Description
Technical field
The utility model belongs to machining instruments of inspection technical field, and more particularly to a kind of tapped blind hole depth is quickly examined
Survey instrument.
Background technology
In the production of car engine mechanism member, the processing of required precision tapped blind hole higher, wherein screw thread are generally met
Blind hole depth mismachining tolerance must be controlled within ± 0.05mm, thus after machining, it is necessary to strict inspection is carried out, will
Defective work is rejected.The method of conventional blind depth inspection is generally using depth gauge rule or takes the straight-bar of equivalent substitution, this side
Method measures very inaccurate；The fixed length gauge rod patchhole that the use tool steel that mass producing the tapped blind hole inspection of enterprise has makes
It is interior, then the length that gauge block exposes blind hole is measured respectively with two special clamps, upper poor clamp and blind hole end face gapless and with amount
There is a gap on bar top, and lower poor clamp has gap and is certified products with gauge rod top gapless person with blind hole end face；If upper poor clamp
With gauge rod top gapless and have gap between blind hole end face, or lower poor clamp and blind hole end face gapless and with gauge rod top
It is defective work to have gap person.This mode is easily inclined due to clamp, thus its detection reliability is poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of tapped blind hole depth fast detecting tool, and this is quick
Whether detection instrument can more accurately, reliable check tapped blind hole working depth qualified and easy to use.
Realize that above-mentioned purpose is adopted the technical scheme that：A kind of fast fast detecting tool of tapped blind hole depth, including with
Gauge rod and the gauge block of cooperation is installed with gauge rod that tapped blind hole coordinates, the gauge rod top sets step, the height of the step
Less than or equal to the allowable tolerance of tested tapped blind hole depth.
Further, the gauge rod bottom sets the screw thread coordinated with tested tapped blind hole.
Further, the gauge rod is T-shaped structure.
Further, the gap between the gauge rod and the gauge block is 0.2 ~ 0.3mm.
Further, the gauge block via bottoms set chamfering.
Further, the gauge rod top sets anti-slip veins.
Further, the gauge rod and gauge block are tool steel or bearing steelwork.
Tapped blind hole depth fast detecting tool of the present utility model mainly has the advantage that：
1）The technical scheme that the instrument is coordinated with gauge rod and gauge block again, by way of vision or touch, can be accurate
Judge the whether qualified of examined workpiece, overcome the collimation error of prior art inspection；
2）The gauge rod bottom sets the screw thread coordinated with tested tapped blind hole, and gauge rod uses step shaft-like structure, the amount of making
Bar can easily screw in tapped blind hole, and can guarantee that gauge rod lower end is concordant with end thread, so that assay is more
It is accurate reliable；
3）Gap between the gauge rod and the gauge block is 0.2 ~ 0.3mm, installs the two and coordinates even closer, is passed through
When touching judgement, can prevent from producing erroneous judgement because of the two gap；
4）The gauge block via bottoms set chamfering, and anti-slip veins are set on gauge rod top, facilitate screwing and gauge block for gauge rod
With installing for gauge rod, check more convenient；
5）Gauge rod and gauge block are tool steel or bearing steelwork, and by quenched, quenching processing, can strengthen wearability
Can, overcome the two abrasion to cause to check error, increase the reliability of accurate inspection workpiece, and making for fast detecting tool can be extended
With the life-span, the need for adapting to the large quantities of a large amount of production testings of workpiece.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Referring to Fig. 1, tapped blind hole depth fast detecting tool of the present utility model, including gauge rod 1 and gauge block 2, gauge rod 1
Lower end can be inserted into the bottom of workpiece tapped blind hole 1-1 to be checked, and the gauge block 2 is cylinder or the prism bodily form, its upper and lower end face tool
There is the depth of parallelism higher, centre sets the through hole that cooperation is installed with the gauge rod 1.The top of the gauge rod 1 sets step, institute
The height h for stating step is less than or equal to the allowable tolerance of tested tapped blind hole 3-1 depth.As a further improvement, the amount
The bottom of bar 1 is threaded 1-1, can preferably coordinate with tested tapped blind hole, detects more accurate.Also gauge rod 1 can be made down
Screw thread position is held with diameter greater than the T-shaped structure of upper end light shank diameter, to shorten the length of screw thread position, precession tapped blind hole 3-1
Shi Gengjia is laborsaving.Gap between gauge rod 1 and gauge block 2 can not be too big or too small, it is preferably provided as 0.2 ~ 0.3mm, too big easy
Influence accuracy of detection, it is too small, it is difficult to install, influence detection efficiency.In order that gauge block 2 is to more quick when being installed on gauge rod 1,
Chamfering 2-1 should be set in the bottom of the through hole of the gauge block 2.In order that gauge rod 1 more facilitates in tapped blind hole 3-1 during precession,
The top of the gauge rod 1 can be set one section of anti-slip veins 1-2, be easy to it is hand-held screw, make detection more quick, but anti-slip veins position is most
Major diameter can not be more than the diameter of gauge rod 1.Used in large quantities of a large amount of productions, the gauge rod 1 and gauge block 2 all should use tool steel
Or bearing steel makes, and by quenched, quenching processing, to strengthen anti-wear performance, increase the reliability of accurate inspection workpiece, extension
The private life-span of fast detecting tool.
The gauge rod 1 when in use, can first be inserted or screw in tested tapped blind hole 3-1 and protect by the fast detecting tool
The lower end for demonstrate,proving gauge rod 1 reaches the bottom of tested tapped blind hole 3-1, and then gauge block 2 is installed on gauge rod 1, and under making gauge block 1
End face is adjacent to the upper surface of workpiece for measurement 3, now observes or touches the top of gauge rod 1 and the upper surface difference in height of gauge block 2 with finger
Different situation, if the upper surface of the upper end step of gauge rod 1 is not less than the upper surface of gauge block 2, and the step the lower surface amount of being not higher than
The upper surface of block 2 then illustrates that tested tapped blind hole processing is qualified；If the lower surface of the upper end step of gauge rod 1 is higher than the upper end of gauge block 2
Face, then illustrate that tested tapped blind hole 3-1 depth is less than projected depth, and the measured workpiece is reprocessed products, can by reprocess make by
The depth of seizure of the thread blind hole 3-1 reaches projected depth, is likely to become certified products；If the upper surface of the upper end step of gauge rod 1 is less than amount
The upper surface of block 2, then illustrate that the depth of tested tapped blind hole 3-1 has been more than projected depth, and the examined workpiece 3 is waste product.By
Only touch and can sentence easily and accurately with operator's vision or with hand when the tapped blind hole depth fast detecting tool is detected
Determine the quality condition of examined workpiece tapped blind hole processing, and detect easy to operate quick, thus can reliably ensure
Detection quality, and with detection efficiency higher, it is particularly well-suited to mass industrialized production.
Finally illustrate, above example is only used to illustrate the technical solution of the utility model and unrestricted, this area
Other modifications or equivalent that those of ordinary skill is made to the technical solution of the utility model, without departing from this practicality
The spirit and scope of new technique scheme, all should cover in the middle of scope of the presently claimed invention.
