Abstract

PARALLEL-KINEMATICAL MACHINE WITH AN ACTIVE MEASURING SYSTEM A PARALLEL-KINEMATICAL MACHINE (1) WHICH HAS AT LEAST THREE SETTING DEVICE 5 (4.1. 4.2, 4.3) WHICH CAN BE LENGTHENED AND SHORTENED INDIVIDUALLY IN THEIR LONGITUDINAL DIRECTION, WHEREIN EACH SETTING DEVICE (4.1, 4.2, 4.3) IS CONNECTED TO A POSITIONING HEAD ( I 1) VIA A FIRST JOINT: WHEREIN EACH SETTING DEVICE (4.1, 4.2, 4.3) IS CONNECTED TO A MACHINE BASE (2) VIA A UNIVERSAL JOINT (3. 1, 3.2 3.3), AND WHEREIN THE POSITIONING HEAD (1 1) IS MOVABLE WITHIN A WORKING AREA IN RESPONSE TO 10 MANOEUVRING OF THE SETTING DEVICES (4.1, 4.2, 4.3), WHEREIN AT LEAST TWO REINFORCING BEAMS (5.1. 5.2, 5.2.1, 5.2.2) ARE EACH CONNECTED TO THE POSITIONING HEAD (1 1) VIA A RESPECTIVE BEAM ROTATION BEARING (10.1, 10.2). WHEREIN EACH OF SAID BEAM ROTATION BEARINGS (10.1, 10.2) HAS ONLY ONE DEGREE OF FREEDORN, ARID WHEREIN EACH OF SAID BEAM ROTATION BEARINGS IS PROVIDED WITH TWO ANGLE INDICATORS (5. 1 A 5. 1 B. 15 5.2A, 5.2B) WHICH ARE EACH CONNECTED TO THE BEAM ROTATION BEARING (1 0. 1. 10.2) SO THAT THE MEASURING POINTS OF TWO ANGLE INDICATORS (5. 1 A, 5. 1 B) WILL EACH BE SITUATED ON A RESPECTIVE SIDE OF THE FIRST BEARN ROTATION BEARING (1 0. I ) AND SO THAT THE MEASURING POINTS OF TWO ANGLE INDICATORS (5.2A, 5.2B) WILL EACH BE SITUATED OIL A RESPECTIVE SIDE OF THE SECOND BEAM ROTATION BEARING (10.2) SO THAT THE ANGLE 20 INDICATORS WILL FIRSTLY REGISTER AN ANGLE U.1, CF2, CT3, U, BETWEEN THE POSITIONING HEAD (1 1 ) AND RESPECTIVE REINFORCING BEAMS (5.1, 5.2) AND SECONDLY REGISTER A FIRST ANGULAR DIFFERENCE 01, WHERE R)1=CC2- AL, BETWEEN THE MEASURING POINTS OF THE TWO ANGLE INDICATORS (5.1 A, 5. 1 B) OF THE FIRST BEAM ROTATION BEARING (1 0. 1) AND ALSO 'I SECOND ANGULAR DIFFERENCE 02- WHERE N=U-4- (TI BETWEEN THE MEASURING POINTS OF 25 TWO ANGLE INDICATORS (5.2A, 5.2B) OF THE SECOND BEAM ROTATION BEARING (1 0.2) SUCH AS TO FORM AN ACTIVE MEASURING SYSTEM (AMS). WHEREIN IN THE CASE OF A LOADED MACHINE EACH DEVIATION IN THE VALUE OF THE ANGLES CII, 02, CT3, CT, FROM A NOMINAL ANGLE VALUE IN THE CASE OF A NON-LOADED MACHINE IS ADAPTED TO BE CORRECTED BY MANOEUVRING THE SETTING DEVICES (4.1, 4.2, 4.3) TO A CHANGED WORKING POSITIONING OF 30 THE POSITIONING HEAD (1 1).
