Abstract

The invention provides a characteristic machining method of an inner cavity of a small machining space based on a three-axis machine tool. The long side of a small elbow is clamped on a main shaft ofthe three-axis machine tool, so that the mounting surface of part equipment is perpendicular to the short side of the elbow, the short edge of the elbow is connected with the rear portion of a cutterbar in a special tool holder tooling through a clamping sleeve, and a cutter disc is used for machining close to a characteristic surface of an inner wall of a part in the small space. During machining of an equipment mounting threaded hole, a punching tool and the part are positioned, a bottom hole drill jig bush is used for machining a bottom hole in the part, and is then replaced with a tappingdrill jig bush for subsequent tapping machining. By means of the characteristic machining method, machining of equipment mounting surfaces in the small machining space can be achieved, machining interference is avoided, and precision is guaranteed; and machining of internal small-space threaded holes can be solved, precision is guaranteed, operation is convenient, and machining cost of the machine tool is reduced.

Description

technical field [0001] The invention belongs to the technical field of part processing, and in particular relates to a method for processing inner cavity features in a small processing space based on a three-axis machine tool. Background technique [0002] Large-sized and small-space parts are in the shape of a long tube with a length of about 700mm. The front and rear openings are "half-moon" in different sizes. The inner cavity has equipment installation surface and hole features, which have higher position and dimensional tolerance requirements, and the feature position is deeper. , some features are close to the inner wall of the part, and the processing space is small. The conventional processing method needs to use the extended tool for processing on the five-axis, but the machine tool spindle is easy to interfere with the inner cavity of the part during the processing process, and the cost of five-axis processing is high. Therefore, in order to realize the processing ...
