Nut fixes pin connection, and one end that arm is measured on the graduated scale is provided with the first measurement point and the first measurement point and graduated scale
On zero graduation aligned in position, measure under the graduated scale to be connected on arm under graduated scale backing pin and graduated scale and measure the one of arm
End is provided with the second measurement point；
When edge line on the graduated scale towards graduated scale backing pin side is leaned against on graduated scale backing pin, the first measurement point with
The edge line of the line between line, first contact point and the second contact point, graduated scale between second measurement point is between any two
It is parallel to each other, and the distance between first contact point and the second contact point are equal between the first measurement point and the second measurement point
Distance.
Preferably, the first contact point and the second contact point are made of cemented carbide material.
Preferably, first locating plate and the second locating plate are circular configuration.
Preferably, when the edge line on the graduated scale towards graduated scale backing pin side is leaned against on graduated scale backing pin, first
The distance between measurement point and the first nut fixed pin are equal to the distance between first contact point and the first nut fixed pin.
Compared with prior art, the beneficial effects of the present invention are:
When measuring cast member wall thickness, it need to only rotate and measure arm under measurement arm and casting on casting, and make to measure arm on casting
On first contact point and casting under measure on arm the second contact point block the inside and outside table wall of cast member, then by graduated scale
Edge line leans against on graduated scale backing pin, and at this moment, survey crew can directly read the first measurement point on the scale and survey with second
The distance between amount point size, and then measure the wall thickness of cast member；During actual measurement can according to cast member itself
Structure situation determines to measure the shape for measuring arm under arm and casting on casting, will measure first on arm on casting to facilitate and connect
The inside and outside table wall that cast member is blocked in the second contact point on arm is measured under contact and casting, it is convenient, laborsaving that the present invention measures, and
And it does not need.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
Refering to Figure 1, a kind of cast member wall thickness special measurement device comprising measure on casting and surveyed under arm 1, casting
It is measured on amount arm 2, graduated scale and measures arm 4 under arm 3 and graduated scale, measured under arm 1 and graduated scale and measured between arm 3 on the casting
It is connected by the first locating plate 13, measures and measured on arm 2 and graduated scale between arm 3 through the second locating plate phase under the casting
