Description

Technical Field

[0001] This utility model belongs to the field of welding technology, specifically relating to a gas shielded welding device. Background Technology

[0002] Gas shielded welding, a common shielded gas welding process, typically uses inert gases (such as argon) or carbon dioxide to protect the welding area and prevent the metal from oxidizing with oxygen in the air.

[0003] In traditional gas-shielded welding equipment, long, strip-shaped accessories such as welding torch cables and wire feed hoses are prone to tangling during the welding process due to movement or rotation, leading to welding interruptions, equipment wear, and even safety hazards. Furthermore, the anti-tangling devices used in existing gas-shielded welding equipment have complex structures and fixed adjustments, making them difficult to adapt to different welding angles and positions. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a gas shielded welding equipment that can avoid the entanglement of long strip-shaped accessories and facilitate welding operations, in view of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a gas shielded welding equipment, comprising:

[0006] support;

[0007] Welding torch;

[0008] A long, strip-shaped accessory connected to a welding torch, wherein the long, strip-shaped accessory is a wire feeding hose and / or cable;

[0009] Its characteristic is that it also includes:

[0010] A vertically mounted rotating cylinder is positioned above the welding torch, and its interior is hollow, forming a through-channel for the long strip-shaped accessory to pass through. The rotating cylinder can rotate around its own central axis under the drive of the drive mechanism.

[0011] The connecting frame has its upper part fixed to the rotating drum and can rotate with the rotating drum, and its lower part is provided with a support for supporting the welding gun; the welding gun is set with the gun head facing down and located below the support, and under the action of external force, the gun head can rotate relative to the support about its own vertically extending central axis.

[0012] The combination of the rotating drum and the connecting frame allows the drum to be driven to rotate as needed during the welding process, thereby causing the welding torch to move around the central axis of the drum. During this movement, the torch head can rotate around its own central axis, thus preventing the long strip-shaped accessories connected to the welding torch from getting tangled or twisted, and facilitating the welding operation.

[0013] Preferably, the support portion is a first bearing, comprising:

[0014] The inner ring has a central hole for the torch head to pass through, and the inner ring is fixed to the welding torch;

[0015] An outer ring is circumferentially disposed outside the inner ring and is circumferentially rotatable relative to the inner ring; the outer ring is connected to the connecting frame.

[0016] Preferably, the central axis of the gun head is offset from the central axis of the rotating drum.

[0017] Furthermore, the connecting frame includes:

[0018] The vertically installed pole has the aforementioned support portion at its lower end;

[0019] A horizontal bar is arranged intersecting and connected to the upper end of the upright, and the end of the horizontal bar is fixed to the rotating cylinder.

[0020] In the above solution, preferably, the support includes:

[0021] A crossbeam, the first end of which is used to mount the rotating drum;

[0022] The column is connected at its upper part to the second end of the crossbeam;

[0023] The base provides support for the column.

[0024] Furthermore, the first end of the crossbeam is provided with a horizontal mounting plate, which has a through hole that penetrates the plate thickness to allow the elongated fitting to pass through;

[0025] The upper end of the rotating drum is located on the lower side of the mounting plate corresponding to the through hole, and is rotatably connected to the mounting plate around the central axis.

[0026] Furthermore, the upper end of the rotating drum is connected to the mounting plate via a second bearing, which includes:

[0027] A lower ring arranged and connected to the upper end of the rotating drum along the same axis;

[0028] An upper ring is located above the lower ring and is arranged coaxially with the lower ring. The upper ring is connected to the mounting plate and can rotate circumferentially relative to the lower ring.

[0029] Finally, the drive mechanism is a motor mounted on the mounting plate. The motor shaft extends downward and is connected to a small gear. The upper end of the rotating drum is provided with a large gear arranged coaxially, which meshes with the small gear. Thus, the small gear can drive the large gear and the rotating drum to rotate.

[0030] Compared with the prior art, the advantages of this utility model are as follows: through the cooperation of the rotating drum and the connecting frame, the rotating drum can be driven to rotate according to the needs during the welding process, thereby driving the welding torch to move around the central axis of the rotating drum. During the movement, the torch head can rotate relative to the support part (i.e. relative to the connecting frame and the rotating drum) around its own central axis. Therefore, there is no relative rotation between the welding torch and the long strip-shaped accessory, thereby avoiding the phenomenon of entanglement and twisting of the long strip-shaped accessory connected to the welding torch, and facilitating the welding operation.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] like Figures 1-5 As shown, this is a preferred embodiment of a gas shielded welding device of the present invention. The gas shielded welding device includes a support 1, a welding torch 2, a long strip-shaped accessory 3, a rotating drum 4, a drive mechanism 5, and a connecting frame 6.

[0038] The welding torch 2 is existing technology, and it is connected to a long strip-shaped accessory 3, which is a wire feeding hose and / or cable.

[0039] The support frame 1 includes a crossbeam 11, a column 12, and a base 13. The first end of the crossbeam 11 is a free end, and the second end is connected to the upper part of the column 12. The bottom of the column 12 is supported on the base 13. In this embodiment, both the crossbeam 11 and the column can be designed with a telescopic structure to be adjusted according to the needs of welding. At the same time, the first end of the crossbeam 11 is provided with a horizontal mounting plate 14, and the mounting plate 14 has a through hole 140 for the long strip-shaped accessory 3 to pass through.

[0040] The rotating drum 4 is vertically positioned below the mounting plate 14 and above the welding torch 2. The interior of the rotating drum 4 is hollow, forming a through-hole 40 for the long strip-shaped accessory 3 to pass through. Driven by the driving mechanism 5, the rotating drum 4 can rotate around its central axis 41. In this embodiment, the upper end of the rotating drum 4 is arranged corresponding to the through hole 140 of the mounting plate 14, and the upper end of the rotating drum 4 is connected to the mounting plate 14 via a second bearing 7. This second bearing 7 includes: a lower ring 71 coaxially arranged and connected to the upper end of the rotating drum 4; and an upper ring 72 located above the lower ring 71 and coaxially arranged with it. The upper ring 72 is connected to the mounting plate 14 and can rotate circumferentially relative to the lower ring 71, thus allowing the rotating drum 4 to be circumferentially rotatably mounted on the lower side of the mounting plate 14. To ensure smooth rotation of the upper ring relative to the lower ring, ball bearings, such as those found in existing thrust bearings, can be provided between the upper and lower rings. See details... Figure 4 .

[0041] The drive mechanism 5 is a motor mounted on the mounting plate 14. The motor shaft extends downward to the lower side of the mounting plate 14 and is connected to a small gear 51. The upper end of the rotating drum 4 is provided with a large gear 52 arranged coaxially, and the large gear 52 meshes with the small gear 51. Thus, the small gear 51 can drive the large gear 52 and the rotating drum 4 to rotate around the central axis 41 under the drive of the motor.

[0042] The aforementioned connecting frame 6 includes a vertically arranged upright 6a and a horizontal bar 6b ​​that is intersected with the upper end of the upright 6a and connected by a connecting block. The end of the horizontal bar 6b ​​is fixed to the rotating drum 4 so that it can rotate with the rotating drum 4. The lower end of the upright 6a is provided with a support part 60 for supporting the welding torch 2. The welding torch 2 is arranged with the torch head 20 facing downward and located below the support part 60. Under the action of external force, the torch head 20 can rotate relative to the support part 60 around its own vertically extending central axis 21. The central axis 21 is offset from the central axis 41 of the rotating drum 4. Specifically, as shown... Figure 5 As shown, the support portion 60 in this embodiment is a first bearing, including an inner ring 61 and an outer ring 62. The inner ring 61 has a through hole in the center for the welding torch 20 to pass through, and is connected to the welding torch 2. The outer ring 62 is circumferentially disposed outside the inner ring 61 and can rotate circumferentially relative to the inner ring 61. The outer ring 62 is connected to the connecting frame 6, so that the welding torch can be supported on the support portion 60 and can rotate freely circumferentially. In order to make the outer ring 62 rotate smoothly relative to the inner ring 61, balls, such as existing deep groove ball bearings, can be provided between the outer ring and the inner ring.

[0043] During the welding process, the rotating drum 4 can be driven to rotate as needed, thereby causing the welding torch 2 to move around the central axis of the rotating drum. During the movement, since the torch head of the welding torch 2 is supported on the support part through the first bearing, it can rotate relative to the support part around the central axis of the torch head itself. Therefore, once the long strip-shaped accessory 3 starts to entangle or twist due to the movement of the welding torch 2 around the central axis 41 of the rotating drum, the reaction force will cause the welding torch 2 to rotate relative to the support part around the central axis 21 of the torch head itself, so that there will be no relative rotation between the welding torch 2 and the long strip-shaped accessory 3. That is, the welding torch and the long strip-shaped accessory can rotate synchronously with the rotating drum, thereby avoiding the phenomenon of entanglement or twisting of the long strip-shaped accessory connected to the welding torch, and facilitating the welding operation.

[0044] In the specification and claims of this utility model, terms indicating direction, such as "upper," "lower," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0045] The term "vertical" is also used in the specification and claims of this utility model, meaning basically along the up and down direction, and is not limited to just the vertical direction, but can also be slightly deviated from the vertical direction.
