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 Mechanical measurement cylinder section, including bracket institution 3, connection member 2 and survey
Measuring mechanism 1, the bracket institution 3 and measuring mechanism 1 are mutually installed in cross structure by connection member 2 and fixed；The support
Mechanism 3 includes slide bar C 13, slide bar D 15 and the support 16 being set with successively from inside to outside, and the slide bar C 13 passes through fixture 12
On slide bar D 15 and it is located between one end inside slide bar D 15 and slide bar D 15 provided with spring B 14；It is described to survey
Measuring mechanism 1 includes connecting rod 8 and Central Symmetry is arranged on a pair of slide bar components of in the chute 9, both sides of spring A 7, the slide bar
Component includes the slide bar A 4 and slide bar B 5 of suit, and the slide bar A 4 is arranged on slide bar B 5 by connecting rod fastener 6, described
The one end of connecting rod 8 is fixed on the slide bar component of side, and the other end is provided with pulling needle 11, and being provided with the both sides of pulling needle 11 can horizontal orientation shifting
Dynamic mark block 10；The open slot 17 of the displacement of mark block 10 can be held by being provided with the chute 9 of the corresponding position of mark block 10.
The utility model is when making, and being provided with the surface of chute 9 of the correspondence position of open slot 17 is used to indicate two marks
