This utility model relates to the field of insulating pull rod press-fitting technology, specifically to a quick-assembly insulating pull rod press-fitting device, including a base, an electric slide rail mounted on the top of the base, an electric slider mounted on the inner wall of the electric slide rail, and a fixing device mounted on the top of the electric slider; the fixing device includes a connecting block, which is fixedly connected to the bottom of the electric slider, a groove is formed on the side of the connecting block, a moving block is slidably connected to the inner wall of the groove, a connecting rod is fixedly connected to the side of the moving block, and a fixing rod is fixedly connected to the side of the connecting rod. This utility model uses an electric telescopic rod to drive a connecting plate to move to the left, which in turn causes four centering blocks to evenly contact and center the insulating pull rod passing through the first and second through holes from all sides. This replaces the method of manually twisting the pull rod for coarse positioning, achieving automatic, precise, and reliable centering, providing a precise foundation for subsequent operations (such as clamping and moving).
