Abstract
The utility model discloses an utensil is examined to symmetry of fork axle blind hole, including bottom plate and positioner, the upper surface of bottom plate is equipped with and is used for placing the support of pitching the axle, and about the support symmetry is equipped with the percentage table that two levels set up, two the measuring staff of percentage table is perpendicular with the fork axle to outer peripheral face contact with the fork axle, positioner's lower extreme is equipped with the interior positioning head of blind hole that is used for injecting the fork axle. The utility model discloses, utilize two percentage tables about the support symmetry, insert the blind hole joint of fork axle at the positioning head and fix the back, can effectively reach the position error of both sides to judge the processing position error of blind hole, the step is simple, convenient operation, and the accuracy is high.
Description
Technical field
The utility model is related to mechanical cubing, and in particular to the symmetry degree gauge of fork shaft blind hole.
Background technology
Fork shaft is conventional mechanical part, and its is cylindrical to be typically machined with blind hole, therefore symmetry is not easy measurement, but symmetrically
Degree is the important parameter that it ensures normal work.At present metering system is relatively simple, can adopt universal gage measuring, but surveys
Amount speed is slow, and duplicate measurements has error, is easily damaged during use；Or annular groove is measured using kind of calliper hole two-end thickness
Depth, measure error is big；Or three-dimensional coordinates measurement is used, high cost, measurement is not convenient.
As can be seen here, current fork shaft survey tool has that measure error is big, unhandy.
Utility model content
Technical problem to be solved in the utility model be current fork shaft survey tool have that measure error is big, operation not
Just problem.
In order to solve above-mentioned technical problem, the technical scheme that the utility model is adopted there is provided a kind of fork shaft blind hole
Symmetry degree gauge, including：
Base plate, upper surface is provided with the bearing for placing fork shaft, and is arranged with two with regard to the bearing and is horizontally disposed with
Dial gauge, the measuring staff of dial gauge described in two is simultaneously vertical with fork shaft, and contacts with the outer peripheral face of fork shaft；
Positioner, lower end is provided with for the positioning head in the blind hole for injecting fork shaft.
In such scheme, the positioner include column, the fast fixture that is arranged on the column and by
The locating piece that the fast fixture drives, the positioning head is arranged on the lower end of the locating piece.
In such scheme, the positioning head is included for the cylindrical portion of positioning and the taper contacted with the blind hole on fork shaft
Portion.
In such scheme, the base is provided with two gauge stands, and the dial gauge is separately positioned on the gauge stand.
In such scheme, the surface of the dial gauge is upward.
In such scheme, the upper surface of the bearing is provided with the standing groove of V-arrangement.
In such scheme, the gauge stand is provided with heightens bolt.
The utility model, using two with regard to the symmetrical dial gauge of bearing, the blind hole clamping for inserting fork shaft in positioning head is consolidated
After fixed, the site error of both sides can be effectively drawn, so as to judge the Working position error of blind hole, step is simple, easy to operate, essence
Exactness is high.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structural representation of the present utility model.
Specific embodiment
The utility model is described in detail with reference to specific embodiment and Figure of description.
As depicted in figs. 1 and 2, the symmetry degree gauge of the fork shaft blind hole that the utility model is provided includes base plate 1 and positioning dress
Put.The upper surface of base plate 1 is provided with the bearing 11 for placing fork shaft, and is arranged with two horizontally disposed hundred with regard to bearing 11
Divide table 7, the measuring staff of two dial gauges 7 is vertical with fork shaft, and contacts with the outer peripheral face of fork shaft；The lower end of positioner is provided with for inserting
The positioning head 3 entered in the blind hole of fork shaft.
When being detected, two dial gauges 7 are calibrated first with verification part, then tested fork shaft is placed on into bearing 11
On, therewith positioning head 3 is inserted in the blind hole of fork shaft and connected and fixed, the reading of two dial gauges 7 is observed, obtain detection knot
Really.Whole detection process is easy to operate, and step is simple, can improve the accuracy of detection using two relative dial gauges, also more
Intuitively.
Preferably, positioner includes column 4, the fast fixture 6 being arranged on column 4 and by fast fixture
6 locating pieces 5 for driving, positioning head 3 is arranged on the lower end of locating piece 5.Moved using the control locating piece 5 of fast fixture 6, made
Obtain in the insertion blind hole of positioning head 3, it is simple to operate, save manpower.
Preferably, positioning head 3 is included for the cylindrical portion of positioning and the tapered portion contacted with the blind hole on fork shaft.Detection
When, location division is initially entered in blind hole, plays positioning and guide effect, and therewith tapered portion is entered, until connecing with the inwall of blind hole
Touch and fix, easily positioning and operation.
Preferably, base is provided with two gauge stands 2, and dial gauge 7 is separately positioned on gauge stand 2.The surface court of dial gauge 7
On.Amesdial is fixed using gauge stand, the fixing-stable degree of dial gauge 7 is improved, surface is more conducive to upward operating personnel's observation.
Preferably, the upper surface of bearing 11 is provided with the standing groove of V-arrangement, and the standing groove of V-arrangement can meet various various outer diameters
The placement of fork shaft, strong applicability.
Preferably, gauge stand 2 is provided with and heightens bolt, because two dial gauges 7 test the symmetry of blind hole, it is therefore necessary to etc.
Height, could accurately measure error amount.
The utility model, using two with regard to the symmetrical dial gauge of bearing, the blind hole clamping for inserting fork shaft in positioning head is consolidated
After fixed, the site error of both sides can be effectively drawn, so as to judge the Working position error of blind hole, step is simple, easy to operate, essence
Exactness is high.
The utility model is not limited to above-mentioned preferred forms, and anyone should be learnt under enlightenment of the present utility model
The structure change made, it is every that there is same or like technical scheme with the utility model, each fall within guarantor of the present utility model
Within the scope of shield.
