Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding fixtures, and in particular to a welding fixture for air conditioning pipes. Background Technology
[0002] Air conditioning piping is an important component of air conditioners. Air conditioning piping (such as the air collection pipe) includes multiple branch pipes and a main pipe. The branch pipes are welded and fixed to the main pipe, which also includes straight pipe sections and bends that form an angle with the straight pipe sections.
[0003] In related technologies, welding fixtures for air conditioning pipes include a first positioning component, a second positioning component, and a crimping component. The first positioning component includes a first positioning groove and a second positioning groove, with an angle between them consistent with the angle formed by the straight pipe section and the bent section. The straight pipe section and the bent section are respectively installed in the first positioning groove and the second positioning groove to position the main pipe. The second positioning component is positioned above the first positioning component and has multiple third positioning grooves arranged sequentially along the straight pipe section. Multiple branch pipes are engaged in the multiple third positioning grooves, thus making the welding positions of the multiple branch pipes and the main pipe more accurate. However, since the angles between the straight pipe section and the bent section vary for different specifications of air conditioning pipes, the first positioning component in related technologies cannot be adapted to different specifications of air conditioning pipes. Positioning only the straight pipe section is insufficient; during welding, the bent section is easily affected by external forces, causing the entire main pipe to shift, resulting in unreliable positioning. Therefore, improving the reliability of welding fixtures for air conditioning pipes and making them compatible with different specifications of air conditioning pipes has become an urgent problem to be solved.

[0040] The air conditioner has an air conditioning duct 20, such as a gas collection duct. In this embodiment, the air conditioning duct 20 includes multiple branch pipes and a main pipe 21. The branch pipes are welded and fixed to the main pipe 21. The main pipe 21 also includes a straight pipe section 22 and a bent section 23 forming an angle with the straight pipe section 22. In this embodiment, the multiple branch pipes of the air conditioning duct 20 and the main pipe 21 need to be fixed using a welding fixture 10 to ensure accurate welding positions.
[0041] The welding fixture 10 for air conditioning pipe 20 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0042] like Figures 1-9 As shown, the welding fixture 10 for air conditioning pipe 20 in this embodiment of the present invention includes a support 100, a first positioning component 200 and a second positioning component 300.
[0043] A first positioning component 200 is disposed on a support 100. The first positioning component 200 has a first positioning groove 201 configured to accommodate a straight pipe section 22 of the main pipe body 21, allowing the second positioning component 300 to support and position the straight pipe section 22 of the main pipe body 21 via the first positioning groove 201. The first positioning groove 201 is horizontally positioned, meaning its axial direction is horizontal, allowing the straight pipe section 22 of the main pipe body 21 to be placed horizontally within it. One side of the first positioning groove 201 is open; for example, it is open in a horizontal direction perpendicular to its axial direction, allowing the straight pipe section 22 of the main pipe body 21 to be installed horizontally into the first positioning groove 201.
[0044] The second positioning assembly 300 includes a clamping member 310 and a locking member 320. The clamping member 310 is disposed on the support 100 and configured to clamp the bent section 23 of the main pipe body 21, thereby clamping and fixing the bent section 23 of the main pipe body 21. The clamping member 310 can rotate about an axis perpendicular to the axial direction of the first positioning groove 201, that is, when the straight pipe section 22 of the main pipe body 21 is installed in the first positioning groove 201, the clamping member 310 can rotate relative to the straight pipe section 22. In other words, the clamping member 310 can rotate about a vertical axis at the connection position of the straight pipe section 22 and the bent section 23, so that the clamping member 310 can adapt to various air conditioning pipes 20 with different included angles between the straight pipe section 22 and the bent section 23.
[0045] The locking member 320 is configured to restrict the rotation of the clamping member 310. So when the straight pipe section 22 is installed in the first positioning groove 201, and the clamping member 310 is adjusted to a position corresponding to the bent section 23 and clamps the bent section 23, the locking member 320 can lock the clamping member 310 to restrict the rotation of the clamping member 310, thereby enabling the clamping member 310 to provide stable support for the bent section 23 and prevent the main pipe body 21 from shaking.
[0046] Compared with related technologies, the welding fixture 10 for air conditioning pipe 20 in this embodiment includes a first positioning component 200 and a second positioning component 300. The first positioning component 200 is provided with a first positioning groove 201 for supporting and positioning the straight pipe section 22 of the main pipe body 21. The second positioning component 300 includes a clamping member 310 for clamping the bent section 23 of the main pipe body 21, and the clamping member 310 is rotatable about an axis perpendicular to the first positioning groove 201, and a limiting locking member 320 that allows the clamping member 310 to rotate. By clamping the bent section 23 of the main pipe body 21 with the clamping member 310 and locking the clamping member 310 with the locking member 320, the clamping member 310 provides stable support for the bent section 23, preventing the main pipe body 21 from shifting as a whole due to the movement of the bent section 23 by external force, thus improving the positioning reliability of the welding fixture 10 in this embodiment. Furthermore, the clamping member 310 can rotate around an axis perpendicular to the first positioning groove 201, so that the clamping member 310 can adapt to various air conditioning pipes 20 with different included angles between the straight pipe section 22 and the bent section 23. Therefore, the welding fixture 10 of this embodiment can achieve the purpose of adapting to air conditioning pipes 20 of different specifications.
[0047] To make this application easier to understand, the welding fixture 10 for air conditioning pipe 20 of this utility model embodiment is further described below, taking the example that the axial direction of the first positioning groove 201 is consistent with the left and right directions.
[0048] like Figure 1 and Figure 5 As shown, the welding fixture 10 for the air conditioning pipe 20 in this embodiment of the present invention further includes a third positioning component 400, which includes a second positioning member 410 and a vertical plate 414. The second positioning member 410 is disposed above the first positioning member 210. The second positioning member 410 is provided with a plurality of second positioning grooves 411, which are arranged sequentially in the left-right direction. Each second positioning groove 411 is open on the side adjacent to the first positioning member 210, for example, the second positioning groove 411 is open to the front. The second positioning groove 411 is configured to cooperate with the branch pipe body 24, that is, each branch pipe body 24 is placed in the corresponding second positioning groove 411 so that the second positioning groove 411 is positioned accordingly.
[0049] Before welding, the straight pipe section 22 of the main pipe 21 is placed in the first positioning groove 201, so that the straight pipe section 22 is set in the left and right direction. The lower parts of the multiple branch pipes 24 are inserted into the multiple mounting holes pre-set on the straight pipe section 22, and the upper parts of the multiple branch pipes 24 are placed in the multiple second positioning grooves 411, so as to prevent the branch pipes 24 from shaking during welding.
[0050] In some embodiments, the welding fixture 10 for the air conditioning pipe 20 of this utility model further includes a welding torch bracket 500, on which a welding torch is mounted. The welding torch bracket 500 is movably disposed on the support 100 in the left-right direction so that the welding torch can correspond to the connection position between the branch pipe body 24 and the main pipe body 21 in the left-right direction, so as to facilitate welding by the welding torch.
[0051] In some embodiments, the second positioning groove 411 includes a first limiting plane and a second limiting plane disposed opposite to each other in the left-right direction; both the first limiting plane and the second limiting plane are inclined, and the distance between the first limiting plane and the second limiting plane increases in the direction closer to the open side of the second positioning groove 411. For example, if the second positioning groove 411 is open to the front, the distance between the first limiting plane and the second limiting plane gradually increases in the direction from back to front, thereby limiting the branch pipe body 24 by the first limiting plane and the second limiting plane. The structure is simple, and the second positioning groove 411 can be adapted to branch pipe bodies 24 of different diameters, thus further improving the practicality of the welding fixture 10 in this embodiment.
[0052] In other embodiments, the second positioning groove 411 is an arc-shaped groove that conforms to the outer surface of the branch pipe body 24.
[0053] In some embodiments, such as Figure 5 As shown, the second positioning member 410 is vertically and flexibly connected to the upright plate 414, thereby adjusting the height of the second positioning member 410 to adjust its position in the vertical direction for supporting and positioning the branch pipe 24, thus adapting to branch pipes 24 of different lengths.
[0054] Specifically, the second positioning member 410 includes a positioning plate 415 and a connecting plate 416. The connecting plate 416 is connected to the positioning plate 415. Multiple second positioning grooves 411 are disposed on the positioning plate 415. The connecting plate 416 has a first guide groove that extends through it in the vertical direction. A vertical plate 414 passes through the first guide groove so that the second positioning member 410 can move vertically through the first guide groove. The side wall of the connecting plate 416 has through holes that extend through its outer surface and the wall of the first guide groove in sequence. Bolts are inserted into the through holes. By screwing in the bolts, the bolts press the connecting plate 416 and the first guide groove together, thereby fixing the position of the second positioning member 410 in the vertical direction.
[0055] Furthermore, such as Figure 5 As shown, the second positioning member 410 moves in a direction close to or away from the first positioning member 210, that is, the second positioning member 410 can move in the front-back direction. This allows the second positioning member 410 to be adjusted in the front-back direction, thereby adjusting the relative position of the branch pipe body 24 and the straight pipe section 22 of the main pipe body 21 in the front-back direction, thus improving the practicality of the welding fixture 10 in this embodiment.
[0056] Specifically, such as Figure 5 As shown, the connecting plate 416 is provided with a first guide groove extending in the front-back direction, and the positioning plate 415 is provided with a first guide protrusion that cooperates with the first guide groove. The first guide protrusion is movable in the front-back direction.
[0057] In some embodiments, such as Figures 1-3 As shown, the clamping member 310 is vertically adjustable, thereby changing the position of the clamping member 310 in the vertical direction to adjust the position of the clamping member 310 relative to the first positioning groove 201 in the vertical direction. This allows the straight pipe section 22 and the bent section 23 of the main pipe body 21 to be adjusted in the vertical direction, improving practicality and facilitating the clamping member 310 to fix the bent section 23.
[0058] In some embodiments, such as Figure 3 As shown, the second positioning component 300 also includes a support member 330, which is horizontally positioned. A clamping member 310 is vertically mounted on the support member 330. The support member 330 has a second guide groove extending vertically through it. A lifting rod 340 is connected to the lower part of the clamping member 310, and the lower part of the lifting rod 340 is movably positioned within the second guide groove in the vertical direction. The lower part of the lifting rod 340 has external threads, and two fixing nuts are also threaded onto the lower part of the lifting rod 340. These two fixing nuts are located on opposite sides of the support member 330 in the vertical direction, allowing the position of the clamping member 310 to be adjusted by adjusting the position of the lifting rod 340 in the vertical direction.
[0059] Furthermore, such as Figure 2 and Figure 3 As shown, the clamping member 310 is movably disposed in the horizontal direction. This allows the relative position of the clamping member 310 with respect to the first mounting groove in the horizontal direction to be adjustable, thereby improving practicality.
[0060] Specifically, the clamping member 310 is movably disposed on the support member 330 along the extending direction of the support member 330. This allows the position of the clamping member 310 relative to the support member 330 in the extending direction of the support member 330 to be adjustable, improving practicality and facilitating the clamping member 310 in fixing the bent section 23.
[0061] The second guide groove extends along the extension direction of the support member 330, and the lifting rod 340 is movably disposed in the second guide groove along the extension direction of the support member 330. The lifting rod 340 is fixed by pressing two fixing nuts onto the surface of the support member 330.
[0062] In some embodiments, such as Figure 2 and Figure 3 As shown, the support member 330 is rotatably mounted on the support 100 around one end. Thus, by rotatably mounting the support member 330 on the support 100 around one end, the clamping member 310 can rotate around an axis perpendicular to the first positioning groove 201. The structure is simple and easy to manufacture.
[0063] In some embodiments, the locking member 320 is further configured to lock the rotation of the support member 330 relative to the support 100. Specifically, as Figure 2 and Figure 3 As shown, the support part is provided with a through hole 312; the support 100 is provided with a threaded hole, and the locking member 320 is a threaded connector. The threaded connector passes through the through hole 312 and connects with the threaded hole; the threaded connector is configured to allow the support part to rotate about its axial direction, and its head presses the support part onto the support 100 to restrict the rotation of the support member 330.
[0064] In some alternative embodiments, the clamping member 310 is fixedly disposed on the support member 330 so that the clamping member 310 can only rotate by means of the rotation of the support member 330.
[0065] In some alternative embodiments, the clamping member 310 is rotatably disposed on the support member 330, thereby further increasing the degree of freedom of the clamping member 310 so as to facilitate the mounting of the bent section 23 of the main body 21 onto the clamping member 310.
[0066] In some embodiments, such as Figure 2 and Figure 3As shown, the clamping member 310 includes a mounting cylinder portion 311 and a crimping portion 315. The mounting cylinder portion 311 is used to pass through the bent section 23 and is horizontally positioned. A through hole 312 is provided on the peripheral wall of the mounting cylinder portion 311. One end of the crimping portion 315 extends into the mounting cylinder portion 311 through the through hole 312, and one end of the crimping portion 315 is radially movable along the mounting cylinder portion 311. The crimping portion 315 is configured to crimp the bent section 23 of the main pipe 21 into the mounting cylinder portion 311. Therefore, when clamping the bent section 23, the bent section 23 is first inserted into the mounting cylinder portion 311, and then the crimping portion 315 presses the bent section 23 against the inner wall surface 316 of the mounting cylinder portion 311 to achieve clamping. This not only facilitates installation but also has a simple structure and low manufacturing cost. The crimping part 315 can be a bolt, and the through hole 312 is provided with an internal thread so that the crimping part 315 and the through hole 312 are threaded together so that when the crimping part 315 is screwed in, the bent section 23 is pressed against the inner wall surface 316 of the mounting cylinder part 311.
[0067] Furthermore, the crimping portion 315 is installed on the support member 330 so that the mounting cylinder portion 311 is installed on the support member 330 through the crimping portion 315. That is, the crimping portion 315 forms the lifting rod 340 of the above embodiment, which can not only press the bent section 23, but also movably insert the crimping portion 315 into the second guide groove in the vertical direction to realize the lifting and lowering of the mounting cylinder portion 311. Therefore, the redundancy of the structure is further reduced, and the manufacturing cost is lowered.
[0068] In some embodiments, such as Figure 3 As shown, the clamping member 310 also includes an extension portion 313, which is disposed at one end of the mounting cylinder portion 311. The extension portion 313 has an upward-facing arcuate support surface 314, which is flush with the inner wall surface 316 of the mounting cylinder portion 311. Thus, the extension portion 313 provides support for the bent section 23, making the bent section 23 more stably installed.
[0069] In some embodiments, such as Figure 5 As shown, the first positioning assembly 200 includes a plurality of first positioning elements 210, which are sequentially arranged on the support 100 in a left-right direction. Each first positioning element 210 is axially movable along the first positioning groove 201. Each first positioning element 210 is provided with a sub-positioning groove 202, and the plurality of sub-positioning grooves 202 form the first positioning groove 201. Thus, the straight pipe section 22 is supported and positioned by the plurality of first positioning elements 210, thereby improving the stability of the installation of the straight pipe section 22.
[0070] Specifically, the support 100 is provided with a guide rail extending in the left and right direction, and the lower end of each first positioning member 210 is provided with a second guide groove that cooperates with the guide rail, so that each first positioning member 210 can move in the left and right direction.
[0071] Furthermore, the opening of the first positioning groove 201 is horizontally oriented, and the first positioning component 200 also has a horizontal support surface 203, which is connected to the lower end of the first positioning groove 201. The horizontal support surface 203 can support the straight pipe section 22, and during the installation of the straight pipe section 22, the horizontal support surface 203 can guide the straight pipe section 22, allowing it to fit more smoothly into the first positioning groove 201.
[0072] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
