Description

Technical Field

[0001] This utility model relates to the field of electric welding machine technology, specifically to an electric welding machine with a quick-change welding gun connector. Background Technology

[0002] Electric welding machines are electrical devices that use electrical energy to convert into heat energy to achieve localized melting and connection of metal materials. They are widely used in industrial manufacturing, construction, maintenance and other fields. The essence of electric welding machines is to reduce voltage and increase current so that electrical energy generates a high-temperature electric arc (or resistance heat) between the electrode and the workpiece, which melts the metal base material and filler materials (such as welding rods and welding wires), and forms a strong welded joint after cooling.

[0003] However, existing welding torch connectors are prone to alignment problems when connecting the welding torch and the welding machine. Alignment takes time and stripping can easily occur if the connection is not made correctly and the installation is forced. Utility Model Content

[0004] The purpose of this invention is to provide a welding machine with a quick-change welding torch connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding machine with a quick-change welding torch connector, comprising a machine body and a convenient protective component. An interface is installed on the front side of the lower end of the machine body. The convenient protective component for quick and stable replacement of the welding torch connector is located outside the interface. The convenient protective component includes an anti-disengagement frame, a locking groove, a welding torch threaded connector, a locking plate, and a welding torch and wiring. A locking groove is provided on the inner side of the anti-disengagement frame. A locking plate is provided inside the locking groove, and a welding torch threaded connector is provided inside the locking plate. The front end of the welding torch threaded connector is connected to the welding torch and wiring.

[0006] Furthermore, there are two anti-detachment frames, and the anti-detachment frames are connected by a locking groove and a locking limit plate.

[0007] Furthermore, the surface of the side of the body is provided with a storage groove, and there are two storage grooves symmetrically arranged about the vertical central axis of the body.

[0008] Furthermore, the storage slot is equipped with a cable bundle assembly for storing welding torch hoses, and the number of cable bundle assemblies is the same as the number of storage slots.

[0009] Furthermore, the wire harness assembly includes a rotating rod and a rotating block, with the rotating block connected to the lower end of the rotating rod.

[0010] Furthermore, the wire harness assembly also includes a mounting hole and a wire harness rod. The mounting hole is provided on the side surface of the rotating rod, and the wire harness rod is installed inside the mounting hole.

[0011] Furthermore, the rotating rod and the mounting hole are an integrated structure, and the mounting hole and the wire harness rod are threaded together.

[0012] Furthermore, the bottom of the machine body is provided with an operating slot, and the machine body and the operating slot are an integrated structure.

[0013] This utility model provides a welding machine with a quick-change welding torch connector, which has the following advantages:

[0014] 1. This utility model uses the anti-detachment bracket and the locking groove to position the locking plate, so that the welding torch threaded connector and the interface are aligned. As the welding torch threaded connector rotates and the interface threaded connection is installed, the welding torch threaded connector moves in the middle of the locking plate. During disassembly, it can be quickly disassembled and replaced by rotating in the opposite direction. After the welding torch threaded connector is installed, the anti-detachment bracket plays a role in limiting and preventing loosening and separation, thereby increasing the connection firmness.

[0015] 2. This utility model uses a storage slot for storing the wire harness assembly when not in use. The rotating rod rotates with the rotation of the rotating block. The equally spaced mounting holes allow the wire harness rod to be installed in any mounting hole as needed. The wire harness rod serves to wind and store the welding gun wires and grounding wires, preventing them from being laid messily on the ground. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2As shown, a welding machine with a quick-change welding torch connector includes a body 1 and a convenient protective component 3. An interface 2 is installed on the front side of the lower end of the body 1. The convenient protective component 3, used for quick and stable replacement of the welding torch connector, is located outside the interface 2. The convenient protective component 3 includes an anti-disengagement bracket 301, a locking groove 302, a locking plate 303, a welding torch threaded connector 304, and a welding torch and wiring 305. The anti-disengagement bracket 301 has a locking groove 302 on its inner side. The anti-disengagement bracket 301 and the locking groove 302 position the locking plate 303, aligning the welding torch threaded connector 304 with the interface 2. A locking mechanism is provided inside the locking groove 302. The limiting plate 303 has a welding gun threaded connector 304 inside. The front end of the welding gun threaded connector 304 is connected to the welding gun and the wiring 305. As the welding gun threaded connector 304 rotates and the interface 2 is threadedly connected and installed, the welding gun threaded connector 304 moves threadedly in the middle of the limiting plate 303. When disassembling, it can be quickly disassembled and replaced by rotating in the opposite direction. There are two anti-detachment brackets 301. The anti-detachment brackets 301 are engaged with the limiting plate 303 through the engagement groove 302. After the welding gun threaded connector 304 is installed, the anti-detachment brackets 301 play a role in limiting and preventing loosening and separation, thereby increasing the connection firmness.

[0022] like Figure 3 As shown, a storage slot 4 is provided on the side surface of the body 1. The storage slot 4 is used to store the wire harness assembly 5 when not in use. There are two storage slots 4 symmetrically arranged about the vertical central axis of the body 1. The wire harness assembly 5 for storing welding gun hose is installed inside the storage slot 4. The number of wire harness assemblies 5 and storage slots 4 are the same. The wire harness assembly 5 includes a rotating rod 501 and a rotating block 502. The lower end of the rotating rod 501 is connected to the rotating block 502. The rotating rod 501 rotates as the rotating block 502 rotates. The wire harness assembly 5 also includes a mounting hole 503 and a wire harness rod 50. 4. The side surface of the rotating rod 501 is provided with mounting holes 503. The mounting holes 503 are evenly distributed so that the wire harness rod 504 can be installed in any mounting hole 503 as needed. The wire harness rod 504 is installed inside the mounting hole 503. The rotating rod 501 and the mounting hole 503 are integrated structures. The mounting hole 503 and the wire harness rod 504 are threaded. The wire harness rod 504 plays the role of winding and storing the welding gun wire and the grounding wire, so as to avoid them being laid messily on the ground. The bottom of the machine body 1 is provided with an operating groove 6. The machine body 1 and the operating groove 6 are integrated structures.

[0023] In summary, this welding machine with a quick-change welding torch connector is first based on... Figures 1-3The structure shown depicts a locking plate 303 that is snapped into the locking groove 302 of the anti-detachment bracket 301 from bottom to top. At this time, the anti-detachment bracket 301 positions the locking plate 303, ensuring that the welding torch threaded connector 304 and the interface 2 are aligned. As the welding torch threaded connector 304 rotates and the interface 2 is threadedly connected, the welding torch threaded connector 304 moves threadedly in the middle of the locking plate 303. During disassembly, the reverse rotation allows for quick disassembly and replacement of a new welding torch. After the welding torch threaded connector 304 is connected, the anti-detachment bracket 301 limits and prevents loosening and separation, increasing the connection strength. When using the welding torch, the hand reaches into the operating groove 6 to operate the rotation of the rotating block 502. The rotating rod 501 rotates with the rotation of the rotating block 502. Then, the cable tie 504 is installed in any mounting hole 503 as needed, so that the cable tie 504 can be used to wind and store the welding torch wiring and grounding wiring, preventing them from being messily laid on the ground.
