Abstract
The utility model provides a composite material boring cutter which comprises a cutter head, a cutter handle and a cutter bar, the annular side face of the cutter head is fixedly sleeved with an installation ring, adjusting columns are installed on the outer sides of a plurality of vertical strips in a sliding mode respectively, round corner blocks are installed at the ends of the adjusting columns respectively, and a plurality of springs are connected with the round corner blocks respectively. The self-locking and cooling device is reasonable in structure and good in practicability, the thermal expansion coefficient difference between the cutter bar and the cutter handle is increased, and therefore the self-locking and cooling device is convenient to disassemble and assemble and has a good self-locking effect and a good cooling effect.
