In various mechanical processing fields, such as automobile manufacturing, aerospace, mold processing, etc., tools that can adapt to different materials, different shapes and different processing technologies are needed to meet the processing needs of complex parts.

[0003] After the existing workpieces are produced, the outer surface needs to be processed and cleaned. The current production practice requires a large number of people to use manual mechanical tools or grinding wheels for processing and cleaning. This not only causes a waste of resources and low work efficiency, but also generates a lot of dust and splashing of high-temperature granular materials during the processing process, which poses a great threat to the personal health of the operators. Therefore, a fully adaptable tool for combined processing is needed to solve the above problems. Utility Model Content

The second chain performs arc surface processing through the centrifugal force generated by the rotation of the chain main shaft.

[0008] As a preferred embodiment, the second swing chain processes the arc-shaped outer surface of the workpiece through the centrifugal force generated by the rotation of the swing chain main shaft.

[0009] As a preferred embodiment, a flat knife is provided at the left end of the flat knife main shaft, and the flat knife is connected to the main reducer through a gear plate and the flat knife main shaft. A gear plate is provided on the left side of the flat knife connecting plate, and a first gear is provided in the middle position inside the gear plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model has a bowl cutter with a certain deflection and up and down movement on the bowl cutter main shaft through the expansion and contraction of the spring. The bowl cutter has a certain flexibility and will not cause damage to the workpiece during processing. The outer cylindrical surface of the bowl cutter is connected to a plurality of flexible first swing chains, which can be used to process bowl-shaped and hole-shaped inner surfaces. At the same time, the relative position with the workpiece can be adjusted to process bowl-shaped and hole-shaped inner surfaces of different sizes.

[0013] This utility model features a flat cutter fixed to the left end of the flat cutter spindle via a gear disc. When machining the workpiece surface, the cutter adjusts itself to the workpiece surface as the plane deforms, adjusting itself through the expansion and contraction of the cylinder, ensuring that the cutter always remains in close contact with the workpiece surface. Furthermore, the meshing of several intermeshing cutter discs ensures the integrity of the machined surface. This adaptability to various object shapes eliminates the need for tool replacement and adjustment, significantly saving labor costs, significantly improving production efficiency, reducing operating costs, and minimizing the risk of dust to personnel. This addresses a shortage of cutting tools in the industry. When installed on a robotic arm, the machine can perform all-around, fully adaptive automatic machining of castings and carbon calcined bodies. It can handle combined machining, grinding, and slag removal of flat surfaces, right angles, chamfers, concave and convex surfaces of various curvatures, holes with diameters above a specified diameter, bowl shapes, and combinations of these three-dimensional shapes.
