Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to an integrated welded pipe joint and welding equipment. Background Art

[0002] Welded pipe, also known as welded steel pipe, is a steel pipe made by welding steel plates or strips after curling and forming. Welded pipes are widely used in industry, such as water supply, drainage, sewage treatment projects, mud transportation, marine water transportation, gas, steam, liquefied petroleum gas transportation, and as structural materials for bridges, roads, building structures, etc.

[0003] When welding two or more steel pipe sections, the two sections of the pipe need to be spliced ​​together first, and then the splicing is welded. However, the splicing and welding processes are generally implemented by two devices, and the connection between the two processes is not high. After splicing, the whole is moved to the welding device for welding. It is easy to offset during the movement, which not only affects the accuracy of welding, but also affects the welding efficiency. Therefore, we propose an integrated welded pipe splicing seam and welding equipment. Summary of the invention

[0004] The object of the present invention is to provide an integrated welded pipe joint and welding equipment to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an integrated welded pipe joint and welding equipment, comprising an equipment base, a welding frame, a welding head, a driving chassis and a clamping chassis, wherein the welding frame is fixed to the top of the equipment base, the welding head is arranged below the welding frame, an adjusting base is fixed to the top of the equipment base below the welding head, a second motor is installed inside the adjusting base, and a bidirectional screw rod is installed at the output end of the second motor, push racks are arranged on both sides of the top of the adjusting base, and an arc-shaped positioning plate is fixed to the top of the push rack, and the The bottom end of the push frame extends to the interior of the adjusting base and is threadedly sleeved with the bidirectional screw rod. The clamping chassis are installed on both sides of the adjusting base, and a hollow turntable is rotatably installed inside the clamping chassis. A third cylinder is installed inside the hollow turntable, and an arc-shaped clamping plate is installed at the output end of the third cylinder. The driving chassis is fixed on one side of the clamping chassis, and a fourth cylinder is installed at the top and bottom of the driving chassis, and a friction wheel is installed at the output end of the fourth cylinder. A third motor is installed on the outer wall of the friction wheel, and the output end of the third motor is fixedly connected to the friction wheel.

[0006] Furthermore, support brackets are fixed on both sides of the top of the equipment base.

[0007] Furthermore, a guide seat is fixed on the top of the welding frame, a slide bar is fixed inside the guide seat, and a movable seat is slidably sleeved outside the slide bar.

[0008] Furthermore, a second cylinder is installed on one side of the top of the guide seat, and an output end of the second cylinder is fixedly connected to the movable seat.

[0009] Furthermore, a first cylinder is installed at the bottom end of the movable seat, and an output end of the first cylinder is fixedly connected to the welding machine head.

[0010] Furthermore, a laser locator is installed on one side of the surface of the welding head, the second cylinder drives the movable seat to translate, and the movable seat drives the welding head to move, and the welding head is adjusted to align with the seam according to the laser beam emitted by the laser locator.

[0011] Furthermore, a gear is installed at the bottom of the clamping chassis, and a first motor is installed on one side of the gear, and an output end of the first motor is fixedly connected to the gear.

[0012] Furthermore, an outer gear ring is fixed on the outer wall of the hollow turntable, and the outer gear ring is tightly meshed with the gear.

[0013] Furthermore, a cooling fan is installed at the center position of the top of the adjustment base, and the cooling fan runs to dissipate heat from the welded joint.

[0014] Compared with the prior art, the present invention has the following beneficial effects: Place two sections of steel pipe on the support bracket, and pass the steel pipe through the hollow turntable inside the clamping chassis. Secondly, the fourth cylinder drives the friction wheel to move down, and the third motor drives the friction wheel to rotate, so that the steel pipes at both ends move closer to each other until they are docked. The joint of the steel pipe is located below the welding head. Then, the second motor drives the bidirectional screw to rotate, so that the two sets of push frames drive the arc positioning plates to move synchronously toward the joint of the steel pipe until the steel pipe is clamped. Since the arc positioning plates synchronously clamp the joints of the two sections of steel pipes, the joints of the steel pipes are aligned. Immediately afterwards, the third cylinder drives the arc clamping plate to clamp and fix the two sections of steel pipes, and the second motor drives the bidirectional screw to rotate in the opposite direction, so that the push frame drives the arc positioning plate to move away from the joint of the steel pipe. This design is convenient for automatic splicing of steel pipes, and can automatically align the steel pipe joints, thereby improving the accuracy of subsequent welding. The equipment integrates splicing and welding functions, has a high degree of connection, and the steel pipes can be directly welded after splicing, thereby improving the accuracy and efficiency of welding.
