Description

Title of the invention: Mounting device for accommodating at least one test specimen and associated test bench

[0001] The present invention relates to a mounting device intended to accommodate at least one test specimen.

[0002] The present invention also relates to a test bench comprising such a mounting device.

[0003] BACKGROUND OF THE INVENTION

[0004] In the field of aeronautics, titanium parts used in aircraft engines are subjected to various stresses.

[0005] Therefore, to evaluate the resistance of these parts, it is known to perform stress corrosion tests on test specimens made of the same titanium as said parts. It should be noted that a test specimen is a manufactured part of standardized dimensions intended to be subjected to at least one test, itself designed to determine the behavior of a material when said material is subjected to a specific stress.

[0006] In a manner known per se, the test specimen is positioned by force on the test bench, so as to be put into flexure, before the corrosion test proper begins.

[0007] Unfortunately, current test benches raise HSE (Health, Safety, Environment) risks related to the positioning of test specimens on the test bench. Indeed, positioning the test specimens requires the use of force, which can lead to risks of specimen ejection, which is dangerous for the operator, as well as pinching or cuts.

[0008] SUBJECT OF THE INVENTION

[0009] The invention aims in particular to provide a solution enabling an operator to carry out a test on at least one test specimen in a safer manner. Summary of the invention

[0010] To this end, the invention provides a mounting device for receiving at least one test specimen, the mounting device comprising a plate having a first receiving area for housing a first end of a given test specimen and having a second receiving area for housing a second end of said given test specimen, the plate comprising a mount and a drawer movably mounted in the mount about at least a first axis, the plate comprising at least a first fastening member arranged through the mount and the drawer to permit a change of relative position along the first axis between the mount and the drawer, at least one of the mount or the drawer comprising a series of orifices each extending in an inclined or orthogonal manner to the first axis, the device comprising at least a second fixing member extending in service between an orifice of said series and an orifice opposite the other of the mount or the drawer.

[0011] Thus, the positioning of the specimen on the invention is more secure since an operator can arrange the specimen on the stage between the two reception areas of the stage without forcing it. Via the two fastening elements, the operator can then modify the relative position between the drawer and the mount to constrain the specimen and, for example, flex it.

[0012] Therefore, HSE risks such as the risks of pinching and / or cutting during the arrangement of the test specimen and / or injuries from ejection of the test specimen are restricted.

[0013] The invention also makes it possible to simplify the assembly of the test specimen.

[0014] Furthermore, the invention advantageously allows the constraint imposed on the specimen to be modulated. Indeed, the fastening element(s) allow the relative position between the mount and the drawer to be adjusted, and thus different constraints to be imposed on the specimen.

[0015] In this way, with the same invention, it is possible to carry out different tests which makes it possible to characterize a part and / or a material in a much more precise way.

[0016] In this way, with the same invention, it is possible to carry out tests with test specimens of different dimensions.

[0017] According to optional features, used individually or in whole or in part in combination: - the first reception area includes a first shoulder and the second reception area includes a second shoulder, the first end of the test specimen being thus housed in service in the first shoulder and its second end, opposite to the first, housed in service in the second shoulder; - the series of holes is a first series of holes, at least one of the mount or drawer comprising a second series of holes and the mounting device comprising at least a third fixing member associated with the second series of holes; - the plate includes at least one graduation system associated with the series of orifices; - each orifice in the series of orifices corresponds to a graduation in the graduation system; - one of the drawer or the mount includes at least one groove.

[0018] The invention also relates to a test bench comprising at least one mounting device.

[0019] A test bench is also proposed comprising at least one support for holding the device on a chassis of the test bench.

[0020] A test bench is also proposed in which the support holder has a tab inserted in the groove.

[0021] A test bench is also proposed comprising at least one pin inserted in the retaining support and bearing against the plate.

[0022] Other features and advantages of the invention will become apparent from the following description of a particular, non-limiting embodiment of the invention. Brief description of the drawings

[0031] With reference to figures 1 to 7, a mounting device 1 according to a particular embodiment of the invention will be described.

[0032] The mounting device 1 comprises a plate 100. The plate 100 comprises on the one hand a mount 110 and on the other hand a drawer 200.

[0033] Mount 110 is in this case hollow as we shall see later.

[0034] The mount 110 comprises a substantially parallelepiped-shaped body which is therefore Here, the body is hollow. It extends lengthwise along a first axis X. It extends widthwise along a second axis Y, the second Y axis being orthogonal to the first. X-axis. The body extends vertically along a third axis Z, the third axis Z being orthogonal to the first axis X and orthogonal to the second axis Y. The height of the mount 110, along the third axis Z, is less than its other dimensions.

[0035] The mount 110 comprises an upper wall 111 and a lower wall 112, opposite the upper wall 111. Preferably, the lower wall 112 is parallel to the upper wall 111.

[0036] Furthermore, the mount 110 comprises a first lateral side 113, a second lateral side 114, a third lateral side 115 and a fourth lateral side 116. Here, the first lateral side 113 is parallel to the third lateral side 115. Similarly, the second lateral side 114 is parallel to the fourth lateral side 116. The various lateral sides 113, 114, 115 and 116 are all connected superiorly by the upper wall 111 and are all connected inferiorly by the lower wall 112.

[0037] Here, the lower wall 112 of the mount 110 is at least partly flat.

[0038] Here, the upper wall 111 of the mount 110 is at least partially flat. Preferably, the upper wall 111 is divided into at least two distinct zones. The first zone 111.1 is at least partially flat. The second zone 111.2 is at least partially flat. The first zone 111.1 is connected to the second 111.2 by means of a first step 130. The first step 130 extends in a plane normal to the first X-axis. The first step 130 defines a first shoulder 160.

[0039] Furthermore, at least one first opening 131 is provided in the upper wall 111. Here, the first opening 131 is provided in the first zone 111.1 of the upper wall 111. Preferably, at least two openings are provided in the upper wall 111. Here, at least two openings are provided in the first zone 111.1 of the upper wall 111. Preferably, the first opening 131 is shaped as a rectangle with rounded edges and / or as an oblong hole. Preferably, the second opening 132 is shaped as a rectangle with rounded edges and / or as an oblong hole. Preferably, the first opening 131 and the second opening 132 are identical. Preferably, the first orifice 131 and the second orifice 132 are arranged symmetrically in the upper wall 111 and, for example, are arranged symmetrically on either side of an axis of symmetry parallel to the first axis X and extending to the center of the upper wall.The first orifice 131 and the second orifice 132 extend parallel to the third Z-axis in this case. The first orifice 131 and the second orifice 132 extend along the entire height of the upper wall 111 so as to open on one side into the inside of the mount 110 and on the other side out of the mount 110.

[0040] The mount 110 also includes at least one first notch 133. Preferably, the first notch 133 is provided in the upper wall 111. Here, the first notch 133 is formed in the first zone 111.1 of the upper wall 111. Preferably, the first notch 133 is flush with or opens at one of its ends into one of the first or second openings 131. Preferably, the first notch 133 extends along the second Y-axis outwards from the mount 110, orthogonally to one of the edges of one of the first or second openings 132. Preferably, the mount 110 also includes a second notch 134. Here, the second notch 134 is identical to the first 133. Preferably, the second notch 134 is flush with or opens at one of its ends into the other of the first or second openings 132. Preferably, the second notch 134 extends along the second axis Y, outwards from the mount 110, orthogonally to one of the edges of the other of the first orifice 131 or the second orifice 132.Here, the first notch 133 is flush at one of its ends with the first orifice 131. Therefore, the second notch 134 is flush at one of its ends with the second orifice 132.

[0041] Furthermore, the first lateral flank 113 extends along the entire length of the mount 110 along the first X-axis. The first lateral flank 113 can be divided into at least two distinct zones. Preferably, the first lateral flank 113 can be divided into at least three distinct zones. A first zone 113.1 of the first lateral flank is at least partially flat. The first zone 113.1 includes at least one first opening 135. Preferably, the first opening 135 has a circular cross-section. For example, the first opening 135 extends through the first zone 113.1 along the second Y-axis. The first opening 135 extends through the entire first zone 113.1 so as to open at one end outside the mount and at the other end inside the mount 110. Here, the first zone 113.1 also includes a second opening 136. The second opening 136 has a circular cross-section.For example, the second opening 136 has a smaller diameter than the first opening 135. For example, the second opening 136 extends through the first zone 113.1 along the second Y-axis. The first opening 136 extends through the entire first zone 113.1 so as to open at one end outside the mount and at the other end inside the mount 110. It is therefore understood that the first opening 135 and the second opening 136 extend side by side in the first zone 113.1.

[0042] A second zone 113.2 of the first lateral flank 113 is adjacent to the first zone 113.1. The first zone 113.1 and the second zone 113.2 are adjacent to the first zone 111.1 of the upper wall 111.

[0043] The first zone 113.1 and the second zone 113.2 jointly define a shoulder. The second zone 113.2 is thus offset from the first zone 113.1 towards the outside of the 110 mount. The shoulder thus defined extends in a plane which here has as its normal the first X axis.

[0044] The second zone 113.2 includes a first groove 140. Preferably, the first groove 140 extends along the entire length of the second zone 113.2 of the first lateral side 113. The first groove 140 thus extends parallel to the first X-axis. The first groove 140 opens at one end onto the first zone 113.1 and at the other end onto the exterior of the mount 110. The first groove 140 is centered along the third Z-axis on the second zone 113.2. The first groove 140 thus defines an upper border 141, adjacent to the first zone 111.1 of the upper wall 111. The first groove 140 also defines a lower border 142, adjacent to the lower wall 112.

[0045] A third zone 113.3 of the first lateral flank 113 is, for its part, adjacent to the second zone 111.2 of the upper wall 111. The third zone 113.3 thus forms a step with the second zone 113.2 to follow the shoulder 160. The third zone 113.3 extends in the continuation of the upper border 141 along the first axis X. An external face defined by the third zone 113.3 and the second zone 113.2 extends here in a plane normal to the second axis Y.

[0046] From then on, the first zone 113.1, the second zone 113.2 and the third zone 113.3 form the first lateral flank 113.

[0047] Preferably, the first zone 113.1 of the first lateral flank 113 is adjacent to the second lateral flank 114. Preferably, the first zone 113.1 of the first lateral flank 113 forms a right angle with the second lateral flank 114.

[0048] The second lateral flank 114 is here planar. It thus extends here parallel to the second Y axis and the third Z axis.

[0049] The second lateral flank 114 includes an opening and more specifically a central opening 150.

[0050] Said opening 150 extends through the second lateral flank 114 along the first axis X. Said opening 150 extends through the entire second lateral flank 114 so as to open at one end outside the mount and at the other end inside the mount 110.

[0051] The opening 150 here has a rectangular cross-section. Preferably, the opening 150 is centered on the second lateral flank 114 along the second Y-axis. Preferably, the central opening 150 is centered on the second lateral flank 114 along the third Z-axis.

[0052] The second lateral flank 114 is adjacent to the third lateral flank 115. Preferably, the third lateral flank 114 forms a right angle with the third lateral flank 115.

[0053] Here, the third lateral flank 115 is identical to the first lateral flank 113. Therefore, everything that has been said above for the first lateral flank 113 is also applicable to the third lateral flank 115.

[0054] In particular, it is thus understood that the third lateral flank 115 comprises a first zone 115.1, a second zone 115.2 and a third zone 115.3.

[0055] It is also understood that the third lateral flank 115 has a second groove 143 and two openings 137 and 138. For example, the third opening 137 is opposite the first opening 135. For example, the fourth opening 138 is opposite the second opening 136.

[0056] The third lateral flank 115 is adjacent to the fourth lateral flank 116. Preferably, the third lateral flank 115 forms a right angle with the fourth lateral flank 116. Symmetrically, the first lateral flank 113 is adjacent to the fourth lateral flank 116. Preferably, the fourth lateral flank 116 forms a right angle with the first lateral flank 113.

[0057] The fourth lateral flank 116 is at least partly planar.

[0058] The fourth lateral flank includes a mouth 139. Said mouth 139 extends through the fourth lateral flank 116 along the first axis X. Said opening 139 extends through the entire fourth lateral flank 116 so as to open at one end outside the mount and at the other end inside the mount 110. Preferably, the opening 139 has a circular cross-section. Here, the opening 139 is opposite the opening 150.

[0059] Therefore, the various sides and walls of the mount 110 jointly delimit a cavity of the mount 110. This cavity is notably accessible via the opening 150 which is the largest hole among the various mouths, orifices and openings of the mount 110.

[0060] As described previously, the turntable 100 also includes a drawer 200.

[0061] The drawer 200 comprises a base 210 and an arm 220. The base 210 extends into The base 210 has a depth along a first axis X'. It extends lengthwise along a second axis Y', which is perpendicular to the first axis X'. It also extends widthwise along a third axis Z', which is perpendicular to both the first axis X' and the second axis Y'. The depth of the base 210, along the first axis X, is less than its other dimensions.

[0062] The base 210 is substantially shaped as a parallelepiped. The base 210 comprises an upper wall 211 and a lower wall opposite the upper wall 211.

[0063] The upper wall 211 includes a second step 230. The second step 230 extends along the entire length of the base 210 along the second axis Y'. The second step 230 defines a second shoulder 260. Therefore, the wall The upper section 211 can be divided into at least two distinct zones. A first zone 211.1 constitutes the upper part of the second shoulder 260. A second zone 211.2 constitutes the lower part of the second shoulder 260.

[0064] The base 210 also includes, among other things, an inner side face 212 and an outer side face 213, opposite the inner side face 212, as well as two lateral sides opposite each other. The two side faces and the two lateral sides each extend between the lower wall and the upper wall 211 and together form a closed frame of the base 210.

[0065] The inner side face 212 is adjacent to the upper wall 211. Preferably, the inner side face 212 forms a right angle with the upper wall 211. Preferably, the inner side face 212 is adjacent to the second zone 211.2 of the upper wall 211. Preferably, the inner side face 212 forms a right angle with the second zone 211.2 of the upper wall 211. The inner side face 212 is at least partially flat.

[0066] The outer side face 213 is adjacent to the upper wall 211. Preferably, the outer side face 213 forms a right angle with the upper wall 211. Preferably, the outer side face 213 is adjacent to the first zone 211.1 of the upper wall 211.

[0067] Preferably, the other faces, walls and sides of the base 210 are at least partly flat.

[0068] The arm 220 is shaped like a parallelepiped. The arm 220 of the drawer 200 extends lengthwise along the first axis X'. The arm 220 extends widthwise along the second axis Y'. The arm 220 extends heightwise along the third axis Z'. The height of the arm 220, along the third axis Z', is less than its other dimensions.

[0069] The arm 220 extends in line with the base 210. Preferably, the arm 220 extends from the inner lateral face 212 of the base 210. Preferably, the arm 220 occupies a central position on the inner lateral face 212 of the base 210. In this way, the arm 220 is centered on the inner lateral face 212 of the base along the second axis Y' and / or the third axis Z'.

[0070] Here, the base 210 and the arm 220 form a single monobloc piece.

[0071] The arm 220 of the drawer 200 comprises an upper wall 221 and a lower wall 222, opposite the upper wall 221. Preferably, the upper wall 221 is parallel to the lower wall 222. Preferably, the upper wall 221 is at least partially flat. Preferably, the lower wall 222 is at least partially flat.

[0072] The upper wall 221 comprises at least two notches. Preferably, the upper wall 221 comprises a plurality of notches 240. For example, the upper wall 221 comprises between two and thirty notches 240. And for example, the upper wall 221 comprises between ten and sixteen notches 240. The notches 240 extend longitudinally along the second axis Y'. Preferably, at least a first portion of the notches 240 is flush with and / or at least partially reaches a first edge 235 of the arm 220. Preferably, at least a second portion of the notches 240 is flush with and / or at least partially reaches a second edge 236 of the arm 220 that is opposite the first edge 235. Preferably, the notches 240 are arranged in this way on both sides of the upper wall 221 of the arm 220 of the drawer 200. Preferably, an equivalent number of notches 240 are arranged on both sides of the upper wall 221. The notches 240 thus form a first alignment of notches arranged on one side of the arm 220 and a second alignment of notches arranged on the other side of the arm 220.

[0073] Preferably, the notches 240 of the first alignment are not aligned with the notches 240 of the second alignment. In particular, the notches 240 of the first alignment are not aligned with the notches 240 of the second alignment along the second Y' axis. Preferably, the notches 240 of the arm 220 are offset on either side.

[0074] Preferably, the notches 240 of the first alignment are all spaced two by two with the same interval value and / or the notches 240 of the second alignment are all spaced two by two with the same interval value. Preferably, the interval value of the first alignment and the interval value of the second alignment are identical.

[0075] Preferably the offset between the notches 240 of the first alignment and the notches 240 of the second alignment is equal to half of this interval value.

[0076] Here, a distance of between 5 and 15 millimeters (mm) separates the notches 240 of the same alignment, and for example a distance of 10 millimeters. Therefore, and since the notches 240 of the first alignment are offset from the notches 240 of the second alignment, each notch 240 of the first alignment is offset by 5 millimeters (along the first axis X') from a notch 240 of the second alignment.

[0077] The notches 240 form part of a graduation system for estimating the relative position between the drawer 200 and the mount 110. Therefore, each notch 240 corresponds to a numerical value. Each numerical value is inscribed on the upper wall 221 of the arm 220. Each numerical value is inscribed opposite the corresponding notch 240.

[0078] The arm 220 also includes a first lateral flank 223, a second lateral flank 224, a third lateral flank 225 and a fourth lateral flank 226.

[0079] The first side 223, the second side 224, the third side 225 and the fourth side 226 are all connected superiorly by the upper wall 221 of the arm 220 and are all connected inferiorly by the lower wall 222 of the arm 220.

[0080] The first lateral flank 223 is at least partially planar. The first lateral flank 223 comprises a first series of orifices 270. The orifices 270 extend along the second axis Y'. Preferably, the orifices 270 extend orthogonally or inclinedly to the first axis X'. Preferably, the orifices 270 have a circular cross-section. Preferably, all the orifices 270 in the first series have the same diameter. The orifices 270 extend into the arm 220 through the first lateral flank 223 along the second axis Y'. The orifices 270 open at one end outside the arm 220 and are blind at the other end.

[0081] For example, between two and fifteen orifices 270 pass through the first lateral flank 223, and for example, between four and eight orifices 270. Preferably, the number of orifices 270 is equivalent to the number of notches 240 in the first alignment. Therefore, each orifice 270 corresponds to a notch 240 present at the first edge 235 of the upper wall 221. Furthermore, the orifices 270 are spaced from each other by the same interval. Preferably, the interval separating each of the orifices 270 is identical to the interval separating the notches 240 in the first alignment.

[0082] The first lateral flank 223 is adjacent to the second lateral flank 224. Preferably, the first lateral flank 223 forms a right angle with the second lateral flank 224.

[0083] The second lateral flank 224 is adjacent to the third lateral flank 225. Preferably, the second lateral flank 224 forms a right angle with the third lateral flank 225. The third lateral flank 225 is parallel to the first lateral flank 223.

[0084] Preferably, the third lateral flank 225 is similar to the first lateral flank 223.

[0085] Therefore, the third lateral flank 225 is at least partially planar. The third lateral flank 225 comprises a second series of orifices 270. The orifices 270 extend along the second axis Y'. Preferably, the orifices 270 extend orthogonally or inclinedly to the first axis X'. Preferably, the orifices 270 have a circular cross-section. Preferably, all the orifices 270 of the second series have the same diameter. Preferably, all the orifices 270 of the first series and all the orifices 270 of the second series have the same diameter. The orifices 270 extend into the arm 220 through the third lateral flank 225 along the second axis Y'. The orifices 270 open at one end outside the arm 220 and are blind at the other end.

[0086] For example, between two and fifteen orifices 270 pass through the third lateral flank 225 and for example between four and eight orifices 270.

[0087] Preferably, the number of holes 270 is equivalent to the number of notches 240 in the second alignment. Therefore, each hole 270 corresponds to a notch 240 present on the second edge 236 of the upper wall 221. Furthermore, the holes 270 are spaced from each other by the same interval. Preferably, the interval separating each of the orifices 270 is identical to the interval spacing the notches 240 of the second alignment.

[0088] Therefore, the arm 220 has a first series of orifices 270 on one side and a second series of orifices 270 on the other side.

[0089] The orifices 270 thus form a first series of orifices arranged on one side of the arm 220 and a second series of orifices arranged on the other side of the arm 220.

[0090] Preferably, the orifices 270 of the first series are not aligned with the orifices 270 of the second series. In particular, the orifices 270 of the first series are not aligned with the orifices 270 of the second series along the second axis Y'. Preferably, the orifices 270 of the arm 220 are offset on either side.

[0091] Preferably, the orifices 270 of the first series are all spaced two by two with the same interval value and / or the orifices 270 of the second series are all spaced two by two with the same interval value. Preferably, the interval value of the first series and the interval value of the second series are identical.

[0092] The third lateral flank 225 is adjacent to the fourth lateral flank 226. Here, the fourth lateral flank 226 of the arm 220 coincides with a portion of the inner lateral face 212 of the base 210. Furthermore, a channel 280 is provided inside the drawer 200. Said channel 280 extends through the entire drawer 200. The central channel 280 is thus cut into the arm 220 and then into the base 210.

[0093] More specifically, here, said channel 280 extends so as to open at one end onto the second lateral side 224 and at the other end onto the outer lateral face 213 of the base 210. The channel 280 extends longitudinally along the first axis X'. The channel 280 has a circular cross-section. The channel 280 is, for example, a central channel. Thus, the channel 280 is centered in the drawer 200 along the second axis Y' and / or the third axis Z'.

[0094] By opening at the level of the outer lateral face 213, the channel 280 thus forms a first opening 250 for said outer lateral face 213. In this way, the first opening 250 is centered on the outer lateral face 213 along the second axis Y' and / or the third axis Z'.

[0095] By opening at the level of the second lateral flank 224, the channel 280 thus forms a second opening 255 for said second lateral flank 224. In this way, the second opening 255 is centered on the second lateral flank 224 along the second axis Y' and / or the third axis Z'.

[0096] It is noted that the various orifices 270 do not open into the channel 280.

[0097] The drawer 200 also includes a threaded ring 290. Preferably, the threaded ring 290 extends at least partially into the channel 280. Therefore, the threaded ring 290 extends longitudinally along the first axis X'. More precisely, the threaded ring 290 externally follows the shape of the circumference of the central channel 280.

[0098] Preferably, the threaded ring 290 is arranged here entirely within the arm 220. Preferably, the threaded ring 290 does not extend beyond the third orifice 270 of at least one of the series of orifices 270. Preferably, the threaded ring 290 is arranged so as to present a face aligned or recessed with the second lateral flank 224.

[0099] The plate 100 comprises, as described above, the mount 110 and the drawer 200. Preferably, the drawer 200 is mounted movably in the mount 110. For example, the drawer 200 is mounted movably in translation in the mount 110 and, for example, is mounted movably in translation along the first X axis.

[0100] When the drawer 200 is mounted in the mount 110, we then preferably have the first X axis coincide with the first X' axis, the second Y axis coincide with the second Y' axis, the third Z axis coincide with the third Z' axis.

[0101] At least a portion of the drawer 200 slides inside the mount 110, along the first axis X. More precisely, at least a portion of the arm 220 slides in the mount 110 at its opening 150. In other words, the opening 150 receives at least part of the arm 220 of the drawer 200. Therefore, at least a portion of the arm 220 of the drawer 200 is housed in the cavity of the mount 110.

[0102] It is understood that the translation of the arm 220 within the mount 110 is here the only movement allowed.

[0103] Therefore, the opening 150 of the mount 110 and the arm 220 of the drawer form, here, a tenon / mortise assembly. Indeed, the opening 150 of the mount 110 can be considered a mortise. The arm 220 of the drawer 200, for its part, can be considered a tenon.

[0104] More specifically, when the arm 220 of the drawer 200 slides in the mount 110, the upper wall 221 of the drawer 200 is at least partly opposite the first zone 111.1 of the upper wall 111 of the mount 110.

[0105] In the example shown in [Fig. 4], which is not limiting, one of the notches 240 of the second alignment is located opposite the second notch 134 of the mount 110. Furthermore, said notch 240 is visible at the level of the second hole 132 of the mount 110. Moreover, the numerical value associated with said notch 240 is also visible at said second hole 132 of the mount 110. It is therefore understood that one of the notches 240 of the first alignment is offset from the first notch 133 of the mount 110.

[0106] Conversely, if one of the notches 240 of the first alignment is opposite the first notch 133, it follows that one of the notches 240 of the second alignment is offset from the second notch 134 of the mount 110. Therefore, Alignment of a notch 240 with one of the first notch 133 or second notch 134 is only possible on one side of the plate 100.

[0107] Furthermore, if one of the notches 240 of the first alignment is located opposite the first notch 133, one of the notches 240 in question is visible at the level of the first orifice 131 of the mount 110. Moreover, the numerical value associated with one of the notches 240 in question is also visible at the level of said first orifice 131 of the mount 110.

[0108] It is thus understood that an operator can view via the ports 131 and 132 of the mount 110 one or more notches 240 and / or one or more numerical values ​​of the drawer 200.

[0109] In this way, the operator can easily align one of the notches of the mount 110 with one of the notches 240 of the drawer 200. He can also deduce from this the distance of the relative position between the mount 110 and the drawer 200.

[0110] The numerical value associated with the notch 240 opposite the notch of the mount 110 is for example representative of the distance separating the first shoulder 160 of the mount 110 from the second shoulder 260 of the drawer 200 and in particular of the distance separating said shoulders along the first axis X.

[0111] For example, the plate 100 is shaped so that the distance between the first shoulder 160 and the second shoulder 260 can extend from 70 mm to 200 mm. And for example, the plate 100 is shaped so that the distance between the first shoulder 160 and the second shoulder 260 can extend from 80 mm to 170 mm.

[0112] Furthermore, when the arm 220 of the drawer 200 slides in the mount 110, the lower wall 222 of the arm 220 is at least partly opposite the lower wall 112 of the mount 110.

[0113] Furthermore, when the arm 220 of the drawer 200 slides in the mount 110, the first lateral flank 223 of the arm 220 is at least partly opposite the first flank 113 of the mount 110. Preferably, the first lateral flank 223 of the arm 220 is at least partly opposite the first zone 113.1. For example, the first lateral side 223 of the arm 220 is at least partly opposite the first zone 113.1 and the second zone 113.2 of the first lateral side 113. Therefore, the first mouth 135 of the mount 110 is at least partly opposite one of the orifices 270 of the first series of the drawer 200 if a notch 240 of the first alignment is opposite the notch 133 or the third mouth 137 is at least partly opposite one of the orifices 270 of the second series of the drawer 200 if a notch 240 of the second alignment is opposite the notch 134.

[0114] Furthermore, when the arm 220 of the drawer 200 slides in the mount 110 and depending on the relative position of the drawer 200 with respect to the mount 110, the second lateral flank 224 of the drawer moves closer to or further away from the fourth lateral flank 116 of the mount 110. Therefore, channel 280 is opposite mouth 139 of mount 110. In the present case, channel 280 is coaxial with mouth 139 when drawer 200 is in place in mount 110.

[0115] Furthermore, when the arm 220 of the drawer 200 slides in the mount 110, the third lateral flank 225 of the arm 220 is at least partially aligned with the third lateral flank 115 of the mount 110. Preferably, the third lateral flank 225 of the arm 220 is at least partially aligned with the first zone 115.1. For example, the third lateral flank 225 of the arm 220 is at least partially aligned with the first zone 115.1 and the second zone 115.2 of the third lateral flank 115.

[0116] Furthermore, when the arm 220 of the drawer 200 slides in the mount 110 and depending on the relative position of the drawer 200 vis-à-vis the mount 110, the base 210 of the drawer approaches the second lateral side 114 of the mount 110.

[0117] With reference to [Fig. 6], when the arm 220 of the drawer 200 is slid to its maximum extent in the cavity of the mount 110, the second lateral side 224 of the drawer abuts against the fourth lateral side 116 of the mount 110. Furthermore, when the arm 220 is slid to its maximum extent in the cavity of the mount 110, the second lateral side 114 of the mount 110 abuts against the base 210. More precisely, when the arm 220 is slid to its maximum extent in the cavity of the mount 110, the second lateral side 114 of the mount 110 abuts against the inner lateral face 212 of the base 210. Consequently, the cavity of the mount 110 is entirely occupied by the arm 220 of the drawer 200.

[0118] With reference to [Fig. 5], the plate 100 also includes at least one first fastening member 300. The first fastening member 300 extends longitudinally along the first axis X. The first fastening member 300 is arranged through the mount 110 and the drawer 200. More precisely, the first fastening member 300 extends through the mouth 139 of the mount 110 and the central channel 280 of the drawer 200. It is therefore understood that the first fastening member 300 is housed, at least partially, in the cavity of the mount 110 and in the central channel 280 of the drawer 200. More precisely, the first fastening member 300 extends through the threaded ring 290. When the arm 220 of the drawer 200 is slid to its maximum extent in the cavity of the mount 110, the first the fixing element 300 can also extend through the first opening 250 or be flush with said first opening 250.

[0119] For example, the first fastening member 300 may be a screw whose head rests against the fourth lateral side 116 of the mount and whose threaded shank extends as described above by cooperating with the threaded ring 290 to allow relative movement between the drawer 200 and the mount 110. The first fastening member 300 is, for example, a worm screw. Here, a washer 310 is arranged between the first fastening member 300 and the fourth lateral side 116 of the mount 110.

[0120] The first fixing member 300 advantageously allows a modification of the relative position of the drawer 200 vis-à-vis the mount 110, along the first axis X and to maintain the mount 110 in relative position vis-à-vis the drawer 200.

[0121] It is noted that the first fixing member 300 also allows here to guide the movement of the mount 110 in the drawer 200.

[0122] It is also noted here that the first fixing member 300 also serves as an anti-rotation means for the mount 110 in the drawer 200.

[0123] The plate 100 also includes at least one second fastening member 350. The second fastening member 350 extends longitudinally along the second Y-axis. Here, the second fastening member 350 passes through at least the mount 110. More precisely, the second fastening member 350 passes through one of the first opening 135 or the third opening 137. If one of the orifices 270 of the first set of orifices 270 or the second set of orifices 270 is opposite the opening in question, then the second fastening member 350 is shaped so that it can also be inserted through said orifice 270. In this way, when the second fastening member 350 is inserted both into the associated opening and into an opposite orifice 270, it temporarily blocks the relative position between the drawer 200 and the mount 110. It is sufficient to retract the second fixing element 350 to release the translation of the drawer 200 in the mount 110.

[0124] Preferably, the second fastening member 350 is a pin, but can also be a screw or a threaded rod.

[0125] Preferably, the plate 100 includes at least one third fastening element 350. Preferably, the third fastening element 350 is identical to the second fastening element 350. Preferably, the third fastening element 350 is a pin, but may also be a screw or a threaded rod. In practice, one of the second fastening elements is associated with the opening 135 and the other with the opening 137 so that it can potentially be inserted into one of the holes 270 in the alignment considered.

[0126] The mounting device 1 as described is intended to hold at least one test specimen 400, for example, a titanium test specimen 400. Preferably, the mounting plate 100 of the mounting device 1 is provided with a first and a second receiving area, said first and second receiving areas being intended to hold said test specimen 400. Accordingly, one end of the test specimen 400 is housed in the first receiving area and a second end of the test specimen 400 is housed in the second receiving area. More precisely, the first receiving area described corresponds to the first shoulder 160 of the mount 110 and the second receiving area described corresponds to the second shoulder 260 of the drawer 200. From then on, the first end of the specimen 400 is arranged in the first shoulder 160 and the second end of the specimen 400 is arranged in the second shoulder 260.

[0127] During operation, the operator moves the drawer 200 into the mount 110 and then temporarily locks it in position in the mount 110 using the second or third locking member so that the two receiving areas are separated from each other. For example, the operator moves the drawer 200 as far apart as possible in the mount 110 using the opening 270 closest to the side 224 of the arm 220.

[0128] The operator can then easily arrange the test specimen 400 in the mounting device 1 since it is then not or only slightly constrained as can be seen in [Fig.1].

[0129] Then the operator removes the fixing member of the drawer 200 and modifies the relative position between the drawer 200 and the mount 110. The operator can then bring the two reception areas closer or further together to constrain the specimen 400 more or less, it being understood (as illustrated in [Fig.6]) that when the arm 220 of the drawer 200 is slid to the maximum in the cavity of the mount 110, the constraints exerted on the specimen 400 are maximum.

[0130] It is recalled that the operator can advantageously use the graduation system represented on the arm 220 of the drawer 200 when applying stress to the specimen 400. The graduation system therefore constitutes a reference for the application of stresses to the specimens 400.

[0131] Once the desired constraint has been applied, the operator then temporarily locks the drawer 200 in position in the mount 110 once again, via the second or third fixing member.

[0132] Whatever the applied stress, the various fastening elements guarantee the stability of the assembly.

[0133] Furthermore, the mounting device 1 allows various constraints to be applied to a test specimen.

[0134] For example, the mounting device 1 can be defined so that when the arm 220 of the drawer 200 is slid to the maximum in the cavity of the mount 110, the stresses exerted on the specimen 400 are those of the rupture of the specimen 400 or are close to the rupture of the specimen.

[0135] For example, the mounting device 1 can be defined so that when the arm 220 of the drawer 200 is slid to the minimum in the cavity of the mount 110, the stresses exerted on the specimen 400 are zero.

[0136] Advantageously, the mounting device 1 is resistant to high temperatures and / or exposure to chemicals.

[0137] Advantageously, the mounting device 1 is configured to simultaneously accommodate a plurality of test specimens 400. These test specimens are thus arranged side by side in the mounting device 1 so as to extend all between the two reception areas.

[0138] The mounting device 1 as described is integrated into a test bench 500 more visible in [Fig.7].

[0139] The test bench 500 includes at least one chassis and at least one support 380 for mounting the device 1 to the chassis.

[0140] The retaining support 380 includes, for example, a base 382 from which a tongue 381 extends. Preferably, the tongue 381 is perpendicular to the base 382. The retaining support 380 thus has a T-shaped cross-section.

[0141] The base 382 is integral with the chassis and / or is one piece with the chassis.

[0142] The retaining bracket 380 is intended to be housed in one of the groove 140 or groove 143 of the mount 110 to connect the mounting device 1 to the chassis. More specifically, it is the tab 381 that is inserted into said groove.

[0143] Preferably, the retaining support 380 can slide in the associated groove (preferably along the first X axis).

[0144] When the retaining device 1 is in position in the groove, the tongue 381 extends lengthwise along the first X axis. The tongue 381 extends widthwise along the second Y axis. Furthermore, the base 382 extends lengthwise along the first X axis. The base 382 extends widthwise along the third Z axis.

[0145] The retaining support 380 also includes a pin 390. The pin 390 is, for example, arranged on the tab 381. The pin 390 extends along the third axis Z when the mounting device 1 is arranged on the retaining support 380.

[0146] Preferably, the test bench 500 comprises at least two retaining supports 380. Preferably, the two retaining supports 380 are identical. Therefore, a first retaining support 380 is intended to be housed in the first groove 140. A second retaining support 380 is intended to be housed in the second groove 143. More specifically, the tab 381 of the first retaining support 380 is intended to be housed in the first groove 140 of the mount 110. More specifically, the tab 381 of the second retaining support 380 is intended to be housed in the second groove 143 of the mount 110.

[0147] In service, to link the retaining device 1 to the test bench 500, the operator slides the tabs 381 of the retaining supports 380 into the associated grooves until the pins 390 come into contact with the plate 100 and, for example, come into contact with the mount 110.

[0148] It is therefore very simple for an operator to link the holding device to the test bench 500.

[0149] Of course, the invention is not limited to the embodiment described but encompasses any variant falling within the scope of the invention as defined by the claims.

[0150] In particular, although here the drawer arm carries the first and second sets of holes, it is entirely conceivable that the mount carries the first and second sets of holes. Therefore, although here the mount comprises the first, second, third, and fourth openings, it is entirely conceivable that the drawer arm comprises the first, second, third, and fourth openings.

[0151] Although here the test specimen is made of titanium, it is entirely possible to carry out this type of test on other materials.

[0152] Of course, instead of the numerical values ​​of the graduation system, any other legends characterizing the relative position between the drawer and the mount may be associated with the holes in the mount: alphanumeric characters, references, symbols, ...
