Description
Technical field
It the utility model is related to measurement apparatus, more particularly to a kind of measurement dress that inclined hole depth can be measured in production scene
Put.
Background technology
With the high speed development of machinery industry, the pattern of machine components is also more and more, and incident difficulty is also more next
It is more prominent.Such as：Measurement for inclined hole depth, when running into the problem of tool wear needs tool changing, lathe or fixture to adjust, all need
After operator is wanted by measuring the size, then carry out the adjustment operation of related knife benefit, lathe or fixture.But due to not having
Special measurement apparatus, for these problems, therefore operator, be able to not can only be adopted by the gage measuring of the routine size
This size is measured with three coordinates and auxiliary stopper, and during three-dimensional coordinates measurement, stopper need to be suitably aided in diameter, if diameter is not
Properly, it is necessary to carry out three coordinate calculating.So, whenever changed cutter, adjustment lathe or fixture just need to send three coordinates
Detection, then, carry out three coordinate calculating.And now, to be measured, three coordinates the result of calculations such as operator can only just stop production,
Not only lose time, also reduce production efficiency；If not waiting measurement, result of calculation, directly produce, substandard product will be increased
The risk of outflow.
Utility model content
Main purpose of the present utility model is to overcome disadvantages mentioned above existing for prior art, and one kind is provided can be in life
The measurement apparatus of in-site measurement inclined hole depth is produced, it, can not only be at the scene after operating personnel's tool changing, lathe or fixture adjustment
The very first time oneself measures hole depth data, solves the problems, such as to send three coordinate measurements, calculates；Moreover, substantially increase production effect
Rate, reduce production cost.
The purpose of this utility model is realized by following technical scheme：
It is a kind of to measure the measurement apparatus of inclined hole depth in production scene, it is characterised in that：It is provided with：One can be put into by
Stopper in gaging hole, one end of the stopper are provided with a circular conical surface that angle is adapted with tested inclined hole, are tested on the top surface of inclined hole
Place a pair of table blocks.
The length L2 of the stopper is one section of length for arriving circular conical surface intersection point of stopper.
Height H=(L2- hole depths) * Cos of the table block are tested inclined hole and centre bore angle.
The beneficial effects of the utility model：The utility model is due to using above-mentioned technical proposal, its operating personnel at the scene
Tool changing, lathe or fixture adjustment after, can not only the very first time oneself measure hole depth data, solve send three coordinate measurements,
The problem of calculating；Moreover, the detection process only needs 0.5 minute, production efficiency is substantially increased, reduces production cost.

Embodiment
As shown in figure 1, the utility model is provided with：One can be put into the stopper 1 in measured hole, and one end of the stopper 1 is provided with
One is adapted the circular conical surface 2 of angle with tested inclined hole 3, and a pair of table blocks 4 are placed on the top surface of tested inclined hole 3.
The present embodiment：Tested inclined hole 3 and centre bore angle are 9 °, and therefore, the end face of stopper 1 makees one 9 ° of the conical surface.
The length L2 of above-mentioned stopper 1 is 1 one sections of length for arriving the intersection point of circular conical surface 2 of stopper.
Height H=(L2- hole depths) * Cos of above-mentioned table block 4 are tested inclined hole and centre bore angle.
To the size of table block 4：Table block 4 will be placed on the top surface A of tested inclined hole 3, calculated by trigonometric function, you can
To height H, H=(L2-33.4) the * Cos9 ° to table block 4.
During in-site measurement, it is only necessary to table block 4 will be placed on the top surface A of tested inclined hole 3, with platform, height gauge, dial gauge
(or amesdial) on to table block 4 to table after, then measure the circular conical surface 2 of stopper 1, pass through the beat amount of indicator, you can obtain by
The depth in deviational survey hole 3.
The angle of above-mentioned tested inclined hole 3 is ensured by lathe and fixture, and during normal process, its error can be ignored not
Meter, therefore only need to consider the variation of the tested axial direction of inclined hole 3.It is measurement on production line because tested inclined hole 3 is to prolong axis direction
The direction vertical with top surface A, it is therefore desirable to by measurement tolerance changed, calculated by trigonometric function, prolong axially bored line direction
Change 0.1, switchs to vertical top surface A direction changes 0.1*Cos9 °=0.099.Thus, we can be converted into 33.4 ± 0.2
H ± 0.19 is measured, so far, the problem of the depth in-site measurement of tested inclined hole 3 is resolved.
In use, stopper 1 is put into tested inclined hole 3, it is possible to which ensure circular conical surface always has a plain line and top surface A
Parallel, also, this plain line is in the peak of circular conical surface, such our can platforms, height gauge, dial gauge measures
This peak, now, as long as again coming table block 4 to table with what stopper 1 was of convenient length with one, we are measured by deviational survey can
The depth in hole 3.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, every any simple modification made according to the technical essence of the utility model to above example, equivalent variations with
Modification, in the range of still falling within technical solutions of the utility model.
