Problems solved by technology

[0004] In the prior art, the screwing process of the high-lock bolt threaded actuator needs manual assistance to put in the nut 200, and take out the broken collar 300 after the high-lock bolt is installed. The work efficiency is low, the degree of automation is low, and it is used The collar after being twisted off is easy to fall and remain in the aircraft, which brings great hidden danger to the safety performance of the aircraft

Abstract

The invention relates to the technical field of mechanical automation, and discloses a high-lock bolt screwing actuator and an assembly robot. The high-locking bolt screwing actuator comprises an actuator body, a nut tightening mechanism and an automatic feeding assembly. The nut tightening mechanism is arranged on the actuator body in a penetrating mode, the nut tightening mechanism can contain a nut and can drive the nut to rotate, the nut is connected to a bolt in a threaded mode, a lantern ring on the nut is twisted off, the automatic feeding assembly can convey the nut into the nut tightening mechanism, and the twisted-off lantern ring can be recycled. According to the high-lock bolt screwing actuator, when a high-locking bolt is screwed, automatic nut feeding and lantern ring recycling can be achieved. The assembly robot comprises the high-lock bolt screwing actuator, a robot body, a force sensing assembly and a visual assembly, and the assembly robot can be used for precisely screwing the high-lock bolt, automatically feeding and recycling the broken lantern ring.

Description

technical field [0001] The invention relates to the technical field of mechanical automation, in particular to a high-lock bolt threaded actuator and an assembly robot. Background technique [0002] With the continuous improvement of aircraft performance requirements, composite materials are used more and more in aircraft manufacturing. In order not to affect the performance of composite materials and ensure that the fasteners can reach the preset preload, composite materials usually use high-lock The bolts are tightened. [0003] Such as figure 1 As shown, the high-lock bolt includes a bolt 100 and a nut 200. A collar 300 is provided at the end of the nut 200. During installation, the installation tool twists the collar 300 to screw the nut 200 on the bolt 100. When the fastener reaches a predetermined When the load or pretightening force is reached, the collar 300 reaches its shear limit and is sheared off by the installation tool, and the installation of the high lock b...
