Abstract
The invention provides a fine-adjustment fine boring unit which comprises a main body, an anti-rotating jack catch, a thread dial and a thread cutter bar. The main body is provided with a stepped inner hole. One end of the stepped inner hole contacts with and is located with a flange end face of the thread dial. The other end of the stepped inner hole contacts with and is located with an axial locating face of the anti-rotating jack catch. The wall of the main body is provided with a through spiral groove which is uniformly arranged along the circumferential direction. The thread dial is provided with a threaded inner hole. An annular deformation groove provided with thin grooves is arranged in an outer cylindrical face far from the flange end face. Pull claws which stretch out along the axial direction and are uniformly arranged along the circumferential direction are arranged on the same side of the axial locating face of the anti-rotating jack catch. The pull claws are located in the stepped inner hole of the main body and are clamped with the side face of the annular deformation groove of the thread dial. The thread cutter bar is connected with the threaded inner hole of the thread dial through threads. The distance between locating faces at two ends of the main body is larger than the sum of the distance between a flange locating face of the thread dial and a clamping side face on the annular deformation groove and the distance between the locating face of the anti-rotating jack catch and a clamping face of each pull claw. The fine-adjustment fine boring unit is simple and reliable in structure, low in manufacturing cost, long in service life, and high in adjusting accuracy.
