Apparatus and method for machining gas turbine diffuser

Abstract

The invention discloses an apparatus and method for machining a gas turbine diffuser. The apparatus comprises a first fixture, wherein the first fixture comprises a first chassis, a positioning pin and a connecting bolt. By adopting the technical scheme, the apparatus and the method have the beneficial effects: the difficulty in machining workpiece is solved; by adopting the apparatus, the clamping and centering of the workpiece are realized, and the dimension precision at various positions of the workpiece can be controlled within 0.01mm; and moreover, the machining process is simple and easy to operate.

Description

technical field

[0001] The invention relates to a device and method for processing gas turbine diffusers, which are used for processing gas turbine diffusers (diffusers) with similar shapes and different models. Background technique

[0002] The gas turbine diffuser (diffuser) is mostly a combined cylinder. The thickness and size of the workpiece are different, and it is easy to produce deformation in an unpredictable direction during the processing. In addition, the processing content of the diffuser covers all parts of the body, which brings great difficulty to the clamping of the workpiece.

[0003] In order to ensure the precision of the workpiece processing, simplify the operation, and solve the deformation problem of the workpiece during processing, we have designed a diffuser processing device and method. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide a gas turbine diffuser processing device that can im...

Examples

Embodiment Construction

[0036] Examples such as Figure 1-4 As shown, the gas turbine diffuser processing device includes a first tooling and a second tooling. The first tooling is composed of a first chassis 1, a positioning pin 3 and a connecting bolt 2; the positioning pin 3 and the connecting bolt 2 are arranged on the first chassis 1 on the disk.

[0037] There are two positioning pins 3 and two connecting bolts 2 respectively.

[0038] Each part of the workpiece M is connected by two positioning pins 3 and two connecting bolts 2 to ensure reliable positioning and connection.

[0039] The second tooling is composed of a second chassis 4, an inner tank 5, a plurality of first fixing blocks 6, a plurality of second fixing blocks 7, and fixing bolts.

[0040] The second chassis 4 is disc-shaped, and the disk surface of the second chassis 4 is integrally connected with an annular seat 11, the annular seat 11 is coaxially arranged with the second chassis 4, and the inner bag 5 is fixedly connected ...
