The invention belongs to the technical field of automatic machining, and particularly relates to a linear lifting module which comprises a vertically-arranged lead screw, a lead screw seat movably arranged on the lead screw and a lead screw motor driving the lead screw to rotate in a fixed-axis mode. The module further comprises a hollow air shaft parallel to the lead screw, and a normally-closed valve assembly opened under pressure is arranged on the hollow air shaft and corresponds to an inner cavity of the hollow air shaft. A through hole matched with the hollow air shaft is formed in the lead screw seat, and sealing rubber sleeves matched with the hollow air shaft are arranged at the upper end and the lower end of the through hole. An air chamber is concavely formed in the inner wall of the through hole, and an air nozzle communicated with the air chamber is arranged on the screw rod seat; a trigger piece for extruding the normally closed valve assembly to be opened when the screw rod seat moves in place is also arranged in the air chamber; in the working process, through cooperation of the hollow air shaft and the normally-closed valve assembly, the number of connecting air pipes moving along with the lead screw base can be reduced, and the operation safety of equipment is greatly improved.
本发明属于自动化加工技术领域,尤其是一种直线升降模组,该模组包括竖直设置的丝杆,和活动设置在丝杆上的丝杆座,以及驱动丝杆定轴旋转的丝杆电机;该模组还包括与丝杆平行设置的空心气轴,空心气轴上对应其内腔设有受压打开的常闭阀组件;丝杆座上设有与空心气轴适配的通孔,通孔的上下两端均设有与空心气轴适配的密封胶套;通孔的内壁上凹陷成型有气室,丝杆座上设有与气室连通的气嘴;气室内还设有当丝杆座运动到位时挤压常闭阀组件打开的触发件;工作时,通过空心气轴和常闭阀组件的配合,可减少随丝杆座一并运动的连接气管的设置,大大增加了设备的运行安全性。
