Embodiment
An embodiment of securing member foreign side of the present invention rapid detection tool is as shown in Fig. 3 ~ Fig. 6, be a kind of detection frock for detecting aviation fasteners hexagon head bolt 8, this hexagon head bolt 8 comprises the foreign side 11 that bar portion 9, head 10 and the outer peripheral face by head 10 are formed.Detect frock and comprise the frock main body 1 being provided with foreign side's draw-in groove 2, frock main body 1 is axially through annular solid, and its center has axially extending bore, and axially extending bore forms foreign side's draw-in groove 2.This axially extending bore is that shape is identical with the shape of the foreign side 11 of detected hexagon head bolt 8, and be sexangle, good looking appearance, is convenient to the location of hexagon head bolt 8.
Foreign side's draw-in groove 2 has two and is parallel to each other and the detection side wall surface 3 arranged in opposite directions, this detection side wall surface 3 has for the front and back bearing of trend consistent with the direction of insertion of hexagon head bolt 8, this bearing of trend is axial consistent with frock main body 1, and during use, the head 10 of hexagon head bolt 8 inserts from the front end of frock main body 1.Detection side wall surface 3 described in two is arranged symmetrically and is ledge structure, and the spacing of ledge structure leading portion is comparatively large and equal with the upper limit of the opposite side size of the foreign side 11 of hexagon head bolt 8, forms upper limit measuring section 4; After ledge structure, certain distance is less and equal with the lower limit of the opposite side size of the foreign side 11 of hexagon head bolt 8, forms lower limit measuring section 5.The spacing of all the other two groups of side wall surfaces of foreign side's draw-in groove 2 is greater than the upper limit of the opposite side size of securing member foreign side 11 to be measured, can avoid causing interference to all the other opposite side of foreign side 11 on hexagon head bolt 8.
For the ease of the insertion of hexagon head bolt 8, the front end surface of frock main body 1 being provided with chamfering 6 structure in the notch edges place of foreign side's draw-in groove 2, for guiding securing member foreign side 11 to enter in foreign side's draw-in groove 2, being conducive to improving detection efficiency.For the ease of testing staff's operation, the outer peripheral face of frock main body 1 is provided with anti-skidding annular knurl 7, avoids occurring skidding.
When using above-mentioned detection frock to detect hexagon head bolt 8, first the detection side wall surface of foreign side's draw-in groove 2 is corresponding with wherein one group of opposite side of hexagon head bolt 8, and the foreign side 11 of hexagon head bolt 8 is inserted towards the front end detecting foreign side's draw-in groove 2 in frock, upper limit measuring section 4 on front side of detection frock is coordinated with this group opposite side of hexagon head bolt 8, if this group opposite side can fill in upper limit measuring section 4, then can judge that the opposite side size S of this group opposite side does not exceed high limit of size S
the upper limit, for qualified; Otherwise, then defective, foreign side 11 inaccuracy of dimensions of this hexagon head bolt 8 can be judged.If opposite side size S does not exceed high limit of size S
the upper limit, then continue to fill in examination inwards, the lower limit measuring section 5 on rear side of detection frock coordinated with this group opposite side of hexagon head bolt 8, if this group opposite side can be stopped by upper limit measuring section 4, then can judge that the opposite side size S of this group opposite side is not less than lower limit S
lower limitotherwise, then defective, foreign side 11 inaccuracy of dimensions of this hexagon head bolt 8 can be judged.After this group Opposite side survey is qualified, hexagon head bolt 8 is extracted and detects frock rotating, make the detection side wall surface of foreign side's draw-in groove 2 and hexagon head bolt 8 next to organize opposite side corresponding, carry out the detection that next organizes opposite side.After three groups of opposite side have all inspected, if three groups of opposite side are all qualified, then foreign side 11 size qualification of this hexagon head bolt 8, has the opposite side size S of one group of opposite side not meet high limit of size S
the upper limitor lower limit S
lower limit, then foreign side 11 inaccuracy of dimensions of this hexagon head bolt 8, easy to operate, effectively can improve detection efficiency, and structure is simple, cost is low.In the present invention, an embodiment of securing member foreign side detection method and above-mentioned detection method, repeat no more herein.
In the above-described embodiments, frock main body 1 is annular solid, and the foreign side's draw-in groove 2 in frock main body 1 is hexgonal structure, and detection side wall surface 3 is arranged symmetrically with.For in other embodiments of the invention, frock main body 1 and the foreign side's draw-in groove 2 on it all can replace with other shapes, such as square, as long as foreign side's draw-in groove 2 is provided with detection side wall surface 3, and the detection side wall surface 3 on foreign side's draw-in groove 2 also can be unsymmetric structure, such as make the coplanar setting of respective side of detection side wall surface 3 on the wherein side of detection side wall surface 3 on lower limit measuring section 5 and upper limit measuring section 4, make the respective side of detection side wall surface 3 on other side and upper limit measuring section 4 form ledge structure.In addition, in other embodiments, securing member foreign side rapid detection tool can also be provided with other structures in frock main body 1, such as, for the holder, handle etc. of fixing tool main body 1.
