Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not construed as limiting the claims.
Referring to Fig. 1 to Fig. 5, the embodiment of the invention provides a kind of cubing knuckle cubing, including pedestal 100,
Left support abutment 200, right support abutment 300, left measuring block 400, right measuring block 500 and slide bar 600；Wherein, it is provided with and is used on pedestal 100
The gap 110 of knuckle 800 is installed, and the position set on pedestal 100 is fixedly installed amesdial 700；200 He of left support abutment
Right support abutment 300 is fixed on pedestal 100, and left support abutment 200 and right support abutment 300 are symmetrically dispersed in the two of gap 110
Side；Be provided with through slot 210 on left support abutment 200 and right support abutment 300, through slot 210 include two parallel vertical slots 211 and one with
The translot 212 of two vertical slots 211 connection；The first through hole of the measuring staff for wearing amesdial 700 is provided on right support abutment 300；
Left measuring block 400 is fixedly connected with left support abutment 200, and right measuring block 500 is fixedly connected with right support abutment 300, and left measuring block 400 with
Right measuring block 500 is symmetricly set on the two sides of gap 110, and the distance between left measuring block 400 and right measuring block 500 are less than and turn
To the diameter of the axle journal 810 of section 800；One end of slide bar 600 is fixed on left measuring block 400, the other end of slide bar 600 with
Measuring staff contact.
In 810 size of axle journal of utilization knuckle cubing provided in an embodiment of the present invention measurement knuckle 800, can incite somebody to action
Knuckle 800 is pushed into from the opening of gap 110 to the bottom direction of gap 110, when knuckle 800 is pushed to gap 110
When bottom, the axle journal 810 of knuckle 800 can be contacted with the left measuring block 400 of 110 two sides of gap and right measuring block 500 simultaneously, and
Apply the thrust on separate 110 direction of gap respectively to left measuring block 400 and right measuring block 500, due to left support abutment 200 and the right side
Through slot 210 is offered on support 300, therefore the edge separated on left support abutment 200 and right support abutment 300 by through slot 210 can be by left survey
The drive of gauge block 400 and right measuring block 500 and flexible deformation occurs to the direction far from gap 110 respectively, and then with moving slide-bar
600 move in the opposite direction with side lever, contact since the end of slide bar 600 is remained with side lever, therefore can make amesdial
The variation that numerical value occurs on 700, it is possible thereby to directly read the diameter dimension of axle journal 810；Specifically, referring to Fig. 5, through slot 210
Left support abutment 200 is divided into marginal portion 250 and middle section 260, the thickness of marginal portion 250 is smaller, and elasticity easily occurs and becomes
Shape, and the thickness of middle section 260 is thicker, therefore do not deform in 200 loading process of left support abutment, it follows that in left survey
When gauge block 400 is by active force to the left, marginal portion 250 can by left measuring block 400 drive and be moved to the left, make close to cunning
The width of the vertical slot 211 of bar 600 by marginal portion 250 extruding and become smaller, and far from slide bar 600 vertical slot 211 width
Then become larger, so that slide bar 600 be made to be moved by the drive of marginal portion 250, amesdial 700 is made to generate the variation of numerical value, realized
