Description
Technical field
This utility model relates to a kind of quickly detection female thread and rotates aid, it is adaptable to quickly spiral shell in detection blind screwhole
Stricture of vagina mating pitch diameoter and effective depth, belong to the technical field of thread measurement instrument.
Background technology
Threaded is one of modal connected mode in machine-building, because it connects reliable, simple in construction, manufacturer
Just widely used.Regular screw threads standard GB/T T197-2003 internal threads define two kinds of basic deviations of G, H and 3～9
The level grade of tolerance, selects according to requirements for designer.In actual application, some crucial and important parts are carried out even
Connecing, its blind screwhole not only internal threads precision has strict demand (such as 6G, 7H etc.), and the distance between screwed hole is also had tolerance
Requirement.Such as, at space industry, structural member is required for through various performance tests after assembling, and structural member processes through surface
After, its surface has one layer of coating, plays and prevents structural member surface Oxidation, but this process frequently can lead to qualified spiral shell
Pit becomes defective, because structural member inner-cavity structure is complex and has the screwed hole of various different size, this is accomplished by
Screwed hole is detected more accurately.
Conventional screwed hole detection instrument is plug thread gauge, and its two is cone shape, but plug thread gauge itself has
Certain limitation, existing plug thread gauge has the disadvantage in that
The first, when detecting the effective thread degree of depth of screwed hole, the cone of plug thread gauge first contacts with bottom screwed hole, leads
Cause cannot detect the effective thread degree of depth of screwed hole.
The second, it is fixing due to the reach of plug thread gauge, causes cannot directly detecting the screwed hole that inner chamber is deeper,
And when detection is near the screwed hole of structural member sidewall, it is difficult to operation.
3rd, the screwed hole of many different size is distributed on conventional structural member, when detection, only relies on finger and rotate
Plug thread gauge detects, and the detection cycle is longer, also can cause finger fatigue or damage.
As can be seen here, need badly design a kind of can quick and precisely, general easily measure screwed hole female thread instrument.
Utility model content

The wire that cone handle tilts.
The cross sectional shape of pull bar uses triangle or rectangle.
The two ends of pull bar are equipped with the adhesive plaster for fixed pulling rope.
Stay cord is wrapped on screwdriver handle along single direction.
The quantity of stay cord is no less than 2, and the material of stay cord uses nylon.
Screwdriver handle, crewdriver attachment, screw and sleeve pipe are all coaxial and can dismantle flexibly, the size of crewdriver attachment, screw and sleeve pipe
Can arrange the most flexibly.
This utility model compared with prior art provides the benefit that:
1, this utility model is by crewdriver attachment, screw and the cooperation of sleeve pipe, it is achieved that the effective thread degree of depth to screwed hole
Detect, overcome traditional plug thread gauge and cannot detect a difficult problem for the effective thread degree of depth.
2, this utility model coordinating by pull bar and screwdriver handle, it is achieved that in complex environment, screwed hole is carried out
Detection, solves the problem that traditional plug thread gauge cannot directly detect the screwed hole of the deeper and close structural member sidewall of inner chamber.
3, this utility model coordinating by stay cord and wire, reached the effect of quick measurement screwed hole, shortened five
The detection time of/tri-, improve detection efficiency, compensate for traditional plug thread gauge detection cycle longer defect.
4, screw of the present utility model and sleeve pipe can be arranged the most flexibly, brief and practical, compared to traditional
Plug thread gauge, has adaptable feature.
5, pull bar of the present utility model is mutually perpendicular to the laminating of screwdriver handle and axis, meets the design of human engineering,
Effectively slow down the fatigue strength of staff and improve the stability that instrument is overall.
6, pull bar of the present utility model is provided with the opening for installing stay cord, has highly versatile, applied widely
Feature, significantly reduces production cost.
7, screwdriver handle of the present utility model, turncap, crewdriver attachment, stay cord, wire, adhesive plaster, screw and sleeve pipe are mark
Quasi-part, it is not necessary to special, maintainability is strong, it is easy to install.
