Abstract
This utility model relates to the field of measurement technology, and in particular to a laser automatic measuring instrument, including a coordinate measuring machine (CMM) and an infrared ranging module mounted on the measuring head of the CMM. The infrared ranging module includes a calibration block, a mounting base, and a grating strip. The mounting base is fixedly installed on the top of the rotating part of the measuring head. Four mounting bases are provided and are evenly distributed axially. The grating strip is detachably inserted into the mounting base. The mounting base contains a storage battery and a data transmission center, which is a wireless signal transmitter. A charging interface is provided on one side of the mounting base, and the charging interface is electrically connected to the storage battery via a wire. The calibration block is fixedly installed on the top of the CMM's worktable. A ranging grating strip is required. At the beginning, the measuring head moves to the calibration position, and the grating strip is calibrated by the calibration block to obtain accurate data.
