Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plasma arc welding, in particular to a high-end aluminum alloy tool post-plasma welding machine tool. BACKGROUND

[0002] In modern architecture and space design, when our eyes turn to the forefront of material technology, aluminum alloy, as an advanced non-ferrous metal material, is redefining the benchmark of high-end rail with its outstanding comprehensive performance. Choosing aluminum alloy to make rail is not only choosing a lightweight, durable and maintenance-free practical solution, but also choosing an advanced material language that coexists with technology and art, facing the future, and writing an elegant note full of modernity for building facades and space. Railings are widely used in residential balconies, highway isolation belts, commercial area fences, public place protection and other fields, and its core function is to provide safety protection and structural support. A typical hardware railing is composed of a support column and a horizontal rod and is fixedly connected through welding. The support column is usually a hollow circular tube structure and is installed vertically on the ground to bear the weight and stability requirements of the whole railing. The horizontal rod is generally a flat steel or square tube structure and has a circular groove or semicircular groove in the middle to surround the support column and enhance the bending rigidity and impact resistance of the overall structure.

[0003] In the existing welding production process of metal horizontal rods and support columns, manual or semi-automatic methods are usually used for feeding, assembling and welding. In the traditional method, workers need to manually wrap the horizontal rod around the outside of the support column while ensuring that the two are in close contact, and finally fix them through welding equipment. This method is not only low in efficiency, but also prone to inaccurate welding positions due to human operation errors, affecting product consistency. Some automatic welding equipment has a complex structure and can only complete a single welding action, which cannot realize automatic feeding, precise positioning and synchronous assembly welding of the support column and the horizontal rod. In addition, the existing technology uses external clamps to clamp the support column, which can easily damage the surface of the workpiece. Therefore, a high-end aluminum alloy tool post-plasma welding machine tool is proposed to solve the above problems. SUMMARY

[0010] Preferably, the inside of the support column storage bin is fixedly connected with two guide plates, the top of each of the two guide plates is provided with a feeding mechanism arranged symmetrically, each group of feeding mechanism includes a separation plate, the separation plate is slidably connected with the support column storage bin, and the side of the separation plate away from the support column storage bin is fixedly connected with a sliding block one.

[0011] Preferably, the outer wall of the sliding block one is slidably connected with a push block one, the bottom of the push block one is fixedly connected with a connecting rod one, and the end of each of the two connecting rod ones away from the push block one is fixedly connected with a same inclined push block two.

[0012] Preferably, the inside of the inclined push block two is slidably connected with a slide rail frame, the end of the slide rail frame is fixedly connected with an abutting plate, the slide rail frame is fixedly connected with the support column storage bin, and the inclined push block two and the abutting plate are fixedly connected with two first springs.

Simultaneously, the separating plate supports the stacked workpieces above, preventing squeezing interference and ensuring stable sliding of individual pieces onto the inner cylinder, achieving precise feeding. The slide rod one slides along the loop-shaped limiting slide rail, and through rack and gear, the inner push rod drives the inner clamping plate to clamp the workpiece from the inside, avoiding surface damage caused by traditional external clamping and improving clamping stability. When the support column body moves to below the crossbar storage compartment, it automatically pushes the crossbar body out and bends its ends inward through the two limiting plates, completing precise assembly, ensuring consistent welding positions, and improving product quality. After welding, the circular base continues to move to the reset inclined surface of the loop-shaped limiting slide rail, causing the inner clamping plate to automatically release, allowing the workpiece to be smoothly unloaded without manual operation, achieving full-process automation. This solution achieves full-process automation from automatic feeding, precise assembly, stable clamping, efficient welding to automatic unloading, significantly improving production efficiency, welding accuracy, and product consistency, while reducing labor costs and the risk of workpiece damage.
