Abstract

The invention relates to a tool assembly for machining inner spherical surfaces. The tool assembly is characterized in that a supporting seat is fixed on a central supporting plate in the front of a lathe square tool post, and a guide rod is fixed in an inner hole of the supporting seat. A tool sleeve is fixed at the front end of the guide rod through a hinge pin I and is connected with a sliding threaded sleeve through a connection rod, and the connection rod is connected with the tool sleeve through a hinge pin II. A tool body is fixed in the tool sleeve through a screw, a threaded rod is screwed in the sliding threaded sleeve, and a handle is connected with the end of the threaded rod. The tool assembly has the advantages of being accurate in spherical center location, suitable for being produced in batch, simple in structure, easy to operate and capable of not affecting other machining processes.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a tool assembly for processing inner spherical surfaces. Background technique [0002] In the production of differential housings for agricultural transport vehicles, the inner spherical surface must be processed, among which the inner spherical surface is required to be IT8 grade, the coaxiality of the spherical center and the Guanjian hole and shaft is Ф0.04mm, and the surface roughness is Ra3 .2 μm. Due to the restrictive conditions, it is difficult to carry out fine processing. Small tool holders are often used to process inner spherical surfaces on lathes, but it is difficult to ensure the consistency of machining accuracy in mass production, it is difficult to achieve mass production, and the production efficiency is low. Contents of the invention [0003] In view of the above problems, the present invention provides a machining inner spherical tool assembly suit...
