The invention aims at disclosing a graphite crucible clamp which comprises a frame, a driving device and a clamping arm, the driving device is installed in the frame and connected with a driving head through a force applying rod, the driving head is connected with the middle of the clamping arm through a pin shaft, and the clamping arm is connected with the driving head through a force applying rod. The upper ends of the clamping arms are in pin shaft connection with connecting rods and are in pin shaft connection with the bottom of the frame through the connecting rods, and the lower ends of the clamping arms are connected with grabbing nails; compared with the prior art, the vertical force of the telescopic motion of the driving device is converted into the horizontal force of the scratch nail through the connecting rod and the pin shaft, the scratch nail is unfolded to be in contact with and fixed to the crucible when the driving device shrinks, and the scratch nail shrinks to be separated from the crucible when the driving device stretches, so that the crucible is automatically fixed, and various risks caused by direct contact between manpower and the crucible are avoided; by adjusting the stroke of the driving device, the crucible transfer device can be suitable for transferring crucibles of various sizes, and the purpose of the invention is achieved.

    本发明的目的在于公开一种石墨坩埚夹具,它包括框架、驱动装置和夹紧臂,所述驱动装置安装在所述框架中,所述驱动装置通过一加力杆连接驱动头,所述驱动头与所述夹紧臂的中部互相销轴连接,所述夹紧臂的上端销轴连接有连杆并通过连杆与所述框架底部互相销轴连接,所述夹紧臂的下端连接有抓钉;与现有技术相比,将驱动装置伸缩运动的垂直力通过连杆及销轴转换为抓钉的水平力,驱动装置收缩时抓钉展开与坩埚接触并固定,驱动装置伸展时抓钉收缩与坩埚分离,实现自动化固定坩埚,解决人工与坩埚直接接触的各类风险,通过调整驱动装置行程可适用于各类尺寸坩埚的转运,实现本发明的目的。
