A variable cross-section outer cylinder surface sander suitable for timber mainly comprises an abrasive belt, a feeding plate, a receiving hopper, a press wheel mechanism, a rod end joint bearing, a screw and a spring. When the variable cross-section outer cylinder surface sander is in work, a workpiece placed on the feeding plate is pressed on the abrasive belt through a press wheel, the press wheel and the abrasive belt rotate clockwise to drive the workpiece to rotate in a counter-clockwise direction and be polished through the abrasive belt along the circumference, and simultaneously the workpiece is gradually contacted with the press wheel along the axial direction of the workpiece, moves along the feeding plate and is finally ejected out to the receiving hopper. When the workpiece section varies, on one hand, the press wheel, a press wheel horizontal support, the rod end joint bearing and the screw move horizontally relative to a machine frame, and on the other hand, the rod end joint bearing enables the press wheel and the press wheel horizontal support to perform tiny deflection relative to the screw, simultaneously a press wheel inclined support performs tiny deflection around a press wheel inclined support transmission shaft, so that the relative positions of the press wheel and the workpiece can automatically change, and polishing of the variable cross-section outer cylinder surface is achieved. The variable cross-section outer cylinder surface sander is good in polishing effect, strong in adaptability, simple in structure and simple and convenient to operate.
