Vacuum furnace rotating mechanism

Abstract

The application relates to the technical field of vacuum furnaces, and discloses a vacuum furnace rotating mechanism which comprises a bottom plate, a top plate, a furnace cover sealing head, a hollow shaft, a spline sleeve, a spline shaft, a support, a supporting leg, a first driving element and a second driving element. In use, under the driving of the second driving element, the spline shaft can slide, thereby driving the tray on the spline shaft to make lifting movement, so that the tray can be adjusted to a suitable position to process the material in the tray. During the processing, under the driving of the first driving element, the hollow shaft can rotate. Through the spline sleeve, the spline shaft can be driven to rotate. Then the tray is driven to rotate, and finally the material in the tray is driven to rotate, so that the material is uniformly heated, and the processing effect is improved. Moreover, since the positions of the top plate and the hollow shaft are unchanged, the position of the first driving element will not be raised or lowered. Therefore, the external cable of the first driving element will not be moved, wear and damage are avoided, and the risk of falling off is reduced.
