Hardness testing device for castings

Abstract

The utility model discloses a kind of hardness detection devices for castings, it is related to castings detection technical field, including workbench, the bottom center position of the workbench is fixedly installed with servo motor, the output shaft of the servo motor is through the bottom side inner wall of the workbench and fixedly installed with pivot, the top of the pivot is fixedly installed with clamping mechanism, the both sides inner wall of the workbench is fixedly installed with mounting plate, the top of the mounting plate is equipped with first ball hole. In the utility model, when the castings need to have camber, it can be stretched by starting adjusting cylinder, adjusting cylinder's movable end drives fixed plate to move, fixed plate moves so that upper rotating ball rotates in second ball hole, simultaneously makes that slide bar slides in slide hole, and then makes that lower rotating ball rotates in first ball hole, and then makes that detection cylinder and hardness detector rotate, to meet the castings with camber to detect.
