Because awl tube is a thin-wall part, in use will bear high-intensity stress alternation, the material of choosing is that intensity is higher but carbon steel that antiseptic property is relatively poor, annular seal space is in the moist environment for a long time, taper fit face easy-to-rust, the time one is long, and the awl tube may be because of serious corrosion adhesion locking.
Therefore, no matter be to use from the production or the maintenance of product, a kind of convenient and reliable method for dismounting all should be arranged, the vitality of coming enhanced products.
Summary of the invention
The present invention is directed to the dismounting difficult problem in the large-scale thin-wall wimble barrel production assembling and use after non-dismountable risk, design a kind of external anchor clamps, guarantee that the awl tube can both dismantle at any time smoothly.
The technical scheme that technical solution problem of the present invention is adopted is:
A kind of large-scale thin-wall wimble barrel disassembling clamper comprises outer shroud, two semicircular ring, spanner, end face thrust bearing, adjusts circle; Described two semicircular ring embed in outer shroud one end after being merged into the full circle ring, fasten the step of the dumb-bell shape stepped ramp type cylinder small end outer surface of large-scale awl tube; The adjustment circle is threaded with the outer shroud other end; Described spanner passes on the swivel nut of adjusting circle and large-scale awl tube annular seal space and is connected; End face thrust bearing one side is near adjusting circle, and another side is near the swivel nut of large-scale awl tube annular seal space.
The present invention is by dissolving the weak link of the power of transmitting in the original product, and directly the thrust with screw mechanism effectively is delivered on the awl tube, reaches the purpose of dismounting awl tube, and simple in structure, convenient disassembly can use repeatedly, and its technique effect is as follows:
1, adopted the end face thrust bearing, can eliminate spin friction moment, improved the power transmission efficiency, prevented that the component surface processing layer from fraying;
2, adopted two semicircular ring to add the locking mechanism of an outer shroud, set up the connected mode of power transmission, solved the strength problem that thin cylinder connects for the concentric reducer face of cylinder.
