This utility model discloses a leveling device for the post-installation of large-diameter rotating slides, comprising an adjusting base, a pressure plate, and anchor bolts. The adjusting base has locking threaded holes on both sides of its top. Connecting studs are welded to both sides and the center of the bottom of the adjusting base, with the studs connected to support feet via threads. Square welding clearance grooves are provided on both sides of the adjusting base, and a rectangular pressure plate is positioned on top of the welding clearance grooves. Locking bolts are threaded to the locking threaded holes on both sides of the top of the pressure plate. Three straight-groove-shaped spot-welded clearance grooves are evenly distributed on the top of the pressure plate. A fan-shaped slide plate is positioned between the adjusting base and the pressure plate, with the adjusting base positioned at the joint of the two slide plates. This utility model facilitates the fixing and leveling of the joint of the slide plates, which is beneficial for the installation of the entire slide, effectively improving the efficiency and accuracy of leveling, and is easy to use.
