Description

Technical Field

[0001] This utility model relates to auxiliary tooling for welding air conditioning pipes, and more specifically, to a welding positioning device that can be adapted to J-shaped pipes of different angles. Background Technology

[0002] Air conditioning equipment contains many copper pipes, which are typically connected by welding. Multiple branch pipes are usually welded onto the main air conditioning line. A welding positioning device is needed to limit and fix the straight pipes to be welded and the unwelded straight pipes of the J-shaped pipes, facilitating subsequent welding work. The unwelded straight pipes of the J-shaped pipes in air conditioning equipment have various bending angles due to design requirements. Traditional positioning devices often use fixed clamping structures, which can only accommodate straight pipes with specific angles. When dealing with J-shaped pipes of different angles, frequent changes of special clamps or manual adjustment of positioning components are required, resulting in low production efficiency and difficulty in guaranteeing positioning accuracy. For example, patent application number 202121154152.9 discloses a high-efficiency welding fixture that can simultaneously weld multiple automotive air conditioning pipes. However, this welding fixture can only fix and support pipes with specific angles. When dealing with pipes with different angles, frequent changes of clamps are required, or multiple different clamps need to be set up on the same production line. As per the appendix of this utility model... Figure 2-4 As can be seen, the welding joints on the J-shaped tube are in different positions. During welding, the installation angle of the J-shaped tube needs to be adjusted according to the welding position. The general-purpose clamps cannot be adapted to J-shaped tubes with different welding joints. Utility Model Content

[0032] like Figure 1 The welding positioning device shown is adaptable to J-shaped tubes of different angles, including: a fixed bracket 1, the top of which is provided with a fixing block 4 that engages with a plurality of branch tubes 3 to be welded on the straight tube 2 of the J-shaped tube to be welded, and further including: a fixing component I 5 that is slidably disposed on the fixed bracket 1 to limit the straight tube 2 of the J-shaped tube to be welded, and a fixing component II that limits the unwelded straight tube 6 of the J-shaped tube, the fixing component II being located below the fixing component I 5;

[0033] The fixing component II includes: a slide block I8 slidably mounted on the fixing bracket 1 via a transmission component 7, the slide block I8 being rotatably mounted on the transmission component 7, and a support rod 9 slidably mounted on the slide block I8 to support unwelded straight tubes at different angles of the J-shaped tube, and a support block 10 cooperating with the J-shaped tube is provided at one end of the support rod 9.

[0034] Working principle:

[0035] Before starting the welding positioning of the J-shaped tube, the positions of fixing components I5 and II on the fixing bracket 1 are initially adjusted according to the approximate specifications and shape of the J-shaped tube. Since both fixing components I5 and II are slidably mounted on the fixing bracket 1, they can slide up and down along the fixing bracket 1 so that their positions can roughly match the positions of the straight tube to be welded and the unwelded straight tube of the J-shaped tube.

[0036] Simultaneously, the J-shaped tube is placed on the fixed support 1, so that the multiple branch pipes 3 on the straight pipe to be welded on the J-shaped tube are engaged with the fixing block 4 at the top of the fixed support 1. The function of the fixing block 4 is to accurately fix the position of the branch pipes 3 to be welded, preventing the branch pipes from shifting during subsequent welding. The fixing component I5 is used to limit the straight pipes 2 to be welded on the J-shaped tube. The straight pipe to be welded is firmly fixed in a specific position. The slide I8 in the fixing component II slides on the fixed support 1 through the transmission component 7. First, the slide I8 is adjusted to a suitable height position to correspond to the position of the unwelded straight pipe of the J-shaped tube. Since the slide I8 is rotatably set on the transmission component 7, the slide I8 is rotated according to the specific angle of the unwelded straight pipe of the J-shaped tube to make it fit the angle that can be adapted to the unwelded straight pipe. After the position and angle of the slide I8 are adjusted, the support rod 9 slidably set on the slide I8 begins to function. Based on the specific shape and dimensions of the unwelded straight tube of the J-shaped tube, the sliding support rod 9 is moved so that the support block 10 at one end of the support rod 9 approaches the unwelded straight tube 6 of the J-shaped tube. The support block 10 cooperates with the unwelded straight tube 6 of the J-shaped tube (a V-shaped groove is provided on the contact surface between the support block 10 and the unwelded straight tube 6 of the J-shaped tube), providing effective support. The shape and structure design of the support block 10 can fit well with the surface of the J-shaped tube, ensuring a stable support force for the unwelded straight tube, guaranteeing the stability of the J-shaped tube during the welding process, and preventing it from shaking. This device, through the slide block 18, support rod 9, and support block 10, can quickly position and adjust the J-shaped tube at different welding joint positions. Compared with traditional welding positioning methods, it reduces positioning and adjustment time, improves welding efficiency, and allows welding work to be carried out more efficiently.

[0037] In the above technical solution, the transmission component 7 includes a connecting rod I12 slidably mounted on the fixed bracket 1 via a slider I11; wherein the slide block I8 is rotatably mounted on the connecting rod I12. Using this technical solution, the sliding engagement between the slider I11 and the fixed bracket 1 allows the connecting rod I12 to move along the fixed bracket 1. When welding and positioning J-shaped tubes of different specifications, the height of the connecting rod I12 can be quickly and accurately adjusted according to the actual position of the unwelded straight section of the J-shaped tube. Simultaneously, the slide block I8 can both rotate and slide on the connecting rod. When the curvature of the unwelded straight section of the J-shaped tube varies, support for the unwelded straight section of the J-shaped tube can be achieved by quickly sliding the slide block I8.

[0038] In the above technical solution, the slide block I8 has a through hole 13 for the support rod 9 to extend into; wherein, on the side wall of the through hole 13, the slide block I8 has a limiting hole I17 communicating with the through hole 13, and a fixing member I14 is provided in the limiting hole I17 to limit the position of the support rod 9. With this technical solution, the through hole 13 on the slide block I8 allows the support rod 9 to freely extend or retract. The extension length of the support rod 9 can be flexibly adjusted according to the actual position and shape of the unwelded straight pipe. The fixing member I14 and the limiting hole I17 can securely fix the support rod 9 to the slide block I8 after it has been adjusted to a suitable position. The fixing member I14 can be a pin or bolt, etc.

[0039] In the above technical solution, the fixing component I5 includes: a connecting rod II52 slidably mounted on the fixed bracket 1 via a slider II51; at least two slide blocks II53 are provided on the connecting rod II52; a support member 54 passes through the surface of each slide block II53; and a limiting groove 55 adapted to the shape of the straight pipe 2 to be welded in the J-shaped tube is opened at one end of the support member 54. With this technical solution, the connecting rod II52 is slidably mounted on the fixed bracket 1 via the slider II51, allowing the fixing component I5 to slide up and down along the fixed bracket 1. When dealing with J-shaped tubes of different lengths and heights, the height of the connecting rod II52 can be flexibly adjusted according to the actual situation, so that the fixing component I5 can accurately correspond to the position of the straight pipe 2 to be welded in the J-shaped tube. The connecting rod II52 is provided with at least two slide blocks II53, and multiple slide blocks II53 can limit the straight pipe 2 to be welded in the J-shaped tube from different positions. Compared to a single support point, multiple support points provide more stable support and fixation, reducing the shaking or displacement of the J-shaped tube during welding due to uneven force. The limiting groove 55 at one end of the support member 54, which is adapted to the shape of the straight tube to be welded to the J-shaped tube, can fit tightly against the surface of the J-shaped tube. This fitting design can effectively restrict the movement of the J-shaped tube in both the horizontal and vertical directions.

[0040] In the above technical solution, the angle of the support rod 9 can rotate on the through hole 13, and the angle of the support block 10 also changes accordingly. Figure 5 As shown, since the unwelded straight tube 6 of the J-shaped tube also has various bending angles, the support rod 9 adjusts the angle of the support block 10 by rotating, allowing the support block 10 to be rotated and adjusted accordingly to the actual angle of the J-shaped tube. Regardless of whether the unwelded straight tube 6 of the J-shaped tube is horizontal, inclined, or at other special angles, the support block 10 can be rotated to fit its surface, thus providing effective support. This greatly enhances the adaptability of the device to J-shaped tubes of different angles, improving the versatility and flexibility of the device.

[0041] In the above technical solution, the surface of the support block 10 is provided with a mounting hole 1011 for the support rod 9 to extend into; wherein, on the side wall of the mounting hole 1011, the support block 10 has a limiting hole II 1012 communicating with the mounting hole 1011, and a fixing member II 1013 for limiting the position of the support rod 9 is provided in the limiting hole II 1012. Using this technical solution, such as... Figure 4 As shown, when the angle between the weld joint of the J-shaped tube and the unwelded straight tube is too large (reaching 90 degrees), and the weld joint must be kept perpendicular in the spatial direction during welding, a single support rod 9 cannot provide good support. By setting another support rod 9 on the support block 10 of one support rod 9, the unwelded straight tube 6 of the J-shaped tube is supported by the support block 10 on the other support rod 9. The two support rods 9 form a combined support. At the same time, the fastener II 1013 also uses pins or bolts to limit the length and position of the adjusted support rod 9.

[0042] In the above technical solution, a waist-shaped hole 15 is provided on the top of the fixed bracket 1, and each fixing block 4 is slidably disposed in the waist-shaped hole 15 by means of a bolt assembly 16. Using this technical solution, the distribution and spacing of the branch pipes 3 to be welded on the straight pipes to be welded will vary for different J-shaped tubes. The design of the waist-shaped hole 15 allows the fixing block 4 to slide freely within a certain range, and the position of the fixing block 4 on the top of the fixed bracket 1 can be flexibly adjusted according to the specific branch pipe position of the J-shaped tube, thereby allowing the fixing block 4 to be precisely engaged with the branch pipe 3 to be welded. The bolt assembly 16 can firmly fix the fixing block 4 in any position within the waist-shaped hole 15, ensuring that the fixing block 4 will not shift during the welding process.

[0043] In the above technical solution, a groove adapted to the shape of the branch pipe 3 is formed on the side wall of the fixing block 4 that mates with the branch pipe 3 to be welded. With this technical solution, because the groove matches the shape of the branch pipe 3, when the branch pipe 3 of the J-shaped tube is inserted into the groove, the two can fit tightly together. This tight fit effectively restricts the movement of the branch pipe 3 in the horizontal and vertical directions, ensuring that the branch pipe is in an accurate position during welding, thereby improving the overall positioning accuracy of the J-shaped tube, ensuring the accuracy and consistency of welding, and reducing welding defects caused by branch pipe position deviations.

[0044] The slider I11, slider II51, slide block I8 and slide block II53 are all provided with pins that limit their angle and height position. These pins can also be replaced with bolts or other fixing components.

[0045] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
