Description

Technical Field

[0001] This invention relates to the field of laser cladding technology, specifically to a laser cladding device. Background Technology

[0002] In modern industrial manufacturing and surface treatment, laser cladding technology is widely used in aerospace, machinery manufacturing, petrochemical and other industries due to its high precision, high efficiency and excellent surface modification effects. Especially in pipeline surface treatment, laser cladding can significantly improve the wear resistance, corrosion resistance and fatigue resistance of pipelines, effectively extending their service life. However, in actual working conditions, some pipelines have complex spatial structures with many non-planar parts such as inclined surfaces and curved surfaces, requiring cladding during hollow pipe processing.

[0003] According to patent document CN111719149B, a laser cladding device is disclosed, including a base, a mounting frame, a clamp body, a rotary motor, a guide frame, a slide, a laser cladding head, a powder feeding pipe, a support clamp, a guide arc plate, and an annular threaded block; two sets of mounting frames are set on the base, two sets of clamp bodies are rotatably connected to the two sets of mounting frames respectively, the guide frame is horizontally mounted between the two sets of mounting frames, and the slide is horizontally slidably connected to the guide frame; the support clamp includes two sets of clamp units hinged to the bottom of the slide, bolts that close and connect the bottom ends of the two sets of clamp units, and a sliding surface located on the inner side of the two sets of clamp units.

[0004] Traditional laser cladding devices typically use a fixed or simple mechanical cladding head, which has significant limitations when dealing with inclined pipe sections. The fixed cladding head cannot flexibly adjust the angle, making it difficult to ensure that the laser beam remains perpendicular to the pipe surface, resulting in problems such as uneven cladding layer thickness and insufficient bonding strength. Summary of the Invention

[0005] The purpose of this invention is to provide a laser cladding device to solve the problems mentioned in the background art. Traditional laser cladding devices usually use cladding heads with fixed or simple mechanical structures, which have obvious limitations when facing pipes with inclined angles. The fixed structure of the cladding head cannot flexibly adjust the angle and it is difficult to ensure that the laser beam is always perpendicular to the pipe surface, resulting in uneven cladding layer thickness and insufficient bonding strength.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser cladding device, comprising a worktable, an adjustment mechanism provided on one side of the worktable, the adjustment mechanism comprising a bracket, the bottom of the bracket being fixedly connected to the worktable, an electric telescopic rod being fixedly connected to the top of the bracket, a connecting plate being fixedly connected to the bottom of the electric telescopic rod, a first electric slide being fixedly connected to the bottom of the connecting plate, a horizontal plate being fixedly connected to the bottom of the first electric slide, a fixed plate being fixedly connected to the left front end of the top of the horizontal plate, a first motor being fixedly connected to the left side of the fixed plate, a lead screw being fixedly connected to the output end of the first motor, a threaded sleeve being threadedly connected to the surface of the lead screw, a rotating shaft being movably connected to the front of the threaded sleeve via a first bearing, a sliding sleeve being fixedly connected to the front of the rotating shaft, a connecting rod being slidably connected to the inner cavity of the sliding sleeve, a connecting shaft being fixedly connected to the bottom of the back of the connecting rod, a fixed sleeve being fixedly connected to the surface of the connecting shaft, and a cladding head being fixedly connected to the bottom of the fixed sleeve.

[0015] 2. By setting an auxiliary mechanism, the left side of the pipe fitting is engaged with the first cone block. Then, the second electric slide is started, which drives the rectangular block to move. The rectangular block drives the movable shaft to move, and the movable shaft drives the second cone block to move, thus fixing the pipe fitting. The second motor is started, which can drive the first cone block to move. The first cone block drives the pipe fitting to rotate, which facilitates the cladding work.
