Abstract
The invention relates to the technical field of length alignment and relates to a point contact type thickness measuring device comprising a steel base (1), a cylindrical column (3) fixed to the base (1), an indicator stand (6) movable on the cylindrical column (3) freely and parallel to the base (1), a dial indicator (4) movable up and down on the indicator stand (6), and an R measuring head (7) fixed to the base. The indicator stand (6) and the cylindrical column (3) are fastened by means of fastening screws (2), the dial indicator (4) and the indicator stand (6) are fastened by means of fastening screws (5), the R measuring head (7) is perpendicular to the head of the dial indicator (4), and the point contact thickness of a test piece is measured by the R measuring head (7) and the dial indicator (4). The point contact type thickness measuring device of the invention adopts point-to-point measurement, with no shape error. Therefore, the requirement for the flatness of the test piece is not high and the measurement efficiency is greatly improved.
Description
Technical field
The invention belongs to lengthy calibration technical field, it is related to a kind of point contact type measurer for thickness.
Background technology
Before invention, the thickness measurement device of the part of each type is generally three-dimensional coordinates measurement, vertical comparator measurement, outside micrometer
Measurement, there is problems with them：
1 many part requirements measurement thickness are point-to-point thickness, and three coordinates or vertical comparator measurement thickness be all with
On the basis of one plane, with a gauge head measurement, i.e. point-to-area thickness, thus the form error of plane is brought into and be coming, survey
Amount resultant error is big, inaccurate.
Although 2 can reduce the impact of form error with outside micrometer measurement, when running into heavy parts, outside micrometer is surveyed
Amount less than.
3 some large-sized sheet material part such as composites need to have measured the thickness of multiple spot, carry out ultrasonic analysis, use existing equipment
I.e. slow, precision is unsatisfactory for requiring again.
4, in the case of material deformation, cannot accurately measure the thickness of part with above-mentioned measuring apparatus.
Content of the invention
The technical problem to be solved in the present invention：
A kind of new, convenient, practical point contact type measurer for thickness is provided.Thus meeting drawing or the point of technical specification is right
The thickness requirement of point.
Technical scheme：
A kind of point contact type measurer for thickness, including steel base 1, the cylindrical column 3 that is fixed on base 1, can justify
The dial framework 6 parallel to base 1 moving freely on cylindricality column 3, the dial gauge 4 that can move up and down on dial framework 6, solid
It is scheduled on the R gauge head 7 on base, fastened by trip bolt 2 between described dial framework 6 and cylindrical column 3, described dial gauge
Fastened by trip bolt 5 between 4 and dial framework 6, described R gauge head 7 and dial gauge 4 gauge outfit vertical relative, by R
Gauge head 7 and dial gauge 4 gauge outfit carry out to test block contacting thickness measure.
Beneficial effects of the present invention：
The point contact type measurer for thickness structure of the present invention is simple, easy to operate, has a safety feature, maintenance cost is low.This
The point contact type measurer for thickness of invention is point-to-point measurement, there is not form error, so will to the flatness of measured piece
Ask not high, simple to operate, measurement efficiency greatly improves.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below the present invention is described in further details.Referring to Fig. 1, point contact type measurer for thickness, its structure composition：
It can be moved freely for 3, one by 1, cylindrical column being fixed on base of a steel base on cylindrical column
6, two trip bolts 2 and 5 of dial framework parallel to base, the 7, dial gauge 4 of R gauge head being fixed on base
Composition.
The operation principle of the present invention is：
According to the suitable dial gauge of accuracy selection of measured piece, precision is higher, selects amesdial,
Otherwise select dial gauge.
Can be with dial gauge to zero and then direct measurement in the case of measured piece thickness is less.Quilt
In the case that survey part thickness is larger, then can measure again with gauge block to zero.
During measurement, it is contained on dial framework according to the suitable dial gauge of accuracy selection first, unclamp the position that trip bolt 2 adjusts dial framework
Put the gauge head making dial gauge 4 and the R gauge head 7 being fixed on base
Point-blank, tighten screw 2.Unclamp trip bolt 5, the upper-lower position of adjustment dial gauge 4 be fixed on bottom
R gauge head 7 contact on seat makes the pointer of dial gauge 4 press half-turn, tightens screw 5, repeatedly lifts the measuring staff of dial gauge 4,
To zero, at this moment just can measure.
During measurement, the measuring staff of lifting dial gauge is placed on part between table and gauge head and all around looks for point minimum of a value to be repeatedly survey
Amount result.
