Tile key thickness measurement and calibration device for tile gap adjustment

The utility model provides a tile key thickness measurement and calibration device for tile gap adjustment. The device comprises a base with a vertical rod and is characterized in that a sliding rail is arranged on the base, one end of the sliding rail is provided with a movable supporting block connected with a moving mechanism, the other end of the sliding rail is provided with a fixed supporting block provided with a measuring through hole and a magnetic plate on the back face, and a locking block connected with the sliding rail. After the device is calibrated, the thickness of an old tile key can be accurately measured, the machining thickness of a new tile key and the grinding amount of the old tile key are accurately obtained, the bearing bush gap adjusting precision is improved, the time of the bearing bush gap adjusting process is saved, the working efficiency is improved, and many problems caused by measurement errors are avoided. And normal operation of the guide bearing of the water-turbine generat
