[0001] This application relates to the technical field of tensile testing, and particularly to a tensile testing fixture and a tensile testing device. Background Art

[0002] The module tensile test mainly separates two parts of materials assembled into a module by pulling in the opposite direction. The current operation method is as follows: directly place the tensile column on the module coated with glue, then put the tensile column and the module into an oven for curing, so that the tensile column is fixed to one part of the module, and then install the tensile fixture plate so that the tensile fixture plate is fixed to the other part of the module, and then put it on the tensile platform for tensile testing. This manual connection method between the tensile column and the module itself has certain errors, and before being put into the oven, the glue has not yet cured, which is also likely to cause the center of the tensile column and the module to shift, resulting in a deviation in the connection position between the tensile column and the module finally, affecting the accuracy and consistency of the tensile test results.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0033] The following disclosure provides many different embodiments or examples for implementing different structures of the embodiments of the present application. To simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the embodiments of the present application. In addition, the embodiments of the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] For ease of description, spatial relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms such as "inner", "outer", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. This spatial relative relationship term is intended to include different orientations of the device during use or operation other than the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or motion state change, then these directional indications will also change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "over other elements or features". Therefore, the exemplary term "below" can include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0035] To solve the problems in the prior art, the present application provides a tensile test fixture and a tensile test device. The tensile test fixture can accurately control the position where the tensile column is connected to the module, thereby improving the accuracy and consistency of the tensile test results.

[0036] As Figure 1-5 shown, the embodiments of the present application provide a tensile test fixture, including a carrier 1, a positioning plate 2, and a tensile column 3.

[0037] The carrier 1 has a positioning groove 11 for positioning the module a.

[0038] The positioning plate 2 is positioned on the carrier 1, and a first positioning hole 21 corresponding to the positioning groove 11 is provided on the positioning plate 2.

[0039] The tensile column 3 is positioned in the first positioning hole 21, and the bottom of the tensile column 3 is used to connect the first part a1 of the module a.

[0040] Specifically, the module a includes a first part a1 and a second part a2 connected to the first part a1. The tensile test mainly tests the reliability of the connection between the first part a1 and the second part a2. Among them, a plurality of positioning grooves 11 are provided on the carrier 1, which can respectively position a plurality of modules a.

[0041] In this application, by positioning the positioning plate 2 on the carrier 1, the first positioning hole 21 of the positioning plate 2 is aligned with the module a on the carrier 1 to complete the positioning. After the tensile column 3 is placed in the first positioning hole 21, the positioning of the tensile column 3 is automatically completed, so as to position the connection position between the tensile column 3 and the first part a1 of the module a, and the position where the tensile column 3 is connected to the module a can be accurately controlled, thereby improving the accuracy and consistency of the tensile test results.

[0042] In the related art, when connecting the tensile column 3 and the module a at present, first, glue b is applied to the first part a1 of the module a, then the tensile column 3 is manually placed at the glue b of the module a to connect the tensile column 3 and the module a, and then the module a is moved to an oven for baking and curing. There are certain deviations when manually placing the tensile column 3, and the glue b still has a certain fluidity when it is not cured. When moving, it is easy for the tensile column 3 to shift relative to the module a, and finally the connection position between the tensile column 3 and the first part a1 of the module a is not fixed, thus affecting the accuracy and consistency of the tensile test results.

[0043] In the embodiment of this application, the module a is positioned by the carrier 1, then the positioning plate 2 is positioned and placed on the carrier 1, and the tensile column 3 is positioned through the first positioning hole 21 on the positioning plate 2, so as to ensure the consistency of the connection position between the tensile column 3 and the module a. During the process of transferring to the oven, the tensile column 3 is always positioned by the positioning plate 2, so that the situation of the position deviation of the tensile column 3 will not occur, thereby ensuring the accuracy and consistency of the tensile test results.

[0044] In some embodiments, the positioning plate 2 includes a main board body 22 and a support boss 23. The support boss 23 is provided on the side of the main board body 22 facing the carrier 1 for abutting against the carrier 1 to form a space for accommodating the module a between the main board body 22 and the carrier 1.

[0045] In this application, a certain space is reserved between the main board body 22 and the carrier 1 through the support boss 23. This space is used to accommodate the module a. The first positioning hole 21 is provided on the main board body 22. After the tensile column 3 is positioned by the first positioning hole 21 and connected to the module a, the glue b on the module a will not stick to the positioning plate 2, ensuring the connection effect between the tensile column 3 and the module a.

[0046] In some embodiments, the tension post 3 includes a positioning section 31 with the largest diameter, and the positioning section 31 is in clearance fit with the first positioning hole 21.

[0047] In this application, the diameter of the positioning section 31 is slightly smaller than the inner diameter of the first positioning hole 21. After passing the tension post 3 through the first positioning hole 21, the positioning of the tension post 3 can be completed, and the module a is positioned by the positioning groove 11, so that the connection position between the tension post 3 and the module a can be determined. The positioning section 31 has the largest diameter, which is convenient for removing the positioning plate 2 from the carrier 1 after the glue b cures, facilitating subsequent tensile testing.

[0048] In some embodiments, an inlet bevel 211 is provided at the top of the first positioning hole 21.

[0049] In this application, through the inlet bevel 211 at the top of the first positioning hole 21, it is convenient to insert the tension post 3 into the first positioning hole 21, and then the gap between the tension post 3 and the first positioning hole 21 can be made small enough to further improve the accurate consistency of the connection position between the tension post 3 and the module a.

[0050] In the related art, the tension post 3 is directly placed on the part of the module a coated with the glue b. Since the thickness of the glue b is different, the tension post 3 cannot be kept vertical after being connected to the module a, which also affects the accuracy of the tensile test.

[0051] To solve the above problems, the following embodiments are provided in this application: The tensile test fixture further includes a gravity module 4, and the gravity module 4 can be placed on the tension post 3.

[0052] In this application, after the glue b on the tension post 3 is attached to the module a, by placing the gravity module 4 on the tension post 3, the gravity of the tension post 3 is increased. The gravity module 4 also has the effect of balancing the pressure, making the thickness distribution of the glue b between the tension post 3 and the module a uniform, so as to ensure that the tension post 3 can be kept vertical after being connected to the module a, and further ensure the accuracy and consistency of the subsequent tensile test results.

[0053] Further, a second positioning hole 41 is provided along the axial direction of the gravity module 4, a first step 42 is provided in the second positioning hole 41, the tension post 3 is in clearance fit with the second positioning hole 41, and a second step 32 abuting against the first step 42 is provided on the tension post 3; wherein, when the first step 42 abuts against the second step 32, there is a gap between the gravity module 4 and the positioning plate 2.

[0054] In this application, the gravity module 4 is a cylinder, and a second positioning hole 41 is provided along its own axial direction. The top of the tension column 3 is inserted into the second positioning hole 41 to position the gravity module 4. Through the first step 42 and the second step 32, the gravity of the gravity module 4 can act on the tension column 3, and the gravity of the gravity module 4 acting on the tension column 3 can be ensured to be uniform, further ensuring the uniformity of the glue b between the tension column 3 and the module a.

[0055] In some embodiments, the tensile test fixture further includes a cover plate 5, which is positioned on the carrier 1 and is used to press the module a in the positioning groove 11.

[0056] In this application, after the module a is positioned and placed in the positioning groove 11 of the carrier 1, the module a in the positioning groove 11 is pressed by the cover plate 5, that is, the bottom of the module a is positioned by the positioning groove 11, and the upper part is pressed by the cover plate 5, thereby further improving the fixing effect on the module a.

[0057] Specifically, the module a includes a first part a1 and a second part a2. The bottom of the second part a2 is located in the positioning groove 11, and the top of the second part a2 is located outside the positioning groove 11. The cover plate 5 presses the part of the second part a2 located outside the positioning groove 11.

[0058] In some embodiments, a third positioning hole 51 is provided on the cover plate 5, a fourth positioning hole 24 is provided on the positioning plate 2, and a positioning post 12 is provided on the carrier 1. The positioning post 12 extends into the third positioning hole 51 and the fourth positioning hole 24 in sequence.

[0059] In this application, the positioning post 12 is provided at the end corner of the top of the carrier 1, which does not affect the placement of the module a. The positioning post 12 passes through the third positioning hole 51 to complete the positioning of the cover plate 5 and the carrier 1. The positioning post 12 passes through the fourth positioning hole 24 to complete the positioning of the positioning plate 2 and the carrier 1, thereby ensuring the positioning accuracy after the carrier 1, the cover plate 5, and the positioning plate 2 are arranged in sequence.

[0060] In some embodiments, an avoidance hole 52 is provided on the cover plate 5, and the avoidance hole 52 is used to avoid the coating on the module a.

[0061] In this application, the avoidance hole 52 on the cover plate 5 can avoid the coating on the module a and expose the first part a1 of the module a, so as to apply glue to the top of the first part a1 of the module a and connect the tension column 3.

[0062] In some embodiments, a handle groove is provided on the carrier 1, and through the handle groove, it is convenient to lift the upper cover plate 5, which is convenient for disassembling the relatively thin cover plate 5.

[0063] The tensile test fixture positions the positioning plate 2 on the carrier 1. The first positioning hole 21 of the positioning plate 2 is aligned with the module a on the carrier 1 to complete the positioning. After the tensile column 3 is placed into the first positioning hole 21, the positioning of the tensile column 3 is automatically completed, so as to position the connection position between the tensile column 3 and the first part a1 of the module a, and the position where the tensile column 3 is connected to the module a can be accurately controlled, thereby improving the accuracy and consistency of the tensile test results.

[0064] As Figure 6 shown, an embodiment of the present application provides a tensile test device, including: the above-mentioned tensile test fixture; the tensile column 3 of the tensile test fixture is used to connect the first part a1 of the module a, and a tensile test platform, on which a tensile fixture plate 6 is provided, and the tensile fixture plate 6 is used to connect the second part a2 of the module a.

[0065] When performing a tensile test, the module a is positioned through the positioning groove 11, and then the cover plate 5 is covered on the carrier 1 to press the second part a2 of the module a. Glue b is applied to the first part a1 of the module a, and then the positioning plate 2 is placed on the carrier 1. The first positioning holes 21 of the positioning plate 2 correspond one by one to the positioning grooves 11. Then the tensile column 3 is placed into the first positioning hole 21, and the tensile column 3 adheres to the glue b on the module a. The gravity module 4 is placed on the tensile column 3 to increase the gravity of the tensile column 3 and ensure uniform force. The carrier 1 together with the positioning plate 2 thereon is transferred into an oven to dry and cure the glue b. After taking out the carrier 1, the gravity module 4, the positioning plate 2, and the cover plate 5 are disassembled. Then the second part a2 of the module a is connected to the tensile fixture plate 6, and the tensile test platform pulls the tensile column 3 to perform a tensile test on the first part a1 and the second part a2 of the module a. The accuracy of the connection position between each group of module a and the tensile column 3 can be ensured, and further the accuracy and consistency of the tensile test results can be ensured.
