A rotatable machine table

Abstract

This utility model relates to the field of machine tool worktables and discloses a rotatable machine tool worktable, including a machine tool base. A connecting bracket is fixedly connected to the right side of the machine tool base, and a worktable is fixedly connected to the right side of the connecting bracket. A rotating mechanism is provided inside the connecting bracket, and a turntable is rotatably connected to the top of the worktable. A positioning mechanism is provided on the top of the turntable. The positioning mechanism includes a limiting shell, which is fixedly connected to the top of the turntable. A circular plate is provided in the center of the interior of the limiting shell, and an extrusion strip is fixedly connected to the circumferential surface of the circular plate. In this utility model, when the circular plate is rotated by a servo motor, the pressure plate drives the clamping block to move away from the circular plate, so that the clamping block abuts tightly against the inner wall of the cylindrical tube workpiece, thereby achieving stable clamping of the workpiece, providing stable multi-directional clamping force, improving the stability of fixing cylindrical tube workpieces, and improving applicability.
