Description
Technical field
It the utility model is related to connecting rod appearance profile degree cubing.
Background technology
The detection of current outline degree is typically all instrumentation, such as profile tolerance instrument, can detect exact numerical, but instrument price is high
It is high, and need operator to possess the operative skill of specialty, cumbersome, detection time is grown, and is not suitable for batch detection.
Utility model content
Technical problem to be solved in the utility model is generally speaking to provide a kind of connecting rod appearance profile degree cubing；In detail
The technical problem and acquirement beneficial effect of solution content in aftermentioned content and combination embodiment specifically describe.
To solve the above problems, technical solution adopted in the utility model is：
A kind of connecting rod appearance profile degree cubing, including bottom plate, be arranged on bottom plate and for inserting in crank pin end pore
Major part alignment pin, the spring base installed in bottom plate lower end and below major part alignment pin, it is arranged on major part alignment pin and spring
Spring between seat, it is arranged on bottom plate and for contacting the V-block on positioning linkage rod microcephaly top, the gear positioned at V-block both sides
Block, the vertical block positioned at V-block afterbody, the spring being arranged between V-block and vertical block and it is arranged on bottom plate lower end and its lower end
Face and the contour supporting plate in spring base lower surface；
V-block slides setting between the block of both sides, is additionally provided with bottom plate for detecting big end profile wheel
The inspection block of wide degree.
Further improvement as above-mentioned technical proposal：
Also include the gauge for being used for gap between detection design exterior feature degree model curved surface and big end appearance profile degree to be measured,
Gauge includes lever, and maximal clearance detection block and minimum clearance detection block are respectively arranged with the lower end of lever.
Maximal clearance detection block is located at the top of minimum clearance detection block, and drift is additionally provided with lever.
The design exterior feature degree model curved surface for examining block is designed by drawing big end appearance profile degree.
The larger parts of tolerance are required for profile tolerance（Except special-shaped facial contour）, such as connecting rod forging fractal area profile tolerance
It is required that generally without departing from the+0.3mm of theoretical appearance profile, this requirement is to avoid connecting rod from occurring when operating with other parts
Interference.Connecting rod forging needs batch detection, and profile tolerance requires less high, is not suitable for using profile tolerance instrument in this case,
For this, we devise a kind of special gauge, do not detect exact numerical, and a judgement is qualified just as drift, no-go gage or does not conform to
Lattice, easy to operate, cheap, detection（Differentiate）Accurately, quick detection can be realized, is adapted to batch detection.
The special profile tolerance cubing of connecting rod is by connecting rod positioner and demarcation profile reference block（Examine block）Composition, positioner are adopted
With big end hole and microcephaly's excircle orientation, as can be seen that macropore alignment pin can be stretched up and down using compression spring in sectional view, by top
Portion's circular conical surface positioning centering big end hole.As can be seen that cylindrical floated using V-block stage clip or so of microcephaly is positioned in front view, V-type
Block is combined guided by block and vertical block, its shaft is in horizontality.Inspection block is fastened by alignment pin bolt, ensures its mark
Fixed wheel exterior feature molded breadth, and each normal section width are consistent namely equidistant, setting width=master bar diameter（As directly
Footpath is 6mm alloy bar）+ profile tolerance tolerance（Such as 0.3mm）.Small end of connecting rod is placed at V-block during detection, then pressing and to
Microcephaly direction is slided, and macropore is justified with the alignment pin conical surface and is completely attached to, and is then taken advantage of a situation with master bar manual from demarcation profile passageway
Streak, can pass through as qualified, it was demonstrated that profile tolerance meets forging requirement tolerance；It can not pass through, be judged to not conforming to
Lattice, it was demonstrated that profile tolerance is overproof.
The beneficial effects of the utility model not limited to this describes, in order to preferably readily appreciate, in embodiment portion
Divide and carried out more detailed description.

Embodiment
As shown in Figure 1-2, the connecting rod appearance profile degree cubing of the present embodiment, including bottom plate 1, be arranged on bottom plate 1 and use
In the major part alignment pin 2 in insertion crank pin end pore, installed in the lower end of bottom plate 1 and positioned at the spring base of the lower section of major part alignment pin 2
8th, the spring between major part alignment pin 2 and spring base 8 is arranged on, is arranged on bottom plate 1 and for contacting the small crown of positioning linkage rod
The V-block 4 at end, the block 6 positioned at the both sides of V-block 4, the vertical block 5 positioned at the afterbody of V-block 4, be arranged on V-block 4 and vertical block 5 it
Between spring and be arranged on the lower end of bottom plate 1 and its lower surface and the contour supporting plate 7 in the lower surface of spring base 8；
V-block 4 slides setting between the block 6 of both sides, is additionally provided with bottom plate 1 for detecting big end profile
The inspection block 3 of profile tolerance.
The connecting rod appearance profile degree cubing of the present embodiment, in addition to for detection design exterior feature degree model curved surface 14 and company to be measured
The gauge 9 in gap between bar major part appearance profile degree, gauge 9 include lever 11, maximum are respectively arranged with the lower end of lever 11
Gap detection block 12 and minimum clearance detection block 13.
Maximal clearance detection block 12 is located at the top of minimum clearance detection block 13, and drift 10 is additionally provided with lever 11.
The design exterior feature degree model curved surface 14 for examining block 3 is designed by drawing big end appearance profile degree.
During using the utility model, the small overhead of reconditioning and overlap and burr in big end hole, major part alignment pin 2 is inserted
In big end hole, pass through the Auxiliary support of V-block 4, self-centering setting, by measuring big end appearance profile with designing wide degree model
Curved surface spacing, to judge profile tolerance, in order to further facilitate measurement, by holding gauge 9, by above-mentioned spacing respectively between maximum
Gap detection block 12 or minimum clearance detection block 13 compare, when more than maximal clearance detection block 12, it was demonstrated that big end hole is eccentric serious, by force
Degree is inadequate；When less than minimum clearance detection block 13, it was demonstrated that seriously gear hinders big end hole lateral wall；Then it is marked by drift 10.
The utility model is designed reasonably, cost are cheap, durable, safe and reliable, simple to operate, time saving and energy saving, saving
