Abstract

The embodiment of the invention provides a normal measuring device. The normal measuring device includes a leveling disc, an angular displacement table, a standard gauge block and a laser ranging sensor assembly, wherein the angular displacement table is located on a workbench of a to-be-calibrated system; the leveling disc is installed on a main shaft of a machining tool and is moved down to theupper plane of the angular displacement table, the leveling disc is leveled by adjusting the angle of the angle displacement table; the standard gauge block is arranged between the angular displacement table and the leveling disc; the laser ranging sensor assembly comprises four laser ranging sensors which emit lasers to the angular displacement table and the standard gauge block on the angular displacement table correspondingly to obtain the numerical difference of the laser ranging sensors and the height of the standard gauge block; according to the numerical difference of the laser rangingsensors and the height of the standard gauge block, the angle between the lasers emitted from the laser ranging sensors and the upper plane of the angular displacement table is calculated to be used for calibration of the to-be-calibrated system.

Description

technical field [0001] The invention relates to a calibration method of a normal direction measuring device, in particular to a calibration method of a normal direction measuring device based on a laser distance measuring sensor. Background technique [0002] At present, in the field of manufacturing large-scale equipment such as launch vehicles and aircraft, the application of flexible manufacturing technology has become the mainstream development trend of digital manufacturing at home and abroad. When robots and special end effectors are used for flexible automatic hole making of structural curved surfaces, the normal measuring device is often used to measure the normal direction of the hole making to ensure that the angle between the hole making axis and the normal direction of the curved surface meets the accuracy requirements. In general, the normal direction measuring device is composed of 4 sets of laser distance measuring sensors and the presser foot at the front end...
