Abstract
The utility model belongs to aircraft tool manufacturing technology, and relates to a locating pin of a blind hole. The locating pin of the blind pole comprises a pin body (1) of a cylindrical shape, and is characterized in that a threaded hole (2) axially penetrates through two end surfaces of the pin body (1) in the center of the pin body (1). The locating pin of the blind hole is convenient to install and take out. Gas in the blind hole is capable of being discharged from the threaded hole (2) smoothly when the locating pin of the blind hole is installed, when the locating pin of the blind hole is taken out, a bolt is screwed into the threaded hole, so that the locating pin of the blind hole can be conveniently taken out when the bolt is taken as a carrier.
Description
Technical field
The utility model belongs to aircraft frock manufacturing technology, relates to a kind of blind hole locating stud.
Background technique
Locating stud in the existing aircraft frock is the entity straight pin.Its shortcoming is: the first, difficult installation.In aircraft frock manufacture process, when often taking place, blind hole locating stud entering positioning hole ejected situation about can not accurately locate by residual gas.The second, take out difficulty.When the aircraft product structure is changed, need take out the locating stud that is installed in the blind hole, because locating stud and blind hole adopt interference fit, take out very difficulty, often cause the damage of aircraft tool locating part.
Summary of the invention
The purpose of the utility model is: a kind of blind hole locating stud of installing and taking out be convenient to is provided.
The technological scheme of the utility model is: a kind of blind hole locating stud, comprise columniform shank 1, and it is characterized in that; A tapped hole 2 that connects 1 two end faces of shank is vertically arranged at the center of shank 1; Maximum inner diameter d=(0.2～0.5) D of tapped hole 2, D is the external diameter of shank 1, unit is mm.
The utility model has the advantages that: be convenient to install and take out.During installation, the gas in the blind hole can be discharged from tapped hole smoothly; During taking-up, screw is screwed into tapped hole, as push rod, can takes out the blind hole locating stud easily with screw.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Explain further details in the face of the utility model down.Referring to Fig. 1, a kind of blind hole locating stud comprises columniform shank 1; It is characterized in that a tapped hole 2 that connects 1 two end faces of shank is vertically arranged at the center of shank 1, maximum inner diameter d=(0.2～0.5) D of tapped hole 2; D is the external diameter of shank 1, and unit is mm.
When aircraft product change position, hole; Be screwed into common screw in the tapped hole 2 of shank 1; Pass through rotary screw; Make screw end head hold out against the bottom of the positioning hole of aircraft frock, continue rotary screw, the blind hole locating stud can climb away positioning hole gradually along the opposite direction that screw rod advances from the positioning hole of aircraft frock.
