Description

Technical Field

[0001] This utility model relates to the field of electric welding equipment, and in particular to a handheld welding machine with a function module switching capability. Background Technology

[0002] Modern welding machines utilize the high temperature generated instantaneously by the positive and negative electrodes to melt the materials being welded, thus bonding the objects together. Common welding materials on the market include welding wire and welding rod.

[0003] Welding wire is highly adaptable to welding various types of steel. Adjusting the composition and ratio of the flux is extremely convenient and easy, providing the required chemical composition of the weld. It has good process performance and produces aesthetically pleasing welds. Using a combination of gas and slag protection, it achieves excellent weld formation. Welding rods enable rapid welding, reducing working time. Compared to other welding methods, welding rods are a highly efficient welding method. However, different welding machines are required for different scenarios, which is inconvenient for workers to carry and use. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a handheld welding machine with switchable function modules, which solves the problem of needing to switch between different welding machines in different scenarios, making it inconvenient to carry and use.

[0005] The technical solution adopted by this utility model is: a handheld welding machine with a function module switching capability, including a shell, welding wire, welding tube, wire feeding device, control module, winding wheel and power supply. The winding wheel is rotatably connected inside the shell, the welding wire is wound on the winding wheel, the wire feeding device transports the welding wire, the welding wire passes through the welding tube, and also includes a welding rod and a mode changing device. The shell is provided with a mounting block, the welding tube and the welding rod are detachably connected to the mounting block, and the mode changing device can switch between welding wire mode and welding rod mode.

[0006] When switching to welding wire mode and the welding tube is connected to the mounting block, the control module and the wire feeding device are electrically connected, and the control module, the mounting block, and the welding wire are electrically connected; when switching to welding electrode mode and the welding electrode is connected to the mounting block, the control module, the mounting block, and the welding electrode are electrically connected.

[0007] Through the above technical solution, the user can switch to the welding wire mode and connect the welding tube to the mounting block, use the control module to control the wire feeding device to transmit the welding wire, and the control module can supply power to the welding wire; the user can also switch to the welding rod mode and connect the welding rod to the mounting block, and the control module controls the supply of power to the welding rod; this utility model can adapt to welding in different scenarios, and is very convenient for users to carry and use.

[0008] Furthermore, both the welding electrode and the welding tube are provided with protrusions, and the mounting block is provided with a connecting hole. The connecting hole is provided with a first recessed channel and a second recessed channel that are interconnected. One end of the first recessed channel is connected to the outer surface of the mounting block, and the second recessed channel extends in the circumferential direction of the connecting hole.

[0009] With the above technical solution, the protrusion first passes through the first recessed channel, and then moves around the trajectory along the second recessed channel to complete the installation. The installation between the welding rod and the welding pipe and the mounting block is simple and convenient.

[0010] Furthermore, along the trajectory path of the second recessed channel and in a direction away from the first recessed channel, the width of the second recessed channel gradually narrows.

[0011] With the above technical solution, the greater the angle at which the protrusion moves in the second recessed channel, the better the connection effect between the welding rod or welding pipe and the mounting block.

[0012] Furthermore, the outer casing has a mounting hole, the mounting block has a mounting part, the mounting part is mounted on the mounting hole, and the mounting hole is adapted to the mounting part.

[0013] With the above technical solution, the mounting hole and mounting part are adapted, the mounting block will not wobble, and it will be more stable during welding and use.

[0014] Furthermore, the mounting block is provided with a first limiting part and a second limiting part, and the outer shell is provided with a fixing plate, which is located between the first limiting part and the second limiting part.

[0015] With the above technical solution, the mounting block is difficult to detach from the outer shell.

[0016] Furthermore, it also includes an extrusion device that presses against the welding wire. A fixed shell is installed inside the outer casing. The wire feeding device includes a transmission wheel and a motor. The motor and the transmission wheel are mounted on the fixed shell. The motor drives the transmission wheel to rotate. An annular groove is formed on the transmission wheel, and the annular groove drives the welding wire to move.

[0017] Through the above technical solution, the extrusion device extrudes the welding wire, making the welding wire better contact with the annular groove and making the movement of the welding wire more stable.

[0018] Furthermore, the extrusion device includes a rotating plate, an extrusion wheel, and a locking member. The rotating plate is rotatably connected to the fixed shell, and the locking member is used to lock the rotating plate. The extrusion wheel is rotatably connected to the rotating plate. When the locking member locks the rotating plate, the extrusion wheel extrudes the welding wire, and the welding wire presses against the annular groove.

[0019] Through the above technical solution, the extrusion wheel extrudes the welding wire, and when the welding wire is in motion, the welding wire can drive the extrusion wheel to rotate, making the welding wire slide more smoothly.

[0020] Furthermore, the outer casing includes a housing and a mounting housing, the housing and the mounting housing being detachably connected. The mounting housing has a clearance opening. The locking member includes a rotating rod and a limiting block. The rotating rod is connected to the limiting block and is rotatably connected to the fixed housing. When the locking member locks the rotating plate, the limiting block abuts against the rotating plate. When the mounting housing is installed with the housing, the limiting block passes through the clearance opening, and the mounting housing limits the limiting block.

[0021] With the above technical solution, when the locking component is unlocked, the rotating plate is rotated to facilitate the installation of the welding wire, so that the welding wire contacts the annular groove. The mounting shell can prevent the locking component from contacting the locking of the rotating plate. Attached Figure Description

[0044] See Figure 10 Along the trajectory path of the second recessed channel 903 and away from the first recessed channel 902, the width of the second recessed channel 903 gradually narrows.

[0045] The greater the angle at which the protrusion 10 moves on the second recessed channel 903, the better the connection between the welding rod 7 or the welding tube 3 and the mounting block 9.

[0046] See Figure 3 , Figure 9 The outer casing 1 has a mounting hole 101, and the mounting block 9 has a mounting part 904. The mounting part 904 is mounted on the mounting hole 101, and the mounting hole 101 is adapted to the mounting part 904.
