Abstract
The utility model provides a kind of mandrel tensioning apparatus, comprises mandrel, the chuck be enclosed within outside mandrel, blind flange, pull bar, O type circle, and mandrel outer surface is provided with tapering inclined-plane, makes mandrel be clamped in chuck, blind flange by spindle Lock in chuck and blind flange; Mandrel front end is provided with groove, mandrel front inner surface is provided with tapering inclined-plane, and pull bar is arranged in mandrel, and one end of pull bar is provided with tapering inclined-plane, is used for matching with the tapering inclined-plane on mandrel front inner surface, and the other end of pull bar is provided with screw thread; Part in mandrel outer surface between tapering inclined-plane and groove is provided with O type ring recess, and O type circle is arranged in O type ring recess.This kind of mandrel tensioning apparatus can make mandrel be clamped at firmly in chuck, adapt to higher speed more quietly and rotate processing, the axiality of better guarantee mandrel and chuck, can also workpiece effectively on tensioning mandrel, workpiece is fixed on mandrel firmly, also better ensure that the axiality of Workpiece internal-external circle simultaneously.
Description
Technical field
The utility model relates to a kind of device making mandrel tensioning workpiece.
Background technology
Mandrel is a kind of a kind of positioning fixture being used for fixing inner bore of part or special shape groove, sometimes also coordinates thimble etc. to use together.Lathe is generally used for being processed with the revolving meber that there is groove at endoporus or center.Although current mandrel can play the effect of positioning fixture, internal-external circle concentricity is required that higher workpiece not easily ensures, and workpiece is enclosed within mandrel, and fastness and stability neither be fine.
Utility model content
For solving the problem, the utility model provides a kind of mandrel tensioning apparatus, can make mandrel tensioning workpiece firmly, and adapt to larger rotating speed and rotate, its technical scheme adopted is as follows:
A kind of mandrel tensioning apparatus, comprise mandrel and be enclosed within the chuck outside mandrel, described mandrel tensioning apparatus also comprises blind flange, pull bar, described mandrel outer surface is provided with tapering inclined-plane, mandrel can be made to be clamped in better in chuck, make it like this under higher rotation speed, mandrel also can keep stable rotation, blind flange by spindle Lock in chuck and blind flange; Described mandrel front end is provided with groove, be used for increasing elastic force, tensioning workpiece, mandrel front inner surface is provided with tapering inclined-plane, described pull bar is arranged in mandrel, one end of pull bar is provided with tapering inclined-plane, is used for matching with the tapering inclined-plane on mandrel front inner surface, and the other end of pull bar is provided with screw thread, can connect with cylinders, when cylinder pulls pull bar, pull bar relies on tapering inclined-plane tensioning mandrel, and then makes mandrel by the workpiece of groove tensioning sleeve on mandrel.
Further, described mandrel tensioning apparatus also comprises O type circle, part in mandrel outer surface between tapering inclined-plane and groove is provided with O type ring recess, described O type circle is arranged in O type ring recess, O type circle can increase the resistance that workpiece slides on mandrel, make workpiece more firm, be fixed on mandrel more quietly, adapt to higher rotation speed processing, also better ensure that the axiality of Workpiece internal-external circle simultaneously.
Further, the tapering on the tapering inclined-plane in described mandrel outer surface is 20o.
Further, the tapering on the tapering inclined-plane on described mandrel front inner surface is 10o.
By the realization of technique scheme, the utility model the mandrel tensioning apparatus of confession mandrel can be made to be clamped at firmly in chuck, adapt to higher speed more quietly and rotate processing, the axiality of better guarantee mandrel and chuck, can also workpiece effectively on tensioning mandrel, workpiece is fixed on mandrel firmly, also better ensure that the axiality of Workpiece internal-external circle simultaneously.
Accompanying drawing explanation
Fig. 1 provides by the utility model the structural representation of mandrel tensioning apparatus;
Fig. 2 is the structural representation of mandrel.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of mandrel tensioning apparatus, comprise mandrel 1, the chuck 2 be enclosed within outside mandrel 1, blind flange 3, pull bar 4, O type circle 5, the outer surface of mandrel 1 is provided with tapering inclined-plane 11, mandrel 1 is made to be clamped in chuck 2, its tapering is 20o, and mandrel 1 is locked in chuck 2 and blind flange 3 by blind flange 3; Mandrel 1 front end is provided with groove 12, and mandrel 1 front inner surface is provided with tapering inclined-plane 13, and its tapering is 10o, pull bar 4 is arranged in mandrel 1, one end of pull bar 4 is provided with tapering inclined-plane 41, is used for matching with the tapering inclined-plane 13 on mandrel 1 front inner surface, and the other end of pull bar 4 is provided with screw thread; Part on mandrel 1 outer surface between tapering inclined-plane 11 and groove 12 is provided with O type ring recess 14, O type circle 5 and is arranged in O type ring recess 14.
