Abstract
The utility model discloses a dismantle convenient locating pin, include shank and the round pin head that is located shank one end, the round pin head is kept away from on the one end terminal surface of shank with the axis of shank is the center and follows the shank axis direction is equipped with the screw through -hole to the indent, screw -thread fit has the double -screw bolt in the screw thread through -hole, the double -screw bolt is close to the one end terminal surface fovea superior of round pin head is equipped with convenient messenger the rotatory interior hexagonal hole of double -screw bolt. The utility model discloses simple structure, convenient to use is laborsaving, through the ejecting shank mode of double -screw bolt, has avoided causing the damage when extracting.
Description
Technical field
The utility model relates to a kind of alignment pin, is specifically related to a kind of alignment pin of convenient disassembly.
Background technology
In Digit Control Machine Tool processing, when workpiece is fixed on machine tooling platform, need alignment pin to position installation to workpiece. Owing to being interference fit between alignment pin and locating hole, owing to there is no special extracting tool, making to extract alignment pin not only wastes time and energy, but also usually can damage alignment pin, it is scrapped, and even damage processing platform, causes larger waste.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, easy to use laborsaving, do not cause the alignment pin of the convenient disassembly of any damage.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of alignment pin of convenient disassembly, comprise shank and the plunger that is positioned at shank one end, it is characterized in that: described plunger is away from being concaved with tapped through hole on one end end face of described shank centered by the axis of described shank and along described shank axis direction, described tapped through hole screw-internal thread fit has double-screw bolt, is concaved with the inner hexagonal hole that conveniently makes described double-screw bolt rotation on one end end face of described double-screw bolt near described plunger.
In the utility model, when alignment pin is dismantled, by the tapped through hole at plunger top, utilize on the inner hexagonal hole of instrumental purpose on double-screw bolt top, because shank is stuck in locating hole, rotation double-screw bolt moves its bottom towards locating hole. After double-screw bolt touches locating hole bottom, continue rotation double-screw bolt, double-screw bolt cannot move, the radial load of the hand of spiral will reaction on shank, shank is moved outside locating hole until shank can easily be extracted in locating hole. It is simple in structure, easy to use laborsaving, can not cause any damage.
As optimization, the outer surface of described shank is provided with from the one end away from described plunger towards the spiral air-conducting groove extending near an extreme direction of described plunger. General locating hole is all blind hole, and between alignment pin and locating hole, is the tight fit that interference is connected, and when shank is outwards extracted, causes locating hole internal gas pressure to reduce, and then makes shank be difficult to extract in locating hole. And spiral air-conducting groove on shank outer surface can will be in communication with the outside in locating hole, make locating hole internal gas pressure with extraneous consistent, shank just can be extracted smoothly in locating hole like this.
As optimization, described double-screw bolt is away from one end of described plunger by the flexible rubber blanket that is rotatably assorted along the outwardly directed rotating shaft of described double-screw bolt axis direction, and described resilient rubbber cushion cross section full-size is less than the internal diameter of described tapped through hole. When double-screw bolt is connected at the bottom of locating hole hole, its rotation can make both cause certain wearing and tearing, and can send ear-piercing abnormal sound. And resilient rubbber cushion its cushioning effect between at the bottom of double-screw bolt and locating hole hole, at the bottom of avoiding double-screw bolt directly to touch locating hole hole.
In sum, the beneficial effects of the utility model are: the utility model is simple in structure, easy to use laborsaving, eject shank mode by double-screw bolt, have avoided causing damage in extracting.
Brief description of the drawings
In order to make object, technical scheme and the advantage of utility model clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the alignment pin of the convenient disassembly in this detailed description of the invention, comprise shank 1 and the plunger 2 that is positioned at shank 1 one end, described plunger 2 is away from being concaved with tapped through hole 3 on one end end face of described shank 1 centered by the axis of described shank 1 and along described shank 1 axis direction, described tapped through hole 3 screw-internal thread fit have double-screw bolt 4, on one end end face of described double-screw bolt 4 near described plunger 2, are concaved with the inner hexagonal hole 5 that conveniently makes described double-screw bolt 4 rotate.
In this detailed description of the invention, the outer surface of described shank 1 is provided with from the one end away from described plunger 2 towards the spiral air-conducting groove 6 extending near an extreme direction of described plunger 2.
In this detailed description of the invention, described double-screw bolt 4 is away from one end of described plunger 2 by the flexible rubber blanket 7 that is rotatably assorted along the outwardly directed rotating shaft of described double-screw bolt 4 axis direction, and described resilient rubbber cushion 7 cross section full-sizes are less than the internal diameter of described tapped through hole 3.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
