Disk, the connector and the positioning disk, which are integrally formed, to be made, in the central axis of the cutter head mounting disc, the connector
On the same line, the connector is divergent-cone wall to the central axis of mandrel line and the positioning disk, and the positioning disk is
Ring-shaped structure, the outer circumference surface of the positioning disk is integrally formed with the connector and connects, in the circle centre position of the positioning disk
Axis hole is provided with, the axis hole is circular through hole, and multiple cooling holes are uniformly provided on the connector；
Multiple cutter head connectors are evenly arranged in the left side of the cutter head mounting disc, each cutter head connector packet
Include the groove for being opened in the cutter head mounting disc left side and multiple thorn-like protrusions being arranged on each groove slot bottom, Mei Gesuo
Described thorn-like protrusion for stating cutter head connector is uniformly distributed on the slot bottom of the groove, the institute of each cutter head connector
Piece thorn-like protrusion is stated to increase from the bottom portion of groove spiral.
The cooling hole is water-drop-shaped through-hole or ellipse hole.
The groove is circular groove.
The internal diameter of the connector left end is more than the internal diameter of its right end.
The quantitative range of piece thorn-like protrusion on each groove slot bottom is 2 ~ 4.
The cutter head connector is scattered in a circumference or multiple concentric circles.
The utility model includes cutter head mounting disc, connector and positioning disk, is uniformly arranged in the left side of cutter head mounting disc
There are multiple cutter head connectors, each cutter head connector includes being opened in the groove of cutter head mounting disc left side and is arranged on each groove
Multiple thorn-like protrusions on slot bottom, the piece thorn-like protrusion of each cutter head connector are uniformly distributed on the slot bottom of the groove,
Described thorn-like protrusion of each cutter head connector is increased from the bottom portion of groove spiral..Mill is in pressing process, knife
Head can firmly wrap sheet thorn-like it is raised, by the groove of the carcass powder packed of cutter head to cutter head connector, tire after sintering
Piece thorn-like protrusion in the groove of body powder powder and cutter head connector links into an integrated entity structure, and piece thorn-like protrusion is through cutter head
With the junction of grinding disc substrate, the huge shearing force generated during mill work can be resisted, can be prevented golden when mill rotates
Diamond tool bit comes off.
The utility model is simple in structure, not only improved mill compacting working efficiency, but also improve sintered cutter head with
The bonding strength of matrix.In addition, the utility model also has the advantage of structure beauty, i.e. cutter head mounting disc right side is smooth without recessed
Hole.

Specific embodiment
As depicted in figs. 1 and 2, the utility model includes circular cutter head mounting disc 1, the inner circle with cutter head mounting disc 1
Connector 5 that is that circumferential surface connects and being arranged on 1 right side of cutter head mounting disc and the positioning disk 2 being connect with 5 right end of connector, cutter head peace
Sabot 1, connector 5 and positioning disk 2, which are integrally formed, to be made, the central axis of cutter head mounting disc 1, the central axis of connector 5 with
On the same line, connector 5 is divergent-cone wall to the central axis of positioning disk 2, and the internal diameter of 5 left end of connector is more than its right end
Internal diameter, the internal diameter of 5 left end of connector is slightly less than 2 times of its right end internal diameter.Positioning disk 2 is ring-shaped structure, positioning disk 2 it is outer
Periphery is integrally formed with connector 5 and connects, and is provided with axis hole 3 in the circle centre position of positioning disk 2, axis hole 3 is circular through hole, is being connected
Multiple cooling holes 4 are uniformly provided on part 5, cooling hole 4 is water-drop-shaped through-hole or ellipse hole, in the present embodiment, cooling hole 4
