Lifting device for ship manufacturing and processing

The utility model provides a lifting device for shipbuilding and machining, which belongs to the technical field of ships and comprises a screw rod and two screw rod nuts, the screw rod is rotatably connected to the inner walls of two sides of a sliding groove, and the two screw rod nuts are both in threaded connection to the circumferential surface of the screw rod. When a workpiece needs to be stabilized and fixed, the workpiece can be placed in a placement shell, then a motor is started to enable an output shaft of the motor to rotate, then a lead screw is driven to rotate, a lead screw nut in threaded connection with the circumferential surface of the lead screw is driven to move, two clamping plates are driven to move towards the close ends, and the workpiece is clamped; and therefore, the workpiece is prevented from being damaged due to separation caused by external buffering. 本实用新型提供一种船舶制造加工使用的升降装置，属于船舶技术领域，该船舶制造加工使用的升降装置包括丝杆，丝杆转动连接于滑动槽的两侧内壁，两个丝杆螺母，两个丝杆螺母均螺纹连接于丝杆的圆周表面，在需要将工件进行稳定和固定时，可以将其放置于放置壳内，而后启动电机使
