The invention belongs to the technical field of cold-rolled strip manufacturing tool, and particularly relates to a chamfering and
grinding device for a disc-
cutting edge. The chamfering and grindingdevice comprises a support platform, a support vertical plate, a driving device, a
cutting edge piece rotation motion transmission device and a
grinding head reciprocating
linear motion transmission device, wherein the
cutting edge piece rotation motion transmission device comprises an upper transmission wheel, an upper transmission shaft, a cutting edge tray, a cutting edge piece, a pressure cover component and an upper bearing component; the
grinding head reciprocating
linear motion transmission device comprises a lower transmission wheel, a lower transmission shaft, a sliding block rotatingdisc, an eccentric shaft, a connecting rod transmission mechanism I, a connecting rod transmission mechanism II and a lower bearing component; and each of the connecting rod transmission mechanism Iand the connecting rod transmission mechanism II is connected with the cutting edge piece. According to the chamfering and grinding device for the disc-cutting edge, the two types of motion, namely the rotation motion and the
linear motion are realized by adopting the same driving device, all the components adopt an adjustable assembling method, the design and the structure are simple, the
assembly and debugging are simple and easy, the requirement on the manufacturing precision is not too high, the
processing difficulty and cost of the equipment are reduced, and the utilization ratio and production efficiency of the equipment are improved.
