Description

Technical Field

[0001] The utility model specifically relates to a rotary riveting machine. Background Art

[0002] The rotary riveting machine is a kind of equipment developed based on the principle of cold rolling. The motor drives the riveting head to rotate, and then provides the power for pressing down, drives the riveting head close to the workpiece, so that the rivet is deformed and the workpiece is riveted together. The rotary riveting machine in the prior art has many shortcomings. For example, the pressing motor in the prior art is connected to the screw rod through a reducer and a coupling, and the spindle motor is connected to the rotary riveting spindle through a coupling. This method is not easy to find and replace when the accessories are damaged. For example, the rotary riveting machine spindle assembly of the rotary riveting machine in the prior art moves up and down through the cooperation of the spindle and the shaft hole. This structure has a relatively large friction force when pressed down. The dust generated by the wear of the shaft hole for a long time is easily solidified by mixing with the internal lubricating oil, resulting in increased friction. If damaged, it cannot be repaired. In addition, the rotary riveting machine spindle assembly of the rotary riveting machine in the prior art is through the cooperation of the shaft and the shaft hole. This structure requires difficult processing and high cost. In addition, there are many forms of hydraulic drive of the rotary riveting machine in the prior art, and oil leakage and oil seepage pollute the working environment.
