Cutting device

Technical Field

The utility model relates to an annex field of lathe especially relates to cutting device.

Background

The bearing bush is a part of the sliding bearing contacted with the journal, the bearing bush is generally made of wear-resistant materials such as bronze, antifriction alloy and the like, the bearing bush made of bronze is a copper bush, a sealing ring is sealed on the copper bush, the abrasion of the copper bush becomes narrow after the copper bush is used for a long time, and the sealing ring with corresponding size and specification needs to be purchased and replaced. The sealing rings with non-standard sizes need to be customized to sealing ring manufacturers independently, the sealing ring manufacturers do not have corresponding matched molds under the common condition, new production molds need to be developed to facilitate production, and the manufacturers usually do not process the sealing rings due to the fact that the ordering quantity is too small.

In addition, in general, after the edge of the sealing ring is damaged, a new sealing ring with the same specification needs to be replaced, so that the use cost is increased, and the sealing ring with the damaged edge still has use value and is not actually further utilized, so that great waste is caused. Therefore, the specification of the seal ring is limited, and the turning tool of the general machine tool is not suitable for cutting the rubber seal ring, so that it is necessary to develop a device which can be clamped on the turning tool of the machine tool and can cut the seal ring.
