Automatic spraying device for large wind power products

Abstract

An automated spraying device for a large wind power product comprises spray guns, spray gun action drawing mechanisms, a workpiece action drawing mechanism, a field air purifying system and a control system, wherein the spray gun action drawing mechanisms are positioned beside the workpiece action drawing mechanism; an air suction opening of the field air purifying system faces the spray gun action drawing mechanisms; the workpiece action drawing mechanism comprises a fixed base, a working table and a jig bottom plate; the working table is slidably connected to the fixed base; the jig bottom plate is detachably connected to the working table; a spray gun supporting track of each spray gun action drawing mechanism is slidably connected with a vertical track; the bottom end of the vertical track is slidably connected with a ground track; each spray gun supporting track is slidably connected with a corresponding spray gun supporting mechanism; a head end of a fixed section of each spray gun supporting mechanism is connected with the tail end of a corresponding first moving section through two rotating shafts which are perpendicular to each other; the head end of each first moving section is connected with the tail end of a corresponding second moving section through two rotating shafts which are perpendicular to each other; the head end of each second moving section is connected with the corresponding spray gun; and the control system controls action of the various rotating shafts.

Description

Technical field [0001] The technical solution belongs to the technical field of mechanical processing, and is specifically an automatic spraying device for large-scale wind power products. Background technique [0002] The technical status of spraying (painting or zinc spraying, etc.) for large workpieces is that large workpieces (such as certain wind turbine nacelle components, whose shapes are irregular and complex, and some workpieces also need to be sprayed on the wall of the cavity. Larger size The widest part reaches more than 5 meters, and the weight of a single piece reaches about 50 tons.) It needs to be painted manually by paint workers. The manual spraying method is inconvenient to work, and the pollution generated during the spraying process will cause great harm to the operators. For the spraying of this type of workpiece, automated spraying is a trend. However, the working surface of complex shape and spraying is also very complicated. If the volume and quality of...
