Description

Milling cutter with chamfering function Technical Field The utility model relates to the technical field of milling cutters, in particular to a milling cutter with a chamfering function. Background At present, the chamfering milling cutter is a milling cutter specially used for chamfering, the shape and the angle of a cutting edge of the chamfering milling cutter are specially designed, and the chamfering milling cutter with single angle and the chamfering milling cutter with double angles are common. The double-angle chamfering milling cutter can be used for simultaneously processing two chamfers with different angles, is suitable for special chamfering requirements, and needs to be replaced according to the chamfers with different angles when the part is subjected to chamfering processing. However, most of the existing chamfer milling cutters are of an integrated structure, the integrated chamfer milling cutters need to be integrally disassembled when being replaced, fixing screws or clamps need to be unscrewed by means of special tools, the operation steps are more and time-consuming, when the parts with various chamfer angles are machined, the chamfering angles are switched once, and the old milling cutters, the new milling cutters and the tool setting are required to be stopped, disassembled and the machining efficiency is greatly reduced. Disclosure of utility model In order to solve the technical problems, the utility model provides a milling cutter with a chamfering function. The milling cutter with the chamfering function comprises a cutter bar, wherein one end of the cutter bar is provided with a chamfering milling head used for chamfering, one side of the chamfering milling head is provided with a connecting component connected with the cutter bar, both sides of the cutter bar are provided with fixing components for fixing the connecting component, the connecting component comprises a connecting column fixedly arranged on one side of the chamfering milling head, one end of the cutter bar is provided with a connecting groove, and one end of the connecting column extends to the inside of the connecting groove.
