Description

Technical Field

[0001] The utility model relates to the technical field of bolt tightening, in particular to a tightening manipulator for a bolt tightening station. Background Art

[0002] Definition of bolt tightening: The purpose of bolt connection is to make the two connected bodies fit tightly and bear a certain load. It is also necessary to have sufficient clamping force between the two connected bodies to ensure the reliable connection and normal operation of the connected parts. This requires that the bolts used for connection must have sufficient axial preload after tightening. However, the application of these forces is also achieved by "tightening". The tightening manipulator is an electric tightening tool. The application of servo tightening machines in the production and assembly process can reduce the labor intensity of employees. During the tightening process, the tightening torque and the force cannot be accurately controlled, resulting in too small clamping force. The bolts may loosen due to vibration or cyclic load. Excessive clamping force can easily lead to fracture and deformation of the connecting components. The application of servo tightening machines in the production and assembly process reduces the labor intensity of employees and avoids quality accidents caused by employee fatigue, improves product quality, and reduces production costs.

[0003] As shown in the application number: CN202120067000.9, the present application relates to an automatic tightening manipulator, comprising a connecting plate fixedly connected to a machine body, the connecting plate being rotatably connected to a driving cylinder along the length direction, the end of the connecting plate away from the machine body being rotatably connected to a connecting rod consistent with the rotation direction of the driving cylinder, the driving cylinder connecting rod being rotatably connected to the connecting rod and driving the connecting rod to rotate, a driving motor being fixed to the connecting rod, and a screwdriver for tightening screws being connected to the output shaft of the driving motor. When there is an obstacle above the screw, the driving cylinder starts the connecting rod to rotate so that the driving motor is located directly above the screw. The present application is convenient for tightening screws with obstacles above.
