Description
Technical field
The keeper in mechanical field is the utility model is related to, more particularly to a kind of alignment pin.
Background technology
Those skilled in the art both knows about, and at present, alignment pin is most commonly that in the keeper in mechanical field.Referring to
Shown in Fig. 1 and Fig. 2, a kind of common alignment pin, including shank 10 made of metal material, it is provided with the top of the shank 10 upper
Narrow lower wide guide part A, guide part A are used for being oriented in the use of alignment pin, facilitate on shank 10 and correlated parts
Positioning hole be attached.In the presence of the surface of correlated parts of easily wounding and its fixed when this alignment pin is used for following two situations
The technical problem in position hole；
The first situation is that the bottom of the alignment pin is connected to the top of larger, heavier-weight the part of a volume
Afterwards, then the part is held up by the positioning on the top of the alignment pin and the bottom of larger, heavier-weight the part of another volume
When hole is attached realization positioning, if operating space is smaller, the top of shank 10 made of metal material and its top with
The upper wedge angle a1 and lower wedge angle a2 that guide part A and shank 10 and guide part A connection place is formed easily wound or scratched
Positioning hole and its bottom surface on the bottom of larger, heavier-weight the part of another volume, so as to cause alignment quality poor
With it is unstable and then reduce using effect and the life-span of larger, heavier-weight the part of another volume.
Second of situation is to be inverted when by the alignment pin, i.e., by shown in its Fig. 1 top down, its is bottom-up
After its bottom to be connected to the bottom of larger, heavier-weight the part of a volume on ground, then the part is held up by the top of alignment pin
When portion is attached realization positioning with the positioning hole on the top of larger, heavier-weight the part of another volume, if operation
Space is smaller, then the top of shank 10 made of metal material and its top and guide part A and shank 10 and guide part A company
Meeting the upper wedge angle a1 and lower wedge angle a2 of place formation, similarly easily to wound or scratch another volume larger, heavier-weight
Positioning hole and its top surface on the top of part.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of preferable and more stable alignment pin of alignment quality.
In order to solve the above technical problems, the utility model adopts the following technical scheme that；
A kind of alignment pin, including shank made of metal material, up-narrow and down-wide guide part is provided with the top of the shank,
It is characterized in that：Also include the protective made of softer elastomeric material, the protective includes connecting portion and by the connection
Extend radially outwardly at the top of portion and its maximum outside diameter is less than or equal to the top of the maximum outside diameter of shank, its lower surface and shank
The protection portion to fit, the top of the shank are provided with the connection blind hole extended longitudinally downward, the connecting portion of the protective with
The connection blind hole interference fit of shank.
After taking said structure, the bottom of alignment pin is connected either in the case of the first described in the background
Behind the top of larger, heavier-weight the part of a volume, then the part is held up by the top of the alignment pin and another individual
Positioning hole on the bottom of larger, heavier-weight the part of product is attached realization positioning, even if operating space is smaller, alignment pin
What positioning hole and its bottom on the bottom of larger with another volume, heavier-weight part were in contact is by softer elastic material
Protection portion made of material on protective, and the top and its top of shank made of metal material and guide part and shank with
Guide part connection place formed upper wedge angle and lower wedge angle all without with larger, heavier-weight the part of another volume
Positioning hole and its bottom surface on bottom are in contact, then, the top and its top of shank made of metal material and guide part with
And the connection place of shank and guide part formed upper wedge angle and lower wedge angle will not wound or scratch another volume it is larger,
Positioning hole and its bottom surface on the bottom of the part of heavier-weight.Thus, alignment quality preferably and stably and ensures this another
Volume is larger, the using effect of the part of heavier-weight and life-span.Regardless of being second of situation described in the background
The alignment pin is inverted, bottom-up its bottom is connected to larger, heavier-weight the part of a volume its
Behind bottom, then the part is held up by the top of alignment pin with determining on the top of larger, heavier-weight the part of another volume
Position hole is attached realization positioning, even if operating space is smaller, alignment pin and larger, heavier-weight the part of another volume
It is that positioning hole and its top surface on top are in contact and by the protection portion made of softer elastomeric material on protective, and it is golden
Belong to the top of shank made of material and its top and the upper wedge angle of the connection place formation of guide part and shank and guide part
Positioning hole and its top surface that then also will not be on the top of part larger with another volume, heavier-weight with lower wedge angle connect
Touch.Then, the top of shank made of metal material and its top and guide part and the connection place shape of shank and guide part
Into upper wedge angle and lower wedge angle also will not wound or scratch and determine on the top of larger, heavier-weight the part of another volume
Position hole and its top surface, so that alignment quality is preferable and more stable and then ensures that another volume is larger, heavier-weight
The using effect of part and life-span.
Further, the diameter of the connecting portion of the protective generally upper part is more than the stairstepping of the diameter of lower part
Cylinder or cone, correspondingly, the connection blind hole generally upper part extended longitudinally downward that the top of the shank is provided with
Diameter be more than lower part diameter stairstepping cylindrical hole or conical bore.This causes on connecting portion and shank on protective
The processing for connecting the connection blind hole on the connecting portion and shank that connect on more solid and reliable and protective of blind hole is fairly simple
Easily.
Further, up-narrow and down-wide protection portion is additionally provided with the periphery at the top of the protection portion of the protective to be oriented to
Portion.More convenient another volume that readily enters in top that the guide part can guide shank of the present utility model is larger, again
Measure on positioning hole and its bottom surface or the top of larger, heavier-weight the part of another volume on relatively heavy component bottom
Positioning hole, and then cause positioning it is more convenient easily and efficiency it is higher.
Further, the protection portion guide part is that up-narrow and down-wide turbination is either polygon wedge-shaped or trapezoidal.This
So that relatively simple for structure, the manufacture of protection portion guide part are easier.
Further, the top of the protection portion of the protective is provided with the screw extended longitudinally downward.In such manner, it is possible to using
Screw element is connected with the screw and more convenient easily the protectives of repair and replacement will be needed to be taken out from the top of shank.
Further, the protective is integrally made up of softer elastic caoutchouc or elastoplast.This causes protective
Protecting effect preferably and be easier to fabricate.
Further, the protective is integrally made up of softer stretchy nylon or elastic polyurethane.This to protect
The protecting effect of body more preferably and is easier to fabricate.
