This utility model has the advantages that
This utility model piston rod outer end is connected with earrings tailing screw flight, and piston rod outer end is welded with earrings
Connect, welding region axial gap between piston rod outer end and earrings.This utility model uses
Threaded and the mode that combines of welding, threaded realizes determining of piston rod and earrings afterbody
Position, it is ensured that the concentricity of the two, it is easier to connect, be not required to special equipment, and piston rod and ear
Ring is threaded, it is possible to effectively strengthen the tensile strength of piston rod and earrings.This utility model welds
After need not reprocessing, simple in construction, low cost, process-cycle are short, and functional reliability is high.
When earrings afterbody is threadeded with piston rod outer end, this utility model provides three kinds of preferred sides
Case, the first is to have the first connecting hole at earrings afterbody, and the first connecting hole is provided with female thread, the
One connecting hole outer end is provided with the first positioning spigot；Piston rod outer end is correspondingly provided with and earrings connecting hole phase
The boss coordinated, boss is provided with external screw thread, and boss the inner is provided with matches with the first positioning spigot
Second positioning spigot；The second is that earrings afterbody is provided with external screw thread, and the inner of earrings afterbody is provided with
Three positioning spigots；Piston rod outer end has the second connecting hole matched with earrings afterbody, and second even
Connecing hole and be provided with female thread, it is fixed that the second connecting hole outer end is provided with the 4th matched with the 3rd positioning spigot
Position seam；The third is that earrings afterbody has the 3rd connecting hole, and the 3rd connecting hole is provided with female thread,
3rd connecting hole outer end is provided with the 5th positioning spigot；Piston rod outer end has the 4th connecting hole, and the 4th
Connecting hole is provided with female thread, and the 4th connecting hole outer end is provided with the 6th positioning spigot；Earrings afterbody and work
Stopper rod outer end by Threaded Connector Coupling connect, to be provided with in the middle part of Threaded Connector Coupling with the 5th positioning spigot, the 6th
The seam locating ring that positioning spigot matches.Above-mentioned three kinds of preferred versions are all by earrings afterbody and work
Positioning spigot on stopper rod coordinates, it is achieved earrings and effective location of piston rod, further facilitates ear
Ring and the connection of piston rod, it is ensured that functional reliability.
