Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, and more specifically, to a PCD milling cutter with adjustable angle. Background Art

[0002] PCD milling cutters, with their excellent hardness, high thermal conductivity, low coefficient of thermal expansion, and extremely sharp cutting edges, have shown great potential and advantages in the high-speed cutting and machining of non-metallic and non-ferrous metal materials.

[0003] Chinese Patent CN220761126U discloses a structure of a multi-edge PCD milling cutter with adjustable cutter head angle. This mechanism realizes meshing connection through the outer edge of a gear and a toothed disc. A connecting rod is arranged above the toothed disc. When the gear rotates under the action of driving force, its movement is converted into the rotation of the connecting rod and the milling cutter head thereon through the toothed disc, enabling the cutter head to adjust its angle within a certain range around the central inner hole of the milling cutter. Although this adjustment process can change the circumferential position of the cutter head, it does not change the inclination or deflection angle of the cutter head relative to the inner hole of the milling cutter, that is, it maintains the original geometric features and working postures of the cutter head and does not directly adjust the attack angle of the cutting edge. Summary of the Utility Model

A manual adjustment mechanism is provided inside the PCD milling cutter body, and the manual adjustment mechanism can drive the rotating wheel to rotate.

[0007] Further, the manual adjustment mechanism includes a fixed ring. A moving block is slidably matched on the fixed ring. A steel wire rope is wound around the outside of the fixed ring. The steel wire rope passes through the rotating wheel and is locked and fixed by a buckle. The moving block is fixedly connected to the steel wire rope.

[0008] Further, an arc-shaped slot is provided on the top plate. An arc-shaped screw is installed in the arc-shaped slot. An arc-shaped through hole matched with the arc-shaped screw is provided on the moving block. The moving block can move along the arc-shaped screw.
