Abrégé

The present invention relates to a device and method for adjusting a relative angle of rotation (RV) between a first and a second threaded rod section (1' 1") at a first joint (28') by means of a measuring device (2), which measuring device (2) has an internal thread (33) corresponding to a first and second external thread (35', 35") of the first and second threaded rod sections (1',1"), whererin the measuring device (2) is moved during use in axial direction over the first joint (28') in a rotary motion. The method comprising the steps of; mount the measuring device (2) on the first threaded rod section (1'); mount the second threaded rod section (1 ") to the first threaded rod section (1'); move the measuring device (2) towards the first joint (28') until the internal thread (33) of the measuring device (2) abuts the second external thread (35") of the second threaded rod section (1 "); rotate the second threaded rod section (1") to a position wherein a first thread entrance (30') of said first external thread (35') of the first threaded rod section (1') matches a second thread entrance (30") of said second external thread (35") of the second threaded rod section (1"), in which position the measuring device (2) can be moved over the first joint (28'); lock the first joint (28'); move the measuring device (2) toward a second joint (28") between the second threaded rod section (1") and a third threaded rod section (1"').

The invention concerns a method for the manufacture of a section of screw rod (1', 1") that extends along the z-axis (Z). The method comprises the steps: processing of a workpiece (23) to comprise at least one threaded groove (11); processing of the workpiece (23) to comprise a first plane of contact (API) that extends transverse to the z-axis (Z); measuring in of the first plane of contact (API) and a first reference point (RP1) at the threaded groove (11) relative to each other; determination of the position of a first entry point (IP1) at the threaded groove (11) based on the said measuring in; processing of the workpiece (23) to comprise a first section of assembly thread (17) that demonstrates at least a first thread comprising a first connection point (FP1) that is connected at the first plane of contact (API). The invention concerns also a processing configuration for the manufacture of sections of screw rod (1, 1") and a multioperation machine (31) that is arranged for fully or partially automatic manufacture of sections of screw rod (1, 1"). The invention concerns also a computer program (P) at a processing configuration for the manufacture of sections of screw rod (1', 1").

Abrégé

The present invention concerns a torsional measuring device arranged for the setting of the search for a mutual centre line between a first and a second section of threaded rod (Γ, 1"), which torsional measuring device (41) is in interaction during use with the said first and second sections of threaded rod (Γ, 1"), whereby each one of first and second torsional devices (43', 43") arranged at the torsional measuring device (41) comprises a first and a second grip (45', 45") for attachment in a manner that allows it to be removed at the said first and second sections of threaded rod (Γ, 1"). A first lever part (47') at the first torsional device (43') can be coupled with the second torsional device (43") by means of a first adjustment element (49'). The present invention concerns also a method for the setting of the search for a mutual centre line with the aid of a torsional measuring device (41).
