DETAILED DESCRIPTION

[0036] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0038] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] A preferred embodiment of the present application is as follows Figures 1 to 7 As shown, an automatic argon arc welding device includes a two-dimensional moving mechanism 1, a welding fixture 2, a welding assembly 3 and a workpiece placement moving mechanism 4;

[0041] The welding fixture 2 and the welding assembly 3 are respectively installed at the output ends of the two-dimensional moving mechanism 1, and the welding end of the welding assembly 3 is directly opposite to the clamping center a of the welding fixture 2, and the workpiece placement moving mechanism is located below the two-dimensional moving mechanism 1;

[0042] The two-dimensional moving mechanism 1 is used to drive the welding fixture 2 and the welding assembly 3 to move synchronously in the X-axis and Z-axis directions; the workpiece placement moving mechanism 4 is used to place the workpiece and to move the workpiece in the Y-axis direction;

[0043] The welding fixture 2 is used to clamp the workpiece on the workpiece placement moving mechanism, and is used to automatically center the workpiece to the clamping center a.

[0044] Specifically, when the automatic argon arc welding equipment is processing the workpiece to be processed, the two-dimensional moving mechanism 1 calibrates the position in the X-axis and Z-axis directions to move the welding fixture 2 and the welding assembly 3 to the preset position, and the workpiece placement moving mechanism 4 calibrates the position in the Y-axis direction to move the workpiece to be processed to the preset position, so as to facilitate the processing of the workpiece to be processed, wherein the welding fixture 2 automatically resets to the center after clamping the workpiece to be processed. Compared with the prior art in which the welding fixture 2 and the welding assembly 3 have independent driving mechanisms respectively, the utility model designs the welding fixture 2 and the welding assembly 3 on the same two-dimensional moving mechanism 1, and the welding end of the welding assembly 3 is directly opposite to the clamping center a of the welding fixture 2, and the workpiece placement moving mechanism is located below the two-dimensional moving mechanism 1, so as to realize the synchronous movement of the two, improve the accuracy of the welding point, and solve the problem that after the separate independent driving, the process needs to be increased manually or automatically to realign, and the process is cumbersome and costly. The two-dimensional moving mechanism 1 and the workpiece placement moving mechanism use PLC as the control core.

[0045] In an optional embodiment, the welding fixture 2 includes a mounting plate 21, a reset centering component 22 and a clamping component 23;

[0046] The resetting and centering component 22 and the clamping component 23 are arranged on the mounting plate 21 in a vertical direction relative to each other. The clamping component 23 is movably mounted on the mounting plate 21 in the X-axis direction. A first convex portion 236 is provided at the top center of the clamping component 23. The clamping component 23 is used to clamp the workpiece to be processed.

[0047] The reset centering component 22 includes a fixing portion 24 and two elastic sub-components 25. The fixing portion 24 is fixedly mounted on the mounting plate 21. The fixing portion 24 is provided with two left-right symmetrical second protrusions 241 with the first protrusion 236 as the symmetric center. One end of one elastic sub-component 25 is connected to one second protrusion 241, and one end of another elastic sub-component 25 is connected to another second protrusion 241. The other ends of the two elastic sub-components 25 are both connected to the first protrusion 236.

[0048] The two elastic sub-assemblies 25 provide elastic force to pull the clamping assembly 23 back to its original position.

[0049] Specifically, when the welding fixture 2 clamps the workpiece to be processed, position displacement may occur. The welding fixture 2 relatively arranges a reset centering component 22 and a clamping component 23 on the upper and lower parts of the mounting plate 21. A first protrusion 236 is provided at the top center of the clamping component 23, and second protrusions 241 are provided on both sides of the fixing portion 24 with the first protrusion 236 as the center of symmetry. One end of an elastic subcomponent 25 is connected to one of the second protrusions 241, and one end of another elastic subcomponent 25 is connected to another second protrusion 241. The other ends of the two elastic subcomponents 25 are connected to the first protrusion 236, and the clamping component 23 moves parallel to the X-axis on the mounting plate 21. Therefore, when the clamping component 23 is displaced, the two horizontally symmetrically arranged elastic subcomponents 25 in the reset centering component 22 can provide elastic force to reset the clamping component 23 to the center and return to the preset position, so as to solve the problem that the welding fixture 2 is displaced, manual adjustment and correction are required, and production efficiency is reduced. The elastic subassembly 25 is a tension spring, and two ends of the tension spring are respectively sleeved on the first protrusion 236 and the second protrusion 241 , and the first protrusion 236 and the second protrusion 241 are both screws.

[0052] Specifically, high temperature is generated during welding operation, which will cause the temperature of the clamping part 231 to rise. By setting the cooling channel 232, cooling water enters from the water inlet 234, flows through the cooling channel 232 and the water outlet 235 in sequence, and the temperature of the clamping part 231 is reduced and maintained by the circulating cooling water.

[0055] Specifically, the bending portion of the flexible bending tube 6 is set according to the range of motion of the first clamping portion 2311 and the second clamping portion 2312 to ensure that the flexible bending tube 6 can bend when the first clamping portion 2311 and the second clamping portion 2312 are close to or away from each other, so as to avoid the flexible bending tube 6 from being subjected to excessive tensile or compressive stress. In addition, after the cooling water enters from the first water inlet 2341, it flows through the cooling channel 232, the first water outlet 2351, the flexible bending tube 6, the second water inlet 2342, the cooling channel 232 and the second water outlet 2352 in sequence.
