Abstract
The utility model discloses a conveniently removable locating pin which comprises a locating shaft, an end shat, a concave shaft, a convex shaft, a transition shaft and a tail shaft that are integrally connected, wherein the locating shaft, the end shaft and the tail shaft are circular shafts; the concave shaft is a concave circular shaft, the convex shaft is a convex circular shaft; the transition shaft is an R-shaped transition shaft connecting the convex shaft and the tail shaft; the manufacture size of the outer diameter of the end shaft is more than that of the outer diameter of the locating shaft and that of the maximum outer diameter of the convex shaft; and the manufacture size of the outer diameter of the tail shaft is more than that of the maximum outer diameter of the convex shaft. Because the concave shaft and the convex shaft are manufactured into shapes suitable for being held by hands of an operator, the locating shaft is convenient for stress; and because the end shaft and the tail shaft limit the front and rear sliding of the palm, the locating pin is convenient for being removed in the work and avoids damaging the locating hole and the loosing deviation of the assembling position.
Description
Technical field
The utility model belongs to the frock manufacturing technology, relates to a kind of locating stud of being convenient to plug.
Background technique
Existing application in the locating stud of aircraft frock manufacturing pin part adopt the light face directly type or annular knurl directly type.In the frock connection procedure of reality, interconnect part positioning hole position and often have certain dislocation deviation, cause locating stud to insert and when withdrawing from working resistance become big, because the light face directly directly can not be fitted the type locating stud type or annular knurl with palm fully, locating stud is stressed limited, and locating stud is less for the restriction that endwisely slips of palm, the easy slippage of hand, householder methods such as therefore common needs use that external force is beaten are finished the insertion of locating stud and are withdrawed from, cause locating stud moment to clamp-on easily and interconnect the part positioning hole, the link positioning hole is damaged or the loosening deviation of rigging position.
Summary of the invention
The purpose of this utility model: provide a kind of and be easy to hold with a firm grip, limit slippage, the locating stud being convenient to plug.
The technical solution of the utility model is: a kind of locating stud of being convenient to plug is made of positioning shaft 1, end axle 2, recessed axle 3, protruding axle 4, transition axis 5 and tailing axle 6 one; It is characterized in that positioning shaft 1, end axle 2, tailing axle 6 are circular shaft; Recessed axle 3 is a spill circular shaft, and protruding axle 4 is a convex circular shaft; Transition axis 5 is for connecting the R type transition axis of protruding axle 4 and tailing axle 6; End axle 2 external diameter manufacturing dimensions are greater than the external diameter manufacturing dimension of positioning shaft 1 and the maximum outside diameter manufacturing dimension of protruding axle 4; Tailing axle 6 external diameter manufacturing dimensions are greater than the maximum outside diameter manufacturing dimension of protruding axle 4.
Recessed axle 3 is fabricated to the shape that suitable operator holds hand-type with a firm grip with protruding axle 4.
The utility model has the advantages that: because the recessed axle of locating stud is fabricated to the shape that suitable operator holds hand-type with a firm grip with protruding axle, be convenient to stressed, again because end axle and tailing axle have limited the front and back slip of palm, therefore locating stud is easy to hold with a firm grip, be convenient to plug at work, has avoided positioning hole to damage and the loosening deviation of rigging position.
Description of drawings
Fig. 1 is the schematic representation of the utility model locating stud.
Embodiment
Below the utility model is described in further details.
A kind of locating stud of being convenient to plug that is used for tool locating is made of positioning shaft 1, end axle 2, recessed axle 3, protruding axle 4, transition axis 5 and tailing axle 6 one.
Described positioning shaft 1, end axle 2, tailing axle 6 are circular shaft; Recessed axle 3 is a spill garden axle, and protruding axle 4 is a convex garden axle; Transition axis 5 is for connecting the R type transition axis of protruding axle 4 and tailing axle 6; End axle 2 external diameter manufacturing dimensions are greater than the external diameter manufacturing dimension of positioning shaft 1 and the maximum outside diameter manufacturing dimension of protruding axle 4; Tailing axle 6 external diameter manufacturing dimensions are greater than the maximum outside diameter manufacturing dimension of protruding axle 4.
The spill cambered surface manufacturing of described recessed axle 3 is shaped as that suitable operator's thumb and forefinger are held with a firm grip, the shape of clamping; The convex-shaped arc surface manufacturing of protruding axle 4 is shaped as that suitable operator's middle finger, the third finger, little finger of toe and palm are held with a firm grip, the shape of clamping.
Working principle of the present utility model is:
When inserting the positioning shaft 1 of locating stud in the part positioning hole, because operator's thumb and forefinger can effectively be held with a firm grip, the recessed axle 3 of clamping locating stud, operator's middle finger, the third finger, little finger of toe and palm can effectively be held with a firm grip, the protruding axle 4 of clamping locating stud, the end axle 2 of locating stud can effectively stop recessed 3 operator's of the locating stud of holding with a firm grip thumb and forefinger slippage forward vertically, so very convenient in the positioning shaft 1 insertion part positioning hole.
When the positioning shaft 1 of locating stud is extracted in the part positioning hole, because operator's thumb and forefinger can effectively be held with a firm grip, the recessed axle 3 of clamping locating stud, operator's middle finger, the third finger, little finger of toe and palm can effectively be held with a firm grip, the protruding axle 4 of clamping locating stud, the tailing axle 6 of locating stud can effectively stop operator's middle finger, the third finger, little finger of toe and the palm of protruding axle 4 of the locating stud of holding with a firm grip vertically to retrolisthesis, so that positioning shaft 1 is extracted in the part positioning hole is very convenient.
