TECHNICAL FIELD

[0001] The utility model relates to a kind of angle milling head coupling devices for boring machine, belong to machine tool processing technical field. BACKGROUND

[0002] Because the ram specification of large numerical control boring machine is relatively large, the angle milling head matched with machine tool is also relatively large, when processing some small space inner cavity, the size of self angle milling head is too large to enter the cavity (for example, each face of inner four square cavity), other small specification angle milling head cannot be connected with the ram of numerical control boring machine. In order to overcome the above-mentioned shortcomings, a device needs to be designed, on the one hand, other small specification angle milling head can be connected with large specification ram, on the other hand, large specification square ram can be transitioned into small diameter connecting body, so that the processing of small size cavity is realized. SUMMARY

[0003] The utility model aims at providing a kind of angle milling head coupling devices for boring machine, to better realize the connection between small specification angle milling head and large specification ram, so that large specification square ram is transitioned into small diameter connecting body.
