Abstract
The utility model discloses an interference screw bolt removing tool, aiming to provide the removing tool for separating an interference screw bolt from a structural member. The interference screw bolt removing tool comprises a casing and a nail pulling threaded rod. The casing is of hollow structure with an opening at the lower end, and the upper end of the casing is provided with a center hole. The upper end of the nail pulling threaded rod penetrates through the center hole of the casing and is relatively fixed with the casing through a screw nut, and the lower end of the nail pulling threaded rod is an open threaded rod positioning groove. The utility model has simple structure and convenient use, needs not drill a hole at the head of the screw bolt, and can not damage the hole and adjacent products.
Description
Technical field
The utility model relates to machine-building instrument class, particularly a kind of nail instrument of tearing open of interfering bolt that decomposes from structural member.
Background technology
Being threaded is one of main type of attachment of aircaft configuration, is mainly used in the connection at the main load-carrying construction of aircraft position.After bolt is installed, exist defective undesirable if find bolt or nut, just must decompose, but being threaded of interference engagement, because of having bigger amount of interference between bolt nail bar and the hole, bolt decomposes difficulty, and the normal at present method of using is after decomposing nut, knock bolt foot piece termination with riveting gun, until bolt is got from the hole.Make in this way, make bolt nail bar produce distortion easily in the process of being knocked, jumping-up makes that the amount of interference between bolt and the hole becomes bigger, and then is stuck in the hole, causes taking out difficulty more.Another kind method is to use drill bit to hole at bolt head, bolt head is separated with the nail bar, use punching pin that bolt is got then, because the bolt material overwhelming majority is a titanium alloy, the boring difficulty, must be at the guide hole of a small-bore of the center of bolt head subdrilling, according to the diameter that will decompose bolt, select the drill bit slightly littler that the hole is enlarged then, bolt head is separated with the nail bar than the diameter of bolt, and very easy that hole drill is inclined to one side in boring procedure, damage hole and proximity structure.In the prior art, happen occasionally owing to decomposing the difficult situation that causes structure to be scrapped of bolt.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and a kind of nail instrument of tearing open of interfering bolt that decomposites from structural member is provided.
Interfere bolt to tear the nail instrument open, contain housing and nail pulling screw rod, housing is a kind of hollow-core construction of lower ending opening, and the upper end of housing is provided with centre bore, the upper end of nail pulling screw rod passes the centre bore of housing and by nut and housing relative fixed, the lower end of nail pulling screw rod is the screw rod locating slot of an opening.
The housing that to interfere bolt to tear the nail instrument open during use is pressed on the structure of tearing the nail instrument open, the nail bar of interfering bolt is fixed on the locating slot of nail pulling screw rod, be installed on the nut of tearing nail instrument nail pulling screw rod rear portion open by rotation, make the nail pulling screw rod drive bolt that is stuck on the bolt nail bar move upward together, thereby reach the purpose that safe and reliable dismounting need be changed bolt with respect to housing.
In order to make the nail pulling screw rod stable, on housing, be provided with the gathering sill of nail pulling screw rod operation, the nail pulling screw rod is provided with corresponding guide finger.
In order to prevent to interfere bolt to tear nail instrument damage product surface open, the lower end of housing is provided with one deck neonychium.
For make remove to interfere bolt more laborsaving on nail pulling screw rod top nut and housing between be connected with single thrust bearing.
Compared with prior art, the beneficial effects of the utility model are simple in structure, and are easy to use and need not hole at bolt head, also can not cause damage to hole and adjacent product.

Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:
Referring to accompanying drawing 1, interfere bolt to tear the nail instrument open and contain housing 1 and nail pulling screw rod 2, housing 1 is a kind of hollow-core construction of lower ending opening, the upper end of housing 1 is provided with centre bore, the upper end of nail pulling screw rod 2 is passed the centre bore of housing and is passed through nut 4 and housing 1 relative fixed, the lower end of nail pulling screw rod 2 is screw rod locating slots of an opening, and the fluting that partly matches with the nail bar of interfering bolt 9 is all arranged on the bottom of this screw rod locating slot and the side, can interfere bolt 9 to be stuck in the notch of locating slot.
Housing 1 is provided with the gathering sill of nail pulling screw rod 2 operation, and nail pulling screw rod 2 is provided with corresponding guide finger 6, and the diameter of guide finger 6 matches with gathering sill on the housing 1, and the structure of nail pulling screw rod 2 lower ends matches with the internal diameter of housing 1.In order to prevent to interfere bolt to tear nail instrument damage product surface open, the lower end of housing 1 is provided with one deck neonychium 8, and housing 1 is connected by screw 7 with neonychium 8.To interfere bolt more laborsaving in order making to remove, to be connected with single thrust bearing 3 between the nut 4 on nail pulling screw rod 2 tops and the housing 1.Be connected with packing ring 5 between nut 4 and the single thrust bearing 3.
User mode as shown in Figure 1, at first cleaning interfere bolt 9 around, divide and take off original hold-down nut of interfering bolt; Then knock the afterbody of interfering bolt 9 gently, make and interfere the head of bolt 9 to be higher than structure 10 surfaces; Block on the nail bar of interfering bolt 9 with the screw rod locating slot on the nail pulling screw rod 2 then, the size of the bolt locating slot of nail pulling screw rod 2 matches with the diameter dimension of interfering bolt 9; At last with spanner rotation nut 4, drive nail pulling screw rod 2 simultaneously and interfere bolt 9 to move upward together, until interfering bolt 9 from centre bore, to be extracted with respect to housing.
