Problems solved by technology

[0003] At present, although most enterprises stipulate the tightening sequence and position of bolts in the work instructions, due to the large number of bolts and the high labor intensity of workers, it is easy to cause job burnout, resulting in the tightening sequence and tightening position of bolts. The fixed position is often wrong, which reduces the pressure uniformity between the parts connected by bolts, reduces the rigidity of the bolted assembly, and reduces the service life of the bolted assembly

Abstract

The invention discloses a bolt fastening device and an assembly system. The bolt fastening device comprises a stand column; a first anti-torque arm rotatably connected to the stand column; a first angle encoder used for collecting first rotation angle information of the first anti-torque arm; a second anti-torque arm rotatably connected to the end, away from the stand column, of the first anti-torque arm; a second angle encoder used for collecting second rotation angle information of the second anti-torque arm; a torque wrench arranged on the second anti-torque arm; and a central guide controller which can receive and store the preset fastening sequence and the preset fastening position in advance. By means of the bolt fastening device of the invention, the actual fastening position can be consistent with the preset fastening position, the actual fastening sequence is consistent with the preset fastening sequence, the error rate of the bolt fastening sequence and the bolt fastening position is reduced, the pressure uniformity between parts is improved, the rigidity of a bolt connection assembly is enhanced, and the service life of the bolt connection assembly is prolonged.

Description

technical field [0001] The invention relates to the field of assembly technology, in particular to a bolt fastening device and an assembly system. Background technique [0002] In the machinery manufacturing industry, it is often necessary to fasten a large number of bolts. Among them, most of the bolts need to be tightened strictly in accordance with the specified sequence and specified position. [0003] At present, although most enterprises stipulate the tightening sequence and position of bolts in the work instructions, due to the large number of bolts and the high labor intensity of workers, it is easy to cause job burnout, resulting in the tightening sequence and tightening position of bolts. The fixing position is often wrong, which reduces the pressure uniformity between the parts connected by bolts, reduces the rigidity of the bolted assembly, and reduces the service life of the bolted assembly. [0004] Therefore, how to prolong the service life of the bolted ass...
