Cutter bar reinforcing device

The utility model discloses a cutter bar reinforcing device and relates to the field of cutter machining. The utility model aims to solve the problems that a cutter in the prior art is extremely easyto vibrate when processing an inner hole of a long shaft of a turbine; therefore, the surface roughness of the inner hole of the turbine long shaft is poor. The device mainly comprises a main body andM bolts, main body is a cylinder, the end surface of the column body is oval; a kerf is formed in one side of a long axis in the end face ellipse of the main body along the length direction of the main body; a first through hole is formed in the other side close to the long axis of the end face ellipse of the body in the length direction of the body. The first through holes and the kerfs are communicated, M second through holes and M first threaded holes are formed in the positions, on the two sides of the kerfs, of the outer circle face of the body at equal intervals, each bolt is arranged in the corresponding first
