Abstract
A measuring device is disclosed which contains a sensor fastened to sensor holding elements (4, 5, 6, 7, 8) and suspended so as to be displaceable in relation to a frame (1) in three orthogonal directions (x, y, z). For each direction of displacement, two parallel moving bridges (11 and 12, 20 and 21, 28 and 24) are provided which are hinged on rigid connecting elements (13, 14, 22, 25). The device permits the return of the sensor to its reference position in the first two directions of displacement (x, y) by gravity or by centering elements provided for that purpose.
Claims28
A three-dimensional measuring device containing at least one measuring sensor suspended by means of a suspension device, so as to be simultaneously displaceable in three orthogonal directions identified as x, y and z at right angles to a frame, that suspension device comprising, for each direction of displacement two moving bridges parallel to each other and joined by two rigid connecting elements hinged on the bridges so as to form a deformable frame, and a measuring detector to measure the relative displacement of the two bridges, characterized in that the suspension device comprises for the x direction a first upper bridge integral with the frame and a first lower bridge, for the y direction a second upper bridge rigidly connected to the first lower bridge and a second lower bridge, those second bridges located in the space separating the first upper and lower bridges, and for the z direction a first side bridge rigidly connected to the second lower bridge and a second side bridge to which said measuring sensor is fastened, said measuring sensor being moved to a reference position in the first two directions by gravity.
