Abstract
The utility model relates to a numerically-controlled machine tool multi-stage telescopic device, wherein locking devices are arranged on the upper and the lower sides of a side wall of a telescopic pipe, slider heads which are embed on the inner wall of the telescopic pipe are arranged on the locking devices, tapered planes which are closely contacted with the telescopic pipe are arranged on the top portions of the slider heads, fixture blocks are arranged on the outer wall of the telescopic pipe along the radial direction in a sliding mode, setup springs are arranged in straight through holes, the two ends of the setup springs are respectively supported on the bottom portion of the fixture blocks and the tapered planes of the slider heads, limit rings are fixedly welded on the outer walls of the fixture blocks, and clamp slots are arranged on the outer wall of the front end of a center support rod corresponding to the positions of the slider heads. The locking devices are arranged between the center support rod and the telescopic pipe by adopting a sleeved mode, and are steadily and reliably locked mechanically, and slider heads can be clamped into the clamp slots because of elastic force of a spring when the telescopic pipe forwardly moves a certain distance, thereby forming locking, and preventing excessive expansion. Simultaneously, the numerically-controlled machine tool multi-stage telescopic device is excellent in structure stability, and is suitable for multi-stage sleeved expansion.
