Abstract

An energy-saving clamping device for lathes includes a main spindle, wherein the main spindle is arranged at the front and the rear ends of a main spindle box through a front gland and a rear gland; a pull rod is sleeved in the main spindle; both the front and the rear parts of the pull rod are extended out of the main spindle; a spring chuck is arranged at the front part of the pull rod; and a releasing and clamping mechanism is arranged at the rear part of the pull rod, and includes an elastic component which is arranged at the rear part of the pull rod and can control the release and clamping of the spring chuck, as well as a hollow internal rotation hydraulic cylinder which can control the compression or reset of the elastic component. Through the discharge of hydraulic oil, the pull rod is pulled back under the restoring force of a disc spring, so that the spring chuck can clamp a workpiece (in a self-lock manner) until the workpiece processing is finished, during which the hydraulic oil cylinder needn't further apply work; and after the oil is re-fed to the hydraulic oil cylinder body, an oil cylinder piston compresses the disc spring to eject the pull rod forwards, so that the spring chuck can immediately release the workpiece. During the workpiece releasing and clamping processes, instantaneous hydraulic pressure is needed only when the workpiece is released by the spring chuck, that is, the hydraulic cylinder only needs to work instantaneously, which achieves the purposes of power and energy conservation.
