Abstract
The invention belongs to product testing fields, and in particular to the detecting tool and method of inclined hole hole back gauge on a kind of six square toes of bolt.Inclined hole hole back gauge on six square toes, slide calliper rule can not detect, and also without dedicated cubing, every batch of part operation quantity is more, bring very big difficulty to inspection work.The detecting tool of inclined hole hole back gauge on six square toes of bolt of the present invention, including mandrel and pedestal, the pedestal upper end band is fluted, groove relative to upper surface depth be inclined hole hole back gauge theoretical value；The mandrel and the inclined hole clearance fit.Using inclined hole hole back gauge in this detecting tool and detection method detection six square toes of bolt, reduce since the size is not easy to detect bring difficulty.And this detection method is simple and convenient to operate.
Description
Technical field
The invention belongs to product testing fields, and in particular on a kind of six square toes of bolt the detecting tool of inclined hole hole back gauge and
Method.
Background technique
Certain titanium alloy bolt design of part is short and small, referring to fig. 2, there is 3 inclined holes on its six square toes, i.e. aperture is distributed in phase
On adjacent side surface, the angle of adjacent inclined hole is 60 °, and aperture only has φ 1.5mm, and the width of six square toes is 10mm.Wherein six side
Inclined hole hole back gauge on head, i.e., inclined hole is at a distance from the apex angle of proximal end, it is ensured that minimum wall thickness (MINI W.) 0.7mm.When detecting the size, card
Ruler can not detect, and also without dedicated cubing, every batch of part operation quantity is more, bring very big difficulty to inspection work.
Summary of the invention
The technical problems to be solved by the present invention are: one auxiliary detecting tool of design and detection method, solve existing
Technology lacks the status of effective detection means to such inclined hole hole back gauge.
The detecting tool of inclined hole hole back gauge on six square toes of bolt of the present invention, for detecting inclined hole hole back gauge, i.e. on six square toes
Whether inclined hole is qualified at a distance from the apex angle of proximal end, which includes mandrel and pedestal, and the pedestal upper end band is fluted, and groove is opposite
Depth in upper surface is the theoretical value of inclined hole hole back gauge；The mandrel and the inclined hole clearance fit.
The diameter of the mandrel is less than inclined hole diameter 0.1mm.
The upper surface of the pedestal is horizontal.
The upper surface of the pedestal, which has, limits the constraint mechanism that the mandrel is planar displaced.
The pedestal and the material of mandrel are metal materials.
The pedestal and the material of mandrel are engineering plastics.
The surface roughness of the mandrel is less than 3.2.
The end point Edge Blend of the mandrel.
The method that inclined hole hole back gauge is detected on a kind of pair of six square toes of bolt, this process employs above-mentioned detecting tool,
And the following steps are included:
1, mandrel is passed through to the inclined hole on six square toes of bolt；
2, six square toes are put into the groove of pedestal, the both ends of mandrel are distributed on the upper surface of groove two sides；
3, hold down mandrel one end, if there are gap in the other end of mandrel and upper surface, and the gap is greater than the set value, it is believed that
It is unqualified, otherwise enter step；
If 4, the both ends of mandrel can stick on the upper surface of pedestal, whether the bar portion for detecting part is tilted, if inclination
Angle is greater than the set value, then it is assumed that and it is unqualified, it is otherwise qualified.
The utility model has the advantages that using this detecting tool and detection method detection six square toes of bolt on inclined hole hole back gauge, reduce by
It is not easy to detect bring difficulty in the size.And this detection method is simple and convenient to operate.
It can be substantially increased according to the mandrel and pedestal of inclined hole hole back gauge design plurality of specifications on different six square toes of bolt
Working efficiency.
Detailed description of the invention
Fig. 1 is the test schematic diagram of tooling of the present invention；
Fig. 2 is the structural schematic diagram of bolt part.
Wherein, 1- pedestal, 2- mandrel
Specific embodiment
The detecting tool of inclined hole hole back gauge on six square toes of bolt of the present invention, referring to Fig. 1, the aperture on six square toes of bolt is φ
1.5mm.The detecting tool includes mandrel 2 and pedestal 1, and mandrel diameters φ 1.4mm allows to oblique on six square toes of bolt
Hole.The pedestal 1 is character cut in bas-relief shape, and recessed depth is 0.7mm as the theoretical value of inclined hole hole back gauge on six square toes of bolt
Greatly.
When detection, mandrel 2 is passed through into inclined hole on six square toes of bolt, is then put into six square toes in the concave configuration of pedestal 1,
The both ends of mandrel 2 are distributed on the upper surface of concave configuration two sides of pedestal 1.Hold down mandrel 2 one end, if mandrel 2 is another
There are gap in one end and the upper surface of pedestal 1, and the gap is greater than 0.1mm, it is believed that product is unqualified, if otherwise the two of mandrel 2
End can stick on the upper surface of pedestal 1, and whether the bar portion for detecting part tilts, if tilt angle is greater than 0.5 °, then it is assumed that
Part is unqualified, otherwise qualified.
