Continuous grinding and machining device for threaded blade of spinal orthopedic support

The utility model relates to the field of blade machining, in particular to a continuous grinding and machining device for a spinal orthopedic support threaded blade. According to the scheme that the rotating disc drives the threaded blade body to continuously rotate and grind, and meanwhile the rotating disc is positioned, the threaded blade grinding device has the beneficial effects that the threaded blade body is placed in the gap between the fixing block and the pressing rod, then the pressing rod is rotated, one end of the pressing rod tightly presses the threaded blade body, and the threaded blade body is clamped in the fixing block; then the threaded blade body is fixed, a second motor drives a rotary disc to rotate, the threaded blade body is driven to move, when the threaded blade body reaches the position below a grinding plate, a hydraulic cylinder drives a first motor to move downwards, then the first motor drives the grinding plate to rotate, and the threaded blade body is ground; and the air cyl
