Embodiment
A kind of milling machine cutter head embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
A kind of milling machine cutter head, including cutter hub 1 and 21 2, point of a knife, the point of a knife include 21 20, point of a knife and knife for 21 2
Point 21, the point of a knife 21 include operator point 210 and secondary point of a knife 211, and 21 20, the point of a knife is in round table-like setting, and cross section is by knife
The direction of body 1 is gradually successively decreased towards the direction of point of a knife 21, the rounded setting in cross section of the operator point 210 and secondary point of a knife 211, and
Cross section is gradually successively decreased by bottom towards end, and the bottom of the operator point 210 and secondary point of a knife 211 is equipped with to be adapted with end
Neck 212, the operator point 210 and secondary point of a knife 211 are arranged in groove 200 successively, wherein operator point 210 extends groove
Outside 200, the end of secondary point of a knife 211 is arranged in the neck 212 of operator point 210, the inwall of described counter conductor one end of groove 200
Internal thread is provided with, the outside of cutter hub 1 is provided with the external screw thread being adapted, and the cutter hub 1 is fitted through located at groove by screw thread
In 200, and it is inconsistent with the bottom of secondary cutter hub 1.The cutter hub 1 is mounted opposite on one end in 21 20 grooves 200 of point of a knife
Provided with mounting groove 10, the size of mounting groove 10 is adapted with the bottom size of operator point 210, secondary point of a knife 211, the mounting groove
