Description
Technical field
The utility model relates to the roller processing unit (plant), relates in particular to hole processing device in a kind of roller.
Background technology
It is to use means very widely in the middle of the industry-by-industry that roller-way is carried, and all adopts this means to come transporting steel billet as metallurgy industry.For driven roller wherein, after operation a period of time, must roll off the production line and carry out roll surface built-up welding, machining reparation and recycle realizing.Generally speaking, driven roller adopts the clamping method of a top one folder when machined turning two ends spindle nose and roll surface: an end uses entity that external diameter is consistent with driven roller spindle nose internal diameter silently, the fastening other end spindle nose of other end employing scroll chuck.When processing a certain end, just need the dismounting driven roller when needing the processing other end.The method of dismounting driven roller is: unload driven roller, be placed on and go up regularly with a diameter of phi 50mm, the steel pipe bar of length 2.5m, stretch into the driven roller center bore, knock bar with 12 pounds of sledge hammers again, pound out silently, reinstall the driven roller other end, last machine tooling.Silently driven in repeatedly and pounded out, not only time-consuming, consumption power, and silently fragile.After centre bore silently was destroyed, the quality of fit of itself and driven roller will reduce, and caused easily silently that the malalignment between centre bore and driven roller roll surface, the bearing guard cylindrical increases, and influenced the crudy of driven roller.
Summary of the invention
The utility model is intended to address the deficiencies of the prior art, and a kind of roller endoporus processing kink positioner is provided.The positioning device structure compactness that the utility model provides, easy to operate, centering precision is high and the clamping time is short.
The utility model is achieved in that a kind of roller endoporus processing kink positioner, comprises roller, and it is installed in an end of roller, and it comprises:
A tapering mandrel, the one end is for having externally threaded flat segments, and the other end is the cone that diameter progressively enlarges and can be positioned at described roller end-face hole;
A taper screws cover, and it is a tapered cup nut, but is inserted in the flat segments of tapering mandrel and links together with the screw thread move left and right with this tapering mandrel with its smaller diameter end;
A tapering elasticity kink, the inwall middle part is a flat segments, two ends have horn-like opening, the open interior wall is provided with tapped through hole, its flat segments is enclosed within on the described tapering mandrel, one end inner chamber skew wall cooperates with tapering mandrel cone appearance, and other end inner chamber skew wall cooperates with the tapering part appearance that taper screws cover, and Qi Bishang is provided with the elastic construction that makes described elasticity kink produce radial deformation.
Described roller endoporus processing kink positioner, elastic construction on the wall of described tapering elasticity kink is offer on the wall some and is provided with in length and breadth and disjoint groove is divided into the plurality of elastic slip with the wall of tapering elasticity kink that each slot length is greater than 2/3 tapering elasticity kink length.
Described roller endoporus processing kink positioner, the groove of described vertical setting has two, and they lay respectively at the flat segments two ends of tapering elasticity kink; And the groove of described horizontally set also has four, and they equidistantly are provided with at the flat segments upper edge of tapering elasticity kink circumference.
Described roller endoporus processing kink positioner, described taper elasticity kink has the radial-deformation of positive and negative 0.5mm.
Screw the radial-deformation that cover can be adjusted the elasticity kink by rotating elasticity kink of the present utility model and tapering.When the rotation of tapering nut is locked to the right, the tapering mandrel is relative motion also locking left in the pulling of screw thread, make the elasticity kink by two ends conical surface spreading, centering and tensioner workpiece, cone angle is more little in the locking process, extruding just tight more, when the tapering nut unclamps, when mandrel was done to promote motion relatively left, resilient sleeve was shunk, and takes out this positioner.
Before the driven roller processing,, can screw cover, tapering mandrel, make the expansion of elasticity kink as for a drive roller shaft endoporus close fit, machine tooling on the convenience by the rotation tapering with the positioner driven roller one end endoporus of packing into.In like manner, also for convenience detach.Use silently positioner of this elastic central spindle, not only install simple and easy, convenient disassembly, time saving and energy saving, and owing to increased location area, limited beating of elasticity kink plug and driven roller, guaranteed crudy.
