Abstract

The invention discloses a turbine rotor grinder clamp. The turbine rotor grinder clamp is used for propping blades of a turbine rotor open. The turbine rotor grinder clamp comprises a support assembly, a locating assembly, tightly propping assemblies and a press machine, wherein the support assembly is used for fixing a turbine disk, the locating assembly is in clearance fit with the support assembly and used for tightly pressing the two end faces of the turbine rotor, the tightly propping assemblies are located on the two sides of the turbine disk, abut against the locating assembly and are used for propping the blades of the turbine rotor to the maximum diameter, and the press machine is used for applying press force so as to enable the tightly propping assemblies to prop the blades of the turbine rotor open. The support assembly and the locating assembly fix the turbine disk and tightly press the end faces of the turbine rotor, and the press machine applies the press force to the tightly propping assemblies so as to enable the tightly propping assemblies to prop the blades of the turbine rotor open to the maximum diameter. The turbine rotor grinder clamp effectively solves the technical problem that when the turbine rotor is ground on an ordinary machine tool, because the blades of the rotor cannot be opened to the maximum diameter, some blades cannot be ground.

Description

technical field [0001] The invention relates to the field of engine assembly, in particular to a grinding fixture for a turbine rotor. Background technique [0002] Before the engine gas turbine rotor is assembled to the engine, the entire blade tip needs to be ground. The diameter of the grinding is the maximum diameter φD of the blade rotating at high speed in the engine. At present, the end teeth of the engine gas turbine rotor are mainly fixed. On the end teeth of the grinder jig, use the tie rod, pressure plate, washer, and nut to tighten the gas turbine rotor, put the grinder jig with the gas turbine rotor on the grinder, and use the double tip of the grinder to withstand the center holes at both ends of the tie rod. The machine tool starts to rotate, and the tip of the blade is thrown out of the maximum diameter φD by the centrifugal force of the machine tool rotation, and the grinding wheel of the grinder starts to grind the tip of the blade after the grinding diamet...
