Abstract

The invention discloses a simple calibration method of a laser centering instrument, which comprises simple calibration for a horizontal mechanical displacement centering indication value and a vertical mechanical displacement centering indication value of the laser centering instrument. The simple calibration for the horizontal mechanical displacement centering indication value comprises the steps of installation of the laser centering instrument, zero position adjustment, 3-o' clock direction detection and 9-o' clock direction detection. The simple calibration for the vertical mechanical displacement centering indication value comprises the steps of installation of the laser centering instrument, zero position adjustment and detection for the actual displacement amount of vertical mechanical displacement. According to the simple calibration method disclosed by the invention, a simple standard device is combined by using a high-precision measurement core shaft and a universal tool microscope so as to carry out centering calibration for the laser centering instrument in the horizontal and vertical directions, and being convenient in measurement and high in accuracy. In practical production, self calibration can be carried out immediately when an abnormal value occurs when the laser centering instrument is in use, and outgoing calibration is not required, thereby shortening the time of fault diagnosis, and improving usage efficiency of the laser centering instrument.

Description

technical field [0001] The invention relates to a calibration method, in particular to a simple calibration method for a laser alignment instrument. Background technique [0002] All shafts, whether straight or curved, rotate about an axis called the center of rotation. The shape of the center of rotation is a straight line. When the respective centers of rotation of two axes form the same straight line, it is called concentric (collinear). When two shafts are not concentric, it is called misalignment. Mechanical displacement alignment refers to the center alignment of the connection parts when the couplings of mechanical equipment are connected to ensure the coaxiality of the installation of the couplings of the two equipments, so that the two equipments can avoid damage caused by vibration and jamming due to the deflection of the installation connection Equipment. The main function of the laser alignment instrument in the maintenance process of mechanical equipment is:...
