At present at some pressure cylinders, as oil hydraulic cylinder, in the mechanical structures such as pneumatic cylinder, in order to play good positioning action and seal action to the axis and shaft parts on cylinder body, often need to carry out clamping position by shearing ring device to axis and shaft parts, but in use find, shearing ring device axis and shaft parts is positioned time, owing to lacking necessary restraining ability, often comparatively serious impression is caused to axis and shaft parts surface, destroy the surface quality of axostylus axostyle type component, serious equipment failure is even caused time serious, the usability of shearing ring device has been had a strong impact on from two, therefore, in order to improve stable equipment operation, strengthen the reliability that shearing ring device uses, in the urgent need to improving existing shearing ring device, to make it while possessing and providing reliably sealing and the ability of compression, avoid causing damage to axis and shaft parts surface.
Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of tension protective type shearing ring locking mechanism, constant chucking power and good sealability can be provided to axostylus axostyle type component on the one hand, effectively can prevent from causing because clamping force is excessive on the other hand axostylus axostyle type component being carried out to clamping while and damage is caused to axostylus axostyle type component structure.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of tension protective type shearing ring locking mechanism, comprise positioning disk, compact heap, Returnning spring and elasticity positioning block, positioning disk is cylindrical, its internal surface establishes locating slot, compact heap at least 4 pieces and all claim arc-shaped, compact heap successively the first connect after, the concentric positive circle distributed with positioning disk can be formed, compact heap is distributed in locating slot, and be slidably connected with locating slot, and compact heap mid point overlaps with locating slot center line, elasticity positioning block is all established between locating slot internal surface and compact heap outer surface and between adjacent compact heap surface of contact, compact heap outer surface midpoint establishes connecting screw hole, connecting screw hole both sides establish at least one mounting hole respectively, mounting hole is with connecting screw hole axisymmetrical, and connecting screw hole, mounting hole axis and locating slot center line are distributed in same plane, on locating slot with on connecting screw hole and mounting hole corresponding position, also connecting screw hole and mounting hole are set respectively, compact heap establishes drive screw by connecting screw hole, drive screw one end is connected with compact heap, the other end is positioned at outside positioning disk, Returnning spring is arranged in mounting hole, and one end and positioning disk offset, the other end and compact heap offset, contiguous block is separately established in positioning disk upper-end surface and lower end surface, contiguous block and positioning disk coaxially distribute, and its outer surface establishes connecting thread.
Further, described compact heap internal surface separately establishes elasticity friction-proof piece.
Further, separately connected by elastic connecting strip between described compact heap.
Further, described contiguous block and positioning disk are integral type structure.
Structure of the present invention is simple, reasonable in design, constant chucking power and good sealability can be provided to axostylus axostyle type component on the one hand, effectively can prevent from causing because clamping force is excessive on the other hand axostylus axostyle type component being carried out to clamping while and damage is caused to axostylus axostyle type component structure.
