Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a thin-walled cylindrical body processing method with densely clustered holes and inclined end surfaces. Through the "complementary" integrated processing of two parts, the waste material during the processing of one part is converted into The main body of another part effectively solves the problem of low material utilization of parts

Embodiment Construction

[0028] Thin-walled cylindrical parts with densely clustered holes and inclined end faces are large in size, and there are hundreds of tiny cooling holes with a diameter of only 1mm distributed on the surface, and the design requires that the arrangement of these holes is symmetrically distributed along the axis of the part, but The number of small holes in each group is uneven. After technological tests, the present invention provides a laser processing method that completes all cooling holes and inclined end faces in one clamping. This process method can solve the problem of difficult alignment and positioning of the inclined end face, and at the same time, realize the one-time clamping processing of the air film group holes and the shape, thereby ensuring the design requirements of the position of the air film hole and the height dimension of the inclined end face.

Abstract

The invention provides a method and clamp for machining a thin-walled cylinder provided with groups of dense holes and oblique end faces. By adoption of the method and clamp for machining the thin-walled cylinder provided with the groups dense holes and the oblique end faces, the problems that the machining efficiency of thinned-walled cylinders provided with groups of dense holes and oblique endfaces which are produced in batches and are of specified models is low, and the material utilization rate is low are solved. Complementary integrated machining of two parts is adopted, namely waste generated when one part is machined is converted into a main body of the other part, so that the problem of the low material utilization rate of the parts is effectively solved; meanwhile, laser machining is used for functional machining in the height direction, so that the problems that oblique end face clamps need to be designed to the parts, and the parts are placed on the oblique end face clampsso as to be machined horizontally are solved; and two times of clamping are replaced by one time of clamping, and two times of alignment are replaced by one time of alignment, so that complex operation by workers is avoided, and the problem that the highest points and the lowest points of the parts cannot be easily aligned is solved.

Description

technical field [0001] The invention belongs to the technical field of special processing, and relates to a processing method and a fixture for a thin-walled cylinder with densely clustered holes and inclined end faces. Background technique [0002] The thin-walled cylinder with densely clustered holes and inclined end faces is a widely used part in a certain type of engine and its derivatives, and a large number of them are processed every year. The original processing technology is to cut the beveled edge at one end of the welded straight blank, and process the cooling air film hole parallel to the beveled edge, and cut the cooling hole parallel to the straight edge at the other end. The specific processing method is: place the part obliquely on the fixture, and make the end face the same as the horizontal angle of the oblique end face of the part. With this placement, a highly consistent horizontal datum can be transformed into a slanted datum. The laser cuts the end fa...
