Abstract

The invention belongs to the technical field of parts processing, and in particular relates to a jig and method for laser cutting of aviation titanium alloys, comprising a bottom plate base, at least two fixture positioning parts and at least two part positioning parts; the bottom plate base is provided with a jig and The positioning parts correspond to the fixture positioning holes one by one, and the top of the bottom plate base is provided with profile protrusions for supporting titanium alloy parts, and the profile protrusions are provided with part positioning holes corresponding to the part positioning parts one-to-one. This technical solution can be based on the simple composition structure of the cutting jig, and adopts cast aluminum as the manufacturing material of the cutting jig, which makes the cutting jig lighter in weight and better in strength and fatigue limit; After grinding, it can have a smooth surface structure. Under the conditions of supporting the titanium alloy plate, the convex surface of the profile will not be deformed, and it can also effectively avoid surface quality problems such as scratches on the surface of titanium alloy parts.

Description

technical field

[0001] The invention belongs to the technical field of part processing, and in particular relates to an aviation titanium alloy laser cutting jig and a method. Background technique

[0002] At present, most of the laser cutting of titanium alloys use simple assembly fixtures to clamp the parts. Since the simple assembly fixture does not have a more accurate positioning module and there is no three-dimensional digital model, the positioning coordinate system of laser cutting CNC programming mainly uses the feature points of the titanium alloy digital model for positioning. This positioning method has the following defects:

[0003] 1. Part of the assembled cutting fixture does not have the function of being fixed to the bottom of the machine tool. When the position of the part changes due to special circumstances, the positioning of the part will be inaccurate;

[0004] 2. The part where the simple assembly fixture is in contact with the part rubs against eac...
