A special fixture for heat treatment of rim tension uniformization

Abstract

The utility model discloses a special fixture of steel ring tension homogenization heat treatment belongs to steel ring homogenization heat treatment fixture technical field, and its technical scheme main points include the machining table, the top of machining table is connected with the limiting mechanism of limit stop, and the top swing joint of machining table has the auxiliary mechanism, the limiting mechanism includes the limiting frame, hydraulic cylinder, limit ring, connecting rod, limit stop, limit rod, assembly groove and a plurality of runner, the limiting frame is connected in the top of machining table, and the inner wall of limiting frame is fixedly connected with hydraulic cylinder, can adapt to different diameter, shape's steel ring through setting limiting mechanism, need not frequently replace fixture, simultaneously, the encoder of hydraulic cylinder output end real -time detection telescopic amount, and the accurate control clamping tension of cooperation PLC controller, avoid over -clamp to lead to steel ring deformation or under -clamp to lead to positioning failure, solved the problem that traditional fixture cannot adjust tension flexibly, convenient operation and high precision.
