Abstract

The invention discloses an automatic bolt tightening device of a six-axis robot. The automatic bolt tightening device of the six-axis robot includes a shell rear end, a shell front end, an alternatingcurrent servo motor, a harmonic reducer, an adapter flange, a toque sensor, an output shaft and a sleeve. The automatic bolt tightening device of the six-axis robot has the advantages and benefits that fully automatic bolt tightening operation can be finished according to the automatic bolt tightening device of the six-axis robot, the automatic bolt tightening device of the six-axis robot can beapplied to a production line with automatic assembling, accuracy and the assembling quality of bolt connection are improved greatly, installing time is shortened, and labour intensity of an operator is reduced; and the sleeve of the automatic bolt tightening device of the six-axis robot can be changed quickly, bolts with the different models can be tightened, and assembling work is convenient.

Description

technical field [0001] The invention relates to an automatic bolt tightening device of a six-axis robot, which belongs to the technical field of bolt connection. Background technique [0002] Bolt connection is simple, reliable, and easy to assemble and disassemble. It is a common fixed connection method and is widely used in electromechanical products. The quality of the bolted connection directly affects the overall quality of the product. In order to improve the reliability and stability of bolt tightening operations, an automatic tightening device integrating a motor, a reduction transmission structure, a force sensor and a PLC controller has been widely used in the assembly and manufacture of electromechanical products. [0003] Although the above-mentioned tightening device can ensure the quality of bolt tightening by controlling the torque, as a semi-automatic product, its tightening efficiency is low and the tightening quality is unreliable. The six-axis industrial...
