An auxiliary-manpower-free support device for pipe machining relates to the technical field of building machinery and comprises a base, a sleeve, a screw, a fixing block, a U-shaped seat and a position adjusting mechanism, the sleeve is fixedly arranged at the top end of the base in the longitudinal direction, the screw is connected into the sleeve in a threaded mode, the upper end of the screw extends upwards along the top of the sleeve, and the position adjusting mechanism is arranged on the base. A fixing block is arranged at the top end of the screw rod, a U-shaped seat is arranged at the top end of the fixing block, and the fixing block is connected with a position adjusting mechanism. When a machine tool is used for machining a pipe, the positioning and moving functions of the pipe can be achieved instead of manual work, then labor is saved, and the economic cost of an enterprise is reduced.
