Description
Technical Field
The utility model relates to a clamping tool for a cylindrical part with a key groove on the inner wall, and belongs to the technical field of machining processes.
Background
The part to be processed is a cylindrical part, a key groove is processed in the inner wall of one end part of the part, a positioning key extending axially is processed in the inner wall of the other end of the part, and a certain phase angle relation exists between the positioning key and the key groove. When the part is machined by the traditional process, the positioning key machining procedure at the other end is difficult to position and machine after one end of the key groove is finished, and machining can be possibly realized through changing the process sequence and the clamping mode, so that the procedure is increased, the difficulty is increased, the time and the labor are wasted, and the machining is realized without a simpler and feasible method. By adopting the tool for application, various factors are integrated, the complex operation can be simplified, the processing efficiency is improved, and the processing difficulty is reduced.
