A universal fixture for self-adaptive clamping of blade tip or blade crown process table

Abstract

The invention relates to a universal fixture of a self-adaptive clamping blade tip or blade crown technology table. The universal fixture of the self-adaptive clamping blade tip or blade crown technology table comprises a pair of movable blocks, an adjustable positioning rod, a pair of combined fixed blocks, two locking rings, a positioning block, a limiting block, a base, two cylindrical bearingsand a bottom plate. According to the universal fixture of the self-adaptive clamping blade tip or blade crown technology table, the combined fixed blocks and the base are separated, when a blade tipis directly clamped on the fixture, after the blade tip is clamped, the combined fixed blocks and the base can slide mutually, so that the universal fixture further performs certain float after clamping the blade tip, self-adaptive clamping of parts is realized, and possible clamping stress is reduced. Meanwhile, according to the universal fixture of the self-adaptive clamping blade tip or blade crown technology table, a blade is directly clamped on the fixture, positioning is carried out without adopting a center hole. Finally, according to the universal fixture of the self-adaptive clampingblade tip or blade crown technology table, the universal fixture can directly clamp the blade tip by using a mode of the adjustable positioning rod being matched with the locking rings.

Description

technical field [0001] The invention belongs to the field of fixtures, in particular to a universal fixture for self-adaptively clamping a blade tip or a blade crown process table Background technique [0002] At present, the blade tip fixtures for blade profile processing all use the method of positioning and clamping the top hole of single-drive equipment or the positioning and clamping of the top hole of double-drive equipment. There are two following disadvantages in this method: 1. The tightness will lead to a large clamping stress of the part during the processing process, which will lead to the stress release and deformation of the part after the processing is completed; 2. Regardless of single drive or double drive, the center hole is used for positioning, the size and position of the center hole determine the The qualified rate of blade profile processing, however, there will be deformation after rough machining and heat treatment of most parts, resulting in unquali...
