Abstract / Hauptanspruch
Optoelectronic measuring device comprising at least two carrier bodies (3) joined to each other, a scale (2) arranged inside the carrier bodies (3), and a read head (1) that faces the scale (2) and that is movable longitudinally in relation to the carrier bodies (3), each carrier body (3) comprising a longitudinal inner surface (30a) on which the read head (1) runs when it moves, each carrier body (3) comprising an outer surface (30b) substantially parallel to the inner surface (30a), there being defined between the inner and outer surfaces (30a, 30b) a thickness (30c) of said carrier body (3),characterised in thatthe device (100) also comprises at least one additional element (47, 48) joined to each carrier body (3) that is used as a reference to align the carrier bodies (3) with each other, each additional element (47, 48) comprising a reference (400) arranged at a determined reference distance (D2) in relation to the inner surface (30a) of the corresponding carrier body (3),and the reference distances (D2) being equal for all the carrier bodies (3) and their corresponding references (400), the references (400) being aligned with each other, so that the inner surfaces (30a) of the various carrier bodies (3) are aligned, the device (100) comprising a first additional element (48) fixed to a lateral face (38) of a first carrier body (3) and a second additional element (47) fixed to a lateral face (38) of a carrier body (3) that is joined to the first carrier body (3), said additional elements (47, 48) cooperating with each other to join both carrier bodies (3), the second additional element (47) comprising a housing (47d) with a longitudinal central axis (47c) and the first additional element (48) comprising a projection (48d) with a longitudinal axis (48c) that is housed in the housing (47d) of said second additional element (47), the axis (47d, 48d) being aligned, said axis (47d,48d) corresponding with the reference (400) arranged at a reference distance (D2) in relation to the inner surface (30a) of the corresponding carrier body (3).

Method for aligning the carriers of the optoelectronic measuring device.
