Abstract

The invention relates to protractors for ultrasound which cannot be used for angle sensors, for detecting defects in metals. It comprises: a graduated ruler made of plexiglass 1 drilled at the zero point to make it movable in an angular sector on the protractor 2 which is itself also drilled for assembly of the article 1 and 2, by a pin 3.

Description

La présents invention concerne les rapporteurs pour contrôle des pièces ou soudure par ultra-sons,perméttant de donner la position des défauts dans les soudures ou métaux. En effet, les réglesultra-sons traditinnelles donnent la profondeur et la position du ou des difauts,mais pas la position. Ce rapporteur donne la profondeur et la position du ou des défauts dans les pièces contrôlées en palpeur d'angle . Permet de faire gagner une heure au moins pas jour au contrôleur ultra-sons,qui na se trouve pas obligé de faire pour chaque palpeur d'angle un graphique sur papier milliuétré,qui donne des inconvénients lorsqu'il se trouve sur un chantier sale ( voirgraisse,eau,peinture franche ). The present invention relates to reporters for control of parts or ultrasonic welding, allowing to give the position of faults in welds or metals. Indeed, the traditional ultra-sound rules give the depth and the position of the fault (s), but not the position. This protractor gives the depth and the position of the defect (s) in the parts checked by an angle probe. Allows the ultrasonic controller to save at least one hour a day, who does not have to make a graph on graph paper for each angle probe, which gives disadvantages when it is on a dirty site ( see grease, water, clean paint).

Ce genre de rapporteur supprime tout ces inconvénients,car un coup de chiffon le maintien toujours propre,et quelque soit les conditions de travail . T:'import2nce de ce--- type de rapporteur en plexiglas transparent,et que plagié sur un plan en coupe-de la piece à contrôler,il indique la position et la forme du défaut éventuel,en considèrent que le point zéro du rapporteur et le point d'emergence du palpeur d'angle et que par sa forme le rapporteur peut servir de réglette qui est indispensable au contr81eur ultra-sons.Ce rapporteur pour contrôle par ultra-sons donne une garantie sur les contrôles et un gain de temps au contr8leur,en effet la réglette ( 1 fig 3 ) étant mobile sur le rapporteur ( 2 fig 3 ) par un axe ( 4 fig 3 ) le rapporteur et la règlette étant percée au point zéro ( fig 1 et 2 ) le contrôleur peut régler l'angle de sa réglette ( 1 fig 1 ) sur le rapporteur ( 2 fig 3 ) suivant l'angle qu'il veut,celui-ci étant gradué ( il fig 2 ) en degrès,les graduations en cm et mm ( 12 fig 1 ) donne le chemin parcouru par les ultra-sons . Les graduations donnent ( i1 fig 2 ) l'angle du palpeur,les graduations ( 8 et 10 fig 2 ) donnent la profondeur de l'écho ultra-sonore,la graduation sur la face ( 5 fig 2 ) donne l'aplombrde l'écho ultra-sonore vu du dessus de la pièce . De part sa forme et sa grandeur et de sa composition il est facile au contrôleur de toujours l'avoir sur ui,en toute circonstance. This kind of protractor removes all these disadvantages, because a piece of cloth always keeps it clean, and whatever the working conditions. T: 'import2nce of this --- type of transparent plexiglass protractor, and that plagiarized on a sectional plane of the piece to be checked, it indicates the position and the shape of the possible defect, consider that the zero point of the protractor and the point of emergence of the angle probe and that by its shape the protractor can serve as a strip which is essential for the ultrasonic controller. This protractor for ultrasonic control gives a guarantee on the controls and saves time to the controller, in fact the strip (1 fig 3) being movable on the protractor (2 fig 3) by an axis (4 fig 3) the protractor and the strip being pierced at zero point (fig 1 and 2) the controller can adjust the angle of its strip (1 fig 1) on the protractor (2 fig 3) according to the angle it wants, this one being graduated (it fig 2) in degrees, the graduations in cm and mm (12 fig 1) gives the path traveled by the ultrasound. The graduations give (i1 fig 2) the angle of the probe, the graduations (8 and 10 fig 2) give the depth of the ultrasonic echo, the graduation on the face (5 fig 2) gives the depth of the ultrasonic echo seen from above the room. Due to its shape and size and its composition it is easy for the controller to always have it on him, in all circumstances.

Claims

CLAIM

1 - Angle protractor for ultrasonic control of parts or welds characterized in that the angle protractor (2 fig 2) is made of rigid and transparent plastic, as well as its slide (1 fig 7).

2 - According to the preceding claim n 1 in that the strip (1 fig 1) graduated in mm and in cm pierced at the zero point (3 fig 1let 3) to pass a bolt - 4 fig 3) which will serve as an axis with a nut to serve as a blocking on the protractor (2 fig 2).

3 - Characterized according to claims 1 to 2 in that the graduation of the strip (1 fig 1 and 3) gives the path traveled by ultrasound in the room to be checked.

4 - Characterized according to claims 1 to 3 in that the slide and the protractor have an enlargement of the same shape and in the same place to allow the drilling at zero point (3 fig 1 to 3) 5 - Characterized according to the claims from 1 to 4 in that the graduations in mm and in cm (5 and 7 fig 2 and 3) give the position of the ultrasonic echo seen from above or from above 6 - Carautérisès according to the preceding claims from 1 to 5 in that the graduations in degrees - it fig 2) give the angle of the ultrasonic probe.

7 - Characterized according to the preceding claims from 1 to 6 in that the nut and its bolt blocks the slide on the protractor at the desired angle 8 - Characterized according to the preceding claims from 1 to 7.

in that the graduation (8 and 10 fig 2 and 3) gives the depth of the ultrasonic echo 9 - Characterized according to the preceding claims from 1 to 8 in that considering that the zero point of the slide and the protractor assembled by their axis (4 fig 3) as the point of emergence of the Troublemaker and placed on a plane. in section or on the part to be checked, it is easy to determine the possible defect (s) of the part to be checked with certainty
