The invention relates to the technical field of crucible hot working, in particular to a linear crucible lifting device which comprises a main vertical frame, a lifting and clamping assembly and a clamping rod assembly, a lifting machine base is arranged on the surface of the main vertical frame, a fixing base used for supporting the lifting and clamping assembly is fixedly installed on one side of the lifting machine base, and a driving motor is fixedly installed on the surface of the fixing base; the lifting and clamping assembly comprises a driving box, a main fluted disc, a plurality of movable lug plates and a linkage rod, the main fluted disc, the movable lug plates and the linkage rod are located on the inner side of the driving box, a positioning ring is fixedly installed on the inner side of the driving box, and the driving box is connected with the positioning ring through a plurality of rotating pins. According to the crucible lifting device, the multiple clamping rod assemblies are controlled to move in the radial direction through the main fluted discs and the linkage rods on the surfaces of the lifting and clamping assemblies, and one of external expansion type inner supporting positioning or external clamping positioning can be selected according to crucibles of different specifications, so that the crucible is subjected to nondestructive tooling, falling is prevented, and the stability in the lifting process is improved.

    本发明涉及坩埚热加工技术领域,具体为一种直线式坩埚提升装置,包括:主立架、提夹组件和夹杆组件,所述主立架的表面设有提升机座,所述提升机座的一侧固定安装有用于支撑提夹组件的固定座,所述固定座的表面固定安装有驱动电机,所述提夹组件包括驱动盒以及位于驱动盒内侧的主齿盘和若干动耳板、联动杆,所述驱动盒的内侧固定安装有定位环,且驱动盒和定位环之间通过若干转销连接。本发明中,通过提夹组件表面主齿盘、联动杆控制多个夹杆组件进行径向运动,可根据不同规格坩埚,选用外胀式内撑定位或外夹持定位中的一种,以对坩埚进行无损工装,防止脱落提高提升过程中的稳定性。
