Description
Technical field
The utility model is related to a kind of measurer, especially a kind of new dial bore gage measurer.
Background technology
Electric automobile reduction case I, the hole size of II axle and wheelbase tolerance are high, and detection uses two in existing production process
Root measuring stick, insertion I, II axis hole simultaneously stretch out hole end surface, measuring stick span is then measured with micrometer, added by measured value or
Subtract two measuring stick real radius values, as holes center value.Detected using the above method, by measuring stick dimensional tolerance and shape
The influence of shape tolerance, adds the operating method and the technical capability of application micrometer of testing staff, can all influence measurement result, make
Larger into measurement cumulative errors, inefficiency, testing cost is high.
Utility model content
To solve the technical problem in above-mentioned background technology, the utility model provides a kind of new dial bore gage amount
Tool, described dial bore gage measurer can realize reduction case holes wheelbase and two axially bored lines in the wheelbase direction depth of parallelism
Detection, measuring method is simple, efficient, precision is high, cost is low.
Specifically, new dial bore gage measurer described in the utility model, includes dial gauge 1, adjusting screw 2, table
Frame 3 and activity measurement head 6, it is characterised in that also with U-shaped measurement support 4 and fixation measuring first 5；Increase U-shaped measurement on dial framework
Support 4, U-shaped measurement support 4 one end is fixed on the activity measurement head 6 of dial bore gage, and internal diameter percentage is fixedly installed in the other end
The fixation measuring first 5 of table.In measurement, the position that two measurement end three is resized to communicate, using outside micrometer or
The special sizing gauge of person, is corrected to internal diameter lever meter face end size, rotates percentage dial plate, makes reading to " 0 ", after correction
Fixation measuring head locking nut is tightened, you can measure and calculate, it is achieved thereby that measuring the simple and high purpose of precision.
In the present embodiment, U-shaped measurement support 4 is fixedly connected by screw and clamp nut with activity measurement head 6, is passed through
Locking nut is fixedly connected with fixation measuring first 5, and stability between each part of the measurer is improved with this, improves the survey of the measurer
Accuracy of measurement.
In the present embodiment, it is to be detachably fixed between U-shaped measurement support 4 and activity measurement head 6 and fixation measuring first 5
Connection.By being removably fixedly connected with mode, the length of U-shaped measurement support and inner size can be different according to different casings
Aperture and centre-to-centre spacing size carry out Series Design, thus expand the scope of application of measurer described in the utility model.

Embodiment
With reference to embodiments and the technical solution of the utility model is described in detail respective drawings, so that this area
Technical staff can be more clearly understood from scheme of the present utility model, but and be not so limited protection model of the present utility model
Enclose.
The utility model provides a kind of new dial bore gage measurer, and described dial bore gage measurer, which can be realized, to be subtracted
Fast device casing holes wheelbase and two axially bored lines in the detection of the wheelbase direction depth of parallelism, measuring method is simple, efficiently, precision it is high, into
This is low.Specifically, new dial bore gage measurer described in the utility model, includes dial gauge 1, adjusting screw 2, dial framework 3
And activity measurement head 6, it is characterised in that also with U-shaped measurement support 4 and fixation measuring first 5；Increase U-shaped measurement branch on dial framework
Frame 4, U types measurement support 4 one end is fixed on the activity measurement head 6 of dial bore gage, and dial bore gage is fixedly installed in the other end
Fixation measuring first 5.In measurement, the position that two measurement end three is resized to communicate, using outside micrometer or
Special sizing gauge, is corrected to internal diameter lever meter face end size, rotates percentage dial plate, makes reading to " 0 ", is twisted after correction
Measurement head locking nut is fastened, you can measure and calculate, it is achieved thereby that measuring the simple and high purpose of precision.
In the present embodiment, U-shaped measurement support 4 is fixedly connected by screw and clamp nut with activity measurement head 6, is passed through
Locking nut is fixedly connected with fixation measuring first 5, and stability between each part of the measurer is improved with this, improves the survey of the measurer
Accuracy of measurement.
In the present embodiment, it is to be detachably fixed between U-shaped measurement support 4 and activity measurement head 6 and fixation measuring first 5
Connection.By being removably fixedly connected with mode, the length of U-shaped measurement support and inner size can be different according to different casings
Aperture and centre-to-centre spacing size carry out Series Design, thus expand the scope of application of measurer described in the utility model.
In the exemplary embodiment illustrated in fig. 2, according to the theoretical pitch-row of casing holes, the principal radii of holes is added, selection is closed
Suitable support is carried out after installation calibrating, is rotated percentage dial plate, is made reading to " 0 ", is measured and is recorded illustrated dimensions L surveys, uses respectively
The dial bore gage of standard specification measures the actual diameter D1 and D2 of holes, calculates：
L pitch-rows=L survey-(D1+D2)/2
In the embodiment shown in fig. 3, according to method shown in Fig. 2, meter calculates the rear and front end wheelbase of holes respectively,
That is in Fig. 3 before dimensioning L and after L, by can be calculated on wheelbase direction, the depth of parallelism (δ ∥) of two axially bored lines：δ//=│
LBefore-LAfterwards│。
It the above is only and preferred embodiment of the present utility model is described, not by technical side of the present utility model
Case limited to this, any known deformation that those skilled in the art are made on the basis of major technique of the present utility model design
The claimed technology category of the utility model is belonged to, the specific protection domain of the utility model is with the record of claims
