Detailed description of the invention
Below in conjunction with accompanying drawing, the art of this patent scheme is described further:
As in figure 2 it is shown, this patent is mainly made up of mandrel 1, sealing ring 2, spacing collar 3, collar bush 4, spring 5, jump ring 6, pin 7.Spring 5 is arranged in the axial blind hole of collar bush 4.Sealing ring 2 is set between mandrel 1 and collar bush 4.The endoporus of spacing collar 3 coordinates with collar bush 4 cylindrical.It is provided with in the axial blind hole that the mandrel 1 of sealing ring 2 inserts collar bush 4.Pin 7 sequentially passes through the radial hole of the radial hole of spacing collar 3, the radial direction U groove of collar bush 4, mandrel 1, completes to assemble.Jump ring 6 is arranged in the jump-ring slot of pin 7 end, it is prevented that pin 7 comes off.Slightly larger than the U-type groove of the collar bush 4 of pin 4 dimension width, making mandrel 1 and collar bush 4 axially there is certain displacement amount, the elastic force of spring 5 makes mandrel 1 be in unidirectional extreme position all the time in mechanism's off working state.Described mandrel 1 is fixed together by pin 1 connection with spacing collar 3.Wherein: jump ring 6 can be substituted by nut, latch, rivet joint.
As shown in Figure 2,3, this patent in working order time, cylinder power source is threaded connection promotion collar bush 4 and moves, first the out-of-flatness end contact of the one side of spacing collar 3 and workpiece for measurement 8, the mandrel 1 connected thereafter through pin 7 stops mobile with spacing collar 3, and collar bush 4 then continues to move to, and crush seal ring 2, sealing ring 2 is made to deform, thus reaching the purpose of tensioner workpiece 8 endoporus closure.
As shown in Figure 4,5, mandrel 1, spacing collar 3 have a radial direction through hole, connect to form a structural member by pin 7.
As shown in Fig. 4, Fig. 6, in the end of mandrel, design has integral type step, for position limiting sealed ring, and ensures sealing property；Mandrel step place devises the circular arc mated with sealing ring, sufficiently sealed after making sealing ring tensioner.
The maximum cylindrical of collar bush, sealing ring, mandrel is slightly less than by closure inner hole of workpiece, and the big end position of mandrel is designed to wedge, it is achieved quickly guide-localization, it is simple to insert inner hole of workpiece before tensioner, it is ensured that the life-span of sealing ring.
Technique effect:
