Description

Technical Field

[0001] The invention relates to the technical field of milling cutter discs, and in particular to a milling cutter disc. Background Art

[0002] Milling refers to a processing method of cutting workpieces using a rotating multi-blade tool. The milling cutter includes a cutter disc and multiple blades. The cutter disc is mostly a disc-shaped structure. The blades are fixedly arranged on the circumference of the cutter disc, and the blades are mostly installed vertically to form a milling surface on the side of the cutter disc. When the cutter disc rotates one circle, multiple blades will participate in milling. If the cutting amount of each blade is different on the rotating circle, severe radial vibration will occur, affecting the milling accuracy and blade life; the radial extension distance of the blades on the existing milling cutter disc cannot be adjusted, which is not suitable for deep excavation milling in a narrow space at the junction of two surfaces, and cannot complete root milling. On the other hand, the blade adjustment position of the existing milling cutter disc is mostly adjusted individually one by one, and the radial extension distance of multiple blades is small and there are differences, which is easy to affect the milling depth and accuracy. Therefore, we designed a milling cutter disc.

[0003] Patent No. CN201520321811.1 is a Chinese utility model patent, which discloses a drilling and milling cutter disc, including a drilling and milling cutter disc body, a blade slot is provided on the drilling and milling cutter disc body, and a blade is installed on the blade slot. It is characterized in that a drill bit is provided at the center position of the drilling and milling cutter disc body; the utility model installs the drill bit at the center position of the drilling and milling cutter disc body, so that the two sets of processes of drilling and milling can be completed in one go. In addition, the drill bit and the drilling and milling cutter disc body have a detachable structure, which is convenient for replacing drill bits of different diameters; the standard triangular blade is used, so that the tool does not need to be customized, and the triangular blade can be used alternately on three sides, thereby greatly reducing the cost of using the tool. However, the utility model has the following problems: first, the radial extension distance of the blade on the milling cutter disc cannot be adjusted, and it is not suitable for deep excavation and milling in a narrow space at the junction of two surfaces, and root milling cannot be completed; secondly, the clamping of the blade is not stable enough, and the blade is prone to shifting during high-speed rotation. The radial extension distances of multiple blades are small and there are differences, which can easily affect the milling depth and accuracy. Summary of the invention
