Abstract

The invention relates to a deep hole compound bore rolling head that has bore identity at left, connecting cutting tool in the middle and joint at right. The jogger is installed in the middle of connecting blade and big piston. Rollers are distributed around connecting cutter body on the right of bore identity. The right side of connecting cutter body has supporting disc installing on jogger. Bit piston is on the right side of supporting disc, and direction guiding block is installed on the joint outer circle. The rapid oil joint is installed in the joint. The upper and down half finish boring knife is installed on the left of bore identity. Two rectangle finish boring knife is installed on the left bore identity. The structure could make the efficiency to be 3-5 times of traditional deep hole machining cutting tools. And it has the advantages of high accuracy, high stability, compact structure, etc.

Description

Technical field [0001] The invention relates to a special cutting tool for deep hole processing, in particular to a deep hole combined boring and rolling head. Background technique [0002] At present, the original deep hole machining requires a variety of tools such as semi-finish boring, fine boring, and rolling head. The number of tools is large, and the replacement of tools and guide sleeves is time-consuming, laborious and complicated, and the work efficiency is low. Contents of the invention [0003] In order to overcome the problems existing in the existing boring tools for deep hole machining, the present invention provides a new combination boring and rolling head for deep holes, which organically combines the functions of the tools in each process into one body, and can realize the automatic expansion and contraction function of the tool and the roller , making the operation more convenient and saving auxiliary time. [0004] The technical solution adopted by th...
