Emery wheel diameter real -time detection device

The utility model relates to an emery wheel diameter real -time detection device, including fixed plate, detection device support, ultrasonic range measurement device, cylinder, constant pressure valve, benchmark board, emery wheel, fixed plate fixed connection on the lateral wall of the equipment of polishing, ultrasonic range measurement unit bit in fixed plate top, cylinder fixed connection isin the fixed plate bottom, benchmark board fixed connection is on the piston rod. The utility model discloses with the fixed plate direct mount inside the equipment of polishing, can carry out real -time detection to the diameter of emery wheel, and need not to stop production and measure, shortened repair time greatly, improved production efficiency, the ultrasonic range measurement device detects the diameter of emery wheel through the distance of measuring basis board between rather than, has eliminated the direct contact of measuring device with the wheel of polishing, has avoided the greasy dirt to the measuring
