The invention relates to the technical field of lead screw mechanisms, in particular to a double-lead-screw lifting mechanism which comprises a mounting plate, a fixing plate is arranged at the top of the mounting plate, supporting columns are arranged between the mounting plate and the fixing plate and used for fixing the mounting plate and the fixing plate, a driving unit is arranged at the top of the mounting plate, and two transmission mechanisms are arranged on one side of the driving unit. An output shaft of the driving unit is connected with the input end of one transmission mechanism, the input end of the transmission mechanism is further coupled with the input end of the other transmission mechanism, so that it is guaranteed that the two transmission mechanisms are in the same direction and at the same speed, and the output ends of the two transmission mechanisms are each provided with a lead screw body. By arranging the two sets of lead screw bodies and the stroke limiting mechanism, the problem that stress of the lifting plate is not uniform is solved, synchronism of the lifting plate is guaranteed, the stroke limiting mechanism can limit the stroke of the lifting mechanism, and when the lifting mechanism has wrong over-stroke, equipment can be automatically stopped through the stroke limiting mechanism, and damage to the equipment is avoided.
本发明涉及丝杆机构技术领域,具体的说是一种双丝杆升降机构,包括安装板,所述安装板顶部设置有固定板,所述安装板与固定板之间设置有支撑柱,用于将两板固定,所述安装板顶部设置有驱动单元,所述驱动单元一侧设置有两传动机构,所述驱动单元的输出轴与其中一组传动机构的输入端连接,该组传动机构的输入端还和另一组传动机构的输入端耦合,以保证两组传动机构同向同速,两组所述传动机构的输出端均设置有丝杆主体,通过设置两组丝杆主体以及行程限位机构,解决了升降板的受力不均匀,保证了升降板的同步性,而行程限位机构可以限制升降机构的行程,当升降机构发生错误的过行程问题,通过行程限位机构可以使得设备自停,避免设备的损坏。
