[0038] Embodiment 1

[0039] As Figure 1 And Figure 2 The utility model provides automatic welding argon filling tool includes: support 1, welding head 2, support seat 3, groove 4 and clamping piece (not draw) as shown in the utility model.

[0040] Among them, support 1 and welding head 2 constitute automatic welding device, support 1 can drive welding head 2 along vertical and horizontal movement, specifically, the support 1 has first drive mechanism and second drive mechanism, wherein, first drive mechanism and second drive mechanism can be linear drive module, for example screw motor module.The first drive mechanism is connected with the drive end, is used for driving the drive end along vertical movement.The second drive mechanism is connected with the first drive mechanism, is used for driving the first drive mechanism and drive end along horizontal movement.Thereby welding head 2 can move in two directions, by increasing drive mechanism, also can make welding head 2 move in three perpendicular directions.

[0041] The support seat 3 is located below welding head 2, and has an arc-shaped support surface, which can be a complete surface or a discontinuous surface, and the arc-shaped support surface is used to support the pipe 11 to be welded.In the embodiment, the support seat 3 includes a plurality of rolling elements 31 arranged along the arc, the side surfaces of the plurality of rolling elements 31 are in contact with the side walls of the pipe to be welded, the axes of the rolling elements 31 extend in the horizontal direction and are parallel to each other, and the plurality of rolling elements 31 form a discontinuous arc-shaped support surface.The pipe to be welded can roll relative to the support seat 3, thereby adjusting the position of the weld.

[0042] The groove 4 needs to be sealedly connected with the pipe to be welded, the length direction of the groove 4 is consistent with the length direction of the pipe 11 to be welded, and the length of the groove 4 is greater than or equal to the length of the weld.It should be noted that when the length of the opening of the groove 4 is greater than the length of the weld, part of the opening is exposed, and needs to be covered and sealed with aluminum foil to improve the sealing performance.

[0043] The opening surface is an arc surface, which can better abut against the inner wall of the pipe 11 to be welded and form a seal. In order to achieve a better sealing effect, elastic rubber sealing strips are arranged on the four sides of the opening.

[0044] The side wall of the groove body 4 is provided with an inflation joint 41 communicating between the inside and outside thereof. Preferably, the inflation joint 41 is arranged on the front end surface of the groove body 4, so as to facilitate connection with the gas source and avoid interference by the pipe to be welded.

[0045] The groove body 4 is provided with four ear plates 10, which are respectively arranged on the left and right sides of the front and rear ends of the groove body 4. The clamping member is used to clamp the ear plates 10 and the pipe to be welded after the opening completely covers the weld of the pipe to be welded, so that the opening is tightly attached to the inner wall of the pipe to be welded and a seal is formed, thereby reducing gas leakage.

[0046] Before welding, first place the pipe to be welded on the support seat 3, and connect the groove body 4 with the welding area, so that the opening of the groove body 4 completely covers the welding area. After covering is completed, use the clamping member to clamp the ear plates 10 and the pipe to be welded together, so as to fix the groove body 4 on the pipe to be welded. Then, fill argon into the groove body 4 through the joint, and after the argon concentration reaches the welding standard, use the welding head 2 to weld the weld, thereby completing the welding. During the entire welding process of the weld, the argon is located in the groove body 4, which can reduce the demand for argon and effectively save argon resources, and avoid personal injury caused by argon leakage during manual welding.

[0047] The rear end of the groove body 4 is connected with an arc striking plate 5, which prevents welding defects.

[0048] The clamping member is an elastic clamp.

[0049] Example 2

[0050] As shown in Figure 3 The difference from example 1 is that hooks 6 are arranged on the two ear plates 10 located at the rear end of the groove body 4. When installing the groove body 4, the groove body 4 can be first hooked on the pipe to be welded by using the hooks 6, thereby achieving a temporary fixing effect, and then the ear plates 10 and the pipe to be welded are clamped by using the clamping member. This avoids the need for another worker to hold the groove body 4 when clamping the ear plates 10 and the pipe to be welded.

[0051] Example 3

[0052] As shown in Figure 4The difference between the embodiment 1 and the embodiment 2 is that the automatic welding argon filling tool further comprises a transverse bracket for fixing the groove body 4. The transverse bracket comprises a sliding seat 7, a vertical rod 8 and a horizontal rod 9, and the transverse bracket is in a "C" shape. The vertical rod 8 is adjustable in length, the bottom end of the vertical rod 8 is connected with the sliding seat 7, the front end of the horizontal rod 9 is connected with the top end of the vertical rod 8, the groove body 4 is parallel to the horizontal rod 9, and the bottom surface of the groove body 4 is connected with the side wall of the horizontal rod 9.

[0053] After the pipe to be welded is placed on the support seat 3, the sliding seat 7 is moved transversely, the groove body 4 is moved below the weld, and the vertical rod 8 is raised so that the opening of the groove body 4 abuts against the inner wall of the pipe to be welded, and the length of the vertical rod 8 is locked. The clamping member is used to clamp the ear plate 10 and the pipe to be welded. After welding, the clamping member is loosened, the vertical rod 8 is shortened, the groove body 4 is separated from the pipe to be welded, the sliding seat 7 is moved transversely, and the groove body 4 is withdrawn from the pipe to be welded.

[0054] The sliding seat 7 can be slidably connected with the support seat 3.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
