Hardness detection equipment for bolt processing

The utility model discloses a hardness detection device for bolt processing, which comprises a hardness detection device, the inside of the hardness detection device is fixedly connected with a fixed box, both sides of the top of the fixed box are provided with sliding ports, and the top of the inner wall of the fixed box is fixedly connected with a limiting ring. And the interior of the limiting ring is movably connected with a rotating rod through a bearing. The bolt is placed on the inner side of the limiting sleeve, the operation block is rotated at the same time, the operation block rotates to drive the worm to rotate, the worm rotates to drive the worm gear to rotate, the worm gear rotates to drive the screw to rotate, the screw rotates to drive the threaded sleeve to move, and the threaded sleeve drives the limiting sleeve to move towards the inner side to clamp the bolt. According to the hardness detection device, detection can be facilitated, the hardness detection device can achieve stable detection
