Description
Technical field
The invention belongs to inspection jig technical field, is related to a kind of elastic taper pin positioning mechanism.
Background technology
, it is necessary to corresponding detent mechanism when being positioned with porose part.At present, alignment pin device to hole class zero is typically passed through
Part is positioned, and existing locating pin structure is simple, and the hole type parts of specific model can only be positioned, the scope of application compared with
It is narrow, and be difficult to position location and be difficult to determine.
The content of the invention
For the present invention in view of the above-mentioned problems, providing a kind of elastic taper pin positioning mechanism, the detent mechanism can eliminate positioning hole
Influence of the aperture in margin of tolerance inside dimension deviation is processed, repetitive positioning accuracy is high.
According to technical scheme：A kind of elastic taper pin positioning mechanism, it is characterised in that：Including pedestal, pedestal
Guide sleeve is fixed with endoporus, is slidably matched in guide sleeve endoporus and conical dowel pin is set, conical dowel pin one end is from guide sleeve
Middle stretching, conical dowel pin other end sheathed spring, spring one end are pressed on the step of conical dowel pin circumferential surface formation,
The spring other end is pressed in cover plate, and cover plate is anchored on the end face of guide sleeve, and the conical dowel pin circumferential surface is provided with first
Location division, circumference transition part and the second location division, moving range of the conical dowel pin in guide sleeve is by the spacing fixation of pin.
As a further improvement on the present invention, the guide sleeve is fastenedly connected by screw and pedestal.
As a further improvement on the present invention, first location division, the second location division are in coniform.
As a further improvement on the present invention, the conical dowel pin is provided with waist type groove, and pin is stretched into waist type groove will cone
Shape alignment pin is spacing to be fixed in guide sleeve.
The technical effects of the invention are that：This elastic taper pin positioning mechanism makes taper pin in positioning holes center by spring effect
Axis direction activity, the diameter in a certain section of taper pin is position location when identical with tested bore dia, is determined for measured workpiece
Position hole can be accurately positioned.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1, including conical dowel pin 1, the first location division 1-1, the second location division 1-2, circumference transition part 1-3, screw
2nd, guide sleeve 3, pin 4, spring 5, cover plate 6, pedestal 7 etc..
As shown in figure 1, the present invention is a kind of elastic taper pin positioning mechanism, including pedestal 7, it is fixed with the endoporus of pedestal 7
Guide sleeve 3, it is slidably matched in the endoporus of guide sleeve 3 and conical dowel pin 1 is set, the one end of conical dowel pin 1 is stretched out from guide sleeve 3,
The other end sheathed spring 5 of conical dowel pin 1, the one end of spring 5 are pressed on the step of the circumferential surface of conical dowel pin 1 formation, bullet
The other end of spring 5 is pressed in cover plate 6, and cover plate 6 is anchored on the end face of guide sleeve 3, and the circumferential surface of conical dowel pin 1 is provided with the
One location division 1-1, circumference transition part 1-3 and the second location division 1-2, moving range of the conical dowel pin 1 in guide sleeve 3
By 4 spacing fixation of pin.
Guide sleeve 3 is fastenedly connected by screw 2 and pedestal 7.
First location division 1-1, the second location division 1-2 are in coniform.
Conical dowel pin 1 is provided with waist type groove, and pin 4, which is stretched into waist type groove, is fixed on guide sleeve 3 by conical dowel pin 1 is spacing
In.
This elastic taper pin positioning mechanism makes taper pin a certain in the activity of positioning holes center axis direction, taper pin by spring effect
The diameter in section is position location when identical with tested bore dia, can be accurately positioned for measured workpiece positioning hole.
At work, conical dowel pin 1 stretches into and positioning operation is carried out in hole, the diameter in a certain section of conical dowel pin 1
When identical with tested bore dia, as position location, the extreme position that conical dowel pin 1 moves in the endoporus of guide sleeve 3 is by pin 4
Spacing fixation, when conical dowel pin 1 is in compressive state in guide sleeve 3, reset operation is carried out by spring 5.
