Bolt assembly fastening device

Abstract

The invention discloses a bolt assembly fastening device comprising a device body, an automatic fastening wrench and a mechanical arm which is used for connecting the device body and the automatic fastening wrench and can be used for adjusting the position of the automatic fastening wrench. According to the automatic fastening wrench provided by the invention, through connection of the mechanicalarm with the device body, the three degrees of freedom movement of the automatic fastening wrench can be achieved through the mechanical arm so that the position of the automatic fastening wrench canbe adjusted at will; and the automatic fastening wrench is aligned to a bolt, and then the bolt is fastened by the automatic fastening wrench so that the assembly fastening of the bolt is achieved. The device can be flexibly moved (using a four-wheel trolley or AGV trolley as a carrier), and the automatic fastening wrench is carried by the mechanical arm which can be moved in a telescopic manner;the mechanical arm is resistant to torsion and counterforce, and the safety of assembly operation is ensured; and an operator only needs to adjust the positions of the mechanical arm and the automaticfastening wrench, and the labor intensity for assembly is reduced.

Description

technical field [0001] The invention relates to the technical field of equipment manufacturing, in particular to a bolt assembly fastening device. Background technique [0002] During the assembly process of electromechanical products such as motors and transformers, it is necessary to use multiple sets of bolts and nuts for fixing, and the bolts have many specifications and large torques. In the prior art, workers need to use manual torque wrench or hand-held automatic tightening wrench to fix the bolts. Manual torque wrench requires workers to tighten manually, which is labor-intensive and has poor tightening torque accuracy; although the hand-held automatic tightening wrench can reduce the The labor intensity of small workers, but the reaction force in the fastening process of high-torque bolts is large, which is easy to cause injury to workers, and the safety is poor. [0003] Therefore, how to reduce the labor intensity of fastening bolts, increase its safety, and impr...
