Specific embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this hair
It is bright to be further detailed.
With reference to shown in Fig. 2-6, the invention provides a kind of measuring method of clamp seal groove, seal groove includes the first side wall
201st, second sidewall 203, and the second bottom wall that the first bottom wall 202 connected with the first side wall 201 connects with second sidewall 203
204, the first side wall 201 is relative with second sidewall 203, and the first bottom wall 202 connects with the second bottom wall 204, existing in order to solve
Defect present in technology, the present invention is made that following technological improvement：The measuring method is comprised the following steps：At clamp 100
In the first measurement position, and definition datum face 300, the first profile of the bottom wall 202 of the first side wall 201 and first is measured and drawn
Line；Clamp 100 are in the second measurement position, the second contour line of the bottom wall 204 of second sidewall 203 and second is measured and draw；
On the basis of datum level 300, first round profile is merged with the second contour line to form the complete contour curve of seal groove, and measure
The distance between the bottom wall 202 of datum level 300 and first, second bottom wall 204.Using this technical scheme, clamp are individually positioned in
Different measurement positions, in two measurement positions, draws the first round profile and the second contour line of seal groove, then with benchmark respectively
On the basis of face, two contour lines are merged into the contour curve of complete seal groove, improve in the prior art using three coordinates or
The defect that projecting apparatus cannot be measured, and realize the accurate detection to seal groove.
Measurement to the inwall of seal groove, can be measured, yet with it using the probe 11 for being installed on contourgraph 10
Tip is relatively sharp, and easily measured surface is caused to scratch, and in order to overcome this defect, contourgraph preferably uses Zaser contourgraph,
Zaser contourgraph uses laser scanner technique, with high-frequency, high accuracy, can accurately and quickly be measured, and connect for non-
Measurement is touched, the inwall of seal groove will not be caused to damage, compared to contact measurement, its performance is more preferably.
Contourgraph 10 measures rear, it is necessary to be with datum level 300 by first round profile and the second contour line to seal groove
Benchmark is merged so as to obtain final measurement result, in order to improve the degree of accuracy of data processing, in the present embodiment, preferably
First round profile and the second contour line are merged by being connected to the computer of Zaser contourgraph, by computer disposal and are surveyed
Amount result, in this scheme, the contour line for obtaining is measured twice to be needed to be merged according to same datum level to be allowed to form complete
The contour curve of seal groove, computer compares embedded single-chip microcomputer, and its data-handling capacity is stronger, and the degree of accuracy is higher.
And further, in order to improve the degree of accuracy of the measuring method, also including clamp 100 are in into different measurement positions
When measuring table 20, specifically, the fixed plate 21 of measuring table 20 including horizontal positioned, and the support in fixed plate 20
Plate 22, supporting plate 22 includes the first plate 221, and is in the second plate 222 of predetermined angle, the first measurement position shape with the first plate 221
Into fitting in the first plate 221 and fixed plate 21, the second measurement position is formed at fitting for the second plate 222 and fixed plate 21, this
In scheme, when being changed to the second measurement position from the first measurement position, only need to be with the intersecting of the first plate 221 and the second plate 222
Line is axle center turning-over support plate, and without mobile inlay card, it is ensured that the accuracy of measurement result.
In order to ensure that clamp 100 are reliably fixed in supporting plate 22, preferably supporting plate 22 is provided with multiple location-plates 223,
From clamp 100 against to limit its displacement for being located at different measurement positions, specifically, location-plate 223 sets each location-plate 223 respectively
Put on the first plate 221 and the second plate 222, when clamp 100 are in different measurement positions, different location-plates 223 and clamp
100 against to limit the free degree of its motion, certainly, the difference of the measurement position that location-plate 223 can also be according at clamp
Selection is installed, will location-plate 223 be set to removable attachment structure, it is easy to use, and positioning is reliable.Certainly, can also lead to
Cross viscose glue clamp are bonded on the supporting plate to limit its movement, the scheme of fixed caliper is not limited only to this, the present invention to this not
Limit.
The above is only the preferred embodiment of the present invention, it should be pointed out that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention, and, after present disclosure has been read, relevant technical staff in the field can be with
Various changes or modification are made to the present invention, these equivalent form of values equally fall into the model that the application appended claims are limited
Enclose.
