[background technology]
5J30T front and rear housings reverse gear hole is not a complete hole, and only have 2/5 part in whole hole, the precision comparison in this hole is high, and tolerance only has 0.1mm.Add man-hour at the scene, due to the factor such as wearing and tearing of cutter, the size in uncontrollable aperture, each workpiece will be detected, and measuring amount is large, but this incomplete hole cannot use conventional feeler gauge or R rule to carry out Survey control, be measured by three-dimensional at present, but three-dimensional coordinates measurement have the following disadvantages: in order to the accuracy measured, multiple point on hole wall will be adopted, add the time of measurement, the requirement detected fast cannot be met.
Whether change according in comparison procedure, relative method can be divided into " direct comparison method " and " indirect relative method " two classes.
One, direct comparison method: the simplest direct comparison method is exactly the standard volume with measurer belonging to similar physical quantity to be measured directly compared, and measures its size.Such as measure length with meter ruler, by stopwatch Measuring Time etc.
Two, indirect relative method: be compared by measured parameter and certain standard volume (calibrating device), thus draw the deviate of measured parameter relative to standard volume.Because standard volume is known, therefore, the whole value of measured parameter equals the simple algebraic sum of deviate and standard volume.Like this, as long as standard volume is fixed, then can judge that whether the value of measured parameter is suitable.
[utility model content]
The purpose of this utility model is to overcome problems of the prior art, provides a kind of and measures the high Quick detecting checking tool of efficiency.
In order to achieve the above object, the utility model adopts following technical scheme:
Comprise the clock gauge containing zero setting structure, measuring staff and gauge head, and contain the check gauge of go side half bore and not-go-end half bore, wherein, the lower limit that check gauge go side half bore dia is qualified with workpiece for measurement diameter is equal, and the upper limit that not-go-end half bore dia is qualified with workpiece for measurement diameter is equal; The measuring staff of clock gauge is fixed with locating piece, and the gauge head in measuring staff extend out to outside locating piece, in the go side half bore that the end that locating piece contains gauge head can snap in check gauge and not-go-end half bore, and now the end of gauge head can contact with go side half bore and not-go-end half bore.
Further, locating piece connecting bottom board, base plate is clipped in clock gauge circumferentially.
Further, locating piece is T-shaped, and T-shaped two shoulders are connected with base plate respectively by fillister head screw.
Further, the end that locating piece contains gauge head is provided with circular arc chamfering, and this arc diameter is less than or equal to the diameter of go side half bore.
Further, table cover is provided with between locating piece and measuring staff.
Further, locating piece by with the perpendicular flush end holding screw fixed cover of measuring staff on measuring staff.
Compared with prior art, the utility model has following useful technique effect:
The utility model is by arranging check gauge, containing go side half bore and not-go-end half bore on it, and qualified with the workpiece for measurement diameter respectively bound of the diameter of go side half bore and not-go-end half bore is equal respectively, thus half bore on this check gauge is equal with the limit deviation of workpiece for measurement, returned to zero by the go side half bore on clock gauge and check gauge, record the change numerical value of clock gauge in check gauge not-go-end half bore again, the margin tolerance of workpiece for measurement can be indicated, compare with workpiece again, determine workpiece aperture size whether in margin tolerance, judge that whether workpiece is qualified easily, measure fast and easy, efficiency is high.
Further, the utility model, by arranging base plate, makes the connection of locating piece and clock gauge more firm, prevents both relative slidings from making measurement produce error.
Further, the utility model, by arranging circular arc chamfering, effectively reduces the wearing and tearing to locating piece end in measuring process, makes measurement more accurate.
Further, the utility model, by arranging table cover, can fix clock gauge better.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further details.
See Fig. 1 to Fig. 3, the utility model comprises the clock gauge 2 containing zero setting structure, measuring staff and gauge head, and contain the check gauge 6 of go side half bore and not-go-end half bore, wherein, check gauge 6 go side half bore dia is equal with the lower limit of workpiece for measurement diameter qualified institute permissible variation, and not-go-end half bore dia is equal with the upper limit of workpiece for measurement diameter qualified institute permissible variation; From inside to outside sheathed table cover 5 and T-shaped locating piece 3 successively on the measuring staff of clock gauge, run through locating piece 3 by the flush end holding screw 4 perpendicular with measuring staff and show cover 5, then end connects with measuring staff, three is fixed; And the gauge head in measuring staff extend out to outside the T-shaped leg of locating piece 3, the T-shaped leg end of locating piece 3 is provided with circular arc chamfering, this arc diameter is less than or equal to the diameter of go side half bore, ensure in the go side half bore that its end can snap in check gauge 6 and not-go-end half bore, and after locating piece 3 snaps in, the end of gauge head can contact with go side half bore and not-go-end half bore; T-shaped two shoulders of locating piece 3 are respectively by fillister head screw 7 connecting bottom board 1, and base plate 1 is clipped in clock gauge 2 circumferentially.
Specific works process of the present utility model and principle: the utility model is by comparing with check gauge 6, thus whether the processing dimension of measuring workpieces meets drawing requirement indirectly, first clock gauge 2 is measured in the go side half bore of check gauge 6 during use, and returned to zero by the zero setting structure of clock gauge 2, then the clock gauge 2 after using zeroing is measured in the not-go-end half bore of check gauge 6, and record change numerical value, again the hole on workpiece is measured, if the numerical value of clock gauge 2 is in this numerical value during measuring workpieces, then think that workpiece size is suitable.
Concrete analysis: because the dimensional tolerence of workpiece only has 0.1mm, just the collapsing length of gauge outfit in 0.1mm margin tolerance can be simulated under environment painted by Inventor grass, as shown in Figure 4: when from figure, we can draw the value x=16mm as chord length AB, diameter is in ultimate value
with
between when changing, the stroke of corresponding gauge outfit is respectively y1=3.45mm and y2=3.428mm, then stroke change only has 0.022mm (3.45-3.428), so determine to select clock gauge 2, makes measuring accuracy high.
The utility model Application comparison mensuration principle, by the standard gauge block of clock gauge 2 and workpiece size limit deviation to zero, then compares with workpiece, determines workpiece aperture size whether in margin tolerance, thus controls the machine workpieces at scene.
