Embodiment Construction

[0053] figure 2 A first embodiment of the control loop 100 according to the invention is shown. The control ring 100 includes a tubular body 110 having an axis of rotation B, which is equipped with a through hole leading out at a first end 120 of the tubular body and a second end 140 opposite to the first end. The ring is made of aluminum, for example. The inner diameter of the ring matches the outer diameter of the shaft 14 of the fastener to be inspected within a tolerance, so that the ring can slide on the shaft 14 without excessive resistance.

[0054] The first end 120 of the body includes two U-shaped notches 122 and 124, and these U-shaped notches correspondingly extend axially from the end 120 through a part of the body 110 to the end wall 126 and the end wall 128. The end walls 126 and 128 extend on parallel planes perpendicular to the axis B and are axially offset from each other. The two notches 122 and 124 are adjacent and have different axial lengths and different...

Abstract

The invention also concerns a method for controlling a fastener with said control ring. The fastener comprises a head and a cylinder shaft extending along the shaft line. The shaft includes at least one coating band parallel to the shaft line, and the band is extended at the cycle width. The ring comprises s cylinder tubular body extending along the rotation shaft line (B) and two opposite pole ends. The first pole end includes two adjacent arc portions, each arc portion has an end wall vertical to the plane of the rotation shaft line (8) of the ring, and the planes of the two walls are not located at the same plane and are offset with the first pole end on the shaft direction. Each arc portion comprises at least one side wall extending along the vertical plane of the rotation shaft (B) of the ring. The width of one arc portion can detect the minimum band width, and the width of the two arc portions can detect the maximum band width. The present invention also considers the method for controlling the fastener through the control ring.

Description

Technical field [0001] The invention relates to a control gauge designed to check whether the dimensional characteristics of a fastener conform to the design scheme of the fastener when leaving the manufacturing line. More specifically, the present invention relates to a control ring for a fastener having a type including an enlarged head and a cylindrical shaft extending along an axis, the shaft including at least one coating parallel to the axis Layer belt. Such fasteners are described in application FR 3 008 754 and are described in Figure 1A with Figure 1B Expressed in. Use this type of fasteners to assemble metal structures and composite structures in aircraft. Background technique [0002] Figure 1A with Figure 1B The above-mentioned metal fastener 10 is shown in an end view and a side view, respectively, and the metal fastener includes a protruding head 12, a cylindrical shaft 14, and a threaded portion 16. In a number of variations, the fastener can include a pull ro...
