Abstract

The invention provides for a clamp for rotation milling machining of a gas compressor blade profile. The clamp for rotation milling machining of the gas compressor blade profile can solve the problems that when a common three-jaw chuck is adopted, blade clamping is not stable, and the machining size is out of tolerance. The clamp for rotation milling machining of the gas compressor blade profile comprises a rotation disk which is fixedly provided with a clamp body; a blade handle portion positioning and clamping assembly is installed on the clamp body and comprises a pressing plate and a positioning base fastened and installed on the clamp body; the positioning base is provided with a V-shaped positioning groove; one outer side end, located on the V-shaped positioning groove, of the positioning base is provided with a supporting block;, and the other outer side end is provided with a locking threaded rod; one end of the pressing plate is movably connected with the supporting block, and the other end of the pressing plate is fastened on the locking threaded rod through a locking nut; an inverted-V-shaped pressing block is arranged at the bottom of the pressing plate; and the inverted-V-shaped pressing block and the V-shaped positioning groove are right opposite to each other in an up-down manner.

Description

technical field [0001] The invention relates to the field of processing fixtures for compressor blades, in particular to a fixture for rotary milling of compressor blade profiles. Background technique [0002] With the continuous development of blade design and research technology, the manufacturing precision of blades is required to be higher and higher, and the traditional blade processing methods are far from meeting the requirements of production efficiency. For the processing of the blade profile of the shank compressor, the traditional fixture structure is to use a three-jaw chuck as the clamp body, and then install a positioning piece on the end surface of the three-jaw chuck, see figure 1 , which uses a positioning member 81 to position the shank of the compressor blade and uses a three-jaw chuck 82 to clamp the outer periphery of the blade shank. Ordinary three-jaw chucks have defects such as poor self-centering effect and insufficient clamping force of the jaws, w...
