Description
Technical field
The utility model belongs to machining product field of measuring technique, and in particular to a kind of blind hole depth measuring tool.
Background technique
In blind hole depth measurement, generally using general measurer vernier caliper or production special measurement tool, both sides
Method can satisfy measurement demand, but there is also some practical difficulties.
1, it when using vernier caliper measurement blind hole depth, since drill head apical angle forms a conical surface in the bottom in hole, surveys
Gauge rod end face is difficult to find " bottom hole " accurately, usually finds the intersection on hole cylindrical surface Yu the bottom conical surface accurately by feel, and to measure repeatedly
It can determine that exact value.This measurement method working efficiency is low, and operator is needed to have certain working experience and technology water
It is flat.
2, special measuring tool measures.The design of special measuring tool is made using the depth dimensions tolerance in hole, in measuring tool
Up/down steps face is the upper and lower bound for indicating depth size, in measurement, by the way that step surface and datum level are touched or estimated with hand
Height determines whether part size is qualified.But in actual operation, depth size lesser for tolerance, according to said method production is special
With measuring tool, judging whether qualification, there are certain difficulties, because the step surface formed by the bound size of tolerance very little is not easy
Distinguish judgement.
Summary of the invention
The utility model mainly solves the problems, such as existing low efficiency or inaccuracy when the prior art measures blind hole, provides one
Kind blind hole depth measuring tool.
The utility model adopts the technical scheme that solve above-mentioned technical problem:
A kind of blind hole depth measuring tool, including dial gauge, gauge stand, its main feature is that: it further include connecting rod and triangular block, institute
Dial indicator measuring head is stated to be inserted into the gauge stand and be fixed by screws on gauge stand；The survey of described connecting rod one end and dial gauge
Head connection is measured, the other end is connected to triangular block, and the triangular block is affixed by the chuck and connecting rod of nut and connection boom end
Together；The triangular block cuts three arch for the disc shaped object of intermediate aperture and forms, and three arch form three after cutting
A edging；The bottom surface and side of the triangular block form right angle；
The connecting rod is Replacement Part, and length is depending on specific blind hole depth size；
The triangular block is Replacement Part, and diameter is depending on specific blind hole diameter size.
The utility model compared with prior art, has the advantages that
Since the triangular block that the utility model blind hole depth measuring tool uses can be replaced according to the size in hole, and
Triangular block reduces the contact area with inner hole, reduces friction convenient for measurement；The connecting rod of use can according to the depth in hole into
Row replacement, is adapted to the measurement of different blind holes, measurement effect is more intuitive, and detection efficiency is improved in this way.

Specific embodiment
As shown in Figure 1, a kind of blind hole depth measuring tool, including dial gauge 4, gauge stand 6, its main feature is that: it further include connection
Bar 1 and triangular block 3,4 measuring head of dial gauge are inserted into the gauge stand 6 and are fixed on gauge stand 6 by screw 5；The company
1 one end of extension bar is connect with the measuring head of dial gauge 4, and the other end is connected to triangular block 3, and the triangular block 3 passes through nut 2 and connection
The chuck of 1 end of bar is fixed together with connecting rod 1；As shown in Fig. 2, the roundel that the triangular block 3 is intermediate aperture is cut
Three arch form, and three arch form three edging 3-1 after cutting；As shown in figure 3, the bottom surface and side of the triangular block 3
Form right angle 3-2；
The connecting rod 1 is Replacement Part, and length is depending on specific blind hole depth size；
The triangular block 3 is Replacement Part, and diameter is depending on specific blind hole diameter size.
The utility model operating procedure:
When the utility model is used,
1, selected triangular block 3, connecting rod 1 are tightened by nut 3；
2, dial gauge and its associated part are connected；
3, dial gauge connecting rod mounting height is adjusted according to hole depth, guarantees lock-screw after indicator suitably pressure amount；
4, dial gauge dial plate is calibrated, is aligned pointer with zero graduation line；
5, part hole depth is measured, judges whether qualification.
