To achieve these goals, the utility model adopts following technical scheme: a kind of thin-walled cone object processing inner supporting device, comprise pedestal, sleeve, guide pillar, adjusting bolt, straight pin, self adaptation round platform, stop screw and hold-down bolt, described pedestal adopts one end to be the hollow cylinder structure of opening, and sleeve set is on pedestal; Described guide pillar is positioned at base interior, guide pillar is connected by straight pin with sleeve, the part that straight pin passes on pedestal is provided with axially directed hole, is moved axially in foot guide hole by straight pin, limits sleeve and only can to move axially relative to pedestal and not rotatable; Described self adaptation round platform is arranged on sleeve overhanging end, and by stop screw limiting adaptive round platform axial freedom, the Circularhole diameter passed at self adaptation round platform upper limit screw is greater than the diameter of stop screw screw rod, and self adaptation round platform to be coordinated with stop screw by circular hole and has the radial free degree; Described self adaptation round platform is by hold-down bolt and sleeve compression fit.
Adjusting bolt outer cover between described guide pillar and pedestal is equipped with spring, makes adjusting bolt, guide pillar, sleeve and self adaptation round platform be in deflated state all the time by spring.
Described hold-down bolt has through hole in axial centre, and through hole is just to the nut of adjusting bolt.
The circumference of described self adaptation round platform is oat tail groove structure, in dovetail groove, be provided with rubber ring.
The beneficial effects of the utility model:
The utility model compared with prior art, meet the interior support requirement of thin-walled cone object, self adaptation laminating thin-walled cone object inwall can be realized, realize the ring-shaped bearing to thin-walled cone object and axially adjustment, extra clamping stress can not be produced in thin-walled cone object clamping process, the original shape of thin-walled cone object can be ensured, there is good damping effect simultaneously, effectively improve the machining accuracy of part.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of thin-walled cone object processing inner supporting device, comprise pedestal 1, sleeve 2, guide pillar 3, adjusting bolt 4, straight pin 5, self adaptation round platform 6, stop screw 7 and hold-down bolt 8, described pedestal 1 adopts one end to be the hollow cylinder structure of opening, and sleeve 2 is set on pedestal 1; It is inner that described guide pillar 3 is positioned at pedestal 1, guide pillar 3 is connected by straight pin 5 with sleeve 2, the part that straight pin 5 passes on pedestal 1 is provided with axially directed hole, is moved axially in pedestal 1 pilot hole by straight pin 5, limits sleeve 2 and only can to move axially relative to pedestal 1 and not rotatable; Described self adaptation round platform 6 is arranged on the overhanging end of sleeve 2, and by stop screw 7 limiting adaptive round platform 6 axial freedom, the Circularhole diameter passed at self adaptation round platform 6 upper limit screw 7 is greater than the diameter of stop screw 7 screw rod, and self adaptation round platform 6 to be coordinated with stop screw 7 by circular hole and has the radial free degree; Described self adaptation round platform 6 is by hold-down bolt 8 and sleeve 2 compression fit.
Adjusting bolt 4 outer cover between described guide pillar 3 and pedestal 1 is equipped with spring 9, makes adjusting bolt 4, guide pillar 3, sleeve 2 and self adaptation round platform 6 be in deflated state all the time by spring 9.
Described hold-down bolt 8 has through hole in axial centre, and through hole is just to the nut of adjusting bolt 4.
The circumference of described self adaptation round platform 6 is oat tail groove structure, is provided with rubber ring 10 in dovetail groove.
Below in conjunction with accompanying drawing, a use procedure of the present utility model is described:
Before to thin-walled cone object 13 clamping, inner supporting device 11 of the present utility model need be first installed, to be fixedly connected inner supporting device 11 by pedestal 1 and external stability seat 12, then hold-down bolt 8 to releasing orientation is adjusted, ensure that the radial free degree of self adaptation round platform 6 is adjustable, adjust adjusting bolt 4 makes guide pillar 3 be in maximum retracted position simultaneously, and after ensureing thin-walled cone object 13 clamping, guide pillar 3 has enough axial adjustment distances.
Thin-walled cone object 13 fixed by clamping, utilize spanner successively by the perforate of thin-walled cone object 13 small end, hold-down bolt 8 central through hole screws adjusting bolt 4, the control guide pillar 3 that screws by adjusting bolt 4 under spring 9 drag effect axially stretches out, thin-walled cone object 13 inwall until self adaptation round platform 6 reclines, and recline in process, self adaptation round platform 6 can by its radial free degree automatic aligning thin-walled cone object 13 center, determine that self adaptation round platform 6 puts in place by unexpected increase adjusting bolt 4 being screwed to moment of torsion, namely inner supporting device contacts with thin-walled cone object 13, hold-down bolt 8 is screwed finally by spanner, self adaptation round platform 6 is pressed on firmly on sleeve 2, complete thin-walled cone object 13 internal support, as shown in Figure 2.
Wherein, after rubber ring 10 installed by self adaptation round platform 6, that can avoid self adaptation round platform 6 pairs of thin-walled cone objects 13 of rigidity weighs damage wounded, can play damping shock absorption effect again, reduces the vibration that part adds man-hour.
Scheme in embodiment is also not used to limit scope of patent protection of the present utility model, does not allly depart from the equivalence that the utility model does and implements or change, and is all contained in the scope of the claims of this case.
