Abstract

The invention relates to a fixing tool for turbine blade machining, and belongs to the technical field of aero-engine manufacturing. The fixing tool comprises a bottom plate, a chuck, a transverse self-adaptive adjustment supporting assembly and a longitudinal self-adaptive adjustment supporting assembly; the chuck is used for clamping tenon teeth and is fixedly connected to one end of the bottomplate; the transverse self-adaptive adjustment supporting assembly is used for supporting the blade back of a blade, the transverse self-adaptive adjustment supporting assembly is fixedly connected toone side of the other end of the bottom plate, and the output end of the transverse self-adaptive adjustment supporting assembly abuts against the blade back; and the longitudinal self-adaptive adjustment supporting assembly is used for supporting the shroud of the blade, the longitudinal self-adaptive adjustment supporting assembly is fixedly connected to the other side of the other end of the bottom plate, and the output end of the longitudinal self-adaptive adjustment supporting assembly makes contact with the shroud. The fixing tool can well fix the turbine blade, the reliability of machining quality is improved, operation is convenient, and the labor intensity of an operator can be relieved.

Description

technical field

[0001] The invention belongs to the technical field of aero-engine manufacturing, and in particular relates to a fixed tool for machining turbine blades. Background technique

[0002] The turbine blade used on the aero-engine includes a blade body and a connecting head. The connecting head has double teeth and a tenon. One end of the blade body is integrally formed with the tenon. The blade body includes a blade crown and a blade back. Since the turbine blade is used in the field of aviation technology, high machining accuracy is required, so the turbine blade needs to be fixed during processing.

[0003] The currently adopted turbine blade fixing method is to set a tooth vortex on the back of the tenon teeth, set a point on the back of the blade body, and set a point on the exhaust side of the blade crown. A tooth vortex is set in the direction of the mortise-tooth basin, and is pressed with a pressure plate, and the direction of the air inlet edge of the b...

Embodiment

[0040] Such as Figure 1-Figure 4 As shown, this embodiment provides a fixed tool for turbine blade processing, including: a base plate 1, a chuck, a lateral self-adaptive adjustment support assembly and a longitudinal self-adaptive adjustment support assembly.

[0041] The collet is used to clamp the mortise, and the collet is fixedly connected to one end of the bottom plate 1 . The lateral adaptive adjustment support assembly is used to support the back of the blade. The lateral adaptive adjustment support assembly is fixedly connected to one side of the other end of the bottom plate 1 , and the output end of the lateral adaptive adjustment support assembly abuts against the blade back. The longitudinal self-adaptive adjustment support assembly is used to support the blade shroud of the blade. The longitudinal self-adaptive adjustment support assembly is fixedly connected to the other side of the other end of the bottom plate 1, and the output end of the longitudinal self-ad...
