Axial fixing mechanism for automatic assembly of U-shaped pipe metal ring

The utility model provides an axial fixing mechanism for automatically assembling a U-shaped pipe metal ring, the axial fixing mechanism is fixed on an automatic assembling device for the U-shaped pipe metal ring, the automatic assembling device for the U-shaped pipe metal ring comprises a rack mechanism, a radial fixing mechanism, an axial fixing mechanism and a movable jig mechanism, the axial fixing mechanism is fixed to the rack mechanism and comprises an axial pressing plate, a pressing plate base plate, an axial mechanism base plate, an air cylinder base plate, a guide rod, a linear bearing, an air cylinder and a locking device, and the axial pressing plate acts together with the radial fixing mechanism and the movable jig mechanism through the air cylinder, the guide rod and the linear bearing. The air cylinder pushes the pressing plate to move towards the movable jig mechanism, and the pressing plate and the jig mechanism jointly achieve axial fixing of the U-shaped pipe metal ring. 本实用新型提供了一种U形管金属环自动
