Description

Technical Field

[0001] This invention relates to the field of pipe welding technology, and in particular to a pipe welding machine that facilitates pipe docking and positioning. Background Technology

[0002] A pipeline is a tubular device used to transport fluids or solid materials, including overhead pipelines, buried pipelines, and trench pipelines. When welding pipelines, a pipe welding machine is required. A pipe welding machine is a special automated or semi-automated equipment used to weld pipes together. To this end, patent CN221247576U discloses a pipe welding machine, including a sleeve with a clamping structure inside. A steel pipe is mounted on the clamping structure for use with it. A gear is fixedly connected to the middle of the outer side of the sleeve. Support members are connected to the front and rear ends of the bottom of the sleeve by bearings. Sliding holes are opened on both sides of the bottom center of the support member, and sliding columns are slidably connected within the sliding holes. Threaded blocks are fixedly connected to the bottom ends of both sides of the support member, and threaded rods are threadedly connected within the threaded blocks. Drive modules are provided at the front and rear ends of the threaded rods and sliding columns. A base plate is fixedly connected to the bottom of the drive modules. Gears are provided on both sides below gear one and mesh with it. A motor is provided at the front end of gear two to drive its rotation. The advantage of this utility model is that by designing a novel clamping structure, the specifications of the clamped welded pipe are adjustable, enriching the application scenarios of the equipment. Existing pipe welding machines typically use two independent systems to achieve pipe docking and positioning, resulting in poor linkage effect, cumbersome operation, and reduced welding efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a pipe welding machine that facilitates pipe docking and positioning, thereby overcoming the shortcomings of existing pipe welding machines in terms of poor pipe docking and positioning performance.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pipe welding machine for easy pipe docking and positioning, comprising a pipe welding machine frame, a drive cylinder mounted on the pipe welding machine frame, and a welding head provided at the output end of the drive cylinder, the welding head being connected to a control component, a welding station mounted at the bottom end of the pipe welding machine frame, and support frames symmetrically arranged at the top end of the welding station, on which a pipe body is placed, the support frames being connected to a drive mechanism, the drive mechanism including a bidirectional screw mounted at the top end inside the base and a drive motor mounted at one end of the bidirectional screw, the support frames being threadedly connected to the bidirectional screw, and the support frames being located away from the welding head. A rotating mechanism is provided on the side of the support frame. A positioning structure is provided on the welding platform near the welding head. The positioning structure includes a stand installed on the welding platform near the welding head of the support frame, a limiting screw installed inside the stand, a movable block threadedly connected to the limiting screw, a second telescopic rod installed at the top of the movable block, a positioning pressure plate installed at one end of the second telescopic rod, a second limiting roller evenly installed inside the positioning pressure plate, a second gear installed at the bottom end of the limiting screw, a connecting shaft installed at the bottom end of the stand, and a first gear symmetrically installed on the connecting shaft. The connecting shaft is connected to the bidirectional screw via a belt assembly.

[0005] Preferably, the rotating mechanism includes a support plate, a first telescopic rod, a clamp, a rotating shaft, and a fixed motor. The first telescopic rod is symmetrically installed on the side of the support frame away from the welding head. A support plate is installed on one side of each of the first telescopic rods, and a fixed motor is installed on each support plate. A rotating shaft is installed at the output end of each fixed motor, and a clamp is installed at one end of each rotating shaft.

[0006] The above structure allows the pipe body to rotate, enabling welding of the pipe body from all angles.

[0007] Preferably, the first telescopic rod is composed of a first bushing, a first adjusting screw, and a first fixing rod. The first fixing rod is fixedly connected to the support frame, the bushing is fixedly connected to the support plate, and a first adjusting screw is installed on one side of the bushing. The first adjusting screw and the first fixing rod are threaded together.

[0008] The above structure allows for fine-tuning of the position of the positioning plate, enabling it to press and position pipes of different diameters during docking.

[0009] Preferably, rollers are installed at the bottom end of each of the support plates.

[0010] The above structure can assist in the movement of the support plate and improve its movement efficiency.

[0011] Preferably, the support frame has a V-groove, and a first limiting roller is evenly installed on the V-groove.

[0012] With the above structure, the first limiting roller can assist in limiting the rotation of the pipe body, thereby improving the rotation efficiency.

[0013] Preferably, a protective structure is provided on the welding platform near the welding head of the support frame. The protective structure includes a vertical plate, a positioning groove, a telescopic spring, and a sealing gasket. The vertical plates are all installed on the welding platform near the welding head of the support frame. Each vertical plate has a positioning groove, and a telescopic spring is evenly installed inside the positioning groove. A sealing gasket is installed at one end of each telescopic spring.

[0014] The above structure can block welding slag during welding, preventing slag from splashing and adhering to the positioning pressure plate.

[0015] Preferably, one end of the sealing gasket is disposed inside the positioning groove, and the sealing gasket and the telescopic spring form a telescopic structure.

[0016] Through the above structure, the telescopic spring moves the sealing gasket, causing it to contact the surface of the pipe body with different diameters.

[0017] Preferably, the side of the sealing gasket away from the welding head has an arc structure.

[0018] The above structure allows the pipe body to quickly pass through the vertical plate when the support frame moves it.

[0019] Preferably, the second telescopic rod is composed of a second fixed rod, a second bushing, and a second adjusting screw. The second fixed rod is fixedly connected to the movable block, and the second bushing is fixedly connected to the positioning pressure plate. The top end of the second bushing is equipped with a second adjusting screw, and the second adjusting screw and the second fixed rod form a threaded connection.

[0020] The above structure allows for fine-tuning of the clamp position so that the clamp can hold pipe bodies of different lengths during docking.

[0021] Preferably, the positioning plate has a V-shaped groove.

[0022] The above structure increases the contact area between the positioning plate and the pipe body, thereby improving the positioning effect.

[0023] The present invention provides a pipe welding machine that facilitates pipe docking and positioning, the advantages of which are: The drive mechanism starts the motor, the bidirectional screw rotates, the support frame moves the pipe body to dock. At the same time, the belt assembly drives the connecting shaft to rotate, the first gear drives the second gear to rotate, the limit screw rotates, the movable block drives the second telescopic rod to move, and adjusts the height of the positioning plate so that the positioning plate contacts the pipe body when docking, thus achieving the purpose of pressing and positioning it. Furthermore, by rotating the second adjusting screw, the second bushing drives the positioning plate to move, thereby achieving the purpose of fine-tuning the position of the positioning plate so that the positioning plate can press and position pipe bodies of different diameters during docking, thus improving the performance. Furthermore, through the rotating mechanism, when the support frame drives the pipe body to move and connect, the first telescopic rod drives the support plate to move, the clamp contacts the pipe body, the fixed motor starts, the rotating shaft drives the clamp to rotate, so that the pipe body can be rotated in all directions to improve welding efficiency. Furthermore, by rotating the first adjusting screw, the first bushing drives the support plate to move, fine-tuning the position of the clamp so that the clamp can hold pipe bodies of different lengths during docking, thereby improving the performance. With the protective structure in place, when the support frame moves the pipe body, the pipe body passes through the vertical plate. The telescopic spring moves the sealing gasket, making it contact the surface of the pipe body, which improves the sealing between the vertical plate and the pipe body and plays a certain role in blocking welding slag, thus preventing welding slag from splashing and adhering to the positioning pressure plate during welding.
