Problems solved by technology

[0002] In industrial production, a joint often requires multiple bolts to be tightened. If the bolts cannot be tightened at the same time, the pre-tightening force of the bolts will be reduced. A multi-axis thread synchronous tightening device is needed to realize the simultaneous tightening of bolts.
[0003] The existing multi-axis synchronous tightening method generally tightens each bolt in turn, so that the above-mentioned multi-axis synchronous tightening method is not high enough in tightening synchronization, and it is also not conducive to the synchronous tightening operation of multiple bolts on the connector.

Embodiment Construction

[0050] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] Such as figure 1 and figure 2 As shown, a multi-axis thread synchronous tightening control method of the present invention is used for tightening a multi-axis system composed of multiple bolts to be tightened. In the multi-axis system, each bolt to be tightened corresponds to a tightening axis. The multi-axis thread synchronous tightening control method includes the following steps:

[0052] Step S110, tighten each bolt to be fastened, so that all the bolts to be fastened complete the stage of searching for caps, and realize the initial docking operation between the end tool and the bolt head of the bolt to be fastened; wherein, the completion of the stage of searching for caps refers to the e...

Abstract

The invention discloses a multi-shaft thread synchronous tightening control method. The multi-shaft thread synchronous tightening control method comprises the steps that all to-be-fastened bolts are tightened; a tail end tool accelerates to rotate to an idle rotating speed; the thread part of each to-be-fastened bolt is detected; the fitting points of all the to-be-fastened bolts are detected; the to-be-fastened bolts completing the fitting point detection stage enter the fitting stage; the to-be-fastened bolts completing the fitting stage enter the reverse screwing stage; the to-be-fastened bolts completing the reverse screwing stage enter the screwing stage; and all the to-be-fastened bolts are stopped from being tightened. In the tightening process of the to-be-tightened bolts, all tightening shafts must be in the same working stage at the same moment, only when all tightening shafts meet the judgment conditions of the working stage, the next working stage operation can be carried out, and when any tightening shaft goes wrong in the tightening process, all the tightening shafts stop tightening.

Description

technical field [0001] The invention relates to the technical field of bolt tightening, in particular to a multi-axis thread synchronous tightening control method. Background technique [0002] In industrial production, a connecting piece often requires multiple bolts to be tightened. If the bolts cannot be tightened at the same time, the pre-tightening force of the bolts will be reduced. A multi-axis thread synchronous tightening device is needed to realize the simultaneous tightening of the bolts. [0003] The existing multi-axis synchronous tightening method generally tightens each bolt in sequence, so that the multi-axis synchronous tightening method is not high enough in tightening synchronization, and is not conducive to the synchronous tightening operation of multiple bolts on the connector. Contents of the invention [0004] Based on this, it is necessary to provide a multi-axis thread synchronous tightening control method for the deficiencies of the existing techn...
