Furthermore, a reinforcing groove which is concave in a ring shape is formed in the length direction of the knife post positioning sleeve for the positioning pin to pass through.
The strength of the perforation is improved, and the cutter can be used as a positioning line of the end part of the cutter positioned in the cutter post positioning sleeve.
Further, two positioning pins located in the tool post positioning sleeve elastically fix the end of the tool.
So that the cutter can be replaced according to the specification of the product.
Further, the diameter of the knife column positioning sleeve is the same as that of the product.
Has the advantages that: compared with the prior art, the utility model:
adopt the design scheme of the utility model, can be by the centre gripping of dorsad shaft chuck to stretch into the product hole, process burr and chamfer in the product hole, reduce the burr rate of product.
