Abstract

The utility model relates to a screw-thread depth measurer, consisting of a screw-thread plug gauge, a sleeve, a cylindrical pin, a plug gauge shaft, a measuring mandrel, a handle, a spring and a meter. The screw-thread plug gauge is inserted in one end of the plug gauge shaft and the other end of the plug gauge shaft is fixed in the handle. The measuring mandrel is mounted in an inner cavity of the plug gauge shaft in a slidable manner. One end of the measuring mandrel is connected with the sleeve by the cylindrical pin. The meter is mounted in the handle. A measuring head is supported on an end face of the other end of the measuring mandrel. The spring is sleeved on the measuring mandrel in the handle. The screw-thread depth measurer mainly solves a technology problem that conventional screw-thread plug gauges can't provide correct screw-thread depth sizes, breaks through conventional measuring methods, carries out screw-thread precision measurement and simultaneously achieves effective depth measurement of the screw thread. The measuring accuracy achieves 0.1 and a reading value achieves 0.01 (a dial-indicator display value).

Description

Depth of thread measuring appliance
Technical field
The utility model relates to the screw measurement device, particularly a kind of depth of thread measuring appliance.
Background technology
The degree of depth of screw thread has determined the stability that is threaded.The requirement of the part double thread degree of depth of aviation, automobile is very high.The measuring condition of the double thread degree of depth requires more and more higher for this reason.Simple measurement can not provide accurate measurement data.The quality requirements of the inapplicable high-precision product of its measuring method.
Traditional plug thread gauge can not provide the size of the correct depth of thread, in the field test and sampling observation of batch production, needs portable light cubing.Check fast, production status is adjusted.To darker aperture degree of depth check, do special measuring tool, therefore, very inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of depth of thread measuring appliance, it mainly solves the technical matters that traditional plug thread gauge can not provide the size of the correct depth of thread, it has broken through traditional measuring method, when double thread carries out precision measure, the measurement, the measuring accuracy that reach the double thread significant depth reach 0.1, reading value 0.01(dial gauge displayed value).
For achieving the above object, the utility model is to realize like this.
A kind of depth of thread measuring appliance is characterized in that: it is made of plug thread gauge, sleeve, straight pin, feeler gauge axle, measurement axle, handle, spring and gauging table; Wherein: this plug thread gauge is inserted on feeler gauge axle one end, and the feeler gauge axle other end is fixed in the handle; This measurement axle slidably is arranged in the inner chamber of feeler gauge axle, and the one end is connected with sleeve by straight pin; This gauging table is installed in the handle, and its gauge head withstands the other end end face of measuring axle; Be positioned on the measurement axle of handle and be arranged with a spring.
Described depth of thread measuring appliance is characterized in that: the described feeler gauge axle other end is fixed in the handle by holding screw.
Described depth of thread measuring appliance is characterized in that: described gauging table is installed in the handle by the flat-top screw.
Described depth of thread measuring appliance is characterized in that: described gauging table is dial gauge or clock gauge.
Technique effect of the present utility model and range of application are:
1, the utility model can be measured accuracy of thread and the degree of depth of internal thread simultaneously.
2, the utility model is high with the convenient identification of having of vernier graduation, precision with the digital display centimeter read-around ratio.
3, the utility model transposing gauge head can be measured the degree of depth that effective accuracy is carried out in any hole.
4, the utility model is simple and convenient, and the reliability of measurement is high.
5, the utility model is applicable to Site Detection.The large batch of screw thread of finding detects.
Description of drawings
Fig. 1 is surface structure synoptic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cut-open view.
Embodiment
See also Fig. 1,2, the utility model discloses a kind of depth of thread measuring appliance.As shown in the figure: it is made of plug thread gauge 1, sleeve 2, straight pin 3, feeler gauge axle 4, measurement axle 5, handle 7, spring 8 and gauging table 10.Wherein: this plug thread gauge 1 is inserted on feeler gauge axle 4 one ends, and feeler gauge axle 4 other ends are fixed in the handle 7; This measurement axle 5 slidably is arranged in the inner chamber of feeler gauge axle 4, and the one end is connected with sleeve 2 by straight pin 3; This gauging table 10 is installed in the handle 7, and its gauge head withstands the other end end face of measuring axle 5; Be positioned on the measurement axle 5 of handle 7 and be arranged with a spring 8.
In the utility model, described feeler gauge axle 4 other ends are fixed in the handle 7 by holding screw 6.
In the utility model, described gauging table 10 is installed in the handle 7 by flat-top screw 9.
In the utility model, described gauging table 10 is dial gauge or clock gauge.
When the utility model used, when rotary handle 7, plug thread gauge 1 screwed in the threaded hole gradually, measure sleeve 2 backward mobile drive measure axle 5 backward mobile touch gauging table 10(as: clock gauge) gauge head makes clock gauge show data.
Measuring principle of the present utility model is:
1, to be designed to the first complete tooth form be the accurately data that 0.5 pitch ± 0.05. has determined the depth of thread to the distance of end face in the end of plug thread gauge 1 of the present utility model.Common thread profile gauge does not have such standard code to provide inaccurate depth measurement.The dimensional accuracy of plug thread gauge is by national standard.
2, calibration is 0, measuring appliance vertically is placed on to make on the flat board measures sleeve end face and feeler gauge end face and coexist on the plane dial gauge inserted and make its gauge head touch measurement axle end face digital display digital to flash.Adjust rational position and fix dial gauge.Numeral is adjusted into 0.
The check screw thread, the distance that the measurement sleeve moves is that the numeral that digital dial gauge shows is exactly the degree of depth of screw thread.
3, plug thread gauge passes through, and with the no-go gage check, has finished the detection of double thread precision again.
Use main points of the present utility model:
1, the transposing of gauge head
The transposing gauge head is very easy, on feeler gauge, screws in feeler gauge with a nut with a gauge head jacket casing, and gauge head is extracted.
Installing only needs the gauge head shank is inserted in the hole of feeler gauge axle.Strike gently tightly with the rubber hammer.
2, measure the hole of deepening, need plug thread gauge and the calibration sleeve of customized lengthening.The installation calibrating zero-bit puts calibration sleeve and gets final product.
3, lose smart for the wearing and tearing that prevent thread profile gauge.Regularly double thread rule are done accuracy calibration.
The utility model depth of thread measuring appliance can be provided with 4 specifications (such as following table), is fit to the screw measurement of any pitch of M3-M20.
The above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
