Grinding clamp suitable for turbine multi-connected guide vane part assembly

Abstract

The grinding clamp suitable for the turbine multi-connection guide vane part assembly can be used for clamping the turbine multi-connection guide vane part assembly, clamping is convenient, stability is high, and the clamping rigidity of vanes can be enhanced. The device comprises a mounting bottom plate, and a positioning mechanism, a supporting mechanism and a pressing mechanism are mounted on the mounting bottom plate; the positioning mechanism comprises a blade positioning block and a blade outer ring runner surface clamp positioning block, and the top of the blade positioning block protrudes upwards to form a positioning boss I and a positioning boss II; the supporting mechanism comprises a first supporting structure and a second supporting structure, the first supporting structure corresponds to the bottoms of the inner ring and the outer ring of the part, and the second supporting structure is used for supporting the inner radial face of the part. The pressing mechanism comprises a first pressing structure, a second pressing structure and a third pressing structure. The first pressing structure is used for pressing an outer ring of a part, the second pressing structure is used for pressing an inner ring of the part, and the third pressing structure is used for being matched with a blade outer ring runner face clamp positioning block to clamp the outer ring runner face of the part.

Description

technical field [0001] The invention relates to the technical field of grinding jigs, in particular to a grinding jig adapted to the component assembly of turbine multi-connected guide vanes. Background technique [0002] Such as figure 1 The design of the turbine multi-connected guide vane parts assembly shown has the characteristics of large volume, complex structure, and large-area thin-walled structure. For the blank, advanced technologies such as precision forging, ultra-speed forming and diffusion connection technology, and additive manufacturing technology are usually used. When the blade is ground, the blade is clamped on the fixture and is easily deformed by the clamping stress. Processing Tool vibration is easy to occur during the process, so it is necessary to design a fixture for grinding turbine multi-connected guide vane components. Contents of the invention [0003] Aiming at the problem that the turbine multiple guide vane component assembly is easily def...
