Description

Technical Field

[0001] The utility model relates to the technical field of spraying processing of machine tool mechanical arms, in particular to a multi-angle spraying device for machine tool mechanical arms. Background Art

[0002] Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools. Machine tools play a significant role in the modernization of the national economy. They are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tools in mechanical manufacturing and repair factories. There are many types of machine tools, generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. There are many methods for processing mechanical parts in modern mechanical manufacturing. However, all parts with high precision requirements and fine surface roughness requirements generally need to be finally processed by cutting on machine tools. The robotic arms on machine tools are mainly used to improve production efficiency and reduce the risks of manual operation. Their multi-joint design enables them to complete various tasks in plane or three-dimensional space, such as assembly, painting, welding, etc. Through the combination of advanced motors, controllers and sensors, the robotic arms demonstrate efficient and accurate operation capabilities. This technology not only improves work efficiency, but also promotes the automation and intelligent development of industrial manufacturing. The robotic arms on production machine tools require multi-angle spraying, mainly to ensure their surface quality and functional integrity. Spraying is a common surface treatment technology. In the fields of coating, anti-corrosion, waterproofing, etc., during the production process of robotic arms, multi-angle spraying can ensure uniform coating without dead angles, thereby improving the durability and protective performance of the robotic arms. In addition, the complex structure and multi-joint design of the robotic arms also make multi-angle spraying necessary to ensure that each part is fully coated. The current spraying equipment field generally adopts a fixed-angle nozzle design, which shows obvious limitations when spraying multi-sided workpieces. The traditional method requires frequent clamping and flipping of the workpiece to complete the spraying work on different surfaces. This not only greatly increases the complexity of the operation process, but also significantly reduces the overall spraying efficiency. More importantly, when the workpiece surfaces cannot be sprayed simultaneously, the paint may become uneven during the drying process, and in severe cases, it may even cause the paint to fall off. This undoubtedly poses a serious threat to the quality of the products after the robotic arm spraying process. In view of this, we urgently need a new spraying equipment design solution to solve the above problems and improve spraying efficiency and workpiece quality. For the above problems, there may already be technical means to solve them in the existing technology, but this case aims to provide an alternative or replacement technical solution.
