Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a pipe welding device. Background Technology

[0002] Welding, as a key process for joining metallic materials, is widely used in various industries, such as automobile manufacturing, shipbuilding, and aerospace. The quality of the welding process directly affects the performance and safety of the final product. However, traditional manual welding methods face many challenges, especially in ensuring weld quality and product consistency.

[0003] Manual welding relies heavily on the welder's skill level and experience, which not only limits production efficiency but also introduces the risk of inconsistent product quality. Specifically, achieving the ideal weld penetration and maintaining its consistency during the welding process is quite difficult. This is because manual operation makes it challenging to precisely control factors such as welding speed, current intensity, and arc length, all of which directly affect weld quality. For example, welding too fast may result in insufficient penetration, leading to cold welds or incomplete penetration; conversely, welding too slow may cause overheating, deformation, and other problems. Furthermore, welders are prone to fatigue during prolonged work, further increasing the risk of defects such as leaks.

[0004] For the reasons mentioned above, manually welded products often exhibit significant quality fluctuations, especially during mass production, making it a major challenge to ensure consistent welding quality across every single product. Welding defects such as leaks not only weaken the structural strength of the product but may also pose safety hazards during use. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] like Figures 1 to 4 As shown, the pipe welding device 100 of this utility model embodiment includes a three-jaw chuck 1, a connecting seat 2, a first driving component 3, a second driving component 4, and a welding robot.

[0036] The three-jaw chuck 1 is provided with a clamping part 11. The clamping part 11 is used to clamp the workpiece.

[0037] The connecting seat 2 includes a connecting plate 21 and a base plate 22. The base plate 22 is located at the bottom of the connecting plate 21 and is fixedly connected to the connecting plate 21. The connecting plate 21 includes a first end face 211 and a second end face 212 arranged opposite to each other in the axial direction of the three-jaw chuck 1. The three-jaw chuck 1 is rotatably connected to the first end face 211.

[0038] The first driving member 3 is connected to the second end face 212, and the first driving member 3 is used to drive the three-jaw chuck 1 to rotate around its axis.

[0039] The second driving member 4 is located at the bottom of the base plate 22. The second driving member 4 is used to drive the connecting seat 2 to rotate around the first direction, which is perpendicular to the axis of the three-jaw chuck 1.

[0040] Welding robots include welding torches.

[0041] For ease of description, the technical solution of this application will be described below with the first direction as the up-down direction and the axis of the three-jaw chuck 1 as the left-right direction. The up-down direction and the left-right direction are as follows: Figure 1 As shown.

[0042] The three-jaw chuck 1 is equipped with a clamping part 11 for securely clamping the workpiece. The workpiece is typically a pipe. The base plate 22 is welded to the connecting plate 21 or connected by bolts.

[0043] The connecting plate 21 has a first end face 211 and a second end face 212, which are arranged opposite to each other along the axial direction of the three-jaw chuck 1. The three-jaw chuck 1 is rotatably connected to the first end face 211 of the connecting plate 21, so that the three-jaw chuck 1 can be flexibly rotated when needed.

[0044] The first driving member 3 is connected to the second end face 212 of the connecting plate 21. The first driving member 3 can provide rotational power for the three-jaw chuck 1 to ensure that the workpiece can be precisely processed.

[0045] The second driving component 4 is installed at the bottom of the base plate 22 and is specifically used to drive the entire connecting seat 2 to rotate in the up and down direction, thereby further increasing the operational flexibility and functionality of the entire device.

[0046] When the pipe welding device 100 is in operation, after the workpiece is fixed on the clamping part 11, the welding robot is started. The welding gun, the first drive component 3 and the second drive component 4 run according to the pre-set program to weld the workpiece.

[0047] In related technologies, when welding workpieces, manual welding cannot guarantee the consistency of weld penetration and is prone to defects such as leaks in the welded products, resulting in poor product consistency.

[0048] The pipe welding device 100 of this embodiment integrates a three-jaw chuck 1, a connecting seat 2, a first driving component 3, a second driving component 4, and a welding robot, achieving efficient and precise automatic welding of workpieces. Compared with traditional manual welding, automatic welding using the pipe welding device 100 not only significantly improves work efficiency but also effectively avoids problems such as inconsistent weld penetration and leaks caused by manual operation, resulting in more stable and reliable welding quality and improved product consistency. Furthermore, the automated welding process reduces human interference and lowers the labor intensity of workers.

[0049] Therefore, the pipe welding device 100 of this utility model embodiment can not only improve the quality of the workpiece, but also reduce the labor intensity of workers.

[0050] In some embodiments, such as Figure 1 As shown, the pipe welding device 100 includes a rotating assembly 5, which includes a support member 51 and a rotating member 52. One end of the support member 51 is fixedly connected to the first end face 211 in the axial direction of the three-jaw chuck 1, and the other end of the support member 51 is rotatably connected to one end of the rotating member 52. The other end of the rotating member 52 is fixedly connected to the three-jaw chuck 1.

[0051] One end of the support member 51 is fixedly connected to the first end face 211 of the connecting plate 21 in the left-right direction, while the other end of the support member 51 is rotatably connected to one end of the rotating member 52. For example, the support member 51 and the rotating member 52 are connected by a bearing.

[0052] The other end of the rotating component 52 is further fixedly connected to the three-jaw chuck 1. This design enables the three-jaw chuck 1 to rotate flexibly under the synergistic effect of the support component 51 and the rotating component 52, while ensuring the stability and reliability of the overall structure. In addition, the cooperation between the support component 51 and the rotating component 52 not only effectively reduces the eccentricity or vibration problems that may occur during the rotation of the three-jaw chuck 1, but also further improves the operating accuracy and service life of the device, thereby meeting the needs of high-precision machining of workpieces.

[0053] In some embodiments, such as Figure 2 As shown, the connecting seat 2 includes a reinforcing plate 23, which includes a first side and a second side. The first side is fixedly connected to the base plate 22, and the second side is fixedly connected to the second end face 212.

[0054] For example, the reinforcing plate 23 has a first side and a second side. The first side of the reinforcing plate 23 is the bottom surface of the reinforcing plate 23, and the first side of the reinforcing plate 23 is fixedly connected to the base plate 22, for example, by bolting or welding. The second side of the reinforcing plate 23 is fixedly connected to the second end face 212 of the connecting plate 21, for example, by bolting or welding.

[0055] This arrangement not only effectively enhances the connection rigidity between the base plate 22 and the connecting plate 21, but also reduces the deformation or vibration problems that may occur during equipment operation through the supporting role of the reinforcing plate 23, thereby improving the structural reliability and service life of the entire device. At the same time, the setting of the reinforcing plate 23 also provides a more stable foundation for the installation of other components, further optimizing the overall performance and practicality of the device.

[0056] In some embodiments, such as Figure 3 As shown, there are two reinforcing plates 23, which are arranged at intervals along the second direction, which is perpendicular to the first direction. The first driving member 3 is located between the two reinforcing plates 23.

[0057] For ease of description, the technical solution of this application will be described below with reference to the second direction as the front-back direction, wherein the front-back direction is as follows: Figure 1 As shown.

[0058] Two reinforcing plates 23 are arranged at intervals along the front-to-back direction, and the first driving member 3 is located between the two reinforcing plates 23. Thus, the two reinforcing plates 23 can not only effectively enhance the structural strength between the base plate 22 and the connecting plate 21, but also provide a stable installation position for the first driving member 3.

[0059] In some embodiments, such as Figure 4 As shown, the pipe welding device 100 includes a positioning component 6, which includes a follower 61 and a sensor 62. The follower 61 is fixedly connected to the three-jaw chuck 1 or the rotating component 52.

[0060] The sensor 62 is fixedly connected to the first end face 211, and the sensor 62 can detect whether the follower 61 is in the initial position.

[0061] For example, the positioning component 6 consists of a follower 61 and a sensor 62, wherein the follower 61 is fixedly connected to the three-jaw chuck 1 or the rotating component 52, for example, by bolting or welding. The follower 61 can move synchronously with the movement of the three-jaw chuck 1 or the rotating component 52, while the sensor 62 is fixedly mounted on the first end face 211 of the connecting plate 21 to detect whether the follower 61 is in the initial position.

[0062] The pipe welding device 100 of this utility model is designed to ensure that the three-jaw chuck 1 accurately returns to the preset initial state after each operation by the sensing element 62, thereby improving the stability and repeatability of the equipment operation. It can also provide timely feedback signals for adjustment when abnormal situations occur, further improving the automation level and operational reliability of the entire device. At the same time, this positioning mechanism also provides higher operational accuracy and consistency for welding or other processing tasks.

[0063] Optionally, the follower 61 and the sensing element 62 are a magnet and a Hall sensor, respectively.

[0064] In some embodiments, such as Figure 4 As shown, the support member 51 includes a first part 511 and a second part 512. The first part 511 and the second part 512 are arranged sequentially in the axial direction of the three-jaw chuck 1. The first part 511 is fixedly connected to the first end face 211. The cross-sectional area of ​​the second part 512 is smaller than that of the first part 511 so as to form a stepped surface on the first part 511.

[0065] The positioning component 6 includes a fixing member 63, one end of which is fixedly connected to the step surface, and the other end of which is fixedly connected to the sensing member 62.

[0066] For example, the support member 51 includes two parts, a first part 511 and a second part 512, arranged in the left-right direction. The first part 511 is located to the left of the second part 512 and is fixedly connected to the connecting plate 21.

[0067] The cross-sectional area of ​​the second part 512 is the projected area of ​​the second part 512 on a plane perpendicular to the left and right directions. The fixing member 63 is installed on the step surface to fix the sensing member 62.

[0068] The pipe welding device 100 of this utility model has a stepped surface to facilitate the installation of the fixing member 63, and the stepped surface is provided to leave installation space between the support member 51 and the three-jaw chuck 1, thereby facilitating the installation of the positioning component 6.

[0069] In some embodiments, such as Figure 4 As shown, the follower 61 includes a fixed part and an extension part. The fixed part is fixedly connected to the rotating part 52. The sensing part 62 includes two sensing parts arranged at intervals. The extension part can extend into the interval between the two sensing parts.

[0070] For example, the fixing part and the extension part are generally L-shaped. The fixing part is used to fix it to the rotating member 52, and the two sensing parts of the sensing member 62 are arranged opposite to each other and spaced apart in the left and right direction. One sensing part can emit light, and the other sensing part can detect light.

[0071] When the equipment is running, the extension can extend into the gap between the two sensing parts during the rotation of the three-jaw chuck 1 or the rotating part 52. Once the extension enters this gap and blocks the light, the light-detecting sensing part generates a corresponding signal. This signal is sent to the controller of the pipe welding device 100, and the controller determines that the three-jaw chuck 1 has returned to its initial position based on the received signal. This precise position detection mechanism significantly improves the positioning accuracy and reliability of the system.

[0072] The pipe welding device 100 of this embodiment not only ensures that the three-jaw chuck 1 accurately returns to the preset initial position after each operation, thus guaranteeing the consistency and accuracy of processing or welding tasks, but also allows for rapid adjustments when deviations occur, greatly improving production efficiency and product quality. Furthermore, this non-contact detection method reduces mechanical wear, extends equipment lifespan, and simplifies maintenance.

[0073] In some embodiments, the first drive element 3 is a servo motor, and / or the second drive element 4 is a rotary cylinder.

[0074] For example, the first driving component 3 is preferably a servo motor, which has high precision and high response speed, and can provide stable and precise rotational power for the three-jaw chuck 1, thereby meeting the strict requirements for angle and speed during workpiece positioning or processing; in addition, the second driving component 4 is a rotary cylinder, which can drive the connecting seat 2 to rotate around the upward direction.

[0075] In some embodiments, the connecting plate 21 has a through hole, through which the output shaft of the first drive member 3 passes and connects to the three-jaw chuck 1. The connecting plate 21 has a through hole to ensure that the output shaft of the first drive member 3 can smoothly pass through the through hole and connect to the three-jaw chuck 1.

[0076] In some embodiments, such as Figure 1 As shown, there are three clamping parts 11, which are spaced apart circumferentially along the three-jaw chuck 1. The three clamping parts 11 are evenly distributed circumferentially along the three-jaw chuck 1. This design not only ensures uniform force on the workpiece during clamping, thereby improving clamping stability and reliability, but also adapts to the needs of workpieces of different shapes and sizes, making the three-jaw chuck 1 more flexible and applicable in practical applications.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
