Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding equipment, specifically to a base for a pipe welding machine. Background Technology
[0002] Welding pipe fittings typically requires appropriate fixing devices, especially for connecting large pipe components, to facilitate welding operations. However, existing welding machines are usually designed with suitable bases based on common pipe welding requirements, limiting their application to the specific pipe joint. This often results in the use of simple molds; the pipes are simply fixed in place, and the welding machine moves to weld them. But when joining multiple pipe sections or irregularly shaped fittings like tees, using fixed molds becomes inconvenient for alignment and movement. Furthermore, designing a fixed base only for a specific joint pattern restricts welding to fixed joints, preventing flexible adaptation to different pipe connection methods. Utility Model Content
[0003] To address the problems existing in the prior art, the present invention aims to provide a base for a pipe welding machine. This invention enables the flexible application of the pipe welding machine, particularly for the automatic welding of large pipes, and is adaptable to processes such as splicing, repairing, and continuous welding of multiple pipe sections.
[0004] The present invention discloses a pipe welding machine base, comprising a base plate assembly. A first movable mechanism and a second movable mechanism are respectively arranged opposite to each other along the length of the base plate assembly. A third movable mechanism is provided between the first and second movable mechanisms along the width of the base plate assembly. The first movable mechanism is provided with a first mounting seat for mounting a push plate or a first pipe fitting bracket. The first movable mechanism is used to push the pipe fitting towards the second movable mechanism via the push plate or the first pipe fitting bracket. The second movable mechanism is provided with a mounting frame, which is provided with a plurality of second mounting seats for mounting second pipe fitting brackets. The second movable mechanism is used to adjust the position of the main pipe fitting by sliding the mounting frame and the second mounting seats left and right. The third movable mechanism is provided with a third mounting seat for mounting a third pipe fitting bracket. The third movable mechanism is used to adjust the position of the supplementary pipe fitting by sliding the third pipe fitting bracket back and forth.
[0005] In one embodiment, the first movable mechanism includes a first cylinder fixed on the base plate assembly, with first guide rails on both sides of the first cylinder, and the first mounting seat connected to the movable rod of the first cylinder and slidably connected on the two first guide rails.
[0006] In one embodiment, the second movable mechanism includes a second cylinder and a third cylinder arranged side by side on the base plate assembly. The second cylinder and the third cylinder are respectively provided with second guide rails on both sides. The two second guide rails are respectively provided with a first slider and a second slider in the front-rear direction. The second cylinder is linked with the first slider, and the third cylinder is linked with the second slider.
[0007] In one embodiment, the mounting frame includes a frame body, with a telescopic part movably connected to one end of the frame body near the first movable mechanism. The telescopic part is provided with at least one second mounting seat and connected to the first slider. The second mounting seats on the frame body are arranged at intervals, and the other end of the frame body is connected to the second slider.

[0012] This invention enables flexible application of pipe welding machines, especially for automatic welding of large pipes. It can be adapted to processes such as splicing, repairing, and continuous welding of multiple pipe sections.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0019] like Figures 1-3As shown, a pipe welding machine base of this utility model includes a base plate assembly 1. A first movable mechanism 2 and a second movable mechanism 3 are respectively arranged opposite each other along the length of the base plate assembly 1. A third movable mechanism 4 is provided between the first movable mechanism 2 and the second movable mechanism 3 along the width direction of the base plate assembly 1. The first movable mechanism 2 is provided with a first mounting seat 5 for mounting a push plate or a first pipe fitting bracket. The first movable mechanism 2 is used to push the pipe fitting towards the second movable mechanism 3 via the push plate or the first pipe fitting bracket. The second movable mechanism 3 is provided with a mounting frame 6, and the mounting frame 6 is provided with several second mounting seats 7 for mounting second pipe fitting brackets. The second movable mechanism 3 is used to adjust the position of the main pipe fitting by sliding the mounting frame 6 and the second mounting seats 7 left and right. The third movable mechanism 4 is provided with a third mounting seat 8 for mounting a third pipe fitting bracket. The third movable mechanism 4 is used to adjust the position of supplementary pipe fittings by sliding the third pipe fitting bracket back and forth. This utility model enables flexible application of the pipe welding machine, especially for automatic welding of large pipe fittings, and can be adapted to processes such as splicing, repairing, and continuous welding of multiple pipe sections. For example, when two pipe sections need to be aligned for welding, one section can be placed on the first mounting base 5 and the other on the second mounting base 7. The two pipe sections are aligned by the control of the first movable mechanism 2 or the second movable mechanism 3 on the mounting bracket 6, and then welding can be performed using a welding machine. When a tee or corner pipe needs to be connected between the two pipe sections, the tee or corner pipe can be placed on the third mounting base 8 in the above situation. After the first movable mechanism 2 and the second movable mechanism 3 adjust the distance, the supplementary pipe section is inserted and aligned using the third movable mechanism 4, and welding can also be performed. Furthermore, when large pipe sections need to be spliced together, a push plate can be replaced on the first mounting base 5, and the main pipe section is placed on the second mounting base 7. The third mounting base 8 continuously feeds in the splicing sections of the pipe section. After each two sections are welded, the push plate, in conjunction with the second movable mechanism 3, pushes the pipe section to the other end of the second mounting base 7, thus completing continuous welding operations.
[0020] In one embodiment, the first movable mechanism 2 includes a first cylinder 21 fixed to the base plate assembly 1. First guide rails 22 are provided on both sides of the first cylinder 21. The first mounting seat 5 is connected to the movable rod of the first cylinder 21 and slidably connected to the two first guide rails 22. The first cylinder 21 mainly controls the left and right sliding of the first mounting seat 5. Sliding blocks can be provided at all four corners to ensure the stability of the movement of the first pipe bracket on it. The push plate can also be directly connected to the first cylinder 21, and the first guide rails 22 on both sides are used for stabilization, ensuring its linear movement and keeping the pipes on the first pipe bracket and the pipes on the second pipe bracket of the second movable mechanism 3 as much as possible on the same straight line.
[0021] Furthermore, the second movable mechanism 3 includes a second cylinder 31 and a third cylinder 32 arranged side-by-side on the base plate assembly 1. Second guide rails 33 are respectively provided on both sides of the second cylinder 31 and the third cylinder 32. A first slider 34 and a second slider 35 are respectively provided in the front-rear direction of the two second guide rails 33. The second cylinder 31 is linked with the first slider 34, and the third cylinder 32 is linked with the second slider 35. Before welding, the main body of the pipe is generally placed on top of the second movable mechanism 3. Depending on the needs, when the pipe is short, fine adjustments can be made by controlling the sliding of the first slider 34 using only the second cylinder 31, especially adjusting the position close to the first movable mechanism 2. When the pipe is long, the second cylinder 31 and the third cylinder 32 need to synchronously control the sliding of the first slider 34 and the second slider 35 on the two second guide rails 33 to ensure that the pipe moves linearly along the central axis. Furthermore, in conjunction with the second movable mechanism 3, the mounting frame 6 includes a frame body 61. A telescopic part 62 is movably connected to one end of the frame body 61 near the first movable mechanism 2. The telescopic part 62 has at least one second mounting seat 7 connected to the first slider 34. The second mounting seats 7 on the frame body 61 are spaced apart, and the other end of the frame body 61 is connected to the second slider 35. The frame body 61, relatively fixed to the second slider 35, is the main body of the mounting frame 6, supporting a large portion of the pipe fittings. The second mounting seats 7 on it also primarily serve a supporting function. The telescopic part 62 can clamp the end of the pipe fitting using the special second mounting seats 7. The position of the end of the pipe fitting can be adjusted by controlling the sliding of the first slider 34 with the second cylinder 31, thus completing fine-tuning. The third cylinder 32 can be connected to the frame body 61. Then, through the combined action of the second cylinder 31 and the third cylinder 32, the first slider 34, along with the entire mounting frame 6 and the second slider 35, slides on the two second guide rails 33.
[0022] In addition, the third movable mechanism 4 includes a third guide rail 41 and a fourth guide rail 42 mounted on the base plate assembly 1. A fourth cylinder 43 is slidably connected to the third guide rail 41. The third mounting base 8 is connected to the movable rod of the fourth cylinder 43 and slidably connected to the fourth guide rail 42. The third movable mechanism 4 mainly controls the movement of the supplementary pipe fitting. When not in use, the fourth cylinder 43 can be moved directly to slide along the third guide rail 41 and bring out the third mounting base 8. When in use, the fourth cylinder 43 can be moved to a suitable position, and the extension and retraction of its movable rod controls the sliding of the third mounting base 8 on the fourth guide rail 42, thereby continuously feeding in the supplementary pipe fitting.
[0023] In one embodiment, the base plate assembly 1 includes a first mounting plate 11, a second mounting plate 12, and a third mounting plate 13. The first mounting plate 11, the second mounting plate 12, and the third mounting plate 13 correspond one-to-one with the first movable mechanism 2, the second movable mechanism 3, and the third movable mechanism 4, respectively. The third mounting plate 13 has two layers, with the first mounting plate 11 and the second mounting plate 12 located on opposite sides of the third mounting plate 13 and fixedly connected by screws. The base plate assembly 1 is divided into three mounting plates according to each movable mechanism for easy disassembly and installation. Since the third mounting plate 13, in conjunction with the third movable mechanism 4, forms a two-layer structure with a certain thickness, the first mounting plate 11 and the second mounting plate 12 can be fixedly connected to it at their ends by screws. Simultaneously, the bottom of both the first mounting plate 11 and the second mounting plate 12 is provided with reinforcing plates 14 to support the length of the first mounting plate 11 and the second mounting plate 12, preventing the entire base from bending and deforming, which would affect the concentricity of the welded pipe fittings.
