Grinding machine angle adjusting device

The utility model discloses a grinding machine angle adjusting device which comprises a supporting rotary disc used for supporting, a limiting device used for limiting is arranged at the center of the upper end face of the supporting rotary disc, and a transmission worm gear is fixedly arranged at the center of the lower end face of the limiting device. And two groups of limiting clamping seats are arranged on the lower end surface, close to the transmission worm gear, of the supporting turntable. By arranging the machining device and the limiting device, when the angle of the grinding machine is precisely regulated and controlled, the gear motor can drive the transmission worm to rotate, the transmission worm can drive the transmission worm gear to rotate in a meshed mode, and then the positioning angle of a machining tool is precisely regulated and controlled; and meanwhile, the servo motor can drive the two sets of inserting clamping plates to be limited into the limiting clamping grooves through the two-w
