Description

Technical Field

[0001] The invention relates to the technical field of laser welding equipment, and in particular to a laser equipment for welding pipelines. Background Art

[0002] The current laser equipment is a modern mechanical equipment that uses a high-energy-density laser beam as a heat source. Due to the optical properties of lasers such as refraction and focusing, laser welding is very suitable for welding micro parts and parts with poor accessibility. Laser welding also has the characteristics of low heat input, small welding deformation, and is not affected by electromagnetic fields.

[0003] In order to solve the problem that "existing equipment is inconvenient to fix the pipeline", the Chinese patent with publication number CN117961333B discloses a laser device for welding pipelines, which includes: a base and a starting mechanism, the top of the base is slidably connected to two sliding seats, and the bottom of the base is provided with a driving mechanism for driving the two sliding seats to move closer and farther from each other; a rotating drum is rotatably installed inside the sliding seat, and a clamping mechanism that can clamp round pipes, square pipes and elliptical pipes is provided inside the rotating drum, and a rotating mechanism for driving the two rotating drums to rotate synchronously is provided on the top of the base. The present invention can meet the requirements of clamping and fixing elliptical pipes and square pipes, and can control the automatic docking and synchronous rotation of the pipes. Through the cooperation of the rotating wheel and the reset spring, the two laser welding machines are attached to the inner and outer walls of pipes of different shapes for welding, which improves the applicability, and automatically stops the welding work when the pipe docking is misaligned, ensuring the welding efficiency while ensuring the welding quality. Although the existing technical problems have been solved, the following problems still exist: In this technical solution, before welding, the two pipes need to be manually fixed to the corresponding rotating drums respectively, and the operating space is narrow. After welding, the pipes need to be manually released and moved out, which results in cumbersome operation and low efficiency. Therefore, corresponding improvements are made to address this problem. Summary of the invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a laser device for welding pipelines.

[0006] Preferably, the support plate is provided with a socket for inserting the baffle, a bracket is fixed at the discharge end of the table plate, a pair of electric push rods are fixed on the bracket, a pair of ears that can contact the output shaft of the electric push rod are provided on the top of the baffle, and an opening for the baffle to enter is provided at the discharge end of the table plate, which is located between the two electric push rods. When the baffle moves to the opening, the baffle will fall into the opening due to gravity, thereby removing the obstruction to the pipeline, and then the worker can directly remove the pipeline. After the pipeline is removed, the output shaft of the electric push rod will push the ears to push the baffle upward to the initial height, and then the motor will drive the support plate to reset through the screw rod, at this time the support plate will take the baffle away, and then the electric push rod will reset to the initial position.

[0007] Preferably, the bracket is connected to a buffer plate located below the opening via a pair of springs, and a pair of guide pillars passing through the bracket are fixed to the bottom of the buffer plate, so that when the baffle falls downward, it will fall onto the buffer plate, and then the spring will elastically expand and contract, thereby buffering the baffle.

[0008] Preferably, a conveying platform is fixed on both sides of the feed end of the table plate, a sliding mouth is opened at the bottom of the conveying platform, a push plate is slidably connected in the sliding mouth, a second motor is fixed at the bottom of the conveying platform, a second screw is connected to the output shaft of the second motor, and the second screw is threadedly connected to the push plate.

The push plate will push the pipe onto the support plate, and then the two pipes will be connected together, so there is no need for manual loading.

[0009] Taking into account that the welding machine has a long moving stroke, the wires on the welding machine will also be long. When the welding machine is close to the power source, the wires will be dragged on the ground. In order to avoid the wires dragging on the ground all the time, it is preferred that a rotatable main shaft is provided at the bottom of the table, and a wire take-up rack is fixed to the bottom end of the main shaft. The wire take-up rack is provided with two slots for inserting the wires of the welding machine. The main shaft is connected to a drive rotation assembly to insert the wires into the two slots. The length of the wire is sufficient to ensure that the wires do not drag on the ground when the frame moves to the farthest distance. At this time, the wires are approximately in a straightened state. When the frame moves back, the main shaft and the wire take-up rack are driven to rotate through the drive rotation assembly, and the wire take-up rack bends the middle position of the wire so that the wire forms a Z shape, thus avoiding the wires dragging on the ground.

[0011] Preferably, the driving assembly includes a rotating part connected to the top of the main shaft, a reel is fixedly sleeved on the main shaft, a pull rope is wound around the reel, and the free end of the pull rope is fixed on the frame. When the frame moves toward the discharge end of the table, the reel will be driven to rotate through the pull rope, and the reel will synchronously drive the main shaft to rotate. Conversely, when the frame resets and moves, the rotating part will drive the main shaft to rotate in the opposite direction, so that the reel will reel up the pull rope.

[0012] Preferably, the rotating part includes an upper cover, a lower cover and a coil spring, the top of the upper cover is fixedly connected to the table plate, the upper cover and the lower cover are rotatably connected, the coil spring is installed between the upper cover and the lower cover, and the lower cover is fixedly connected to the main shaft. When the main shaft rotates, the lower cover will be driven to rotate synchronously, and then the lower cover will tighten the coil spring, so that when the frame is reset and moved, the coil spring can be used to drive the main shaft to rotate in the opposite direction.

[0014] 2. A laser device for welding pipes, which is equipped with a movable baffle. When the baffle moves to the opening, it will fall into the opening due to gravity, thus removing the obstruction to the pipe. Then the worker can directly take the pipe down. After the pipe is taken away, the output shaft of the electric push rod will push the ear to push the baffle upward to the initial height, and then the motor will drive the support plate to reset through the screw rod. At this time, the support plate will take the baffle away together, and then the electric push rod will reset to the initial position.

[0015] 3. A laser device for welding pipes, which places the wire into two slots by setting a wire take-up rack. The length of the wire is sufficient to prevent the wire from dragging on the ground when the frame moves to the farthest distance. At this time, the wire is approximately in a straightened state. When the frame moves back, the main shaft and the wire take-up rack are driven to rotate through the driving assembly, and the wire take-up rack bends the middle position of the wire to form a Z shape, thereby preventing the wire from dragging on the ground.

[0016] 4. A laser device for welding pipes, which is provided with a toothed belt. When the frame moves, the toothed belt is driven to move through the clamping plate, and the toothed belt will rotate between two pulleys, and then the toothed belt will drive the main shaft to rotate through the pulley two.

The length of the wire is sufficient to ensure that the wires do not drag on the ground when the frame 4 moves to the farthest distance. At this time, the wires are approximately in a straightened state. When the frame 4 moves back, the main shaft 24 and the wire take-up frame 25 will be driven to rotate by the driving assembly, and the wire take-up frame 25 will bend the middle position of the wire so that the wire forms a Z shape, thereby avoiding the wires from dragging on the ground.
