Description

Technical Field

[0002] When assembling a nut on a workpiece, a nut is placed on the mounting hole of the workpiece, a backing plate is placed on the nut, and then a cylinder is used to push up a pressure rod. Through the lever principle, the other end of the pressure rod presses on the backing plate, and the backing plate can prevent damage to the nut. Then, through the transmission of force, the nut is pressed into the mounting hole of the workpiece.

[0003] However, when assembling a nut on a workpiece, the backing plate needs to be placed stably on the nut. Since the end of the nut is not stable, the backing plate is unstable when placed, and it will fall due to skewness during placement, affecting the assembly efficiency of the nut. Moreover, when pressing and installing the nut, the workpiece placed vertically on the backing plate will be skewed due to the force during pressing and installation, resulting in low installation quality of the nut, and the nut is skewed into the mounting hole.
