The content of the invention

The aviation drying existed to solve above-mentioned prior art dismantles difficulty greatly and easily in unloading process to correlation Close part causes the technical problem of damage, and the utility model proposes a kind of provision for disengagement of aerospace seal drying.

The technical solution of the utility model is：

A kind of provision for disengagement of the aerospace seal drying, it is characterised in that：Including taper expansion block, ring washer is connected, it is recessed Shape block, expansion set, cinch bolt, locking nut, adjustable handle；

It is the conical surface on the outside of the expansion set, expansion set axial centre is provided with the taper hole with outside conical surface opposite direction；

The cinch bolt passes through expansion set axial centre taper hole, and is provided with cinch bolt locking nut；Swelling Bolt one end is axially connected by spill block and connection ring washer with taper expansion block, and the cinch bolt other end connects with adjustable handle Connect；

The taper expansion block is arranged in expansion set axial centre taper hole, and the conical surface and expansion set axial centre on the outside of taper expansion block Taper hole cone match.

Further preferred scheme, a kind of provision for disengagement of aerospace seal drying, it is characterised in that：The expansion set The outside conical surface is equipped with rubber blanket.

Further preferred scheme, a kind of provision for disengagement of aerospace seal drying, it is characterised in that：The swelling Bolt leading portion is connected with taper expansion block using spherical.

Further preferred scheme, a kind of provision for disengagement of aerospace seal drying, it is characterised in that：It is described swollen Dimensions is cased with to adapt to the drying of different-diameter.

Further preferred scheme, a kind of provision for disengagement of aerospace seal drying, it is characterised in that：It is described adjustable Handle is foldable.

Beneficial effect

The utility model makes cinch bolt move in the axial direction by locking nut, and then expansion set is radially expanded , so that drying inwall be adjacent to, rotation adjustable handle can dismantle drying.The utility model have it is simple in construction, It is easy to use, economical and practical, the advantages of can be widely applied to the dismounting of Aero-Space class drying.

Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description In become obvious, or by it is of the present utility model practice recognize.

Brief description of the drawings

Of the present utility model above-mentioned and/or additional aspect and advantage will from description of the accompanying drawings below to embodiment is combined Become substantially and be readily appreciated that, wherein：

Fig. 1 is the sectional view of the utility model structural representation.

Fig. 2 is the sectional view of the utility model use state structural representation.

Wherein：1st, taper expansion block；2nd, ring washer is connected；3rd, spill block；4th, expansion set；5th, cinch bolt；6th, locking nut；7、 Adjustable handle；8th, drying.

Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width Degree ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer ", The orientation or position relationship of the instructions such as " clockwise ", " counterclockwise " be based on orientation shown in the drawings or position relationship, be only for It is easy to description the utility model and simplifies describe, rather than to indicate or imply that signified device or element must have specific Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.

As depicted in figs. 1 and 2, the provision for disengagement for the aerospace seal drying that the present embodiment is proposed, including taper expansion block 1, Connect ring washer 2, spill block 3, expansion set 4, cinch bolt 5, locking nut 6, adjustable handle 7；It is the conical surface on the outside of the expansion set, it is swollen Set axial centre is provided with the taper hole with outside conical surface opposite direction；The cinch bolt pass through expansion set axial centre taper hole, and Locking nut is installed on cinch bolt；Cinch bolt one end is axially connected by spill block and connection ring washer with taper expansion block Connect, the cinch bolt other end is connected with adjustable handle；The taper expansion block is arranged in expansion set axial centre taper hole, and tapered expansion The conical surface and expansion set axial centre taper hole cone match on the outside of block.

In the present embodiment, cinch bolt is moved in the axial direction by locking nut, and then make expansion set radially Expansion, so that drying inwall be adjacent to, rotation adjustable handle can dismantle drying.

Employ the utility model proposes drying provision for disengagement can effectively protect drying in unloading process not Sustain damage.The expansion set of the provision for disengagement has plurality of specifications to adapt to the drying of different-diameter；The adjustable hand of the provision for disengagement The foldable adjustment of handle is to facilitate the operation of small space；The expansion set surface of the provision for disengagement increases friction by annular knurl Quenching Treatment Power and service life；The expansion set surface of the provision for disengagement can also increase by one layer of rubber blanket to protect drying inwall；The dismounting is filled Cinch bolt front end is put to can be achieved to be automatically positioned for spherical connection with taper expansion block；The device can be additionally used in the inner hole parts such as bearing Dismounting, using pin removal principle by weight be enclosed on cinch bolt impact adjustable handle just may be used.

The utility model has simple in construction, easy to use, economical and practical, can be widely applied to Aero-Space class drying Dismounting and interior hole type parts the advantages of dismantle.

Although embodiment of the present utility model has been shown and described above, it is to be understood that above-described embodiment is Exemplary, it is impossible to it is interpreted as to limitation of the present utility model, one of ordinary skill in the art is not departing from the utility model Principle and objective in the case of above-described embodiment can be changed in the range of the utility model, change, replace and Modification.
