Screw fastening device

The invention provides a screw fastening device. The screw fastening device comprises a bracket and a fastening mechanism supported on the bracket through a Z-axis feeding mechanism. The fastening mechanism comprises a fastening mechanism bracket supported on the z-axis feeding mechanism, a fastening motor supported on the fastening mechanism bracket and a screw adsorption joint which is in transmission connection with the fastening motor and used for receiving screws. The Z-axis feeding mechanism can drive the fastening mechanism to move back and forth in the axial direction of an output shaft of the fastening motor. By means of the screw fastening device, screws can be automatically assembled, the production efficiency is improved, and the accuracy of assembly is improved. 本发明提供了种螺钉拧紧装置，包括支架、通过Z轴进给机构支撑在支架上的拧紧机构，所述拧紧机构包括支撑在Z轴进给机构上的拧紧机构支架、支撑在拧紧机构支架上的拧紧电机以及与拧紧电机传动连接的用以接收螺钉的螺钉吸附接头，所述Z轴进给机构能够带动拧紧机构沿着拧紧电机输出轴的轴线方向来回移动。该螺钉拧紧装置能够实现螺钉的自动装配，不仅提高了生产效率，也提高了装配的精度。
