[0037] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0038] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0039] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0040] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0041] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0042] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0043] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0044] like Figures 1 to 2 As shown, the welding device provided in the present application includes a welding machine 100, a wire feeder 200 and a connecting assembly. The connecting assembly is used to install the wire feeder 200 on the welding machine 100, which not only ensures the stability of the wire feeder 200, but also enables the wire feeder 200 to be quickly disassembled and assembled, thereby improving assembly efficiency and facilitating welding operations for welders.

[0045] For example, the connection method of the welding machine 100, the wire feeder 200 and the connection assembly can be: Figures 3 and 4 Combined with Figure 2 As shown, the top cover 1 of the welding machine 100 has a threaded hole 121; the chassis 2 of the wire feeder 200 has a plug hole 2221 and a mounting hole 2222 perpendicularly arranged to the plug hole 2221 and connected to the plug hole 2221; the connecting assembly includes a connecting shaft 3 and a locking member 4, one end of the connecting shaft 3 has an external thread 31 that cooperates with the threaded hole 121, and the other end thereof has a plug portion 32 that cooperates with the plug hole 2221, and one end of the locking member 4 can pass through the mounting hole 2222 and abut against the plug portion 32.

[0046] In actual application, the connecting shaft 3 is first screwed into the threaded hole 121 of the top cover 1 of the welding machine 100, and then the plug hole 2221 of the wire feeder 200 is aligned with the plug part 32 of the connecting shaft 3, and the plug part 32 is inserted into the plug hole 2221. Finally, the locking piece 4 is passed through the mounting hole 2222, and the locking piece 4 is abutted against the plug part 32, so that the wire feeder 200 can be fixedly installed, which can not only prevent the wire feeder 200 from rotating relative to the connecting shaft 3, but also prevent the wire feeder 200 from moving up and down.

[0047] like Figure 6 Combine Figure 3 and Figure 4 As shown, the top cover 1 includes a top cover body 11 and a threaded sleeve 12. The threaded sleeve 12 is provided with a threaded hole 121 and is fixed to the top cover body 11. This arrangement eliminates the need to thicken the top cover body 11 as a whole to ensure that the threaded hole 121 has sufficient threads for threaded connection with the connecting shaft 3. It is only necessary to ensure that the thickness of the threaded sleeve 12 meets the requirements, which can reduce the cost and weight of the top cover 1. Furthermore, the threaded hole 121 of the threaded sleeve 12 is a blind hole, which can limit the installation depth of the connecting shaft 3.

[0048] Furthermore, the outer wall of the connecting shaft 3 has two parallel, symmetrically arranged flat surfaces 33 for gripping with a wrench. These flat surfaces 33 are located between the external threads 31 and the inserting portion 32. The provision of these two parallel, symmetrically arranged flat surfaces 33 facilitates gripping the connecting shaft 3 with a wrench and screwing the external threads 31 of the connecting shaft 3 into the threaded hole 121 of the threaded sleeve 12, improving assembly efficiency.

[0049] In this embodiment, the threaded sleeve 12 is fixed to the lower surface of the top cover body 11. The top cover body 11 is provided with a first through-hole 111 that communicates with the threaded hole 121. This arrangement ensures a smooth upper surface of the top cover body 11. The end of the threaded sleeve 12 has a positioning protrusion that mates with the first through-hole 111. The positioning protrusion is inserted into the first through-hole 111, thereby achieving the fixed installation of the threaded sleeve 12. Furthermore, the periphery of the threaded sleeve 12 is fixedly connected to the top cover body 11 by welding to ensure the connection strength.

[0050] To improve the overall structural strength of the top cover 1, the top cover 1 further includes a threaded sleeve reinforcement rib 13 and a top cover reinforcement rib 14. The threaded sleeve reinforcement rib 13 is fixed to the lower surface of the threaded sleeve 12, and the top cover reinforcement rib 14 is fixed to the lower surface of the top cover body 11 and fixedly connected to the threaded sleeve reinforcement rib 13. Specifically, the threaded sleeve reinforcement rib 13 extends along the width direction of the top cover body 11, and the top cover reinforcement rib 14 is connected to both ends of the threaded sleeve reinforcement rib 13 in the longitudinal direction.

[0051] The assembly process of the top cover 1 is as follows: insert the positioning protrusion at the end of the threaded sleeve 12 into the first through hole 111 of the top cover body 11, and then weld the periphery of the threaded sleeve 12 to the top cover body 11; then weld the threaded sleeve reinforcement rib 13 to the bottom of the threaded sleeve 12; then weld the top cover reinforcement rib 14 to the top cover 1 and the threaded sleeve reinforcement rib 13, so that the top cover 1 becomes a stable rigid structure and will not be deformed due to the placement of the wire feeder 200.

[0052] like Figure 7 Combine Figure 5As shown, the chassis 2 includes a chassis body 21 and a sleeve 22. The sleeve 22 is provided with an insertion hole 2221 and a mounting hole 2222. The sleeve 22 is fixed to the chassis body 21. This arrangement eliminates the need to thicken the chassis body 21 as a whole to ensure that the insertion hole 2221 has sufficient depth to mate with the insertion portion 32 of the connecting shaft 3. It is only necessary to ensure that the thickness of the sleeve 22 meets the requirements, thereby reducing the cost and weight of the chassis 2.

[0053] In this embodiment, the shaft sleeve 22 includes a small shaft section 221 and a large shaft section 222 connected in a stepped manner. The large shaft section 222 is provided with a plug hole 2221 and a mounting hole 2222. The chassis body 21 is provided with a second through hole 211 for the small shaft section 221 to pass through. The step surface between the small shaft section 221 and the large shaft section 222 abuts against the lower surface of the chassis body 21. Such an arrangement not only realizes the positioning and installation of the shaft sleeve 22, but also facilitates the welding and fixing of the shaft sleeve 22 to the chassis body 21. Furthermore, the small shaft section 221 has an exhaust through hole 2211 connected to the plug hole 2221 for exhausting air to avoid forming a closed space between the plug portion 32 of the connecting shaft 3 and the plug hole 2221 of the shaft sleeve 22, which is difficult to plug in and out.

[0054] See also Figure 3 As shown, the end of the plug-in portion 32 of the connecting shaft 3 has a chamfer 321 to facilitate smooth insertion of the plug-in portion 32 into the plug-in hole 2221 of the chassis 2, thereby improving assembly efficiency.

[0055] Furthermore, the chassis 2 includes a sleeve reinforcement rib 23 having a third through-hole for the main shaft section 222 to pass through. The main shaft section 222 is fixedly connected to the sleeve reinforcement rib 23, and both ends of the sleeve reinforcement rib 23 are fixedly connected to the chassis body 21. This arrangement not only improves the installation strength of the sleeve 22, but also improves the overall structural strength of the chassis 2.

[0056] The assembly process of the chassis 2 is as follows: insert the sleeve 22 into the second through hole 211 of the chassis body 21, and then weld the periphery of the sleeve 22 to the chassis body 21; then weld the sleeve reinforcement rib 23 to the sleeve 22, and weld the sleeve reinforcement rib 23 to the chassis body 21, so that the chassis 2 becomes a stable rigid structure that will not be deformed due to use.

[0057] like Figure 8 As shown, the locking member 4 includes a screw portion 41 and a knob portion 42. The screw portion 41 is threadedly connected to the mounting hole 2222 and can abut against the plug portion 32 of the connecting shaft 3. The knob portion 42 is used to facilitate workers to hand-twist the locking member 4, improving the convenience of operation. For example, the locking member 4 can be a plum blossom-shaped locking screw.

[0058] The welding device provided in the present application can quickly install the wire feeder 200 on the welding machine 100, which can not only ensure the stability of the wire feeder 200, but also improve the assembly efficiency, thereby improving the welding efficiency.

[0059] The above shows and describes the basic principles, main features and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of this application.
