Embodiment
With reference to embodiment and compare accompanying drawing the utility model is described in further detail.It should be emphasized that
It is, what the description below was merely exemplary, rather than in order to limit the scope of the utility model and its application.
The cubing of a kind of cylinder block cylinder holes seam end face run-out degree and flatness, including support shaft 3, guiding short column 4, amount
Tool, dial framework 2, it is oriented to short column 4 and is incorporated in the lower end of support shaft 3, in addition to taper datum plate 1, dial framework 2 is incorporated in the upper end of support shaft 3；
Taper datum plate 1 is incorporated in the top of support shaft 3 and between dial framework 2 and guiding short column 4.Measurer is amesdial and is assemblied in dial framework
2 right-hand members, the amesdial gauge head point to the cylinder-bore seam plane and can be with the seam plane contacts.It is oriented to the diameter of short column 4
It is essentially identical with cylinder holes diameter under measured cylinder block.The upper surface of taper datum plate 1 is level reference, utilizes the reference plane
Auxiliary dial framework is coordinated to measure the flatness of seam facet again；The upper surface diameter of taper datum plate 1 is more than its lower surface, is easy to
Measurement.
In preferred embodiment, in addition to spirit level 5, the upper surface of taper datum plate 1 open up a horizontal deep gouge；Spirit level 5
It is assemblied in horizontal deep gouge.Spirit level 5 is embedded on taper datum plate 1, ensures that the bubble of spirit level 5 is rested among graduation mark
During position, the upper surface of taper datum plate 1 is in horizontality, now also should ensure that upper surface and the support of taper datum plate 1
The central axis upright of axle 3.
Further, support shaft 3 is multi-diameter shaft, and the multi-diameter shaft is divided into axle I31, main shaft 32, axle II33, cone from the bottom to top
Axle 34；Guiding short column 4 is middle part hollow cylinder；Taper datum plate 1 is middle part hollow round table；Dial framework 2 is swing rod, and its left part is opened
Provided with the taper hole to match with the axis of cone 34, right-hand member offers the positioning hole 23 of assembling amesdial, and the inwall of positioning hole 23 is equipped with out
Mouth copper sheathing 21, amesdial sleeve, which is placed in opening copper sheathing 21 and withstands the pretension thousand of opening copper sheathing 21 with clamping screw 22, to be divided
Table.Purpose using opening copper sheathing 21 is to avoid clamping screw 22 from being directly expressed to amesdial sleeve to cause to deform, amesdial
Damage.Taper hole is with the axis of cone 34 by the way that to attrition process, guarantee is good fit, can guarantee that dial framework 2 is not altered up and down in rotation process
Move, do not swing.Taper datum plate 1 is truncated cone-shaped structure, reduces the contact area of the side of taper datum plate 1 and cylinder holes, is advantageous to
The level correction of taper datum plate 1；The upper surface diameter of taper datum plate 1 is bigger 1mm than cylinder block upper cylinder half bore dia, and lower surface is straight
Footpath is smaller 3mm than upper cylinder half bore dia.
Further, for axle I31 with being oriented to the centre bore interference fits of short column 4, axle I31 lower ends open up screw, and use flange face
Bolt 41 is directed to short column 4 and is locked on axle I31；Axle II32 and taper datum plate 1 centre bore interference fits, main shaft 32 are set
There is ear shoulder, flange face bolt 11 is through the ear shoulder and screws in taper datum plate 1, is locked.It is oriented to short column 4, taper datum plate
1st, the three's central coaxial of support shaft 3.
Further, taper datum plate 1 cuts out flat position 12 in the axial direction, and guiding is short, and 4 have also cut similar and taper benchmark
The flat position of plate 1.
Further, in addition to handle 6, handle 6 are incorporated in the upper surface of support shaft 3.
Further, dial framework 2 is stepped, left-thick right-thin, it is therefore an objective to which the center of gravity of dial framework 2 is in left end, left end design and branch
Frame axle 3.
This cubing application method：
1) measurement verification is carried out to cubing before using, meets to use during design requirement；
2) when implementing measurement, burr, burr are removed into tested position, then this cubing is placed in measured cylinder holes, is filled
Upper amesdial, cubing is adjusted, when the bubble of spirit level 5 is rested among graduation mark, now the upper surface of taper datum plate 1 is in
The axis of horizontality and support shaft 3 overlaps with the central axis of cylinder holes, can be to carry out the end face to cylinder holes seam facet
Beating degree measures, and dial framework 2 turns around around the axis of cone 34 of support shaft 3, you can measures the end face run-out degree of cylinder holes seam facet；
3) subsequently using auxiliary gauge stand and amesdial, auxiliary gauge stand bottom is close to the upper surface of taper datum plate 1, and thousand
Divide table gauge head to be contacted with seam facet, amesdial zeroing, seam flatness, mobile auxiliary are measured in correct position uniform stationing
Gauge stand makes amesdial gauge head prolong moving radially for the sensing axis of support shaft 3 in the width range of seam facet, you can measurement
Data, then cubing is turn 90 degrees again, again the upper surface of the taper datum plate 1 of level-off cubing, measured with same method
Flatness, finally by data processing, obtain the flatness of seam facet.
It would be recognized by those skilled in the art that it is possible that numerous accommodations are made to above description, so embodiment and attached
Figure is intended merely to describe one or more particular implementations.
It is counted as example embodiment of the present utility model although having been described above and describing, those skilled in the art will be bright
