Description
Technical field
The utility model belongs to inspection jig technical field, is related to a kind of elastic V-block detent mechanism.
Background technology
When positioning boss, need to use corresponding detent mechanism.Existing detent mechanism in use,
Coarse localization can only be carried out to boss, it is difficult to realize the reliable assurance to position location.In addition, existing positioning device can only be real
Now to the positioning of specific standard boss, the active homing of positioning convex platform is difficult to realize in position fixing process.
Invention content
For the utility model in view of the above-mentioned problems, providing a kind of elastic V-block detent mechanism, which can eliminate positioning
Boss is in the influence of margin of tolerance inside dimension deviation, repetitive positioning accuracy height.
According to the technical solution of the utility model：A kind of elasticity V-block detent mechanism, it is characterised in that：Including being installed on
Guide holder in positioning pedestal endoporus slides setting V-type locating piece in guide holder endoporus, and V-type locating piece is equipped with annular projection,
Spring is equipped between annular projection and the counterbore step of guide holder, the spring upper end is held out against on annular projection, and lower end compresses
In on counterbore step, V-type locating piece lower end is stretched out from guide holder, and catch, gear are fixedly installed in the lower face of V-type locating piece
The outer diameter of piece is more than guide holder endoporus lower end diameter；The V-type locating piece upper end is equipped with V-groove, and the notch upper end of V-groove is equipped with
Chamfering, and the upper end notch of V-groove is big, lower end notch is small.
As further improvement of the utility model, the guide holder is fixedly connected by bolt with positioning pedestal.
As further improvement of the utility model, the catch is fastenedly connected by screw on V-type locating piece.
The utility model has technical effect that：The utility model elasticity V-block detent mechanism makes V-type by spring effect
Block is in positioning convex platform central axial direction activity, as positioning when the size in a certain section of V-block is identical with positioning convex platform size
Position can be accurately positioned.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1 ~ 3, including V-type locating piece 1, annular projection 1-1, V-groove 1-2, guide holder 2, counterbore step 2-1, spring
3rd, catch 4, screw 5, positioning pedestal 6 etc..
As shown in Fig. 1 ~ 3, the utility model is a kind of elastic V-block detent mechanism, including being installed on 6 endoporus of positioning pedestal
In guide holder 2, setting V-type locating piece 1 is slided in 2 endoporus of guide holder, V-type locating piece 1 is equipped with annular projection 1-1, cyclic annular
Spring 3 is equipped between raised 1-1 and the counterbore step 2-1 of guide holder 2,3 upper end of spring is held out against on annular projection 1-1,
Lower end is pressed on counterbore step 2-1, and 1 lower end of V-type locating piece is stretched out from guide holder 2, and in the lower face of V-type locating piece 1
Catch 4 is fixedly installed, the outer diameter of catch 4 is more than 2 endoporus lower end diameter of guide holder；1 upper end of V-type locating piece is equipped with V-groove
The notch upper end of 1-2, V-groove 1-2 are equipped with chamfering, and the upper end notch of V-groove 1-2 is big, lower end notch is small.
Guide holder 2 is fixedly connected by bolt with positioning pedestal 6.
Catch 4 is fastenedly connected by screw 5 on V-type locating piece 1.
Catch 4 in the utility model product is it is possible to prevente effectively from V-type locating piece 1 is skidded off from guide holder 2；To boss
When carrying out positioning operation, the notch in V-groove 1-2 realizes the positioning to boss.The lower end notch of V-groove 1-2 is equipped with circular groove.
During positioning operation, 1 downward compressed spring 3 of V-type locating piece, at the end of positioning operation, V-type locating piece 1 under the action of spring 3,
Carry out reset operation.
The utility model product makes V-type locating piece 1 in positioning convex platform central axial direction activity, V-type by the effect of spring 3
As position location when the size in 1 a certain section of locating piece is identical with positioning convex platform size, can be accurately positioned.
