Description

technical field

[0001] The invention relates to a bolt tightening device, in particular to a torque controlled multi-axis bolt tightening machine. Background technique

[0002] Generally, the assembly line has many equipments and complex technologies, and there are many types of tightening machine tools used, which can be roughly divided into three types: electric single-axis tightening machine, electric multi-axis tightening machine and pneumatic single-axis tightening machine. Most of the electric multi-axis tightening machine transmits power through the pulley; the electric single-axis tightening machine is composed of a rotor and a stator, and the workpiece is tightened through the rotation of the rotor; the pneumatic single-axis tightening machine rotates the impeller through the airflow. The protection of the tightening machine is achieved by reducing the pressure through the pressure relief valve. When the assembled workpieces are in the same working plane or close t...
