[0006] The positioning structure is provided with a plurality of air outlet holes at one end near the welding point. The air outlet holes are arranged circumferentially along the positioning structure and are connected to the gap, and there is a height difference between the air outlet holes and the welding point. When gas is filled into the air outlet holes, the gas flows from the air outlet holes to the side wall of the oil cup, and then flows from the side wall to the welding point.

[0007] In the above-mentioned oil cup welding tool, the air outlet is inclined toward directly below the welding point to form the height difference, and after the inclination, the angle between the axis of the air outlet and the horizontal line is 5° to 6°.

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] like Figures 1 to 5 As shown, an oil cup welding tool includes:

[0026] The support frame 100 is provided with a positioning structure 200 and a fixing assembly. The positioning structure 200 and the fixing assembly cooperate to position and fix the end of the oil cup, and a gap is provided between the welding point of the positioning structure 200 and the oil cup;

[0027] The positioning structure 200 is provided with a plurality of air outlet holes 210 at one end near the weld point. These air outlet holes 210 are arranged circumferentially around the positioning structure 200 and communicate with the gap. There is a height difference between the air outlet holes 210 and the weld point. When gas is injected into the air outlet holes 210, the gas flows from the air outlet holes 210 to the sidewalls of the oil cup, and then from the sidewalls to the weld point. This design allows operators to quickly cool the oil cup during welding by injecting nitrogen into the air outlet holes 210, preventing the oil cup from yellowing or blackening during welding. This eliminates the need for subsequent grinding, polishing, and wire drawing of the weld point, effectively improving oil cup production efficiency and reducing labor costs.

[0028] Specifically, if Figures 1 to 5 As shown, in this embodiment, the support frame 100 is in an inverted T-shape, serving as a support structure when the oil cup is fixed, and includes a first support plate 110 and a second support plate 120 vertically connected to each other, wherein the first support plate 110 is arranged horizontally, and the second support plate 120 is vertically arranged in the middle position of the first support plate 110 to form a structurally stable support frame 100.

[0029] It is worth noting that when the oil cup is fixed on the positioning structure 200 , the end of the oil cup away from the fixing assembly abuts against the first support plate 110 , thereby ensuring the subsequent fixing effect of the oil cup.

[0030] In this embodiment, the support frame 100 is provided with a positioning structure 200 and a fixing component, wherein the positioning structure 200 is used to locate the welding position of the oil cup, and the fixing component is used to ensure the stability of the oil cup during welding. The two cooperate to position and fix the end of the oil cup to ensure the accuracy and stability of the oil cup welding.

[0031] In this embodiment, the positioning structure 200 is provided on the vertically arranged second support plate 120, is closely connected to the second support plate 120, and extends along the length direction of the second support plate 120, and is used to cooperate with the fixing component to clamp the oil cup to ensure the stability of the oil cup during welding.

[0032] In this embodiment, the positioning structure 200 includes a first positioning surface 201, a second positioning surface 202, and a third positioning surface 203, which are connected in sequence, and a fourth positioning surface 204, which is perpendicularly connected to the ends of the first positioning surface 201, the second positioning surface 202, and the third positioning surface 203. The first positioning surface 201, the second positioning surface 202, the third positioning surface 203, and the fourth positioning surface 204 cooperate with the second support plate 120 to form a trapezoidal block that matches the shape of the oil cup. This design allows the oil cup to better fit on the positioning structure 200 during welding, effectively improving the accuracy and stability of the oil cup's positioning.

[0033] It should be noted that when the oil cup is fixed on the positioning structure 200, there is a gap between the first positioning surface 201, the second positioning surface 202, the third positioning surface 203 and the welding point of the oil cup. The gap allows gas to flow to the welding point so that the cooling operation can be carried out smoothly during the welding process.

[0034] In this embodiment, the positioning structure 200 is provided with a plurality of air outlet holes 210 near the welding point. These air outlet holes 210 are arranged in a circular pattern around the positioning structure 200, and are located on the first positioning surface 201, the second positioning surface 202, the third positioning surface 203, and their connecting edges. This design allows the weld seam to be rapidly cooled by injecting nitrogen into the air outlet holes 210 during welding, thus preventing the oil cup from yellowing or blackening after welding.

[0035] In this embodiment, there's a height difference between the air outlet 210 and the weld point. Specifically, the air outlet 210 is tilted directly below the weld point, with the angle between the axis of the air outlet 210 and the horizontal being 5° to 6°. This ensures that when gas is introduced into the air outlet 210, it first flows toward the sidewalls of the oil cup, then flows upward toward the weld point, cooling the weld. This design ensures timely cooling of the weld while preventing nitrogen from directly impacting the weld and causing a cold weld, effectively maintaining a good weld quality for the oil cup.

[0036] In this embodiment, the axes of two adjacent air outlet holes 210 form an angle between them, and this angle is greater than 5° and less than 90°. This design achieves more uniform gas distribution and avoids overlapping coverage areas of two adjacent air outlet holes 210. This reduces the number of air outlet holes 210 while maintaining a cooling effect, effectively ensuring the strength of the positioning structure 200 and improving the processing efficiency of the air outlet holes 210.

[0037] In this embodiment, the positioning structure 200 further includes a diverter 220 and a gas supply channel 230. The diverter 220 is circular and is connected to a plurality of gas outlets 210, serving as a confluence point before gas dispersion. One end of the gas supply channel 230 is connected to the diverter 220, and the other end passes through the second support plate 120 to connect to the outside. The gas supply channel 230 is also curved. On the one hand, this design improves the convenience of accessing the nitrogen device by extending the gas supply channel 230 to the side of the second support plate 120 facing away from the positioning structure 200. On the other hand, the curved design of the gas supply channel 230 reduces resistance during gas transmission, ensuring that the gas can quickly and efficiently reach the diverter 220 and flow out through the gas outlets 210, effectively ensuring smooth gas flow.

[0038] Preferably, in this embodiment, a sealing joint 500 is further provided at a position opposite to the air inlet of the air supply channel 230. The sealing joint 500 not only enables a detachable connection between the air supply channel 230 and the nitrogen device, but also ensures the airtightness of the connection.

[0039] In this embodiment, two sets of positioning structures 200 and fixing components are provided, arranged in a left-right configuration on the second support plate 120. The two sets of positioning structures 200 are arranged as mirror images, meaning that the shapes of the two sets of positioning structures 200 face opposite directions. This design allows the welding tool to weld oil cups with different orientations and improves welding efficiency.

[0040] To ensure the stability of the oil cup during welding, in this embodiment, a fixing assembly cooperates with the positioning structure 200 to clamp the oil cup. The fixing assembly comprises a first fixing structure 300 and a second fixing structure 400, both mounted on the second support plate 120. The first fixing structure 300 cooperates with the positioning structure 200 to limit movement of the oil cup end in the X- and Y-axis directions, while the second fixing structure 400 cooperates with the positioning structure 200 to limit movement of the oil cup end in the Z-axis direction. This design allows the oil cup to be clamped between the positioning structure 200 and the fixing assembly, securing it in all three directions: X, Y, and Z. This ensures absolute stability during welding and improves welding accuracy.

[0041] In this embodiment, two sets of first fixing structures 300 are provided, one on each side of the positioning structure 200. Each set of first fixing structures 300 includes a first clamping portion 330 rotatably mounted on the second support plate 120. The first clamping portion 330 is L-shaped and has a first rotational position and a second rotational position. When the two sets of first clamping portions 330 are in the first rotational position, the first clamping portions 330 abut against the outer walls of the oil cup on the first positioning surface 201, the second positioning surface 202, and the third positioning surface 203, thereby cooperating with the positioning structure 200 to limit the oil cup in the X- and Y-axis directions. When the two sets of first clamping portions 330 are in the second rotational position, the first clamping portions 330 separate from the outer walls of the oil cup, releasing the restriction on the oil cup's movement. This design not only improves the ease of loading and unloading the oil cup, but also simplifies the overall structure of the fixing assembly and reduces the manufacturing cost of the oil cup welding tooling.

[0042] Preferably, in this embodiment, the first fixing structure 300 includes a first fixing frame 310 detachably mounted on the second support plate 120, and a rotating member 320 rotatably mounted on the first fixing frame 310. The rotating member 320 includes a first handle 321 and a first adjustment arm 322 arranged in a cross pattern. The first handle 321 is rotatably connected to the first fixing frame 310 and is connected to the first adjustment arm 322 via a connecting arm 323. One end of the first adjustment arm 322 is rotatably connected to the first fixing frame 310, and the other end is fixedly connected to the first clamping portion 330. When an operator pulls the first handle 321 laterally, the first adjustment arm 322 causes the first clamping portion 330 to rotate about the first fixing frame 310 toward or away from the positioning structure 200. This design effectively improves the efficiency and convenience of oil cup assembly and disassembly, while also enhancing the ease of assembly and maintenance of the first fixing structure 300.

[0043] In this embodiment, the second fixing structure 400 is positioned above the positioning structure 200 and includes a second clamping portion 430 movably mounted on the second support plate 120. The second clamping portion 430 has a first and a second movable position. When the second clamping portion 430 is in the first movable position, it abuts against the outer wall of the oil cup on the fourth positioning tube surface, thereby cooperating with the positioning structure 200 to limit the oil cup in the Z-axis direction. When the second clamping portion 430 is in the second movable position, the second clamping portion 430 separates from the outer wall of the oil cup, releasing the restriction on the oil cup's movement. This design not only improves the ease of attaching and detaching the oil cup, but also simplifies the overall structure of the fixing assembly and reduces the manufacturing cost of the oil cup welding tooling.

[0044] Preferably, in this embodiment, the second fixed structure 400 includes a second fixed frame 410 detachably provided on the second support plate 120, and a linkage structure 420 rotatably provided on the second fixed frame 410, and the second fixed frame 410 has a groove portion 411, and the linkage structure 420 includes a second handle 421 and a second adjustment arm 422, and the second handle 421 is rotatably connected to the second fixed frame 410 and the second adjustment arm 422, respectively, and one end of the second adjustment arm 422 is rotatably connected to the second fixed frame 410, and the other end is detachably connected to the second clamping portion 430. When the operator pulls the second handle 421 vertically upward, the connection end of the second handle 421 and the second adjustment arm 422 moves into the groove 411. The second handle 421 and the second adjustment arm 422 contract in a V-shape, driving the second clamping portion 430 to rise obliquely, separating from the outer wall of the oil cup. When the operator presses the second handle 421 vertically downward, the connection end of the second handle 421 and the second adjustment arm 422 moves out of the groove 411. The second handle 421 and the second adjustment arm 422 expand in a straight line, driving the second clamping portion 430 to move obliquely downward until it contacts the outer wall of the oil cup. This design effectively improves the efficiency and convenience of loading and unloading the oil cup, while also enhancing the ease of assembly, disassembly, and maintenance of the second fixing structure 400.
