Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0048] The double-column tensile testing machine is a device used for tensile testing, referred to as a tensile machine in this application. Its working spindle always remains upright and moves in the vertical direction to perform tensile testing. The component to be tested 100 in this application is a power module. The specific parts that need to be tested in the power module are several terminal holes 101 on both sides of the power module. In the tensile test of the terminal holes 101, it is often necessary to perform comprehensive tests in multiple directions to fully ensure that the strength of the terminal holes 101 meets the standards. Since the working spindle of the tensile machine has a single movement direction, in order to achieve multi-directional tensile testing of the terminal holes 101, this application changes the clamping method of the component to be tested 100 to meet the test requirements. Among them, the opposite sides of the power module are referred to as the front side 102 and the back side 103 in this application.
[0049] At the same time, if Figure 1 As shown, the terminal hole 101 usually needs to be tensile tested in six directions: +X, -X, +Y, -Y, +Z and -Z. The +X, -X, +Y and -Y directions are all radial directions of the terminal hole 101, +X is opposite to -X, +Y is opposite to -Y, and the axis where +X and -X are located is perpendicular to the axis where +Y and -Y are located; and +Z and -Z are axial directions of the terminal hole 101, +Z is opposite to -Z. It can be understood that +X, -X, +Y, -Y, +Z and -Z are only codes for clearly indicating directions in this application, and corresponding changes can be made in actual applications.
[0050] like Figure 2 and Figure 3As shown, the embodiment of the present application provides a tensile test fixture, which includes a first test seat 200 and a second test seat 300. The first test seat 200 assists the tensile machine to test the tensile force in the radial direction of the terminal hole 101, and the second test seat 300 assists the tensile machine to test the tensile force in the axial direction of the terminal hole 101.
[0051] In order to facilitate the installation of the first test seat 200 or the second test seat 300 on the tensile machine, the double-column tensile testing machine needs to be improved in a targeted manner. Specifically, the upper and lower jaw seats connected to the tensile machine are disassembled, the upper jaw seat applies tension to the component to be tested 100, and the lower jaw seat is used to support the component to be tested 100, and the steel columns in the upper and lower jaws and their fast-changing through-hole characteristic structures are retained.
[0052] like Figure 2 and Figure 3 As shown, in some examples, the first test seat 200 includes a first connecting component 201, and the second test seat 300 includes a second connecting component 301. The first connecting component 201 and the second connecting component 301 are both used to connect to the tensile machine, wherein the first connecting component 201 and the second connecting component 301 are both substantially formed as a tubular structure, and the first connecting component 201 and the second connecting component 301 are plugged into the steel column of the jaw seat on the tensile machine.
[0053] Furthermore, the first connecting component 201 and the second connecting component 301 are both provided with a plurality of test seat mounting structures, and the test seat mounting structures are used to mount the first test seat 200 or the second test seat 300 on the tensile machine. Each test seat mounting structure is used to match the mounting hole of the tensile machine, that is, the through-hole characteristic structure. When different test seat mounting structures match the through-hole characteristic structure, the angle of the first test seat 200 or the second test seat 300 can be adjusted, so as to facilitate the connection between the first test seat 200 and the component to be tested 100, and also facilitate the connection between the second test seat 300 and the component to be tested 100.
[0054] At the same time, a single test socket installation structure includes a group of connection holes 305. Specifically, there are two connection holes 305 in a group of connection holes 305. Each connection hole 305 penetrates the side wall of the first connection component 201 or the second connection component 301. The two connection holes 305 in the group are located on opposite sides of the first connection component 201 or the second connection component 301 and are arranged coaxially. When a group of connection holes 305 are all connected to the through-hole feature structure, the test socket installation structure matches the through-hole feature structure, and fasteners such as pins are used to pass through the group of connection holes 305 and the through-hole feature structure to complete the installation process of the first test socket 200 or the second test socket 300.
[0055] It is understandable that when the first connecting component 201 or the second connecting component 301 has two test seat mounting structures, there are two groups of connection holes 305 on the side wall of the first connecting component 201 or the second connecting component 301, that is, four connection holes 305, and the axial directions of the two groups of connection holes 305 are at a first angle. Specifically, the first angle is set to 90°, so when the first test seat 200 or the second test seat 300 is installed on the tensile machine with different test seat mounting structures, the angle of the first test seat 200 or the second test seat 300 changes by 90° to adapt to different clamping forms of the component 100 to be tested, thereby improving the versatility of the tensile test tooling.
[0056] like Figure 2 As shown, in some examples, the first test socket 200 also includes a first test assembly, which includes a first contact component 202. The first contact component 202 is formed as a rod-shaped structure and is inserted into the terminal hole 101 so that the first contact component 202 contacts the inner wall of the terminal hole 101, thereby facilitating the first contact component 202 to transfer the pulling force to the terminal hole 101, thereby completing the pulling test process.
[0057] Furthermore, when testing the tension in the radial direction of the terminal hole 101, since the main axis of the tensile machine moves in the vertical direction, the component to be tested 100 needs to be placed upright, and the terminal hole 101 is also in an upright state. To ensure that the first contact member 202 can pass through the terminal hole 101, the first contact member 202 is arranged horizontally.
[0058] The first test assembly further includes a support frame, which supports the first contact component 202 and ensures that the first contact component 202 is arranged horizontally. The support frame includes a mounting portion 203 and an extension portion 204. The mounting portion 203 is used to connect the first connection component 201. The extension portion 204 is connected to the mounting portion 203 at an angle and extends in the direction of the device to be tested 100. Specifically, two extension portions 204 are provided and kept vertical. There is a gap between the two extension portions 204 to form a accommodating space for the device to be tested 100. The first contact component 202 is connected between the two extension portions 204 and kept horizontal.
[0059] It is understandable that when the first test seat 200 performs a tensile test in the radial direction of the terminal hole 101, part of the structure of the component to be tested 100 will be in the accommodation space. At the same time, each terminal hole 101 is located on both sides of the length direction of the component to be tested 100, but the specific positions of each terminal hole 101 are still different. In order to ensure that the first test seat 200 can perform a radial tensile test on all terminal holes 101, it is necessary to reserve a sufficient volume of accommodation space, and the depth of the accommodation space is greater than the length of the component to be tested 100, that is, when the first test seat 200 is in a vertical state, the distance from the end of the extension portion 204 to the mounting portion 203 in the vertical direction is greater than the length of the component to be tested 100.
[0060] In addition, the extension part 204 is provided with a contact component mounting structure, which includes a first plug hole and a second plug hole, which are respectively provided on the two extension parts 204. The first plug hole is a light hole, and the second plug hole is a threaded hole, and the first contact component 202 passes through the first plug hole and is threadedly connected with the second plug hole.
[0061] like Figure 3 As shown, in some examples, the second test socket 300 also includes a second test assembly, the second test assembly includes a second contact component, the first contact component 202 is inserted into the terminal hole 101, and contacts the edge of the terminal hole 101, so that the second contact component transfers the pulling force to the terminal hole 101, thereby completing the pulling test process.
[0062] Furthermore, when testing the tension in the axial direction of the terminal hole 101, since the main axis of the tensile machine moves in the vertical direction, the component 100 to be tested can be placed horizontally. To ensure that the second contact member can pass through the terminal hole 101, the second contact member is arranged vertically.
[0063] The second test assembly further includes a mounting component 302, and the second contact component is connected to the mounting component 302. The second contact component includes an insertion portion 303 and a contact portion 304 connected to each other, the insertion portion 303 is vertically arranged and inserted into the terminal hole 101, and when the insertion portion 303 passes through the terminal hole 101, the insertion portion 303 is installed with a contact portion 304 larger than the size of the terminal hole 101, so that the contact portion 304 is in contact with the edge of the terminal hole 101.
[0064] Specifically, the inserting portion 303 includes a screw, and the contacting portion 304 includes a nut. The nut is screwed into the screw until it contacts the edge of the terminal hole 101 , thereby completing the connection between the second test socket 300 and the device to be tested 100 .
[0065] like Figure 4 , Figure 5 and Figure 6As shown, in some examples, the tensile testing tool further includes a mounting base 400 , and the mounting base 400 is combined with the component to be tested 100 as a whole, so as to facilitate the component to be tested 100 to remain horizontal or vertical.
[0066] The mounting seat 400 is provided with a test piece mounting structure, a horizontal mounting structure and a vertical mounting structure. The test piece mounting structure is used to mount the component to be tested 100 so that the mounting seat 400 and the component to be tested 100 form a whole.
[0067] Further, when the mounting base 400 adopts a horizontal mounting structure, the mounting base 400 and the component to be tested 100 remain horizontal, which is convenient for testing the tensile force in the axial direction of the terminal hole 101. When the mounting base 400 adopts a vertical mounting structure, the mounting base 400 and the component to be tested 100 remain vertical, which is convenient for testing the tensile force in the radial direction of the terminal hole 101.
[0068] In addition, since the thickness of the middle part of the DUT 100 is relatively large and the thickness of the terminal hole 101 is relatively small, in order to allow the mounting seat 400 to avoid the thicker part of the DUT 100 and avoid structural interference, a first avoidance structure 401 is provided in the middle part of the mounting seat 400. Specifically, the first avoidance structure 401 is formed as a groove-shaped structure for accommodating the thicker part of the middle part of the DUT 100.
[0069] like Figure 7 As shown, in some examples, the tensile testing tool further includes a direction adjustment component 500 , and the direction adjustment component 500 is used to connect the mounting base 400 to keep the mounting base 400 and the component to be tested 100 upright.
[0070] The direction adjustment component 500 includes a fixing portion 501 and a connecting portion 502, wherein the fixing portion 501 is connected to the connecting portion 502 at an angle, and the fixing portion 501 is always kept horizontal. The connecting portion 502 is provided with a mounting seat mounting structure, and the mounting seat mounting structure cooperates with the vertical mounting structure to ensure that the mounting seat 400 and the component to be tested 100 remain vertical. Specifically, the angle between the fixing portion 501 and the connecting portion 502 is set to 90°.
[0071] It is worth noting that, when the direction adjustment component 500 is connected to the mounting seat 400, the physical structure of the direction adjustment component 500 may block the terminal hole 101 of the component to be tested 100, and prevent the horizontally arranged first contact component 202 from passing through the terminal hole 101. Therefore, the direction adjustment component 500 is provided with a second avoidance structure 503, and the second avoidance structure 503 is formed as a hollow part in the middle of the direction adjustment component 500, so that the second avoidance structure 503 can avoid the terminal hole 101 that needs to be tested. Due to the setting of the second avoidance structure 503, the first contact component 202 can pass through all the terminal holes 101 and connect to the two extensions 204.
[0072] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the mounting seat installation structure includes positioning holes 504. To ensure a stable connection between the mounting seat 400 and the direction adjustment component 500, at least two positioning holes 504 are provided.
[0073] The vertical mounting structure includes a plurality of first mounting holes 402, and each first mounting hole 402 is arranged in the length direction of the mounting seat 400, and at least two first mounting holes 402 are provided. When each first mounting hole 402 is connected with each positioning hole 504, the vertical mounting structure matches the mounting seat mounting structure, and fasteners are used to pass through the first mounting holes 402 and the positioning holes 504, and a fastening effect is formed, thereby completing the connection between the mounting seat 400 and the direction adjustment component 500. Specifically, two first mounting holes 402 are provided on one side of the length direction of the mounting seat 400, and two positioning holes 504 are also provided.
[0074] Furthermore, in order to enable the tensile machine to perform tensile tests on multiple radial directions of the terminal hole 101 through the first test seat 200, the vertical mounting structure also includes a plurality of second mounting holes 403, and each second mounting hole 403 is arranged in the width direction of the mounting seat 400. The second mounting holes 403 and the first mounting holes 402 are matched with the positioning holes 504 in the same manner, thereby completing the connection between the mounting seat 400 and the direction adjustment component 500. Specifically, two second mounting holes 403 are provided on one side of the mounting seat 400 in the width direction.
[0075] It is worth noting that the two positioning holes 504 are arranged in the horizontal direction. When the mounting seat 400 is connected to the direction adjustment component 500 using the first mounting hole 402 or the second mounting hole 403, the mounting seat 400 and the component to be tested 100 are both kept upright, but there are still differences in the specific placement methods. When the mounting seat 400 is connected to the direction adjustment component 500 using only the first mounting hole 402, the length direction of the mounting seat 400 and the component to be tested 100 is horizontal, and the width direction is vertical, and each terminal hole 101 is located at the top and bottom of the mounting seat 400; when the mounting seat 400 is connected to the direction adjustment component 500 using only the second mounting hole 403, the length direction of the mounting seat 400 and the component to be tested 100 is vertical, and the width direction is horizontal, and each terminal hole 101 is located on opposite sides of the mounting seat 400.
[0076] Specifically, to ensure that the positioning hole 504 matches the first mounting hole 402 or the second mounting hole 403 , the distance between the two positioning holes 504 , the distance between the two first mounting holes 402 , and the distance between the two second mounting holes 403 are all equal.
[0077] like Figure 8 As shown, when the two positioning holes 504 match the first mounting hole 402 on one side of the length direction of the mounting seat 400, the tensile machine tests the tensile force of all terminal holes 101 in the -X direction through the first test seat 200; Fig. 9 As shown, when the two positioning holes 504 match the first mounting hole 402 on the other side of the mounting seat 400 in the length direction, the tensile machine tests the tensile force of all terminal holes 101 in the +X direction through the first test seat 200; Fig.10 As shown, when the two positioning holes 504 match the second mounting hole 403 on one side of the mounting seat 400 in the width direction, the tensile machine tests the tensile force of all terminal holes 101 in the +Y direction through the first test seat 200; Fig.11 As shown, when the two positioning holes 504 match the second mounting holes 403 on the other side of the mounting seat 400 in the width direction, the tensile testing machine tests the tensile force of all the terminal holes 101 in the -Y direction through the first test seat 200 .
[0078] In some examples, the direction adjustment component 500 is used to keep the mounting seat 400 and the DUT 100 upright. When the mounting hole matches only the first mounting hole 402 or only the second mounting hole 403, the mounting seat 400 and the DUT 100 remain upright. The word upright means extending in the vertical direction. However, upright includes not only upright but also inclined placement at a certain angle to the vertical direction.
[0079] Among them, when the mounting seat 400 and the component to be tested 100 are tilted, since the main axis of the tensile testing machine moves in the vertical direction, the tensile testing machine can perform tensile tests in other radial directions except +X, -X, +Y and -Y directions through the first test seat 200, thereby performing more directional and comprehensive tensile tests on the terminal hole 101.
[0080] Furthermore, in order to tilt the mounting seat 400 and the component to be tested 100, the two positioning holes 504 are respectively connected to a first mounting hole 402 and a second mounting hole 403, and the spacing between the first mounting hole 402 and the second mounting hole 403 used in this process is equal to the spacing between the two positioning holes 504. Since the angled position of the tilted mounting seat 400 may interfere with the relevant physical structure of the tensile test fixture, the direction adjustment component 500 or the corresponding support structure needs to be additionally provided with a structure for avoiding the angle of the mounting seat 400.
[0081] Specifically, under the premise of ensuring the spacing between the two first mounting holes 402 and the spacing between the two second mounting holes 403, according to the required tilt angle of the mounting base 400 and the component to be tested 100, the specific positions of the two first mounting holes 402 on the length direction edge of the mounting base 400 are adjusted, and the specific positions of the two second mounting holes 403 on the width direction edge of the mounting base 400 are adjusted, so as to ensure that the tilt angle of the mounting base 400 and the component to be tested 100 meets the requirements.
[0082] In addition, the number of first mounting holes 402 can be greater than two, and the number of second mounting holes 403 can also be greater than two. The second mounting holes 403 correspond one-to-one to the first mounting holes 402 and are used to match the two positioning holes 504, so that the mounting base 400 and the component to be tested 100 can achieve multiple tilt angles to ensure the diversity of the tensile test direction.
[0083] like Fig.12 and Fig.13 As shown, in some examples, the test piece mounting structure includes a third mounting hole 404, and a plurality of third mounting holes 404 are provided, respectively corresponding to a plurality of connection through holes for positioning of the component to be tested 100. When the third mounting hole 404 is connected with the connection through hole of the component to be tested 100, the mutual matching is completed and the connection is performed by the fastener.
[0084] Among them, both ends of the connecting through hole of the component to be tested 100 can match the third mounting hole 404, and the positions of each connecting through hole are symmetrical to each other, so that the component to be tested 100 can be connected to the mounting seat 400 with the front side 102 facing the mounting seat 400, or connected to the mounting seat 400 with the back side 103 facing the mounting seat 400, that is, the component to be tested 100 can be installed on both sides, which is convenient for the tensile testing machine to perform tensile testing in the +Z and -Z directions of the terminal hole 101 through the second contact component of the second test seat 300.
[0085] like Fig.14 As shown, in some examples, the tension test fixture further includes a position adjustment platform 600 , which is used to support the mounting seat 400 and the component to be tested 100 , and can adjust the horizontal positions of the mounting seat 400 and the component to be tested 100 .
[0086] The position adjustment platform 600 includes a fixed seat 601, a movable seat 602 and a platform body 603. The movable seat 602 is arranged on the top of the fixed seat 601, and the platform body 603 is arranged on the top of the movable seat 602. The fixed seat 601 and the movable seat 602 are slidably connected through a first guide assembly, so that the movable seat 602 moves in a horizontal direction; the platform body 603 and the movable seat 602 are slidably connected through a second guide assembly, so that the platform body 603 moves in a horizontal direction.
[0087] The moving directions of the moving seat 602 and the platform body 603 are at an angle, specifically, the moving directions of the moving seat 602 and the platform body 603 are 90°. The first guide assembly includes a first slide rail disposed on the fixed seat 601 and a first sliding component disposed on the moving seat 602, and the first sliding component moves along the direction of the first slide rail; the second guide assembly includes a second slide rail disposed on the moving seat 602 and a second sliding component disposed on the platform body 603, and the second sliding component moves along the direction of the second slide rail.
[0088] Since the horizontal position of the main shaft of the tensile testing machine is fixed, the position adjustment platform 600 adjusts the horizontal position of the component to be tested so that a specific terminal hole 101 corresponds to the first test seat 200 or the second test seat 300 on the main shaft of the tensile testing machine. When the terminal hole 101 for testing needs to be replaced or the position needs to be fine-tuned, the position adjustment platform 600 is also required to adjust the horizontal position of the component to be tested.
[0089] like Fig.15 As shown, the platform body 603 is connected to the horizontally placed mounting base 400 through a horizontal mounting structure. Specifically, the horizontal mounting structure includes a plurality of fourth mounting holes 405, and fasteners pass through each fourth mounting hole 405 and are fastened to the platform body 603, so that the tensile testing machine can perform tensile testing in the axial direction of the terminal hole 101.
[0090] like Fig.16 As shown, the platform body 603 is connected to the direction adjustment component 500 through the fixing part 501, so that the mounting seat 400 connected to the connecting part 502 remains upright. At the same time, the position adjustment platform 600 also includes a third connecting component 604 connected to the fixing seat 601. The structure of the third connecting component 604 is consistent with that of the first connecting component 201 and the second connecting component 301, and is installed on the steel column of the lower jaw seat of the tensile machine.
[0091] An embodiment of the present application provides a tensile testing device, including the tensile testing tooling described above.
[0092] In the actual implementation process, the tensile machine tests the tensile force in the radial direction of the terminal hole 101 through the first test seat 200, and the tensile machine tests the tensile force in the axial direction of the terminal hole 101 through the second test seat 300. The mounting seat 400 and the component to be tested 100 are combined into a whole, and the direction adjustment component 500 connects the mounting seat 400 in different ways, so that the mounting seat 400 and the component to be tested 100 are placed upright in different forms, and tensile tests are performed on multiple radial directions of the terminal hole 101. The position adjustment platform 600 is used to adjust the horizontal position of the component to be tested 100, so as to facilitate the connection of the component to be tested 100 with the first test seat 200 or the second test seat 300.
