By it is shown in Fig. 4 containing the part of inclined hole to be measured for, to technical solution provided by the present invention carry out specifically
Bright: apolegamy matches the small measure-axis in gap with measured hole, and measure-axis is put into measured hole by sliding gauge block,
The angular position adjusting of rotational slide gauge block is fitted closely with tested hole surface, is improved hole and is measured the accuracy of surface intersection point,
Measure-axis and sliding gauge block that adjustment is worked good are tightened into fixation with Top fastening screw, the measuring tool is taken out and directly obtains hole depth ruler
It is very little.
In terms of inclined hole depth measurement, which obtains in multiple more than 100 procedures of 40 remainder part of emphasis model
Application has been arrived, inclined hole depth can accurately be measured.Operator can simple and convenient use, the accuracy rate of measurement is up to 100%.With
Assembling and setting is qualified for the part that this depth gage measuring is crossed, and fully meets properties of product requirement.Meanwhile shortening parts measurement
Time improves the efficiency of numerical control processing.In terms of manufacturing cost, it is widely applied in multiple emphasis models, by
Currently, can satisfy any angle inclined hole hole depth measurement, be not necessarily to design specialized depth gauge, since with the depth gauge measurement zero
After part, the time of measurer before shell is processed not only is shortened, the measurement period of part is also shortened, to be obviously improved
The processing efficiency of part.Meanwhile the measurement consistency of part is reliable, the Check-Out Time of part is obviously shortened, due to measurement zero
Scuffing caused by part significantly reduces.
By taking certain inclined hole of component hole measurement as an example, is measured compare with three kinds of methods respectively, it can be quasi- using the method for metering
True measures hole depth angle value, but due to the difference of bore dia and hole depth size, measuring head diameter and the selection of gauge head length are difficult,
One inclined hole just needs to choose a diameter with the gauge head being of convenient length and the suitable metering plug of cooperation measures, and measurement is all
Phase is long and cumbersome, and limitation is larger, poor universality；Between being easy to produce using calliper to measure since measuring rod shakes in hole
Gap and measurement club head cannot be contacted well with inclined hole end face completely, although so slide calliper rule directly measures the convenient measurement mistake of measurement
Difference is larger；Fit clearance can be not only eliminated by apolegamy plug with special depth rule, and the end face of plug is just and inclined hole
End face well contacts, this two o'clock is just eliminated with slide calliper rule drawback measured directly, by with the universal depth gage measuring mistake
Hole can accurately not only reflect depth value, and measurement facilitates simple and direct, and the accuracy and efficiency of measurement significantly improves.With ф 4
For hole, only need to design a set of depth measurer matched with 4 hole ф can accurately just measure all different angles of the part
4 hole depth size of ф, and it is simple and convenient.No matter from the storage and managenent for designing production cost or later period measurer of measurer
Apparent improvement is all obtained, which uses in the multiple parts in production scene, and part processing quality is more stable always, very
Meet production requirement well.
