The side of platform 2, for measuring the narrow groove inside pipe fitting 9 to be measured.
Mobile station 5 is installed on sensor displacement mechanism 6, extending bracket 4, mobile station 5 and extension are installed in mobile station 5
Support 4 is vertically arranged with sensor displacement mechanism 6, and a total reflection prism 3 is provided with the end of extending bracket 4, is being extended
The position that the end of support 4 is located at the lower section of total reflection prism 3 is provided with a printing opacity aperture 10, is set in the upper surface of mobile station 5
There is laser displacement sensor 7.Extending bracket 4 stretches into the inside of pipe fitting 9 to be measured, when laser beam is axially injected along tested pipe fitting
When, total reflection prism reflection light makes it irradiate straight down, through printing opacity aperture 10；
The sensor displacement mechanism 6 can move up and down along the radial direction of pipe fitting 9.
The grating scale is arranged in the X-direction of XY mobile platforms and the slide plate of Y-direction.
Axis of the laser beam that the extending bracket and the laser displacement sensor are launched all with tested pipe fitting
It is parallel,
As shown in Fig. 2 the pipe fitting 9 is tested pipe fitting, the laser displacement sensor 7 is installed with the extending bracket 4
In the mobile station 5 of the sensor displacement mechanism 6, the extending bracket 4 carries the total reflection prism 3 and stretches into the pipe fitting
In 2.The laser beam 8 is launched by the laser displacement sensor 7 along pipe fitting axial direction.The total reflection prism 3 is anti-
Penetrating the laser beam 8 makes it be irradiated in inside pipe wall straight down.The mobile station 5 is arranged on the sensor displacement mechanism 6
On, it can be moved up and down along the radial direction of the pipe fitting 2.The V-block 1 is fixed on the XY mobile platforms 2.The XY movements are flat
