Abstract

A fixed measuring bar (2) and a measuring bar of a dial indicator (4) are located on the same straight line, the dial indicator (4) is corrected through a standard block before being used, and then is fixed through a fastening screw (3), the diameter of a water sealing groove of a cylinder sleeve can be measured through a pair of calipers, and the thickness can be directly detected through the dial indicator. When different boards with large thickness differences are detected, only the fixed measuring bar (2) needs to be replaced by different fixed measuring bars, or only the dial indicator (4) needs to be reinstalled at different positions, the dial indicator (4) is corrected again, and can be used, and certain universality is achieved. When boards with special structures are detected, and the measuring distance is long, a caliper body (1) can be replaced by different caliper bodies, and thus the detection purpose can be achieved.

Description

A kind of wall thickness and difference testing tool
Affiliated technical field
The present invention relates to a kind of accurate detecting method of special thickness.Be specially adapted to detect the detection method of thickness and thickness difference.
Background technology
At present, the accurate measurement of general thickness is except measurer slide calliper rule or milscale with general, use exactly special go-no go gauge clamp, owing to there being the singularity of some sheet material shapes, general measurer can not meet request for utilization completely, special clamp can only reflect matching degree qualitatively, the numerical value of can not quantitative response measuring, and special clamp does not have versatility.
Summary of the invention
The invention provides a kind of survey instrument and accurate measurement method of thickness, the reflection thickness that this method can not only be quantitative, and there is relative versatility.
It is, at the measuring point place of the logical not-go-end of common clamp, dial gauge is housed that the present invention solves technical method that its technical matters adopts, can use before use as long as first proofreaied and correct dial gauge with other various measurers such as master gauge schools.
The invention has the beneficial effects as follows, by the present invention, the thickness of sheet material that can not only be quantitative, also has very strong versatility.
Accompanying drawing explanation.
Below in conjunction with accompanying drawing, the present invention is further illustrated.
1. caliper bodies in figure, 2. fixing measuring staff, 3. holding screw, 4. dial gauge.
Embodiment
In figure, the measuring staff of fixing measuring staff (2) and dial gauge (4) is on same straight line, first with calibrated bolck, its dial gauge (4) is proofreaied and correct before use, then use holding screw (3) fixing, then can use these clamp to measure the sealing water channel footpath of cylinder jacket, can go out thickness by dial gauge direct-detection.When detecting the larger kind sheet material of thickness difference, only need to change different fixing measuring staffs (2) or reinstall the position of dial gauge (4), re-start correction, can use, there is certain versatility.For some special construction sheet material, when measuring position is far away, can exchange obstructed caliper body (1) for, can reach testing goal.Before measuring, according to the measurement of different range, with different calibrated length sample pieces, carry out verification, during measurement, according to the reading of demarcating sample piece and indicator, can measure concrete numerical value.The deviation of wall-thickness measurement can directly can be read wall thickness difference according to the hunting range of indicator.

Claims (2)

1. wall thickness and a difference testing tool, is characterized in that the measuring staff of fixing measuring staff (2) and dial gauge (4) is on same straight line, then uses holding screw (3) fixing.
2. a kind of wall thickness according to claim 1 and difference testing tool, its feature is first being proofreaied and correct its dial gauge (4) with calibrated bolck before use, and the hunting range that can go out thickness and indicator by dial gauge direct-detection is read Wall-Thickness Difference.
