Abstract

The invention discloses a bolt fastening device which comprises a tightening gun, a coupling and a sleeve which are connected in sequence, wherein a first elastic telescoping mechanism is arranged inthe coupling, a second elastic telescoping mechanism capable of enabling the sleeve to move along the axial direction of the coupling is arranged at the joint of the coupling and the sleeve, and the elastic coefficient of the first elastic telescoping mechanism is greater than the elastic coefficient of the second elastic telescoping mechanism. The bolt tightening device can effectively meet low elastic coefficient when the bolt is combined with the sleeve and high elastic coefficient when the bolt is screwed into a threaded hole, so as to improve the equipment adaptability and stability.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a bolt tightening device. Background technique [0002] At present, the bolt tightening station on the manufacturing production line generally adopts the method of tightening gun + coupling + sleeve. The tightening gun and the coupling fixing seat are fastened together by bolts. The telescopic shaft of the coupling is relatively The fixed seat of the coupling has an axial degree of freedom and a rotational degree of freedom. The inner spring of the coupling keeps the coupling extended. When the telescopic shaft of the coupling is subjected to axial pressure, it will shrink in the corresponding distance. When tightened When the gun rotates, it drives the telescopic shaft of the coupling to rotate, and the sleeve also rotates with the telescopic shaft of the coupling. The bolts on the sleeve are screwed into the threaded holes, and the telescopic function of the coupli...
