Abstract

The invention belongs to the technical field of bolt automatic assembly, and specifically relates to a robot end effector and system for bolt side assembly, aiming at realizing fully automatic bolt side disassembly and eliminating the reaction torque generated during the bolt tightening process; wherein, the robot end The actuator is used to assemble the target bolt, including a screwing device for side screwing of the bolt, a clamping device for fixing with the target base to eliminate the screwing torque, a bearing plate for carrying the clamping device and a An adjustment device for adjusting the height of the screwing device; the screwing device includes a first drive assembly, a C-shaped screw shaft and a variable-width screwing assembly, which can be screwed from the side of the bolt at any angle; the clamping device includes a second Three driving components, a fixed clamping component, a first movable clamping component and a second movable clamping component; through the present invention, efficient side dismounting of bolts and elimination of tightening reaction torque can be realized, greatly broadening the application scenarios of automatic screwing bolts .

Description

technical field [0001] The invention belongs to the technical field of automatic bolt assembly, and in particular relates to a robot end effector and a system for bolt side assembly. Background technique [0002] Bolted connections are used in all walks of life and play an extremely important role in production and life. The automatic disassembly and assembly of bolts can greatly improve production efficiency. At present, the use of a mature electric wrench at the end of the robot to achieve automatic locking and payment of bolts has been widely used. [0003] Most of the existing electric wrenches enter from top to bottom along the axis of the bolt, and the axis of the drive shaft basically coincides with the axis of the bolt, and the bolt is directly driven to rotate through the drive shaft. However, for some bolts used in special occasions, it is often difficult to directly drive their rotation by entering from the axis. For example, the target bolt of the 500-meter Ape...
