ensure the verticality between the welding equipment 3 and the workpiece.

[0073] In some examples, the welding device 3 is passed through the plug-in channel 21 and is located inside the base 1. The welding device 3 can apply force to the base 1 so that the end surface of the base 1 away from the upper plate 2 is kept in contact with the workpiece, thereby ensuring that the base 1 is always maintained in a state perpendicular to the processing surface of the workpiece.

[0074] In some embodiments, the upper plate 2 includes an inner wall surface surrounding the plug-in channel 21 , and the inner wall surface is provided with an insulating layer.

[0075] It is understandable that the upper plate 2 and the welding device 3 can be separated by the insulating layer to avoid electrical conduction between the welding device 3 and the second conductive part 22, thereby preventing the welding device 3 from affecting the auxiliary tool.

[0076] In some examples, insulating and separating the welding device 3 and the upper plate 2 can avoid triggering a prompt due to electrical conduction between the welding device 3 and the upper plate 2, and can also prevent the current of the welding device 3 from damaging the first conductive part 11 and the second conductive part 22.

[0077] According to a second aspect of the present disclosure, a welding equipment assembly is provided, which includes the auxiliary tool mentioned above, and the welding equipment is inserted into the insertion channel 21. The welding equipment assembly has all the beneficial effects of the above welding equipment assembly, which will not be described in detail in the present disclosure.

[0078] According to a third aspect of the present disclosure, a vehicle production line is provided, which includes the above-mentioned welding equipment assembly. The vehicle production line has all the beneficial effects of the above-mentioned welding equipment assembly, which will not be described in detail in the present disclosure.

[0079] The vehicle production line may be a fuel vehicle production line, a plug-in hybrid vehicle production line, or a new energy vehicle production line, etc., and the present disclosure does not make any specific limitation on this.

[0080] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.

[0081] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0082] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.

[0083] The above are only preferred embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application has been described in examples with different focuses on the description of each embodiment, for the parts not described in detail in a certain embodiment, reference can be made to the relevant effective embodiments of other embodiments.
