Description
Technical field
The utility model relates to dimension detection tool technical fields, and in particular to a kind of taper hole dimension measuring device.
Background technique
Currently, when measurement has the taper of the workpiece of taper hole, the taper plug gauge for being A with identical taper i, groove standard value
Taper hole is filled in, feeler gauge standard groove and product taper hole large end face distance k is measured with Steel Ruler, by calculating, it is big to obtain taper hole
It holds size m (m=A-k × i)；When needing to measure small end size, can only be obtained by measuring product taper hole length j by calculating
Obtain small end size n (n=m-j × i).Above-mentioned detection mode workload is cumbersome, and the product of different pore size needs to change corresponding specification
Feeler gauge, working efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of taper hole dimension measuring devices, to solve the existing workpiece with taper hole
When measuring taper, the cumbersome problem of workload.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of taper hole dimension measuring device, comprising: pedestal, taper body and scale；The lateral surface of taper body is tapered, cone
Degree is consistent with the taper of the taper hole of workpiece for measurement, and taper body is set on the base, and the lateral surface of taper body is set along its axis direction
There is resettlement groove, the lateral surface of taper body is additionally provided with the reference reticle of the axis of vertical flare body；Scale is set in resettlement groove, mark
The extending direction of ruler is parallel with the axis direction of taper body, the graduation mark alignment fiducials groove of scale.
The taper body of the utility model is covered at the top of taper body to bottom for being arranged workpiece for measurement, workpiece for measurement
If being bonded until between workpiece for measurement and taper body.The reference reticle of the external side of taper is corresponding with a datum diameter.Scale is set
It sets in resettlement groove, being bonded for workpiece for measurement and taper body will not be hindered.When workpiece for measurement and taper, which are shown consideration for, to be closed, pass through mark
Ruler can directly read the corresponding scale value of reference reticle and workpiece for measurement taper hole big end and the corresponding scale value of taper hole small end.
If reference graduation is in the small end of taper body, taper hole small end size=datum diameter+(taper hole small end corresponds to scale value-reference reticle
Corresponding scale value) × taper, taper hole big end size=datum diameter+(taper hole big end corresponds to scale value-reference reticle corresponding quarter
Angle value) × taper；If reference graduation, in the big end of taper body, (taper hole small end is corresponding to be carved taper hole small end size=datum diameter-
Angle value-reference reticle corresponds to scale value) × taper, taper hole big end size=(taper hole big end corresponds to scale value-to datum diameter-
Reference reticle corresponds to scale value) × taper.By intuitively reading corresponding scale value on scale, carrying out simple calculate is
Can get taper hole small end size or taper hole big end size, do not need be additionally carried out measurement, avoid occurring when manual measurement compared with
Big deviation.In addition, increasing the length of taper body, identical taper, but the detection of the product of different pore size can satisfy.
Further, the big end of above-mentioned taper body is connect with pedestal, and the small end of taper body is far from pedestal.
Further, said reference groove is set to the small end of taper body.
Further, said reference groove is set to the big end of taper body.
The small end in taper body can be set in the reference reticle of the utility model, and the big end in taper body also can be set,
Only taper hole small end size is different with the calculation of taper hole big end size at this time, but corresponding scale value can be straight from scale
It reads out with seeing.
Further, the zero graduation line of said scale is aligned with reference reticle.
The zero graduation line of the utility model scale is aligned with reference reticle, is conducive to quickly read corresponding scale value, and
And it can simplify calculating process.If reference graduation is in the small end of taper body, taper hole small end size=datum diameter+taper hole small end pair
Scale value × taper is answered, taper hole big end size=datum diameter+taper hole big end corresponds to scale value × taper；If reference graduation is being bored
The big end of body is spent, taper hole small end size=datum diameter-taper hole small end corresponds to scale value × taper, taper hole big end size=base
Collimation diameter-taper hole big end corresponds to scale value × taper.
Further, the bottom surface of above-mentioned resettlement groove is parallel with the axis of taper body, and the bottom surface of scale and resettlement groove is adjacent to.
After the bottom surface of the utility model resettlement groove is parallel with the axis of taper body, convenient for the installation of scale, in installation scale
When do not need extraly to proofread the depth of parallelism.
Further, said scale is connected by the bottom of screw and resettlement groove.
Further, said scale extends along direction equipped with strip-shaped hole, and screw passes through strip-shaped hole and connect with taper body.
Strip-shaped hole on the utility model scale mobile scale in the case where screw position can be made motionless, enables scale
It is finely tuned in extending direction, its graduation mark is made to be more easily aligned reference reticle.
The utility model has the following beneficial effects:
Scale is arranged on taper body in the utility model, by intuitively reading corresponding scale value on scale, carries out
Simple calculate can be obtained taper hole small end size or taper hole big end size, does not need be additionally carried out measurement, avoid artificial
Occurs biggish deviation when measurement.In addition, increasing the length of taper body, identical taper, but the product of different pore size can satisfy
Detection.
