The measuring device includes connecting shaft 101, spherical bearing 102, the first measuring block 103, the second measuring block 104 and displacement
Sensor 105.
Wherein, the first measuring block 103 is for the first face contact to be measured with workpiece, and the first measuring block 103 is equipped with the
One mounting hole a.In figure, workpiece is concave workpiece 01, and the first tested surface of concave workpiece is higher-height in its two parallel surface
Face.It should be noted that workpiece is not limited to concave workpiece, for example it can also be convex workpiece or other tools there are two flat
The workpiece in row face.
Wherein, spherical bearing 102 is set in the lower end of connecting shaft 101 and is mounted in the first mounting hole a, specifically,
The inner ring and connecting shaft 101 of spherical bearing 102 are connected, and the outer ring of spherical bearing 102 and the first measuring block 103 are connected.Spherical axis
A certain amount of opposite swing can be generated by holding between 102 outer rings and inner ring, be that those skilled in the art are ripe in view of spherical bearing 102
The component known, its structure that details are not described herein.
Wherein, the second measuring block 104 can be connected in the first measuring block 103 up or down, and the second measuring block 104 is used for
With the second face contact to be measured of workpiece.In figure, the second tested surface of concave workpiece 01 is a lower height of face in its two parallel surface.
Also, the first contact workpiece of 104 to the first measuring block of the second measuring block 103, this specifically can be by according to workpiece shapes adjustment the
The height of the lower end surface of the height of the lower end surface of one measuring block 103 and the second measuring block 104 is realized, for example, when workpiece for measurement is
When the concave workpiece 01 of diagram, make the lower end surface of the second measuring block 104 lower than 103 lower end surface preset distance of the first measuring block
Make the first contact workpiece of the second measuring block 104.
Wherein, displacement sensor 105 is detection part well known to those skilled in the art comprising shell 1051 and from shell

1051 are connected with the second measuring block 104, in this way, when opposite first measuring block 103 of the second measuring block 104 moves up and down, detection
First 1052 also can be flexible with respect to shell 1051 therewith, so that the internal signal for triggering displacement sensor 105 changes, displacement is passed
The internal control unit of sensor 105 knows the displacement of detector 1052 according to the variation of internal signal.
Illustrate the measurement process of measuring device by taking Fig. 3 as an example:
Workpiece is located at the lower section of measuring device, and driving measuring device moves down, when moving down into certain altitude, the second measurement
Second face contact to be measured of block 104 and workpiece, under the conflict effect of workpiece, the second measuring block 104 is moved up, and makes the second survey
Relative displacement variation is generated between gauge block 104 and the first measuring block 103, correspondingly, being respectively connected to the displacement sensor 105 of the two
Shell 1051 and detector 1052 between also generate relative displacement variation, so that the registration of displacement sensor 105 be made to start to become
Change.
As measuring device continues to move down, the first face contact to be measured of the first measuring block 103 and workpiece, due to first
The right side of tested surface be higher than left side, so the right side stress of the first measuring block 103 be greater than left side, force the first measuring block 103 with
And each component being connected with the first measuring block 103 is (including the second measuring block 104, displacement sensor 105 and spherical bearing 102
Outer ring) it deflects to the left together, when the lower end surface for deflecting into the first measuring block 103 is overlapped with the first tested surface of workpiece, first is surveyed
The left and right sides stress of gauge block 103 reaches balance, no longer deflects.
When due to the deflection of the first measuring block 103, the second measuring block 104 also synchronous deflection therewith, so when the first measuring block
When 103 lower end surface is overlapped with the first tested surface, the lower end surface of the second measuring block 104 is also to be overlapped with the second tested surface, this
When, under the restriction effect of two coincidence faces, relative displacement is no longer generated between the second measuring block 104 and the first measuring block 103
Variation, correspondingly, being respectively connected to also no longer generate phase between the shell 1051 and detector 1052 of the displacement sensor 105 of the two
The registration of change in displacement, thus displacement sensor 105 is maintained in a stable registration, the stable registration and displacement sensor
The absolute value of the difference of 105 initial registration is the difference in height of two parallel surface of workpiece.
It should be noted that the initial registration of displacement sensor 105 can return to zero, and in the state of zeroing, displacement sensor
The absolute value of 105 aforementioned stable registration is the difference in height of two parallel surface of workpiece.
As above, which can be adaptively adjusted to the lower end surface of two measuring blocks and the tested surface of workpiece and coincide
State, so as to thoroughly eliminate since measurement caused by the lower end surface of measuring block and the tested surface of workpiece side are not parallel is inclined
Difference to improve the accuracy of measurement, also, eliminates the complicated procedures of forming for manually adjusting measuring device, to improve survey
