[0053] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0054] The following detailed description of the technical solutions of the embodiments of the present application is given with reference to the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0055] Reference Figures 1 to 3 As shown, a welding tool provided in an embodiment of the present application includes: a base 100, on which two support bases 110 are provided; a box body 200, which is erected between the two support bases 110 and is rotatably connected to the support bases 110; a positioning mechanism 300, which is provided on the box body 200, and the positioning mechanism 300 is used to fix the workpiece to be welded.

[0056] In a specific implementation, the parts to be welded can be titanium alloy, or alloys or metals of other materials; the box 200 has a cavity for accommodating the parts to be welded, wherein the size of the cavity can be designed according to the outer contour of the parts to be welded; the number of positioning mechanisms 300 is set to multiple, and the multiple positioning mechanisms 300 are evenly distributed on each side of the box 200 to limit the parts to be welded in the cavity from different directions, so as to avoid the parts to be welded from shaking left and right during the welding process, affecting the welding effect, and improving the stability of the parts to be welded during welding.

[0057] The angle adjustment mechanism 400 is configured to fix the box body 200 on the support base 110 after the box body 200 rotates a preset angle relative to the support base 110, so that the box body 200 remains in the current position.

[0058] In a specific implementation, the angle adjustment mechanism 400 is provided on both support bases 110. Of course, the angle adjustment mechanism 400 can also be selectively provided on either of the two support bases 110, and will not be described in detail here.

[0059] Before the welding operation, the workpiece to be welded is fixed on the box body 200 by the positioning mechanism 300 so that the workpiece to be welded and the box body 200 form a whole, and ensure that the first welding surface of the workpiece to be welded is vertically facing upwards so that the welding operation can be performed on the first welding surface; when the welding of the first welding surface is completed and it is necessary to weld the second welding surface of the workpiece to be welded, it is only necessary to rotate the box body 200, and after the box body 200 is rotated to a preset angle, that is, after the second welding surface of the workpiece to be welded is vertically facing upwards, the angle adjustment mechanism 400 is used to fix the box body 200 on the support seat 110 so that the box body 200 maintains the current tilted state, which is convenient for the staff to complete the welding operation on the second welding surface.

[0060] Compared with the welding tool in the prior art, the welding tool provided in the present application can flip the workpiece to be welded according to the orientation of the welding surface, thereby facilitating the welding operation of the workers.

[0061] Reference Figures 1 to 3 、 Figure 5 As shown, in some embodiments, a plurality of snap-in holes 211 are provided on the side of the box body 200, and the plurality of snap-in holes 211 are spaced apart on the same radial circumference around the rotation axis of the box body 200 with the rotation axis of the box body 200 as the center; the angle adjustment mechanism 400 includes a mounting hole 410 and a snap-in component 420, the mounting hole 410 passes through the support base 110, and the snap-in component 420 is passed through the mounting hole 410 and connected to one of the snap-in holes 211 to fix the box body 200 on the support base 110.

[0062] In the above embodiment, a plurality of clamping holes 211 are provided so that the clamping member 420 can fix the box body 200 in different tilting states to meet the welding requirements of the welded parts with different orientations of the welding surface.

[0063] Specifically, when the box body 200 rotates a preset angle relative to the support base 110, i.e., the welding surface of the welding piece is vertically upward, one of the clamping holes 211 corresponds to the mounting hole 410, the clamping hole 211 and the mounting hole 410 are communicated to form a clamping channel, at this time, only the clamping piece 420 needs to pass through the mounting hole 410, and the end of the clamping piece 420 is connected with the clamping hole 211, and the clamping piece 420 can keep the current inclined state of the box body 200 by the strength of the clamping piece 420 itself, which is convenient for subsequent welding operation of the worker.

[0064] Further, in some embodiments, the side surface of the box body 200 is provided with an arc-shaped groove 210 with the box body 200 rotation axis as the center, and the clamping holes 211 are arranged in the arc-shaped groove 210.

[0065] Since the welding piece has multiple welding surfaces with different orientations, the worker needs to frequently pull out or insert the clamping piece 420 to adjust the inclined state of the box body 200 during the welding process, but frequent pulling out or inserting the clamping piece 420 not only easily causes the clamping piece 420 to be lost, but also causes the surface of the clamping piece 420 to be rough when the clamping piece 420 moves relative to the mounting hole 410, which makes the clamping piece 420 not smooth enough during subsequent pulling and inserting operation, affecting the welding efficiency.

[0066] Therefore, in the above embodiment, the arc-shaped groove 210 is arranged, which means that a certain gap is reserved between the clamping hole 211 and the mounting hole 410, so that the clamping piece 420 does not need to be completely pulled out when adjusting the inclined state of the box body 200, which is convenient for subsequent welding operation of the worker.

[0067] Referring to Figure 1 In some embodiments, the support base 110 is provided with an arc-shaped scale plate 111, which extends around the circumference of the box body 200 rotation axis with the box body 200 rotation axis as the center; the arc-shaped scale plate 111 has scales 111a, which are arranged at intervals along the extension direction of the arc-shaped scale plate 111, and the scales 111a correspond to the clamping holes 211 one by one.

[0068] In a specific implementation, the arc-shaped scale plate 111 is provided with a plurality of scales 111a spaced along the extension direction of the arc-shaped scale plate 111, and each scale 111a is used to correspond to a different inclination state of the box body 200; when the box body 200 is rotated by a preset angle relative to the support seat 110, the worker records the scale 111a corresponding to the current inclination state of the box body 200, so as to avoid repeated operation when the box body 200 is adjusted subsequently, and affect the welding efficiency. Of course, the density of the scales 111a on the arc-shaped scale plate 111 can be adjusted according to the number of welding surfaces on the to-be-welded piece. For example, when welding the to-be-welded piece with fewer welding surfaces, the arc-shaped scale plate 111 with smaller density of scales 111a is selected, and vice versa when welding the to-be-welded piece with more welding surfaces. Here, no further description is given.

[0069] Referring to FIGS. 1, 2 and 3, Figure 1 and Figure 2 In some embodiments, the positioning mechanism 300 includes two oppositely arranged connecting pieces 310, and the box body 200 is rotationally connected with the support seat 110 through the connecting pieces 310; each connecting piece 310 is movable relative to the box body 200 to jointly clamp the to-be-welded piece.

[0070] Different to-be-welded pieces have different shapes. In the above embodiment, the connecting piece 310 is arranged to be movable relative to the box body 200 to meet the fixing requirements of to-be-welded pieces of different shapes.

[0071] In a specific implementation, the number of connecting pieces 310 is four, and each connecting piece 310 is uniformly distributed on the box body 200 in different directions to limit the to-be-welded piece from different directions, so as to avoid the to-be-welded piece from shaking left and right during welding, affecting the welding effect, and ensure the stability of the to-be-welded piece during welding. Of course, the number of connecting pieces 310 can be three, five or other numbers, and no further description is given here.

[0072] Further, referring to FIGS. 1, 2 and 3, Figures 1 to 3 In some embodiments, the box body 200 is provided with a connecting hole 220, and the connecting hole 220 is a threaded hole; the connecting piece 310 has a threaded section matched with the connecting hole 220, the connecting piece 310 is arranged in the connecting hole 220, and the connecting piece 310 is threadedly connected with the box body 200.

[0073] In a specific implementation, the connection hole 220 is configured as a threaded hole, and the connector 310 is provided with a threaded section adapted to the connection hole 220. The connector 310 and the connection hole 220 are connected by a thread, which not only facilitates the assembly between the connector 310 and the box body 200, but also makes the movement distance of the connector 310 easier to control, avoiding damage to the surface of the welded parts when fixing the welded parts. Of course, the assembly between the connector 310 and the box body 200 can also be replaced by other connection structures, such as sliders and slots, to ensure that the connector 310 can move relative to the box body 200. These will not be described in detail here.

[0074] Reference Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the positioning mechanism 300 further includes a pressing block 320 ; the pressing block 320 is installed on each connecting member 310 , and each connecting member 310 drives the pressing block 320 to move relative to the box body 200 to clamp the parts to be welded together through the pressing block 320 .

[0075] Here, a pressure block 320 is provided at the end of the connector 310. The connector 310 abuts against the surface of the workpiece to be welded via the pressure block 320, thereby increasing the contact area between the connector 310 and the workpiece to be welded. This improves the fit strength between the connector 310 and the workpiece to be welded while preventing the connector 310 from exerting force on the workpiece to be welded, thereby preventing the surface of the workpiece to be welded from being damaged. Specifically, the pressure block 320 is configured as a square as in the above embodiment, but can also be configured as a circle or other shape that adapts to the outer contour of the workpiece to be welded, which will not be described in detail here.

[0076] Meanwhile, the pressing block 320 may be made of a material with good thermal conductivity, such as copper, aluminum, graphite, etc., to conduct the heat generated during the welding process.

[0077] Further, refer to Figure 4 As shown, in some embodiments, the pressing block 320 has multiple air guide channels 321, and the multiple air guide channels 321 are arranged on the edge of the pressing block 320; one end of the air guide channel 321 in the extension direction is used to receive the protective gas required for welding the workpiece to be welded, and the other end of the air guide channel 321 in the extension direction is used to face the workpiece to be welded.

[0078] Some welded parts made of special materials, such as titanium alloy, are susceptible to oxidation reactions when exposed to air, which can lead to the risk of embrittlement during welding. Therefore, in the above embodiment, the pressing block 320 has multiple air channels 321 spaced apart along the edges of the pressing block 320 to prevent interference with the air channels 321 from the welded parts.

[0079] The one end of the air guide channel 321 in the extending direction is used for receiving the shielding gas required for welding the to-be-welded piece, wherein the shielding gas flow is composed of inert gas such as argon, and is delivered into the air guide channel 321 by the fan under pressure; and the other end of the air guide channel 321 in the extending direction is used for being directed towards the to-be-welded piece, so that the to-be-welded piece is wholly covered in the inert gas field, and the contact between the external air and the surface of the to-be-welded piece is prevented, thereby reducing the risk of oxidation reaction of the to-be-welded piece.

[0080] Further, in some embodiments, the air guide channel 321 is obliquely arranged, and the air outlet of the air guide channel 321 is directed towards the welding area on the to-be-welded piece.

[0081] In the specific implementation, the air guide channel 321 is obliquely arranged, so that the air outlet of the air guide channel 321 is directed towards the welding area on the to-be-welded piece, that is, the shielding gas flow output by the fan can be directly blown to the welding area on the to-be-welded piece through the air guide channel 321, thereby optimizing the air isolation effect of the welding area during welding.

[0082] Referring to Figure 1 and Figure 2 In some embodiments, the limiting frame 500 is further included, which is arranged on the box body 200 in a detachable manner, and is used for limiting the to-be-welded piece on the box body 200.

[0083] When the inclination state of the box body is adjusted, the limiting frame 500 can further limit the to-be-welded piece, so as to prevent the to-be-welded piece from sliding off the box body 200, thereby improving the stability of the to-be-welded piece during welding.

[0084] It should be understood that the various forms of flow shown above can be used to reorder, add or delete steps. For example, the steps described in the embodiments of the present application can be executed in parallel, in sequence or in different orders, as long as the desired results of the technical solutions disclosed in the embodiments of the present application can be achieved, which are not limited herein.

[0085] The above specific embodiments do not constitute a limitation on the protection scope of the embodiments of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent replacement and improvement made within the principles of the embodiments of the present application shall be included in the protection scope of the embodiments of the present application.
