Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a novel cutting and grinding milling cutter. Background Art

[0002] Milling cutters are cutting tools commonly used in milling machines or processing machines to perform milling operations (sometimes in other machine tools). They remove material through their fixed feed rate within the machine. Milling cutters have several shapes and many sizes, and can also choose coatings as well as helix angles and the number of cutting faces. After the workpiece is processed with a milling cutter, since the milling surface is relatively rough, it is necessary to replace the milling cutter with a grinding head to grind the milling surface or transfer the workpiece to a grinding station to grind the milling surface. The operation is cumbersome and reduces the processing efficiency. Therefore, a new type of cutting and grinding milling cutter is proposed to facilitate milling and grinding processing. Utility Model Content

[0005] By adopting the above technical solution, the nut on the connecting bolt is unscrewed, the tool rod is slid vertically, the end of the connecting bolt is passed through the through slot on the tool rod and the nut is tightened, the distance between the cutter head and the connecting sleeve can be adjusted as needed, and after the workpiece is milled using the cutter head, the workpiece can be polished using the rotating polishing sleeve, the threaded sleeve is loosened, the distance between the polishing sleeve and the connecting sleeve is adjusted, and then the threaded sleeve is tightened, and the position of the polishing sleeve relative to the cutter head can be adjusted as needed, and there is no need to replace the milling cutter with a polishing head to polish the milling surface or transfer the workpiece to the polishing station to polish the milling surface, thereby improving the processing efficiency.

[0006] Specifically, the connecting sleeve is provided with two connecting holes, and the two connecting holes are both located above the connecting bolts.

[0007] By adopting the above technical solution, the setting of the connecting hole is conducive to the passage of the bolt, and it is convenient to connect the connecting sleeve with the driving device by bolts.

[0008] Specifically, a flange is integrally formed on the outer wall of the connecting sleeve, the flange is located between the connecting bolt and the polishing sleeve, and a protective cover is rotatably connected to the flange.

[0009] By adopting the above technical solution, the flange and the protective cover can block the debris generated during the milling and grinding process, thereby protecting the driving components of the milling machine. The flange is rotatably connected to the protective cover. During the rotation of the connecting sleeve, the protective cover does not maintain synchronous high-speed rotation with the connecting sleeve, so that the debris is not easily thrown out to disrupt the working environment.

[0012] Specifically, a plurality of anti-slip protrusions are fixed on the outer wall of each threaded sleeve.

[0013] By adopting the above technical solution and setting the anti-skid protrusion, it is convenient to rotate the threaded sleeve.

[0014] Specifically, the bottom end of the grinding sleeve is configured to be conical.

[0015] By adopting the above technical solution, the bottom end of the grinding sleeve is set to be conical, which can adapt to holes with larger diameters on the workpiece.

The flange 80 is rotatably connected to the protective cover 5. During the rotation of the connecting sleeve 8, the protective cover 5 does not maintain a synchronous high-speed rotation with the connecting sleeve 8, so that the debris is not easily thrown out to disrupt the working environment.
