Description

A kind of go-no go gauge for face inspection

Technical field

The utility model is related to gage measuring technical field, specially a kind of go-no go gauges for face inspection.

Background technology

Go-no go gauge is one kind of measurer, if large batch of product is taken with metering measurer (such as vernier calliper in actual production Ruler, the graduated measurer such as amesdial) very bothersome is measured one by one it is understood that qualified product is the there are one metrics range It is all qualified within the scope of this, so people just take drift end and no-go gage end to measure.Go-no go gauge is that two measurers are divided into Drift end and no-go gage end, go-no go gauge test bar on the market is all both ends formula structure now, i.e., one end is drift end, and the other end is No-go gage end, or be two-part structure.I.e. one section is drift end, and another section is no-go gage end, is needed not in face of different parts Stop replacing go-no go gauge.

But the prior art deposits the following deficiency：

1, the dismounting of traditional go-no go gauge is inconvenient, cannot replace required drift end and no-go gage end in time；

2, simple hole can only be detected, is had a single function.

Utility model content

(1) the technical issues of solving

In view of the deficiencies of the prior art, the utility model provides a kind of go-no go gauge for face inspection, solves inconvenience It dismantles and the problem of having a single function.

(2) technical solution

To achieve the above object, the utility model provides the following technical solutions：A kind of go-no go gauge for face inspection, including even Fitting, the connector outer surface is provided with non-slip mat, and connector upper end is provided with the first metallic rod, first metal Bar upper end is equipped with drift end, and drift end surfaces offer drift end screw thread, and the connector lower end is provided with the second metal Bar, and the second metallic rod lower end is equipped with no-go gage end, the no-go gage end surfaces offer no-go gage end screw thread, and the no-go gage end is placed In the hole of piece surface, the thread groove that first metallic rod is opened up with connector surface is mutually clamped, and thread groove It is fixed by bolt with the first metallic rod.

Preferably, the diameter at the no-go gage end and drift end is all higher than the second metallic rod and the first metal shank diameter.

Preferably, no-go gage end diameter is more than drift end diameter.

Preferably, the hole of the detection is circle.

Preferably, the thread groove of the connector tail end is mutually clamped with the embossed part on part noumenon surface

(3) advantageous effect

The utility model provides a kind of go-no go gauge for face inspection, has following advantageous effect：

(1) the utility model measures part by the way that drift end and no-go gage end is arranged, and utilizes drift end and no-go gage end Carry out measured hole whether within standard size tolerance, measure more standard, than very fast, suitable measure batch passes through measuring speed The thread groove of setting is mutually clamped with connector to be fixed using bolt, at the drift end for needing replacing different size and only When advising end, bolt is backed out into the drift end for i.e. detachably carrying out replacing different size and no-go gage end, logical stop need not be re-replaced Rule reduce use cost, and the non-slip mat of connector surface setting plays the role of increasing frictional force, which subtracts when in use Few hand strength.

(2) the utility model is threaded groove, the go-no go gauge device when in use, may require that sometimes to embossed part into Detection, connector and the first metallic rod are disassembled, and carrying out clamping with embossed part using spiral groove is detected, and increases The function of go-no go gauge reduces use cost and detection time.
