Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
The device of maximum inner diameter difference on a kind of electronic type measuring cylinder body section, including the measurement mutually installed in cross structure
Mechanism 1 and bracket institution 3, high accuracy displacement sensor 2 is provided with the intersection of measuring mechanism 1 and bracket institution 3, described high-precision
Degree displacement transducer 2 passes through the external handheld terminal 4 of data cable 5；The measuring mechanism 1 includes chute 15, inside chute 15
Center is fixed with spring A 14, slide bar component is arranged with spring A 14 two ends, the slide bar component is by slide bar A
Slide bar B 13 is set with outside 11 by slide bar fastener 12 to constitute；The bracket institution 3 includes the cunning being set with successively from inside to outside
Bar C 31, slide bar D 34 and support 35, the slide bar C 31 are arranged on inside slide bar D 34 by fixture 32, its end and cunning
Spring B 33 is provided between bar D 34；The slide bar C 31 and slide bar D 34 are marked with the quarter for determining the spread length of support 35
Degree.
During measurement, the central point in cylinder section is first determined with bracket institution 3, measuring machine is then adjusted according to the diameter of cylinder
The slide bar A 11 at the two ends of structure 1 makes length meet the requirements, and tightens slide bar fastener 12, then rotation measuring part, and slide bar A 11 exists
It is brought into close contact in the presence of spring A 14 with cylinder inboard wall, in rotation process, due to cylinder not circular ideal, so two can be made
The slide bar B 13 at end produces corresponding displacement difference.High accuracy displacement sensor 2 is produced accordingly by the slide bar B 13 at two ends
Displacement difference detection data.The displacement differences of slide bar B 13 at two ends cause resistance-type or condenser type high accuracy displacement sensor 2
Potential change, current potential is converted into after data signal, just turns into the internal diameter data of collection.Internal diameter data are inputted by data cable 5
To handheld terminal 4, handheld terminal 4 possesses storage and computing function, automatic after test ending to calculate measured internal diameter data most
Greatly with the difference of minimum value and being shown on the display screen of handheld terminal 4.Once having more than standard value, handheld terminal 4 will be certainly
Dynamic alarm.
Embodiment：
Exemplified by measuring internal diameter for 2000mm pressure vessel, the central point in cylinder section is first determined with bracket institution 3, will
