A kind of rotation and revolution mechanism and milling head and machine tool using the mechanism

Abstract

The invention relates to an autorotation and revolution mechanism, and a cutter head and a machine tool using the mechanism. The autorotation and revolution mechanism comprises a base, wherein an input shaft, an output shaft and a rotating member are arranged on the base; the output shaft is parallel and eccentric to the input shaft; the rotating member is provided with an eccentric hole; the output shaft is rotationally inserted into the eccentric hole of the rotating member; a transmission mechanism is arranged between the input shaft and the output shaft; an eccentric distance of the eccentric hole of the rotating member is equal to the eccentric distances of the input shaft and the output shaft; the rotating member is rotationally supported on the base, and is connected with a revolution driving mechanism used for driving the rotating member to autorotate; a rotating axis of the rotating member is coincided with an axis of the input shaft; and the output shaft rotate around the rotating axis of the rotating member. The machine tool comprises the autorotation and revolution mechanism. Revolution of the mechanism can be realized inly only by driving the rotating member and the output shaft to rotate, without driving the whole mechanism to rotate, so that the energy consumption is reduced.

Description

technical field [0001] The invention relates to a self-rotation and revolution mechanism, a milling head and a machine tool using the mechanism. Background technique [0002] In the field of mechanical processing, some large workpieces have a large processing area, which requires the cooperation of the workpiece and the machine tool to complete, and the revolution of the machining tool relative to the center of the workpiece and the rotation of the tool can be completed, such as the surface of the bolster core, such as figure 1 As shown, the processing content of the bolster core plate surface includes the bottom surface of the core plate 2. Since the bottom surface of the center plate is a large-area torus, and the bolster is heavy, it cannot realize self-rotation, so the main shaft of the machine tool is required to be able to rotate and revolve at the same time. Ordinary machine tool spindles can only achieve self-rotation and axial feed, so they need to be processed by a...
