Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a split milling cutter structure. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the excess of the workpiece intermittently in sequence. The milling cutter is mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines. When optimizing the milling effect, the milling cutter blade is another important factor. If more than one blade participates in cutting at any time, it is an advantage, but too many blades participate in cutting at the same time is a disadvantage. During cutting, each cutting edge cannot cut at the same time. The required power is related to the number of cutting edges participating in cutting.

[0003] The existing publication number CN213560143U discloses a split combined milling cutter structure, including a milling cutter column, a chip retracting groove, milling teeth, a fixed base, a slot, a locking hole, a water inlet, a milling cutter connector, a cleaning liquid nozzle, a milling cutter slot, a screw hole, a milling cutter, a docking hole, a fixing plate and a fastening screw; the milling cutter slots are symmetrically arranged with four, and form a four-leaf clover-shaped structure. Through the four-leaf clover-shaped symmetrical structure, the efficiency of the milling cutter structure can be maximized during milling. The milling cutter passes through the fixing plate through the fastening screws and is screwed and locked with the screw hole, and then is replaceably connected to the milling cutter slot.

[0004] In summary, the milling cutter in the prior art is generally a columnar structure. For the processing of stepped products, the columnar structure needs to add an additional process to achieve it; it increases the processing time, resulting in relatively low production efficiency. For this reason, we propose a split milling cutter structure. Utility Model Content
